Description

  The present invention is used for placing and supporting limbs and bodies such as pillows, cushions, cushions, stools, backrests, chairs, seats, seats, sofas, beds, folding sofa beds, hammocks, stretchers, etc. It relates to a surface material of a body support device (hereinafter simply referred to as “body support device”).

The body support device is required to have air permeability and moisture absorption that do not give a feeling of stuffiness during use. For this reason, the surface material of the summer body support equipment is made of cocoon, rattan, licorice, cocoon leaf shaft, sisal hemp shaft, pineapple leaf shaft and other plant leaf stems for warp and weft. The woven / knitted fabric used is preferably used. However, plant streak is easy to corrode, unsanitary and lacks durability, the cost fluctuates depending on climatic conditions, the supply is not stable, and it is not continuous as long as plastic monofilament yarn, so it is efficient It cannot be woven or knitted, and is not suitable for mass production of the surface material of the body support device. For this reason, a polypropylene fiber and a polyester fiber are often substituted for a plant filament (for example, refer patent document 1). Polyether ester elastomer elastic yarn is known as a fiber yarn that is stable in strength (see, for example, Patent Documents 2, 3, and 4).
Japanese Patent No. 3612461 JP 2003-113551 A JP 2003-113552 A JP 2003-113553 A

However, polypropylene fibers and polyester fibers lack hygroscopicity, and a surface material having a refreshing feeling such as plant filaments such as rattan cannot be obtained. Therefore, weaving and knitting the woven and knitted fabric in a mesh shape using a thick plastic monofilament yarn made of polypropylene or polyester to ensure air permeability, but the surface of the plastic monofilament yarn is smooth and slippery. In the body support device product using the woven or knitted fabric formed as a surface material, the body slides and is not stabilized, and does not give comfort. Polypropylene fiber, polyester fiber, or polyether ester elastomer elastic yarn is a flammable substance, and is easily melted and broken when exposed to fire such as tobacco or mosquito coils.
In addition, because polypropylene fibers and polyester fibers are non-heat-absorbing / hydrophobic substances, functional paints such as anti-slip paints, fire-resistant paints, and hygroscopic paints are used like plant filaments such as rattan. It is difficult to apply functionality by coating, and the coating film is likely to be discolored and deteriorated. Particularly, in the case of a plastic monofilament yarn having a smooth surface, even if a functional paint is applied thereto, the coating is not performed. The film is easily peeled off and it is very difficult to impart functionality.

  Therefore, the present invention is provided with functionalities such as anti-slip property, fire resistance, moisture absorption, etc. equivalent to the surface material composed of plant filaments such as rattan, and is particularly suitable for summer body support devices and excellent in light resistance. Is obtained using a plastic monofilament yarn.

According to the present invention (Claim 1), even if the axial yarn 11 is composed of smooth fibers having a fineness of 200 dtex or more, the surface has fine voids between the fibers and easily absorbs moisture. Since it is covered with the multifilament yarn 12 having fine irregularities and having anti-slip properties, the shaft yarn 11 is not directly exposed to fire, and has a hygroscopic property, fire resistance and anti-slip property, and has a good surface feel. Is obtained.
Further, it is impossible to dye and print a thick plastic monofilament with a single fiber fineness exceeding 200 dtex, but a multifilament coated yarn coated with fibers that can be dyed and printed with a single fiber fineness of 20 dtex or less. The strip makes it practically possible to obtain a variety of surface materials.

  According to the present invention (Claim 2), even if the woven or knitted fabric is a mesh fabric in which the axial yarn 11 is easily exposed, the raised yarn in which the raised fluff is raised on the multifilament yarn 12 covering the axial yarn 11; When using ring yarns with surface irregularities, slab yarns, nep yarns, interlaced yarns, mole yarns with protruding piles, flocked yarns, nonwoven fabrics with lots of surface fluff, artificial leather, natural leather, etc. Alternatively, the multifilament 12 is an ethylene / vinyl acetate copolymer resin, an ethylene / methyl acrylate copolymer resin, an ethylene / acrylic acid copolymer resin, an ethylene / ethyl acrylate copolymer resin, or an ethylene / methyl methacrylate copolymer resin. As long as it has a non-slip resin such as ethylene / ethyl methacrylate copolymer resin, ethylene / methyl methacrylate / acrylic acid copolymer resin, the woven / knitted fabric 1 It accounts even less the ratio of the multi-fiber covering yarns 13, may be difficult to slip the surface member 10 by its less slip resistant multi fiber covering yarns 13.

According to the present invention (Claim 3), even if the woven or knitted fabric is a mesh fabric in which the axial yarn 11 is easily exposed, half (50%) or more of the axial yarns 11 constituting the woven or knitted fabric are made of multifilament yarn. Article 12, in particular, natural fibers such as wool fibers and silk fibers having a melting point higher than the component polymer of the shaft yarn 11, cellulosic fibers such as cocoon fibers and hemp fibers, preferably metal foil yarns, carbon fibers, graphite fibers, For flame retardant fibers treated with flame retardants such as aluminum hydroxide and ammonium polyphosphate, or multifilament yarns 12 made of flame resistant fibers kneaded with aramid fibers, glass fibers, metal fibers, metals, ceramics, etc. When the multi-fiber covered yarn 13 covered with the multi-fiber yarn 12 is formed, even if the cigarette is accidentally dropped, it is difficult to touch the shaft yarn 11.
Further, even if the woven or knitted fabric is a mesh fabric in which the axial yarn 11 is easily exposed, half (50%) or more of the axial yarns 11 constituting the woven or knitted fabric are made into the multifilament yarn 12, particularly the single fiber fineness. When the multi-fiber covered yarn 13 is coated with a multi-fiber yarn 12 consisting of ultrafine fiber of 0.5 dtex or less, hemp fiber or other cellulosic fiber, hygroscopic acrylic fiber crosslinked with a hydrazine compound, As a result, the entire surface material is hygroscopic and not stuffy.
Further, even if the woven / knitted fabric is a mesh fabric in which the axial yarn 11 is easily exposed, half (50%) or more of the axial yarns 11 constituting the woven / knitted fabric are made into the multifilament yarn 12, particularly, the wool fiber. When the multi-fiber covered yarn 13 is coated with the multi-fiber yarn 12 made of natural fiber such as silk fiber, cellulose fiber, acrylic fiber, polyester fiber, nylon, etc., the surface material 10 is dyed. Can be dyed in various colors by printing.
Thus, according to the present invention, it is possible to obtain the surface material 10 which is excellent not only in slip resistance but also in terms of tobacco fire resistance, moisture absorption, and dyeing and printing properties.

  For this reason, according to the present invention (Claim 4), the area (V) of the voids 14 of the mesh fabric is 20 to 95% (γ% = 20 to 95) of the total area of the surface material. A variety of surface materials 10 having fire resistance, anti-slip properties, or dyeing and printing properties, excellent air permeability, and suitable for summer body support devices can be obtained.

  According to the present invention (Claim 5), the covering area ratio (δ% = 100 × S / T) of the multifilament yarn 12 covering the surface of the shaft yarn 11 is 20 to 80%, On the surface of the yarn 13, the surface (26) of the smooth shaft yarn 11 is exposed in some places, and the surface material 10 that gives a refreshing feeling visually as if hitting water is obtained.

In the surface material 10 of the present invention (Claim 6), since the surface of the shaft yarn 11 is composed of a heat-fusible polymer, when the multi-fiber covered yarn 13 or the surface material 10 is heat-treated, the multi-fiber The yarn 12 is bonded and fixed to the surface of the shaft yarn 11, and the multifilament yarn 12 is not fluffed, and the surface material 10 having excellent wear resistance is obtained.
When the covering area ratio (δ% = 100 × S / T) by the multifilament yarn 12 is set to 20 to 80%, the interlaced multifilament covered yarns 13 and 13 forming the woven or knitted structure The multi-fiber covered yarn 13 and the other yarns 15 and 22 are bonded via the heat-fusible polymer on the exposed surface 26 of the multi-fiber covered yarn 13, and the woven and knitted structure is firmly established and stabilized. Become a form.
For this reason, even if the surface material is a mesh fabric in which the area (V) of the voids 14 occupies 20 to 95% (γ% = 20 to 95) of the total area, misalignment between the textures and stitches that border the voids 14 is performed. The surface material 10 suitable for a summer body support device that does not cause (organization collapse) and is rich in durability can be obtained.
According to the present invention, the presence or absence of the multifilament 12 is further removed by dissolving and removing a part of the fibers of the multifilament 12 that covers the shaft yarn 11 by printing a release agent. Even if the broken pieces of the multifilament yarn 12 that remain undissolved in the release agent and form convex portions are extremely fine, it is possible to draw an uneven pattern due to Can be bonded and fixed to the surface of the shaft yarn 11 through the conductive polymer, and the fine broken pieces do not fall off, so that the uneven pattern can be sharply drawn, and the three-dimensional and diverse surface material 10 is obtained.
In order to suppress the fluff of the multifilament yarn 12 and increase the abrasion resistance, it is possible to mix heat-fusible fibers with the multifilament yarn 12, but when the mixing rate of the heat-fusible fiber is large, The fibers of the filament yarn 12 are fused together to close the fine gaps, and the present invention is intended to give hygroscopicity and slip resistance to the smooth surface shaft yarn 11 by the fine gaps and fine irregularities between the fibers. The effect is impaired. Therefore, even if heat-fusible fibers are mixed with the multifilament yarn 12, the mixing ratio is limited to 20 to 30%.

According to the present invention (Claims 7 and 8), when the surface material 10 is a warp / wet straight insertion knitted fabric or a kneaded woven fabric, the multifilament covered yarn 13 to be knitted is a single fiber fineness of the shaft yarn 11. Is 200 dtex or more, is rigid and thick, and the surface material 10 is woven and knitted and hardly stretches in a linearly continuous direction.
Therefore, the continuous material 10 is directed to the direction in which the support and the support of the body support device face each other, and both end edges of the surface material are fixed to the facing support and the support, and the surface material 10 stretched on the body support device product. When the body is placed on the surface, the surface material 10 does not give a bottom feeling as if the surface material 10 was greatly sunk and fitted into the dent due to the acting weight.

  According to the present invention (Claim 9), the shaft yarn 11 is a monofilament single yarn having a fineness of 500 dtex or more, the tensile strength of the monofilament single yarn (11) is 2 cN / dtex or more, and the multifilament coated yarn 13 The axial yarn 11 including the yarn is continuous without being interrupted over the entire length of one or both of the length direction (W) and the width direction (C) of the fabric in the weaving and knitting process, or the length direction (W) of the fabric. 10 of the woven or knitted fabric in the continuous direction (C, W) of the axial yarn 11 including the multifilament coated yarn 13 that is intermittently continuous intermittently over the entire length of either or both of the width direction (C). Since the stress at the time of% elongation is 150 (N / 5 cm) or more, a body support apparatus product having a stable shape of the surface material can be obtained in the same manner as a body support apparatus product using rattan.

According to the present invention (Claim 10), even if the surface is formed by a rigid filament axial thread 11 made of a plastic monofilament having a single fiber fineness of 200 dtex or more, the apparent thickness of the surface is partly greater than that of the axial thread 11. The bulky yarn 17 having a thick surface and made of fibers having a single fiber fineness of 20 dtex or less is woven and knitted, so that a gentle feel is given, and the ratio of the multi-fiber covered yarn 13 in the woven and knitted fabric is given. Even if it is less, the bulky yarn 17 exhibits an anti-slip effect instead of the multifilament yarn 12, and a surface material having the required anti-slip property can be obtained.
Moreover, since the ratio of the multifilament covered yarn 13 in the woven / knitted fabric can be reduced by applying the bulky yarn 17 in this manner, the woven fabric is not particularly restricted by the ratio of the multifilament covered yarn 13. The knitted fabric can be freely designed, and various surface materials 10 can be obtained.

  According to the present invention (invention 11), in the process in which the weight acts to extend the surface material and the weight acting portion sinks (sinks), first, the multi-fiber covered yarn 13 (axial yarn) in a tension state 11) is stretched and the action part of the body weight is slightly depressed, and then the relaxed state of the multifilament covered yarn 13 (axial thread 11) is in a tension state and the action part of the body weight is slightly depressed. The action site of body weight gradually sinks stepwise over time, and does not sink suddenly, giving a feeling of bottoming and is comfortable. The surface material 10 which gives a cushion feeling is obtained.

Similarly, when the tension state of a large number of inelastic yarns 17 and 22 woven and knitted into the surface material is regularly and individually changed (Claim 12), the weight acts to extend the surface material, and the weight In the process of depression (sinking), the inelastic yarns 17 and 22 in a tensioned state are first stretched and the action part of body weight is slightly depressed, and then the inelastic yarns 17 and in a relaxed state are indented. As the body 22 is in tension and the body weight action part is slightly depressed, the body weight action part gradually declines over time, and does not sink suddenly and does not give a feeling of bottoming. The surface material 10 which gives a comfortable cushion feeling is obtained.
When the multi-fiber covered yarn 13 (shaft yarn 11) is woven and knitted together with the non-elastic yarns 17 and 22 so that the direction of the shaft core is in the same direction, the multi-fiber covered yarn is more than the non-elastic yarns 17 and 22. The strip 13 (axial yarn 11) is in a tension state inside the woven / knitted fabric.
That is, the non-elastic yarns 17 and 22 are set in a relaxed state (a relaxed state) inside the woven / knitted fabric as compared with the multifilament covered yarn 13 (axial yarn 11).
In order to keep the indentation at the position where the weight of the surface material acts on the non-elastic yarn (17, 22), the multifilament yarn or monofilament yarn, which is not a spun yarn but a long continuous fiber, is used as an inelastic yarn. Used for Article (17.22). This is because in spun yarns, which are aggregates of short fibers, when the tension acts, a gap occurs between the fibers, the action part of the weight further becomes depressed, and a slack wrinkle occurs on the surface material due to the gap between the fibers. is there.

According to the present invention (Claim 13), (1) a spun yarn, a multifilament yarn, a raised yarn in which a raised side surface of the yarn is raised and a raised fluff is raised ( 2) Ring yarn that forms an irregularity that is entangled with the core yarn in a ring shape and is raised on the circumferential side surface. (3) The yarn is entangled with the core yarn in the form of a spinning sliver and forms an irregularity that is raised on the circumferential side surface. Slab yarn, (4) Nep yarn in which the spliced yarn is entangled with the core yarn in a pill-like shape to form irregularities raised on the peripheral side surface, (5) The sheath yarn is twisted and coated on the peripheral side surface of the core yarn The floating core-sheath composite yarn, (6) The multifilament yarn is mixed with a high overfeed rate, the overfeed rate remains after twisting, and the filament fiber that sags according to the residual overfeed rate There are irregularities on the side Interlaced yarn, (7) Mole yarn in which flower yarn pieces are locked to the core yarn and projecting to the peripheral side surface in a pile shape, (8) Flocky processed yarn in which fiber fragments are electrostatically flocked to the core yarn, and (9 ) The surface of the string yarn formed by cutting a fibrous sheet containing non-woven fabric, artificial leather, and natural leather has a fine undulation due to fibers with a single fiber fineness of 20 dtex or less, giving a gentle feel. The anti-slip effect by the multifilament yarn 12 is enhanced, and as a result, the ratio of the multifilament covered yarn 13 in the woven and knitted fabric can be reduced, so that the ratio occupied by the multifilament covered yarn 13 is exceptionally restricted. Thus, a free design of woven and knitted fabrics is possible, and a variety of surface materials 10 with a soft feel can be obtained.
These yarns can be woven and knitted not as the multifilament yarn 12 constituting a part of the multifilament covered yarn 13 but as the bulky yarn 17 having a large apparent thickness independent of the shaft yarn 11. When several types of multi-fiber covered yarns 13 are used, as some of the multi-fiber yarns 12, a yarn having a fineness greater than that of the axial yarn 11 to be coated can be used.

According to the present invention (Claim 14), a thick plastic monofilament (axial yarn 11) having a single fiber fineness exceeding 200 dtex cannot be provided with functionality by post-processing, but there are many fine voids between the fibers. The filament yarn 12 is finely dispersed in an infinite number of constituent fibers without filling fine gaps between the fibers, and is anti-slip, moisture absorbent, water retention agent, flame retardant, ultraviolet absorber, antioxidant. , Light stabilizers, inhibitors, luster pigments, luminescent pigments, phosphorescent pigments, foil yarns, hygroscopic fibers, anti-slip fibers, ultrafine fibers with a single fiber fineness of 0.5 dtex or less, and so on. Thus, the surface material 10 having a high functionality and a design that is not obtained by using the fibrous plant filaments that are the leaf stems of conventional cocoons, rattans, and other plants can be obtained.
And as functional compounds such as anti-slip agents, hygroscopic agents, water retention agents, flame retardants, UV absorbers, antioxidants, light stabilizers, inhibitors, bright pigments, luminescent pigments, phosphorescent pigments, etc. are given together with binder resins. However, they are adsorbed and held in fine voids between the fibers of the multifilament 12, and the coating film does not peel off.
In particular, by application of phenol-based or sulfur-based UV absorbers and antioxidants, and hindered amine light stabilizers, and because they are concealed in the multifilament 12 carrying them, their functionality Even if it is difficult to knead and spin the compound into the shaft yarn 11, discoloration / fading of the shaft yarn 11 is prevented, and the surface material 10 is excellent in light resistance and suitable for a summer body support device.

  According to the present invention (Claim 15), the polyetherester elastomer elastic yarn is less likely to stretch than the polyurethane elastic yarn (spandex) and other elastic yarns. Even if it does, the surface material 10 which does not generate | occur | produce an expansion / contraction wrinkle is obtained.

The surface material 10 of the present invention comprises: (a) a weaving / knitting density in which a shaft yarn 11 formed of a plastic monofilament having a single fiber fineness of 200 dtex or more appears in a unit section (4 cm ² ) defined with dimensions of 2 cm in length and width. (B) a multifilament yarn whose surface is constituted by fibers having a single fiber fineness of 20 dtex or less. (C) a multi-fiber covered yarn 13 whose axial yarn 11 is covered with a multi-fiber yarn 12 is exposed in the unit section. However, in order to be able to be used by stretching between the supports like the surface material of rattan furniture, the length direction (W) and the width direction (C) in the weaving and knitting process At least any of Stress at 10% elongation of the textile fabric in one direction shall have a physical strength to be 150 (N / 5cm) than naturally.
As such, the required physical strength of the body support device depends on the warp density and weft density for woven fabrics, the wale density and the coarse density for knitted fabrics, the fineness of warp and weft yarns including the axial yarn 11, the type of material fiber, and the like. Set as appropriate.
The surface material is required to have air permeability that does not give a feeling of stuffiness during use. The woven / knitted fabric has a coarse woven / knitted density, the woven fabric generally has a warp density and a weft density of 10 pieces / cm or less, Generally, it is preferable to set the wale density to 10 wales / cm or less and the course density to the course / cm or less. In addition, the stress (unit: N / 5cm) at the time of 10% expansion | extension of a woven / knitted fabric is measured by the test method prescribed | regulated to JIS-L-1096.

When the woven or knitted fabric is a mesh fabric in which the gap 14 appears in the unit section, the exposed area (A) of the multifilament covered yarn 13 exposed and occupied in the unit section is determined from the area (4 cm ² ) of the unit section. The ratio of the occupied area of the multifilament covered yarn (α% = 100 × A / B) in the total fiber area (B = 4 cm ² −V) minus the area (V) occupied by 14 is preferably 20% or more.
Then, even when the woven / knitted fabric is a mesh fabric and the total area (B) occupied by the fibers decreases relative to the area (V) occupied by the voids 14, 20% or more of the total area (B) occupied by the fibers (Α% = 100 × A / B ≧ 20) is occupied by the multifilament-coated yarn 13, so that the hygroscopicity, fire resistance, anti-slip property, or dyeing and printing of the surface material wrinkled by the coated multifilament yarn 12 The surface material 10 suitable for the body support device for summer is obtained without impairing effects such as sex.

Further, when the woven or knitted fabric is a mesh fabric in which the gap 14 appears in the unit section, the uncovered exposed area (C) that the uncoated shaft yarn 11 that is not covered with the multifilament yarn 12 is exposed in the unit section. ) Is preferably 20% or less of the uncoated axial yarn occupation area ratio (β% = 100 × C / B) in the total fiber area (B = 4 cm ² −V) in the unit section.
As a result, the total area (B) occupied by the fibers is small relative to the area (V) occupied by the air gap 14, and the uncoated axial yarn in the state of the axial yarn 11 that is not covered with the multifilament yarn 12 on the woven or knitted fabric. Is the ratio of the uncovered exposed area (C) occupied by the uncoated shaft yarn 11 to the total area (B) occupied by the fibers on the surface of the woven or knitted fabric (β% = 100 × C / B) If it is 20% or less, the effects of moisture absorption, fire resistance, anti-slip property, dyeing and printing, etc. of the surface material wound by the multifilament yarn 12 covering the shaft yarn are impaired by the uncoated shaft yarn 11. Such a thing does not happen.
That is, the range in which the multi-fiber covered yarn occupation area ratio (α) is 20% or more and the uncoated shaft yarn occupation area ratio (β) is 20% or less, that is, the occupation area of the uncoated shaft yarn 11 is not covered. The use of the uncoated shaft yarn 11 is recognized within a range of 50% or less of the occupied area of all the shaft yarns 11 including the shaft yarn 11 and the shaft yarn 11 of the multi-fiber coated yarn 13.

In the present invention, “woven / knitted fabric” means both a woven fabric and a knitted fabric, and “woven / knitted” means both woven fabric by a loom and knitted fabric by a knitting machine. In the present invention, the total area of fibers (B) obtained by subtracting the area (V) occupied by the voids 14 from the exposed area (A) of the multifilament covered yarn 13 exposed and occupied in the unit section and the area (4 cm ² ) of the unit section. = 4 cm ² -V) and the area ratio (α% = 100 × A / B) is 20% or more means that the remaining surface portion of the woven or knitted fabric in which the ratio (α) is less than 20% (100−α <80%) can be constituted by yarns 15 and 23 other than the multifilament coated yarn, and the surface of the woven or knitted fabric is multifilament coated so that the ratio (α) becomes 100%. It means both that it can be constituted only by the yarn 13.
That is, in the present invention, “axial yarn is woven and knitted” means a woven / knitted fabric using only the axial yarn 11 including the multifilament covered yarn 13 and the axial yarn 11 including the multifilament covered yarn 13. Both woven and knitted fabrics using a part of Here, the “surface of the woven or knitted fabric” means the surface of the woven or knitted fabric that appears on the outer surface of the body supporting device when attached to the body supporting device.
Further, the exposed area (A) of the multifilament coated yarn 13, the total fiber area (B) after subtracting the area (V) occupied by the gap 14, or the uncovered exposed area (C) occupied by the shaft yarn 11 exposed. The “area” means the area occupied by the fibers and yarns constituting the woven or knitted fabric depicted in the surface view representing the woven or knitted fabric in the surface view. The same applies to the “area” (V).

In the present invention, the “unit section” of the woven or knitted fabric that defines the multi-fiber covered yarn occupation area ratio (α), the uncoated axial yarn occupation area ratio (β), and the void occupation area ratio (γ) is a rectangle of 2 cm in length and width. The reason for setting the section is to define the distribution state in which the multi-fiber covered yarn 13, the uncoated shaft yarn 11, or the gap 14 are finely and evenly distributed over the entire surface of the woven or knitted fabric. Therefore, in order to improve the uniformity of the quality of the surface material 10, the “unit section” is a rectangular section (1 cm ² ) of 1 cm in length and width, and the area occupied by the multifilament covered yarn in the “unit section (1 cm ² )”. It is desirable to set (α), the uncovered axial yarn occupation area ratio (β) and the void occupation area ratio (γ).
In the present invention, the “unit section” is defined as a rectangular section having a length and width of 2 cm, and repeats (repetitive unit dimensions), such as a ground pattern of a mesh fabric drawn according to the outline and shape type of the gap 14. For woven and knitted fabrics with a ground pattern exceeding 1 cm and voids (14) with an opening internal dimension exceeding 1 cm, assuming that the vertical and horizontal dimensions of the “unit section” are 1 cm, the woven / knitted density and the occupied area ratio of the multifilament covered yarn This is because inconvenience arises in specifying (α), the uncovered axial yarn occupation area ratio (β), and the void occupation area ratio (γ).

  Woven knitting means that the multi-fiber covered yarn occupation area ratio (α) is 20% or more, the uncoated shaft yarn occupation area ratio (β) is 20% or less, or the void occupation area ratio (γ) is 20 to 95%. Even if it is measured in any part of the fabric, that is, in any part of the woven or knitted fabric, the occupied area ratio (α) of the multi-fiber coated yarn is 20% or more, and the uncoated shaft yarn is occupied. It means that the area ratio (β) is 20% or less, or the void occupation area ratio (γ) is 20 to 95%. However, this means that the multifilament covered yarn occupied area ratio (α), the uncoated axial yarn occupied area ratio (β), and the void occupied area ratio (γ) in any part of the woven or knitted fabric have the same value. This means that differences and variations in the ratio between these measurement parts are allowed.

  In the present invention, a yarn formed of a plastic monofilament having a single fiber fineness of 200 dtex or more is expressed as an “axial yarn” because the plastic monofilament having a single fiber fineness of 200 dtex or more is formed by fibers having a single fiber fineness of 20 dtex or less. This is because it is very stiff compared to general yarns such as multifilament yarns and spun yarns, and has a rod or shaft shape, and a yarn consisting of plastic monofilaments with a single fiber fineness of 200 dtex or more is expressed as "monofilament yarn". The reason for not doing so is to avoid misunderstanding as if the “axial yarn” in the present invention also includes a yarn composed of a plurality of plastic monofilaments, and that means only “monofilament single yarn”.

A monofilament having a single fiber fineness of 200 dtex or more is used as the axial yarn 11, but the axial yarn 11 may be composed of a plurality of monofilaments having a single fiber fineness of 200 dtex or more. However, in order to increase the air gap occupying area ratio (γ) and improve the air permeability of the woven or knitted fabric, the axial yarn 11 may not be constituted by a plurality of monofilaments but may be constituted by monofilament single yarns having a fineness of 500 dtex or more. Desirably, by making the shaft yarn 11 a monofilament single yarn having a fineness of 500 dtex or more, the shaft yarn 11 is covered with a relatively low-volume multifilament yarn, and the bulk of the multifilament-covered yarn 13 is increased. The air permeability of the woven or knitted fabric can be increased by lowering.
In that respect, it is desirable that the ratio of the multifilament yarn 12 in the multifilament-coated yarn 13 is less than 30% by mass. That is, the total fineness of the multifilament yarn 12 is set to 60% or less of the total fineness of the shaft yarn 11, preferably 25% or less, more preferably 10% or less.
If the use ratio of the multifilament yarn 12 is reduced in such a manner, the multifilament covered yarn 13 does not have water retention or moisture absorption more than necessary, and the surface material 10 dries quickly when wet with rain water or after washing with water. This is advantageous.

A multifilament yarn or spun yarn having a single fiber fineness of 20 dtex or less is used for the multifilament yarn 12 or the bulky yarn 17, and the surface of the yarn is composed of fibers having a single fiber fineness of 20 dtex or less. As long as it is, a flocky yarn in which chenille yarn or pile fiber is electrostatically flocked, a string yarn formed by cutting a fibrous sheet such as a nonwoven fabric or leather (natural leather, artificial leather) into a narrow width can be used. .
In that case, the fiber sheet which comprises the multifilament yarn 12 and the bulky yarn 17 shall use the fiber of the single fiber fineness of 20 dtex or less as at least one part raw material. In order to sufficiently cover the shaft yarn 11 with a small use ratio of the yarn 12 that is 25% or less of the total fineness of the shaft yarn 11, an extra fine fiber having a single fiber fineness of less than 0.5 dtex is applied to the multifilament 12. It is good to use.

The multi-fiber covered yarn 13 is prepared by supplying the multi-fiber yarn 12 to the air box and allowing the multi-fiber yarn 12 to be entangled with the shaft yarn 11 in the process of passing the shaft yarn 11 through the rotating air box. I can do it.
The covered area ratio (δ%) of the covered area (S) occupied by the partially covered multifilament yarn 12 with respect to the surface area (T) of the shaft yarn 11 as in the multifilament covered yarn 13 shown in FIG. = 100 × S / T) to 20 to 80%, in the process of passing the shaft yarn 11 through the hollow shaft core of the rotating cone with the multifilament yarn 12 wound up, the multifilament yarn from the cone The strip 12 may be supplied and wound around the shaft yarn 11, and at that time, the covering area ratio (δ) can be adjusted by the rotation speed of the cone and the speed at which the shaft yarn passes through the cone.
As in the case of the multifilament coated yarn 13 shown in FIG. 2, in the process in which the shaft yarn 11 and the multifilament yarn 12 are passed through the hollow shaft core of the cone which is wound with the binding yarn 18 and rotated, the cone Thus, the binding yarn 18 can be supplied to and wound around the axial yarn 11 and the multifilament yarn 12, and the axial yarn 11 and the multifilament yarn 12 can be bound by the binding yarn 18.
The multifilament yarn 12 has a constant tensile strength like a general yarn such as a multifilament yarn or a spun yarn, but also has short fibers arranged like a sliver sent out from a spinning card. It may have almost no tensile strength.

The weft insertion warp knitted fabric applied to the surface material 10 is described in Japanese Patent Application Laid-Open No. 11-279907 and Japanese Utility Model Publication No. 3-29320. FIG. 4 shows a weft insertion warp knitted fabric (10) formed by inserting the axial yarn 11 and the multifilament covered yarn 13 as a weft in a straight line in the course direction C of the base knitted fabric 16 knitted by a warp knitting machine. FIG. 3 shows a base knitted fabric 16 into which the axial yarn 11 and the multifilament covered yarn 13 are knitted.
The warp insertion warp knitted fabric applied to the surface material 10 is also disclosed in JP-A-11-279907 and JP-A-3-29320. In the warp insertion warp knitted fabric, the warp (11) is inserted in a straight line in the wale direction (W) of the base knitted fabric knitted by the warp knitting machine.
The weft insertion weft knitted fabric applied to the surface material 10 is described in Japanese Patent Publication No. 58-7738. FIG. 6 shows a weft insertion weft knitted fabric in which a multi-fiber covered yarn 13 is inserted in a straight line as a weft in the course direction C of a base knitted fabric 16 knitted by a flat knitting machine. A base knitted fabric 16 into which the multifilament covered yarn 13 is knitted is shown.
Thus, the warp / weft straight insertion knitted fabric applied to the surface material 10 is knitted by inserting the multi-fiber covered yarn 13 in a straight line in the course direction (C) or the wale direction (W) in a known knitted fabric. I can do it.

In the surface material 10 of the present invention, the yarn 13 (11) is “intermittently discontinuous” means, as in the warp knitted fabric shown in FIG. 7, the width direction of the woven / knitted fabric (course direction C). The yarns 13 arranged at regular intervals are woven into a woven or knitted fabric zigzag while vibrating in the left-right width direction (course direction C), and the left and right turning points 19 and 20 are turned back and forth by vibrating left and right. It means that the yarn 13 is in a straight line.
More specifically, in FIG. 7, the yarn 15 is knitted, and the chain stitch row 21 and the chain stitch row 21 that are adjacent to each other in a straight direction in the wale direction W are knitted while vibrating in the width direction (course direction C). The insertion yarn (13) in the warp knitted fabric that is connected and knitted by the yarn (13) corresponds to “intermittently continuous yarns”.
In the present invention, the multi-fiber covered yarn 13 can also be applied to the insertion yarn that connects the chain stitch rows 21 and 21. In that case, it is not always necessary to apply the multifilament covered yarn 13 to the ground yarn 15 constituting the chain stitch row 21.

In the present invention, “a woven or knitted fabric in which shaft yarns are knitted and knitted” or “an occupied area ratio (α) of an exposed area (A) of a multifilament covered yarn is 20% or more” is a surface material. 10 means that there is room for using other yarns of the shaft yarn 11 and the multi-fiber covered yarn 13.
Specifically, the warp knitted fabric (the warp knitted fabric 15 or the warp knitted fabric (FIGS. 4 and 6) constituting the base knitted fabric 16 or the warp knitted fabric formed by connecting the chain stitch rows with the insert yarn ( In FIG. 7), the ground yarn 15 constituting the chain stitch row 21 and the warp of the fabric such as the core warp 23a and the warp warp 23b of the kneaded fabric (FIG. 2) for locking the multifilament covered yarn 13 are used. It means that the other yarns 15 and 23 of the shaft yarn 11 and the multi-fiber covered yarn 13 can be used for one of the weft yarns.

Furthermore, in the present invention, “at least a part of the axial yarn appearing in the unit section is covered with the multifilament yarn” or “occupied area ratio area ratio (α) of the exposed area (A) of the multifilament covered yarn” "20% or more" means that even if the multi-fiber covered yarn 13 is applied to the warp / weft straight insertion knitted fabric, the warp knitted fabric, and the woven fabric, the multi-fiber covered yarn 13 is expected to be used. It also means that not a multi-fiber covered yarn 13 but a yarn other than the multi-fiber covered yarn (13) can be used in a part of the woven or knitted fabric.
More specifically, a yarn different from the axial yarn 11 and the multifilament covered yarn 13 is used for the core warp 23a and the kneaded warp 23b of the kneaded fabric (FIG. 2), and the multifilament covered yarn 13 is used for the weft. When wefts are woven sequentially in the process of weaving the kneaded woven fabric, the multi-fiber covered yarns 13 and the other yarns 17 are alternated with each other, or one of the yarns is numbered. It also means that weaving is alternated so that the other thread is weaved every time weaving.
This also applies to knitted fabrics. For example, when the multi-fiber covered yarns 13 are sequentially knitted as in the knitted fabric shown in FIGS. 1 and 7, the multi-fiber covered yarns 13 are knitted. In some planned courses, the thin yarn 22 or the bulky yarn 17 can be knitted in place of the multi-fiber covered yarn 13.

As described above, “other yarns” woven and knitted alternately with the multi-fiber covered yarn 13 are the thin yarn 22 (FIG. 1), the bulky yarn 17 (FIG. 2), or the uncoated shaft yarn 11 (FIG. 4). It may be. In the present invention, the uncovered axial yarn occupation area ratio (β) in the total fiber area (B = 4 cm ² −V) of the uncovered exposed area (C) that the uncoated shaft yarn 11 is exposed in the unit section. 20% or less (β ≦ 20%) means that the total area occupied by the fibers even when the total area (B) occupied by the fibers is smaller than the area (V) occupied by the voids 14 in the unit section As long as 20% or more (α% = 100 × A / B ≧ 20) of (B) is occupied by the multifilament covered yarn 13, 20% of the axial yarn 11 that is not covered by the multifilament yarn 12 in the unit section (β Even if it is exposed to the extent of .ltoreq.20%), the hygroscopicity, fire resistance, anti-slip property, and dyeing / printing property that are given to the woven or knitted fabric (10) by the multifilament yarn 12 are not impaired so much.

  In the present invention, the ratio (β% = 100 × C / B) of the uncovered exposed area (C) occupied by the uncoated shaft yarn 11 to the total area (B) occupied by the fibers on the surface of the surface material is 20%. A certain amount of uncoated shaft yarn 11 is allowed to be used, and the ratio of the multi-fiber covered yarn occupied area (α) occupied by the multi-fiber covered yarn 13 to the total area (B) occupied by the fiber is about 20%. The use of other general yarns that are neither the uncoated shaft yarn 11 nor the multi-fiber coated yarn 13 is permitted because the woven or knitted fabric of the woven or knitted fabric as a product is the shaft yarn 11 (uncoated shaft). It is often necessary to use other general yarns when it is intended to be composed of yarn and multi-fiber covered yarn), and only the axial yarn 11 (uncoated axial yarn and multi-fiber covered yarn) is used. This is because it may be difficult to design a product that meets demand.

In particular, when a surface material is to be designed with a few types of axial yarns 11 (uncoated axial yarns and multi-fiber coated yarns) limited by specifications such as fineness and material (fiber material), the axial yarn 11 ( In order to supplement specifications such as fineness and material (fiber material) of uncoated shaft yarn and multifilament coated yarn, it is necessary to use other general yarns.
A weft chain warp knitted fabric in which the wefts 13 arranged in parallel shown in FIG. 1 are connected by a chain stitch row 21 of the base yarn 15, a knit fabric shown in FIG. 2, a weft insertion warp knitted fabric shown in FIG. The weft insertion weft knitted fabric shown in FIG. 6 is a good example.
In these surface materials, the wefts arranged on the entire surface constitute the main part of the woven / knitted fabric, and the base yarn 15 (base knitted fabric 16) and the warp yarn 23 are the axial yarns 11 (uncoated) arranged on the entire surface as the weft. Auxiliary means for maintaining the alignment state of the shaft yarn and the multi-fiber coated yarn).

That is, in those surface materials, the axial yarn 11 (uncoated axial yarn and multifilament covered yarn) constituting the main body has a fineness of 500 dtex or more and is difficult to bend and forms a rigid rod or shaft rod. However, since it is woven and knitted in the state of a straight rod or shaft that is continuous in a straight line without bending, it can be easily applied to woven and knitted fabrics.
However, the base knitted fabric 16 and the chain stitch row 21 of these surface materials are formed by a needle loop 24 and a sinker loop 25 in which the ground yarn 15 is bent, and in a woven fabric, the knitted fabric is bent and driven to form an opening. Since the weft yarns (11, 13) are locked by the warp yarn 23, flexible yarns having a single fiber fineness of less than 200 dtex are used for the ground yarn 15 and the warp yarn 23, and the fineness is 500 dtex or more. It is difficult to use the axial yarn 11 (uncoated axial yarn and multi-fiber coated yarn) which is in the form of a rigid rod or shaft rod that is difficult to bend.
Therefore, as an auxiliary means for forming a woven structure or a knitted structure and maintaining the arrangement state of the axial yarns (uncoated axial yarns and multifilament coated yarns), a flexible yarn having a single fiber fineness of 20 dtex or less. Need to be used.

Depending on the few types of axial yarns 11 (uncoated axial yarns and multifilament coated yarns) limited by specifications such as fineness and material (fiber material), the weft density of the surface material can be set according to demand. In some cases, it may be necessary to use other general yarns (17, 22) in order to supplement the physical properties of the surface material by the shaft yarn 11 (uncoated shaft yarn and multi-fiber coated yarn). .
For example, in order to ensure the anti-slip property of the surface material, a bulky yarn 17 such as a chenille yarn excellent in anti-slip property than a multifilament coated yarn or a fiber tape yarn obtained by cutting a nonwoven fabric or leather into a tape shape 17 (Fig. 2) is required, and when the stress at the time of 10% elongation of the surface material is more than necessary, for example, 5000 (N / 5 cm) or more, a general yarn having a tensile strength higher than that of the multifilament covered yarn. In some cases, a strip is required as a pseudoaxle.
Further, the woven / knitted fabric is coarsely woven / knitted, the warp density and the weft density are set to 10 / cm or less for the woven fabric, the wale density is set to 10 / mm / cm or less for the knitted fabric, and the course density is set to the course / cm or less. In the case of using a thick shaft yarn 11 having a fineness of 1000 dtex or more similar to the fibrous plant filaments that form the stems of cocoons, rattan, licorice, cocoon leaf shafts, sisal hemp shafts, pineapple leaf shafts and other plants, In order to ensure the air permeability of the surface material, it may be necessary to use a fine yarn 22 (FIG. 1) having a fineness smaller than that of the multifilament covered yarn 13.
As described above, “other yarns” woven and knitted alternately with the multi-fiber covered yarn 13 are the thin yarn 22 (FIG. 1), the bulky yarn 17 (FIG. 2), or the uncoated shaft yarn 11 (FIG. 4). It may be.
Further, the “other yarns” woven and knitted alternately with the multi-fiber coated yarn 13 are composed of axial yarns made of plastic monofilaments having a single fiber fineness of 200 dtex or more and fibers made of fibers having a single fiber fineness of 20 dtex or more. A multi-filament yarn, or a tape-like string yarn having a fine cross-section having a fineness of 200 dtex or more formed by cutting a fibrous sheet containing non-woven fabric, artificial leather, or natural leather, a flat cross-section monofilament yarn (so-called tape yarn) having a fineness of 200 dtex or more, It may be a flat section foil yarn having a fineness of 200 dtex or more.

As described above, when the bulky yarn 17, the fine yarn 22, or other general yarn is applied as a complementary means for the multifilament covered yarn 13, the stripe ( The regular yarns (17, 22) and the multifilament covered yarns 13 or the uncoated axial yarns 11 are woven and knitted regularly and alternately with the required repeat (repetition) so that a stripe pattern is drawn. Is recommended.
As the shaft yarn 11, in addition to polypropylene fiber and polyethylene fiber, nylon, vinyl chloride fiber, polyetherester fiber, trimethylene terephthalate fiber, tributylene terephthalate fiber, etc. have a tensile strength of 2.0 cN / dtex or more and are elastic. Hydrophobic fibers may be used.
A preferred shaft yarn 11 is a low-melting-point polyether ester comprising a high-melting-point polyether ester elastomer disclosed in JP-A-11-350297, JP-A-2000-160453, and JP-A-2000-248450 as a core component. It is a heat-sealable core-sheath composite polyetherester elastomer elastic yarn having a base elastomer as a sheath component.
However, polyurethane fiber (spandex) is easy to stretch and has a tensile strength of less than 2.0 cN / dtex, and the woven or knitted fabric using it as an axial thread sinks greatly when the limb is placed on it, and the support state of the limb is reduced. Since it becomes unstable, it is not preferable as the axial thread 11.

A preferred surface material is a woven or knitted fabric that stretches moderately according to the weight supported during use, gives a feeling of cushioning, has a small elongation rate, does not give a feeling of bottom hitting, shrinks after use and restores its original shape, and does not leave any elongation wrinkles It is. In that respect, the use of polyetherester elastic fiber having a tensile strength equivalent to that of acrylic fiber, vinylon fiber, etc., in particular, core-sheath composite polyetherester elastic fiber having a heat-fusible polymer as a sheath component for the shaft yarn. Is desirable.
In this case, the multifilament covered yarn 13 is such that the multifilament yarn 12 partially covers the shaft yarn 11, the shaft yarn is partially exposed, and the multifilament yarn is in relation to the surface area (T) of the shaft yarn. 12 is a partially covered yarn (FIGS. 1 and 2) in which the covering area ratio (δ% = 100 × S / T) of the covering area (S) that is partially covered and covered is 20 to 80%, The axial yarn 11 is a monofilament single yarn having a fineness of 500 dtex or more, and the tensile strength of the monofilament single yarn (11) is 2 cN / dtex or more, which is the fabric length direction (W) and width direction (C ) Continuously without any interruption over the entire length of one or both of them, or intermittently continuous over the entire length of one or both of the length direction (W) and width direction (C) of the fabric, Woven knitted fabric in the continuous direction (C, W) of the shaft yarn 11 The stress at the time of 10% elongation is 150 (N / 5 cm) or more, and the shaft yarn 11 is adhered to the other yarns 15 and 23 on the exposed surface 26 of the shaft yarn 11 not covered with the multifilament yarn 12. Thus, the surface material 10 having excellent shape stability and cushioning properties can be obtained.

In order to give a moderate cushion feeling by appropriately extending the weight of the surface material when it is used, the surface material is made of woven fabric or warp / weft straight insertion knitted fabric (weft insertion warp knitted fabric, warp insertion warp knitted fabric, A plurality of multi-fiber covered yarns 13a, 13b, 13c, 13d, 13e / 13a, 13b, 13c, 13d, 13e / which are repeatedly weaved in a straight line. 13a, 13b, 13c, 13d, 13e / ... Multi-fiber covered yarn woven into a predetermined region (dimension) of a woven / knitted fabric by changing the tension acting on the woven / knitted fabric The lengths (dimensions) of the strips 13a, 13b, 13c, 13d, and 13e may be changed.
In other words, the degree of relaxation of the multifilament covered yarns 13a, 13b, 13c, 13d, and 13e woven and knitted into a predetermined region (dimension) of the woven / knitted fabric is changed.
Specifically, when the length of the multifilament covered yarns 13a and 13b woven and knitted in a predetermined region (dimension) of the woven / knitted fabric is Acm, the length of the multifilament covered yarns 13c and 13d is as follows. Is (A-ε) cm, and the length of the multifilament covered yarn 13e is (A-2ε) cm.

That is, in a predetermined region (dimension) of the woven / knitted fabric, the multi-fiber covered yarn 13e is in a tensioned state, the multi-fiber covered yarns 13c and 13d are often in a tensioned state, and the multi-fiber covered yarns 13a and 13b are in tension. Changes the degree of relaxation so that it is in a relaxed state.
Then, in the process in which the weight acts and the surface material extends, and the action portion of the weight sinks (sinks), first, the multi-fiber covered yarn 13e that is in a tension state is stretched and the action portion of the weight is slightly depressed, Next, the multi-fiber covered yarns 13c and 13d, which were often in a tension state, were stretched in a tension state, the action part of the weight was further depressed, and then the multi-fiber covered yarns 13a and 13b in a relaxed state were in tension. As the state becomes stretched and the action part of the body weight is further depressed, a plurality of multi-fiber covered yarns 13a, 13b, 13c, 13d, and 13e are successively extended over time, and the action part of the body weight is increased. The body does not sink suddenly and gives a feeling of bottoming, and the body weight action portion gradually becomes depressed gradually over time, giving a comfortable cushion feeling.

For this purpose, an elastic yarn having an elastic recovery rate of 95% or more and approximately 100% after elongation of 10% is used for the shaft yarn 11, and in particular, a multifilament that is most stretched in a tension state. The shaft yarn 11 of the coated yarn 13e is an elastic yarn that is stretched during the weaving and knitting process and is put in a tension state in the woven or knitted fabric after weaving. More preferably, the woven or knitted fabric is heated to be stronger after weaving. It is desirable to use heat-shrinkable elastic yarns that can be placed in tension.
However, the shaft yarn 11 of the multi-fiber covered yarns 13a and 13b which are in a relaxed state and will not be stretched to a great extent, has the multi-fiber coated yarn 13e which is most likely to be stretched in a tension state. It is desirable to use a yarn that has a large tensile strength and is difficult to extend as compared to the shaft yarn 11.
In particular, the multi-fiber covered yarn 13e of the multi-fiber covered yarn 13e that is most likely to be stretched in a tensioned state also prevents the stretchability of the axial yarn 11 from being hindered. It is desirable that the ratio of the multifilament yarn 12 occupying the stripe 13 is less than 30% by mass.
That is, the total fineness of the multifilament yarn 12 is set to 60% or less of the total fineness of the shaft yarn 11, preferably 25% or less, more preferably 10% or less.

The surface material is stretched with sufficient tension between the supports of the body support device so as not to be greatly depressed. The fiber-coated yarn 13 does not extend greatly, and the elongation rate is less than 5%.
Therefore, even if the lengths (dimensions) of the plurality of multifilament covered yarns 13a, 13b, 13c, 13d, and 13e that are repeatedly woven and knitted in a straight line are changed, the difference between the lengths (φ% = 100 × ε / A) may be less than 5% and generally around 3%.

In addition to the multi-fiber covered yarn 13, the shaft yarn 11, the bulky yarn 17, the fine yarn 22 and other single fiber finenesses are as in the woven fabric and warp / weft straight insertion knitted fabric shown in FIGS. When flexible general yarns that become fibers of less than 200 dtex are repeatedly woven and knitted in a straight line, when the length of the general yarns 17 is Acm, the length of the other general yarns 22 is (A −ε) cm, the length of the shaft yarn 11 and the multifilament covered yarn 13 is (A−2ε) cm.
That is, in a predetermined region (dimension) of the woven / knitted fabric, the shaft yarn 11 and the multi-fiber covered yarn 13 are in a tension state, the general yarn 22 is often in a tension state, and the other general yarns 17 are relaxed. Change the degree of relaxation so that it is in a state. Therefore, in order to effectively carry out the present invention, at least the shaft yarn (11 · 13) and the general yarn (17 · 22) whose shaft cores are oriented in the same direction in the woven or knitted fabric are at least stretched. Several types of yarns that differ in either elasticity or heat shrinkability are used, and several types of yarns with different degrees of tension and relaxation in the woven or knitted fabric after weaving have their axes oriented in the same direction. Intervene.
More preferably, depending on the degree of tension in the woven or knitted fabric after weaving and knitting, several types of yarns that differ in both stretch elasticity and heat shrinkability are used for the shaft yarn 11.

An elastic yarn is used for the shaft yarn 11 (multi-fiber coated yarn 13), and non-elastic yarns for the general yarns 17 and 22, especially spun yarns and multifilament yarns that are inelastic crimped fibers, A multifilament crimped yarn may be used. The elongation strain caused by the tension applied during the knitting process is not particularly stretched during the knitting process relative to the elastic shaft yarn 11 (multi-fiber covered yarn 13) that elastically resolves and contracts after weaving. This is because the general yarns 17 and 22 are loosened.
In that case, the total fineness (so-called total denier) of the general yarns 17 and 22 is made thicker than that of the elastic shaft yarn 11 (multi-fiber coated yarn 13), and the weight acts to extend the surface material. In the process of sinking (sinking), first, the elastic shaft yarn 11 (multi-fiber coated yarn 13) that was in tension was stretched, and then one of the general yarns 17 was stretched, and the other was in the most relaxed state. The general yarn 22 is in a tension state to suppress the elongation of the elastic shaft yarn 11 (multi-fiber-coated yarn 13), so that the portion where the weight acts is not depressed more than necessary.

  The multifilament 12 includes aluminum hydroxide, ammonium polyphosphate and other flame retardants, ethylene / vinyl acetate copolymer resin, ethylene / methyl acrylate copolymer resin, ethylene / acrylic acid copolymer resin, and ethylene / ethyl acrylate. Copolymer resin, ethylene / methyl methacrylate copolymer resin, ethylene / ethyl methacrylate copolymer resin, anti-slip agent mainly composed of anti-slip resin such as ethylene / methyl methacrylate / acrylic acid copolymer resin, gelatin, pulp, Wood powder, cellulose powder and other water retention agents, silica gel and other moisture absorbents, activated carbon, hydrous magnesium silicate clay mineral, amide phosphazene compound, hydrazide compound, zinc compound, metal phthalocyanine and other deodorants, chitosan, zinc alloy, chloride Benzalkonium, Benzethonium chloride, 2, 4, 4 -Trichloro-2'-hydroxydiphenyl ether, polylysine compounds and other antibacterial or antifungal agents, pyrethroids, di-normal propyl isochincomeronate, 2-hydroxyethyl octyl sulfide, diethyl toluamide, dimethyl phthalate, isopropyl-2- [ [Ethoxy (isopropylamino) thiophosphoryloxy] benzoate, other insect repellents, natural fragrances, diphenyl oxide, jasmon, heliotropin, vanillin, coumarin and other fragrances, pearl pigments, metal powder, mica, foil powder, glass beads, etc. Functional materials such as glitter glitter and antistatic agents obtained by pulverizing glitter sheets such as glitter pigments, luminescent pigments, phosphorescent pigments, metal foils, metal-deposited films, and photographic films.

  The multifilament yarn 12 is subjected to a crosslinking treatment with foil yarn obtained by cutting a glitter sheet such as ultrafine fiber having a single fiber fineness of 0.5 dtex or less, metal foil, metal-deposited film, and photographic film, cellulose fiber, and hydrazine compound. Functions such as heat-absorbing acrylic fibers, carbon fibers, graphite fibers, aramid fibers, glass fibers, etc., heat-resistant fibers such as hemp fibers, metal fibers, metal, ceramics, and other highly heat-conductive fibers It is advisable to mix sexual fibers.

The present invention intends to use plastic monofilament yarn instead of fibrous plant filaments that form leaf stems of straw, rattan, camellia, cocoon leaf shaft, sisal hemp shaft, pineapple leaf shaft and other plants. The yarn 11 is not of a circular cross-sectional shape, but is preferably a thick monofilament having a flat circular cross-sectional shape similar to those fibrous plant filaments and having a fineness exceeding 1000 dtex.
As described above, the surface of a thick flat monofilament having a fineness exceeding 1000 dtex is smooth. However, in the present invention, the multifilament yarn 12 is applied to the shaft yarn 11, so that the surface of the plant filament such as rattan is used. A surface material excellent in durability can be obtained having functionalities such as slip resistance, fire resistance, moisture absorption, and light resistance equivalent to those of the material.
In particular, when the axial yarn 11 having a fineness of 2000 dtex is used, it is used for the weft, and the weft insertion warp knitted fabric (FIGS. 1 and 4), the weft insertion weft knitted fabric (FIG. 2), or the kneading The surface material 10 may be configured as a woven fabric (FIG. 1).

  Thus, according to the present invention, not only does it have breathability and does not give a feeling of stuffiness, but also has moderate hygroscopicity, is easy to adjust to the bare skin, has a good touch, and directly melts and breaks when touching the fire of tobacco. Fire resistance, anti-slip property, non-slip, stable limbs during use, no fatigue, dyeing and printing, various finishes, deodorant, Excellent functionality such as antibacterial, antifungal, insect repellent, aromatic, antistatic, radiant, luminous and phosphorescent, etc. New in design, especially suitable for the surface material of summer support equipment A woven or knitted fabric is obtained.
