Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a high-density fabric. More specifically, the present invention provides a stretchable high-density woven fabric composed of polytrimethylene terephthalate fiber multifilament yarn.

[0002]

2. Description of the Related Art Hitherto, high-density woven fabrics using a polyamide-based multifilament yarn or a polyester-based multifilament yarn have been known and widely used in winter clothing for down jackets and sports clothing for blousons and windbreakers. Have been. However, since high-density woven fabrics generally have little elongation, the movement of the body during exercise is hindered, or a feeling of oppression is felt, and free movement is not possible. Further, because of the high-density woven fabric, the hardness of the fabric is further increased by water repellent processing or resin processing for imparting water resistance or the like, and as a result, the cloth is hard and bulky for exercise and body movement. Due to problems such as hindered movement, rubbing noise when the fabrics are in contact with each other due to the hardness of the fabric, and discomfort. There is a demand for softening of texture and texture.

A typical example is disclosed in Japanese Patent Application Laid-Open No. 9-17017.
No. 5 proposes a woven fabric having improved windproofness and water pressure resistance by using a superfine multifilament yarn having a round cross section of a single yarn fineness of 0.5 denier or less and having a sum of cover factors of warp and weft of 2200 or more. Have been. However, with this high-density fabric, good water pressure resistance can be obtained, but there is almost no stretchability (2% in terms of stretch ratio described later).
Before and after). Also, JP-A-62-238842 discloses that
A woven fabric comprising a mixed yarn of a 2.08 denier W-shaped irregular cross-section multifilament yarn and a 0.28 denier round cross section ultrafine multifilament yarn has been proposed. However, this fabric has improved water pressure resistance due to the ultrafine filament yarn, but has little stretchability. On the other hand, as a fabric for obtaining stretchability, for example, as a yarn constituting the fabric, there is a method using a polyurethane-based elastic fiber excellent in elasticity (including a twisted yarn with another yarn and a covering yarn). This fabric is thick, coarse and hard, and has coarse eyes, so that water resistance cannot be obtained.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a high-density woven fabric which has a soft feel and a rubbing sound with a stretch property and which is excellent in wearing comfort.

[0005]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, the present invention has been attained by using a polytrimethylene terephthalate fiber multifilament yarn and applying a special treatment. The present invention has been completed and the present invention has been completed. That is, the present invention is a high-density woven fabric having a cover factor of 1700 to 2400, wherein the woven fabric has a stretchability of 5 to 20% in a warp direction or a weft direction and has at least a stretchability. A stretchable high-density woven fabric characterized in that the yarns in the direction are constituted by polytrimethylene terephthalate fiber multifilament yarns. Here, the woven fabric is most preferably a plain woven fabric, but may be a twill woven fabric, a patterned woven fabric, or a multiplex woven fabric.

Hereinafter, the present invention will be described in detail. In the present invention, the polytrimethylene terephthalate fiber refers to a polyester fiber having a trimethylene terephthalate unit as a main repeating unit, and the trimethylene terephthalate unit has about 50 mol% or more, preferably 70 mol% or more, and more preferably 80 mol%. Above, more preferably 90 mol% or more. Therefore, the total amount of the other acid component and / or glycol component as the third component is about 5%.
0 mol% or less, preferably 30 mol% or less, and more preferably 20 mol% or less.
It includes polytrimethylene terephthalate contained in an amount of at most 10 mol%, more preferably at most 10 mol%.

[0007] Polytrimethylene terephthalate is produced by polycondensing terephthalic acid or a functional derivative thereof with trimethylene glycol or a functional derivative thereof in the presence of a catalyst under appropriate reaction conditions. In this production process, an appropriate one or two or more third components may be added to form a copolymerized polyester, or
Polytrimethylene terephthalate and other polyesters other than polytrimethylene terephthalate, such as polyester and nylon, and polytrimethylene terephthalate may be separately produced and then blended or composite-spun (sheath core, side-by-side, etc.).

The third component to be added includes aliphatic dicarboxylic acids (oxalic acid, adipic acid, etc.), alicyclic dicarboxylic acids (cyclohexane dicarboxylic acid, etc.), aromatic dicarboxylic acids (isophthalic acid, sodium sulfoisophthalic acid, etc.). ), Aliphatic glycols (ethylene glycol, 1,2
-Propylene glycol, tetramethylene glycol, etc.), alicyclic glycols (cyclohexane dimethanol, etc.), aliphatic glycols containing aromatics (1,4-bis (β-hydroxyethoxy) benzene, etc.), polyether glycols (polyethylene glycol) , Polypropylene glycol and the like), aliphatic oxycarboxylic acids (such as ω-oxycaproic acid), and aromatic oxycarboxylic acids (such as P-oxybenzoic acid).

Compounds having one or more ester-forming functional groups (such as benzoic acid or glycerin) can also be used within a range where the polymer is substantially linear. Further, matting agents such as titanium dioxide, stabilizers such as phosphoric acid, ultraviolet absorbers such as hydroxybenzophenone derivatives, crystallization nucleating agents such as talc, lubricating agents such as aerosil, antioxidants such as hindered phenol derivatives, and the like. Flame retardants, antistatic agents, pigments, fluorescent brighteners, infrared absorbers, defoamers, and the like may be included.

In the present invention, a method of spinning polytrimethylene terephthalate fiber is to obtain an undrawn yarn at a winding speed of about 1500 m / min and then to twist about 2-3.5 times, a spinning-drawing step. And a high-speed spinning method (spin take-up method) with a winding speed of 5000 m / min or more.
Further, the form of the fiber is a multifilament yarn, which may be uniform or thick in the length direction, and may have a round, triangular, L, T, Y, W Type,
Polygonal types such as an eight-leaf type, a flat type, a dog bone type, etc., a multi-leaf type, a hollow type and an irregular type may be used.

[0011] The yarn fineness is generally 30 to 150 denier, preferably 50 to 10 denier used as a high-density fabric.
The denier is preferably 0 denier and the fineness of the single yarn is 0.1 to 5 denier, preferably 0.5 to 3 denier. If the yarn fineness is less than 30 denier, sufficient strength may not be obtained when the woven fabric is used, and if it exceeds 150 denier, the woven fabric tends to be thick and coarse. If the single yarn fineness is less than 0.1 denier, weaving becomes difficult, and if it exceeds 5 denier, the texture tends to be coarse and hard. Further, as the form of the yarn, a multifilament raw yarn (including an ultrafine yarn),
There are sweet twisted yarn to strong twisted yarn, mixed yarn, false twisted yarn (including drawn false twisted yarn of POY), air jet processed yarn and the like, and any yarn may be used.

It is to be noted that other fibers are usually entangled and mixed (different shrinkage mixed yarns with high shrinkage yarns), intertwisted, and composite temporary yarns within a range of not more than 30% by weight without impairing the object of the present invention. Twist (elongation difference false twist, etc.) may be mixed by means such as two-feed air injection processing. The fibers to be mixed may be any fibers, but synthetic fibers such as polyester fibers, polyamide fibers, polyacrylonitrile fibers, polyvinyl fibers, and polypropylene fibers can be used. In the present invention,
Although the above-mentioned polytrimethylene terephthalate fiber yarn is used for the weft and the warp of the woven fabric, or the weft or the warp,
The other fibers to be interwoven may be any fibers. Preferably, synthetic fibers such as polyester fibers, polyamide fibers, polyacrylonitrile fibers, polyvinyl fibers, and polypropylene fibers are used.

The feature of the present invention is that the stretch ratio in the direction using the polytrimethylene terephthalate fiber yarn is 5%.
-20%, preferably 7-17%.
If the stretch rate is less than 5%, the movement of the body during exercise may be impeded or pressure may be felt, making free movement impossible and unpleasant. Bending becomes too large, roughness on the fabric surface,
It is not preferable because the thickness is increased and the water resistance is decreased.
In addition, the stretch rate mentioned here means elongation (%) when stretched under a stress of 500 g / cm using KES-FB1 manufactured by Kato Tech.

In the present invention, as a method for obtaining a stretch property, a woven fabric (raw machine) made of polytrimethylene terephthalate fiber yarn is subjected to a high shrinkage treatment with hot water, moist heat, dry heat or the like to obtain polytrimethylene terephthalate. This is to impart a fine bend (that is, a woven crimp) to the fiber yarn. That is, it is obtained by increasing the density difference between the original woven fabric (raw machine) density and the finished woven fabric density of the final product. By causing tissue shrinkage in addition to shrinkage, fine bends (woven crimps) are given in the warp or weft direction to give desired stretchability.
Polytrimethylene terephthalate fiber has a characteristic that it is extremely flexible because the fiber has a smaller Young's modulus than polyethylene terephthalate fiber or polybutylene terephthalate fiber, which is a typical example of a conventional polyester fiber. Softness is a major factor in causing tissue shrinkage. By using this very flexible soft polytrimethylene terephthalate fiber yarn, it is possible to produce a greige fabric in a form in which the weft is wound around the warp or the warp is sufficiently wound around the weft, and heat treatment is performed to further increase the form. By doing so, a woven fabric having a form in which the weft is wrapped around the warp or the warp wrapped around the weft, that is, a form in which the weft or the warp is crimped, can exhibit high elongation due to the expansion and contraction of the crimp.

The high shrinkage treatment is designed to have a density design that is 10 to 40% higher than the original fabric (green fabric) density. If the density increase is less than 10%, sufficient stretchability cannot be obtained,
If it exceeds 40%, wrinkles are formed on the woven fabric, or large curving occurs, thereby deteriorating the quality. As a more preferable method for imparting the stretch property, in view of productivity, appearance quality, performance, etc., the warp density is designed to be coarse, and a woven fabric (raw machine) using a polytrimethylene terephthalate fiber yarn at least for the weft is used. In the direction, the width is increased (high shrinkage treatment) by heat treatment before or after scouring under almost tension, to impart stretchability in the weft direction. By designing the warp roughly and heat-treating it under tension, the insertion ratio is improved, and a material having a substantially large stretch ratio can be obtained.

In order to impart a stretch property in the warp direction, at least a woven fabric (raw machine) using polytrimethylene terephthalate fiber yarn as a warp thread is driven in by a heat treatment before or after scouring with almost tension in the weft direction. (High shrinkage treatment). As the heat treatment conditions, in the case of the dry heat treatment, using a tenter for holding the weave ears, a short loop net processing of a conveyor system without holding the weave ears (free), a drum treatment, or the like, in order to obtain a desired stretch. It is preferable to use a pin tenter method that can control the dimensions in the longitudinal and weft directions. The heat treatment temperature is 150 to 210
If the temperature is lower than 150 ° C., sufficient shrinkage treatment cannot be performed, and desired stretchability cannot be obtained. If the temperature exceeds 210 ° C., the strength decreases and the texture becomes coarse and hard. In the case of hot water treatment, the treatment is preferably performed at 100 to 140 ° C. using a device such as a jet dyeing machine having a large kneading effect. If the temperature is lower than 100 ° C., sufficient shrinkage treatment cannot be performed.
Desired stretchability cannot be obtained. At 140 ° C. or higher, a special device is required, and there is a problem in productivity.

In the case of the hot water treatment, if the greige fabric or the woven fabric after the scouring is directly subjected to the above-mentioned hot water treatment, a large wrinkle or the like is generated due to a rapid shrinkage of the yarn or the structure. Prior to this, it is preferable to perform a light thermal preset at 150 ° C. or less. In addition, scouring in the present invention is a step of removing spinning oil, warp sizing agent, and the like adhering to the woven fabric, and the treatment liquid used in this scouring contains water or a surfactant and an alkali. Aqueous solution is good. The method for performing the scouring is not limited, but an open soap type continuous scouring machine, a liquid flow type dyeing machine, a bath-suspended continuous scouring machine, a wins dyeing machine, a softa scouring machine generally used in the scouring of textiles The treatment is preferably performed at a temperature of 100 ° C. or lower using a method such as the above. After finishing the heat treatment and scouring,
Performs the dyeing and finishing steps, which are common processing steps. When softening the hand, alkali weight reduction processing may be performed before dyeing.

Further, in the present invention, the cover factor of the woven fabric is set slightly lower than the cover factor of the high-density woven fabric. This is because high-density woven fabrics are generally finished by high-density weaving in the weaving stage in the direction of minimizing voids between woven yarns in order to improve water resistance. This is because there is almost no void between the yarns because the yarns overlap each other. In the present invention, in order to obtain desired stretchability, good water resistance and soft texture, the covering factor of the woven fabric is 17
00 to 2400, preferably 1800 to 2200.

The cover factor referred to here is given by the following equation, where the number of warp or weft yarns of the woven fabric per 2.54 cm of width is the respective yarn density. Cover factor = (warp density x √ warp denier) +
(Weft density × √denier of weft) If the cover factor is less than 1700, sufficient water resistance cannot be obtained, and if the cover factor exceeds 2400, the desired stretchability cannot be obtained and the texture becomes coarse and hard. .

In the present invention, in addition to the low Young's modulus softness and stretchability of the polytrimethylene terephthalate fiber yarn, the effect of imparting fine bends (woven crimps) and a moderate cover, while being a high-density woven fabric. Depending on the factor, a softer and noiseless woven fabric having desired stretchability and water resistance and excellent in wearing comfort that cannot be obtained conventionally can be obtained. The wearing comfort in the present invention refers to a state in which the fabric follows the movement of the body at the time of exercise, the movement of the body is not hindered, and the body can move lightly and freely without feeling any oppression, and the ruggedness of the fabric , A comfortable wearing feeling without feeling the rubbing sound between the fabrics.

The high-density woven fabric of the present invention thus obtained is excellent in down-proofing property (performance for preventing the down material filled in the cold-protective garment from leaking out to the cloth surface) from the above-mentioned performance aspect, and is excellent. Because of its excellent air permeability, it is possible to obtain a winter jacket that has excellent wearing comfort as a winter jacket. In addition, in the present invention, by performing a water repellent treatment and optionally a blinding process on the high-density fabric obtained in this way, a water-repellent, water-resistant, non-coated waterproof fabric having good water resistance while maintaining the above performance is obtained. As a result, it is possible to obtain a product having excellent wearing comfort such as for a raincoat or a sports windbreaker.

In the processing of the waterproof fabric, a silicon-based, fluorine-based, wax-based, zirconium salt-based, ethyleneurea-based, methylolamide-based, pyridinium salt-based, metal soap, or the like is used as a water repellent. Although not particularly limited, a silicon-based or fluorine-based water repellent is preferably excellent in water repellency and durability. In addition, you may add a crosslinking agent, a catalyst, resin, etc. to the said water repellent as needed. This water repellent can be processed by a method such as spraying, dipping squeezing liquid, or kiss roll. In addition, the blinding process is to press the woven fabric after the water repellent treatment process, thereby smoothing the woven fabric surface and reducing the fiber gap to further improve the water resistance. This has the effect of making it more flexible.

In this press working method, working is performed by pressing between two pairs of rolls, belts, flat plates, or the like at normal temperature or high temperature. Heating roll, the other is made of metal,
Hard low-temperature paper rolls made of resin or rubber,
It is preferable to use a general calendering machine including a medium-hard and low-temperature roll such as felt. As the pressing conditions, the heating roll is set to 120 to 200 ° C., preferably 140 ° C.
To 180 ° C, and the low-temperature roll is 120 ° C or less. If the temperature of the heating roll is lower than 120 ° C., the blinding effect is diminished and sufficient water resistance cannot be obtained. If the temperature exceeds 200 ° C., the hand becomes hard and paper-like. On the other hand, the low temperature roll is 120 ° C
Beyond, the texture becomes hard and paper-like. Also,
The pressure is preferably a linear pressure of 100 to 400 kg / cm. If the linear pressure is less than 100 kg / cm, the blinding effect is small and sufficient water resistance cannot be obtained.
Beyond, the texture becomes hard and paper-like.

In the present invention, by coating or laminating a resin on the high-density woven fabric or waterproof woven fabric thus obtained, it is possible to obtain a highly water-resistant, moisture-permeable and waterproof woven fabric in addition to the above-mentioned properties. As a result, it is possible to obtain a product excellent in wearing comfort for use in sports clothing under severe environments. The processing of this moisture-permeable / waterproof fabric is exemplified by resins such as polyurethane-based polymers, polyacryl-based polymers, polyamide-based polymers, polyester-based polymers, polyvinyl chloride-based polymers, and polyfluorinated polymers. But
Preferably, a polyurethane-based polymer is used from the viewpoint of the texture. As the film structure, either a microporous film or a nonporous film can be used.

The non-porous film is formed by adding -SO ₃ H,-
SO ₃ M (M: alkali metal or —NH ₄ ), —COO
_{M, -COOH, -NH 2, -CN} , -OH, -CON
Any polymer having a hydrophilic group such as H ₂ may be used. When the polymer containing the hydrophilic group is formed into a film by dry coagulation, moisture permeability is obtained by the hydrophilic group, and a non-porous film is formed. Therefore, a highly water-resistant fabric can be obtained. Further, in order to make the polymer film into a microporous film, a method of adding a foaming agent to the polymer and foaming after coagulation, a method of adding fine particles to the polymer and dissolving and extracting the fine particles after coagulation, and dissolving the polymer There is a wet coagulation method of forming a film by mixing a polymer solution and a solvent that can be uniformly mixed with a solvent without dissolving the polymer, and then extracting both solvents to form microporous. The wet coagulation method is preferred from the viewpoints of uniformity, stability, membrane and microporosity.

The method of coating the resin is not particularly limited. Generally, coating is performed using a floating knife coater, knife over roll coater, reverse roll coater, roll doctor coater, gravure roll coater, kiss roll coater, nip roll coater, or the like. can do. The method of laminating the resin is to use a resin film (film),
It is bonded by heating with an adhesive previously applied to the fabric. As an adhesive for adhering the woven fabric and the film, a polyurethane polymer, a polyacrylic polymer, a polyamide polymer, a polyester polymer, a polyvinyl chloride polymer, a polyvinyl acetate polymer, or the like can be used. However, a polyurethane-based polymer, a polyamide-based polymer, and a polyester-based polymer are preferred.

The method of applying the adhesive includes a general floating knife coater, knife over roll coater,
There is a full-surface adhesion method that applies to the entire surface of the fabric using a reverse roll coater, a roll doctor coater, a gravure roll coater, a kiss roll coater, a nip roll coater, etc. Instead, it can be selected and used as appropriate. The film thickness in the coating and laminating is 5 to 20 μm from the textured surface. If the film thickness is less than 5 μm, it is difficult to obtain a uniform film thickness and sufficient water resistance cannot be obtained. The texture is too hard to be too large.
