Description

  The present invention is used for sportswear and other outerwear cuffs, heels, hem parts, trouser hems, wrist parts such as gloves, supporters, etc. The present invention relates to a light-reflective warp knitted fabric having stretchability.

  In recent years, when light from a headlight such as an automobile hits when walking at night, road construction, etc., it reflects the light reflective thread (including a light reflective thread, including a thin light reflective film) Knitted fabric that is partially inserted) is the cuffs of outerwear such as sportswear and other outerwear including work clothes, wrists such as heels, hems, trousers, gloves, etc. Used for parts, supporters, etc., it has been applied to improve wearer safety.

  These conventionally proposed knitted fabrics have a problem that they are not stretched and are difficult to apply to a knitted fabric in a region where stretchability is required.

  Therefore, in recent years, a knitted fabric described as having stretchability has also been proposed (see Patent Documents 1 and 2 below).

  However, knitted fabrics are generally known to be stretchable compared to woven fabrics because the stitches of the knitted structure are generally stretched when pulled, but these knitted fabrics described in these patent documents are knitted compared to woven fabrics. The original knitted fabric with an extent that the stitch of the tissue is stretched has only the elasticity that the knitted fabric has, and the light reflective yarn is not stretchable. Since the stretchability is hindered, for example, a light-reflective warp knitted fabric having a large stretchability that extends about 150% or 200% of the original length in the length direction of the light-reflective yarn has not been obtained.

  Sports wear, work clothes, wrist parts such as gloves, supporters and the like are required to have a relatively large stretchability, and therefore it is preferable that the stretchability is large.

  Hereinafter, in order to facilitate understanding of the present invention, the present invention will be described with reference to specific embodiments. However, the present invention is not limited to these specific embodiments. . In the warp knitted fabric of the present invention, the course direction means the knitting direction (the direction in which the warp knitted fabric is knitted and discharged from the warp knitting machine, the so-called warp knitting, as the meaning of ordinary terms in the industry. The warp direction means the direction perpendicular to the course direction and the transverse direction of the warp knitted fabric.

  FIG. 1 shows an actual knitting structure diagram of a light-reflective warp knitted fabric having elasticity according to an embodiment of the present invention as viewed from the loop side (also referred to as a knitted back or a technical face). 2 is a knitting structure diagram of the light-reflective warp knitted fabric having elasticity shown in FIG. 1 shown from the movement of the guide bar, and is a knitting structure diagram showing the knitting structure using another display format. 1 and 2 show the same knitting structure. FIG. 3 is a practical disassembled organization chart in which the yarn structures used in the knitting structure shown in FIG. 1 are individually arranged for each yarn.

  In this embodiment, the thread (A) constituting the loop structure is indicated by L1. L1 is made of inelastic yarn and is a full packing of all wales. In this example, L1 is a chain stitch structure, and is represented by 0-2 / 2-0 / 0-2 / 2-0 when represented by a chain number. As shown in this embodiment, the chain structure is preferable as the loop structure. However, if the loop structure is used, the function of the present invention such as the denby structure shown in FIG. 8 or the cord structure shown in FIG. As long as is exhibited, other loop structures may be used.

  In this embodiment, the insertion yarns (B1) and (B2) constituting the insertion tissue are examples using two types of L5 and L3. In this embodiment, L5 is a so-called inter-needle insertion tissue in which two wales are inserted alternately at an angle, and when indicated by a chain number, 0-0 / 4-4 / 0- 0 / 4-4 insertion tissue. Although this structure is preferable, as long as the function of the warp knitted fabric of the present invention is not hindered, for example, an inserted structure of 0-0 / 6-6 / 0-0 / 6-6 or 0-0 / 4-4 / 0- Other insertion tissues such as 0 / 6-6 may be used.

  In this embodiment, L3 is further inserted as an insertion thread that constitutes the insertion tissue. In this embodiment, L3 is a so-called inter-needle insertion tissue that is inserted diagonally and alternately between three wales. When indicated by a chain number, L6 is 6-6 / 0-0 / 6. It becomes an insertion tissue of −6 / 0-0. Although this structure is preferable, as long as it does not hinder the function of the warp knitted fabric of the present invention, for example, 6-6 / 0-0 / 4-4 / 0-0 or 4-4 / 0-0 / 4/4 / 0- Other insertion tissues such as zero insertion tissue may be used.

  In particular, it is preferable that L3 and L5 extend obliquely in opposite directions in each course as in the modes shown in FIGS. 1 to 3. The insertion yarns (B1) and (B2) are expressed as “two types of insertion yarns (B1) and (B2) whose swing directions are opposite to each other in each course”. In this way, the insertion yarns (B1) and (B2) can be used independently by using two types of insertion yarns (B1) and (B2) in which the swing directions are opposite to each other in each course. Compared to the case, the warp knitted fabric obtained is not skewed, and a stable fabric can be obtained. In the embodiment shown in FIG. 1, in this example, L5 is a so-called inter-needle insertion tissue in which two wales are alternately inserted diagonally, and L3 is diagonally between three wales. Although the insertion tissue of so-called three-needle insertion inserted alternately is used, for example, L5 and L3 may be inserted between the same number of needles, or limited to two-needle insertion and three-needle insertion. However, the embodiment shown in FIG. 1 is preferable in terms of slightly increasing the thickness of the warp knitted fabric obtained because one of them is inserted between three stitches. However, if it is made too thick, it tends to decrease in terms of stretchability, so a design that makes the thickness extremely thick is not very suitable.

  In addition, L3 and L5 are also made of inelastic yarns, and all are full wales. If necessary, at least one of L3 and L5 may be a loop structure, but it is preferable to use an insertion structure because the elasticity tends to decrease.

  In this way, one or a plurality of light-reflective yarns (C) are inserted in the course direction (longitudinal direction) at a desired location of the knitted structure constituted by L1, L5, and L3. In the embodiment shown in FIGS. 1 to 5, one L4 is inserted as a light-reflective yarn (C) in the course direction at a predetermined wale. When indicated by a chain number, it is indicated by an inserted tissue of 0-0 / 0-0 / 0-0 / 0-0. As described above, a plurality of light-reflective threads (C) to be inserted may be inserted, and the light-reflective thread (C) may be inserted in a plurality of arbitrary locations in the course direction.

  Here, of the insertion yarns (B1) and (B2) [L5 and L3 in this embodiment] constituting the insertion tissue, one of the insertion yarns L5a that repeatedly traverses the light reflective yarn L4 is an inelastic yarn. (In this embodiment example, a transparent monofilament yarn) and a thermal bonding yarn alignment yarn (D1), and the non-elastic yarn (in this embodiment example, a transparent monofilament yarn) is light-reflective yarn by the thermal bonding yarn. It is bonded to the light reflecting surface side of the light reflecting yarn L4 at an intersection crossing L4. When the light reflecting surface of the light reflecting yarn is a light reflecting yarn formed on both sides of the light reflecting yarn or the entire surface of the yarn, the inelastic yarns of (D1) and (D2) are bonded. The surface of the light-reflective yarn may be bonded to any surface of the light-reflective yarn as long as (D1) and (D2) are bonded to the opposite surfaces of the light-reflective yarn. FIG. 4 shows the actual organization chart viewed from the loop side (back of the knitting) displaying only the light-reflective yarn L4 and one of the insertion yarns L5a that repeatedly crosses this (for ease of understanding, in FIG. Not shown in the drawing, L3 is also shown in FIG. 5, FIG. 1, FIG. L5a includes an inelastic yarn (transparent monofilament yarn in this embodiment) and a thermal bonding yarn alignment yarn (D1), and the inelastic yarn (transparent monofilament yarn in this embodiment) is the thermal bonding yarn. Is bonded to the light reflective yarn L4 at the intersection 1 crossing the light reflective yarn L4. The other insertion thread L5 (for ease of understanding in FIG. 4, L3 is not shown, so refer to the description of FIG. 5 for L3) is made of a normal inelastic thread that does not include a thermal bonding thread or the like. .

  Furthermore, in a state similar to the above in which one light reflective yarn L4 is inserted, a practical partial organization chart viewed from the loop side (knitting back) displaying only the light reflective yarn L4 and the insertion yarns L5 and L3. This is shown in FIG. The insertion yarns that repeatedly traverse one light-reflective yarn L4 are only two of L3a and L3b in the insertion yarn L3 and L5a in L5. Here, the insertion yarn 3 that repeatedly traverses these light-reflective yarns L4. Among the books, one L5a is an inelastic yarn (transparent monofilament yarn in this embodiment) and a thermal bonding yarn alignment yarn (D1), and the insertion yarn L3 has at least one of L3a and L3b ( In this example, only L3a is used from the viewpoint of cost, but both L3a and L3b may be used.Of course, L3b alone may be used as the alignment yarn (D2) of inelastic yarn and thermal bonding yarn, and the insertion yarn (B2 ) Of the non-elastic yarn is bonded to the light-reflective yarn on the side opposite to (D1) at the intersection of the heat-bonded yarn and the light-reflective yarn. In this case, L5a crosses the front side of the light reflective yarn L4, L3a and L3b cross the back side of the light reflective yarn L4, and L5a, L3a, and L3b sandwich the light reflective yarn L4 from the front and back sides. . In this way, in order to sandwich the light reflective yarn L4 between the insertion yarns L5 and L3, the guide bars of the respective light reflective yarns L4 such as L3, L4, and L5 are set to L3 and L5. It is sufficient to set the position between the two guide bars and knit. The other insertion yarns L3 and L5 are made of ordinary inelastic yarns that do not include thermal bonding yarns, except for the portions using the inelastic yarns and the thermal bonding yarns (D1) and (D2). Become.

  Only the light-reflective yarns L4a and L4b in the case of two light-reflective yarns L4 and one of the insertion yarns L5a and L5b that repeatedly traverse each of these light-reflective yarns L4a and L4b are displayed. The actual knitting organization diagram viewed from the loop side (back of the knitting) is shown in FIG. 6 (L3 is not shown in FIG. 6 for easy understanding). L5a and L5b are composed of an inelastic yarn (transparent monofilament yarn in this embodiment) and a thermal bonding yarn alignment yarn (D1), and the inelastic yarn (transparent monofilament yarn in this embodiment) is the thermal yarn. The light-reflective yarns L4 (L4a, L4b) are bonded to the light-reflecting surface side of the light-reflective yarns L4 (L4a, L4b) at the intersection 1 that crosses the light-reflective yarns L4 (L4a, L4b). The other insertion thread L5 is made of a normal inelastic thread that does not include a thermal bonding thread or the like. That is, one of the insertion yarns L5a and L5b repeatedly traversing each of the plurality (two in this example) of the light reflecting yarns L4a and L4b is an inelastic yarn (in this embodiment, a transparent monofilament yarn). ) And a thermal bonding yarn alignment yarn (D1), and the transparent monofilament yarn crosses the light-reflecting yarn with the heat-bonding yarn at the respective intersections 1 and 1, and the light of the respective light-reflecting yarns L4a and L4b. Each of them is bonded to the reflecting surface side. The other insertion thread L5 is made of a normal inelastic thread that does not include a thermal bonding thread or the like.

  6 is the same as that shown in FIG. 6 except that the insertion positions of the two light-reflective yarns L4a and L4b are slightly different, and the loop side displaying only the light-reflective yarn L4 and the insertion yarns L5 and L3. Fig. 7 shows the actual partial organization chart as seen from the back of the book. The insertion yarns that repeatedly traverse each of the two light reflective yarns L4a and L4b are L3a and L3b for the light reflective yarn L4a and L3b and L3c for the light reflective yarn L4b of the insertion yarn L3. In L5, only L5a is applied to the light reflective yarn L4a, and only L5b is applied to the light reflective yarn L4b. Here, some of these light reflective yarns L4a and L4b are repeatedly traversed. For each of the light-reflective yarns L4a and L4b, one of L5a and L5b is an inelastic yarn (transparent monofilament yarn in this embodiment) and a thermal bonding yarn alignment yarn (D1). It is what. In this case, L5a traverses the reflective surface side of the light reflective yarn L4a, and similarly L5b traverses the reflective surface side of the light reflective yarn L4b, and insertion yarns L3a, L3b, crossing the light reflective yarns L4a, L4b, L3c crosses the back side [the side opposite to (D1)] of the light reflective yarns L4a and L4b, and the light reflective yarns L4a and L4b are sandwiched from the front and back by L5a and L5b and L3a, L3b and L3c, respectively. In this embodiment, at least one of the insertion yarns L3a, L3b, L3c crossing the light-reflective yarns L4a, L4b (in this example, only L3b is used in terms of cost, but two of L3a and L3c, Two of L3a and L3b, two of L3b and L3c, or three of L3a, L3b, and L3c may be used), and the insertion yarn (D2) is made using a non-elastic yarn and a thermal bonding yarn (D2). of The inelastic yarn is bonded to the light-reflective yarn on the side opposite to (D1) at the intersection point where the heat-bonded yarn crosses the light-reflective yarn. The other insertion yarns L3 and L5 are made of ordinary inelastic yarns that do not include thermal bonding yarns, except for the portions using the inelastic yarns and the thermal bonding yarns (D1) and (D2). Become.

  Similarly, three or more light reflective yarns may be used.

  Further, another important requirement in the present invention is that the elastic yarn (E1) has a structure composed of alternating repetition of one or more loop tissue units (e1) and one or more inserted tissue units (e2) in the course direction. ) Or the alternating repetition of the single or plural loop organizational units (e1) and the single or plural loop organizational units (e1) in the course direction without floating between the single or plural loop organizational units (e1). That is, the elastic yarn (E2) having the structure is knitted in all the wales.

  In the embodiment shown in FIGS. 1 to 3, an elastic yarn having a structure composed of an alternating repetition of a chain stitch structure which is one of the loop structure units continuous for two courses in the course direction and an insertion tissue unit continuous for two courses ( E1) L2 (2-0 / 0-2 / 2-2 / 0-0 in terms of chain number) is knitted in all wales. However, in FIG. 1, if the elastic yarn L2 is written in all wales, the drawing becomes complicated and difficult to understand. Therefore, only two wales are shown, and illustration is omitted in the other wales. Due to the stretching force of the elastic yarn (E) L2, a light-reflective warp knitted fabric having stretchability in which ridges and grooves whose longitudinal direction is parallel to the wale direction is alternately formed is formed.

  Instead of the elastic yarn (E1), the single or plural loop structural units (e1) and the single or plural loop structural units (e1) are floated and connected in the course direction without insertion. You may use the elastic thread | yarn (E2) of the structure | tissue which consists of alternating repetition of (e3). FIG. 10 is an actual disassembled organization chart in which the elastic yarn (E1) is replaced with the elastic yarn (E2) in FIG. Indicated. When the elastic yarn (E2) L2 ′ shown in FIG. 10 is represented by a chain number, it is 2-0 / 0-2 / 2-2 / 2-2. Except for L2, L1, L3, L4 and L5 are the same as in FIG. 3 in this embodiment.

  The knitting structure of the elastic yarn (E) belongs to the elastic yarn (E1) shown in FIGS. 1 to 3, and the elastic yarn is integrated into the warp knitted fabric. However, it is preferable that the elastic yarn (E2) such as the elastic yarn L2 ′ shown in FIG. 10 is part of the elastic yarn from the back side of the knitted fabric (in FIG. 15 described later). Except that the elastic yarn 2 passing through the back side that appears in the portion connecting the groove 4 and the groove 4 of the warp knitted fabric to be described (protrusions 4 ′ and 4 ′ convex on the back side on the back side reference) is visible, This is one of the preferred embodiments because the function almost the same as that of the elastic yarn (E1) is exhibited.

  As long as the elastic yarn (E) does not hinder the object of the present invention, the elastic yarn (E) may have any structure as long as it is composed of alternating repetition of one or more loop tissue units and one or more inserted tissue units in the course direction. 11 or a structure in which loop tissue units and insertion tissue units are alternately repeated as shown in FIG. The elastic yarn shown in FIG. 11 is an elastic yarn of the type belonging to (E1), and its knitting structure is a repetition of the structure of 2-0 / 2-4 / 0-0 / 4-4 when represented by a chain number. The elastic yarn shown in No. 12 is also an elastic yarn of the type belonging to (E1), and its knitting structure is a repetition of the structure of 2-0 / 2-4 / 2-2 / 2-2 when expressed by a chain number.

  Note that “from the repetition of the single or plural loop organizational units (e1) and the organizational unit (e3) in which the single or plural loop organizational units (e1) are floated and connected without insertion in the course direction. The term “elastic yarn (E2) of the structure” “is floating and connected without insertion” may also be referred to as “to play” in industry terms. The portion of “(e1) is a structure unit (e3) that floats and connects with each other without insertion” is not inserted into the loop, and is not integrated into the warp knitted fabric. Part of the warp knitted fabric described in FIG. 15 appears on the back side of the warp knitted fabric at the portion connecting the grooves 4 and 4 [protrusions 4 'and 4' on the back side on the back side reference (elastic yarn). 2) It becomes a structure.

  Generally, when the knitted fabric of the present invention is viewed from the surface side, when attention is paid to the elastic yarn (E1), the heel portion is usually the portion of the inserted tissue unit (e2) of the elastic yarn (E1), and the groove portion Is a portion of the loop structure unit (e1) of the elastic yarn (E1), so that the number of units in which the loop structure unit (e1) of the elastic yarn (E1) is continuous and the number of units in which the insertion structure unit (e2) is continuous By adjusting the number of units, the width of the flange portion and the width of the groove portion can be adjusted to a desired width. Usually, the larger the number of units in which the loop structure unit (e1) of the elastic yarn (E1) continues, the wider the width of the groove portion, and the larger the number of units in which the inserted tissue unit (e2) continues, the wider the width of the heel portion. Become. Conversely, the width of each becomes smaller.

  Similarly, when the structure of the elastic yarn (E2) is used, the structure unit (e3) of the elastic yarn (E2) usually floats without insertion between the single or plural loop structure units (e1) as described above. In other words, because it is “playing”, it is structured so that it does not enter the heel portion and does not enter the heel portion as in the inserted tissue unit (e2), and the groove portion is a loop structure unit of the elastic yarn (E2) ( The portion of the structural unit (e3) of the elastic yarn (E2) is the groove 4 and groove 4 of the warp knitted fabric described later with reference to FIG. In this structure, the part (e3) appears on the back side of the warp knitted fabric at the part connecting the convex parts 4 ′ and 4 ′]. Also in this case, there are structural units (e3) in which the loop structural units (e1) of the elastic yarn (E2) and the single or plural loop structural units (e1) are floated and connected without insertion. By adjusting the number of units of the continuous units, the width of the flange portion and the width of the groove portion can be adjusted to a desired width. Usually, the width of the groove portion becomes wider as the number of continuous units of the loop structure unit (e1) of the elastic yarn (E2) becomes larger, and the width of the heel portion becomes wider as the number of units of continuous structure unit (e3) becomes larger. . Conversely, the width of each becomes smaller.

  As described above, the width of the flange portion and the width of the groove portion can be appropriately set according to demand. Although not particularly limited, the elastic yarn (E) is composed of a loop structure unit of 2 to 4 courses in the course direction and an insertion structure unit of 2 to 4 courses, or a loop structure of 2 to 4 courses in the course direction. Adjusting within the range of organizational units that are floating and connected without inserting the unit 2 to 4 courses in succession, the cuffs, heels, hems, and trousers of sportswear, other outerwear including work clothes, etc. It is preferable when used for hems, wrists such as gloves, and supporters.

And vinylon fiber yarns, cotton and other natural fiber yarns, and spun yarns (including blended yarns), multifilament yarns (including blended yarns, and processed yarns such as bulky processed yarns are preferred). Of these, polyester bulky processed yarn is preferred. The thickness of these yarns to be used is not particularly limited, but usually about 55 to 220 dtex (in the case of natural fiber yarn, the thickness corresponding to the polyester fiber yarn) is preferable.

  Further, although not particularly limited, examples of the elastic yarn (E) [corresponding to L2 in the embodiment] include a polyurethane elastic yarn and a polyetherester elastic yarn. Usually, a bare type polyurethane elastic yarn without covering is preferred. The thickness of these threads to be used is not particularly limited, but is usually preferably about 55 to 220 dtex.

  Although not particularly limited, the insertion yarns (B1) and (B2) constituting the insertion tissue (corresponding to L5 and L3 in the present embodiment example) are a combination of inelastic yarns and thermal bonding yarns. Except for the thermal bonding yarn portion of the yarns (D1) and (D2), for example, polyester fiber yarn, polyamide fiber yarn, acrylic fiber yarn, polypropylene fiber yarn, vinylon fiber yarn, cotton and other natural fiber yarns, etc. , Spun yarn (including blended yarn), multifilament yarn (including blended yarn, and processed yarn such as bulky processed yarn is preferred).

The thickness of these yarns to be used is not particularly limited, but usually about 55 to 220 dtex (in the case of natural fiber yarn, the thickness corresponding to the polyester fiber yarn) is preferable.

  In the case of using a transparent monofilament yarn as the inelastic yarn of the alignment yarn (D1) of the inelastic yarn and the thermal bonding yarn, various monofilament yarns such as nylon, polyester, polypropylene, polyethylene and the like can be mentioned, Although it does not specifically limit, about 55-220 dtex is preferable normally. Among these, nylon monofilament yarn is preferable.

  The heat-bonding yarn is also expressed as a heat-fusible fiber yarn. As the heat-bonding yarn, the non-elastic yarn used in (D1) or (D2) and the light-reflecting yarn (C) are heat-bonding yarns. There are no particular limitations as long as it can be melted and bonded, and various known types such as a low-melting point copolymer nylon-based thermal bonding yarn, a low-melting point copolymerized polyester-based thermal bonding yarn, and a low-melting point copolymerized polyolefin-based thermal bonding yarn What is necessary is just to select and use what can adhere | attach the said inelastic thread | yarn and light-reflective thread | yarn (C) by the hot-melt adhesion | attachment of the heat | fever adhesive thread | yarn from these heat | fever adhesive threads.

No. [0022] to [0025] and JP-A-10-295417 [0029] to [0033], etc., known retroreflective film yarn, phosphorescent reflective film yarn, aluminum, gold Various known materials, such as so-called gold and silver threads, which are formed by vapor-depositing a metal or alloy capable of forming a gold color or silver color such as silver or copper on a plastic film such as polyester, polyamide, polypropylene, or polyvinyl chloride and slitting it to a narrow width Can be used. Any of light-reflective film yarn having a light-reflecting surface formed on only one surface, light-reflective film yarn having a light-reflecting surface formed on both surfaces, gold yarn wound around the core yarn with these film yarns, and silver yarn may be used. . Most preferred is a retroreflective film yarn.

  The warp knitted fabric of the present invention thus obtained is a light-reflective warp knitted fabric having stretchability in which ridges and grooves are alternately and repeatedly formed in a direction parallel to the wale direction. FIG. 13 shows an example of an outline of the cross-sectional shape of the cut surface when the warp knitted fabric is cut in the course direction (warp direction) [when the elastic yarn of the structure of the elastic yarn (E1) is used]. A schematic perspective view of this is shown in FIG. FIG. 15 shows an outline of the cross-sectional shape of the cut surface when the warp knitted fabric of the present invention is cut in the course direction (warp direction) when the elastic yarn having the structure of the elastic yarn (E2) is used.

  Assuming that the upper side is the front side of the warp knitted fabric of the present invention, "the ridge and groove" means that the convex part on the surface side viewed from the front side indicates the ridge 3, and is recessed when viewed from the front side. The part shows the groove 4. When viewed from the back side, the ridge 3 that is convex on the front side when viewed from the front side becomes a portion 3 'that is recessed on the front side when the back side is used as a reference, and the groove viewed from the front side. 4 is a warp knitted fabric having a cross-sectional structure that forms a convex portion 4 ′ on the back surface side. In other words, the cross-sectional shape of the cut surface when cut in the course direction (warp direction) is bellows or zigzag. It is an elastic warp knitted fabric having a shape approximate to the shape. In the present invention, a knitted fabric having such a shape is expressed as “a light-reflective warp knitted fabric having stretchability in which ridges and grooves are alternately formed in the longitudinal direction parallel to the wale direction”. is there. In FIG. 14, 5 shows a light reflective thread | yarn (C). 13 to 15, an arrow Y indicates a course direction (knitting direction, longitudinal direction). In FIG. 15, the elastic yarn is composed of a single or plural loop structural units (e1) and the single or plural loop structural units (e1) floating and connected to each other without insertion in the course direction (e3). ) When the elastic yarn (E2) having a structure consisting of alternating repetitions is used, the cross-sectional shape of the cut surface when the warp knitted fabric of the present invention is cut in the course direction (warp direction) is the same as in FIG. Schematic embodiment]. As described above, since the portion of the structural unit (e3) that floats and connects between (e1) without insertion is not inserted into the loop, it is not integrated into the warp knitted fabric. The warp knitted fabric groove 4 and the groove 4 (on the back side reference, the convex side portions 4 'and 4' on the back side are connected to the back side of the warp knitted fabric part of (E2) It becomes the structure where the part appears. Reference numeral 2 denotes an elastic yarn appearing on the back surface. Also in (E2), the warp knitted fabric of this embodiment has the shape and function of the warp knitted fabric shown in the perspective view shown in FIG. 14 except that the elastic yarn 2 is slightly visible on the back side surface. Therefore, a perspective view is omitted, and unless otherwise specified, FIG. 14 may be referred to instead.

  As described above, the light-reflective warp knitted fabric of the present invention has a structure composed of alternating one or more loop tissue units (e1) and one or more inserted tissue units (e2) in the course direction. The elastic yarn (E1) or the structural unit (e3) in which the single or plural loop structural units (e1) and the single or plural loop structural units (e1) are floated and connected to each other without insertion in the course direction. By the stretching force of the elastic yarn (E2) of the structure consisting of alternating repetitions, ridges and grooves having a longitudinal direction in a direction parallel to the wale direction are alternately formed, and the light-reflective yarn 5 also has a right angle between the ridges and the grooves. Because it is inserted in a direction that crosses the direction and is folded according to the shape of the ridge and groove, even if the knitted fabric is stretched in the course direction, the heel and groove will be flattened, Elasticity by elastic yarn Therefore, even if the light-reflective yarn itself is not made of a stretchable material, it can be stretched while the ridges and grooves are flattened according to the stretch of the knitted fabric. The non-elastic yarn of the alignment yarn (D1) is bonded to the light-reflecting surface side of the light-reflective yarn at the intersection of the light-reflective yarn by the heat-bonding yarn, and the non-elastic yarn and the heat-bonding yarn are aligned. Since the non-elastic yarn of (D2) is bonded to the light-reflective yarn on the side opposite to (D1) at the intersection where the heat-bonding yarn crosses the light-reflective yarn, the light-reflective yarn is displaced from the knitting structure. It is possible to provide a light-reflective warp knitted fabric having stretchability that can be stretched extremely greatly in the course direction because the fabric can be stretched by the principle of stretching the so-called bellows-like knitted fabric without being pulled out or pulled out. In addition, in the above embodiment, only one L5a (shown in FIG. 7) is attached to the light reflecting surface side of the light reflecting yarn at the intersection crossing the light reflecting yarn to hold the light reflecting yarn. As for the aspect, each of L5a and L5b is one) and there are few yarns that obstruct the light reflecting surface side of the light reflecting yarn, so that the reflected light from the reflecting surface of the light reflecting yarn is not obstructed. It is possible to provide a light-reflective warp knitted fabric having elasticity that can reduce the decrease in force. Further, when a transparent monofilament yarn is used as the inelastic yarn of (D1) as in the above embodiment, the function of blocking the reflected light from the reflection surface of the light reflective yarn is more excellent, which is preferable.

  The light-reflective warp knitted fabric having stretchability according to the present invention is not particularly limited, but can usually be knitted using a single raschel warp knitting machine or a double raschel warp knitting machine. If necessary, the design of the knitted structure can be modified to a double raschel warp knitted fabric to make a double raschel warp knitted fabric, but it will be slightly thicker and its elasticity will tend to decrease slightly. Therefore, a single raschel warp knitted fabric is preferable.

  In addition, as an example, in the knitted fabric of the embodiment shown in FIGS. 1 to 3, L1 is 167 dtex polyester bulky processed yarn, L2 is 155 dtex polyurethane yarn (bear type), L3 and L5 are 167 dtex polyester bulky Processed yarn, 155dtex transparent nylon monofilament yarn as L5a (Thermo-adhesive yarn used for L5a and L3a is low melting nylon yarn "Elder" manufactured by Toray Industries, Inc.), and L4 as a polyester film base with a width of 1 mm Warp knitted fabric obtained by knitting using heat-resistant film yarn ("Retroreflective tape" manufactured by Maruhito Co., Ltd.) and heat finishing at 120 to 130 ° C for 5 minutes is performed by hand in the knitting direction (course direction). When pulled and stretched, the length in the original knitting direction is 100%. Can extend about 0% light reflective yarn to revert is shifted or the knitting structure, nor did or exit.

  The light-reflective warp knitted fabric having stretchability according to the present invention comprises sportswear, jumpers, cuffs of outerwear such as other outerwear including work clothes, wrists such as heels, hem portions, trouser hems, and gloves. It can be used for parts that require stretchability, such as parts and supporters. As an example, as shown in FIG. 16, an embodiment is shown in which the light-reflective warp knitted fabric having stretchability of the present invention is used in a cylindrical shape at the cuff 7 of the outerwear of sportswear. In FIG. 16, the light-reflective warp having the stretchability of the present invention is also applied to the heel 8 and the bottom portion 9 of the outerwear of sportswear so that the stretch direction is the longitudinal direction of the light-reflective thread 5. Knitted fabric is used. Furthermore, FIG. 17 showed the aspect which used the light-reflective warp knitted fabric which has the elasticity of this invention for the part of the skirt part 8 of the trousers of sportswear in the shape of a cylinder. In any case, the light-reflective thread 5 may be worn in a direction in which the light-reflective thread 5 rotates around the cuff 7 or the hem 8 (this direction is the knitting direction and the direction in which the stretchability is large) It can be easily stretched and worn, and even if this part is stretched and worn, the light-reflective yarn does not slip out of the knitted structure or come out. When a knitting structure that does not stretch so much is employed, the light reflective yarn is not stretchable, and therefore cannot be used in a direction in which the light reflective yarn 5 turns around the cuff 7 or the hem 8. Like the light-reflective flat yarn 3 of FIG. 5 and FIG. 6 of JP-A-10-226940, the direction of the light-reflective flat yarn 3 is along the longitudinal direction of the leg or the longitudinal direction of the sleeve. Therefore, the present invention can provide a light-reflective warp knitted fabric having more excellent stretchability in this respect.

  The light-reflective warp knitted fabric having stretchability of the present invention is extremely stretchable and can be stretched without stretching or slipping out of the light-reflective yarn from the knitted structure even after stretching. The light-reflective warp knitted fabric having stretchability according to the present invention comprises sportswear, jumpers, cuffs of outerwear such as other outerwear including work clothes, wrists such as heels, hem portions, trouser hems, and gloves. It can be effectively applied to parts and supporters that require elasticity.
