Description

  The present invention relates to a warp knitted fabric capable of obtaining a soft texture.

  A general warp knitted fabric having a soft texture (feel, feel) such as velour has a raised portion (raised portion) on its surface. The raised portion is composed of a thread having a substantially constant length arranged at a high density, and is raised toward the outside. The raised portion is formed by subjecting the sinker loop to a raising process to form a pile surface, and then performing a cutting process (so-called shearing process) on the pile surface (see Patent Document 1). The raised portion can also be formed from two knitted fabrics knitted by a double raschel knitting machine. In this case, the two knitted fabrics are connected by a connecting yarn therebetween. The connecting yarns are separated into the respective knitted fabrics by the cutting of the connecting yarns, and the cut connecting yarns constitute napped portions of the respective knitted fabrics.

  As described above, in order to give a soft texture to the surface of the fabric, a raising process for the sinker loop and a shearing process for forming a raised portion are executed. Even in a knitted fabric knitted by a double raschel knitting machine, it is necessary to cut the connecting yarn. Since these are independent processes from the knitting of the knitted fabric, it is necessary to use a dedicated machine such as a shearing machine. In other words, in order to produce a soft texture, a dedicated facility for that purpose is inevitably necessary, and therefore the number of work steps increases. An increase in work processes affects production.

  In view of such circumstances, an object of the present invention is to provide a warp knitted fabric in which a velor-like soft texture can be obtained without performing brushing or shearing.

  One aspect of the present invention is a warp knitted fabric, a ground structure formed of chain stitches connected in a wale direction by a sinker loop, and inserted in a reverse manner with respect to each stitch of the ground structure, and the sinker loop Inserted into the stitch of one chain stitch that becomes the starting point of one of the sinker loops and the stitch of the other chain stitch that becomes the end of the other sinker loop of the sinker loops, A first insertion thread that intersects a sinker loop of a chain knitting located between a chain knitting forming a chain knitting and a chain knitting forming the other sinker loop, and a second insertion inserted into each wal of the ground structure The gist is to provide a yarn.

  The second insertion thread may have stretchability.

  FIG. 1 is a diagram showing the organization chart of the warp knitted fabric of the present embodiment, in other words, the movement path of each kite in the warp knitting machine. FIG. 2 is a three-dimensional enlarged view showing only the chain stitch of the warp knitted fabric according to the organization chart of FIG. 3 and 4 are three-dimensional enlarged views for explaining that the chain knitted sinker loop is lifted in the warp knitted fabric according to the organization chart of FIG.

  The warp knitted fabric of this embodiment is knitted by a warp knitting machine such as a Russell knitting machine. The needle density of the warp knitting machine at this time is, for example, 18 to 28 G (gauge). As shown in FIG. 1, the warp knitted fabric of the present embodiment is knitted using at least three heels of a front heel L1, a middle heel L2, and a back heel L3. A ground yarn 12 for knitting the chain stitch 11 is passed through the front collar L1. An insertion thread (first insertion thread) 14 is threaded through the intermediate collar L2. An insertion thread (second insertion thread) 16 to be inserted into the ground structure 10 is threaded through the rear heel L3 along each wale W. Hereinafter, for convenience of explanation, the front heel L1, the middle heel L2, and the rear heel L3 are simply referred to as 筬 L1, 筬 L2, and 筬 L3, respectively.

  As shown in FIGS. 1 and 2, the basic shape (knitting structure) of the warp knitted fabric of the present embodiment is constituted by a ground structure (base fabric) 10 including a plurality of chain stitches 11. The chain stitches 11 constituting the ground texture 10 are connected in the wale direction by sinker loops 12a. The sinker loops 12a of the chain stitches 11 are arranged between the same course. The ground organization 10 is formed based on, for example, the knitting pattern (organization) of the heel L1 shown in FIG. This knitting pattern is a knitting pattern (24/42/24/20/02/20 //) when forming a 6-course tulle. That is, using the ground yarn 12, (a) knitting (knitting) stitches for three courses on the wale W, (b) then forming the sinker loop 12a and moving to the right wale W, (c) In the moved wale W, the stitches for three courses are knitted (knitted), (d) the sinker loop 12a is formed and the original wale W is moved, and the steps (e), (a) to (d) are performed. The chain stitch 11 is formed by repeating. As shown in FIG. 2, the stitch 11b of the chain stitch 11 that is the end point of the sinker loop 12a (the open stitch in FIG. 2) is the stitch 11a of the other chain stitch 11 that is the starting point of the other sinker loop 12a (FIG. 2). In this case, they are connected to a closed eye) and arranged on one wale. Thereby, the plurality of chain stitches 11 are connected to each other, and as a result, the ground texture 10 is formed.

  The knitting pattern of the heel L2 when knitting the insertion yarn 14 is, for example, the knitting pattern (texture) (00/22/00/44/22/44 //) shown in FIG. As shown in this figure, the insertion yarn 14 is inserted into each stitch of the ground structure 10 (chain stitch 11) in a reverse manner with respect to the knitting of the chain stitch 11. As shown in FIG. 3, the insertion yarn 14 is inserted into the stitch 11 a of one chain knitting 11 and the stitch 11 b of the other chain knitting 11. Here, the stitch 11a is a stitch that is a starting point of one sinker loop 12aa among the plurality of sinker loops 12a arranged between the same course, and the stitch 11b is an end point of the other sinker loop 12ab. It is a stitch. Thus, the insertion yarn 14 is inserted into each stitch 11a, 11b so as to straddle between the stitch 11a and the stitch 11b, and between the chain stitch 11 forming the stitch 11a and the chain stitch 11 forming the stitch 11b. It intersects with the sinker loop 12ac of the chain stitch 11 located. Note that, as in a modified example shown in FIG. 6 (described later), the number of sinker loops with which the insertion yarn 14 intersects varies depending on the number of wales W that the sinker loop 12a straddles.

  That is, as shown in FIG. 3, when paying attention to one sinker loop 12ac, different insertion yarns 14 are entangled with the ground yarn 12 of the sinker loop 12ac at the start point (region A) and the end point (region B) of the sinker loop 12ac. I understand that This is the same for any sinker loop 12a. Further, as described above, the insertion yarn 14 is inserted into the stitch of the chain stitch 11 in a reverse manner with respect to the knitting of the chain stitch 11. Accordingly, the two insertion yarns 14 are entangled with each other at the start point and the end point of the sinker loop 12a so as to cross the sinker loop 12a in opposite directions.

  The insertion yarn 14 moves so as to be aligned (pulled) in the direction along the wale W after knitting due to the tension applied during knitting of the warp knitted fabric. Therefore, in each sinker loop 12a, the insertion yarns 14 entangled on both sides thereof move in directions away from each other across the sinker loop 12a. By this movement, the length of the sinker loop 12a after knitting of the warp knitted fabric becomes longer than that during knitting. Furthermore, by this movement, the insertion thread 14 causes the sinker loop 12a to float outward (front side) at a portion that intersects the sinker loop 12a. Since the insertion yarn 14 is inserted backward with respect to the stitch of the ground structure 10, the sinker loop 12 a is more external than when the insertion yarn 14 is inserted forward with respect to the knitting of the chain stitch 11. Can stand out. As a result, the floated sinker loop 12a gives a soft texture to the surface of the warp knitted fabric. That is, it is possible to provide a warp knitted fabric in which a velor-like soft texture can be obtained without performing a raising process or a shearing process.

  The insertion thread 16 is inserted into each of the wales W of the ground structure 10 and does not straddle between the two wales W unlike the ground thread 12. That is, the insertion yarn 16 is inserted into the chain knitting 11 composed of different ground yarns 12 knitted into one wale W. This knitting pattern is, for example, 22/00 //. In this case, the insertion yarn 16 is not inserted into the stitch that is the starting point of the sinker loop 12a. That is, since this stitch does not entangle with the insertion yarn 16, it is easily pulled out to the sinker loop 12a side. Accordingly, when the insertion yarn 14 is moved, a part of the ground yarn 12 forming the stitch is pulled out to the sinker loop 12a side, and the length of the sinker loop 12a is further increased. Can be further softened.

The material of the yarn used in this embodiment is as follows.
In this embodiment, a filament yarn is used as the ground yarn 12. The thickness of the filament yarn is, for example, 20d (D, denier) to 210d. As described above, the sinker loop 12a of the chain knitting 11 is lifted outward by the reverse insertion of the insertion yarn 14 into the chain knitting 11. Therefore, the texture strongly depends on the characteristics (thickness, material, constituent fiber) of the ground yarn 12. For example, the filament yarn has a softer texture as its constituent fibers are thinner. The thickness of the constituent fiber of the ground yarn 12 (filament yarn) in the present embodiment is, for example, 2.5 d or less. In addition, each said value does not limit this invention. The ground yarn 12 may be a spun yarn. Further, the ground yarn 12 may be an elastic yarn (stretchable yarn) or a non-stretchable yarn.

  In the present embodiment, a polyester or nylon filament yarn is used as the insertion yarn 14. The thickness of the insertion thread 14 is selected in consideration of the thickness of the ground thread 12. When the thickness of the ground yarn 12 is 20d to 210d, the thickness of the insertion yarn 14 is, for example, 40d to 280d. In addition, it is also possible to use filament yarn other than polyester or nylon, or spun yarn as the insertion yarn 14.

  In the present embodiment, the insertion thread 16 uses a stretchable thread. The insertion yarn 16 is, for example, a yarn including at least a polyurethane-based stretch yarn (so-called spandex). However, as long as the stretchability equivalent to that of the polyurethane-based stretchable yarn is obtained, the stretchable yarn may be a yarn of another material. Examples of such yarn include polyether ester-based or polyester-based stretch yarn. The thickness of the insertion thread 16 is selected in consideration of the thicknesses of the ground thread 12 and the insertion thread 14. This value is, for example, 40d to 420d. By making the insertion yarn 16 stretchable, the warp knitted fabric can be stretched and the sinker loop 12a of the base yarn 12 can be lifted outward when the warp knitted fabric contracts. That is, it is possible to provide a warp knitted fabric having stretchability with a softer texture. When the stretchability of the warp knitted fabric is not required, a non-stretchable yarn may be used as the insertion yarn 16 as long as the sinker loop 12a can be lifted outward.

  Other examples of the above-mentioned stretchable yarn include polyurethane-based filament twisted yarn (FTY), covering yarn obtained by wrapping a polyurethane-based filament with a yarn of other material (for example, nylon), and these polyurethane-based stretchable yarns and non-stretchable yarns For example, a thread that is aligned with a thread. Other examples of the non-stretchable yarn include spun yarn such as cotton and rayon, and filament yarn such as nylon, polyester, and acrylic.

  The number of chain stitches continuously knitted on one wale W is not limited to three as shown in FIG. Further, the number of stitches of the chain stitch continuously knitted on one wale W may be different before and after moving to another wale via the sinker loop. For example, as shown in FIG. 5, five chain stitches are knitted on one wale W using the ground yarn passed through the heel L1, and after straddling another wale W in a sinker loop, Three chain stitches may be knitted with the wale W, and the chain stitch may be knitted again by returning to the original wale W with a sinker loop. On the other hand, the insertion yarn (first insertion yarn) passed through the heel L2 is also inserted in the reverse direction into the chain stitch of each wale W, and inserted at the place where the sinker loop of the ground yarn is formed. Forms a sinker loop of yarn. As described above, the texture can be changed by changing the distance (pitch) along the wale W of each sinker loop pair of the ground yarn and the insertion yarn.

  Further, the sinker loop of the ground yarn threaded through the heel L1 and the sinker loop of the insertion thread (first insertion thread) threaded through the heel L2 may straddle one or more wales W. For example, as shown in FIG. 6, the sinker loop of the ground yarn and the sinker loop of the insertion yarn (first insertion yarn) both straddle one wale W. Thus, the texture can be changed by changing the distance straddling the wale W along the course. In the case of this modification, a knitting pattern in which the ground yarn that has once moved to the other wales W does not move to the original wales but moves to the wales between these wales may be used. Furthermore, knitting combining the above is also possible. In any case, it is possible to provide a warp knitted fabric in which a velor-like soft texture can be obtained without performing a raising process or a shearing process.

  The present invention is not limited to the above-described embodiment, but is shown by the description of the scope of claims, and further includes all modifications within the meaning and scope equivalent to the description of the scope of claims.
