FIG. 6 is a cross-sectional view of the lace fabric 1 forming the bypass portion 110 and the bypass portion 111. The lace fabric 1 in which the bypass part 110 bypass part 111 is not formed, and the bypass part 110 bypass part 111 are the figures showing the formed lace fabric 1. Bypass part 110 It is a table | surface which shows the pattern of the knitting method which forms bypass part 111. FIG. Sample 1 and Sample 2 are photographs of lace fabric 1. It is a figure explaining the process thread | yarn 14 holding the heat sealing thread | yarn 14e. A variant of two spans with different movements. The different movements maintain the feel of the touch and also allow for partial strengthening of the tissue.

The background and outline of this embodiment will be described.
A lace is a cloth made of net-like watermarks by twisting or combining yarns. In addition, the lace may be pleated in order to make the lace pattern appear in three dimensions and to maintain the stretchability. However, it was difficult to maintain pleating, as the lace is often stretched forcibly by washing or the like. Therefore, in order to hold the form of pleats for a long time, a manufacturing method in which an elastic yarn is knitted on a lace fabric to form a pleat is disclosed as a prior art. However, in laces used for underwear and the like, it is necessary to consider the texture of the part in contact with the skin directly in contact with the skin in addition to maintaining the three-dimensional pattern and elasticity of the race. Therefore, according to the present invention, one span weir is additionally provided on a span weir which originally has only one at the back of the Raschel machine, and two span weirs are arranged to be inserted alternately into warp yarns. , So that the machined yarn can be formed by repeating two patterns of weave / bypass / weft / bypass in the knitting direction and alternately arranging it on adjacent warps, so that the bypass is evenly on the back of the lace ground By making it possible to disperse, it achieved a soft touch with the stretch retention of the lace fabric and the beauty of the handle.

Hereinafter, the configuration of the embodiment of the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the illustrated example.

FIG. 1 is a view for explaining the configuration of a lace fabric 1 according to the present embodiment.
FIG. 2 is a view for explaining the configuration of the processed yarn 14 according to the present embodiment.
As illustrated in FIG. 1, the lace fabric 1 has a warp 10, a weft 12, and a processed yarn 14. The warp yarns 10 and the weft yarns 12 are inelastic yarns that are less stretchable than the elastic yarns 14a (described later). Specifically, the warp 10 and the weft 12 are polyamide synthetic fibers. In this example, the material of the warp 10 and the weft 12 is nylon, which has characteristics such as high strength, easy to remove stains, and excellent quick-drying property.
The lace fabric 1 is formed of a warp and a lace pattern by inserting the weft yarn 12 in a continuous loop in the warp direction formed by the warp 10.

Further, as illustrated in FIG. 4, the processed yarn 14a and the processed yarn 14b are composed of an elastic yarn 14c and a coated yarn 14d. Specifically, the processed yarn 14a has the elastic yarn 14c as a core, and the coated yarn 14d is spirally wound around the surface of the elastic yarn 14c. The elastic yarn 14 c is a yarn that is more stretchable than the warp yarn 10 and the weft yarn 12. Specifically, the elastic yarn 14c is a polyurethane fiber, and as a feature thereof, the elastic yarn 14c is a fiber thinner than rubber in addition to stretchability, has higher strength than rubber, and has characteristics such as lightness. .
The covering yarn 14d is a spring having elasticity such as spring and bulkiness such as a yarn, and in this example, the covering yarn 14d is a woolly yarn. Wooly yarn is a yarn processed to give elasticity and bulkiness to raw silk, and when it is used for textiles, textiles generally feel better and softer to the skin than those using twisted yarns Finished.
That is, since the coated yarn 14d having the bulkiness is wound around the elastic yarn 14c, the textured yarn 14a is bulkier than the elastic yarn 14c alone.

As illustrated in FIG. 1, the machined yarn 14 a and the machined yarn 14 b are alternately knitted left and right alternately on the warp yarn 10 forming the lace fabric 1, and the knitted portion is the braided portion 100 braided portion 101. Further, a portion where the machined yarn 14 a and the machined yarn 14 b are not woven into the warp yarn 10 is the bypass portion 110 and the bypass portion 111. Specifically, the bypass portion 110 and the bypass portion 111 correspond to five or less loop portions which are stitches formed by the warp yarn 10 and the machined yarn 14 a and the machined yarn 14 b. Further, the braided portion 100 and the bypass portion 110 in the lace fabric 1 are alternately arranged at least in the warp direction of the warp. Further, the bypass portion 110 and the bypass portion 111 may correspond to five or less loop portions which are stitches formed by the warp yarn 10 and the processed yarn 14 a and the processed yarn 14 b. In this example, the braided portion 100 corresponds to seven stitches of the warp yarn 10, and the bypass portion 110 corresponds to five stitches of the warp yarn 10.

FIG. 3 is a cross-sectional view of the lace fabric 1 forming the bypass portion 110. As shown in FIG.
FIG. 3A is a cross-sectional view of the lace fabric 1 in the case where the bypass portion 110 and the bypass portion 111 correspond to 25 stitches of the warp yarn 10. FIG. 3B is a cross-sectional view of the lace fabric 1 in the case where the bypass portion 110 of the present invention corresponds to three stitches of the warp yarn 10.
3A and 3B, at the braided portion 100 and the braided portion 101, the machined yarn 14a and the machined yarn 14b are braided into the warp yarn 10, whereby the machined yarn 14a and the machined yarn 14 are processed. The elastic yarn 14c forming the yarn 14b is pulled left and right, and the covering yarn 14d wound around the elastic yarn 14c also extends left and right. Therefore, the bulkiness is smaller than that of the processed yarn 14a and the processed yarn 14b which are not pulled left and right. On the other hand, in the bypass portion 110 and the bypass portion 111, since the machined yarn 14a and the machined yarn 14b are not woven into the warp yarn 10, the force (tension) by which the elastic yarn 14c is pulled laterally from the braided portion 100 is weak. The coated yarn 14d is also the same. Therefore, the bulkiness of the processed yarn 14 a and the processed yarn 14 b is higher than that of the braided portion 100 and the braided portion 101. Further, in the bypass portion 110 and the bypass portion 111, a crease is formed in the lace fabric 1 knitted by the warp yarn 10 and the weft yarn 12 by the elastic yarn 14c having a smaller tension than the braided portion 100, and a pleat 120 is formed. The pleated portion 120 provides an effect that the lace pattern looks three-dimensional. That is, by the bypass part 110 bypass part 111, the processed yarn 14 bulkiness is maintained and a pleat shape is formed. Further, the textured yarn 14 a and the textured yarn 14 b having stretchability and bulkiness are exposed on the back surface of the lace fabric 1 by the bypass unit 110 and the feel of the back surface of the lace fabric 1 feels soft.

When the pleat portion 120 of FIG. 3A and the pleat 120 of FIG. 3B are compared, the number of stitches of the warp yarn 10 forming the bypass portion 110 and bypass portion 111 of FIG. The processed yarn 14a and the processed yarn 14b exposed on the back surface of the lace fabric 1 are smaller than the number of stitches of the warp yarn 10 forming the bypass portion 110 and the bypass portion 111 of A). It is less than the processed yarn 14a and the processed yarn 14b exposed on the back surface of the belt. However, in the single bypass portion 110 bypass portion 111 of FIG. 3A, since the processed yarn 14a and the processed yarn 14b exposed on the back surface of the lace fabric 1 become long, when the entire lace fabric 1 is touched, FIG. The lace fabric 1 of (B) is more easily caught and the processed yarn 14a and the processed yarn 14b are more likely to come off. Therefore, in order to realize a smooth and soft touch while forming the bypass portion 110 bypass portion 111, the length of the braided portion 100, the length of the bypass portion 110 bypass portion 111, and the braided portion 100 braided portion It is necessary to take into consideration the ratio between the ratio 101 and the bypass unit 110.

FIG. 4 is a view showing the lace fabric 1 in which the bypass portion 110 and the bypass portion 111 are not formed and the lace fabric 1 in which the bypass portion 110 and the bypass portion 111 are formed. FIG. 4A shows the lace fabric 1 in which the elastic yarn 14 c is warped without forming the bypass portion 110 and the bypass portion 111 in the warp yarn 10. In the case of the lace fabric 1 shown in FIG. 4A, since the elastic yarns 14c are woven into the loops of all the warp yarns 10, the elastic yarns 14c do not slack and the entire lace fabric 1 becomes hard. Moreover, since there is no bypass part 110 bypass part 111 in the lace | dye 1 of FIG. 4 (A), a three-dimensional pattern and elasticity can not be maintained.
FIG. 4B shows the lace fabric 1 knitted while forming the bypass portion 110 and the bypass portion 111 in the warp yarn 10 of the processed yarn 14a and the processed yarn 14b. In the case of the lace fabric 1 of FIG. 4B, since the bypass portion 110 and the bypass portion 111 are formed, the processed yarn 14a and the processed yarn 14b are not knitted in the loops of all the warp yarns 10, The processed yarn 14a and the processed yarn 14b of the bypass portion 110 and the bypass portion 111 exposed on the back surface of the lace fabric 1 are woven into the warp yarn 10 when compared with the elastic yarn 14c present on the back surface of the lace fabric 1 of FIG. The tension on the machined yarn 14a and the machined yarn 14b generated due to the above is small, and the machined yarn 14a and the machined yarn 14b are more slack than the elastic yarn 14c of FIG. 4 (A). Moreover, since the bypass part 110 bypass part 111 is formed, the processed thread 14 exposed to the back surface of the lace fabric 1 of FIG. 4 (B) is an elastic thread exposed to the back surface of the lace fabric 1 of FIG. The back surface of the lace fabric 1 of FIG. 4B is softer than the back surface of the lace fabric 1 of FIG. Further, in FIG. 4B, since the processed yarn 14 in which the covering yarn 14d is wound around the elastic yarn 14c is used, the bulkiness of the lace fabric 1 is increased compared to the case where only the elastic yarn 14c is used. Becomes softer.

FIG. 5 is a table showing a pattern of knitting to form the bypass portion 110 and the bypass portion 111. Sample 1 is obtained by knitting machined yarn 14a and machined yarn 14b in six continuous loops of warp yarn 10 (braided portion 100 and braided portion 101), and then machined yarn 14 in five loops of continuous warp yarn 10. (Bypass Unit 110 Bypass Unit 111) This is repeated to knit the lace fabric 1. The polyurethane flying rate is 41.7%, which indicates the number of unbraided loops of the processed yarn 14 with respect to the number of all loops of the warp 10 in the case of the sample 1.
Sample 2 forms braided portion 100 braided portion 101 by three continuous loops of warp yarn 10, and then forms bypass portion 110 bypass portion 111 by three continuous loops of warp yarn 10, and braided portion 100 braided portion 101 The bypass portion 110 and the bypass portion 111 are repeatedly formed to knit the lace fabric 1. The polyurethane fly rate in the case of sample 2 is 50.0%.

When samples 1 to 2 are compared, it is sample 2 that the degree of softness on the back surface of the lace fabric 1 is large and smooth. When the bypass portion 110 bypass portion 111 is larger than the sample 2, the length of the processed yarn 14 forming one bypass portion 110 bypass portion 111 pops out on the back surface of the lace fabric 1 becomes longer. The processed yarn 14 that pops out may be too long and be caught, and the back surface of the smooth lace fabric 1 can not be formed. Furthermore, when the bypass part 110 bypass part 111 is larger than the sample 2, the pleat part 120 to be formed becomes large, the pleat part 120 becomes noticeable on the surface of the lace fabric 1, and the design property is reduced. Further, when the bypass portion 110 bypass portion 111 is smaller than the sample 2, it is difficult to maintain the form of the bypass portion 110 bypass portion 111, and the same as the back surface of the lace fabric 1 where the bypass portion 110 bypass portion 111 is not formed It feels like it. If the ratio of the bypass portion 110 and the bypass portion 111 is too high, the yarn may come off, so it is preferable that the bypass portion 110 and the bypass portion 111 be 50% to 60% of the entire lace fabric 1. As mentioned above, the degree of softness of the back of lace fabric 1 becomes the largest, maintaining the surface design nature of lace fabric 1 formed repeatedly by 3rd braided part and 3rd bypass part.
Furthermore, as illustrated in FIG. 6, when the sample 1 and the sample 2 are compared, the length of the bypass portion 110 bypass portion 111 of the lace fabric 1 is shorter in the sample 2 and the smaller bypass portion 110 bypass portion 111 In the sample 2, the design of the surface of the lace fabric 1 is ensured, and at the same time, the back surface of the lace fabric 1 is smoother in touch.

As described above, according to the present invention, the braided portion 100 in which the processed yarn 14 having elasticity is knitted on the warp yarn 10 in the lace fabric 1 formed by the warp yarn 10 and the weft yarn 12; And the bypass portion 110 and the bypass portion 111 where the knitting of the machined yarn 14 is removed. By forming the bypass portion 110 and the bypass portion 111, the processed yarn 14 forming the bypass portion 110 and the bypass portion 111 of the lace fabric 1 is present in a slack state. Further, the machined yarn 14 is formed of an elastic yarn 14c having elasticity and a coated yarn 14d having bulkiness, and the back surface of the lace fabric 1 has a soft feel and the nature of the slacked yarn 14. Become.
Furthermore, by forming the braided portion 100 and the bypass portion 110 and the bypass portion 111 in the lace fabric 1 at an optimum interval, smoother touch and maintenance of a three-dimensional pattern are realized.

A modification of the above embodiment will be described.
In the present embodiment, it is not limited to this that it is composed of the processed yarn 14 and the covering yarn 14d, and for example, as illustrated in FIG. 7, the heat-fusion yarn 14e is wound around the elastic yarn 14c. Further, it may be a processed yarn 14 around which the covering yarn 14d is wound. The heat-laid yarn 14e is melted by heat treatment with wet heat or dry heat to bond the elastic yarn 14c and the coated yarn 14d. This makes it possible to prevent the elastic yarn 14c from coming off the lace fabric 1.

In the present embodiment FIG. 1 is configured for the purpose of achieving a soft touch by holding an elastic property and holding a beautiful image of the handle of the table while keeping the feel of the lace fabric in a good condition. The present invention is not limited to this, and for example, as illustrated in FIG.
By arranging the processed yarn 14b, it is possible to strengthen the retention of the picot yarn 130 from the lace fabric 1, to stabilize the structure around the picot yarn 130, and to improve the physical properties of quality.
