[0002]

2. Description of the Related Art Conventionally, a lace knitted fabric is a lace knitted fabric formed by knitting yarns, and by utilizing the fact that it has some elasticity, the wale of a part or all of the knitted fabric of the lace is used. In addition, there was a lace knitted fabric in which elastic yarns having elasticity such as one rubber yarn were knitted to give elasticity and elasticity in the longitudinal direction. An example of a Raschel knitting machine, which is a kind of lace knitting machine for knitting such a lace knit, is shown in FIG. The Raschel knitting machine 20 includes a knitting portion 24 for knitting the lace knitted fabric 10, a roll 25 for winding the knitted fabric 10 knitted by the knitting portion 24, and a ground yarn 11 made up of the warp yarns 2, the weft yarns 5, etc. A ground beam 21 for supplying

It is configured. In the knitting section 24, a plurality of reeds having guides for guiding the ground yarn 11, the elastic yarns 4, the pattern yarns 6a, etc., a large number of knitting needles for chain-knitting the warp yarns 2, and a large number of the knitting needles are vertically arranged. There is provided a needle hook or the like for guiding (not shown), and the knitted portion 24 is used to form the lace knitted fabric 10.
Is formed and is wound around the winding roll 25. A single course 7 is formed by one reciprocating operation of the knitting needle up and down to form the loop 3 of the wale 1, but detailed description thereof will be omitted. FIG. 4 shows an example of the lace knitted fabric 10 wound around the winding roll 25. Each of the warp yarns 2 of the ground yarn 11 is chain-knitted by one operation of the plurality of knitting needles, and a weft yarn 5 is formed between the loop portion 3a and the sinker portion 3b of the loop 3 that constitutes the plurality of wales 1. It is inserted and connects the wales 1 to form a ground portion 12. In the knitted ground portion 12 of the base yarns 11, through holes 14 having different shapes are formed depending on the course pitch into which the weft yarns 5 are inserted. The elastic yarn 4
Is conventionally knitted by inserting one each along the wale 1 between the loop portion 3a and the sinker portion 3b and the weft yarn 5, and the elastic yarn 4 is in a stretched state. The lace knitted fabric 10 is knitted with the elastic yarn 4, and the stretchability of the elastic yarn 4 is utilized to impart elasticity to the lace knitted fabric 10. Further, the loop portion 3a, the weft yarn 5 and the elastic yarn 4

[0003]

SUMMARY OF THE INVENTION In order to increase the shrinkage force generated when the conventional lace knitted fabric 10 is stretched, the on-machine driving (that is, the distance between the courses 7 on the machine) is made rough and at the same time. , It is necessary to knit the lace knitted fabric 10 while giving a large tension to the elastic yarn 4, but in order to give an even greater contraction force, the elastic yarn 4 is made thicker,
It is conceivable to increase the tension applied to the elastic yarn 4 during knitting. However, when the elastic yarn 4 is thickened and is knitted while applying a larger tension to the elastic yarn 4, as shown in FIG. 3, the knitting portion 24 having the guides to which the elastic yarn 4 is hooked is reed. In some cases, the force of pulling the guide downward is excessively applied, and the load may approach or exceed the allowable load of the reed of the lace knitting machine, which may cause a problem in durability. Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a lace knitted fabric in which the contraction force during stretching can be easily increased.

[0004]

[Means for Solving the Problems]

[Characteristic Configuration 1] The characteristic configuration of the present invention for the above purpose is that a plurality of elastic yarns are knitted together in each of at least a part of the plurality of wales (corresponding to claim 1). [Operation and Effect of Characteristic Configuration 1] Therefore, according to the above characteristic configuration, since a plurality of elastic yarns are knitted in the same wale, the elastic yarns can be hung on a plurality of reeds without significantly changing the tension applied to each elastic yarn. Therefore, the load applied to each reed can be largely changed from the conventional one. As a result, it is possible to increase the contracting force applied to the lace at the time of extension while maintaining the durability of the lace knitting machine in good condition.

[Additional Structure 1 and Operation and Effect] It is sufficient that a plurality of elastic yarns are knitted together (corresponding to claim 2) in all of the plurality of wales described in the above-mentioned Characteristic Structure 1. By doing so, you can further increase the stretching force applied to the race. As a result, the effect of the characteristic configuration 1 can be enhanced.

[Additional Construction 2 and Action and Effect] Further, the two elastic yarns may be crossed with each other and woven into the warp described in the characteristic construction 1 or the additional construction 1 (corresponding to claim 3). Even better, by doing this, by crossing the elastic yarns knitted in the same loop, the frictional resistance of the surface of the elastic yarn is greater than that of other ground yarns or inserted yarns. Utilizing the friction resistance between the intersecting elastic yarns, at the cut end in the length direction of the race,
It is possible to prevent the elastic yarn from shrinking and slipping inward of the lace. Furthermore, since the intersecting elastic yarns are partially fused by the heat applied during the finishing process of the lace knit, it is possible to more reliably prevent the elastic yarns from slipping out. As a result, the effect of the characteristic configuration or the additional configuration 1 can be enhanced.

[Characteristic Configuration 2 and Operation and Effect] In the second characteristic configuration of the present invention for the above purpose, a plurality of elastic yarns are knitted together in at least a part of the plurality of wales, and A part of the elastic yarn is woven (corresponding to claim 4) over a plurality of the wales in at least a part of the course. If you do this,
At the same time that the action of the characteristic configuration 1 is achieved, stretchability can be imparted also between the wales (that is, in the width direction of the race). As a result, the effect of the characteristic configuration 1 can be obtained, and at the same time, stretchability in the width direction can be imparted to the lace knitted fabric.
