Problems solved by technology

In this case, as for the braided lace formed by heating the lace braid, it is still easy to cause fraying outside the ruffle part.
In addition, after the braided lace is manufactured, there are cases where the thermally bonded thread becomes detached from the remaining thread
In this case, the bonding of multiple threads generated by the thermal bonding thread is released, and fraying may occur from the separated part.

Embodiment Construction

[0051] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0052] figure 1 It is a weaving structure diagram which schematically shows a part of the knitted lace fabric 120 which is the first embodiment of the present invention. figure 2 It is a weaving structure diagram schematically showing a part of the first precursor knitted fabric 20 which is the precursor of the lace knitted fabric 120 . FIG. 3 is a diagram schematically showing the weaving structure of the first precursor knitted fabric 20 omitting the chain knitting yarn 21 and the thermal bonding yarn 23 . figure 1 ˜ FIG. 3 is a diagram schematically showing a weaving structure for easy understanding. The actual weaving structure of the lace knitted fabric 120 and the first precursor knitted fabric 20 is the curvature of the first annular portion 24 and the second annular portion 25. Small and the wires 21, 22, 23 are extremely clos...

Abstract

A lace knitted fabric, and process for producing the same, capable of not only suppressing disfiguration but also preventing yarn fraying. Lace knitted fabric (120) after knitting operation is heated at a temperature which is below the melting temperature of chain stitch yarn (21) but not lower than the melting temperature of hot melt yarn (23) so that the hot melt yarn (23) is partially melted. Portion of the molten part sticks to the chain stitch yarn (21) and inserting yarn (22). As a result, the linking state of individual yarns (21-23) can be maintained to thereby prevent fraying of the yarns. Further, fusion bonded portion (100) can be formed by fracturing the hot melt yarn (23). Consequently, even when portion of the chain stitch yarn (21) constituting the chain stitch texture is segmentalized, fraying of the chain stitch texture can be prevented by the stuck portion of the hot melt yarn (23) so that fraying of the chain stitch texture beyond the stuck portion can be inhibited.

Description

technical field [0001] The present invention relates to a method for producing lace and a lace produced by the method. Background technique [0002] The lace braid disclosed in Japanese Patent Publication No. 63-52142 is made by weaving heat-melting heat-adhesive threads into the ruffles. After weaving, the lace braid is heated to melt the thermal bonding thread. The thermal bonding line is formed by bonding the overlapping portion between the base of the trim thread and other threads, and fusing the exposed portion of the thermal bonding line except for the overlapping portion. This prevents the ruffled part from fraying on the braided lace. [0003] The lace braid disclosed in Japanese Patent Laying-Open No. 11-81073 is formed by weaving a core-spun yarn into a ruffle. The core-spun yarn is composed of a heat-fusible core yarn and a cover yarn which is a thermoplastic synthetic fiber yarn. After weaving, by heating the lace braid, a part of the core yarn in the core-sp...
