Winding device for braid yarn {WARPING DEVICE FOR BRAID}

The present invention relates to a braid yarn winding device, and specifically, to a manufacturing device capable of selectively adjusting the tension applied to the yarn according to the deviation of the depth of the braid yarn manufactured in a cylindrical shape by twisting the yarn in a loop structure. About.

Along with the new menswear trend pursuing a smart look or casual style, knit tie products that emphasize fashion and practicality are attracting attention.

Domestic tie production mainly uses silk as the main raw material, and is developed mainly by jacquard design fabrics, so it is no longer possible to satisfy consumer demand sensibility with only color or design differentiated products, and a new attempt from yarn is required.

For the development of new knit tie products, it is necessary to develop differentiated materials of natural composites, but when knitting with a circular knitting loom, there are limitations in the knitting process such as constant fineness, knitting yarn tension, and wool, and in the case of knit tie, yarn of a certain thickness (700D ~ 800D). However, in order to give this level of thickness and volume, various problems may occur in the weaving process as several yarns are passed through one guide.

Therefore, the development of a device for manufacturing 500D (denia) ±50 class and 1000D ±100 class braid through a combination of different materials and diversification of colors and materials that can be applied to woven fabrics and cannot be secured with a single material. This is an urgent situation.
