Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a leggings fabric having excellent breathability,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a leggings fabric having excellent air permeability and capable of forming a pattern of two-tone color freely and having excellent stretching and restoring force, and more particularly, to a twe- (BURN-OUT) at the same time as a part of the polyester yarn is formed by forming a pattern to be realized by carrying out a pigment printing process, and another type of pattern is formed in the embossed pattern, The present invention relates to a method of manufacturing leggings fabrics excellent in stretch and restoring force, free from pattern formation of two-tone colors.

In recent years, not only fitness and yoga have been worn by wearing casual wear or leggings, but also the trend of ATHLEISURE which makes shopping. It is not strange that we wear it in everyday life, but now people wear sportswear garments like leggings in casual wear regardless of whether they exercise or not.

In the past, we made patterns by using a flameproof printing or jacquard seamless machine, or sewing after aligning the altar, and we made leggings clothes to circulate the air.

Conventional sports leggings fabric used for the athletic fashion item has been used as a sponge of a cyclic structure or a tweaw span of a warp knitting structure by embossing or embossing the knit so as to be stretchable.

Therefore, there is a problem in that the fabric is necessarily subjected to post-processing on the surface of the fabric or an additional process is required in the sewing operation, thereby increasing the cost.
