100% cotton is greater than 99% cotton; More than 95% of pure cotton is cotton; ; Caleka just adds elasticity and is not easy to deform. Lycra has outstanding ductility. For knitwear, its multidirectional extension is determined by the fabric itself, and Lycra only brings elasticity after stretching. Woven fabrics are extensible only in the direction of weaving into lycra, such as warp knitting (straight direction) or weft knitting (horizontal direction). Pants benefit from warp elasticity, and the two-way elastic woven fabric containing Lycra provides great comfort and two-way free movement. Therefore, when Lycra is added to women's ready-made clothes such as trousers and coats, the wrinkles can be easily and automatically repaired, and the clothes are more free and not easy to deform, elastic and feel free as new. Even if you make a rigorous suit, coat, etc. There is no sense of urgency and bondage. Add a little lycra to sweaters, underwear, fitness pants and other knitwear, which fits comfortably and can be stretched freely and moved with you.
