Cotton Viscose Woven Elastic Double Fabric Dyeing And Finishing Technique

Cotton viscose woven stretch double-layer fabric, due to its high moisture absorption, breathable, elastic, soft fullness and draping and many other advantages, more favored by consumers. The fabric weft is cored wire on the spandex core-spun yarn of viscose rayon, and double-layer fabric, dyeing and finishing difficult, easy to produce such as wrinkling and zonal problem of shrinkage and affects product quality. Our company is based on the development of cotton, viscose weaving weft elastic two-layer fabric research, has developed a stable, production, and investment in production.

Rayon wet low strength, wet-back after being stretched and dried, in tandem with the fabrics varies with the stress, generated in the production of "frills". This mode needs to be sewn to arc, arc 1%~1. 25%. Taking into account the zonal characteristics of high-shrinkage, sewing needle-tight needle 24~25/10 cm is appropriate, one should angle joints at both ends and encryption, or in subsequent processing easy to produce in volume, wrinkle and cut cloth and so on.
