The double-covered yarn has two outer layers of filaments or yarns wrapped within the spandex Main, and these two layers are frequently in reverse directions. The Main spandex is covered to a fantastic extent along with the core publicity is a lot less, and because the outer wrapped filaments are wrapped with opposite spiral angles symmetrically around the Main filaments, the elasticity in the wrapped yarn is nicely well balanced and might usually be processed during the later on process without shaping therapy, but the processing expense of double wrapped yarn is larger. It is especially employed for elastic fabrics like leg guards, elastic belts, sock openings and tights.

Along with the spandex stretch need in ACY, SCY has A different significant process parameter would be the twist. Twist might make a big difference in high-quality, elongation and evenness. Boost the twist to raise the drive of Keeping in between the outer covering fibre and also the spandex yarn, building the covering yarn much better.

It doesn’t adapt for making deep colour merchandise, it’s mostly useful for socks, weft knitted underwear and various stretch weaving.

Fortune Cat® Elastic Yarn Manufacturing unit was recognized in 2005 in Jiangsu, the most crucial output plant reaches much more than a hundred,000 sq. meters. With a myriad of elastic yarn/gum yarn manufacturing as its major organization, the manufacturing facility is now one of the most important gun yarn factories in China.

Response with bleaches: It maintains resistance at temperatures underneath one hundred fifty°F. Scientists are attempting to Enhance the problem.
