Staple-covered yarn is preprocessed by one or more yarns patched together and afterwards twisted about the spool by a twisting machine. both of those the covered yarn plus the outer covering yarn is usually witnessed.

The double-covered yarn has two outer layers of filaments or yarns wrapped throughout the spandex Main, and both of these layers are typically in reverse Instructions. The Main spandex is covered to a good extent and also the core publicity is a lot less, and since the outer wrapped filaments are wrapped with reverse spiral angles symmetrically around the core filaments, the elasticity in the wrapped yarn is properly well balanced and will frequently be processed in the later method with no shaping treatment method, although the processing price of double wrapped yarn is increased. It is principally employed for elastic fabrics for instance leg guards, elastic belts, sock openings and tights.

Along with the spandex extend necessity in ACY, SCY has An additional vital approach parameter will be the twist. Twist will make a big difference in quality, elongation and evenness. Improve the twist to raise the pressure of holding among the outer masking fibre and the spandex yarn, creating the covering yarn more robust.

Even though SCY has decrease Main publicity, frequently not as likely to cause high quality problems in spinning and weaving, aside from uneven twists, on the other hand, its output effectiveness is small. So, the price is more than RMB 5000/T greater than exactly the same regimen of ACY. The price of FDY is much more than RMB 10000/T greater than exactly the same schedule of ACY. Consequently it greatly increases the expense of utilizing the SCY.

At Herng Fa, our SCY can be tailored to meet unique client needs. The customization selections consist of deciding upon different key yarns (including purposeful yarn or color yarn) and matching yarns (useful yarn) to make exclusive SCY with either S or Z twists. The Z twist includes a clockwise turn, even though the S twist is usually a counterclockwise change.

By utilizing differing types of wrapping resources and approaches, the Spandex Main is properly-secured through washing, which extends The material's lifespan.

One covered yarn entails wrapping an individual layer of masking yarn around a core yarn, commonly spandex. This method results in a yarn that provides reasonable elasticity and toughness, making it ideal for a range of purposes.

Herng Fa's advanced engineering permits us to customise the primary and matching yarns In line with your unique specifications, making certain a customized Alternative for the textile wants.

One-covered yarn is often a core spandex outer layer wrapped with an outer covering yarn, with fairly much less wrapped circles, the spandex core may check here perhaps expose in the final cloth.

In this sort, the Spandex Yarn is to start with covered with Polyester or Nylon DTY in a spiral wave with S twist & then on top of it, the yarn is again covered with Polyester or Nylon DTY inside a spiral wave with Z twist.

The elongation of your SCY is usually predominantly based on the effectiveness with the spandex Main yarn twisting excessive, the outer layer of fibre wrapped also closely, and the elastic outcome of your spandex yarn can’t give a fantastic functionality so the elongation decreases.

It doesn’t adapt to make deep colour products and solutions, it’s generally employed for socks, weft knitted underwear along with other stretch weaving.

Spandex-covered yarn is especially utilized for fabrics that desire high elasticity and partly for woven fabrics. The fabric woven with masking yarn is thicker and especially suited to weaving sports limited. Like swimming fits and ski satisfies.
