The Ultimate Guide To double covered yarn

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

The double-covered yarn has two outer layers of filaments or yarns wrapped within the spandex Main, and these two layers are normally in reverse directions. The core spandex is covered to a good extent along with the Main exposure is less, and because the outer wrapped filaments are wrapped with reverse spiral angles symmetrically around the core filaments, the elasticity of your wrapped yarn is properly well balanced and may frequently be processed in the afterwards system without having shaping remedy, but the processing price of double wrapped yarn is higher. It is especially utilized for elastic fabrics for example leg guards, elastic belts, sock openings and tights.

In combination with the spandex extend requirement in ACY, SCY has A further significant method parameter is the twist. Twist may make a big difference in quality, elongation and evenness. Improve the twist to raise the pressure of holding involving the outer covering fibre as well as spandex yarn, producing the masking yarn stronger.

Even though SCY has decreased Main publicity, generally less likely to trigger top quality troubles in spinning and weaving, apart from uneven twists, on the other hand, its output performance is small. So, the worth is more than RMB 5000/T higher than exactly the same schedule of ACY. The price of FDY is much more than RMB 10000/T greater than exactly the same schedule of ACY. Therefore it greatly increases the expense of utilizing the SCY.

At Herng Fa, our SCY can be tailored to meet unique buyer needs. The customization options include picking out various most important yarns (including purposeful yarn or colour yarn) and matching yarns (purposeful yarn) to produce one of a kind SCY with either S or Z twists. The Z twist consists of a clockwise flip, when the S twist is really a counterclockwise switch.

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

Single covered yarn consists of wrapping a single layer of covering yarn all over a Main yarn, usually spandex. This process leads to a yarn that offers average elasticity and strength, which makes it suited to a variety of programs.

Herng Fa's Highly developed engineering permits us to customise the key here and matching yarns As outlined by your specific demands, making sure a tailored Answer on your textile requires.

One-covered yarn can be a core spandex outer layer wrapped by having an outer covering yarn, with rather less wrapped circles, the spandex core may possibly expose in the final cloth.

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

The elongation from the SCY can also be mostly determined by the overall performance from the spandex core yarn twisting too much, the outer layer of fibre wrapped much too intently, plus the elastic influence on the spandex yarn can’t give an excellent efficiency so that the elongation decreases.

Herng Fa's method is especially noteworthy for its adaptability, given that the matching yarn and the two primary yarns could be modified As outlined by unique customer specifications.

It doesn’t adapt for making deep colour merchandise, it’s mostly used for socks, weft knitted underwear and other extend weaving.

Spandex-covered yarn is principally used for fabrics that desire higher elasticity and partly for woven fabrics. The material woven with covering yarn is thicker and particularly suitable for weaving athletics tight. For example swimming suits and ski fits.
