Staple-covered yarn is preprocessed by a number of yarns patched with each other and then twisted over the spool by a twisting device. each the covered yarn and the outer masking yarn may be found.
Herng Fa prides by itself on skills in covered yarn production, giving prime-notch excellent and Fantastic performance. Our various variety consists of standard covered yarns and progressive air-covered yarns, all tailor-made to meet your distinctive specifications. With our commitment to excellence and customer gratification, we be certain you get only the ideal.
Together with the spandex stretch need in ACY, SCY has One more essential system parameter would be the twist. Twist could make a change in good quality, elongation and evenness. Increase the twist to boost the force of Keeping in between the outer masking fibre and also the spandex yarn, earning the covering yarn much better.
Nevertheless SCY has lower core exposure, typically more unlikely to lead to excellent complications in spinning and weaving, except for uneven twists, however, its manufacturing efficiency is minimal. Hence, the value is a lot more than RMB 5000/T increased than the exact same regime of ACY. The cost of FDY is more than RMB 10000/T better than the exact same program of ACY. For that reason it drastically boosts the price of using the SCY.
At Herng Fa, our SCY may be custom made to satisfy specific purchaser wants. The customization options include things like picking different major yarns (like purposeful yarn or colour yarn) and matching yarns (purposeful yarn) to build one of a kind SCY with both S or Z twists. The Z twist involves a clockwise convert, whilst the S twist is often a counterclockwise flip.
By making use of different types of wrapping materials and solutions, the Spandex core is well-safeguarded through washing, which extends The click here material's lifespan.
One covered yarn entails wrapping one layer of masking yarn around a core yarn, commonly spandex. This process leads to a yarn that gives average elasticity and strength, rendering it suitable for various applications.
Herng Fa's advanced technological innovation permits us to customize the principle and matching yarns In keeping with your particular necessities, making sure a tailored Resolution in your textile needs.
One-covered yarn can be a core spandex outer layer wrapped having an outer covering yarn, with fairly much less wrapped circles, the spandex core may perhaps expose in the final fabric.
In this type, the Spandex Yarn is initial covered with Polyester or Nylon DTY within a spiral wave with S twist & then along with it, the yarn is once again covered with Polyester or Nylon DTY in the spiral wave with Z twist.
The elongation of the SCY is also primarily determined by the performance of the spandex Main yarn twisting too much, the outer layer of fibre wrapped much too intently, plus the elastic influence on the spandex yarn can’t give a superb efficiency so that the elongation decreases.
Herng Fa's approach is especially noteworthy for its flexibility, because the matching yarn and the two major yarns is often altered according to particular client demands.
It doesn’t adapt to produce deep colour items, it’s primarily used for socks, weft knitted underwear and various extend weaving.
Spandex-covered yarn is especially utilized for fabrics that demand from customers substantial elasticity and partly for woven fabrics. The fabric woven with covering yarn is thicker and particularly appropriate for weaving sports restricted. Such as swimming fits and ski satisfies.
