Staple-covered yarn is preprocessed by one or more yarns patched together after which you can twisted about the spool by a twisting device. both of those the covered yarn plus the outer covering yarn can be viewed.
The double-covered yarn has two outer layers of filaments or yarns wrapped round the spandex Main, and these two layers are commonly in reverse directions. The core spandex is covered to a superb extent as well as core exposure is considerably less, and since the outer wrapped filaments are wrapped with opposite spiral angles symmetrically across the core filaments, the elasticity with the wrapped yarn is perfectly balanced and may normally be processed from the afterwards process with out shaping remedy, although the processing expense of double wrapped yarn is bigger. It is mainly used for elastic fabrics like leg guards, elastic belts, sock openings and tights.
Together with the spandex stretch need in ACY, SCY has One more crucial process parameter could be the twist. Twist might make a distinction in high-quality, elongation and evenness. Raise the twist to raise the pressure of holding concerning the outer covering fibre as well as spandex yarn, generating the covering yarn more robust.
Air-covered yarn, the outer fibre filament and spandex yarn are drawn through a particular style of nozzle at the same time. Soon after superior pressed air is frequently sprayed to sort a daily network of factors while in the yarn. The material feels gentle and easy.
At Herng Fa, our SCY may be get more info custom made to satisfy particular customer desires. The customization alternatives consist of deciding upon distinct main yarns (for instance functional yarn or coloration yarn) and matching yarns (functional yarn) to develop special SCY with possibly S or Z twists. The Z twist requires a clockwise transform, although the S twist is usually a counterclockwise flip.
By utilizing differing types of wrapping resources and approaches, the Spandex Main is very well-shielded all through washing, which extends The material's lifespan.
Solitary covered yarn involves wrapping an individual layer of masking yarn about a Main yarn, typically spandex. This process ends in a yarn that offers reasonable elasticity and energy, rendering it ideal for several different applications.
Herng Fa's Innovative technological know-how enables us to personalize the most crucial and matching yarns In accordance with your precise requirements, making certain a customized Alternative for the textile demands.
Solitary-covered yarn is a Main spandex outer layer wrapped using an outer masking yarn, with reasonably fewer wrapped circles, the spandex Main could expose in the ultimate material.
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 inside a spiral wave with Z twist.
The elongation on the SCY is likewise generally based on the functionality on the spandex core yarn twisting excessive, the outer layer of fibre wrapped also carefully, and also the elastic impact from the spandex yarn can’t give a good performance so which the elongation decreases.
Herng Fa's procedure is particularly noteworthy for its overall flexibility, given that the matching yarn and the two primary yarns might be modified In keeping with specific consumer demands.
It doesn’t adapt to make deep colour products, it’s predominantly employed for socks, weft knitted underwear and also other stretch weaving.
Spandex-covered yarn is mainly useful for fabrics that need superior elasticity and partly for woven fabrics. The fabric woven with masking yarn is thicker and especially well suited for weaving sports activities limited. Including swimming satisfies and ski suits.
