The higher the spandex stretch is, the upper the strength and elongation of ACY. Soon after stretching to a specific degree, the yarn retraction of spandex yarn would make the outer fibres appear curled. By rising the spandex extend, the percentage articles of spandex yarns will minimize and trigger a considerable diploma of curl within the wrapped fibres. Having said that, once the degree of extend is simply too big, the spandex yarn deformation amplitude is near to the important price of deformation. It'll lower the covered yarn's energy but is conducive to the covered yarn's uniformity.
In comparison to standard solitary-covered yarn solutions, air covered spandex yarn provides a more Charge-productive output process with out compromising on top quality.
in the event the twist is just too reduced, the outer masking fibre is usually free and affect the masking influence, which may cause the Main exposure, And so the twist must be higher in mechanical wrapping. However, if the twist is too significant, the fabric feels rigid and drapes poorly.

Herng Fa's Sophisticated technological know-how enables us to personalize the main and matching yarns In line with your specific needs, making certain a personalized Answer on your textile needs.

The elongation in the SCY can be generally based on the effectiveness with the spandex Main yarn twisting an excessive amount, the outer layer of fibre wrapped far too intently, plus the elastic influence with the spandex yarn can’t give a fantastic effectiveness so the elongation decreases.
Herng Fa's approach is especially noteworthy for its flexibility, since the matching yarn and The 2 principal yarns is usually adjusted In accordance with distinct purchaser requirements.
It doesn’t adapt for making deep colour solutions, it’s largely utilized for socks, weft knitted underwear and also other stretch weaving.
