By expanding the spandex stretch, the percentage content of spandex yarns will lessen and lead to a significant degree of curl within the wrapped fibres. Even so, if the diploma of extend is simply too big, the spandex yarn deformation amplitude is close to the crucial value of deformation.

The elongation in the SCY is additionally mostly determined by the overall performance from the spandex core yarn twisting too get more info much, the outer layer of fibre wrapped much too intently, plus the elastic influence in the spandex yarn can’t give an excellent overall performance so that the elongation decreases.
Herng Fa's procedure is particularly notable for its overall flexibility, as being the matching yarn and The 2 main yarns can be adjusted In accordance with distinct purchaser necessities.
It doesn’t adapt to produce deep colour goods, it’s mainly useful for socks, weft knitted underwear and also other stretch weaving.
