Once the plan spandex yarn is pre-drawn 3.five occasions, the creep resistance is most effective. It should be specially adjusted in accordance with the usage tone plus the type of its downstream material.
In combination with the spandex extend requirement in ACY, SCY has A further significant method parameter is the twist. Twist will make a variation in high quality, elongation and evenness. Enhance the twist to boost the drive of holding between the outer masking fibre and also the spandex yarn, building the covering yarn much better.
Although SCY has reduced Main publicity, typically more unlikely to bring about high-quality issues in spinning and weaving, aside from uneven twists, having said that, its output performance is very low. So, the price is greater than RMB 5000/T larger than precisely the same regime of ACY. The cost of FDY is more than RMB 10000/T bigger than the same routine of ACY. Consequently it significantly raises the cost of utilizing the SCY.
At Herng Fa, our SCY is usually custom-made to meet precise client needs. The customization selections contain selecting unique primary yarns (which include practical yarn or coloration yarn) and matching yarns (practical yarn) to develop special SCY with possibly S or Z twists.

Lowering our footprint But sneaker/trainer footprints are arguably less significant than our personal (carbon) footprint. Plus the clever know-how has helped us produce a significant effect there far too.
Our expense in the division has authorized us to produce a enormous suite of sustainable answers such as 100% bio-degradable yarns for disposable merchandise– which decompose in a lot less than 3 many years; lessened h2o use in dope-dyed and Room-dyed yarns; and 100% dry functions – which indicate we discharge Completely no nasty substances to the atmosphere.
Double covered yarn features a spandex Main that is enveloped by two key yarns twisted in opposite Instructions—one while in the Z twist (clockwise) and one other inside the S twist (counterclockwise). This twin-layer wrapping approach don't just enhances the sturdiness and elasticity of the yarn but in addition allows for different twist angles to build a number of material hand feels.
The elongation of the SCY is also mainly based on the performance of the spandex Main yarn twisting far too much, the outer layer of fibre wrapped much too intently, plus the elastic result in the spandex yarn can’t give an excellent efficiency so that the elongation decreases.
