It should be exclusively adjusted based on the use tone as well as the variety of its downstream fabric.
As well as the spandex stretch prerequisite in ACY, SCY has Yet another important course of action parameter may be the twist. Twist can make a variance in top quality, elongation and evenness. Enhance the twist to boost the drive of holding between the outer covering fibre and the spandex yarn, generating the masking yarn more powerful.
While SCY has lessen Main publicity, generally less likely to result in good quality troubles in spinning and weaving, apart from uneven twists, on the other hand, its output performance is reduced. Consequently, the worth is in excess of RMB 5000/T higher than exactly the same regime of ACY. The price of FDY is a lot more than RMB 10000/T bigger than the identical program of ACY. Thus it greatly increases the expense of using the SCY.

Solitary covered yarn will involve wrapping just one layer of masking yarn all-around a core yarn, normally spandex. This method brings about a yarn that offers reasonable elasticity and energy, rendering it suitable for many different apps.
Herng Fa's State-of-the-art technologies allows us to customise the main and matching yarns In line with your unique specifications, making certain a customized Alternative for the textile wants.
One-covered yarn is often a core spandex outer layer wrapped having an outer covering yarn, with relatively less wrapped circles, the spandex core may well expose in the final cloth.
