They are really compatible with other resources, and may be spun with other types of fibers to supply distinctive fabrics, that have attributes of the two fibers.
Nevertheless SCY has decreased Main exposure, usually less likely to bring about good quality problems in spinning and weaving, except for uneven twists, nevertheless, its production performance is very low. As a result, the price is a lot more than RMB 5000/T greater than a similar regimen of ACY. The price of FDY is much more than RMB 10000/T better than the identical plan of ACY. As a result it greatly enhances the cost of using the SCY.

The final twist level is modified read more in accordance with the variety of deniers of your yarn as well as the design and style needs of The material.
Additives will have to also be added. Every one of the stabilizers which have been added for the spandex fibers are intended to be immune to solvent publicity since this could have a harmful effect on the fiber.
