When the program spandex yarn is pre-drawn three.5 periods, the creep resistance is very best. It ought to be specifically modified in accordance with the usage tone plus the type of its downstream material.

Once the ACY warps on the air jet loom, ordinarily need to have sizing, in any other case The material is a snap to lint, break and the like, but weft is can directing use. Just look at Expense, ACY is a lot more effective than SCY, and it can have a lower cost than SCY, therefore decreasing the downstream factories’ Expense.
