It should be specially adjusted in accordance with the usage tone plus the type of its downstream material.
Parallel or textured polyamide yarns can be employed to generate the double go over. The double coated thread is used to make clothing, underwear and hosiery of top of the range and exceptional efficiency.
Although SCY has reduced Main publicity, commonly not as likely to cause excellent complications in spinning and weaving, except for uneven twists, nevertheless, its creation effectiveness is very low. So, the worth is much more than RMB 5000/T increased than a similar routine of ACY. The price of FDY is much more than RMB 10000/T bigger than the same schedule of ACY. Consequently it significantly raises the cost of using the SCY.
ACY and SCY have their advantages and disadvantages in downstream weaving factories. In the event the ACY warps about the air jet loom, commonly need to have sizing, in any other case the fabric is a snap to lint, split and so on, but weft is can directing use. Just take into consideration Value, ACY is more successful than SCY, and it can have a cheaper price than SCY, that's why lowering the downstream factories’ Charge.
