发明名称 MANUFACTURING METHOD OF POLYESTER AIR TEXTURED YARN HAVING EXCELLENT THERMO-KEEPING PROPERTY AND BEING LIGHTWEIGHT
摘要 PURPOSE: A manufacturing method of polyester air textured yarn is characterized by controlling pneumatics properly in air-texturing, not passing through a heat setting process and reducing a change of hollow ratio of hollow fiber. The polyester air textured yarn is characterized by having excellent thermo-keeping property and being lightweight. Drawn polyester fiber is capable of weaving textile having soft touch. CONSTITUTION: Polyester air textured yarn is obtained by: preparing polyester hollow fiber as core yarn; preparing drawn polyester fiber as sheath yarn; and then air-texturing the fibers with 6-9bar of pneumatics. A discharge velocity of the air textured yarn is 350-400m/min.. Over feed ratio of the sheath yarn on the core yarn is 10-12%. Single fineness of the drawn polyester fiber is 0.3-0.6denier.
