Method for producing warp knitting coral velvet polyester filament yarn
InactiveCN101476188AAdjustable fine structureFine structure stabilityTextiles and paperHot boxEngineering
The invention provides a method for producing warp knitting coralon leather polyester filament. The processed POY protofilament is removed to false twist after being detected and balanced, the process flow is that: POY protofilament - a roller feeding in - a hot box for heating distortion - cooling - false twist - two rollers feeding in - two hot boxes for heating and forming - three rollers feeding out - oiling - DTY winding forming, a pre-network working procedure is added between the ROY protofilament and a roller feeding in. The method solves problem that coralon leather fabric processed by normal polyester has defects of no-soft hand touch, adhesive hair, down pile making, without coralon leather style, and can cover the prior art shortage.
