PREPARING PROCESS FOR COMPLEX DRAWING TEXTURED YARN HAVING IMPRESSING HEMP

摘要

The polyester finished yarn is made by pre-untwisting yarn obtained from partially oriented polyester yarn(POY). The pre-untwisting yarn has a filament fineness of grey yarn in the range of 1.6= d.p.f= 3.4 and a draw ratio of 1.250= D/R= 1.450, which is passed through the first heater at 220-247 deg.C and second heater at 190-230 deg.C to give the finished yarn. The finished yarn has a good shari feeling.
