Improving the Production Technology of Bright Trilobal-Shaped Polyester FDY
When the melt direct spinning process is used to produce 44.4 dtex/72 f bright trilobal-shaped polyester fully draw yarn(FDY),there will be a typical problem-too much broken filaments.The formation mechanism of the broken filaments was analyzed,and the effects of the height of windless zone,the mass fraction of spin finish,the spin finish type and the drafting process on the broken filaments were discussed.The appropriate process conditions were found out by improving.
