半光涤纶FDY切片含水率对长丝质量及面料性能的影响

Study on Effect of Moisture Content of Semi-Gloss Polyester FDY Chips on Filament Quality and Fabric Properties

为改善长丝面料的平整度与色差问题,从长丝原料出发,采用单因素法探讨了聚酯切片含水率对长丝断裂强度、条干均匀度以及织物面料的影响。实验表明:在纺制22. 2 tex/48F半光涤纶FDY的过程中,切片含水率为30 mg/L时,涤纶FDY的断裂强度和条干均匀度为最佳,即长丝质量达到最优;为保证切片含水率在30 mg/L,干燥温度和干燥时间分别为135℃与4 h最合理。用半光涤纶FDY织造的面料布面平整光滑,染色后无色档,优于市场上同规格产品,具有一定的市场应用价值。

In order to improve the flatness and color difference of fabrics made by filament,the influence of moisture content of polyester FDY chips on the breaking strength,evenness and fabric properties was studied by single factor method.The experimental results showed that:in the spinning process of 22.2 tex/48F semi-gloss polyester FDY,when the moisture content of chips is 30 mg/L,the full-package rate of polyester FDY is the best.The breaking strength and evenness of polyester FDY are the best,that is,the quality of filaments is the best.In order to ensure 30 mg/L moisture content for chips the drying temperature and drying time are most reasonable at 135℃and 4 h,respectively.The fabrics woven with these filaments have smooth surface and no color file after dyeing,which is superior to the same specification products on the market and has certain market application value.
