摘要
将耐候性油剂TF-7716NH应用于熔体直纺涤纶预取向丝(POY)-假捻变形丝(DTY)的生产,并将POY置于室外密闭环境连续存放90 d,测试POY的含油率、POY-DTY加工性能,研究了油剂TF-7716NH的基本应用性能和耐候特性,并与进口油剂L165M和F-3788的性能进行对比。结果表明:使用TF-7716NH油剂生产的涤纶POY的优等品率,以及经过POY-DTY加工所得DTY的满卷率、染色M率和优等品率均能完全达到使用进口油剂生产的产品质量水平;使用TF-7716NH油剂生产的POY在经过70℃、168 h的连续放置后,其含油损失率仅2.9%,POY置于室外连续放置90 d仍能保持优良的可加工性能;TF-7716NH油剂表现出明显优于进口油剂的耐候特性,在涤纶POY-DTY工艺中完全可替代进口油剂L165M和F-3788。
The weather-resistant spinning finish TF-7716NH was applied to the production of melt spun polyester pre-oriented yarn(POY)-draw textured yarn(DTY),and the POY was stored in an outdoor closed environment for 90 d.The oil content of POY and the processing performance of POY-DTY were tested.The basic application performance and weather resistance of spinning finish TF-7716NH were studied and compared with those of imported spinning finishes L165M and F-3788.The results showed that the high-quality rate of polyester POY produced with spinning finish TF-7716NH and the full package rate,dyeing M rate and high-quality rate of DTY fabricated by POY-DTY process can fully reach the product quality level produced using imported spinning finishes;the oil loss rate of POY produced using spinning finish TF-7716NH was only 2.9%after continuous storage at 70℃for 168 h and the POY can still maintain excellent processability after continuous outdoor storage for 90 d;and spinning finish TF-7716NH was superior to imported spinning finishes in weather resistance and can completely replace imported spinning finishes L165M and F-3788 in polyester POY-DTY process.
