摘要
研究了驱蚊剂、分子量调节剂对母粒的可纺性的影响,探讨了驱蚊丙纶纤维中驱蚊剂释放速率、驱蚊效果以及驱蚊纤维对人体健康影响的表征方法。研究结果表明:驱蚊剂A和驱蚊剂B适合用作驱蚊纤维的添加剂,其中驱蚊剂A更为理想;驱蚊剂的加入可以提高母粒的熔体流动速率,但还需加入3％分子质量调节剂,才能从根本上改善母粒的可纺性,实现高速纺丝。利用紫外光谱法测定两种驱蚊剂的半衰期,结果驱蚊剂A的保留时间远高于驱蚊剂B。毒性试验表明,研制的驱蚊纤维长期使用对人体健康无危害。
The effect of mosquitos repellent and molecular weight regulator on spinnability of masterbatch was studied. The characterizing methods for mosquitos repellent releasing speed, insect repelling result, and effect of mosquitos - repelling fiber on human health were also discussed. The research result showed that the dosing of mosquitos repellent could increase the melting index of masterbatch, but the spinnability of masterbatch couldn' t be improved radically and high - speed spinning couldn' t be realized until 3% molecular weight regulator was dosed. The toxicity test showed that long - term using of this mosquitos - repelling fiber was not harmful to human health.
