摘要
为适用市场需求,常规的半消光PET产品供大于求。为争夺市场,开发的全消光PET直纺产品占据了市场先机,由于全消光产品中添加的消光剂TIO2是半光产品的10倍,外加辅剂量偏多,熔体输送过程中温升大,降解多,后纺的满卷率一直不高,本文主要探讨了通过增加熔体冷却器,降低熔体温度,减少熔体在输送过程的粘度下降,来提高后纺的满卷率。
market demand for the application of conventional semi-dull PET product oversupply. Competition for the market, the development of full dull PET spinning products occupy the market opportunities, as dull products added matting agent is 10 times TIO2 semi-gloss products, plus auxiliary dose ones, the melt temperature during transport large degradation and more, after spinning full volume rate has been low, the paper discusses the melt by adding cooler, lower melt temperature and reduce the melt viscosity of the delivery process of decline, after spinning full volume to increase rates.
