摘要/Abstract

摘要： 为了提高退浆效率及环保性，利用常压等离子体射流与传统碱退浆相结合去除涤纶面料上的聚丙烯酸酯浆料。重点研究了等离子体处理时间对退浆效果的影响和等离子体预处理对湿退浆效果的影响。此外，还研究了等离子体处理对浆膜表面化学成分的影响。X射线光电子能谱仪（XPS）结果表明，经等离子体预处理后，浆膜表面的含氧基活性基团的数量明显提高，增强了浆膜的亲水性。退浆率（PDR）结果表明随着等离子体处理时间的延长，退浆效果明显提高。经等离子体预处理65s后，再进行5min的NaHCO3退浆，退浆率可达到99%以上。与传统湿退浆相比，等离子体处理能够显著减少退浆时间。

Abstract: In order to improve the desizing effect and environmental protection, the polyacrylate size agent was removed from PET fabrics by the combination of He/O2 atmospheric pressure plasma jet (APPJ) and conventional wet desizing. The influence of plasma treatment time on desizing effect and the influence of plasma pre-treatment on wet desizing effect were studied. And the influence of plasma treatment on the chemical components on the size film surface was also studied. The results of XPS analysis indicate that oxygen-based functional groups increased for the plasma treated polyacrylate sized fabrics, which greatly improve the hydrophilcity of polyacrylate film. The percent desizing ratio (PDR) results show that with an increase of plasma treatment time, the desizing effect is significantly improved. More than 99% PDR was achieved after 65s plasma treatment followed by a 5min NaHCO3 desizing. Compared to conventional wet desizing, plasma treatment could significantly reduce desizing time.
