N_2等离子体接枝处理丙纶改性及染色的初步研究(英文)

Polypropylene Fiber Surface Modification via Nitrogen Plasma Pretreatment & Grafting and Subsequent Dyeing

丙纶纤维具有显著的物理化学优点,但丙纶纤维染色困难制约了其应用与发展。本研究用氮气等离子体对丙纶纤维进行表面处理,然后用丙烯酸接枝丙纶纤维。用傅立叶变换红外光谱和扫描电镜分析改性前后样品。结果表明:等离子体表面处理接枝后的丙纶纤维能染上鲜艳的阳离子艳兰。

Polypropylene （PP） fiber has outstanding physical and chemical advantages, but it is very difficult to be dyed so PP fiber＇ s applications are greatly restricted. We have here studied the methods to ameliorate the dyeing property by nitrogen （ N2 ） plasma pretreatment and acrylic acid grafting. Its surface chemical composition was changed after plasma treatments and was characterized by Scanning Electronic Mirror -SEM, Fourier Transformed Infrared Spectra -F＇FIR accordingly. The results show that the fiber＇s surface after treatment could been dyed by basic blue 54 dyestuffs.
