溶剂和添加剂对尼龙6鬃丝结构形态和道明性的脸响

THE INFLUENCE OF SOLVENT AND ADDITIVES ON STRUCTURE, MORPHOLOGY AND TRANSPARENCY OF NYLON 6 FILAMENTS

针对增加鱼网丝的透明性,各国都进行了大量的工作。一种措施是在生产尼龙6鬃丝的过程中,用不同的溶剂代替水作凝固浴,例如四氯化碳,氢氧化钠的水溶液,己烷,白油等。水的影响已引起人们的重视。另一种措施是在纺丝时向尼龙6切片中加入某种添加剂,例如氯化钠、十八烷基胺、硬脂酸锌共同使用,N。

The transparency of nylon 6 filaments is changed by spherulites formed by Solvent Induced Crystallization (SINC) in quenching bath. The long carbon chains in alkyl diamides additives can prevent Solvent (water) Induced Crystallization so that the transparency of nylon 6 filaments is improved. The nylon 6 filaments were examined by Scanning Electron Microscopy (SEM), Small-Angle Light-Scatting (SALS), polarized microscope, light transmission rate, contact angles and others.
