【摘要】 研究了乙二胺对涤纶碱水解的影响。结果表明,涤纶碱水解时添加乙二胺,不仅可以提高涤纶碱水解速率,同时可以使涤纶表面产生较深的裂纹和凹槽,从而为涤纶的丝素涂膜整理打下基础。更多还原

【Abstract】 The effect of ethylenediamine on the alkaline hydrolysis of polyester fibers is studied. The result showed when ethylenediamine was added to the alkaline treatment bath of PET fibers, the rates of the alkaline hydrolysis increased considerably. Meanwhile, many elongated pits formed on the fiber surfaces. Thus, the coating finish of silk fibers onto polyester fiber can be possible.更多还原
