海藻纤维柔软机理模型的初步研究

用实验室自制柔软剂对海藻纤维进行后处理。利用傅里叶红外光谱仪(FT-IR)、扫描电子显微镜(SEM)、X-射线能谱仪分析(XPS)、透射电镜(TEM)分析基体表面官能团的分布、表面形貌、柔软剂在纤维内部的分散状况以及柔软剂微乳液的破乳状况。结果表明:柔软剂分子破乳后从胶束中溢出,在海藻纤维表面产生定向吸附,在纤维表面形成光滑的膜层,并渗透到海藻纤维内部,赋予纤维优良的柔软性能。

Preliminary Study on the Softeness Mechanism Model of Alginate Fiber

The softener self-made at laborotary is used to treat the alginate fiber.The FT-IR,SEM,XPS and TEM are applied to analyze the treatmented samples,and the functional groups,surface morphology of the surface of substrates,the penetration of softener molecules and the demulsification of softener microemulsion are obtained.The results show that softener molecules escape from micelle and adsorb on the surface of the alginate fiber regularly forming the smooth film,softener molecules penetrate into the alginate fiber and endow the alginate fiber with the softness.
