聚乙烯乳液柔软剂的进展

制备聚乙烯（PE）乳液柔软剂的方法有乙烯乳液聚合、高压聚乙烯的裂解和氧化、高压聚乙烯直接氧化和氧化聚乙烯的乳化四种。聚乙烯乳液的离子型取决于所用乳化剂的离子属性,一般使用非离子乳化剂。PE乳液产品的浓度国外一般为 20～25％,国内通常为18％。PE乳液可与各种阴、阳离子助剂、柔软剂同浴使用,不发生对抗性沉淀,在后整理中,绝大多数与其他柔软剂复配混合作用。

Progress in Polyethylene Emulsion Softener

To prepare polyethylene(PE) emulsion,four ways can be applied. These are ethylene emulsion polymerization, polyethylene splitting and oxidation under high pressure,direct oxidation of polyethylene under high pressure and oxidated polyethylene emulsification. The ionic type depends on the ionic properties of the emulsions. Non-ionic emulsion was usually used. Generally,the PE emulsion concentration is 20-25% at abroad, 18% in domestic. PE emulsions can be used together with different anion,cation auxiliaries and softeners in one bath without antagonism deposition. Most of PE emulsions can be used with other softeners in post-treatment process of fabric.
