摘要
以甲基丙烯酰氧乙基三甲基氯化铵(DMC)和二甲基二烯丙基氯化铵(DMDAAC)为单体,水相溶液聚合制备P(DMC-DMDAAC),通过红外光谱(IR)分析合成产物表明,得到了所需分子结构的产物。将合成产物作为促进剂应用于涤纶碱减量处理,通过单因素分析,研究了碱减量温度、促进剂质量浓度、氢氧化钠质量浓度对涤纶碱减量处理效果的影响。优化的工艺条件为:碱减量温度130℃,促进剂质量浓度0.6 g/L,氢氧化钠质量浓度10 g/L。扫描电子显微镜(SEM)观察碱减量处理前后涤纶纤维表面形貌,发现纤维表面的确发生了"剥蚀"现象。
P （DMC-DMDAAC） was prepared via water-phase solution polymerization through taking methacrylatoethyl trimethyl ammonium chloride （DMC） and dimethyl diallyl ammonium chloride （DMDAAC） as the monomer. The synthetic product was analyzed with infrared spectrum （IR）. It was found that the product with the desired molecular structure was gained. The synthetic product as an accelerant was applied in alkaline deweighting for polyester fabrics. The effects of alkaline deweighting temperature, mass concentration of the accelerant and mass concentration of sodium hydroxide on the effects of alkaline deweighting were studied through single factor analysis. The optimal technological conditions were ： alkaline deweighting temperature 130 ~C, mass concentration of the accelerant 0.6 g/L, mass concentration of sodium hydroxide 10 g/L. Through observing surface appearance of polyester fiber before and after alkaline deweighting with SEM, it was found chemical denudation＂ phenomenon indeed occurred on the surface of the fiber.
