摘要
以十三氟辛氧丙基甲基二氯硅烷和二甲基二氯硅烷为原料,通过催化缩合制备了混合环硅氧烷,再加入四甲基二乙烯基二硅氧烷作为封端剂,通过开环聚合制备了3种不同氟含量的氟硅拒水整理剂,并以氢基硅油作交联剂应用于棉织物整理。通过红外光谱(FT-IR)和核磁共振(1H-NMR)表征了产物的结构,研究了整理剂的种类及用量对整理效果的影响。结果表明,该拒水整理剂对棉织物的拒水效果明显,当浓度为15 g/L时,拒水等级均可达到5级。与甲基有机硅整理剂相比,含氟有机硅整理剂整理后的棉织物具有更好的拒水性和耐洗性。
Mixed cyclosiloxane was prepared by catalytic condensation, with tridecafluorooctyloxa- propylmethyldichlorosilane and dimethyldichlorosilane as raw materials. Fluorine-containing silicone water-repellent finishing agent was prepared by ring-opening polymerization, with divinyl tetramethyl disiloxane as blocking agent. Three different fluorine content of fluorine-containing silicones were synthesized, and the hydrogen silicone as crosslinker was applied to water repellent finishing of cotton fabric. The structural properties of products were characterized by FT-IR and 1H-NMR. The effect of finishing efficiency on the type and amount of finishing agent was studied. The results show that the water-repellent effect of cotton fabrics is significant after finished with the water-repellent finishing agent. When the concentration is 15g/L, the water repellency rating can be up to five Level. Compared with the methyl silicone finishing agent, the water repellency and washability of the cotton fabric finished by the fluorine-containing silicone finishing agent are better.
