改性聚酯纤维的减量处理工艺研究

Study on deweighting technology of modification polyester fiber

考察了氢氧化钠水溶液、乙二胺水溶液和氢氧化钠与乙二胺的混合水溶液被用来处理纤维时,处理温度和处理时间对改性聚酯纤维减量率的影响,发现氢氧化钠水解速率大于乙二胺的氨解速率,氢氧化钠和乙二胺对改性聚酯纤维有协效作用。

Sodium hydroxide solution, diamine solution and mix solution of sodium hydroxide and diamine was used to treat the modification polyester fiber. The effect of parameters such as treatment time and temperature on the mass loss of modification polyester fiber has been studied in above solution. The result showed that sodium hydroxideg hydrolyze rate was larger than diamineg ammonolysis and coordinated effect on the modification polyester fiber occurred between sodium hydroxide and diamine.
