碱减量对涤纶亲水性改性影响的研究
|
摘要
为解决涤纶吸水性差、回潮率低、易起球、抗油污性能差及存在极光等问题,本文对涤纶进行了改性研究。以碱减量作为主要指标,研究了促进剂用量、Na OH浓度、碱减量时间、温度、浴比等对涤纶亲水性的影响。实验结果表明:当温度为100℃、浴比为1︰50、时间1 h、碱浓度为10 g/L、1227促进剂用量为总溶液的0.06%时,效果最佳;经过碱减量处理后,对涤纶表面的剥蚀作用增强了涤纶毛细管原理,吸水性明显增加。
In order to solve the problems of poor water absorption, low moisture regain, easy balling, poor oil-resistance and aurora, the research on the modification of terylene is carried out. Taking alkali reduction as the main index, the effects of dosage of accelerator, concentration of sodium hydroxide, reaction time, temperature and bath ratio on the hydrophilicity of polyester were studied. Experimental results show that when the temperature is 100 ℃, bath ratio is 1︰50, reaction time is 1 h, alkali concentration is 10 g/L, and the dosage of 1227 accelerator is 0.06 % of total solution, the effect is best. After alkali reduction. The denuding effect on the polyester surface enhances the principle of the polyester capillary, and the water absorption increases significantly.
