摘要
论述了用表面活性剂对纺粘法丙纶非织造布进行亲水化改性的机理和表面活性剂的选用要求。通过正交试验法优选出用三组分表面活性剂复配体系对丙纶非织造布整理的最优工艺条件 ,讨论了处理温度、处理时间和处理浓度对非织造布亲水性影响的规律。经整理后的纺粘法丙纶非织造布的透水时间为 1 .2s。
In the paper, the principle of improving water absorbability of polypropylene spunbond nonwovens by surfactants and the demand of the selection of surfactants are discussed. After achieving the optimal conditions in hydrophilic finishing of polypropylene nonwovens by ternary component compound surfactants through the diagonal intersection law, the rule of the influence of changes of all conditions, such as finishing temperature, finishing time and consistency of the surfactants, on hydrophilicity of polypropylene spunbond nonwovens is discussed. The water-penetrating time of the finished polypropylene nonwovens is 1.2s, which proves that the excellent modified effect of hydrophilicity is achieved.
