摘要
针对当前传统上浆能源消耗大的现状,为降低能源消耗和浆纱成本,以水分散性聚氨酯丙烯酸酯、光引发剂Darocur1173、甘油、等离子水为主要原料,利用UV光固化的方法实现对纱线的上浆。对原纱的性能、光固化溶液的黏度、黏度稳定性、黏附性以及光固化后的纱线质量等性能进行测试,以探讨用光固化技术替代传统上浆的可行性。研究结果表明:溶液黏度波动小、热稳定性较好;光固化后原纱的断裂强力提高54.77%,断裂伸长率提高46.70%;毛羽指数大大降低,毛羽降低率为62.45%;耐磨性大大提高,耐磨倍数提高近5倍。可见利用光固化技术实现对纱线的上浆是可行的。
Based on the huge energy consumption of traditional sizing, in order to reduce energy consumption and sizing cost,water-dispersible polyurethane acrylate, photoinitiator darocur 1173, glycerin and plasma water are used as main raw materials to apply to yarn sizing with UV light curing method. The properties of the original yarn, viscosity of light curing solution, viscosity stability, adhesion and yarn quality after light curing are tested to discuss the feasibility of replacing traditional sizing with light curing technology. The results show that the viscosity fluctuation is small and the thermal stability is good. After light curing, the breaking strength of the original yarn increases by 54.77%, the elongation at break increases by 46.70%, the hairiness index greatly reduces with a reduction rate of 62.45%, and the wear resistance also greatly can be improved by nearly 5 times. It is feasible to realize yarn sizing with light curing technology.
