预湿上浆机理的探讨

为了探讨预湿上浆的优越性,推广预湿上浆的应用,对预湿上浆的作用机理进行了分析.通过对比分析传统上浆方法与预湿上浆方法的浆纱毛羽、浆纱被覆与浸透情况,认为预湿上浆可增加浆料对经纱的黏附力、改善浆纱性能、降低上浆率,但预湿上浆对于浆液浓度和黏度的稳定性有一定影响,且预湿上浆工艺与纤维种类的关系有待于进一步深入研究.

Discussion of Pre-wetting Sizing Principle

To discuss the superiority and popularize application of pre-wetting sizing technology,its working principle was analysed.Through comparing and analysing effect of traditional sizing and pre-wetting sizing including sizing hairiness,sizing coverage and permeability,it is considered that pre-wetting sizing could increase adhesivity of size material to warp,improve sizing property,reduce sizing percentage,except effect sizing concentration and viscosity stability in a degree.Relationship between pre-wetting s...
