控制苎麻纱浆纱毛羽的技术措施

Technical Measures of Controlling the Hairiness of Ramie Yarn Sizing

为减少27.8tex苎麻纱浆纱毛羽,通过对比试验分析了双浸双压上浆工艺、上浆率、回潮率、浆料配方、湿分绞根数等工艺因素的影响,并优选出了合理浆纱工艺参数。结果表明选用低黏度、成膜性好的浆料,采用"高浓度,低回潮,高上浆,双浸双压、湿分绞"工艺路线,能显著降低上浆苎麻纱的毛羽,布机经纱断头率能降低到0.6根/台·h以下。

In order to reduce the hairiness of 27. 8 tex ramie sizing yarn, by comparison of test methods, the influences of the double dipping and double pressure technology, sizing percentage, moisture rate and size formula were studied. The reasonable tech- nology parameters were optimal selected. The experimental results showed that selecting size formula of low viscosity and good film, using high density, low return, high sizing, double dipping and double pressure, separating wet yarn sticks technology could signifi- cantly reduce yarn hairiness, and broken wrap rate could reduce to 0.6 roots per hour in a weaving machine.
