泡沫上浆与经纱预湿协同工艺的浆纱效果

Sizing effects of foam-sizing and warp pre-wetting combined process

针对传统上浆方法存在浆料消耗多、能耗高等问题,研究了泡沫上浆-经纱预湿协同上浆新工艺,并将其与传统上浆方法进行了比较。通过对比传统浆纱工艺与经纱预湿-泡沫上浆协同工艺在纱线的质量指标、纱线形态和织造效率上的差异,揭示新工艺方法的优越性。实验结果表明,泡沫上浆-经纱预湿浆纱工艺在纱线增强率、减伸率、耐磨提高率、毛羽降低率等质量指标以及织造效率方面与传统浆纱工艺相近,但其上浆率明显低于传统上浆方式,而且在节省蒸汽能耗,降低退浆废水排放量以及节省退浆助剂方面有明显优势。

Aiming at overcoming the drawbacks in traditional sizing process,such as high energy consumptions and sizing-agent cost,this research explored a new sizing approach by combing the foamsizing and warp pre-wetting processes.Through the comparison tests on sizing quality,yarn morphology,and weaving efficiency between the traditional sizing process and this combined process,it is proved that the combined process is superior.In comparison with the combined process and the traditional sizing process,the sizing yarn qualities,such as the strength increase rate,the elongation decrease rate,the wear resistance increase rate and the hairiness decrease rate,are in the same level,and the weaving efficiency are not affected significantly with the new process.The combined process is superior to the traditional process in the saving of gas,desizing waste water and desizing agent.
