摘　　要：为解决高比例涤纶与粘胶混纺纱纤维间抱合力较弱,受摩擦力作用纤维间容易产生滑移从而产生棉球的问题,应用NY-6结构化变性淀粉设计了两种配方进行上浆实践。通过测试和对比两种配方的浆液流变性能、浆纱效果和浆纱毛羽,并应用电子显微镜对浆纱浆膜被覆情况及磨断口附近的纱线状态进行观察,认为采用NY-6结构化变性淀粉能有效提高浆纱质量,并能大幅度替代PVA的用量。To resolve problem of weak cohesion between high ratio polyester and viscose fiber and more cotton balls generating by fibers friction, two kinds of formula was tested by applying NY-6 structural modified starch. Through test and comparing size theological property, sizing effect and sizing hairiness, size film coverage and yarn state in breakage area was observed through electronic microscope. The result shows that adopting NY-6 structural modified starch can improve sizing quality, and instead of PVA considerably.
