摘　　要：依据少用或不用PVA浆料的原则,选择PR-S浆料取代PVA进行浆纱试验,采用二次回归正交设计的方法,制定浆液配方,分别对纱线进行上浆。根据实际生产对浆纱质量的要求,对上浆纱的断裂强度、断裂伸长率、耐磨性及毛羽指数等指标进行测试。利用模糊数学的方法对测试结果进行分析,得到上浆纱的综合性能评价值。结果表明:PR-S取代PVA时,当PR-S与PVA的用量比值在1.4∶1左右时,上浆纱综合性能较好,尤其是耐磨性与毛羽贴伏效果均较好。According to the request for using less or nonusing PVA,PR-S size was selected and sizing test was conducted with PR-S size replacing PVA.The method of quadratic regression orthogonal design was adopted in working out sizing instruction.Sizing experiments were carried out.According to the quality requirements of sized yarns in practical production,the properties of the sized yarns such as breaking strength,breaking elongation,wear resistance and hairiness index were tested.The testing results were analyzed by fuzzy mathematics and evaluation of comprehensive performance of the sized yarns was obtained.It was found that better comprehensive performance of the sized yarns was achieved when using PR-S size replacing PVA or mixed size of PR-S and PVA（about 1.4∶ 1）,especially the wear resistance and hairiness reduction.
