摘　　要：纺织经纱上浆中常用的浆料主要有淀粉、PVA、丙烯酸类三大类。PVA解决了上浆中的渗透、成膜问题,但增加了印染前处理时的退浆难度,并且污染环境。新型改性淀粉浆料生产与替代PVA应用关键技术的出现,减轻了前处理退浆难度,降低了工艺温度,缩短工艺流程时间,具有节能优势,并有助于提高印染的一等品率。Starch,PVA and acrylic polymer are the main three sizes used in starching warp.PVA has the benefit of avoid permeation and film forming,but it is unfavorable to desizing process and causes pollution.Production of modified starch size and key technology for PVA substitution have the advantages of reducing the difficulty of desizing,wakening process conditions,shortening process time,and improving the first-class product rate of dyeing and printing.
