摘要:

随着节能减排要求的提高及降低产品加工成本的需要,中低温浆纱技术受到越来越多关注,成为目前的研究热点。淀粉作为纺织浆料的主体,其中低温条件下水可溶是实现中低温调浆、上浆的关键。通过物理或化学变性的方法可赋予淀粉浆料中低温水溶性能。回顾了中低温水溶淀粉浆料制备方法及最新研究状况。着重介绍了中低温水溶淀粉浆料的物理制备方法和化学制备方法,分析了预糊化淀粉、颗粒状冷水可溶淀粉、羟丙基淀粉、羧甲基淀粉、磷酸酯淀粉及醋酸酯淀粉浆料制备方法的优缺点和关键制备工艺参数对其性能的影响,最后从中低温水溶性淀粉浆料制备过程的环保性角度对中低温可溶淀粉浆料制备方法进行了展望,指出物理制备方法中的超声波辅助、球磨研磨法,化学制备方法中的干法、半干法以及超声-微波辅助制备中低温水溶淀粉浆料具有很好的发展前景。

Abstract:

With the requirements of energy saving and emission reduction and the need to reduce production costs, the medium and low temperature sizing technology has attracted more and more attention and become a research hotspot. Starch is the principal part of textile sizing material, and its solubility in low and medium temperature water is the key factor to realize medium and low temperature size preparation and warp yarn sizing. The water solubility of starch at low or medium temperature can be endowed by physical or chemical modified methods. The latest research status of preparation methods of water-soluble starch in low and medium temperature is reviewed. The physical and chemical preparation methods of water-soluble starch in medium and low temperature were introduced. The advantages and disadvantages of preparation methods of pregelatinized starch, granular cold water soluble starch, hydroxypropyl starch, carboxymethyl starch, phosphate starch and acetate starch were analyzed, and the effects of key preparation parameters on their properties were discussed. In the end, the preparation method of medium and low temperature soluble starch size is outlooked from the property of water solubility at medium and low temperatures and the view of environmental protection of preparation process. It is pointed out that the ball grinding method and ultrasonic assisted in the physical preparation method. Ultrasonic wave-microwave assisted, the dry process and semi dry process in the chemical preparation method to prepare medium and low temperature water-soluble starch have good development prospects.

Key words: modified starch, textile size agent, water solubility, size mixing at medium and low temperature, warp sizing at medium and low temperature
