双亲性淀粉浆料的研究进展

Research progress in amphiphilic starch sizing agents

为提高淀粉的上浆性能,分析了对淀粉进行双亲性变性处理的意义,总结了双亲性淀粉浆料,包括阴阳离子型双亲性淀粉浆料、亲疏水型双亲性淀粉浆料,在纺织经纱上浆中应用的研究现状,论述了双亲性变性对淀粉浆料黏附性和浆膜力学性能的作用效果,并对今后双亲性淀粉浆料的研究方向进行了预测。认为亲疏水型接枝改性淀粉浆料品种及适宜于具体经纱品种的双亲性淀粉浆料品种,以及可降低均聚物产生、可控接枝支链长度的淀粉接枝改性方法将是今后双亲性淀粉浆料的重要研究方向。

To improve the sizing property of starch sizing agents,this paper analyzed the significance of amphiphilic modification of starch,and reviewed the research progress in the amphiphilic starch sizing agents that contain anionized-cationized starch sizing agent and hydrophilic-lipophilic modified starch.The effects of amphiphilic modification on adhesion and film properties of starch were discussed,and the research direction of the amphiphilic starch sizing agents was predicted.It is pointed out that study on new hydrophilic-lipophilic grafted starch sizing agents and amphiphilic starch that is suitable for sizing specific warps,and investigation of new graft copolymerization methods for preparing new amphiphilic grafted starch sizing agents,should be the important research directions in the future.
