柠檬酸氢二铵改善淀粉浆料成膜性的研究

Study on Size Film Property of Modified Starch with Diammonium Hydrogen Citrate

探讨柠檬酸氢二铵在改善变性淀粉浆料浆膜硬脆性上的效果。介绍了柠檬酸氢二铵的基本性能,采用柠檬酸氢二铵作为浆料增塑剂,测试了不同柠檬酸氢二铵含量的变性淀粉浆液的黏附性和成膜性能,并进行了浆纱试验。试验表明,在变性淀粉中加入适量的柠檬酸氢二铵,有助于提高纯棉浆纱和涤棉浆纱的强力、毛羽降低率和耐磨性。认为:柠檬酸氢二铵以适当比例加入到变性淀粉中,能有效改善浆膜性能,提高淀粉浆上浆质量。

Effect of using diammonium hydrogen citrate to improve modified starch size film property was discussed. Basic properties of diammonium hydrogen citrate were introduced. Diammonium hydrogen citrate was selected as size mixture plasticizer,adhesion and size film property of modified starch sizing were tested when adding different contents of diammonium hydrogen citrate,then the sized yarn were tested. The test shows that strength, hairiness and wear resistance of pure cotton yarn or polyester cotton blended yarn can be improved when adding proper diammonium hydrogen citrate in modified starch. It is considered that size film property can be improved, starch sizing quality can be improved when adding proper diammonium hydrogen citrate in modified starch.
