摘　　要：针对过氧化物干法制备的变性淀粉纺织浆料黏度不稳定的问题,以淀粉为原料,通过六亚甲基四胺与过硫酸铵协同作用,研制了一种干法制备黏度稳定的淀粉浆料。研究了六亚甲基四胺用量与变性淀粉浆液黏度及黏度热稳定性的关系,对浆膜性能以及对纯棉粗纱粘附力的影响。结果表明:六亚甲基四胺可以提高APS/淀粉浆液的黏度热稳定性,且浆膜性能良好,对纯棉粗纱的粘附力增加。In order to solve the problem of unstable viscosity of modified starch textile size prepared by peroxide dry method, a kind of starch size with stable thermal viscosity was prepared by dry method with starch as raw material through the synergistic effect of hexamethylene tetramine and ammonium persulfate.The relationship between the amount of hexamethylene tetramine and the thermal viscosity stability of modified starch size were studied systematically. What′s more, the effect of the hexamethylene tetramine-ammonium persulfate modified starch on the size film properties and the adhesion of cotton roving were studied. The results showed that hexamethylene tetramine could improve the thermal viscosity stability of ammonium persulfate/starch size, both the size film properties and the adhesion to cotton roving were increased.
