摘　　要：为了改善玉米淀粉浆膜脆、硬的缺点,对玉米淀粉氧化,在碱性条件下与溴代十二烷进行醚化反应,制备了具有优异韧性浆膜的十二烷基化淀粉浆料。采用红外光谱对制备的十二烷基化淀粉浆料进行表征,并对其浆液、浆膜各项性能指标进行测试;分别用含有十二烷基化淀粉和磷酸酯淀粉的浆料配方对14.6 tex纯棉纱线上浆并测试浆纱性能。结果表明:此制备方法能够将烷基链引入到淀粉结构上,得到十二烷基化淀粉浆料;十二烷基化淀粉浆料成膜后浆膜柔软,对棉纤维黏附力好;使用十二烷基化淀粉浆料浆纱,纱线毛羽降低率及纱线增强率均优于磷酸酯淀粉浆料的浆纱。In order to improve the shortcomings of brittle and hard corn starch slurry.the corn starch was oxidized and etherified with bromododecane under alkaline conditions to prepare dodecylated starch slurry with excellent toughness.Infrared spectroscopy was used to characterize the prepared dodecylated starch slurry.and the performance indexes of slurry and slurry film were tested.The sizing properties of 14.6 tex cotton yarn were sipped with a slurry formulation containing dodecylated starch and phosphate starch.respectively.The results show that the alkyl chain was successfully introduced into the starch structure to obtain a dodecylated starch slurry.The dodecylated starch slurry forms a film,the film is soft,and the adhesion to cotton fiber is good;By using dodecylated starch sizing.the hairiness reduction rate and yarn reinforcement rate of yarn were better than those of phosphate starch sizing.
