Sizing property of phosphate-carbamate amylose was discussed. Phosphate-carbamate amylose, phosphate amylose and phosphate starch were prepared. Through contrast test,proper substitution of carbamate was identified for phosphate-carbamate amylose. Gelatiniiation temperature, viscosity and viscosity thermal stability were tested and contrasted for pho9phate-carbamate amylose sizing,phosphate amylose and PVA blending sizing,phosphate amylose sizing ,phosphate starch sizing,amylose sizing.com starch sizing. The above sizings were used to size C 19.5 tex yam and T/C 13 tat yam,strength and elongation of the sized yam were tested and contrasted. The result shows that sizing properties of phosphate-carbamate amylose and phosphate amylase & PVA are basically same and better than that of the other sizing obviously, sizing demands of pure cottan yarn and polyester cotton blended yarn can be reached. It is considered that phosphaie-carbamate amylose can be textile size mixture or replace PVA.%探讨磷酸-氨基甲酸酯直链淀粉的浆液性能.制备了磷酸-氨基甲酸酯直链淀粉、磷酸酯直链淀粉、磷酸酯淀粉,并采用对比试验确定了磷酸-氨基甲酸酯直链淀粉适宜于上浆的氨基甲酸酯取代度;测定并比较了磷酸-氨基甲酸酯直链淀粉浆液、磷酸酯直链淀粉和PVA混合浆液、磷酸酯直链淀粉浆液、磷酸酯淀粉浆液、直链淀粉浆液、玉米淀粉浆液的糊化温度、黏度和黏度热稳定性；用以上各种浆液在C 19.5 tex纱和T/C13 tex纱上进行了上浆试验,并进行了强伸性测定和比较.结果表明:磷酸-氧基甲酸酯直链淀粉浆液与磷酸酯直链淀粉和PVA混合浆液的性能基本相当,明显好于其他浆液,可满足纯棉纱和涤棉纱的上浆要求.认为磷酸-氧基甲酸酯直链淀粉浆液有可能成为取代PVA的纺织浆料.
