摘　　要：探讨氨基甲酸酯淀粉在粘胶经纱低温上浆中应用的可行性。测试了温度对浆液粘度特性以及对粘胶纤维粘附性能的影响，评价了上浆温度与粘胶经纱的浆纱性能之间的内在联系。结果表明：氨基甲酸酯化变性能够使浆液在温度低至60℃时仍具有较好的粘附性能和一定的粘度稳定性；随着氨基甲酸酯淀粉取代度的提高，对粘胶纤维的粘附力增大；在低温上浆条件下，氨基甲酸酯变性有利于改善淀粉对粘胶经纱的上浆性能。当淀粉的取代度大于0．032时，这种淀粉浆料可以在60℃-80℃条件下用于粘胶经纱的上浆。Application of starch carbamate in sizing viscose processing under low temperature was discussed. The influences of temperature on the viscosity characteristics of the starch paste as well as on the adhesion to viscose fibers were measured. The relationship between the properties of sized yarns and sizing temperature was revealed. The result shows that the carbamate modification is capable of making starch paste keep superior adhesion to viscose fibers and a certain extent of viscosity stability when the temperature of the paste decreases to 60℃. The adhesion of starch carbamate to viscose fibers increases with the increase in the degree of substitution of starch carbamate. The modification is favorable to improve the sizing properties of the yarns under lower sizing temperature. The modified starch can be applied to sizing viscose warp yarns under 60℃ - 80℃ if the degree of substitute equals or exceeds 0. 032.
