测试了磷酸-氨基甲酸酯化变性淀粉的透明度、粘度、粘度热稳定性以及对粘胶纱的粘附性能,研究了该淀粉在热敏感型粘胶纱低温上浆中应用的可行性.结果表明:淀粉经复合酯化变性后能改善淀粉糊的透明度,提高淀粉浆液的抗凝胶性能,浆液在60～80℃时仍具有良好的粘度稳定性；能显著提高对粘胶纱的粘附性能,浆液温度的降低对粘附力没有明显影响,能够用于粘胶经纱低温上浆.%The transparency, viscosity, viscosity thermal stability of the phosphate-carbamate starch and the adhesion to viscose fiber were measured. The feasibility of application of starch in sizing heat-sensitive viscose yarns at low temperature was discussed. The results showed that the modification was favorable to improve the transparency and anti-gelling behavior of the starch paste. Phosphate-carbamate starch paste could also keep good viscosity stability at 60～80 ℃. The adhesion of phosphate-carbamate starch for viscose fiber could be significantly improved and the reduction of the temperature of size liquid had little effect on the adhesion. The modified starch could meet the requirements for sizing viscose yarns under lower temperature.
