摘　　要：测试了磷酸-氨基甲酸酯化变性淀粉的透明度、黏度、黏度热稳定性以及对羊毛纤维的黏附性能,研究了该淀粉在热敏感型毛纱低温上浆中应用的可行性。结果表明:这种变性方式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℃时仍具有良好的黏度稳定性;淀粉经复合酯化变性后,能够显著提高对羊毛纤维的黏附性能,浆液温度的降低对黏附力没有明显影响;磷酸-氨基甲酸酯化变性淀粉浆料能够用于羊毛经纱低温上浆。In this experiment, the transparency, viscosity, viscosity stability of the starch and the adhesion to wool fibers were measured. Application of the starch in sizing heat-sensitive wool yarns processing under low temperature was discussed. The result showed that the modification was favorable to improve the transparency and anti-retrogradated behavior of the starch paste. Phosphate-carbamate starch paste can also keep certain viscosity stability at 60 - 80 ℃. The adhesion of phosphate-carbamate starch for wool fiber can be significantly improved and the reduction of the temperature of size liquid had little effect on the adhesion. The modification can meet the requirements for sizing wool yarns under lower temperature.
