| 摘 要： | 采用浸浆粗纱法研究醋酸酯淀粉浆料的粘附性能，以粗纱条的最大强力和断裂功为量化指标定量研究了淀粉品种、变性程度以及混合浆组分与其粘附性能的对应关系。试验表明，醋酸酯化变性能够改善淀粉对纤维的粘附性能；在变性程度相同时，醋酸酯马铃薯淀粉的粘附性能最好，醋酸酯玉米淀粉次之，醋酸酯木薯淀粉最差；用取代度为0．019的醋酸酯玉米淀粉与PVA-1799混配，在粘附性能方面能够达到玉米原淀粉与PVA-1788混用的效果。

| Abstract: | The adhesion behaviors of acetylated starch sizes to fibre substrates were evaluated in terms of maximum strength and work to break of a slightly sized roving. The relevant relations between the adhesion behaviors and substitution degree of acetylated starch, source of starch, and composition of starch-PVA blend were investigated by using an impregnated roving method. The experiment results demonstrate that the modification of starch enhances the adhesion behaviors to fibres, and the adhesion behaviors decrease with the starch type as following order: potato starch>corn starch>tapioca starch. Comparing with native corn starch/PVA1788, the same effect on adhesion behaviors could be obtained by using acetylated corn strach-PVA1799 blend when the degree of substitution is only as less as 0.019. |
