接枝淀粉浆纱性能的研究
|
摘要
针对涤/棉混纺纱特点,利用不同接枝率的接枝淀粉对涤/棉混纺纱进行上浆测试,探索上浆性能与接枝率内在关系;通过多次实验,确定最优上浆配方,从而在涤棉混纺纱上浆上可取代PVA浆料,从而解决PVA浆料给环境带来的问题。结果表明:与PVA浆纱效果相比,接枝率在18%左右时,浆纱耐磨性和毛羽贴伏、断裂强力等性能较好,浆纱的总体质量较好。
In view of the characteristics of polyester/cotton blended yarn,the sizing test of polyester/cotton blended yarn of grafted starch with different grafting rates was conducted to explore the inner relationship between the sizing performance and the grafting ratio. The optimum sizing formula was determined through multiple experiments,and the PVA slurry was completely replaced in the sizing of polyester/cotton blended yarn to solve the environmental problems brought by PVA slurry. The results showed that,compared with the PVA sizing effect,when the grafting ratio was about 18%,the wear resistance,the sticking force,breaking strength and the overall quality of the sized yarn were better.
