精纺毛单纱上浆工艺研究

Research on Single Worsted Wool Yarn Sizing Technology

文章通过测试18tex精纺毛单纱上浆前后纱线的增强率、减伸率、毛羽率、耐磨性等性能,以期得到与进口浆料上浆效果接近的配比方案。结果表明:PVA∶接枝淀粉∶聚丙烯(酰胺)为40∶40∶20,辅以1%抗静电剂,含固量18%,上浆温度75℃,可以达到相近效果。

In order to get the same effect with imported sizing agent,the 18 tex single worsted wool yarn was tested before and after sizing,the performance such as stretching rate,breaking elongation,hairiness index,abrasion resistance times were tested and analyzed.The results showed that the optimal ratio of PVA,grafted starch,and polypropylene（pp）was 40∶40∶20,meanwhile,the antistatic agent was 1%,solid content was 18%,and sizing temperature was 75℃.
