作者： 王妮 孙润军 College of Textiles Dongkua University Shanghai 200051 College of Textiles Dongkua University Shanghai 200051any properties of polyester filaments such as heat shrinkage tenacity elongation at break and etc. are greatly influenced by drawing so post-drawing is important in downstream processing. As more and more profile fibers and multi-variance fibers used in textile industry the properties of above two kinds of differential polyester filaments after drawing in different heat conditions were studied. Finally following conclusions were obtained: Firstly the tenacity and elongation at break decreases with the rise of Tp. Secondly the tenacity rises but the elongation at break decreases with the increase of Tb. Then when the Tb is low both the shrinkage in boiling water and hi hot air decreases with the rise of Tp while when the Tb is high both the shrinkage rises with the rise of Tp. The last both the shrinkage decreases with the rise of Tb.
Many properties of polyester filaments such as heat shrinkage, tenacity, elongation at break and etc. are greatly influenced by drawing, so post-drawing is important in downstream processing. As more and more profile ... 详细信息
