三组分花式线的强伸性能预测与分析

The Forecast and Analysis of the Strength and Elongation for Three-Component Fancy Yarn

为了研究三组分花式线的力学性能,对其强力的构成进行理论预测和试验分析,从花式线组成出发,分析了三组分花式线的结构和影响因素;然后通过拉伸应力-应变曲线,对常见三组分花式线进行了强伸性能的测定;最后,对3种三组分花式线的强力进行了理论预测和试验分析。结子线的强伸性能有较大差别;圈圈线的强伸性能主要由芯纱决定;氨纶包缠纱由氨纶提供弹性,由包缠在氨纶外侧的非弹性纱决定纱线的强力。

To investigate the mechanical performance for forecast and analysis of strength constitutes, the structures and influencing factors of three-component fancy yarn are studied in this paper and then the strength and elongation properties are dealt with based on the tress-strain curve. Finally, the strength of three-component fancy yarn is forecasted and analyzed theoretically. The strength and elongation properties of the loop yarn are mainly decided by the core yarn. The elasticity of the wrapped spandex yarn is provided by the spandex whilst the non-elastic yarn wrapped outside the yarn spandex decides the tenacity.
