转杯复合纱的强伸性能

从理论和实验两方面对3种不同结构的棉/氨转杯复合纱的强伸性能进行了分析和比较。实验结果和理论分析均表明,转杯复合纱的强伸性能不仅受其组分拉伸性能的影响,还受到成纱方式的影响;包芯纱具有较高的断裂强力,其次是平行纱,而包缠纱的最低;对于断裂伸长而言,包缠纱最大,其次为包芯纱,平行纱最小。

Tensile strength and elongation of the rotor spun composite yarn

The tensile strength and elongation of three kinds of cotton/polyurethane rotor spun composite yarn with different structures were investigated theoretically and experimentally. Both experimental results and theoretical analysis indicate that the tensile strength and elongation properties of the composite yarns depend not only on the components of the yarn but also on the yarn structure. The tensile strength of the core yarn is the highest, the second is the folded yarn, and the lowest is the wrapped yarn. However, the wrapped yarn has the highest elongation, the folded yarn has the lowest and the core yarn ranks between the two.
