摘　　要：对不同混纺比例的竹浆/棉混纺纱线的力学性能进行了测试和分析.结果表明,随着混纺纱线中棉含量的增加,其混纺纱线的断裂伸长率呈下降趋势,断裂强力则随着混纺纱线的混纺比的变化出现一个极低值,其曲线呈下凹形;而随着竹浆/棉混纺纱线的混纺比的变化,其弹性恢复率几乎不变.The mechanic properties of bamboo pulp/cotton blending yarns with different blending ratios were tested and analyzed. The results show that with the increase of cotton blending ratio, the elongation at break of the blending yarn decreased, a minimum value in the data of the tensile strength appeared, and its curve is down concave in shape. However, with the variation of the blending ratio, the elastic recovery of the blending yarns basically remained stable.
