摘　　要：为进一步提升再循环转杯纱的成纱性能,采用由旧纺织品制备的再循环棉与原棉进行混纺,制成再循环棉/原棉转杯纺混纺纱。分析纱线线密度、转杯转速、捻系数、分梳速度等工艺参数对制备的转杯纱质量指标(如断裂强度、疵点、条干CV值、毛羽等)之间的相关性。针对再循环纱线耐磨性差的缺点,运用因子分析法对断裂强度、断裂伸长率、条干CV值、粗节、细节、毛羽等纱线基本指标参数进行分析,提取力学因子、外观因子和毛羽因子3个主因子,分析了各主因子与纱线耐磨性能的关系,探究纱线基本性能对其耐磨性能的影响规律。结果表明:纱线耐磨性随外观因子、力学因子和毛羽因子的增大整体呈现降低趋势;并在此基础上,利用加权综合法对外观因子、力学因子和毛羽因子综合计算不同纱线的综合得分,结果表明耐磨性能随综合得分的增大而降低,二者之间接近线性关系。Objective Fibers recycled from waste textiles is known for their reduced length,hence it is hard to spin as yarn again.However,it can be spun by rotor spinning which is well known for its low raw material requirements.The method to spun recycled yarns gives highlight of extremely useful of waste textiles.However,the yarn showed some disadvantages,such as low strength and poor abrasion resistance.Taking recycled rotor spun yarn as the research object,the correlation between different rotor spinning processes parameters,basic yarn performance indicators,and abrasion resistance of recycled rotor yarns is investigated.Method Compared to raw cotton,the quality of recycled cotton fibers such as the fiber length,strength,and so on deteriorated to varying degrees.Recycled cotton is difficult to form yarn.Rotor spinning is adopted to mix raw cotton(length of 28 mm)and recycled cotton(length of 9.5 mm)at a ratio of 65/35 to form recycled rotor spinning yarn.Spinning was carried out under different process parameters including linear density,rotor speed,twist coefficient,and carding speed.Performance of yarns such as strength,evenness,and hairiness were evaluated.Correlation analysis is adopted to study the influence of yarn process parameters on yarn performance.Factor analysis is adopted to comprehensively study the influence of yarn performance indicators on abrasion resistance.Results The performance of recycled rotor spun yarn with different parameters is compared.It is found that the breaking strength(correlation coefficients of 0.697^(*))and elongation(correlation coefficients of 0.769^(*))are significantly correlated with the twist coefficient.With the increaseing twist coefficient,the strength and elongation of the recycled rotor spun yarn also increases.The carding speed has the greatest correlation with CV(correlation coefficient of 0.540)value.As the carding speed increases,CV value first decreases and then increases.A significant correlation exists between hairiness and linear density(correlation coefficient of
