摘　　要：根据纬平织物的热湿传递机制和热湿舒适性能指标,提出利用回归分析的方法研究工艺参数对其热湿舒适性能影响程度的方法。利用测得的纬平织物热湿舒适性能指标运用多元回归分析的方法建立热湿传递规律的数学模型,并利用统一目标法建立纬平针织物热湿舒适性能的综合评价体系。结果表明:纬平织物的热舒适性能主要取决于织物的导热系数和织物厚度;湿舒适性能主要取决于纱线线密度和织物厚度;综合评价体系可以对纬平织物的热湿舒适性能进行有效评价和对比。Based on thermal-moisture transfer mechanism and thermal-moisture comfort indictor of weft knitted plain fabric,a new approach was developed and applied to appraise the relationship between thermal-moisture comfort and process parameters.Using the thermal-moisture comfort data gathered from laboratory,thermal-moisture transfer mathematical models of weft knitted plain fabric were established and optimized with multiple regression analysis.With unified objective method,a thermal-moisture comfort comprehensive evaluation system was established.The results indicated that the thermal comfort mainly depended on thermal conductivity and thickness of the fabric;the moisture comfort mainly depended on thickness of the fabric and linear density of the yarn;with comprehensive evaluation system,the thermal-moisture comfort of weft knitted plain fabric can be evaluated and compared with each other effectively.
