影响羊毛横机织物热传递性能因素的研究

Study on the heat transfer performance of knitting wool fabric

为了研究羊毛纤维横机织物热传递性能,分别对羊毛横机织物的未充满系数、厚度、单位面积干燥质量以及织物密度与导热系数的关系进行了研究与分析。结果表明随着羊毛织物未充满系数、织物密度的升高,导热系数λ逐渐减小,即织物热传递性能下降,而随羊毛织物单位面积干燥质量和织物厚度的增加,导热系数λ呈增加趋势,织物的热传递性能上升。

In order to study the heat transfer performance of knitting wool fibers fabrics, the relationship between eoefficient of thermal conductivity and other factors such as opening percentage, thickness, dry weight per unit area and fabric density are analyzed. The results show that the coefficient of thermal conductivity decreases, namely fabric heat transfer performance de- clines with the increase of wool fabric opening percentage and fabric density. With the increase of fabric thickness and wool fab- ric weight per unit area, the coefficient λ of thermal conductivity increases, and the heat transfer performance increases too.
