纤维素纤维的种类对织物热湿舒适性的影响

为更好地了解纤维素纤维的热湿性能,开发舒适性高的织物,文章探究了纤维的种类对织物热湿舒适性的影响,综合评价织物的热湿舒适性;采用控制变量法,选用线密度均为14.8 tex的5种纤维素纤维纱线,即棉纤维、竹原纤维、莫代尔纤维、棉/竹混纺纤维(50/50)、棉/莫代尔混纺纤维(50/50),织成密度接近的纬平针织物,分别测试了5种试样的热阻、湿阻、透气和透湿等指标,选择主成分分析法对各项测试指标分析,建立综合评价公式,得到因子权重。结果表明:纤维种类对织物的热湿舒适性能影响显著,在织物相同结构参数下,莫代尔纤维的热湿舒适性明显优于其他纤维种类。

Effects of cellulose fiber types on the thermal and moisture comfort of fabrics

In order to better understand the heat and humidity properties of cellulose fibers and develop comfortable fabrics,the influence of the type of cellulose fiber on the thermal and wet comfort of the fabric was investigated,and the thermal and wet comfort of the fabric was comprehensively evaluated.The control variable method was used for the experiment.Five different kinds of cellulosic fiberscotton,bamboo,modal,cotton/bamboo(50/50)and cotton/modal(50/50)]with linear density of 14.8 tex were chosen to weave weft plain knitted fabrics with the similar density.The thermal resistance,moisture resistance,air permeability and moisture permeability of the five samples were tested.Finally,principal component analysis was used to analyze the test indexes,establish the comprehensive evaluation formula and gain the weight of factors.The results showed that the fiber type had a significant effect on the thermal and wet comfort of the fabrics.Under the same structural parameters of the fabrics,the thermal and wet comfort of the Modal fiber was significantly better than that of other fiber types.
