机织面料吸湿快干梯度结构的构建

采用吸湿快干纤维Coolking及莫代尔、棉和涤纶纤维进行纱线设计,构建了机织面料吸湿快干梯度结构模型,通过疏水性纤维和亲水性纤维的合理配置,变化表里经纱的密度比,利用机织多层结构研制了6种具有导湿快干功能的机织面料。分别测试了这6种面料的毛细高度、保水率、水滴渗透面积和体积、自然干燥率、透气量,采用多项综合值对吸湿快干效果加以评定。结果表明,表里经纱密度比为1∶2的结构在吸湿快干性能上要优于表里经纱比为1∶1的结构,里层纱线由莫代尔/涤纶、Coolking/棉构成的配置吸湿快干性能较好,莫代尔/棉、Coolking/棉的配置其次,莫代尔/涤纶和莫代尔/棉的配置较差。

Construction of moisture absorbent and dry fast woven fabrics

Four kinds of fibers,i.e.,Coolking,modal,cotton and polyester were used in designing yarns,and a model of moisture absorbent and dry fast woven fabric was created.Six kinds of woven fabric with moisture absorbent and dry fast function were developed by rational combination of the hydrophobic and hydrophilic fibers,varying warp density ratio of the outer layer to the inner one (WDROLI),and utilizing multi-layer construction of the woven.The wicking height,water retention value,water drop penetrating area and volume,natural dry rate,air permeable volume of the fabrics were tested respectively and the effect of moisture absorbent and dry fast was evaluated by comprehensive values.The experiment results indicated that the construction of warp yarn with WDROLI of 1∶2 is advantageous over that with WDROLI of 1∶1,and the inner layer of yarn consists of modal/polyester and Coolking/cotton is the best with respect to moisture absorbent and dry fast property,modal/cotton and Coolking/cotton occupies the second place,and modal/polyester and modal/cotton falls in the last position.
