摘要
针对春秋户外运动卫衣对面料保暖性和单向导湿性能的需求,依据不对称润湿梯度和间隙梯度变小机理,从结构设计的角度开发具有单向导湿功能的纯羊毛针织面料。对羊毛进行防水和低温等离子体处理,得到亲水性差别化的羊毛;双面组织面料的面纱、连接纱和底纱使用不同亲水性的羊毛与水溶性维纶混纺的纱线,实现面料不对称润湿梯度;通过维纶的水解实现面料自内而外间隙梯度变小,提高面料的单向导湿性。结果表明:防水羊毛的水接触角达到了126°,等离子体处理丝光羊毛的水接触角降至34°,2种羊毛亲水性差异明显;所得单向导湿纯羊毛针织面料蒸发速率达到0.61 g/h,单向传递指数达到635.6%,制备的面料具有优异的速干性能和单向导湿性能。
In order to meet the requirements of thermal insulation and one-way moisture-transfer property of outdoor sportswear in spring and autumn,pure wool knitted fabrics with one-way moisture-transfer function was developed from the perspective of structural design according to the mechanism of the asymmetric wettability gradient and the gap gradient reduction.The hydrophilic differentiation of wool was achieved through water-proof treatment and cold plasma treatment.The asymmetric wettability gradient was achieved through different blended ratio of wool with different hydrophilicity and water-soluble PVA was distributed in the veil,binding and base yarn of double knit,the gap gradient reduction of fabric from inside to outside was achieved by the hydrolysis of PVA,and the one-way moisture-transfer function of fabric was improved.The results show that the water contact angle of water-repellent wool was up to 126°,the mercerized wool treated with cold plasma was down to 34°,the hydrophilic difference between the two kinds of wool is obvious.The evaporation rate of the fabric of pure wool with one-way moisture-transfer is 0.61 g/h,the one-way transfer index can reach 635.6%,the prepared fabric has excellent quick drying and one-way moisture-transfer function.
