摘　　要：测试评价了6种印花织物的结构性能,包括表面形貌、透气性、浸润性、湿态贴体粘附性以及涂层的耐洗牢度和耐磨性,分析了出汗后印花织物的持续凉感作用机理。结果表明:印花涂层呈现出颗粒状且印花并未完全覆盖纤维,因而印花对织物的透气性几乎没有影响;织物的接触角表明印花涂层具有一定的疏水性,经过印花后织物的芯吸高度增加且湿态贴体粘附性下降,印花涂层具有很好的耐磨性和耐水洗牢度,拍摄的红外热成像表明经过印花后织物的持续凉感效果得到了加强,300 s后印花织物表面的温度降低了1℃~2℃,这是由于出汗后一部分汗液会沿着印花部分的缝隙渗透到织物表面蒸发,产生凉感,而另一部分汗液则会以小水滴的形式存在于印花部分进而给织物带来凉感。The structural performance of six printed fabrics is tested and evaluated including surface morphology,breathability,wettability,wet adhesion of the fabric and wash fastness and abrasion resistance of the coating.The constant cooling effect mechanism of the printed fabric after sweating is also analyzed.The results show that the printed coating appears in a granular form and does not completely cover the fibers,therefore,the breathability of the fabric is hardly affected by the printing.The contact angle of the fabric indicates that the printed coating has a certain hydrophobicity,and the core absorption height of the fabric increases while the wet adhesion decreases after printing.The printed coating exhibits good abrasion resistance and wash fastness.Infrared thermal imaging shows that the constant cooling effect of the fabric is enhanced after printing with a temperature decrease of 1-2℃on the surface of the printed fabric after 300 s.This is because after sweating,a portion of the sweat permeates through the gaps in the printed area and evaporates on the fabric surface,creating a cooling sensation,while another portion of the sweat exists in the form of small droplets on the printed area,providing a cooling effect to the fabric.
