天然纤维织物热转移印花的颜色特征

The Colour Characteristic of Heat Transfer Printing on Natural Fibre Fabrics

棉、苎麻、蚕丝织物经预处理变性后，热转移印花，多数染料的转移率接近涤纶织物，但表面色深值都普遍低于涤纶织物，而且得色鲜艳度和色相，都发生不同程度的变化；其中真丝双绉转移印花后表面色深值、色相和鲜艳度较棉和苎麻更接近于涤纶织物。

The transfering rate of most disperse dyes on cotton,ramie and silk which have been modified through pretreatment,is approximate to that on polyester fabric. But the colour intensity of natural fibre fabric is lower in general,and the brilliancy and hue on them change to different extent. Compared to cotton and ramie,the resulting colour characteristic on silk is more similar to that on polyester fabric.
