摘　　要：采用活性染料对真丝和棉进行干法转移印花与筛网印花,以印花废液、印花织物颜色特征值与服用性能对两种印花方法进行对比。研究表明:转移印花废液的COD值均较筛网印花废液低,但其中的染料量较高,印花废液的COD主要由增稠剂引起。筛网印花织物具有较高的匀染性、染料渗透率和色牢度,但是转移印花织物的色泽较深且手感更为柔软。两种印花方法对织物透湿透气性的影响均不大。转移印花织物的强力下降较筛网印花织物稍大,但与原织物相比,下降不显著。Dry-transfer printing and screen printing with reactive dyes are carried out on natural fiber fabrics such as silk and cotton. The two printing methods are compared in terms of printing effluents, color characteristic and wearability of printed fabrics. The results indicate that, the COD of effluent from transfer printing is lower than that of screen printing, but dyes content is higher. COD of the effluent is mainly caused by thickener. Levelness, dye penetration and color fastness of the screen prints are higher, while the transfer prints display a deeper color and softer handle. Both two printing methods have little influence on moisture permeability and air permeability of silk and cotton fabrics. Strength of the transfer prints decline more, but the decline degree can be negligible compared with that of the original fabric.
