黑色着色剂在湿法涂层中的应用研究

Study on the Application of Black Colorant in Wet Coating

采用含黑色着色剂的涂层浆对尼龙6织物进行湿法涂层,通过测定着色剂在涂层浆中的稳定性及着色剂对涂层织物的着色性和色牢度等性能,研究了黑色着色剂种类、着色剂复配比例及用量、分散剂种类及用量对湿法涂层性能的影响。试验结果表明:炭黑301和中性染料S-RR在湿法涂层中的应用性能较好,并对其进行复配研究,确定中性染料S-RR和炭黑301的复配比例为3∶1,用量为8g;分散剂为TS100,用量为1.0g。

Wet coating was carried out for Nylon 6 fabrics with coating slurry containing black colorant. The effects of black colorant variety, colorant compound proportion and dosage, the varieties of dispersing agent and dosage on wet coating were studied through measuring the stability of the colorant in coating slurry, its dyeing property and colour fastness for the coated fabric. The results show that carbon black 301 and neutral dye S-RR have good application in wet coating; the pigmenting property is better under the following conditions： the ratio of neutral dyes S-RR and carbon black 301 is 3 ： 1the doses is 8 g and the doses of the dispersing agent TS100 is 1.0 g.
