高取代CMC用作活性染料印花糊料

为使CMC用作活性染料的印花糊料,测试了高取代CMC的流变性能、印制性能等,并与传统活性印花糊料海藻酸钠进行比较。研究结果表明高取代CMC成糊率高,具有良好的储存稳定性;其流变性决定了它比海藻酸钠更适合用作亲水性纤维纺织品的精细花纹印花,且其实际印花效果可与海藻酸钠媲美,可以代替海藻酸钠作为活性染料的印花糊料。

High substituted CMC used as the thickening agent for reactive dye printing

In an attempt to use carboxymethyl cellulose (CMC) as the thickening agent for reactive dye printing , the properties of high substituted CMC such as the rheological behavior and printing performance were tested and compared with those of the traditional thickener sodium alginate. The research results demonstrated that high substituted CMC has the advantages of high yield of forming thickening agent and good stock stability. Owing to its rheological behavior, it is more suitable for fine pattern printing of hydrophilic textiles than sodium alginate, and the printed effect was comparable to that of sodium alginate. High substituted carboxyl methyl celluloses are good substitution for sodium alginate for reactive dye printing.
