泡沫技术染深色的可行性及其应用

Feasibility study and application of deep color dyeing by foam technology

为了探讨泡沫染色对棉织物染深色的可行性,研究了活性艳红KE-3B在棉织物泡沫染色中的提升力和染色性能;为了推广泡沫染色在纺织加工中的应用,研究了不同类型活性染料在对棉织物的泡沫染色浅、深色工艺中的固色速率和织物K/S值与固色时间的关系。研究结果表明：活性红KE-3B在泡沫染色中具有良好的提升力,经不同质量浓度泡沫染色的织物匀染性好。在4种不同类型的活性染料泡沫染色中,染料的固色率均能达到70%~90%,KN型活性染料固色率最高,固色速率顺序为活性黑KN-B〉活性大红K-2G〉活性艳红KE-3B〉活性艳红X-3B。

In order to study the deep color dyeing by foam technology of cotton fabrics with reactive dye, the build-up property of Reactive Red KE-3B in foam dyeing was investigated. Aiming at promoting the application of foam dyeing in textile processing, fixation rate and relation between K/S value and fixation time in light color dyeing and deep color dyeing during foam dyeing of cotton fabric were studied with different types of reactive dyes. The results indicated that Reactive Red KE-3B had excellent build-up property in foam dying, and dyed fabric had great leveling properties. All dye fixations of foam dyeing with different types of reactive dyes could reach 70% -90%. The highest fixation could be obtained using KN reactive dye and the fixation rate order was Reactive Black KN-B 〉 Reactive Red K-2G 〉 Reactive Red KE-3B 〉 Reactive Red X-3B.
