涤纶印花用免水洗液体分散染料的应用

Application Research of Non-washing Liquid Disperse Dyes for Polyester Printing

对比分析涤纶印花用免水洗液体分散染料与常规市售粉状染料在印花后颜色深度相同条件下面料耐摩擦色牢度、水泡残液、耐水洗色牢度(沾色)和印花水洗色变方面的差异,探讨达到相同印花黏度,粉状分散染料和液体分散染料所需增稠剂用量。结果表明,印花液体分散染料表现出优异的性能,采用印花液体染料的涤纶面料具有耐摩擦色牢度高、水泡残液清、耐水洗色牢度(沾色)高、水洗前后几乎无色差、印制浅色均匀且无色点、相同黏度所需增稠剂用量少的优势.

The difference between washing-free liquid disperse dyes and conventional commercially available powdered dyes under the same color depth after printing is compared and analyzed in terms of dry and wet rubbing fastness,blister residual liquid,color fastness(stained)to washing and color change of printing.The study compared the amount of thickener needed to achieve the same printing viscosity between powder dyes and liquid dyes.The results shows that liquid disperse dyes show excellent performance.Polyester fabrics using liquid dyes have high rubbing fastness,clear blisters,high staining fastness to washing,and almost no color difference after light washing,printed light color uniform,no stained points,with the advantage of less thickener with the same viscosity.
