Reduction-clearing-free liquid nano dispersing colorant

The invention discloses a reduction-clearing-free liquid nano dispersing colorant, and particularly relates to the technical field of dyestuffs. The dispersing colorant comprises the following raw materials in parts by weight: 20-40 parts of pigment, 0.5-1 part of sodium lignin sulfonate, 1-10 parts of polymethylnaphthalene sulfonate, 1-20 parts of fatty alcohol polymer, 1-20 parts of ether oxidederivative and 1-5 parts of polypropylene glycerol ether. The colorant is prepared after being ground and compounded, and can be free of reduction clearing in a dyeing and finishing process, dischargeof sewage is relieved, the dyestuff can be fully dyed on fibers in a using process, the color yield and the color fastness are increased, and the colorant can be increased by 0.5-1 level on the basisof a conventional dyeing process. 本发明公开了种免还原清洗液体纳米分散色浆，具体为染料技术领域。所述的分散色浆包含以下重量成分原料：色料为20-40份、木质素磺酸钠0.5-1份、聚甲基萘磺酸盐1-10份、脂肪醇聚合物1-20份、醚氧化衍生物1-20份、聚丙烯甘油醚1-5份。本色浆经过研磨复配后制成，在染整过程中可以做免还原清洗，减少污水的排放，且此染料在使用过程中能充分的着色在纤维上，提高给色量提高色牢度，能在常规
