A common dye aid used in the printing and dyeing process.

original title: common printing and dyeing process used dye additivesin the printing and dyeing process, when using dyes, inside not only dye raw powder, that is, in addition to dye, but also add some aids, in turn to improve dyeing efficiency and effectiveness. The following Huaboxing technology for you to briefly introduce the dye additives usually added in the dye category: , dispersants:should be the dye commercialization of the most used additive varieties, the general varieties are: 1, lignin sulfonate sodium: sodium lignin sulfonate is an anion-type active surfacter. It has a strong dispersion capacity and is suitable for dispersing solids in water media.2, dispersant NNO: chemical name is methylene disulfonate sodium, methylene disulfonate sodium. Dispersant NNO is mainly used to disperse dyes, reduced dyes, active dyes, acid dyes and leather dyes as dispersants, abrasive, ever soluble, dispersive excellent.3, dispersant MF: methyl sulfonate formaldehyde shrink, mainly used for dispersing dyes, reducing dye grinding processing agents and dispersants, dispersion performance is better than the dispersant NNO.4, dispersant CNF: alpha-methylmethyl sulfonate formaldehyde shrink, the main chemical group is divided into pyridine sulfonate formaldehyde shrink, high temperature resistance is the best of the three formaldehyde shrinks of sulfonate.5, dispersant SS: alkyl benzene formaldehyde shrink, the main chemical group is divided into methtophenol, sulfonate and formaldehyde shrink, mainly used for the grinding of dispersed dyes., filler:in order to adjust the dye to meet the standard force, add neutral fillers: 1, sodium sulfate, that is, Yuanming powder, basically all kinds of dyes will be added;2, dextrin, mainly used in cation dyes.three, dust agent:to prevent dye dust flying, usually add dust agent, generally include: 1, mineral oil emulsifier 2, alkyl steaplastsadditives are usually added in powder synds, if it is a liquid dye, but also add thickener (viscosity regulator), anti-mold agent, chelating dispersant, non-volatile solvent, polyglycol compounds.
