Migration textile dyes

Because of the strong temperature dependence of exhaustion and the poor migration properties, dye absorption must be as level as possible from the start. Correspondingly, attention should be paid to uniform packaging, package density, liquor flow or movement of textile material, and controlled machine conditions. 

Specialty chemicals producers must find an answer to the exodus of customers to emerging markets, which not only threatens to break up established supplier-customer relationships, but has the potential to destabilize entire segments. This is particularly true for formulation-based segments such as admixture chemicals for the concrete industry, which depend on close interaction with customers. What happened to textile dyes in Europe is just one particularly striking example the migration of the European textile industry to Asia and subsequent emergence...

Is used in the textile industry as an antistat and lubricant for wool and synthetic fiber processing, and as a co-emulsifier and antistat in synthetic fiber spin finishes. It is also an anti-precipitant, leveling, and migrating agent in various dyeing procedures, and an antistat in carpet shampoos. 

If they are ingested, dyes and particularly those that have an azo group can be metabolized by the intestinal microflora or by the liver enzymes. So, their effects can occur in organs responsible for metabolism or elimination, like the liver and urinary tract. Skin metabolism may also be responsible for the transformation of dyes, for example, those from colored textiles that can leach from the fabric and migrate to the skin. For example Disperse Orange 3 is degraded to p-phenylenediamine (PPD) and nitro-aniline in the skin (Figure 1). Direct Blue 14 (Cl 23850), after azo reduction, converts to the aromatic amine o-toluidine and other amines when incubated with cultures of Staphylococcus aureus.
