Brand World vat dyes produced by jiangsu world chemical co.ltd.belong to the type of anthraquinone and anthrancene ketons,which is applied for the dyeing of cotton,linen,rayon and blended fabric matericals.It appears to the environmental dustpro of particles with very good water diffusion,uniformity of dispersion and anti-cohesion of suspension.It is particularly applicable to high-speed continuous dyeing and continuous padding with automatic mixing owning to its fast speed of reduction.

vat dyes do not dissolve in water,while when reduced to be leuco salt by reducing agent under alkline conditions, they can dissolve in water and get feature of immediacy with cellulose fibers,which is the way to achieve the purpose of dyeing,then stable shade and good color fastness would come out via oxidation and soaping.

Vat dyes dyeing process

Vat dyes do not dissolve in water, while when reduced to be leuco salt by reducing agent under alkaline conditions, they can dissolve in water and get feature of immediacy with cellulose fibers, which is the way to achieve the purpose of dyeing. Then stable shade and good color fastness would come out via oxidation and soaping.

 

Reduction of dyes

Insoluble reducing dye will change into soluble leuco.

Different levels of the best staining methods are brought out according to the reduction dyes’ reduction potential and level of its immediacy to fibers.

 

 Leuco Oxidizing

The leuco absorbed by fiber is oxygenated and changed into the former insoluble vat dyes, then it colors.

Scour them in 2-3 baths with soft ware before oxygenation, avoiding to be oxygenated with alkali.

Hydrogen peroxide is most suitable for suspension padding, while after oxygenation, it should be in soap boiling immediately without washing.

The sodium perborate is mild in very widely use. It can be bathed with the next procedure (referring to soap boiling).
