Indigo Sol Vat Dyes are the complex derivatives of anthraquinone and feature superior fastness properties when these are applied to cellulosic textiles. Made available in powder form, it is preferred to be used in batch dyeing method where these provide fine dispersion characteristics as well as fast rates of reduction.

Features :

• Suitable for high speed continuous dyeing
• Suitable for all pre-pigmentation methods in exhaust dyeing as well as leuco-dyeing techniques
• Bright and holds up better when bleached in comparison to other dyes

Applications :

• Provides for superior coverage over yarn irregularities
• Soluble for viscose, rayon and cotton for providing pale shades
• Also used for over dyeing of shirting materials which come dyed with vat/naphthol dyes
• Used for silk and wool dyeing
• Can be used for mercerized threads as well as also applied on knitted goods

Vat Dyes come under chemical dye class that is applied to cellulosic fiber. As chemically complex dyes, these are insoluble in water and need to be reduced to leuco form in sodium hydrosulfite alkaline solution before applying it to cotton/rayon fiber. Here, air oxidation fixes vat dye strongly on fiber that result in superior light and wash-fastness. With usage possibilities including for dyeing of cotton, wool as well as other fibers, these textile vat dyes also color fast.

Features:

• Optimum purity
• High quality
• Unadulterated

Specification and uses:

• Used on cellulose fibers such as cotton, rayon, jute, coir, linen, etc.
• Color: Dark blue
