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.

1.1 Excellent fastness in each index

It is especially for high fastness request areas and irreplaceable by other types.

Work clothes and Uniforms: work clothes,military uniforms and medical uniforms which need to be specially washed(hypochlorite) or long time sun baked.

Fabrics and household goods:shirt,uniforms,sportswear,towels,linen,textile flock wallpaper,curtain fabric,and other household goods which need to be washed in high-frequency and usual direct sun baked.

Outdoor supplies: sun umbrellas,awnings,tents,waterproof outdoor clothing,and other supplies which demand high climate fastness.

Yarn Dyeing: first seam line and embroidery lines,dyed yarn used to neatening after colored weaving which need chlorine bleaching and rinsing times and times.

1.2 Granule fineness

The original dye made by our company is further purified.After several standard commercialization processing such as high-speed sanding,membrane filtration,high-pressure homogenization etc.it finally comes out by the format of superfine powder with the particle fineness of<1 micron (referring to the fineness when fully suspended in the water).It can be beaten into slurry directly without any sanding.There is very excellent sorption of fiber,high rate of staining and good reproducibility.

1.3 Exterior fineness
