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 dustproof
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.
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
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
Brand world vat dyes have a series of external shape,such as
slurry,powder,granules,etc.in accordance with a wide range of
staining requirements in different dyeing factories during its
marketing operation.In addition,the production and processing show
various colors and appearances which incarnates the dyes quality

4, all kinds of high-quality yarn products: wool with yarn, sewing
head line, embroidery line.
The appearance of the dyes
The company's products after high-speed sanding machine,
nano-membrane filtration, high-pressure uniform machine and other
standard high-quality processing, the formation of ultra-fine
powder, granular fineness in the suspension solution less than 1
When used, you can directly use the pulp, the adsorption of the
fiber is good, after the reduction of high dyeing rate, good
tolerance, high attention.
Restore the dye dyeing mechanism
1, the reduction of dyes
2, leuco dyed
3, leuco oxidation
4, saponification after treatment
