Pigment printing crosslinking agent
Pigment printing paste is composed of paint, adhesives, thickener and other additives such as pigment printing crosslinking agent, catalyst, emulsifier, hand feeling improver.
According to incomplete statistics, about half the world production of printed fabric is pigment printing process, especially in the United States due to produce large amounts of polyester-cotton blended fabric, pigment printing proportion is as high as 80%, while Western Europe accounted for 60% ~ 65%, about 50% in the Middle East Africa, Japan is about 25%, probably in China at the levels of 20% ~ 25%.Pigment printing crosslinking agent has played a large role in it, adding paint printing crosslinking agent coating is more durable.
(1) compared with other dye printing, pigment printing process is simple and convenient paste modulation, if it is only the pigment printing steaming or baking can be ready to send workshop, short technological process, improve the labor productivity, reduce the waste water discharge, the environmental pollution is small.
Chromatography (2) it is complete, the fastness to washing, light resistance, resistance to chlorine bleaching have good color fastness, bright color and print the outline is clear, no selectivity of the fibers, pigment printing can be applied to all kinds of fabrics, especially in blended fabric printing more best choice, the uniform color, won't produce sparkled.
(3) it can be printed with other dyes, can also be used as a coloring of resist printing dye, wide adaptability, easy color matching, dyeing rate because of the great problems and race color, so color with good reproducibility.
It can be used for special printing.If white pigment printing, gold, silver powder printing, fluorescent printing, luminous printing, printing products have the three-dimensional sense, added the flower color variety.
After the product brush wash and rubbing fastness is not good, printing is bad, especially the large area printed fabrics feel bad.
Because the adhesive quality is not stable, sometimes the premature conjunctiva in the printing process, resulting in the inlaying of the spillway and the adhesive blade.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:

Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
The monomers of the preparation of adhesive are mostly toxic. If the monomer in the binder is not divisible, it can affect human health.Pigment printing color brilliance as a structure of dyes, such as coating dye red, bright red color is not like ice copper phthalocyanine blue paint color as on the cloth of bright copper phthalocyanine blue dye.
It is easy to get the skin to the skin, and if the paste is left, it will be difficult to reuse.If use emulsifying paste, because the oil is in printing drying time volatilize and easily pollute air.To sum up, with the development of synthetic fiber and its various forms of blended fabric and the development of coating varieties, pigment printing is increasingly showing its superiority.And the improvement of adhesive properties, the appearance of synthetic paste, the application of hand feeling improver, so that the pigment printing will have a broader development prospect.
Coating is a uniform dispersion system made from organic or inorganic pigments and a certain proportion of glycerin, plain and O, emulsifier and water
The paste solid content is in commonly 14% ~ 14%, most of fineness in 0. 5 ~ 2 microns, if the particle is too small, can make the coating of brilliance is reduced, and the excess inorganic pigment and metal powder grinding will lose its luster, the particle is too large, colour and lustre is dim, tinctorial yield decline, scrub poor abrasion fastness, fine grinding reaches a certain degree of coating has condensed tendency during storage, so generally need to add protective colloid in coating such as emulsifiers or cyclohexanone, etc.
The pigment used for coating should have high stability in light, heat and climate. It should be resistant to acid, alkali, oxidizer and commonly used chemicals, so as to have better sublimation fastness and smoke fastness.Coating should have certain relative density and dispersibility, relative density is too large or too small or dispersed bad, in the color slurry easy to cause coating to float or sink;Want to have taller give colour and cover ability, use a small amount of paint to be able to print a thicker color, and the pattern that print on the deep color does not have mixed color effect with ground color.
The production of calico with paint, rather than dye, was so widespread that it began to treat it as an independent form of printing.Pigment printing is the direct printing of paint, which is usually called dry - process printing to distinguish it from wet printing (or dye printing).
