Used crosslinking agent for pigment printing
Pigment printing is using polymer (adhesive), applied to coloured substances do not dissolve in water (paint), fabric in fabrics on fast formation, transparent, wear-resisting colored film, coating mechanically fixed on the fabric printing method.
Rudely, it is dispatch pigment paste into a paste, then add the adhesive and crosslinking agent, fixing agent), then add some improvement feel softener or catalyst, paint paint paint like a layer of thin film, coating on the cloth. The pigment itself doesn't react to the fabric, but it's glued together by the adhesive, so the adhesive has a bigger impact on the fabric.
The process is simple, high productivity, low cost, low pollution, bright printing lines, easy to spell, widely applied, can be used in various fabrics.
Pigment printing because of extensive use of adhesive, crosslinking agent, the two types of chemical additives in more or less contain toxic, easy to release free formaldehyde, pigment printing is the main source of toxicity. Furthermore, the overall production process of pigment printing is short, and the back trace is not washed, so it is easy to detect harmful substances.
Do home textile fabrics, especially often deal with four cotton printed fabric, all know printed fabric pigment printing, reactive printing, also some fabric imitation activity or semiactive fabric, these are used in the production process from printing to distinguish the raw material or process is different.
Biggest pigment printing market, almost all of the low-end goods is pigment printing, reactive printing and the price the at least one times more expensive than pigment printing price, imitation reactive printing fabric price between the two price, not high not low, bad not bad.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.
Density 1.022
Viscosity (20 ℃) ??mPa·ss290±10
Pour Point ℃-9
Boiling point of310°C
Flash Point°C161.1°C
Reactive dyes are also known as reactive dyes. Reactive printing and pigment printing biggest difference is that in terms of dyeing material, reactive dye molecule contains one or more than one active group, under certain conditions can happen with some groups above the textile fiber chemical reaction, dye reactive combined with fiber molecular form, makes the dye and fiber to form a whole.
Because of reactive dyes can directly and fabric fiber produces chemical reaction, coloring process without the aid of adhesive so whatever on the handle, or better than pigment printing color fastness.
The variety is many, the color is bright, the color fastness is good, the hand feels good, the green formaldehyde content is low, the wash is not easy to fade after washing.
Reactive printing despite a flurry of advantages, but when doing the rotary screen printing, reactive printing line precision is less pigment printing, reactive dye net permeability difference, printing fancy can only use mesh larger low mesh net, control of fine lines and patterns is relatively poor.
Active printing can only do 25 silk (2.5 mm) thick line, the line of coating printing is fine line fine can reach 15 silk (1.5 mm). So, some reactive printing pattern, will adopt active joint printing/coating process, the big piece with reactive printing, large area small design or fine lines with coating printing and dyeing, which guarantee pattern definition also ensures that the fabric handle.
The imitative active printing is after the end, still belong to coating printing essence, choice still is coating in dye. Improve the quality of the paint with finer particle size, which will make the color more uniform. Use high quality adhesive, reduce formaldehyde content, improve fabric feel. According to the modified version of the design, the eye density of the high mesh is used to replace the large area of color. Reducing the texture of the surface of the fabric; Improving the viscosity and dosage of the paste; And so on.
