Briefly. The production of calico from paints rather than dyes has become so widespread that it has begun to be used as a stand-alone method of printing. Paint printing is the direct printing with paint, a process often called dry printing, to distinguish it from wet printing (or dye printing).

This paragraph is reviewed. Definition. One of the process methods of fabric printing. Unlike dyes, paints have no directness to fibers.

It cannot be combined with fiber, it is just an insoluble colored powder, mostly organic synthesis, but also inorganic. It is "colored" on the fiber by means of a synthetic resin that produces a strong film, which is fixed on the surface of the fiber, so that it can be printed on fabrics of various fibers.

Characteristic. 1. The printed fabric has bright and bright colors and good light stability. It can be endowed with a plump, dry and soft feel of the fabric, especially the excellent friction fastness, the correct use of dry and wet grinding fastness can reach more than 4 grade (reference only), excellent washing fastness, and good air permeability of the fabric.

2. The printing paste has excellent chemical and physical stability, and is not affected by the composition of the printing paste. The net permeability is good, and the printing machine is easy to clean.

How to distinguish between paint printing and dye printing.

By comparing the difference in hardness between printed and unprinted parts of the same fabric, it is possible to distinguish between paint printing and dye printing. The painted area is slightly stiffer to the hand than the unprinted area, perhaps a little thicker. If the fabric is printed with dyes, there is no significant difference in hardness between the printed and unprinted parts.

Transfer the print. First of all, the computer is used to separate the color of the pattern Then, the pattern is sewn into a first-class quality transfer printing roller (gravure) by a high-precision Swiss MDC electric engraving machine Using electronic engraving rollers and inks, the pattern is printed on special paper, which is the thermal transfer printing paper After a certain amount of time, temperature and pressure control, the pattern is printed on the cloth Finally, the printed cloth is sewn into a variety of exquisite home textile products, clothing, travel supplies, etc., and enters thousands of households to decorate and beautify people's lives!

It's liquid wallpaper, and it's also a kind of paint that paints the wall and is patterned, the same as wallpaper.

According to the different solvent systems used in the color paste, the color paste is divided into water-based color paste, oil-based color paste, and water and oil general color paste; Water-based colorants are water-based systems, while oil-based colorants are oil-based or solvent-based systems, and the application systems and environments of the two are different. In addition, they also have their own focus on application fields, environmental protection characteristics, packaging requirements, technical performance, etc. As far as the current market is concerned, water-based colorants are more environmentally friendly than oil-based colorants, and oil-based colorants have a wider range of applications than water-based colorants.

However, from the perspective of the entire coating development environment, the development space of water-based colorant is better than that of oil-based colorant, because water-based colorant is more environmentally friendly, and there is room for development in application development and technical performance. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again! <>

The main components of paint printing paste are: paint color paste, adhesive, cross-linking agent, thickener (or synthetic thickener) and other additives.

1) Paint color paste.

It is made by mixing pigments, dispersants, wetting agents and water, etc., and then grinding them by mechanical grinding. Pigments include inorganic pigments, organic pigments and fluorescent resin materials, which are the coloring parts of paint printing.

2) Adhesives. It is a polymer film that covers the surface of the fabric with pigments so that the color is fixed on the surface of the fabric, which plays the role of paint color fixing.

3) Crosslinker.

The function in the printing paste is to play a cross-linking role, so that the linear adhesive molecules form a network structure, make the adhesive film elastic, and improve the dyeing fastness. The dosage of cross-linking agent should be controlled appropriately, and the increase in the dosage is conducive to the improvement of the dyeing fastness, and the excessive amount is not conducive to the feel of the fabric.

4) Thickeners. It acts as a carrier in paint printing, so that the coating adhesive and other additives are evenly dispersed and transferred to the knitted fabric. There are two types of thickeners used: emulsified paste and synthetic thickeners.

The main problem in the use of synthetic thickeners is that they are not resistant to electrolytes, which will make the printing paste thinner, reduce the viscosity, and infiltrate the printed pattern, which will affect the printing effect. In the production of full-paint printing, synthetic thickeners can be used. Anti-printing and dispersion coating printing paste contains electrolytes, which should be noted.

1 The chemical classification of pigments (paint pastes) pigments is mainly as follows:

1) Inorganic pigments.

2) Organic pigments.

3) Fluorescent resin coatings.

4) Metal powder.

5) Pearlescent pigments.

6) Cover coating 2 adhesive adhesive is mostly composed of polymers composed of two or more monomers, and can also be composed of several polymers.

3 Thickeners 4 Other additives.

When using the all-water-based or semi-emulsified coating printing process, it must be considered whether it can reach the level of printing the physical object of using emulsified paste as thickened paste, for this reason, it should be noted when choosing other additives: (1) The surface of the printed fabric should have bright color, clear pattern outline, and uniform block surface.

2) The electrolyte content should be low to reduce the amount of synthetic thickening paste, which is conducive to the improvement of hand feel.

3) Make the printed fabric have good rubbing fastness and washing fastness.

Q: A: In order to improve the performance of the printing paste, facilitate the smooth printing process, and also improve the printing quality, the following additives can also be added to the coating printing paste.

Hygroscopic agents. Its main function is to keep the surface of the printing paste moist to prevent crusting, especially in the high temperature season, which can improve the stability of the color paste. Hygroscopic agents include ethylene glycol, glycerin, urea, etc., and urea is generally used as a hygroscopic additive, because urea also has the function of capturing free formaldehyde.

Softener. It can make the surface of the pattern printed on the fabric smooth, soft to the touch, and can also be appropriately improved in the fastness to friction, especially for printed fabrics with high hand feel requirements, special softeners for coating printing need to be added, generally high-concentration hydrophilic softeners containing silicones (such as Alcoprint 1739, Luprimol Sig). If the hybrid emulsifier Luprintol MCL is added to the paint printing paste, in addition to the softening and defoaming effect, it can also improve the rheological properties of the printing paste and make the pattern contour clearer.

Rheology improver. When the synthetic thickening paste is used as the thickener of the coating printing paste, the printing of synthetic fiber fabrics or pure cotton fabrics with high pattern fineness often produces defects such as poor clarity of the pattern contour, and the addition of Carbopol Printrite PM to the printing paste can improve the fluidity of the color paste and avoid the phenomenon of pattern seepage. Crosslinkers.

The fastness of the adhesive can be improved by adding a crosslinker to the paint printing paste. Among the self-crosslinking adhesives, it is advisable to use modified melamine helizarin fixagent LT, which can improve the printing fastness of the adhesive on pure cotton, synthetic fibers and blended fabrics, and the formaldehyde content is low, but hexamethylol methyl etherified melamine is also used as a crosslinking agent. In non-self-crosslinking adhesives, cross-linking agents EH and Acratix FH are often added to the printing paste, and the adhesive film after baking with such cross-linking agents is easy to yellow.

Dispersants. The main function is to improve the stability of printing paste, and anionic surfactants are generally used.
