Styles of printing in textile:
The style of printing refers to a close relationship between the chemicals used and the dyestuff or pigment. In other words, the style of printing that can be used to print clothes using various chemicals is called. The printed effect is found on the fabric as it creates a close relationship between the dyestuff/pigment and the chemicals used to create a specific design/pattern on the fabric. https://bdfabric.com/what-are-the-different-thickening-agents/

1. Styles of printing in textile-Direct Style of Printing:
In this method, a printing solution (paste) is made in a container containing dyestuff, adhesive and essential chemicals, and then it is applied directly to the cloth. After printing, fixing is done on the fabric by steaming the dyestuff. Steaming is done for a long time in the absence of pressure and for a short time in the presence of pressure. During this process, the printing is organized by the dyestuff present in the printed part of the cloth. The chemicals used in this process help in the dyeing of a particular place. In this method, a small amount of water is absorbed and the temperature of the steaming helps in the chemical. Direct Styles of Printing typically use Vat, Indigosol, Azoic, Rapidogens, Naphthols and Bases, Pigments, and Reactive dyes.
2. Dyed Style of Printing:
This method is mainly used for mordant color. This method works in two steps. Scoured cotton fabric is first patterned with the help of Mineral Compound, which acts as a mordant. Then the cloth is dried. The fabric is then dyed in a dye bath with mordant color. As a result, the color will appear in the place where the mordant is planted. No color elsewhere. Mordant all the fabrics again. After printing according to the design with acid in it, if the fabric is dyed again with mordant color then no color will be applied on the designed area but all the fabrics will be dyed.
3. Discharge Style of Printing:
This method is called white discharge if the dyed fabric is treated according to the pattern with the help of any other chemical. When any other color is mixed with the chemical and printing is done according to the pattern, the color is removed from that place and a new color effect is created. This is called color discharge. In this method, the dyestuff present in the cloth is usually discharged by Destroy, which is usually done by Oxidation or Reduction. In this process, all the dyes that contain the Azo group are reduced and discharged. Dyestuff that cannot be destroyed by oxidation or reduction is removed by other chemical processes. In this process, all the VAT colors which cannot be easily destroyed are removed by washing by dissolving them with powerful reducing agents like Formosol.
4. Resist Style of Printing:
In this method, the fabric is printed by resisting chemicals before applying dyestuff. It is then dyed in a dye bath. As a result, the rest of the fabric will be colored except the resistive part (print) and the resistive part will be white. This is called White Resist. Again color resist is used to color the design. Resist printing is more complex than discharge printing. Such as Aniline Black cannot be discharged. It is used to resist printing.
5. Raised Style of Printing:
In this method, the printing effect is chemically raised. This type of printing style is used for mineral colors. The fabric is first printed with lead acetate. It is then passed through a solution of potassium dichromate. The result is a yellow color effect of lead chromate. No mordant chemicals are used in this method.
6. Styles of printing in textile-Azoic Style of Printing
In this method, the cloth is dried after printing according to the design by soluble hydroxyl compound or Naphthol. After dipping the cloth in the solution of the base, the color will appear at the place of printing. Brenthol or phenaphthol can also be used.
7. Metal Style of Printing:
The metal style of printing is usually used on expensive fabrics. In this method, the fabric is first printed according to the design by a non-removal type resin. Then fine powders of non-oxidizing metals like gold (Au), silver (Ag), bronze (bronze), aluminum (Al), etc. are spread all over the fabric. As a result, the printing effect will be created in all the places where the resin will be applied. Metal powder and resin can be printed together when the thickening agent is very transparent. For example, Urea-formaldehyde resin is used in printing with Gold and Silver powders.
8. Flock style of printing:
Flocks made of synthetic fibers (colored or white) are cut to a certain length. Although these flocks are not metal, they are attracted by magnets. Then if the magnetic field containing the flocks is brought on the cloth and the flow of electricity is stopped the flakes will spread everywhere on the cloth. After drying the cloth, it will be seen that the resin will stick to the flocks where it was applied earlier and it will be removed from all other places of the cloth. This will create a printing effect on the fabric.
9. Styles of printing in textile-Printing of Lining:
In the case of this style of printing, the printing effect of Fine Line, Dots, and Geometrical design can be generated.
10. Crepe or Crepon Style of Printing:
In this method, the fabric is first labeled dyed and then printed on it with thick sodium hydroxide. However, it is done very carefully. The fabric is then thoroughly washed, treated with dilute sulfuric acid, and dried.
