Printing process of nylon fabric by Acid dyes: Introduction: Nylon is a synthetic fiber. Nyla mine Acid P dyes and Procinal dyes are widely used for nylon fabric printing. Procion dyes are also used in some cases. A dye has remarkable washing fastness and lightfastness. But the problem is that deep shade is not available …
Printing process of polyester-cotton blended fabric: Introduction: In this method, two fibers are blended (polyester + cotton) to make cloth. Disperse dye (for polyester) and reactive dye (for cotton) are commonly used for printing such fabrics. Dispersal or duranol dye is commonly used for polyester and Procion dye for cotton. https://bdfabric.com/polyester-fabric-printing-by-disperse-dyes/ Printing process of polyester-cotton …

Polyester fabric printing by disperse dyes: Introduction: Disperses are best for printing on fabrics made of polyester fiber. If the polyester cloth is printed without this dye, all those dyes do not have any washing fastness. When printing polyester fabrics with dispersed dyes such as dispersal and duranol etc., the dye-fixing or development method is …
Application of optical brightening agent on cotton: Optical brightening g agents are easily soluble in water. These can be applied to fabrics just like the dyeing process. That is why they are called colorless dyeing. A special type of finishing process that uses brightening agents to whiten textiles and fabrics is called whitening. The use …

Discharge style printing by vat dye: Introduction: White or color discharge effect can be created on the fabric dyed by VAT dye. This is done by simple reduction or oxidation. In the case of white discharge, it is convenient to use both reduction and oxidation methods. However, in case of color discharge, it is dangerous …
Printing of cotton fabrics with vat dyes: When the cotton cloth is printed with the help of VAT dye, it is a very high-quality printing. Because the washing fastness, light fastness, and rubbing fastness of the fabric printed by this dye are very good. VAT dyes are marketed in different types and categories. However, VAT …
Cotton printing by discharge and resist style: Discharge style printing: In this style, reactive dye discharges the dye from the dyed fabric according to the specific design to create a printing effect on the fabric, which is done by using a reducing agent. Some Procion dyes can be discharged to create a white (white discharge) …
Cotton printing by Procion M class dye: (1) Steaming process: Printing → Dyeing → Steaming → Washing → Dyeing Printing recipe: Procion ‘M’ dye → 10 – 80 percent Urea → 50-75 percent Water → 410 – 520 percent Sodium alginate thickener→400 percent Resist salt L → 10 percent Sodium bicarbonate → 25 percent Total …

British gum or dextrins 7. Carboxymethyl cellulose 8. Methylcellulose 9. Emulsion thickener 1. Starches: Starch is a polymer of high molecular weight …
Wool fabric printing by reactive dye: Introduction: Wool natural protein fiber, which is derived from animals. All impurities in the wool are removed by the scouring and bleaching process before printing. Chlorination is done to prevent shrinkage of wool and to increase the absorption capacity of dyestuff. Wool is very sensitive to alkali, so any …
