Printing process of nylon fabric by Acid dyes:
Table of Contents
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 with this dye. Acid dyes are also occasionally used for nylon printing. Dispersal and Duranol of Disperse Dye are also rarely used in this fiber. However, washing fastness is not very good. The pigment is also used for light and medium shades. Between the two types of nylon, nylon 6 absorbs water or dye easily but nylon 66 absorbs water slowly. And its washing fastness and light fastness is better than nylon 6. https://bdfabric.com/printing-process-of-polyester-cotton-blended-fabric/
Nylon Fabric Printing by Nyla mine Acid P Dye:
Nylon fiber is not as easy to print as other fibers because it has low moisture retention. The solubility of Nyla mine acid p dye is very good for fastness qualities and the ability to make printing shades.
Printing process of nylon fabric by Acid dyes-Recipe:
Nyla mine acid P dyes → 30 – 60 percent
Glide ‘BN’ → 50 percent
Hot water → 330 to 360 percent
Dispersal VP → 10 percent
Nafka Crystal Gum → 450 percent
Thai urea → 50 percent
Perminal KB → 20 percent
Ammonium sulfate → 30 percent
Total → 1000 percent printing paste
The dye is dissolved in glide ‘BN’ and added to hot water with dispersal VP. This solution is then added to Thai urea and Perminal KB dissolved gum and finally, ammonium sulfate is added.
The fabric is printed and dried according to the design with the mentioned printing paste. The fabric is then steamed for 30 minutes at atmospheric pressure. The fabric is washed after steaming. The cloth is then washed in a solution of 1%/1000% sodium carbonate mixture for 5 to 10 minutes. The cloth is then washed in water mixed with 2%/1000% lisapol and 1%/1000% sodium carbonate at 60°C for 5 to 10 minutes. The cloth is then washed in water containing 1%/1000% acetic acid. It is then washed in cold water and dried.
