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 → 1000 percent printing paste

The dyes are first diluted with urea and then dissolved in hot water (below 50°C). The solution is mixed with sodium alginate thickener to form a resistant salt. Just before printing, the cloth is printed by adding sodium bicarbonate to the solution. After printing, the cloth is dried thoroughly. The fabric is then steamed for 30 to 60 seconds on a rapid ager machine. https://bdfabric.com/cotton-fabric-printing-by-reactive-dye/

After steaming, the cloth is thoroughly shaken and washed. The cloth is then boiled for 3 to 5 minutes by adding 2 grams of non-ionic detergent like Lisapol per liter of water. Then it is washed in cold water and dried. Sometimes a dye-fixing agent is added to the water (2-5 g / liter) during the last washing to enhance the fastness qualities of the dye. Here urea helps the dye to mix with the paste and helps the dye to stick to the fabric. Alkali also helps the dye to stabilize the fabric.

This method is useful in the following dyes of Procion ‘M’ class:

Procion Brilliant Yellow ‘M’-6G

Procion Brilliant Red ‘M’-5B

Procion Yellow ‘M’- 6R

Procion Blue ‘M’-5G

Procion Scarlett ‘M’-G

Procion Green ‘M’ 2B

(2) Cotton printing by Procion M class dye-Baking (dry heat) process:

Printing → Dyeing →Dry Heat Washing → Dyeing

Printing recipe:

Procion ‘M’ → 5-50 percent

Urea → 150 – 200 percent

Water → 325 – 405 percent

Sodium alginate →400 percent

Resist salt → 10 percent

Sodium bicarbonate → 15 percent

Total → 1000 percent printing paste

The cloth is printed and dried by printing paste prepared with the help of the mentioned recipe. The fabric is then baked for 3 minutes at 110°C or 1 minute at 200°C in a temperature-controlled electric oven. The cloth is then shaken, washed, and dried.

(3) Cotton printing by Procion M class dye-Pad (alkali) batch process:

Printing → Dyeing →Padding → Batching→ Washing →Dyeing

This method is convenient to use where there is no steaming method or baking method. This printing method is very useful for mercerized cotton.

Printing recipe:

Procion ‘M’ → 40 percent

Urea →100 percent

Water →450 percent

Sodium alginate →400 percent

Resist salt →10 percent.

Total → 1000 percent printing paste

The fabric is dried after printing by the mentioned printing paste. The fabric is then padded with unrefined sodium sulfate (100 ° Tw). Nip-Padding is used for 100% pickup. The cloth is then wrapped in a plastic sheet in a wet and cool place and kept for 30 minutes (batching). The cloth is then washed by shaking it thoroughly in plenty of cold water, boiled in a solution of non-ionic detergent (2 g/liter), washed thoroughly, and dried.

The following dyes of Procion ‘M’ class are generally useful in this method:

Procion Brilliant Yellow ‘M’-6G

Procion Brilliant Yellow ‘M’-4G

Procion Brilliant Orange ‘M’-2R

Procion Red ‘M’-G
