These are monochlorotriazine reactive dyes. Due to single chlorine group they have low reactivity and hence requires severe conditions of fixation with cotton fabric. They can be applied on cotton fabric by both Dyeing and Printing Methods. 1) Exhaust Dyeing   Diagram not to scale     Minutes   Raise temperature to 50°c   Load machine, run liquor and / or fabric.

To this solution add Sodium Alginate and Resist salt and stir well. Add predissolved sodium bicarbonate just prior to printing. Print the fabric and dry. Then steam the dried fabric at 100-102°C for 7-15 minutes Finally wash the fabric and dry. If required can give dye fixing treatment. If high temperature steam is used of temp 110-150°C then steam for 5-3 minutes depending on temperature.   (2) Print - Dry - Bake - Wash - Dry   Recipe Camective 'H & P' Dyes - X Part   Urea - 150 Parts   Sodium Alginate (4%) - 400 Parts   Resist Salt - 10 Parts   Soda ash - 15 Parts   Water - Rest   Total - 1000 Parts   The fabric is printed with above print paste and dried.

It is then padded through sodium. Silicate solution of 100 -102° Tw and kept overnight and then washed and dried. Note : Generally 2 g/l of Sodium Alginate is recommended while padding through alkali to avoid migration. General Washing Method In order to achieve maximum fastness properties a proper wash off is essential for the dyed and printed goods.   Minutes   10 Rinse Cold 10 Rinse Warm 15-30 Soap at the boil. For Very heavy depth shades soaping required twice. 10 Rinse Warm   Rinse Cold until clear solution is obtained. For Medium to heavy shades an after treatment with 1 - 2 g/l dye fixing agent is given at room temperature (40°C at acidic pH of 6- 5.5 to improve fastness properties.)
