Washing-off, pale/medium shades (LR 1:6 and below):

• Rinse for 10 min at 60°C/140°F

• Rinse for 10 min at 60°C/140°F with 1-2 g/l Soaping Agent

• Rinse for 10 min at 60°C/140°F

• Soften as usual or aftertreat (Neutralization at pH 6-7)

Washing-off, dark/deep shade (LR 1:6 and below):

• Rinse for 10 min at 60°C/140°F

• Rinse for 10 min at 60°C/140°F with 1-2 g/l Soaping Agent

• Rinse for 10 min at 60°C/140°F

• Soften as usual or aftertreat (Neutralization at pH 6-7)

Notes on washing off:

No pH adjustment is necessary, pH should 10 to be expected after the first rinse. For thorough washing, the rinsing should be continued until the water remains colored. For efficiency and lower rinsing balls possible.

Stability to chlorine becomes much higher chlorinated water fastness ensures long lasting color quality required by current technical trends. These days, the consumer preference in all fields of textiles use is both for ease and wear and high wash fastness is color stability x and high in washable quality as well. The factor because chlorine is mostly used in tap water to make machine washable, and softening of colors used to be washed more frequently to achieve high color imports.

Dycrofix SEdyes high color intensity results in lower dye and salt requirements, leding to the waem washing System.

A Sustainable Solution for Modern Textiles: Balances economic growth with environmental responsibility. Dycrofix JHP dyes enhance production efficiency while addressing key sustainability concerns, reducing water and energy consumption.

Unmatched Performance for Cotton Dyeing: Sets a new quality standard for deep shades with intense color strength and high wet fastness, delivering superior results from shorter processing times with improved productivity and environmental impact.

Efficient Dyeing with Warm Washing Technology: Ensures rapid and high exhaustion for cotton and cellulosic fibers. Warm Washing System simplifies removal of hydrolyzed dye, reducing water usage by up to 30% and cycle time by 25% while maintaining exceptional wet fastness.

Eco-Friendly and Easy to Implement: Meets rigorous environmental standards, including ZDHC Level 3 and eco-friendly certifications. Compatible with existing recipes and processes, ensuring smooth transition while maintaining vibrancy through multiple washes and supporting sustainability in fashion.

The optional dyeing temperature is 50°C-60°C, but the appropriate dyeing temperature depends on the fabric types and dyeing machines.

To ensure optimum results in reactive printing of woven or knitted fabric all impurities in the fibre, lubricants, auxiliaries and processing chemicals that could react with reactive dyes or adversely affect the printing process must be removed To obtain maximum colour yield brilliancy levelness and wet fastness properties on cotton, it has been mercerized or treated with a caustic soda solution of at least 22 °Be (16.4%) Regenerated cellulosic fibres should be treated in a tensionless state with a caustic soda solution of approx 6-8 °Be (4-5%) Alkaline pretreatment improves further dimensional stability and facilitates washing-off of the prints.

Note: Higher urea amounts recommended for certain fixation methods

First of all the dried prints are impregnated open-width and crease-free with an alkaline fixation liquor and after that fixed as per the available equipment.

A horizontal padder with steel/rubber roller arrangement has effective to apply the alkaline fixation liquor which should allow both face padding and immersion of the fabric, depending on its structure and weight. The padding roller which comes into contact with the printed side of the fabnc should be made of steel (S) and the nip roller should be covered with rubber(R).

Washing-off occurs in two stages: first to remove thickeners, chemicals, unfixed dyes and auxiliaries; second to maximize fastness. Swell dry thickening, remove residual alkali, unfixed dyes and auxiliaries. Best results with spray washing, separated rinse baths, and rapid liquor exchange at 90-95°C. Cold water start is possible.

In two-phase methods, intensively spray to remove thickening, alkali, and unfixed dyes at 40°C. Then wash at 60-70°C and 90-95°C. Use soft water to prevent calcium alginate formation. Complete removal of unfixed and hydrolyzed dyes is essential. Higher temperatures accelerate dye diffusion and removal.
