Reactive Dyes Wholesale Application Tips for Cotton Fabric 

Dyeing Process Optimization

• Pre-Treatment of Cotton: Before applying reactive dyes wholesale, cotton fabric should be pre-washed to remove sizing agents, oils, and impurities. This ensures uniform dye absorption—Pengze Technology (Shijiazhuang) Co., Ltd. recommends a mild detergent wash (40–50°C) followed by rinsing and drying.
• Dye Bath Preparation: Mix reactive dyes wholesale with warm water (30–40°C) to ensure full dissolution, then add the recommended amount of salt (50–80 g/L) and alkali (soda ash, 10–20 g/L) to activate dye-fiber bonding. The company’s technical sheets provide precise ratios for different fabric weights and colors.

Post-Dyeing and Printing Care

• Fixation and Washing: After dyeing or printing with reactive dyes wholesale and printing paste, cure the fabric via steaming (100–105°C for 10–15 minutes) to complete dye fixation. Follow with a hot wash (60°C) to remove unfixed dye and paste residue, then a cold rinse to set the color.
