II. Scope of Services
Sample polyester/modal knitted fabric, acidic polishing enzyme
Post-dyeing polishing process: apply 1 kg of polishing enzyme, add 500 g of dilute glacial acetic acid, adjust the pH to 4.5, and treat at 50°C for 60 minutes; followed by a softening rinse: use 4 kg of softening oil, 500 g of hydrophilic silicone oil, and 300 g of fluffy silicone oil, then perform rinsing at room temperature for 3–4 minutes, followed by dehydration and drying.
Sample performance: When compared with Demai’s sample at the same dosage, the hair-removal effect is essentially the same. However, the customer has very high requirements for color and luster; today we specifically tested a sensitive shade. After washing, the pH remained at 4.5, and the difference in color and luster compared with Demai is minimal. Moving forward, we still need to further optimize the neutral-pH hair-removal performance. Previous sampling and analysis showed that Demai’s acidic enzyme achieves about 40–50% activity under LFH conditions, whereas our product offers better cost-effectiveness.
III. Feedback
It is currently in stable mass production, with a monthly consumption of 5 tons.
