Advantages
Comprehensively enhance the treatment performance of cotton textiles.
· Does not damage fibers, does not affect fiber strength, and reduces fabric weight loss.
· Improved dyeing performance, with enhanced levelling, increased color yield, and a substantial reduction in the defect rate.
· The fabric feels soft and plush, with a lustrous surface and crisp, well-defined texture.
· If biological finishing is performed after dyeing, the fabric’s color and luster will remain unchanged.
· Offers greater safety and reliability in the refining of specially sensitive fibers, such as natural colored cotton, cotton/wool, cotton/silk, and cotton/linen blends.
Harmless to the environment, operators, and equipment.
· Low energy and water consumption, reduction of TDS, COD, and BOD levels in wastewater, and mitigation of environmental pollution.
· Workplace Safety
· Reduce equipment wear and tear
Shorten processing time and reduce overall costs.
· The enzymatic desizing process can be combined and carried out concurrently with the biopolishing process, or even in the same bath as dyeing, thereby shortening processing time and enhancing production efficiency.
· Reduced fabric weight loss and lower defect rate
· No alkali boiling is required, reducing the consumption of alkali, acid (for neutralization), and water (for rinsing).
· Increased dye uptake, resulting in dye savings
· Alleviate the pressure on wastewater treatment and reduce wastewater treatment costs

Reference Process
a) Knitted fabrics, yarns, and loose fibers
For medium- to dark-colored knitted fabrics, yarns, and loose fibers, bio‑refining can be carried out in batch equipment such as overflow dyeing machines or loose‑fiber/yarn dyeing machines. Under mild conditions—50–60°C and a neutral to slightly alkaline pH—the refining enzyme completes the process in 20–40 minutes. The alkali‑free refining process is gentle, eliminating the need for multiple subsequent rinsing steps, thereby saving water, electricity, and steam, shortening processing time, increasing color yield, and reducing overall costs by more than 50%. Bio‑refining can also be performed in the same bath as dyeing. We recommend that users drain the bath after enzymatic treatment and then refill it with fresh water before proceeding with dyeing.

1. Feed water, heat to 50–60°C
2. Refining enzyme (1.0–3.0 g/L)
3. Drainage

Enzyme refining technical parameters:
• Equipment: Overflow dyeing machine, jet dyeing machine, and open-end yarn/single-yarn dyeing machine
• Refined enzyme: 1.0–3.0 g/L
• pH: 7–9
• Temperature: 50–60°C
• Duration: 30–40 minutes
For light-colored and bright products, conventional bleaching should be carried out after enzymatic scouring, or bleaching can be performed first followed by enzymatic treatment; in such cases, bleaching and dyeing may be conducted in the same bath. Due to the bio-scouring treatment, the dosage of bleaching agent can be reduced compared with the conventional level, but it is recommended that the initial batch be treated at the conventional dosage. Enzymatic scouring improves dyeing performance; for certain difficult-to-dye shades that are prone to uneven dyeing, it can achieve superior leveling and vivid, bright coloration.

2. Refining enzyme (1.0–3.0 g/L)
3. Bleaching Auxiliaries (Conventional Process)

Enzyme refining technical parameters:
• Equipment: overflow dyeing machine, rope dyeing machine, and loose-fiber/yarn dyeing machine
• Refining enzyme: 1.0–3.0 g/L
• pH: 7–9
• Temperature: 50–60°C
• Duration: 20–30 minutes

Traditional scouring employs large quantities of caustic soda and other chemical agents, which not only damage the fibers but also pose environmental hazards. The drawbacks of conventional scouring include the use of chemicals, the need for multiple rinsing steps, the resulting burden on wastewater treatment, and the detrimental effects on the fabric itself. “Biological scouring” is an enzymatic process that is gentler than traditional scouring. This product is a formulated blend of multiple enzyme preparations, with alkaline pectinase as the primary component. Research has shown that pectin acts like a glue, binding impurities such as cotton wax to the cotton fibers; however, these can be degraded by alkaline pectin lyase, making it easier to remove residual wax during subsequent hot-water washing.
