Advantages
1. Highly concentrated liquid formulation with flexible preparation and safe operation;
2. Effectively hydrolyzes and removes starch sizing agents, with outstanding biodegradability;
3. Reduce the use of chemicals to lower the COD and BOD in wastewater discharge;
4. Improve fabric wettability and enhance fabric hand feel;
5. Suitable for desizing treatment of cellulose fiber fabrics, including 100% cotton, cotton/blended synthetic fibers, and artificial cotton.
6. It is miscible with most nonionic surfactants, but compatibility must be verified first.

Note: The use of a nonionic wetting agent during enzyme scouring can ensure thorough penetration of the enzyme solution, resulting in improved desizing performance.
Jig dyeing machine: Set the desired temperature and run 2–4 passes. Pad–stack/pad–roll: Ensure thorough liquor uptake and a stacking time of 2–24 hours. The stacking time should be determined based on the enzyme dosage, fabric type, type and amount of sizing agent, and stacking temperature.
Calendering and steaming: Ensure thorough liquid pickup. The calendering and steaming time should be adjusted based on the difficulty of desizing and the dosage of WT-A.

	Process Flow	Recommended dosage	Mainly used for fabrics
Piling Method	Scorching (two passes, front and back) → Enzyme padding (50–70°C, padding ratio 80–100%, stack at room temperature for 4–10 hours, pH adjusted to 6–8) → Hot-water washing (60–95°C, 3–6 rinses) → Cold-water rinsing	Desizing enzyme WT-B 0.5–1 g/L Nonionic penetrant 1–3 g/L	Cotton woven, rayon woven, and blended fabrics
Steam cooking	Burning off the hair (two passes, front and back) → Enzyme padding (50–70°C, padding ratio 80–100%, pH adjusted to 6–8) → Steam treatment (100–110°C, 10–20 minutes) → Hot-water washing (60–95°C, 3–6 rinses) → Cold-water final rinse	Desizing enzyme WT-B 0.15–0.4 g/L Nonionic penetrant 1–3 g/L	Cotton woven fabric
Impregnation method	Bath ratio: 1:10; treat at 60–80°C for 10–30 minutes → rinse thoroughly with hot water. Jig dyeing machine: 60–80°C × 6 reciprocating passes → rinsed with hot water	Desizing enzyme WT-B 0.2–0.4 g/L Nonionic penetrant 0.5–1 g/L	Viscose woven and blended fabrics

Wide-Temperature Desizing Enzyme WT-B

During the weaving process, yarns are typically sized to enhance weaving efficiency; among sizing agents, starch-based sizes are the preferred choice for cotton, cellulose fibers, and blended fabrics.
To ensure effective fabric pretreatment and the smooth execution of subsequent dyeing and other finishing processes, it is essential to thoroughly and uniformly remove sizing agents from the fabric. The removal of sizing agents enhances the fabric’s wettability, thereby achieving satisfactory dyeing and printing results. Inadequate removal of sizing agents can lead to uneven dyeing, inter-batch color variations, and defects in printing.
High-concentration desizing enzyme WT-B is a broad-temperature amylase that effectively removes starch-based sizing agents. It acts exclusively on starch sizes and therefore does not adversely affect the fibers.
