High-Performance Medium-Low Temperature Desizing Enzyme For Textile Pretreatment

Paragraph 1 – What problems does our product solve? Where is it used?

Our Medium & Low Temperature Desizing Enzyme is specifically designed for desizing of cotton, linen, blended fabrics and denim. It efficiently decomposes native starch, modified starch, and certain mixed sizes, thoroughly resolving common issues associated with traditional alkaline or high‑temperature desizing such as size residue, fabric strength loss, and harsh hand feel. Suitable for pad‑batch, jigger, winch, and other conventional desizing equipment in textile mills, it helps you obtain clean and stable semi‑finished goods under mild conditions, providing an excellent foundation for subsequent bleaching, dyeing or enzyme washing.

Paragraph 2 – Differentiated advantages: energy saving, high efficiency, eco‑friendly

Unlike conventional high‑temperature or alkaline desizing processes, our product works efficiently over a broad medium‑low temperature range of 40–60°C and pH 5.5–7.5, significantly reducing steam consumption and CO₂ emissions – saving over 20% in energy costs. Its powerful hydrolysis capability rapidly converts sizes into water‑soluble oligosaccharides and glucose, completely preventing size redeposition and sticky spots on fabric, ensuring a higher desizing rate and cleaner fabric surface. Moreover, the product is non‑toxic, odorless, and fully biodegradable; the desizing wastewater has low pH and an excellent BOD/COD ratio, easily meeting clean production and green textile standards.

Paragraph 3 – Why choose our product over others?

Common desizing enzymes or chemicals often force a trade‑off between efficiency and safety. Harsh alkaline desizing damages fibers and increases wastewater treatment costs; some high‑temperature enzymes are effective but energy‑intensive and narrow in application. Our Medium & Low Temperature Desizing Enzyme achieves a “three‑in‑one” breakthrough – low‑temperature energy saving + complete hydrolysis + fabric protection. It preserves fabric tensile strength and delivers a soft hand feel, avoiding the fiber embrittlement and weight loss caused by alkaline processes. Moreover, it shows excellent stability across different water qualities and size formulations. Choosing us means lower total costs, less environmental compliance pressure, and more consistent desizing quality – giving you a competitive advantage from the very first process step.

Product Parameters:

The enzyme is supplied as a brown flowing liquid with a pH of 6.0–7.0 and an activity of ≥2000 μ/g. It works optimally at pH 5.5–7.5 and temperature 50–55°C, though effective across 40–60°C. Recommended dosage is 2–5 g/L for pad applications or 0.2–0.5% o.w.f. for batch processes. Typical treatment time ranges from 20–40 minutes (batch) to 1–3 hours (pad‑batch stacking), followed by hot wash at 65–75°C. The product is fully water‑soluble, non‑toxic, odorless, and 100% biodegradable. Packaged in 25 kg plastic drums, it must be stored below 50°C in a dry, cool place and is classified as non‑dangerous goods for transport.
