Textile Processing Enzymes for Faster, Cleaner Finishing
For mills, dye houses and garment laundries in India: match the enzyme to each wet-processing step, starting with desizing, then request a quote with the product, quantity and destination.
Mills, dye houses and garment laundries in India's cotton, denim and blended-fabric clusters are asked to cut water, chemicals and rework while holding shade and hand. Enzymes pay off where one harsh chemical step can be replaced by a targeted one: starch size removal, lower-alkali scouring, surface polishing, stone-free denim washing and peroxide cleanup after bleaching.
This range covers those steps with cellulase, laccase, alpha-amylase, pectinase and catalase systems, supplied to mills and to the textile-chemical distributors who serve them. Activity runs from 10,000 to 50,000 U/g; most steps work at 40°C–60°C, and desizing grades up to 95°C. Products come as brown powder or dark liquid in 25 kg drums, 200 L barrels or custom packs, with a 25 kg minimum order and a 12-month shelf life sealed in a cool, dry place.
Desizing is where many lines start, because size left on the cloth turns into dyeing faults later; the desizing notes below set out the routes and the acceptance check. For a wholesale quote, send the product or process step, the quantity and the destination country.
Biopolishing for smoother cotton and blends
Surface fibrillation causes fuzz, pilling, and dull fabric appearance. Acid cellulase-based textile enzymes remove loose microfibrils from cotton and blends, enhancing smoothness and color without harsh abrasion. Processing at pH 4.5–5.5 and 45°C–55°C, dosage is tuned to fabric weight and finish goals for a cleaner hand feel and stable visual quality.
Denim washing without stones
Stone washing risks excessive wear, dust, and inconsistency. Acid or neutral cellulases in denim washing create controlled fading and softness while eliminating pumice stones. For the jeans-specific process, see this page on cellulase for jeans. Running at pH 5.0–7.0 and 40°C–60°C, these enzymes yield vintage looks with less damage and cleaner, safer operations.
Desizing: choose the route by size type, then check the desizing rate
Size put on the warp for weaving sits between the fibres and blocks dyes and chemicals, so it has to come off before scouring and dyeing. Enzyme desizing is the route for starch size: alpha-amylase breaks the starch chains into dextrins and maltose that rinse out easily, under mild conditions and without attacking the fibre. The bath is kept near neutral, with sodium or calcium chloride often added as an activator. Padded fabric is batched at 40–50°C for 1–2 hours; bacterial amylase tolerates more heat, so it can also be steamed for 3–5 minutes on a continuous range.
Bio-scouring and bleach cleanup for lower effluent load
Pectinase-based bio-scouring removes waxes and impurities from cotton at reduced temperatures, replacing caustic chemicals. Catalase rapidly decomposes residual peroxide post-bleach, cutting rinse cycles. Together, these steps lower chemical use and effluent burden while speeding pretreatment.

Frequently Asked Questions
What should buyers check when comparing textile enzymes manufacturers?
Evaluate activity specifications, application fit, batch-to-batch consistency, and technical support. Ensure the enzyme works within your process pH, temperature, and liquor ratio, and is available in a stable format for your operations. Review shelf life, packaging, and industrial documentation. A strong supplier should also guide on correct dosage and compatibility for desizing, biopolishing, denim washing, scouring, or bleach cleanup.
How do textile processing enzymes improve wet processing efficiency?
By targeting specific substrates, textile enzymes replace or reduce harsh chemicals in key steps. Alpha-amylase in desizing breaks down starch rapidly at high temperature, pectinase in scouring removes impurities at lower alkalinity, cellulase in finishing smooths fibers, and catalase post-bleach removes residual peroxide within minutes. This accelerates processing, reduces water and energy consumption, improves fabric hand and appearance, and lowers effluent load.
Which desizing route fits which fabric?
Cotton can be desized with enzyme, alkali, oxidant or acid, so the size recipe decides. Viscose is usually sized with starch and is desized with amylase in the same way as cotton. Lyocell carries starch or modified-starch size and takes an enzyme desize or a one-bath alkali-oxygen treatment. Polyester-cotton is usually sized with a PVA, starch and CMC mix, which points to hot alkali or oxidant desizing rather than enzyme alone. Wovens with spandex are normally enzyme-desized in open width and relaxed, to spare the elastane. Knitted fabric is not sized, so a knit line has no desizing step.
How do we know desizing is complete before dyeing?
Mills normally ask for a desizing rate of 80% or more, or residual size of 1% or less of fabric weight; what remains comes off in scouring. Size left on the cloth shows up after dyeing as shade differences, uneven dyeing, lower colour fastness, spots and uneven lustre. Alkali desizing works on every size type but removes less, and it needs thorough washing with frequently changed wash liquor. Acid desizing can damage the fibre and is used only together with alkali or enzyme desizing; oxidants such as hydrogen peroxide are especially suited to PVA size. To quote the right desizing grade, tell us the size type, the fabric and whether you run pad-batch or a continuous steamer.
What dosage range is typical for textile enzyme applications?
Dosage depends on fabric type, enzyme activity, process target and equipment, so it is set by trial on your own line; higher-activity grades need less product for the same effect. On this range, desizing grades run up to 95°C, while biopolishing and denim washing run at 40–60°C.
Are these textile enzymes suitable for India-based manufacturing lines?
Yes. Grades are chosen for the fabric and the process step, and a trial on your own water, batch size and machines sets the final recipe. Packs from 25 kg drums to 200 L barrels suit regular procurement, the minimum order is 25 kg, and we ship to 80+ countries; freight and lead time are quoted per order.
Can one supplier cover multiple textile processing steps?
Yes. Many mills choose a single supplier for desizing, biopolishing, denim washing, scouring, and peroxide cleanup to streamline procurement and quality control. A capable manufacturer offers enzymes across all these steps with aligned specifications and application support, simplifying trials and standardising performance across the wet-processing workflow.
