Denim Wet Processing Chemicals
Denim Wet Processing Chemicals is a product line supplied by Jiangyin Huanan New Material Technology Co Ltd for use in denim garment washing operations including desizing bleaching neutralizing and softening stages. Established in 1984 and operating two production plants with an annual capacity of 60000 tons the company formulates auxiliaries that support enzyme based and conventional wash recipes on cotton and stretch denim fabric. The line covers desizing agents oxidative and reductive bleaching agents anti back staining agents neutralizers and finishing softeners used across stone wash acid wash and distressed wash programs. Formulations are offered in APEO free and low formaldehyde grades to align with OEKO TEX ISO 14001 and ISO 45001 requirements giving denim laundries and garment finishers a documented option for compliance driven production runs supplied to domestic and export customers.
Core Advantages
Stage specific formulation
Separate products for desizing bleaching neutralizing and softening allow each wash stage to be controlled independently rather than relying on one general purpose auxiliary
Enzyme process compatibility
Neutralizers and softeners in the range are formulated to work alongside cellulase enzyme systems without interfering with enzyme activity during stone wash and bio polishing steps
Back staining control
Anti back staining agents reduce indigo redeposition onto the fabric surface during bleach and stone wash cycles supporting cleaner ground shade results
Documented compliance grades
APEO free and low formaldehyde versions are available with supporting documentation for laundries supplying OEKO TEX certified brand programs
Product Range
| Desizing agent | Enzymatic and acid based removal of starch size prior to wash |
| Bleaching agent | Oxidative and reductive grades for stone wash and acid wash shade development |
| Anti back staining agent | Reduces indigo dye redeposition during bleach and enzyme wash stages |
| Neutralizer | Stabilizes fabric pH after bleach or enzyme treatment before softening |
| Finishing softener | Cationic and silicone based options for hand feel adjustment on finished denim |
| Packaging | 25kg 200kg or bulk container on request |
Conventional vs Enzyme Based Processing
Conventional Wash Process
- Relies on pumice stone abrasion combined with oxidative bleach for shade development
- Higher mechanical wear on fabric and washing equipment over repeated cycles
- Bleach dosage is the primary lever for achieving the target ground shade
Enzyme Based Wash Process
- Uses cellulase enzyme activity in combination with reduced stone volume for surface abrasion
- Lower mechanical wear supports fabric strength retention across the wash cycle
- Neutralizer timing controls enzyme deactivation and final shade consistency
Application Scenarios
The chemicals in this line are selected according to the target wash effect and fabric construction across the following denim finishing programs
-
Stone wash denimEnzyme and reduced pumice combination for a worn faded appearance with controlled fabric strength loss
-
Acid wash denimOxidative bleach with anti back staining agent for high contrast marbled shading effects
-
Bio polished denimCellulase treatment paired with neutralizer for a smooth surface finish on stretch denim fabric
-
Soft hand finishingCationic or silicone softener applied at the final rinse stage to set garment hand feel before drying
Neutralizer dosage and treatment time should be confirmed on a trial sample before bulk processing since incomplete neutralization after enzyme or bleach treatment can affect downstream softener performance
Frequently Asked Questions
Can the desizing agent be used on stretch denim containing elastane
The enzymatic desizing agent is suitable for cotton elastane blended denim and dosage should be adjusted based on fabric weight and size add on level to avoid over treatment of the elastane component
How does the anti back staining agent affect ground shade
The anti back staining agent limits redeposition of released indigo dye onto the fabric surface during bleach or stone wash which helps maintain a cleaner ground shade rather than adjusting the shade itself
Are formaldehyde free softener options available
Low formaldehyde and formaldehyde free softener grades are offered within the range to support production for OEKO TEX aligned garment brand programs
What packaging sizes are available for bulk laundry use
Products are supplied in 25kg containers 200kg drums or bulk container format for laundries with larger consumption volumes
