PRODUCT INTRODUCTION
Levelling Agent is a high-performance textile auxiliary designed to improve dyeing uniformity and reduce color difference in textile dyeing processes. It helps dyes migrate evenly across fibers, reduces barreling and streaking, and promotes consistent color build-up on yarn, fabric and garment materials.
This product is widely used in yarn dyeing, fabric dyeing, garment dyeing and continuous dyeing processes. It offers good levelling property, low foam, high stability and easy handling. It can be applied in combination with various dye systems and improves the overall quality and reproducibility of dyed textiles.
Our levelling agent is produced under strict process control. It is available in different grades according to dye type, fiber material, dyeing process and application requirement. Each batch is inspected for appearance, pH value, viscosity, active content, foaming property and levelling performance before shipment.
We provide complete export documents including COA, TDS and SDS for quality traceability and customs compliance. Our technical team can recommend the most suitable grade and dosage according to your dye system, fiber material, production process and destination country regulations.

USAGE NOTES
Dosage Control:
The recommended dosage varies by application, typically from 0.3% to 3.0% o.w.f. Start from lower dosage and adjust according to trial result and production condition.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Uneven Dyeing and Color Difference
Unsuitable grade, insufficient dosage or poor circulation causes uneven dyeing.
Solution: Select suitable grade, increase dosage and improve dye bath circulation.
Barreling and Streaking
Poor dye migration, wrong temperature control or unsuitable levelling agent causes defects.
Solution: Use appropriate levelling agent, optimize heating rate and improve circulation.
Foaming Problem
High foam grade, improper dosage or strong agitation causes foam in dye bath.
Solution: Select low foam grade, reduce dosage and control agitation condition.
Poor Compatibility with Dye System
Wrong grade causes precipitation, instability or poor dyeing result.
Solution: Test compatibility before mass production and select matching grade.
Slow Dyeing Speed
Excessive levelling agent may affect dye uptake and slow down dyeing.
Solution: Reduce dosage, optimize addition point and adjust dyeing process.
Low Reproducibility Between Batches
Unstable process, inconsistent pH or temperature causes batch difference.
Solution: Standardize process parameters, control pH and temperature, and use stable grade.
Customs Detention Due to Mismatched Documents
Incorrect HS code or SDS information triggers inspection and detention at destination ports.
Solution: Confirm destination country regulations before order. Standard export data: HS Code 3824.9999, non-hazardous. We supply consistent full-set SDS / COA documents.
High COD Load in Wastewater
High active content or excessive dosage increases wastewater treatment load.
Solution: Optimize dosage, use concentrated grade and cooperate with wastewater treatment.
