Dyeing auxiliaries play indispensable roles in the polyester dyeing process. From ensuring uniform dispersion and leveling to facilitating dye fixation and enhancing environmental sustainability, these chemicals are vital in achieving high-quality, vibrant, and durable colors. Dyeing auxiliaries for polyester we can provide include:

Catalog	Product Name	pH	Note
DYE-AUX-0122	Disperse Printing Anti-stain Agent	7.5-9.5	Non-ionic. Used for improving the wash fastness of polyester-spandex, polyester, and polyester-printed fabrics through reductive clearing. Applicable for the alkaline reductive cleaning process after disperse dye printing to prevent staining of the unprinted areas. Dosage: 2.0-3.0g/L (~90°C)
DYE-AUX-0123	Fastness Improver for Removing Ammonia	6.0-8.0	Used for improving the wash fastness of polyester blends, polyester, and printed polyester fabrics during reductive clearing. Applied in the post-dyeing reductive cleaning for disperse dyes, compatible with sodium hydrosulfite in the same bath. Protects the elasticity of spandex and prevents discoloration. Dosage: 2-3g/L (~90℃, 20min).
DYE-AUX-0124	Polyester Ammonia Optimizer	3.0-6.0	Used for leveling and correcting dyeing defects on polyester and polyester blends. Demonstrates exceptional migration and diffusion properties, ensuring minimal color shade changes after correction. Dosage: Leveling 0.2-0.5 g/L; Reprocessing 1.0-4.0 g/L.
DYE-AUX-0125	Phosphorus Optimizer	5.0-7.0	Suitable for the leveling and reprocessing of dye defects in polyester and its blended fabrics. Exhibits exceptional dye migration capabilities, minimizing color shade changes and preventing white spots after reprocessing. Dosage: Leveling 0.2-0.5 g/L; Reprocessing 1.0-2.0 g/L.
DYE-AUX-0126	Dye Transfer Optimizer	3.5-5.5	Anionic/Non-ionic Suitable for leveling and dye defect correction of polyester and its blended fabrics. Provides excellent dispersibility and migration with minimal color fading. Dosage: Leveling 0.5-1.0 g/L; Reprocessing 1-4 g/L.
DYE-AUX-0127	Low Temperature Dyeing Agent	2.4-4.5	Suitable for the low-temperature dyeing of polyester and its blends. Possesses an exceptional ability to swell polyester fibers, enhancing dye uptake. Excellent migration and leveling properties, with strong coverage. Low foam, low odor, easily washable, and biodegradable. Dosage: 1.0-3.5% (o.w.f)
DYE-AUX-0128	High Temperature Dyeing Agent	7.5-9.5	Anionic/Non-ionic. Suitable for high-temperature high-pressure dyeing of polyester and its blends. Exhibits excellent initial leveling properties, migration ability, and high-temperature dispersibility with minimal color discharge. Dosage: 0.5-1.5 g/L.
DYE-AUX-0129	Polyester Levelling Agent for Sensitive Color	4.0-6.0	Anionic/Non-ionic. Suitable for the high-temperature and high-pressure dyeing of polyester fabrics. Exhibits excellent initial leveling, migration, and high-temperature dispersion with minimal color stripping. Dosage: 0.5-1.5 g/L.
