Penetrants, levelling agents and pretreatment auxiliaries for textiles.
Textile auxiliaries are process chemicals that make textile pretreatment, dyeing and finishing reliable and repeatable — wetting, penetrating, dispersing, levelling and scouring at each stage. For mill buyers the practical question is not just what textile auxiliaries mean, but which product fits their fibre, machine and bath conditions.
The right auxiliary reduces defects, shortens process time and improves shade consistency. We help buyers compare textile auxiliaries and options against their process chemistry before sampling.
Textile auxiliaries are grouped by the process stage they support. The main types we supply are:
Textile auxiliaries support mills and chemical formulators in Southeast Asia, Europe, North America, India and the Middle East.
Process requirements differ by fabric: polyester dyeing needs precise levelling control to avoid streaks, while denim pretreatment demands strong wetting and penetration in concentrated alkaline baths. Tell us your fibre type, machine and liquor ratio, and we will match the penetrant or levelling agent to that specific process stage before sampling. This stage-by-stage fit is what keeps shade repeatability high and reprocessing low.
The textile auxiliary range covers the pretreatment, dyeing and antistatic chemistries mills ask for most:
Alkali-resistant Penetrant AEP is an anionic isooctanol polyoxyethylene phosphate acid ester (solid content >=98%, pH <3), supplied as a colorless-to-yellowish liquid. It delivers rapid, stable penetration in strongly alkaline baths and scouring liquors where ordinary penetrants break down, and conforms to Q/320621HA070. It is primarily used in textile pretreatment, alkali-bath penetration and scouring.

Isooctyl Phosphate Ester (HA-08) is an anionic phosphate-ester surfactant for textile pretreatment. It provides emulsifying, wetting and dispersing performance in high-temperature alkaline systems and helps penetrate and uniformise scouring and dyeing liquors. Full specification values are confirmed by the client before publication.

Antistatic Agent SN (stearyldimethylbenzylammonium chloride, SDBAC) is a cationic quaternary ammonium antistatic supplied as a reddish-brown viscous liquid (1% pH 6.0-8.0, quaternary ammonium content 48+/-2%). It eliminates static on polymers and textiles, is water- and solvent-soluble, heat-resistant below 180 degC, and gives a long-lasting effect for plastics, rubber and coating processing.

Penetrant JFC is a nonionic, APEO-free C8-C10 fatty alcohol polyoxyethylene ether with ultra-fast penetration, stable physical properties and wide solvent compatibility (1% pH 5.0-7.0, cloud point 40-50 degC, flash point >100 degC). It is used in textile desizing, scouring, bleaching, printing and dyeing for cotton, polyester and blended fabrics.

Penetrant OE-35 is a nonionic isooctanol polyoxyethylene ether penetrant for high-temperature dyeing and finishing (1% pH 5.0-7.0, saponification value 190-210 mgKOH/g, penetration time <=10 s in 1% aqueous). It gives fast penetration with excellent compatibility, low foaming and stable performance across a wide pH range, improving efficiency and quality in textile, leather and paper systems.

A penetrant helps the treatment liquor wet and reach the fibre quickly, which is critical in alkaline scouring; a levelling agent slows and evens dye uptake so colour is uniform. Both reduce process defects but act at different stages.
