This article explains the main functions and practical usage of Huntsman auxiliaries across pretreatment, dyeing, and finishing processes.

1. Huntsman Auxiliaries for Fabric Pretreatment

Pretreatment is the foundation of successful dyeing and finishing. Huntsman provides auxiliaries for desizing, scouring, bleaching, and neutralization.

Main Functions

Efficiently remove size, oil, wax, pectin, and impurities

Improve absorbency and whiteness of fabrics

Reduce fiber damage and ensure uniform dye uptake

Ensure low foaming, high temperature resistance, and environmental safety

Typical Products & Usage

Scouring & Wetting Agents

Improve wetting speed and emulsify impurities.

Dosage: 0.5–2 g/L, applied in batch or continuous scour bleach lines.

Hydrogen Peroxide Stabilizers

Stabilize bleaching, prevent over-oxidation and holes.

Used in caustic or alkaline peroxide bleaching systems.

Sequestering / Chelating Agents

Capture heavy metal ions (Fe, Cu) to protect dyes and fibers.

Widely used in hard water areas.

Key Processing Tips

Follow recommended pH and temperature for low-foam running

Ensure uniform liquor circulation for even pretreatment

2. Huntsman Auxiliaries for Dyeing Process

Huntsman dyeing auxiliaries are specially designed for reactive, disperse, acid, and cationic dyes, matching its famous dye ranges such as Avitera®, Eriofast®, Foron®, and Lanasol®.

Main Functions

Improve levelness and migration to avoid streaks and spots

Promote dye absorption and fixation

Reduce salt/alkali consumption in eco-friendly dyeing

Enhance color fastness and reproducibility

Suppress foam and ensure smooth machine operation

Typical Products & Usage

Leveling Agents

Used for polyester, cotton, and wool to ensure uniform color.

Dosage: 0.5–1.5% on weight of fabric (o.w.f.).

Dispersing Agents

Prevent agglomeration of disperse dyes during high-temperature dyeing.

Fixing Agents for Reactive Dyes

Improve wet fastness, washing fastness, and perspiration fastness.

Anti-foaming & Defoaming Agents

Ensure stable operation in jet dyeing machines.

Usage Guidelines

Add auxiliaries before dyes to ensure pre-wetting and leveling

Control heating rate for sensitive shades

Use low-salt auxiliaries to meet green production targets

3. Huntsman Auxiliaries for Textile Finishing

Finishing auxiliaries determine the final hand feel, appearance, functionality, and durability of fabrics.

Main Functions

Provide soft, smooth, or crisp hand feel

Improve wrinkle resistance, hydrophilicity, or water repellency

Enhance anti-pilling, anti-static, and durability

Ensure low formaldehyde or formaldehyde-free for apparel textiles

Typical Products & Usage

Softening Agents

Give natural, silky, or bouncy hand feel.

Applied by padding or exhaust method.

Hydrophilic Auxiliaries

Keep moisture absorption while maintaining softness — ideal for sportswear and underwear.

Cross-linking / Easy-care Agents

For cotton easy-care, wrinkle-resistant, and durable press finishing.

Fastness Improving Auxiliaries

Boost washing, rubbing, and light fastness for deep shades.

Application Tips

Strictly control baking temperature and time

Ensure compatibility between different finishing auxiliaries

Test small samples before mass production

4. Advantages of Using Huntsman Auxiliaries
