Range and Application Fit

We configure the right chemistry around the fiber type, contaminant profile and machine layout. All pretreatment products in this category are liquid formulations that can be diluted, pumped and integrated into batch or continuous wet-processing lines.

Critical Specifications and Formulation Approach

For a pretreatment chemical, the measurable values matter most during scale-up: pH in a 1% solution, ionic character, solubility, foaming behavior and emulsifying performance. Our scouring and degreasing products are mostly anionic/nonionic blends with pH in the 6.0–8.0 range, which helps protect spandex and nylon from alkali damage.

Solubility: scouring products mix with water in any ratio; reducing cleaning agent YH-RCE is easily soluble in water.
Foam profile: low-foam formulas are supplied where overflow, airflow or open-width continuous machines require stable bath behavior.
Storage: sealed products remain stable for six months in a dry, cool and well-ventilated warehouse.
Packaging: standard supply is 50 kg or 125 kg plastic drums.

Machine Compatibility and Process Throughput

The same fabric can behave very differently in a jig, a rope overflow machine, an airflow machine or an open-width continuous range. We match product selection to the actual machine circulation, liquor ratio and temperature limits so the chemistry performs without foam control problems or oil redeposition.

YH-1102 is suitable for pure nylon, nylon blends, polyester and polyester/nylon composite fabrics, and works in both batch and continuous lines.
YH-1104 is positioned for nylon-spandex and polyester-spandex stretch fabrics in jig, rope overflow and conventional open-width continuous degreasing.
YH-102A is designed for scouring, desizing and degreasing on cotton, polyester, nylon, spandex and blended fabrics, and can be combined with leveling agents, chelating agents and softeners for one-bath processes.

For one-bath scouring and dyeing programs, we coordinate the pretreatment product with the corresponding Textile Dyeing Auxiliaries range to avoid bath conflicts and preserve dye uptake.

Controls and Automation Integration

Our pretreatment products are designed for modern dosing systems. Because they are liquid and pumpable, they can be fed directly through automated metering stations, dilution tanks and pH adjustment loops without special handling equipment.

For continuous ranges, we confirm wetting time, foam stability and emulsifying power under the proposed dilution ratio. For batch machines, we provide dosage ranges and rinsing guidance that keep cycles short and reproducible.

Quality, Acceptance and Compliance

We develop and manufacture these products with in-house R&D covering raw material evaluation, formulation design, process optimization and quality control. The product file for each item includes physical and chemical properties, application method, features and packaging.

OEKO-TEX certification information is maintained for the relevant product portfolio.
We are actively working toward ZDHC membership and prioritize low-foam, deeply rinsing formulations that reduce water and energy use.
During acceptance, common checks include appearance, pH in a 1% aqueous solution, solubility, emulsifying behavior and performance against the agreed process target.

After pretreatment, downstream results can be further improved with the Textile Finishing Auxiliaries range for hand feel, pile raising and protective functions.

Custom Development and Project Support

We co-develop new specialty items with customers and adjust formulations through trials. This is useful when a mill runs unusual blends, high-silicone knits, heavy oil contamination or restricted chemical lists.

For niche functional requirements, we can also coordinate with our Specialized Textile Auxiliaries Chemical range, which covers antimicrobial, anti-mildew, UV-shielding and high-stability dye-fixing products for demanding textile programs.

Customer FAQs

Can your pretreatment auxiliaries be used in one-bath scouring and dyeing processes?

Yes. Textile Degreaser YH-102A is formulated for combined scouring and dyeing and is compatible with leveling agents, chelating agents and softeners. We recommend a lab trial to confirm the dosage and temperature profile for your blend.

What is the difference between YH-1102 and YH-1104?

YH-1102 is a broad-spectrum scouring and degreasing agent for non-stretch synthetic fabrics such as pure nylon, nylon blends, polyester and polyester/nylon composites. YH-1104 is designed specifically for nylon-spandex and polyester-spandex stretch fabrics.

Do you customize formulations for a specific machine or restricted chemical list?

We work with customers to co-develop specialty products and adjust formulations to fit machine constraints, contamination levels and compliance requirements. Please share your process conditions and target performance values.

What packaging and storage conditions apply?

Standard packaging is 50 kg or 125 kg plastic drums. Store drums sealed in a dry, cool and well-ventilated warehouse; the shelf life is six months under those conditions.

Do you provide technical support during first production trials?

Yes. Our technical service covers product selection, dosage recommendations, trial monitoring and adjustment of the pretreatment formula to meet your absorbency, whiteness and downstream dyeing targets.
