Non Fluorinated Durable Water Repellent Wet Processing Specifications
Non-fluorinated DWR wet processing requires bath pH 4.0-5.5, WPU control, and core cure temperatures of 150-170°C with crosslinkers to pass 10 ppm fluorine limits.
Wet Processing Specifications
Technical Guideline
Documented parameters governing chemical and thermal treatments applied to raw fibres, yarns, and fabrics during bleaching, dyeing, and finishing ensure product consistency across manufacturing sites. Production teams must adhere to wet processing specifications to guarantee that finished textiles meet colorfastness, shrinkage, and hand-feel requirements. These documents act as the primary operational blueprint for dyehouse managers and finishing technicians.
Processing Parameter
Detailed entries specify the required liquor ratios, chemical concentrations, temperature profiles, and processing times for each stage of wet finishing. If these wet processing specifications are not strictly followed, severe shade variation, uneven dye penetration, and structural degradation of the fibres can occur. This precision is especially important when processing blends of natural and synthetic fibres, which require separate, highly specific temperature and chemical conditions to avoid destroying the delicate natural fibres while fully dyeing the synthetics.
Quality Standard
Brand owners and retailers establish these technical limits to maintain high quality across multiple global suppliers. Standardized testing for pilling, tearing strength, and wash durability is carried out on every production lot to ensure it aligns with the wet processing specifications. This continuous evaluation prevents defective or inconsistent garments from reaching retail shelves.
Industrial Compliance
Finishing mills must document and verify their chemical usage to comply with international environmental and safety standards. Verifiable wet processing specifications provide a transparent record of the processing history, showing that no banned substances were used. This detailed documentation is required to achieve eco-certifications and to pass third-party factory audits.
