Custom Define PU Leather Manufacturers & Factories

Conventional dry and wet polyurethane leather relies heavily on organic carrying solvents—primarily Dimethylformamide (DMFa), methyl ethyl ketone (MEK), or toluene. During the coagulation and drying stages, these solvents must be evaporated and washed out, frequently leaving harmful trace residues (often 50–300 ppm) trapped in the cellular structure.

In contrast, JiangXin 100% solvent-free polyurethane utilizes high-solid prepolymers that react and cross-link dynamically directly on the casting line without volatile organic carriers. This eliminates DMFa/toluene entirely (yielding 0 ppm residue), prevents bubble formation, improves physical tensile and peel strength, and produces leather with virtually zero odor.

Our bio-based leather series substitutes fossil-based petroleum polyols with bio-polyols synthesized from non-food agricultural feedstocks, such as industrial castor oil and biological starches. The renewable biological carbon ratio is scientifically measured through radiocarbon dating (Carbon-14 analysis) following ASTM D6866 protocols.

This empirical test distinguishes modern carbon derived from living plants from ancient fossil carbon. We supply official third-party radiocarbon certification reports (BETA Analytic or equivalent laboratories) that support hanging tags and hangtag claims for the USDA Certified Biobased Product program.

Because JiangXin New Material operates under a certified Textile Exchange Scope Certificate for the Recycled Claim Standard (RCS), we maintain unbroken mass-balance accounting throughout our processing facility. When an OEM or brand places an order for RCS-certified synthetic leather, we source traceable recycled post-consumer polyester (rPET) resin and yarn.

Upon production run completion and export packing, our compliance desk submits customs declarations, production records, and shipping invoices to our accredited third-party certification body. The registrar verifies the material balance and issues an official Transaction Certificate (TC) documenting the exact batch volume, buyer identity, and verified percentage of recycled content.

Yes. JiangXin operates an integrated pattern and tooling facility equipped with hundreds of release paper rolls, embossing plates, and custom engraving capabilities. We can match any grain type—from ultra-fine hair cells and linear toothpick designs to heavy pebble, Saffiano, and milled tumble textures.

Thicknesses are custom calibrated between 0.50 mm and 2.20 mm (±0.03 mm tolerance). Substrate backings can be selected from recycled tricot, non-woven microfibers, woven canvas, or bio-cotton, tailored for specific stretch, elongation, or tear parameters.

For custom color matching and physical prototyping, lab swatches (A4 or 1-meter trial yardage) are delivered within 3 to 5 business days. Standard production MOQ is 500 meters per color/grain combination for custom runs, while existing catalog references can be procured in smaller sample quantities.

Bulk production turnaround typically ranges from 10 to 15 days for 20-foot and 40-foot high-cube containers. Because all formulation mixing, casting, surface finishing, and quality inspection occur on-site within our 135,733 m² campus, we control the entire lead-time schedule without outside tolling delays.

We apply a four-tier quality control protocol across every meter produced. Raw polyols and pigment dispersions are batched through automated gravimetric dosing to eliminate human formulation error. During active coating runs, inline laser calipers monitor cross-web thickness profile while automated spectrophotometers log chromatic consistency.

Rolls are cured in climate-controlled hot rooms to eliminate plasticizer blushing or tackiness, followed by roll-to-roll automated optical inspection (AOI) to flag surface blemishes, pinholes, or grain distortions before master rolls are trimmed and packed.
