Quality Control

Quality Control at Haining Big Red Horse

At Haining Big Red Horse New Materials Co., Ltd., quality is not just a standard—it is the foundation of our 20+ year reputation. Located in the heart of the "China Warp Knitting Capital," we combine advanced warp knitting technology with pioneering water-based coating R&D to deliver premium Polyester Knitted Fabrics that meet strict international standards.

Our comprehensive Quality Management System covers every stage of production, from raw yarn selection to the final roll of fabric.

Our 4-Stage Quality Assurance System

1. Raw Material Inspection (IQPC)

• Yarn Grading: We source high-tenacity, eco-friendly polyester filaments from industry-leading suppliers. Every batch undergoes strict testing for tensile strength, elongation, and color uniformity before entering our knitting workshop.

• Coating Substance Control: In line with our commitment to sustainability, all water-based coating raw materials are verified to be non-toxic and compliant with international environmental standards (such as REACH and OEKO-TEX).

2. Advanced On-Loom Monitoring (IPQC)

• Precision Warp Knitting: Utilizing state-of-the-art German-engineered warp knitting machinery, our technical team monitors tension, density, and mesh structure in real-time.

• Defect Detection: Our experienced operators conduct continuous visual and mechanical inspections on the loom to eliminate structural flaws, dropped stitches, or oil stains immediately.

3. Water-Based Coating & Finishing Quality Control

• Uniformity Testing: For coated fabrics, we utilize specialized laboratory equipment to measure coating thickness, weight per square meter (GSM), and adhesion strength, ensuring no peeling or uneven texture.

• Functional Validation: According to client specifications, fabrics undergo rigorous testing for water resistance, breathability, flame retardancy, and UV protection.

4. Final Inspection & Rolling (FQC)

• Standard 4-Point System: Every single roll of Polyester Knitted Fabric is inspected on automated inspection tables using the international American 4-Point System for fabric grading.

• Color Fastness Verification: We conduct lab tests for color fastness to washing, rubbing (crocking), and light exposure to guarantee long-lasting vibrant colors.

• Secure Packaging: Finished rolls are wrapped in heavy-duty, moisture-proof double-layer packaging (inner polybag + outer woven bag) to prevent damage during international sea or air transit.

Our Quality Promise: We ensure a 100% traceability system. Every fabric roll is dispatched with a unique barcode/batch number, allowing us to trace its exact production date, machinery, and raw material batch.
