Quality Control Laboratory
Test items and methods may be selected with reference to relevant AATCC, ISO, or GB methods according to the fabric specification and customer program.
Quality Control Across a Coordinated Supply Chain
Fabric consistency depends on more than one production step. Our approach connects knitting control with long-term dyeing and finishing cooperation, supplier review, and production follow-up.
Control Points
Quality Is Managed Through the Process
- 1. Confirm the approved specification and reference sample
- 2. Control knitting construction and production consistency
- 3. Coordinate dyeing and finishing requirements
- 4. Review color, hand feel, appearance, and confirmed test items
- 5. Confirm packing and delivery requirements
Dyeing and Finishing Cooperation
Yiyuan coordinates a production network represented by 200+ dyeing vats and 20+ setting machines. Partner selection and ongoing review focus on process capability, environmental compliance requirements, production stability, and finished-fabric quality.
Supply Risk Management
We use a diversified supplier approach to reduce dependence on a single source. Supplier qualification and capacity performance are reviewed to identify potential risks early and support continuity when production conditions change.
Verification note: Specific test standards, inspection levels, certifications, tolerances, and third-party reports must be listed product by product after customer confirmation.
Operational Quality Resources
From Laboratory Review to Final Fabric Inspection
Quality control is supported by internal testing resources, incoming-material checks, production follow-up, warehouse management, fabric inspection, and pre-shipment reinspection.
3,000 m² Stock Warehouse
Warehouse and distribution resources support selected ready-stock fabrics, stable supply, order preparation, and final reinspection before shipment.
4 Fabric Inspection Machines
Dedicated inspection resources support surface review and final quality checks against the approved appearance and order requirements.
Selected ready-stock fabrics may be available without a production MOQ. Availability, color, quantity, and sampling terms remain subject to current inventory and order confirmation.
Typical Testing Checks
Performance and Colorfastness Review
Testing scope is selected according to the fabric application and customer specification. Typical checks may include tear strength, water colorfastness, rubbing colorfastness, abrasion, and pilling performance.
Tear Strength Testing
Evaluates resistance to tear propagation under an agreed test method.
Water Colorfastness
Reviews shade change and staining after controlled water exposure.
Dry & Wet Rubbing Colorfastness
Checks color transfer under controlled dry and wet rubbing conditions.
Abrasion & Pilling Resistance
Reviews surface durability and pilling tendency through repeated abrasion.
Test method, conditioning, specimen preparation, grading scale, and acceptance criteria are confirmed for each customer program.
