Beyond Stretch: The Key Quality Indicators We Check in Every Knit Fabric

For any serious bulk purchase, assessing a knit fabric goes far beyond just testing its stretch. Consistent, measurable quality is what protects your brand reputation and ensures customer satisfaction. At Zhejiang Kingtex, as a supplier to major global retailers, our quality control is built on verifying these key performance indicators in every batch.

The Critical Quality Indicators We Measure

When you place a large order, you need guarantees. Here are the non-negotiable checks we perform:

• Dimensional Stability & Shrinkage: Will the garment maintain its size after washing? We conduct standardized wash tests to measure and control shrinkage rates, ensuring the finished product meets your spec.
• Colorfastness: Will the color bleed or fade? We test for colorfastness to washing, rubbing (dry/wet), and perspiration to ensure colors remain vibrant and consistent through wear and care.
• Fabric Weight (GSM) Consistency: Is every roll uniform? We verify that the Grams per Square Meter (GSM) is consistent across the entire production run, which is crucial for cost control, yield calculation, and product feel.
• Pilling Resistance: Will the fabric form unsightly pills? We use Martindale or random tumbler tests to objectively evaluate the fabric's surface durability for a premium look over time.
• Tensile Strength & Durability: Can it withstand stress? We test the fabric's resistance to tearing and bursting to ensure it meets the durability requirements of its end use.
• Composition & Eco-Compliance: Is it what it claims to be? Through thorough documentation and supported by our GRS, OCS, and OEKO-TEX certifications, we verify fiber content and ensure materials are free from harmful substances.
