Fabrics Testing Requirements for Garments

Fabrics Lab Testing: Fabrics need to pass through some testing for their quality, and strength because by cutting and sewing fabrics become garments, fabric lab testing is very much important. The buyer has the requirement to pass the fabrics lab test report before allowing fabrics for garment manufacturing. Here you can find a detailed idea of fabric testing requirements for garments, standard testing method, and buyer-required performance of every testing criterion, this would help you to know about all in-house fabrics testing and its standard testing method.

Where does Fabrics Lab Test need?

  • Fabrics after dying, before delivery to garments
  • Fabrics before cutting, inspection stage of in garments manufacturing

Flammability of Textiles Different textiles’ flammability resistance can be assessed with the tester TF319.
