Fabrics Testing Requirements for Garments

Fabrics Testing Requirements for Garments

Fabrics Lab Testing: Fabrics need to pass through some testing for its quality, strength because by cut and sewing fabrics become garments, fabrics lab testing is very much important. Buyer has the requirement to pass the fabrics lab test report before allowing fabrics for garments manufacturing. Here you can find detail idea of fabrics 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.

Fabrics Testing Requirements for Garments

Where does Fabrics Lab Test need?

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

List of Lab Testing Need to be Done of Fabrics

  1. Dimensional stability/Shrinkage to Laundering/washing
  2. Skew Test
  3. Distortion Test
  4. Dimensional stability to Dry Cleaning
  5. Appearance Rating
  6. Colorfastness to Laundering
  7. Colorfastness to Crocking
  8. Colorfastness to Perspiration
  9. Colorfastness to Water
  10. Colorfastness to Light
  11. Tensile strength
  12. Seam slippage
  13. Seam strength
  14. Tear strength
  15. Bursting strength
  16. Pilling resistance
  17. Fiber content
  18. Fabric weight (g/m2)
  19. Formaldehyde content
  20. Lead content (scrapable surfaces only; children only)
  21. Azoic Dyes
