Textile Washing Fastness Test Frequently Asked Questions and Solutions

The Textile Washing Fastness Test is an important test to check whether a textile will lose its colour after washing in water. The following are some common problems and their solutions:

Problem 1: During washing, the fibres come off or the colour falls off badly.

Possible cause: The material itself is not suitable for washing or the washing conditions are not appropriate.

Solution: Select a material suitable for washing during the manufacturing process and ensure that the appropriate temperature and detergent are used in the wash.

Problem 2: Shrinkage or distortion during washing.

Possible causes: Poor material stretch or improper washing conditions.

Solution: Choose a material suitable for washing during manufacture and ensure that the appropriate temperature and detergent are used in the wash. Avoid using excessively hot water or strong rubbing to reduce the risk of shrinkage and distortion.

Problem 3: Poor colour fastness, resulting in fading or staining.

Possible causes: Poor dye fastness or improper washing conditions.

Solution: Use strong dyes and carry out a dye test before washing. Make sure you use the appropriate temperature and detergent in the wash to reduce the risk of fading and staining.

Problem 4: Pilling or feathering after washing.

Possible cause: Inadequate surface smoothness of the material or improper washing conditions.

Solution: Choose a material with a smoother surface during manufacture and ensure that the appropriate temperature and detergent are used in the wash. Avoid aggressive rubbing or over-drying to reduce the risk of pilling and feathering.

Problem 5: Discolouration or oxidation after washing.

Possible cause: The material has been affected by oxidation or chemical reactions.

Solution: Choose materials that are more resistant to oxidation and chemically stable during the manufacturing process, and ensure that the appropriate temperature and detergent are used in the wash. Avoid contact with other materials or chemicals to reduce the risk of discolouration and oxidation.

In conclusion, when testing with the Washing Fastness Tester, you should follow the correct procedures and stay focused to ensure accurate and reliable test results.
