How to distinguish color fastness Thank you, the national standard for color fastness testing

Legal analysis: The mandatory national standard GB18401-2010 "National Basic Safety Technical Specifications for Textile Products" stipulates that the color fastness index of qualified products must be greater than or equal to grade 3.

Legal basis: Article 2 of the Standardization Law of the People's Republic of China The standards (including standard samples) mentioned in this law refer to the technical requirements that need to be unified in the fields of agriculture, industry, service industry and social undertakings.

Mandatory standards must be enforced. The State encourages the adoption of recommended standards.

The European standard and the American standard for fabric color fastness testing are different in the temperature, time, detergent dosage, washing equipment, etc. And the standards in Europe and the Americas are not the same.

Color fastness is also known as color fastness and color fastness. It refers to the resistance of the color of the textile to various actions during processing and use. The fastness grade is graded based on the discoloration of the specimen and the staining of the undyed laminating fabric.

Textile color fastness test is a routine test item in the intrinsic quality test of textiles.

Colour fastness test Note:

Colour fastness to light refers to the degree to which coloured fabrics are discoloured by sunlight. The test method is to compare the degree of fading of the sample after simulated sunlight with the standard color sample, and it is divided into 8 grades, with 8 being the best score and 1 being the worst. Fabrics with poor color fastness to sunlight should not be exposed to the sun for a long time, and should be placed in a ventilated place to dry.
