What are the criteria for textile pilling tests?

The criteria for textile pilling tests can vary depending on the country and region. The following are some of the commonly used standards for textile pilling:

1. ISO 12945-1: This is one of the pilling test standards issued by the International Organization for Standardization (ISO), entitled "Textiles -- Determination of fabric propensity to surface fuzzing and to pilling -- Part 1: Pilling box method". method". This standard describes the procedure and rating system for pilling tests using the pilling box method.

2. ASTM D4970: This is a pilling test standard published by the American Society for Testing and Materials (ASTM) entitled "Standard Test Method for Pilling Resistance and Other Related Surface Changes of Textile Fabrics. Random Tumble Pilling Tester". This standard specifies the procedure and rating system for pilling tests using a random tumbling pilling tester. 3.

3. BS 5811: This is a standard for pilling tests published by the British Standards Institution (BSI) entitled "Textiles -- Tests for pilling resistance and surface change -- Method of pilling resistance of textile fabrics. Modified Martindale method". The standard describes the procedures and rating system for pilling tests using the Modified Martindale method.

4. GB/T 4802.3: This is a pilling test standard issued by the Chinese National Standard (GB) entitled "Test Method for Pilling Performance of Textiles Part 3: Pilling Box Method". This standard specifies the procedures and rating system for pilling tests using the pilling box method.

These standards provide specific test methods, sample preparation, test conditions and rating systems for pilling tests to ensure consistency and comparability. When performing pilling tests, the applicable standards can be referred to and the test procedures performed in accordance with their provisions in order to obtain accurate and reliable pilling test results.
