The flammability test of fabrics is an important method to evaluate the flammability of fabrics, and it is of great significance in the development and production of textiles. Commonly used fabric flammability test methods include the following steps:
Prepare test samples:
Cut the fabric sample into 2-3 samples of equal length and width along the weft and warp directions, and the samples should be randomly sampled from the same cloth.
Conduct flammability test:
Place the test sample on the combustion equipment at a specific location, and the combustion equipment should comply with international or national standards, such as ISO 6941, ASTM D6413, etc.
Observe the flammability test results:
Evaluate the flammability of the test sample by observing the burning performance and duration of the sample during the combustion test, as well as the residue and smoke after burning.
Processing test results:
According to the test results, the samples can be classified and evaluated, such as A1 (non-combustible cloth), A2 (slightly flammable cloth), B1 (semi-combustible cloth), B2 (light flammable cloth), B3 (moderately flammable cloth) cloth) and C (heavy combustible cloth), etc.
It should be noted that when testing the flammability of fabrics, the test standards and operating procedures must be strictly followed to ensure that the test results are accurate and reliable. At the same time, it is also necessary to protect the safety of experimenters and avoid unsafe conditions during the combustion of test equipment and samples.
