Swing Textile Abrasion Tester Meets ASTM D4157 and is suitable for testing the abrasion resistance of fabrics, providing a benchmark for fabric improvement. Principle of the test: install the cloth sample in the shape of a strip on the front and back attachments of the friction head and apply some tension, install the friction fluid on the friction table in the arc shape, put the sample in contact with the friction fluid and apply some tension. load on the sample. The rubbing table oscillates back and forth to rub the sample, and after a certain number of rubs, the change in the breaking strength of the sample is evaluated. ASTM D4157 Textile Abrasion Tester Preparation of the sample before testing: 1. Prepare the specimen: 1. Sampling: take a sample - take a roll of fabric as a sampling unit, in the availableRandomly select a roll from the raw materials, or take a sample agreed upon by buyer and seller. Laboratory sampling - after removing the outer part, the original final sample roll should be at least 1m long and the cut sample part should be at least 50cm from the outside. Try on the swatch - cut 12 swatches, the long side of the swatch is parallel to the warp of the fabric and 6 pieces in the weft direction. Do not cut two samples from the same warp or weft portion of the woven fabric. If there is a pattern on the sample, the sample taken must be able to cut the characteristics of the sample. 2.2 It should be cut in both directions from the long side of the fabric and the banner Sample, the sample should be cut from the long side of the fabric and the diagonal direction of the banner to represent the characteristics of the whole fabric. 2.3 Lock the edge of the scalentillon to avoid mutual entanglement. 2.4 Sample adjustment: The sample must be within the standard adjustment to equilibrate under atmospheric conditions, and the sample weight does not change more than 0.1% every two consecutive hours. 2.5 The prepared sample should be tested for fracture on a tensile strength testing machine to obtain the strength of the sample prior to wear testing. Breaking strength A.
