A method for quantitatively detecting the abrasion resistance of fabrics using a Martindale abrasion tester

Summary: Evaluation of fabric abrasion resistance The method is divided into subjective method and objective method. The subjective method has a big error in qualitative assessment. Although the fabric abrasion index in the objective quantitative evaluation is accurate, it does not take into account the damage caused by the damaged fibers and yarns on the surface of the fabric in the wear rate Hairiness and hairballs have some influence on the result. This item uses the G235 Martindale Abrasion Tester supplied by Standard Group (Hong Kong) Co., Ltd. be removed by scorching. The method of wear resistance of the fabric, and briefly described the experimental process, introduced the characteristics of the use of equipment, which can serve as a reference for scientific research units, test institutions and related enterprises toevaluate product performance.

1, meaning

The abrasion resistance of the fabric is closely related to the abrasion resistance of the clothing when it is actually is being carried. At present, there are mainly two methods to test the wear resistance of clothing fabrics: actual wearing experiment and instrument method experiment. The wearing experiment determines the limit of whether the underwear can still be used according to the actual usage requirements; generally speaking, the wear holes of a certain size on the hips or knees of the pants or the fraying of the pants are up touses a certain length as the elimination limit, which is more consistent with the actual wear. However, the carrying test costs a lot of manpower and material resources, and the test takes a long time, so it is difficult to adopt. Instrument methods include plane grinding, curved grinding, edge grinding, dynamic grinding, rotary grinding, etc., which are relatively mature and widely used. There are subjective methods and objective methods for the evaluation of the wear resistance of fabrics. The subjective method has a big error in the qualitative assessment. Although the wear rate index of the fabric is accurate in the objective quantitative evaluation, it does not take into account that the surface of the fabric is damaged by fibers and threads. The hairs and balls produced by the thread have some influence on the result.

This item uses the scorching method to express the fabricAfter the hairing and pilling are removed from the surface, the actual wear rate is used to evaluate the wear resistance of fabrics, to achieve the goal of quantitatively evaluating the wear resistance of clothing fabrics, and to investigate the laws of fabric wear resistance.

4、Standards and methods

With Standard Group (Hong Kong) Co. , Ltd. Martindale Abrasion Testing Machine, combined with GB/T21196.3 test to test sample abrasion resistance

5、Survey method

Cut 3 pieces with a diameter of 3.5 cm from each of the 45 samples, weigh their original masses G. respectively, use a Martindale wear resistance testing machine and set the number of rubs to 50,000 times, the mass of pressurized material is 395 g Convert the original quality value of the fabric to G2 based on the effective friction diameter of the fabricf, tested by the Martindale Abrasion Tester.

Sample via After rub 50,000 times on Martindale\'s wear-resistant testing machine, take it off, cut off the obvious hairballs on the surface of the fabric with scissors, and then quickly superheat it on the alcohol lamp several times to remove the hair on the surface of the fabric dust to be removed; cut off the effective friction diameter in the center of the fabric Round shape (can be cut along the track left by the fabric held by the Martindale Fabric Abrasion Testing Machine). Finally, the mass G of the fabric after friction is weighed and the actual wear rate G (%) is calculated.

6、Test Results

Put the actual wear of the sample Rate, and specify the number of times of wear and test conditions of the test.
