The abrasion of the fabric refers to the phenomenon that the fabric is repeatedly rubbed between the fabrics or with other materials, and the fabric is gradually worn and damaged. The test principle of the abrasion resistance of the textile refers to the ability of the textile to resist abrasion under the action of repeated friction of mechanical force. During the use of the fabric, the fabric will be subjected to various external factors, especially the friction of the objects that are in contact with the surrounding objects, causing the fabric to be worn or damaged to varying degrees, affecting the performance of the fabric.

Testing the abrasion resistance of the fabric can improve the utilization efficiency of the textile and is an important indicator of the quality of the textile product. The abrasion resistance test of textiles is to cause the abrasion and wear phenomenon of textiles under repeated mechanical friction to be mainly damaged, lightened, faded, pilling and so on.

Textiles for different purposes have different requirements for wear resistance, and the methods of detection are different. There are many kinds of test methods for wear resistance, such as flat grinding, curved grinding, turning grinding, etc. There are two main methods commonly used: Martindale flat grinding method and Taber wear method.

一.Martindale flat grinding method

(1) Test equipment: There are many types of fabric flat grinding instruments. At present, the most used in the testing industry is the Martindale Abrasion Tester. Therefore, the flat grinding method is often called the Martindale wear-resistant method.

(2) Test principle: a circular sample installed in the sample holder of the Martindale Abrasion Tester, under the specified load, with the plane motion of the Lissajous pattern and the abrasive (ie standard fabric) Friction, the specimen holder is free to rotate about its axis perpendicular to the horizontal plane. The wear resistance of the fabric is determined based on the total number of times the sample is broken.

(3) Martindale Test method: During the test, a certain size of the test sample is brought into contact with the standard abrasive under the specified pressure, and the sample is moved relative to the abrasive by the Lisharu trajectory, so that the test sample is uniformly worn in multiple directions.

二、Taber wear method:

(1) Test equipment: Taber abrasion testing machine

(2) Test principle: pre-grinding 25 turns, the test sample is placed on the horizontal platform of the TABER wear tester, and the two grinding wheels are given a specific pressure pressure on the test piece. The axis of the grinding wheel is horizontal and horizontal. Parallel, one grinding wheel faces outward and the other faces inward, recording all changes of the test piece within a certain period of time.

(3) Taber Wear Test method: A sample having an outer diameter of 108 mm and an inner diameter of 8 mm was cut with a cutter. Then attach a hard sticker of the same size to the back of the sample. Place the sample center hole on the rubber pad of the screw, put the gasket on, and fix the sample with the compression nut. Then fasten the fixing ring and tighten the fixing ring screw with a wrench. Install two H18 grinding wheels on the support arm. Each grinding wheel applies a force of 250±10g to the tested sample, ensuring that the label side faces outward, so that the grinding wheel has a load of 500g, and the vacuum cleaner is connected to vacuum the vacuum cleaner. The pipe is connected to the joint on the left side of the machine to start the vacuum cleaner. Set the number of tests according to the standard and set the swing speed to 72 rpm. Then start the start button, start the instrument with a rotation speed of 60 ± 5 times / min, rotate horizontally, and test according to the required number of times. In the test, the surface of the sample was removed with a brush, the wear of the test was observed, the leather was ground to the specified end point, and the final number of revolutions was recorded.
