Abrasion testing is one of the item that many materials must be tested at present. It is also an important index to determine the physical properties of materials, so as leather abrasion resistance test.The main testing methods for leather abrasion resistance are the Gakushin Abrasion Method, the TABER Abrasion Method and the Martindale Abrasion Method. Gakushin Abrasion Testing Method To testing the degree of damage and decolorization of dyed leather used in shoe upper and lining leather after friction. The test method is to wrap the dry or wet white abrasion fabric on the friction head, then repeated friction on the test piece clamped on the test bench of Gakushin Abrasion Tester. Martindale Abrasion Method This method mainly used wear resistance of textile fabric and leather materials. It specifies Martindale Abrasion Tester for testing. A circular specimen, mounted in a specimen holder and subjected a defined load, is rubbed against an standard fabric in a translation movement tracing a LIssajous figure. The evaluation of the abrasion resistance of the textile fabric or leather is determined from the inspection interval to breakdown of the specimens. Taber Abrasion Method This method is complied with ASTM D3884.The principle:A specimen is placed on a rotating platform and rubbed by the sliding rotation of two abrading wheels. One abrading wheel rubs the specimen outward the periphery and the other, inward toward the center. Thus forming a circular wear mark. After the specified number of frictions, the resistance of abrasion of the sample is evaluated by appearance. Taber Abrasion Tester can simulate the real working conditions or meet the test conditions prescribed by the standard. Also can use different abrasive medium and accessories to do the different test.

Do you have any embarrassing situation in your clothing that has been broken by a sharp object? In real life, our clothes will be broken and torn when worn, which involves the problem of strong tearing of the fabric. Then what is the tear strength? Fabric tear Fabric tearing also referred to as tearing,fabric partial yarn is subjected to a concentrated load to tear the fabric apart. During the use of the fabric, the clothes are hooked by the object, partial yarn is pulled apart by force, so that the fabric forms a strip or a triangular crack, which is also a phenomenon of breakage. Tear Strength It can reflect the degree of catalysis of the finished fabric, so the tearing strength test is performed on the resin-finished cotton fabric and the wool-formed pure or blended combed fabric. Knitted fabrics are generally not subjected to tear test except for special requirements. How to judge if the tear strength of your clothes is qualified or not? There are many methods for the tear strength test: 1. Pendulum method 2. Pants type method (including single tongue method and double tongue method) 3. Trapezoid method 4. Wing method. The most common test method is the pant-shaped single tongue tear test. And how to test it? Cut the sample as belows picture shown according the standard required. Standard require each sample cut into two test sample. One is lengthways. The other one is crosswise. Each test sample should be included at least 5 pieces. Then on test. When the stressed yarn in the sample is separated up and down gradually, the yarn that is not directly stressed begins to have some relative sliding with the stressed yarn., and gradually draws closer to form an approximate triangular area, which is usually called the stressed triangle. Due to the effect of friction resistance between the yarns, the sliding is finite, that is, the number of yarn roots under stress in the triangle is limited.In the stress triangle area, the stress on the bottom edge of the first yarn is the largest, and decreases successively. When it is sliding, the tension of the yarn increases rapidly,  the elongation of the yarn also increases sharply. When the first yarn constituting the bottom edge of the force-triangle triangle is deformed to the elongation at break, the yarn breaks. Thereby a maximum value of a certain tear load is obtained. The next yarn then begins to become the bottom edge of the force triangle, so that the yarn of the non-pull system breaks one at a time to tear the fabric. Lastly, the calculating.the electronic calculation devices divides the first peak and the last peak into four regions,exclude the first region, and records all the peaks in the rest of three region. The average value was calculated and the tear strength of this sample was recorded. (The unit is indicated by N) Testing Equipment: GT-C01-1 Universal Tensile Strength Tester (Dual Column)

Folding resistance is one of the basic mechanical properties of paper, which is used to indicate the ability of paper to resist reciprocating folding. The folding resistance of the paper is the number of folds required to measure the stretch of the paper after being stretched by a certain force and then folded back and forth until the paper breaks.It is expressed in number of times, the unit is double fold.According to the longitudinal cutting, the test result is the longitudinal folding resistance; according to the transverse cutting, the test result is the transverse folding resistance. Generally, the longitudinal folding resistance is higher than the transverse folding resistance, which is due to the arrangement of the fibers and the high bonding strength of longitudinal fibers. Folding resistance is one of the important indicators of the mechanical strength of paper and paperboard. The folding resistance is very meaningful for reflecting the performance of the paper bag and the carton lining paper. Any paper that needs to be folded frequently when used generally has strict requirements on the folding resistance.

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 s...
