Abrasion Resistance of High Performance Fabrics by the Martindale Method

Abrasion resistance of high performance fabrics by the Martindale method was done in accordance with the HRN EN ISO 12947-1: 2008, Textiles – Determination of the abrasion resistance of fabrics by the Martindale method, Part 1: Martindale abrasion testing apparatus, applicable for the testing of: · woven and knitted fabrics, · pile textiles having pile height of up to 2 mm and · nonwovens. The standard defines the requirements for the test apparatus according to Martindale and the auxiliary materials in order to determine the resistance of textile fabrics to wear. Martindale tester consists of the apparatus and accessories. The equipment is easy to operate, but requires additional time to prepare the samples and perform other preparation tasks. Martindale abrasion testing apparatus is designed to give a controlled amount of abrasion between fabric surfaces at comparatively low pressures in continuously changing directions. ISO 12947 consist of the following parts u

Features Of Thermal Conductivity Tester

Thermal Conductivity Tester   Features The constant pressure water tank outside the box using spray method, which is often we say that the electrostatic powder coating method, makes the chassis appearance of excellent quality, strong mechanical strength, anti-corrosion, no rust. The heating temperature of the furnace is high, and the 9 silicon carbon rods in the heating furnace are arranged equidistantly in the furnace box. During the test, the furnace is heated at the same time, which not only ensures the temperature balance of the furnace, but also can ensure that the temperature can be heated to 1200 ℃. Easy to achieve a stable water pressure, constant pressure water tank with the upper and lower water tank and 3 flow meter at the same time is used to control the size of water circulation flow, to achieve constant pressure conditions. Test time is short: routine test time 8-12 hours, saving manpower, material resources, time. The measuring range is large: the device can mea

Test Procedure of Dry Rubbing and Wet Rubbing by Crockmeter

Manual friction fastness tester is the most commonly used instrument for the textile industry to detect the color fastness of the fabric to dry and wet rubbing. The test procedures for dry rubbing and wet rubbing are as follow: Dry rubbing: Use the holding clamp to mount the specimen on the baseboard of the Crockmeter . The long direction of the specimen is parallel to the track of rubbing. Ensure the specimen lays  flat on the baseboard. Two tests are performed, one along the direction of the warp/length and the other of the weft/width. Mount a dry rubbing cloth flat over the end of the peg on the Crockmeter and hold it taut by means of the spring clip provided. Ensure that the rubbing cloth is not placed on the diagonal in the direction that the peg is moving. Rest the finger on the specimen, ensuring that the spring clip is not in contact with the test specim

Application of Wezenbeek Abrasion Tester

Wezenbeek abrasion tester is mainly used to test the transparent material and coating on the glass, the lens coating performance, in addition it can also be used to assess the organic coatings, plastics, metals and other materials, wear resistance samples fixed to the bottom of the sandwich fixture,  Sample surface exposed height of not more than 1mm.  Place a uniform depth of standard abrasive media such as quartz sand or alumina in the sand table The sandbox is moved back and forth in a specific drive drive to drive the abrasive media in the entire sand table.  This random scratches of the media can be used to simulate the wear and tear of the product in daily life  In addition, Taber oscillatory wear instrument also allows users to use liquid grinding slurry for wear and corrosion testing.  Buy the relevant accessories, the user can also lens “Bayer test”.  The purpose is primarily for comparison with the reference lens The test parameters of the  Taber Oscillation Meter  

Maintenance Matters Of Taber Abraser

 Wear test machine a lot of types, such as Martindale wear-resistant instrument, oscillatory wear-resistant instrument, wear-resistant instrument, universal wear tester, Taber wear test machine , etc., the following Taber wear test machine, Describe the use of wear testing machine and common faults. Taber abrasion tester mainly through the rotation of the grinding method, the use of different types of friction wheel on the sample rotation to detect leather and plastic materials such as wear resistance. Maintenance matters:    1. The instrument must be placed on a smooth ground before use;    2. Do not allow the use of the process of nail machine;    3. Select the appropriate power supply voltage, not too high, to avoid burning device;    4. In the event of abnormal equipment, please contact with the Secretary for timely processing;    5.
