A Wyzenbeek machine is used for the ASTM D4157-07 test allowing samples of the test fabric to be pulled tight in a frame. The Martindale Method for fabric abrasion tests is widely available in Europe and Asia. Unlike the Martindale test which moves in a circular motion, the Wyzenbeek moves in a linear motion creating a back and forth movement - also known as one 'Double Rub'. The Wyzenbeek Machine abrades the test fabric in two directions (image credit - Kravet blog) The Kravet Fabric blog describes the process: Abrasion resistance is "the ability of a fabric to resist surface wear caused by flat rubbing contact with another fabric." The end point is reached when two yarn breaks occur or when appreciable wear is reached or when 100,000 double rubs are reached. It is mostly used for upholstery fabric. It specializes in different methods of speci-men preparation including cutting, polishing and grinding. The test needs to stop when the fabric shows visible wear, two yarn breaks, or 15,000 double rubs, which is regarded as overintense for domestic purposes. No matter how it got named, the test became an industry-standard way of evaluating textiles. Wyzenbeek refers to the mecahnical test performed on fabrics to assess their durability and performance against abraison. TESTEX is one of the leading developers and textile testing equipment manufacturers since 2010, focusing on developing and manufacturing instruments used in textile industry all over the world. Double rubs are found through a mechanized test called So in simple terms, this means if there isnt any noticeable wear at the first check of 5,000 rubs but it shows noticeable wear at the next cycle it must be rated as only 5,000 double rubs. GenSalt is designed to test the surface of different materials for resistance to corrosion. The end point is determined when the subject fabric sample shows two consecutive yarns to have broken. It is well-known that this method is more accurate than the Wyzenbeek. enclosed Wyzenbeek. The machine provides a continuous direct readout for both the weight and the percentage moisture loss through the entire cycle. End use examples of heavy-duty installations where upholstery fabrics rated at 30,000 double rubs should be appropriate are single shift corporate, hotel rooms/suites, conference rooms and dining area usage. The machine is used to test the dyeing of the fabric, and the fade degree of the leather after dry or wet rubbing. The test method involves the specimen to be fastened to the base of the crocking meter and rubbed with an abrasive hammer attached to a wet or a dry cloth under controlled conditions. Suitable for single shift offices, conference rooms, There are two standard tests for woven upholstery abrasion resistance, also known as the rub rate: Martindale and Wyzenbeek.

Incorporate a pneumatic closed loop system for the automatic application of the axial pressure by a high performance pressure regulator, with the main advantage of eliminating the manual loading of the dead weights. The American Society of Testing and Materials (ASTM) acknowledges and accepts these two abrasion test methods. A Wyzenbeek machine is used for this test allowing sample of the test fabric to be pulled tight in a frame and help stationary. The abrasion tester is a four-station oscillatory machine designed to determine the durability of textiles and other manufacturing materials. This test determines the rate and magnitude of consolidation of a soil specimen restrained laterally and subjected to a number of successive increments of vertical loads. Whether youre determining the abrasion strength of stitched seams, leather, vinyl, fabric, textiles, or other materials, the Wyzenbeek abrasion test method is the ultimate solution. All of the fabrics on our website are measured using the Whereas the Wyzenbeek Test just measures back and forth abrasion, this test There are four working stations to support more samples at each testing time. This is essential for companies and manufacturers that focus on producing top-quality products with a longer lifespan. It is used to measure the ability of textiles to resist abrasion with the help of the oscillatory cylinder technique. It can conduct tests on a wide range of materials such as: cloth, paper, paint, plywood, leather, tile, glass, rubber etc. Since wear is always a result of abrasion, different test methods have been developed for the simulation of long-term wear.
