martindale rub test chart
The standard wearability test used in the United States is called the Wyzenbeek test, also known as the "double-rub" test. How the Wearability Test Works . In this method, a special oscillating machine rubs the fabric in a rotating figure-eight pattern with a piece of worsted wool or a wire screen. Martindale Abrasion Tester(TF210), to determine the abrasion and pilling resistance of all kinds of textile structures. The double-rub testing method uses a special machine that passes a testing pad back and forth over the fabric until it is worn out. Domestic fabrics often have a rating of up to 20,000 rubs. ASTM D4966* Martindale The ASTM D4966 is a test method of the American Society of Testing and Materials (ASTM). Residential is usually between 10,000 to 25,000 … Commercial grade fabrics are usually rated at 100,000 to 250,000 double-rubs. Discover Clarke & Clarke. The test is also known as the Rub Test and it tests for abrasion. Each back-and-forth motion, or double rub, counts as one cycle. Standard Test Method for Abrasion Resistance of Textile Fabrics (Martindale Abrasion Tester Method) D4970 / D4970M - 16e3: Standard Test Method for Pilling Resistance and Other Related Surface Changes of Textile Fabrics: Martindale Tester: D5034 - 09(2017) Standard Test Method for Breaking Strength and Elongation of Textile Fabrics (Grab Test) Most fabrics undergo the Martindale Test to check their durability and suitability for various uses, i.e, curtains, domestic furniture, contract furniture. This is an oscillating test. The test methods include ASTM 4157-02 and ASTM D4966. Martindale Fabric Abrasion Tester will meet your needs when you do Martindale rub test. Martindale Rub Test: 30000: Country of Origin: Italy: Usage: Drapes, Upholstery - General Domestic: Clarke & Clarke, providing lively, fashionable designs, appealing to aspirational and fashion aware consumers. “The ASTM D4157-02 is a test of the American Society of Testing and Materials (ASTM). Fabric samples are mounted flat and rubbed in an eliptical motion using a piece of worsted wool cloth as the abradant and with 12 kPa of pressure. There are many methods of abrasion-resistance tests, of which the Martindale abrasion tester method (ASTM … Abrasion resistance is an important parameter in silk fabrics due to the fine structure of the silk filaments. A Wyzenbeek machine is used for this test allowing samples of the test fabric to be pulled tight … The number The test gives a score in 1000’s of rubs. During the test, the fabric is rubbed back and forth with a piece of cotton duck fabric. One test is the ASTM D4157-02 Oscillatory Cylinder (Wyzenbeek) test. Each back and forth pass is known as a double-rub. The holder, shown in Fig. P. Bhat, A. Basu, in Advances in Silk Science and Technology, 2015 7.4.1 Abrasion resistance test. This is an oscillating test. 7.11, takes a standard size 38 mm diameter sample which is held to size by a pinned ring. Mark an 8” x 1” area on the coated surface to test • Fold cheesecloth, of the proper type and grade specified in the standard, into a double thickness and saturate it to a dripping wet condition with specified solvent • Place index finger into center of cheesecloth and rub the test area at a 45° angle • A flattened rubber ball is pushed through … The Martindale Test (ASTM D4966) is an internationally recognized way to measure a fabric's abrasion resistance. Recently Viewed. Fabric samples are mounted flat and rubbed in a figure eight like motion using a piece of … The Martindale abrasion test ASTM D4966-98 is the method commonly used to predict wearability. This test makes use of a modified specimen holder for the Martindale abrasion tester, which stretches the knitted material thus effectively accelerating the test. In the 2010 version of ASTM D4966 the term movement was stricken and replaced by rub with a reference to ASTM D4850 Standard Terminology, Relating to Fabrics and Fabric Test Methods, where the terms Martindale Rub and Martindale Abrasion Cycle are explicitly defined. ... Order a paint chart. Martindale Test Equipment complies with ASTM D4966, ASTM D4970, ISO 12947, etc.
