Significance and Use: Fabric Pneumatic Bursting Tester method for the determination of diaphragm bursting strength of knitted, nonwoven and woven fabrics is being used by the textile industry for the evaluation of a wide variety of end uses. universal testing machine compression test : tensile test generally involves clamping the two ends of the material sample on two fixtures separated by a certain distance. The two clamps separate and stretch the specimen at a certain speed. The change in stress on the sample is measured until the sample is destroyed. The tensile test of the tensile machine is one of the most widely used methods for studying the mechanical strength of materials, and it is necessary to use constant speed motion.

Correct use of computerized universal testing machine: Make sure all wiring is correct before the tensile testing machine is operated and preheat for at least 15 minutes to package the stability of the sensor. According to the test, the position of the upper and lower limit blocks is reasonably set to prevent the instrument from running over the stroke and causing damage to the fixture and the sample. When pressing the fast up button or the fast down button, do not put your hand between the moving beam and the fixed specimen, fixture or test device to avoid injury.

Testing to ASTM D4060 involves mounting a flat specimen to a turntable that rotates horizontally at a fixed speed. Two arms, each supporting an abrading wheel, are then lowered so that each wheel touches the surface. Before starting the test, a “suction arm” is lowered between the wheels to remove the abraded material from the sample’s surface. The turntable then starts rotating forcing rub-wear action of the wheels against the sample’s surface for the specified number of cycles or until a given mass of coating has been lost or until the wheels start exposing the substrate.

Gauge length and tension speed presettable; Able to set pre-tensile force; Many kinds of clamp are selectable according to requirements test standards, including pneumatic clamps. Textile fabric, such as bedsheets, clothes, etc., a lot of them will lose color after washing, some products fade seriously, even after washing many times, there will still be discolored. Test Preparation before Color Fastness to Washing. What test standards are there? Color fastness to washing is one of the common test items for textile dyeing fastness, which is mainly used to test the fastness of fabric clothing and home textile products after one or more times to simulate the dyeing after household washing and commercial washing. There are three common standard: AATCC 61, ISO 105 C06, GB/T 3921. Find extra details on
