1. Before using the 5KN 10KN 20KN strength tester, check whether there is a reliable grounding device. 2. The voltage in the laboratory must be stable. It is best to install a voltage stabilizer in the laboratory. Do not use the Universal Testing Machine (Dual Column) when the voltage is unstable, so as to avoid short-circuiting and burning circuit boards due to unstable voltage. 3. When replacing...
Notice! There are new changes in the fuzzing and pilling rating regulations! Come see your fabric felt? With GB / T 4802.4-2020, ISO 12945-1: 2020, ISO 12945-2: 2020, ISO 12945-3: 2020, ISO 12945-3: 2020, ISO 12945-4: 2020, etc., the results of the above standard gaze rating also have Change. 1. The old standard requires the issuance of pilling levels, such as pilling Level 3; 2. The new version o...
Bursting strength is the most advanced method performed on fabrics to measure the strength of a material. It can be defined as the force required to break a woven/knitted fabric under standard conditions by a force applied perpendicular to the plane of the sample. Fabrics are often stressed in all directions during use, so it is necessary to apply actual stress to the material to determine the fab...
Spray Rating Tester is used to determine the water resistance of any fabrics, which may or may not have been given a water-repellent finish, to surface wetting by water. It is not intended to predict waterproofness, since it does not measure the penetration of water through fabric. 1.SAMPLE PREPARETION Cut off 3 180mm×180mm size smooth sample from the under-test fabric. Sample pre-conditioning: ta...
Manual Twist Tester is used to determine the number of twists of various yarns such as cotton, wool, hemp, and silk within a certain length to assess the quality of the product so as to correct the problems in the production process. Structure of Twist Tester for Yarn Picture 1 1. The structure is shown in the Picture 1. It is composed by the counting plate transmission gear, gripper, tension hamm...
The design of an instrument not only needs the accuracy of the test results, but also needs to pay attention to the operator's convenience of operation and the result review. Aveno combined the above points to design a Martindale Abrasion Tester that is easy to operate and review the results, and he uses precision components to precisely control the abrasion and pilling movement. The design princi...
