Multi-Functional Scratch tester For automotive interior materials

          Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).         Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured.         Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consum...

Reveal the standards for textile breathability testing and let you understand it in seconds!

 Reveal the standards for textile breathability testing and let you understand it in seconds! Breathability testing is a measure of how much gas can pass through a textile. However, there is no single "optimal" air permeability value, as it depends on the specific circumstances in which the textile is used. For example, if it is used to make sportswear, it is hoped that it has good breathability; if it is used to make insulating clothes or warm clothes, it is hoped that it can block the cold well. Therefore, when testing the air permeability of textiles, the purpose of using the textile must be clearly understood in order to obtain reasonable values. In order to accurately and quickly test the true breathability performance of a sample, specially designed and developed instruments must be used. Testing methods generally include: fabric thickness (Thickness), fabric density (Density), fabric water absorption rate (Water Absorption Rate), evaporation and mass transfer (Moistur...
