WebJun 18, 2024 · In order to solve the recycling problem of waste fibers, the nonwoven wall cloth was prepared with waste wool fibers and low-melting-point polyamide fibers as raw materials by combing into a net and hot-pressing method. The effect of fiber length, hot pressing temperature, mass fraction of the waste wool fibers, volume density, thickness … WebPrecision better than 1 µm. Thickness measurements of thin films, single-layer films, or multi-layer films. Films and film stacks: from 10 µm to several mm thick. The systems simultaneously measure the thickness of all substrates (including air gaps) within a film stack. High-speed scanning: acquisition of 2,100 to 100,000 points (profiles ...
