Introduction

With the progress of China's electronics, semiconductor, aerospace, precision instruments, pharmaceuticals and other high-tech industries, the rapid development of clean clean room technology the role of chambers of clothing has become increasingly prominent.

And other tests than the tiny particles of pollution (particle size less than 5µm) different methods, the method focuses on clean clothes shedding large micro Particles and fibers. Cleanroom clothing during use, easy off clothing once large particles fall down from the clothing, it will become clean room Pollutants inside. Detection and control of clean clothes shedding large number of particles, to ensure the quality of the clean room is of great significance.

Shedding large particle cleanroom clothing, including short fiber easy to fall off of. Morphology of fibers and particles generally have a greater difference, so Needs were detected.

Easy to fall off a variety of factors cleanroom clothing denser particles, depending on the clothing materials, processing and cleaning. Cleanroom garments the production process is not carried out in a clean environment, and good clean room garment sewing more attached to microparticles need to carefully cleaned Later, to meet the needs for use in a clean room. This standard is the result of the detection object cleaned clean packaged cleanroom clothing, detection Work does not include cleaning.
