1. Total number of particles in liquid environment (by simulation to test the total number of particles produced by the clean rag in the liquid environment, determine the adaptability of the rag in a clean environment), generally calculate the number of particles ≥0.5μm and ≥5μm, the unit Yes (million particles/m2), the smaller the particles, the better the performance of the rag.
2. Total number of no-load particles (measuring the number of empty particles released in a dry state in the case where a rag (or other material) produces a stress similar to the stress in actual use), generally calculating the total number of particles ≥ 0.5 μm ( Unit Particles/m2/ft3).
3. Number of fiber release (by measuring the total fiber load of the rag after receiving a certain amount of stress in the liquid environment (simulating actual use). Generally calculate the number of fibers > 100 microns, unit fibers / square meter.
4. Non-volatile residue test.
5. Adsorption capacity (adsorption speed and adsorption amount, the faster the adsorption speed, the larger the adsorption amount, the better the performance).
6, metal ion content.
As the core area of ​​the clean enterprise, the clean room is strictly controlled and fully qualified to enter, but most of the companies, including some experts, believe that as long as the non-woven fabric can meet the needs of the clean room, this view There is a big misunderstanding.
Non-woven fabrics are just a general term. The production environment of each rag manufacturing enterprise is uneven. Most of them are not produced in a strict clean environment. Such products are pollution sources. They are used to clean the environment and the effect is certainly not good. As for the self-made dust-free cloth towel, the soil method is even more unreasonable. It only cleans the dirt that can be seen by the eyes, but at the same time, it also creates more small particles to become a hidden danger affecting the quality of the product.
