A clean room rag is a rag developed for use in clean environments, including clean rooms.
A clean environment is an environment where standards are set for the number of particles (dust, dirt, etc.) per unit volume and the cleanliness is controlled. Ordinary rags such as rayon rags have a tendency to generate dust and dirt (dust emission) and cannot be used in a clean environment.
A clean room rag uses special fiber materials and manufacturing methods that reduce dust emission compared to ordinary rags. Many cleanroom rags are resistant to chemicals and solvents, have high liquid absorbency, and contain few impurities, making them suitable for use under severe conditions, such as in manufacturing processes.
The most important feature of clean room rags is their low dust emission. For this reason, it is used in fields where contamination or scratches caused by the slightest dust or dirt contamination can have a significant impact.
Specific application fields include the electronics industry, including semiconductors and disks, and the medical field. For example, in the case of disks, if foreign matter such as fiber waste is introduced during the manufacturing process, it can cause recording errors on the disk. The use of clean room rags for wiping during the manufacturing process can prevent such problems from occurring.
Ordinary rags are dust-generating. Fibers are a source of dust and dirt, so it is inherently difficult to suppress the dust emission of rags, which are textile products. As mentioned above, dust and dirt can degrade the quality of electronic products and pharmaceuticals, so rags with dust emission properties cannot be used in these manufacturing processes.
Rayon, acrylic, and polyester fibers are commonly used as raw materials for rags. Rayon and acrylic fibers are widely used, but these two types of fibers are known to have particularly high dusting properties. Polyester-based fibers are less dust generating than rayon and acrylic fibers, but they are more difficult to break than these softer fibers, resulting in the formation of fluff.
For this reason, clean room rags are made from other low-particulate fibers or by using special processes or manufacturing methods to improve the fibers, thereby reducing the dust emission of the rags. In many cases, polypropylene fibers are used because of their low dust emission, but some manufacturers use cotton fibers that have been made less dusty through a special manufacturing process.
