Dry cleaning is a laundry method that requires garments to be completely free of dust and static electricity

 This is a laundry method that requires garments to be completely free of dust and static electricity. This process demands the highest level of precision, with extremely strict controls to ensure safety and effectiveness for industries such as electronics manufacturing, pharmaceuticals, food production, and healthcare…, where clothing must be free from dust, static electricity, and bacteria. 

What types of garments is cleanroom laundry applied to?

Cleanroom laundry is primarily used to wash clothing in cleanroom environments. The garments for cleanrooms are typically made from polyester and carbon fiber. These materials feature advantages such as lint-free properties, dust resistance, and excellent static electricity protection.

Quality

- Higher requirements for cleanliness, must eliminate all ultra-fine dust, and bacteria, and control dust particles smaller than 0.3 microns. For ultra-fine dust particles at 0.1 microns or 0.3 microns, only a specific number of items, ranging from 1,000 to 10,000 counts, is acceptable on clothing.

- Garments after washing must retain their functions (anti-static, dust-resistant, etc.).

- Regular cleanliness requirements may still leave some small dirt residue.

- Garments after washing may lose their functional properties.

Control

- There is a stringent quality control system in place to ensure cleanroom laundry standards: dust, bacteria, surface resistivity testing, etc.

- Regular checks on laundry water quality, laundry chemicals, and the cleanliness of garments after washing.

- No specific quality control system in place.

- Quality checks mainly rely on subjective observation.

Cleanroom laundry requires the use of specialized equipment and chemicals to control the washing process to the highest standard, ensuring compliance with the standards set by the Institute of Environmental Science and the quality assurance guidelines of the quality management authority.
