Clean clothes and their use environment
1. Cleanroom clothing system (cleanroom clothing) In order to take away a large number of dust particles produced by the workers in the cleanroom and reduce the pollution of the cleanroom, a set of protective measures established for the individuals working in the cleanroom is that Dust-free clothing system. Generally consists of coveralls, boots, protective gloves, hoods, face protection and eye protection. The clothing system not only protects personnel but also processes and products. Therefore, the materials used must meet the following requirements: comfortable to wear and at the same time play a sufficient barrier between the wearer and the environment, wash and handle, suitable performance, contain anti-static fiber To reduce static electricity hazards.
2. The basic requirements and fabric characteristics of the dust-free clothing system. The purpose of using the dust-free clothing system is to minimize the human body’s dust pollution. Anti-static generation. In order to achieve such a protective effect, there are special requirements for the fabrics of dust-free clothing. Dust-free anti-static fabrics are also called anti-static ultra-clean fabrics, which are different from ordinary anti-static fabrics.
It must have the following characteristics at the same time:
A. It has an anti-static function to prevent clothes from being dusty and difficult to clean. At the same time, this anti-static performance must be durable and efficient, and will not be attenuated by daily washing and friction.
B. The fabric itself does not emit dust. Because it is worn in a clean room, it is required that the fabric cannot be the source of dust in the clean room. This determines that it can only be produced with chemically synthesized long fibers, and cotton, linen, silk, etc. Natural fibers cannot be used in ultra-clean fabrics.
C. It must have good dust filterability. The dust particles in the clean room mainly come from the indoor flowing air and moving human bodies. When the equipment conditions are determined, improving the cleanliness means that the tiny dust generated by the human body is required to be contained in the clothes to the greatest extent, and not to be emitted into the air. This is the so-called highest dust filter rate. However, increasing the dust filter rate comes at the expense of fabrics and air permeability, so loose fabrics are not suitable for clean rooms.
