How to distinguish the level or class of dust-free cleanroom wiper?

Dust-free cleanroom wiper refers to a cleaning cloth made of 100% polyester double-woven. The cleaning and packaging of its products are completed in an ultra-clean workshop, so it is called a cleanroom wiper. The surface of the cleanroom wiper is soft and can be used to wipe sensitive surfaces , friction does not take off the fiber, has good water absorption and cleaning efficiency.

Dust-free cleanroom wiper has a wide range of uses, mainly used for wiping high-tech products such as LCD, wafer, PCB, digital camera lens, camera film, and optical disc. It can not generate dust particles, and can also absorb liquid and dust particles to clean Function, mainly used in semiconductor production line chips, microprocessors, semiconductor assembly production, disk drives, composite materials, LCD display products, circuit board production lines, precision instruments, optical products, PCB products, laboratories, medical equipment, aviation industry And other clean workshops and production lines.

Types and characteristics of cleanroom wiper

There are many types of dust-free wipes, and different types of cleanroom wiper have different functions and characteristics. The main characteristics of cleanroom wiper are:

1. Polyester knitted wiping cloth

Features: Wear-resistant, strong decontamination ability, high cleanliness, but because it has no water absorption, the ability to remove sewage is weak, and it needs to be treated with a hydrophilic agent.

2. Polyester nylon woven wiping cloth

Features: The ability to remove residual glue dirt is strong, but the ability to remove granular dirt and dust is weak.

3. Polyester nylon knitted wiping cloth

Features: wear-resistant, suitable for removing grease, fingerprints and other pollutants, high cleaning efficiency and fast drying; the disadvantage is that the price is relatively high.

4. All wood pulp non-woven wiping cloth

Features: Resistance to organic solvents, strong decontamination ability, but the cleanliness is not high, and most products are prone to chipping, so it is only suitable for use in clean rooms below the thousandth class.

5. Wood pulp/viscose and polyester composite non-woven wipes
