1. Classification according to fiber thickness of cleanroom wipers
Polyester fiber lint-free cloth, microfiber lint-free cloth, sub-microfiber lint-free cloth, imitation ultra-fine fiber lint-free cloth, high-density lint-free cloth.
2. Classification according to the purification level of dust-free cloth:
Class 10 dust-free cloth, Class 100 dust-free cloth, Class 1000 dust-free cloth, Class 10000 dust-free cloth; according to the cutting and edge sealing technologies: cold cutting, laser edge sealing, ultrasonic edge sealing.
3. According to the functions of cleanroom wipers, they are classified as follows:
Nuclear industry dust-free cloth, radiation-proof dust-free cloth, photoelectric dust-free cloth, PCB dust-free cloth, anti-static dust-free cloth, conductive dust-free cloth, polishing dust-free cloth.
4. According to the product model classification of dust-free cloth, there are:
1009 series polyester fiber lint-free cloth, 2009 microfiber lint-free cloth, 3009 microfiber lint-free cloth, 3009A microfiber lint-free cloth, 4009 microfiber lint-free cloth, mf microfiber lint-free cloth, 4008 Sub-microfiber lint-free cloth, 5009 sub-microfiber lint-free cloth, 6009 sub-microfiber lint-free cloth, 7009 microfiber lint-free cloth, 8009 microfiber lint-free cloth, 1809 microfiber lint-free cloth, 9009 anti-static dust-free cloth, high-density microfiber dust-free cloth, etc.
5. According to the size and packaging of cleanroom wipers , there are:
There are three main specifications of commonly used lint-free cloths, and the conventional packaging is 9 inches, 6 inches, 4 inches, etc.
6. According to the classification of cleanroom wipers materials:
1. Full PP non-woven dust-free cloth: It is a good helper for removing oil stains, but its cleanliness is not high and its water absorption is not good.
2. PVA sponge lint-free cloth: It has a large absorption capacity and large decontamination capacity. It can only be used with water, otherwise it will be a hard block and cannot be wiped.
3. Polyester and brocade woven dust-free cloth: Advantages: Strong ability to remove residual glue and dirt. Disadvantages: Weak ability to remove granular dirt and dust.
4. PU sponge dust-free cloth: has a large capacity for removing dirt, but is not durable and is easy to break and shed fibers. And it is not resistant to strong solvents.
5. Cotton woven knitted dust-free cloth: high temperature resistance, strong ability to remove water pollution, very low cleanliness, not suitable for use in clean rooms above level 10,000.
6. Polyester knitted dust-free cloth: Advantages: wear-resistant, strong decontamination ability, high cleanliness. Disadvantages: It has no water absorption and weak ability to remove sewage. It is usually treated with a hydrophilic agent, and the hydrophilic agent will dissolve in the solvent we use.
7. Wood pulp/viscose and polyester composite non-woven dust-free cloth: Advantages: non-woven structure, strong macroscopic decontamination ability, suitable for removing a large number of pollutants. Disadvantages: The cleanliness is not high, the solvent breaks and falls off, and it cannot be used in a very clean environment.
8. All-polyester non-woven cleanroom wipers: It is cleaner and slightly more durable than wood pulp polyester non-woven lint-free cloth, but it is not suitable for removing water stains because polyester is not very hydrophilic.
9. Polyester and nylon knitted dust-free cloth: Advantages: Wear-resistant, strong ability to remove grease, fingerprints and other pollutants, the solvent dries quickly after wiping, and is highly efficient. Disadvantages: The cost is relatively high.
10. All-wood pulp non-woven lint-free cloth: Advantages: Resistant to organic solvents, strong decontamination ability. Disadvantages: Cleanliness is not high.
