How to test dust-free cloth and paper

How to test dust-free cloth and paper? For us, the difference between the dust-free cloth and the dust-free paper may only be the surface phenomenon of cloth and paper, but we may not understand how to detect them separately. Next, we will understand the detection methods of the dust-free cloth and the dust-free paper:

Test method of dust-free cloth:

1. The quality of the dust-free cloth depends on the thickness of the cloth. The heavier the weight is, the thicker the dust-free cloth is. Different products choose different weight of the dust-free cloth to wipe.

2. Pull both sides of the dust-free cloth by hand, and then look carefully at the light source with a magnifying glass to see if there is any torn fiber. The broken fiber will appear on the surface of the dust-free cloth in the form of cloth hair. The less broken fiber, the better the dust-free cloth.

3. Wipe the fingerprint or Chinese seal on your touch screen mobile phone with a dust-free cloth to see if it can be removed at one time

4. dip in alcohol and wipe your phone screen or glasses to see if they will leave stains and debris

5. Shake the dust-free cloth under the light in the dust-free room to see if a large number of debris will fall.

Test method of dust-free paper:

1. The main thing is to see if there is any paper scraps on the surface. Take it and rub it on your hand to see how little hair is lost.

2. Feel the hardness and thickness by hand.

Simple detection method refers to the emergency method which is usually used when there is no instrument and needs to be detected. Professional detection also needs professional equipment.
