How to distinguish the difference between ordinary cleaning cotton swabs and purification cotton swabs?

Purification cotton swabs, also known as dust-free scrubbing sticks, dust-free cotton swabs, are a kind of cleaning and scrubbing cotton swabs produced and processed in dust-free purification workshops with high cleanliness. The biggest difference between purifying cotton swabs and ordinary cotton swabs is the following three points: raw materials, functions, and advantages.

In terms of raw materials: the raw materials of dust-free purification cotton swabs/scrub sticks are divided into two types: sponge head and cloth head, both of which have been cleaned and packaged in a clean room, because the scrubbing consumables used in a high-grade dust-free environment must arrive Class 100 or above, only dust-free cotton swabs can meet the requirements, mainly used in HDD, PCB, FPD, lens, semiconductor and other industries to scrub attachments, dust and so on.
Advantage features:
a: Knitted nylon cloth (super wear-resistant)
b: Knitted microfiber (wipe fine dust, average wear resistance)
c: Woven microfiber (professional for fiber scrubbing)
d: Knitted polyester (the cloth surface is longitudinally grained, the gap is deep, and it can accommodate more dirt)
e : Non-woven head (low grade, but relatively less difficult to process and cheap)
The above clean cloth head cotton swabs can be used in class 100 clean room, suitable for electronic use. Sponge tip cotton swabs can be divided into the following two types according to the density of the sponge and the condition of crumb removal:
1: Open-pore PU sponge, 100PPI (PPI--PORE PER INCH, refers to the number of holes per inch, the more the number, the finer the sponge, and the less likely it is to drop chips). The sponge density is lower, and it is easy to drop chips, but Fast water absorption, suitable for medical use;
Two: Open-pore PU sponge, 400-500PPI, higher density than 100PPI sponge, less prone to chip removal, high dust-free level, suitable for electronic use.
