How to choose clean clothing ESD fabrics with good dust filtration properties
Making a qualified clean garment not only requires the fabric to have good anti-static properties, but also has extremely high requirements for the fabric's dust filtration properties. So how to identify the dust filtering properties of fabrics?
1. Check the warp and weft density of the fabric
The latitude and longitude density of clean clothing is an indicator of the tightness of the fabric. The higher the latitude and longitude, the smaller the gaps in the fabric and the better the dust filtration performance.
2. Look at the linear density of the fibers used in the ESD fabric.
The finer the single fiber, the more total number of fibers arranged in the same area, the denser the woven fabric, and the better the barrier effect against particles.
3. Look at the fabric structure of the ESD fabric
Fabric weave refers to the interweaving of warp and weft threads in the fabric, generally divided into plain weave and twill weave. Clean clothes generally use 2:1 right twill, because the direction of this twill is consistent with the air flow direction during the air shower before entering the clean room, which is beneficial to removing floating dust on the clothes.
Of course, the dust filtration performance of the fabric is also closely related to the design and production process of the clean clothing. Therefore, to make a qualified clean clothing, it is very important to choose the fabric. The various styles of clean clothing produced by Tianjin Shili Company are strictly controlled according to the process and the fabrics used are inspected. The products comply with domestic and international standards.
