Professional explanation of clean clothing fabric parameters
Clean clothes belong to special functional clothing. Therefore, in the selection of clothing, you need to know the basic performance parameters of the product, such as the cleanliness parameters, how the dust filter performance, etc., about how to judge the dust filterability of the clean clothes fabrics, Tianjin strength technical staff After summarizing, the following answers are given.
1. Look at the warp and weft density of clothing fabrics. The warp and weft density is an indicator of the degree of tightness of the fabric. The higher the warp and weft density, the smaller the gap of the fabric and the better the dust filter rate. Through the warp and weft density mirror, the warp and weft density of clothing fabrics can be easily judged.
2. Look at the linear density (namely D number) of the fibers used in clothing fabrics. Generally speaking, the thinner the single fiber (the smaller the linear density), the more the total number of fibers arranged in the same area, the better the filling effect. The denser the woven fabric, the better the blocking effect of particles. Therefore, high-grade clean rooms generally use fabrics woven from filament fibers with a low linear density to make clean clothes.
3. Look at the fabric weave of the fabric Fabric weave refers to the interweaving of warp and weft in the fabric, generally in the form of plain weave and twill weave. Clean clothes should use 2:1 right twill, because the direction of this twill is consistent with the direction of airflow when entering the clean room, which is beneficial to remove the floating dust on the clothes. The density of the 2:1 twill is moderate and the filtering effect is better. . Under the same yarn and warp and weft density, plain weave is generally used in high-grade clean rooms because it is the most dense.
The dust filterability of anti-static fabrics is also closely related to the design of clean clothing styles and whether the use of accessories is reasonable. In addition, coating the fabric can not only increase the dust filterability of the fabric, but also make the treated fibers difficult to move and ensure the fabric The dust filtering effect will not drop rapidly due to washing.
