Pore size is an important consideration when selecting the proper filter cloth for a particular application. The pore structure in a nonwoven may be characterised in terms of the total pore volume or porosity the pore size pore size distribution and the pore connectivity.

There is a huge difference between micrometres and nanometres. The PM 10 filtering efficiency of four of the selected masks ranged from 63 to 84. The pore size ratio data also illustrate that the pore in yarn account for 333 of that in fabric suggesting that the pore in yarn has a certain impact on the wicking behavior of fabric.

That is the gold standard On surgical masks the pore size is bigger so more particles can go through but since they are 2-ply the two layers work together to trap a sizeable portion of viral. J Textile Sci Eng 7. The grade makes all the difference in cheese cloth thus explaining the varying cheesecloth uses.

The pore size of masks ranged from 80 to 500 μm which was much bigger than particular matter having diameter of 25 μm or less PM 25 and 10 μm or less PM 10 size. The pore size or mesh width is one of the parameters for the degree of filter efficiency. Pore size is determined by the number of fibers fiber size and the type of weave.

Pores with an internal width of less than 2 nm are referred to as micropores those with an internal width between 2 nm and 50 nm as mesopores and those larger than 50 nm are called macropores See Figures 2 and 3. Dust mite fecal matter andor body parts we dont actually breathe in whole dust mites are as large as 10 microns. The filter cloth edges can consist of fabric edges eg.

Cottonpolyester blends are in the middle when it comes to pore sizes. A layer of the solids to be separated accumulates over time and thus builds up the filter cake.
