A New Constructed, Simple Device to Evaluate the Fabric Structural Parameters on Dust Retention

This article emphasizes the field of Environment Protection Technology, intending to provide a novel instrument that has been conceived and developed for the purpose of assessing filtration efficiency. This measurement is achieved by examining the interplay between the structural characteristics of clean cloth fabric, the parameters of the dust being filtered, and the factors involved in the testing process. Fabric samples used throughout the present study were woven cotton 100%, polyester 100%, and cotton/polyester 50/50%. The warp count is 30/2 for all fabric samples, the weft count is 9/1; 12/1; and 20/1. The weave of satin, basket, and twill is 3/1 with four different picks/cm to produce the fabrics with the same cover factor. For dust separation fabrics range in weight from “300 – 450 g/m2” with an air permeability of “100 - 300 l/d m2·min” at “196.2 Pa” (20 mm WG) as specified in DIN 53887.Air permeability through fabrics depends entirely on the sieving percent of the surface of the fabric, which is partly the pores and partly the permeability through the yarns, which are the basic elements of a fabric. The results showed that dust capturing depends entirely on air permeability, which is related to fabric weave structure and fabric material at specified testing and measuring variables.
