Estimation of filtering properties of knitted materials made from functional thread

At present, textile filters of various structures are widely used, the main task of which is to ensure minimum dust and gas emissions in order not to exceed the maximum permissible concentration of harmful substances in the air. Structures of knitted filter materials using functional threads have been developed to minimize the emission of various pollutants into the atmosphere. Research has been carried out on the filtering properties of textile materials, such as dust holding capacity, and dust permeability, in order to identify the optimal weaving, raw material composition and method of heat treatment of fabrics that provide high efficiency of cleaning gas - air mixtures from fine dust.
