Abstract:

In this paper, the methodology of studies on the impact air-permeability of fabrics is presented. Stands for the static and dynamic investigation of textiles are described. A mathematical model of the pressure drop in a fabric resulting from the impact of air flow through the product has also been submitted. A measure of impact permeability in the form of an index for arranging fabrics with respect to their flow properties is given. Characteristic features of the structure of a woven fabric from a group of products of negative, positive and small index are shown.

Tags: impact air-permeability, impact permeability index, woven fabrics, air flow.
