The main aim of this paper is to look into the relationship between the structure and air
permeability of a woven fabric, and discuss the possibility of the prediction of fabric air
permeability. With respect to the relationship between the air permeability and structure of
woven fabrics it is not possible to describe fabric only by its porosity. Generally porosity in
-
dicates how many air gaps a textile material contains. For a description of airflow through
textile materials, further details about the configuration of pores in textiles (the pore size,
shape, texture, arrangement etc.) are very important. In this paper the influence of the type
of weave is eliminated by using only fabrics with a plain weave, where inter-yarn pores
have approximately the same shape. The size of these pores, however, varies considerably,
which has a significant influence on the air permeability of the fabric. This fact complicates
the possibility of the prediction of air permeability.
