Conclusions
A directly proportional dependence of the air-permeability of heat-bonded fibrous materials from the aerodynamic spinning method on fibre diameter has been found, plus an inverse proportionality on the cloth thickness, wherein the cloth thickness exerts a greater effect on air-permeability.
The fundamental possibility of predicting the air-permeability of heat-bonded fibrous materials from the aerodynamic spinning method having a known fibre diameter and cloth thickness has been shown, and also the possibility of preparing materials with an assigned air-permeability by regulating the ratio of fibre diameter to cloth thickness.
