Abstract
This article reports the results of breathability tests on upper materials, nonwoven insulation materials, lining materials, and material packs. The importance of air permeability values for packages of materials of thermal protective clothing for children diagnosed with cerebral palsy (CP) is substantiated. Objects and methods for studying the air permeability of materials are defined and described. The method according to State Standard ISO 9237–2013 was used to assess the properties of air permeability of materials. A method for calculating the predicted values of the air permeability of packages of materials is also given. The article analyses the results of air permeability of packages of materials obtained both theoretically and experimentally. The article compares the values of the air permeability of the packages of materials with the previous study of the packages of materials on the total thermal resistance. Conclusions are drawn about the requirements for air permeability of packages of materials for thermal protective clothing for children with cerebral palsy.
