Breathable Fabrics and Comfort in Clothing

Biopolymer-based Stimuli-Responsive Polymeric Systems for Functional Finishing of Textiles

“…Textile fabrics with a higher WVT permeability allow the human body to provide cooling due to evaporation of sweat. If the resistance to water vapour diffusion is high, the moisture movement is impeded and discomfort sensation of dampness and clamminess may arise (Keighley, 1985;Huang & Qian, 2007). The main mechanisms of water vapour transport through textile layers are (Indushekar et al, 2005;Das et al, 2007): diffusion of water vapour through the air spaces between the fibres; absorption, transmission and desorption of water vapour by the fibres; adsorption and migration of water vapour along the fibre surface (wicking); and transmission of water vapour by forced convection.…”

Tactile Comfort Properties of Thermal Protective Clothing in Static State

“…Middle layer is moisture barrier, which is composed of breathable waterproof material. It is generally known that breathable waterproof fabrics easily transport water vapor through the fabric structure while they have resistance to the passage of water [14]. The principle of this particular function is the enormous difference in size between water vapor molecules (approximately 0.4 nm in diameter) and rain droplets which usually exceed 100 m in diameter [15,16].…”

Numerical model of heat and moisture transfer in membrane material used for protective clothing against steam hazard

“…Membrane material, while possessing resistance to the transmission of liquid water, allows the penetration of water vapor through fabric structure [1]. The waterproof and breathable membrane can be used to improve thermal protective performance and thermal comfort of clothing, which is determined by heat and moisture transfer in it.…”
