Modeling convection/diffusion processes in porous textiles with inclusion of humidity-dependent air permeability

Functionalization of cotton with poly-NiPAAm/chitosan microgel. Part I. Stimuli-responsive moisture management properties

“…Since the size of the pores is far more important to moisture transfer than the hydrophilicity (Gibson and Charmchi 1997), it would be expected that at temperatures below transition point the presence of a higher concentration of PNCS microgel particles further decreases the pore size, thus allowing less vapour being transmitted through the fabric. Nevertheless, our study shows that the concentration of PNCS microgel (factor A) does not influence the responsive behaviour of functionalized cotton.…”

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

“…This affects the ability of the fabric layer in passing heat and water vapour, as fibre swelling reduces free air volume within the fabric, affecting both the convective and diffusive transport of energy and mass. The size of pores in the fabric is far more important to moisture transfer than the hydrophilicity of the fabric (Gibson & Charmchi, 1997). Cotton functionalized with the temperature responsive hydrogel which shows specific volume phase-transition (swelling and shrinking), represents a system that is able to control the evaporative rate at which a material can transport moisture vapour.…”

Effects of clothing and fibres properties on the heat and mass transport, for different body heat/sweat releases

“…The ranges considered in the analyses included values that are typical of textile materials (taken from literature) but also less common possibilities (e.g. regain values as high as 0.30 [39,51], or density values of 7850 kg m À3 [52] that are typical of ferrous metals), which enabled the study of different possibilities in terms of materials. Therefore, the possibility of using new materials to manufacture clothing was explored, which could result in products with improved thermal performance and/or new functionalities.…”
