Comfort properties of nano-filament polyester fabrics: thermo-physiological evaluation

Comfort along with the aesthetic properties of textile clothing in activewear and sportswear are utmost worthwhile for costumer demand as latest trends. Different types of fibers and yarns are being used to improve the moisture management and comfort of the fabric for next to skin. Nowadays, multifilaments or nano-filaments of polyester with diameters in the range of a few nanometers and lengths up to kilometers are used in different range of important technological applications such as functional fabrics, biomedicine, composite, etc. Multifilament polyester yarns are made by aggregating many continuous filaments together characterized by their high tenacity and large surface area per unit mass. The nano-filament yarn has also significant effects on thermal comfort properties as a nano-filament fabric has less thermal conductivity than cotton fabric, but equal to multichannel polyester fabric while nano-filament fabrics gave the cool feelings with higher thermal absorptivity. Moreover,coolmax fabric showed the higher value of thermal resistance as compared to nano-filament fabrics. Nano-filament fabrics exhibited higher value of watervaporpermeability than cotton fabric.
