Abstract
In this study, smart stimuli responsive cotton fabric was tailored by incorporation of temperature and pH responsive hydrogel with two different hydrogel particle size ranges, namely microgel and nanogel. Both hydrogels were based on temperature responsive poly(N-isopropylacrylamide) (poly-NiPAAm) and pH responsive chitosan (PNCS hydrogel). Hydrogels were incorporated onto cotton fabric, in order to study the influence of hydrogel particle size on the stimuli responsive properties, as well as morphological and chemical changes. Regardless of hydrogel particle size, improved air and moisture management activity of the functionalised fabric was achieved. Reduced size of nanogel somewhat influenced swelling ability of the functionalised fabric, although regardless of 4-times smaller concentration of applied hydrogel, comparable responsiveness and great decrease of stiffness was achieved.
