Stimuli responsive hydrogels (SRHs) are smart materials with reversible changes in their properties through the environmental stimulus variations. Although SRHs have been used in various medical applications such as sensors, drug release systems and, etc., they are still being actively researched on other sectors such as functional textiles and smart clothing. One of the best methods to produce textiles with more functionality is smart finishing of textile by surface modifying stimuli responsive hydrogels. In this paper, literatures on SRHs applications, methods and application of some SRHs on textile have been thoroughly discussed  

Cotton fabrics have been prepared with smart properties by functional finishing with stimuli-responsive nano gel. A biopolymer (chitosan) and a synthetic polymer (poly-NiPAAm) have been used for the synthesis of nano gel through semi-batch surfactant-free dispersion polymerization (SB-SFDP) method. The incorporation of nano gel to textile fabrics is achieved by pad-dry-cure procedure, using an aqueous nano gel dispersion and 1,2,3,4-butantetracarboxylic acid as a crosslinking agent. With this cross linking method, it is possible to integrate the nano gel into the cotton fabric’s structure with good resistance to washing. The changes in physiological comfort parameters of cotton fabric such...
