Preparation and Characterisation of Temperature Regulating Silk Cocoon Extract (Sericin)/PVA Based Smart fabric

Smart fabrics help to regulate body heat and provide thermal comfort to the body. Hence from many decades research on heat transfer analysis and temperature regulating wearable clothing takes important place. Hence, here we developed green, simplistic and economical sericin/PVA film using industrial waste sericin along with PVA. For this, the fabrication of sericin/PVA was carried out by employing polymer solution casting method and slow evaporation method by varying the sericin concentration by keeping PVA constant that is in the ratio of 2:1, 1:1. Characterization techniques like X ray diffraction, and UV visible spectroscopy were carried out and fluorescence effect were studied. This research showed that higher concentration sericin/PVA film can effectively absorb phonons of UV radiation and convert into fluorescence light thereby maintaining the temperature of the film/fabric. Hence this film/fabric can be used in industries where workers are constantly exposed to harmful UV radiations.
