Description
Summary:Bio-wastes are organic materials achieved through biological sources. The rice crop produces a substantial amount of biowaste in the form of rice husk, which is rich in cellulose. In this research, cellulose was extracted from rice husk by alkalization and bleaching process. The rice husk extracted cellulose was further used to develop cellulose hydrogel by using the sol-gel technique. The nonwoven fabric of industrial cotton waste was developed in three different GSM (50, 100, and 150). The nonwoven fabric was incorporated in the cellulose hydrogel having three different concentrations (1 %, 2 %, and 3 %) to develop the hydrogel non-woven cotton fabric composite for sustainable wound dressing applications. Moreover, prepared rice husk extracted cellulose hydrogel loaded with AgNO3 (0.5 %, 1 %, and 1.5 %) for achieving antibacterial characteristics. The Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were employed to confirm the existence of cellulose hydrogel layers within the cotton nonwoven composite. The developed hydrogel S12 exhibited a maximum fluid absorbency of 1281.84 % with a tensile strength of 28.6 N and elongation of 40.96 %. The results show successful rice husk extracted cellulose hydrogel formation, exhibiting structural stability, excellent exudate absorbency and moisture management, antimicrobial efficacy, and sustainability.
