Synthesis and characterization of biocompatible hydrogel from textile–garment waste for personal hygiene products

Abstract

The objective of the present study is to synthesise cellulose-based hydrogel from cellulosic waste that is produced in the garment and textile industries. Carboxymethyl cellulose was synthesized via carboxymethylation subsequent to the separation of cellulose. The progress of reaction was monitored by measuring the degree of carboxymethyl cellulose substitution. Carboxymethyl cellulose was graft co-polymerized with acrylic acid and acrylamide in the presence of N,N-methylene-bis-acrylamide to develop a superabsorbent hydrogel. The generated hydrogel was put through several mechanical and physical tests, as well as FTIR, XRD, TGA and SEM investigations, to evaluate its real formation and characteristics. The prepared hydrogel demonstrated favorable swelling properties, as well as excellent adsorption of ions and dyestuffs. The maximum water absorption capability of the superabsorbent material obtained from textile and garment waste was 182 g/g. Furthermore, the prepared hydrogel exhibits exceptional biocompatibility, biodegradability, environmental friendliness, and non-toxicity. These qualities make it an exceptional material for use in personal care items and protective gear.
