In this research work, we report the synthesis of novel biodegradable synthetic thickener able to provide good quality prints with reduced wastewater pollution. Biodegradable triglyceride polylactic acid (TGPLA) star polymer hydrogel was prepared via one-pot reaction by direct polycondensation of lactic acid and glycerol. The chemical structure of the produced polymer was determined by Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (1H-NMR), and gel permeation chromatography (GPC). The rheological properties of the novel thickening agent of different ratios of LA and GL were investigated. The use of such thickening composite in printing a variety of fabrics (polyester, wool, acrylic and nylon) with different types of dyes including (reactive, acid, basic, disperse, and metal complex) was described. In addition, the chemical oxygen demand (COD) and biological oxygen demand (BOD) were described.
