Özet
A bioretanning agent was developed as an alternative to conventional synthetic retanning agents to pave the way for sustainability in the leather industry. Solid chromium shaving wastes from leather processing produced a proteinic sub-structure for the constitution building block of the bioretanning agent's backbone. The alkaline hydrolysis method was used to obtain the protein hydrolyzate, and the residual chromium content was determined as <80 ppm. The protein hydrolyzates were acquired in different molecular weights, and the hybrid biopolymers were obtained by grafting the hydrolyzates with acrylic acids (AAc) and acrylamides (AAm). To evaluate the properties imparted by the designed bioretanning agent, it was incorporated into the leather in the retanning processes and compared to the control samples fabricated with conventional procedures. As a result, penetration of hybrid biopolymer into the matrix for retanning was achieved easily, and using low and high molecular weight biopolymers have been recorded by 20% and 23% of improvement in the mechanical performance of the leather samples, respectively. Furthermore, the ratio of the hydrolyzate and AAm/AAc was found to be fitted at 1:2 for both. Furthermore, as per the evaluation of the leathers retanned by novel biopolymer, the results were promising in terms of technical viability and revealed that the biopolymer usage could enhance the mechanical performance of the leather while benefiting from the waste-to-wealth approach.
