Influence of Cross-Linkers on the Wash Resistance of Chitosan-Functionalized Polyester Fabrics
Tanja Pušić, Tea Bušac, Julija Volmajer Valh
TL;DR
This study examines how cross-linkers affect the durability of chitosan on polyester fabrics after washing.
Contribution
The study reveals that chitosan on polyester is more wash-resistant without cross-linkers, contrary to expectations.
Findings
Polyester fabrics with chitosan but no cross-linkers showed better wash resistance.
Cross-linkers like BTCA and HEMA did not improve chitosan retention during washing.
Alkaline hydrolysis was used to enhance chitosan-polyester interaction.
Abstract
This study investigates the wash resistance of polyester fabrics functionalized with chitosan, a biopolymer known for its biocompatibility, non-toxicity, biodegradability and environmentally friendly properties. The interaction of chitosan with synthetic polymers, such as polyester, often requires surface treatment due to the weak natural affinity between the two materials. To improve the interaction and stability of chitosan on polyester, alkaline hydrolysis of the polyester fabric was used as a surface treatment method. The effectiveness of using cross-linking agents 1,2,3,4-butane tetracarboxylic acid (BTCA) and hydroxyethyl methacrylate (HEMA) in combination with ammonium persulphate (APS) to improve the stability of chitosan on polyester during washing was investigated. The wash resistance of polyester fabrics functionalized with chitosan was tested after 1, 5 and 10 washes with a…
