Sažetak
Chitosan is an environmentally friendly agent used to achieve the antimicrobial properties of textiles. Due to the increasing demands on the stability of antimicrobial properties to multiple maintenance cycles, many authors are conducting research to permanently bind chitosan to the textile substrate. Aim of this study was to explore influence and persistence of the processing on cellulose textile substrates with an aqueous solution of chitosan using maleic acids in concentrations of 15 and 25 g/l with sodium hypophosphite monohydrate as catalyst. For the purpose of durability treated fabrics were washed according to ISO 6330:2012. The ability of maleic acid to crosslink chitosan with cellulose was tested before and after maintenance cycles using Fourier infrared spectrometry in the ATR technique (FTIR-ATR). The mechanical properties of the treated fabric were investigated before and after cycles of maintenance in accordance with ISO 13934-1. Maleic acid proved to be good crosslinking agent for chitosan and cellulose, regardless of applied concentration. The mechanical damage is higher in samples treated with a higher concentration of maleic acid due to the sensitivity of cotton to the action of acids.
