    Influence of pre-treatment in an alkaline medium on binding chitosan and 2,3-dihydroxy butandionic acid on cotton and polyester/cotton substrate
    (Wydawnictwo Politechniki Łódzkiej, 2022) Grgac, Sandra Flinčec; Milčić, Valentina; Vrbić, Ana
    The aim of this study was to investigate the binding success of chitosan to cotton and polyester/cotton materials via 2,3-dihydroxy butanedioic acid with prior leaching in 8% NaOH. Microwave energy was used in the preparation process, which due to its low energy potential, does not cause direct changes in the structure of the material but contributes to the speed of chemical reactions [1,3,4]. Samples were analyzed by spectroscopy with Fourier transform of infrared spectrum in the ATR technique. Determination of breaking force and elongation of the fabric was tested according to the HR EN ISO 13934-1:2013. The antimicrobial efficacy of all samples was tested according to the AATCC 147.
