Sažetak
It is known that alkaline hydrolysis of poly(ethylene-terephthalate) fabric (PET) improves the aesthetic appearance and comfort, but it is not environmentally friendly. Enzymes are biodegradable, non-toxic, degrade certain substance, reducing processing time and save energy. Since the possibility of adsorption depends on the number of available groups, the effects of PET fabric enzymatic hydrolysis were investigated in this paper. The lipase enzymes produced in the laboratory and a mixture of commercial lipases LipomodTM 299P i LipomodTM 29P from the company Biocatalysts were applied. The change in adsorption properties was monitored by adsorption of Fluorescent Brightener 135 – benzoxazole derivative applied in three concentrations and by the determination of moisture management ability on a Moisture Management Tester according to AATCC TM 195-2017. The results were compared with the untreated PET fabric and the reference sample (alkaline hydrolyzed PET fabric). From the results of spectral remission, fabric whiteness according CIE, tint deviation and tint value, the concentration of 1.2 % owf of optical brightener was determined to be optimal. Enzymatically hydrolyzed fabrics achieved slightly weaker adsorption and hydrophilicity effects than alkaline hydrolysis, but still significantly better than untreated PET fabric. The results of MMT, especially the values for Accumulative one way transport capacity (R), confirm that.
