- Abstract
Lipase and cutinase enzymes were applied to non-circular cross-sectional polyester fibres. Reflectance and colour changes of the fibres were investigated under specific treatment conditions. The results indicated that lipase L0777 did not affect these fibres, regardless of time of treatment or changes in pH. With cutinase, pits on the surfaces of the fibres occurred when cutinase was applied at 55°C and pH of 7.00 and 8.50, respectively, for 24 hours. This was demonstrated by reflectance and colour changes, as well as by SEM images. The wide-angled x-ray diffraction (WAXD) curves of the cutinase-treated fabrics were ambiguous in that the small changes may have been the result of heat rather than enzyme treatment. Differential scanning calorimetry (DCS) results for both untreated and cutinase-treated polyester fibres showed obvious changes. The peak at 250°C did not change but that at 265°C increased in area, indicating re-crystallisation.
