The influence of lipase surface modification to polyester crystallinity and absorbility
Poly(ethylene-terephthalate) (PET) fabric has small absorption due to high fibre crystallinity. The alkali hydrolysis and aminolysis, conventional surface modifications, are not eco- friendly. Therefore, the alternative methods have been researched, and the application of enzymes is one of them. In this paper the lipase surface modification of light PET satin woven fabric was performed and compared to alkali hydrolysed one. The degree of crystallinity was calculated from the absorption on 973 cm-1 and 1018 cm-1 measured on FTIR-ATR, Spectrum 100, PerkinElmer. The liquid moisture management properties: Wetting time, Absorption Rate, Maximum Wetted Radius, Spreading Speed, Accumulative One-way Transport Capability, and Overall (liquid) Moisture Management Capability were determined according to AATCC TM 195-2017 Liquid Moisture Management Properties of Textile Fabrics on Moisture Management Tester (MMT M290 by SDL Atlas). It has been showed that lipase treatment lowers the PET crystallinity from 29.65 to 24.73%, similar as alkali hydrolysis 24.90%. The MMT results showed better absorption, moisture management, indicating better comfort of such treated fabrics
