The moisture management properties of laundered hospital textiles

The influence of repeated laundering to the change in moisture management properties of hospital protective textiles was researched in this paper. For that purpose, green cotton fabric for surgical gowns and white one for linen were subjected to repeated laundering according to ISO 15797:2017 up to 25 washing cycles. Washing procedures for white workwear and/or sensitive coloured trimmings – Peracetic acid (PAA) bleach were performed in Wascator FOM71 CLS machine at 75°C using Reference Detergent A1 with optical brightener by WFK. The physical-chemical properties were monitored on FTIR-ATR, Spectrum 100, PerkinElmer after 1st, 3rd and 25th cycle. The liquid moisture management properties were determined according to AATCC TM 195-2017 on Moisture Management Tester (MMT M290, SDL Atlas). It has been showed that hospital protective textiles contain finishing treatment, which removes during laundering, even after one washing cycle, changing the moisture management properties. Fabrics goes from water penetration, through moisture management to fast absorbing and quick drying fabrics. The MMT results indicate better comfort of such treated fabrics.
