Application of Reactive UV-absorbers for Increasing Protective Properties of Cellulose Fabrics during Standard Laundering Process

摘要

A number of water-soluble colourless fibre-reactive UV-absorbers derivatives of symmetrical triazine were used as additives during commercial laundering process. UV-protection factor (UPF) of such treated cotton tricot samples was measured. Changes in protection properties of modified textiles after repeated standard laundering process were determined. Carried-out experiments gave evidence of covalent bond formation between applied absorbers and cellulose fibre during standard washing process at 40 °C or 60 °C. Textiles modified by this method have provided UV-protective properties for prolonged time.
