This instrument is used to determine the appearance of textile fabrics after induced wrinkling. It is applied to both woven and knitted fabrics, made from any fibre or mixture of fibres. Materials which are insufficiently stable, for example those which are limp, thick or have a tendency to curl, can be assessed for wrinkle resistance with this device. The Wrinkle Recovery Tester (WRT) is used to determine easy care labels such as easy iron. A set of weights is supplied to permit compliance with ISO 9867, M&S P123, ENKA 3061 and AATCC 128.
