Device for testing the properties of hair fibres

摘要

The present invention relates to a device (1) for testing the properties of fibre(s) (2), such as fiber-fiber friction or fiber strength. The fibres (2) may be human hair fibres, for example, a hair tress. The device (1) has a plurality of rods (3) that are capable of freely rotating. Each rod (3) has a proximal end (4) and a distal end (5). The proximal end (4) is connected to a support (6) via ball bearings (9). The distal end (5) is free. The present invention also relates to related uses and methods of using the device.
