摘要：
A composite sensor fibre comprises a filamentary core and an outer layer encapsulating an intermediate sensor layer of a detectably thermochromic liquid crystalline material. The outer layer is transparent and the filamentary core is configured to provides a contrast for facilitating the observation of temperature or temperature gradient changes in the thermochromic material. A fibrous material formed from the above described thermochromic composite sensor fibres is disclosed such as a fabric or clothing item. A dressing that includes a fabric having a matrix of the above described thermochromic composite sensor fibres which fibres indicate localised body temperature changes adjacent the dressing by visibly exhibiting a change in colour or colour gradient is also disclosed. A method of making a above described thermochromic composite sensor fibre comprises continuously delivering the filamentary core as a solid from a supply thereof and co-extruding the thermochromic liquid crystalline material about the core and the outer layer about the thermochromic liquid crystalline material at a temperature that facilitates the coextrusion but at which the core remains substantially solid and the outer layer does not substantially inhibit delivery of the thermochromic liquid crystalline material.
