<p>A multi-layered non-woven hygroscopic fibrous textile material and method of making said material is disclosed. The fibres of the material extend across the thickness of the material and respectively opposite outer layers of fibres are fixed in a matted state relative to the inner fibres. The extent of matting is sufficient to increase thermal insulation per unit thickness relative to the inner fibres, whilst still permitting the outer layer fibres to allow air circulation between and through the outer fibres, to thereby permit moisture retention or release.</p> |
