FIELD: chemistry. n SUBSTANCE: invention relates to chemical engineering of fibre materials and to fluorescent fibre, use thereof and methods for production thereof. Reclaimed cellulose fibre contains red pigment inclusions and a fluorescent dye deposited by subsequent colouring. The fibre satisfies EN 471 standards with respect to luminance factor, chromaticity coordinates and colour fastness, and is also characterised by light fastness greater than 5, measured according to ISO 105-B02, method 2. n EFFECT: invention enables to obtain fibre for use in protective clothes and clothes with reflecting properties, which satisfies the requirement for background materials in accordance with the EN 471 standard. n 11 cl, 2 tbl, 2 ex |
