description	Applied to the textile manufacturing field, the present invention provides polymeric synthetic fibre compositions containing 0.25% to 4.00% lignin originating from the Kraft process, which are incorporated into the polymer by means of an extrusion process following the spinning process, through the use of a twin-screw extruder coupled to a spinneret. The fibres obtained are used in the production of textiles with anti-UV properties due to the presence of lignin, having greater strength, tear resistance and antioxidant activity of the fabric. La présente invention trouve une application dans le domaine de la fabrication de produits textiles, et concerne des compositions de fibres synthétiques polyères contenant de 0,25% à 4,00% de lignine provenant du procédé kraft, incorporées dans le polymère au moyen d'un procédé d'extrusion puis 'un procédé de filage, avec utilisation d'une extrudeuse à double filetage accouplée à une machine de filage. Les fibres obtenues sont utilisées dans la production de produits textiles possédant propriétés anti-UV du fait de la présence de lignine, et présentant une ténacité accrue, une résistance à la cassure supérieure et une meilleure activité anti-oxydante de maillage. Aplicada na área de fabricação de produtos têxteis, a presente invenção fornece composições de fibras sintéticas poliméricas contendo de 0,25% a 4,00% de Lignina proveniente do processo Kraft, que são incorporadas no polímero por meio de um processo de extrusão subsequente com o processo de fiação, pela utilização de uma extrusora dupla-rosca acoplada a uma fiadora. As fibras obtidas são utilizadas na produção de produtos têxteis com propriedades anti-UV devido à presença de Lignina, e com maior tenacidade, resistência ao estouro e atividade antioxidante da malha.
