Beschreibung
Zusammenfassung:	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. Aplicada en el campo de fabricación de productos textiles, la presente invención proporciona composiciones de fibras sintéticas poliméricas que contienen de 0,25% a 4,00% de lignina proveniente del proceso Kraft, que se incorporan al polímero a través de un proceso de extrusión posterior con el proceso de hilado, utilizando una extrusora de doble tornillo acoplada a una hilera. Las fibras obtenidas se utilizan en la produción de productos textiles con propiedades anti-UV debido a la presencia de lignina, y con mayor tenacidad, resistencia al estallido y actividad antioxidante de malla.
