Title
(EN) INCORPORATION OF ORGANIC ANTI-MICROBIALS INTO FIBRES DURING A FIBRE SPINNING PROCESS
(FR) INCORPORATION D'AGENTS ANTIMICROBIENS ORGANIQUES DANS DES FIBRES AU COURS D'UN PROCEDE DE FILATURE DE FIBRES
Abstract
(EN)
A process for finishing regenerated cellulose fibres with an anti-microbial and/or antifungal agent or a mixture thereof wherein in the first step, a formulation comprising an anti-microbial agent and one or more surface active agents are added to the soluble form of the fibres prior to regeneration and in a second step this mixture is extruded from a spinneret to form the regenerated fibre. The fibres treated according to the process of the present invention show good anti-microbial and antifungal activity.
(FR)
L'invention concerne un procédé de finition de fibres de cellulose régénérées, à l'aide d'un agent anti-microbien et/ou d'un agent antifongique ou d'un mélange des deux. Ledit procédé consiste à ajouter un agent anti-microbien et un ou plusieurs agents tensio-actifs à la forme soluble des fibres, avant leur régénération; et à extruder ledit mélange d'une filière, de sorte que la fibre régénérée soit formée. Les fibres traitées selon le procédé de l'invention présentent une bonne activité anti-microbienne et antifongique.
