A sheath-core polyester fiber where the sheath includes an antimicrobial agent and the sheath comprises less than thirty percent of the total cross-sectional area of the fiber. The antimicrobial agent is selected such that the relative viscosity of the fiber ties above a defined spinnability limit, so that spinning is possible. With no loss in antimicrobial efficacy, the fiber of the present invention may be slickened with a siliconized finish in order to reduce fiber friction, thus giving the fiber a silky feel.

L'invention porte sur une fibre polyester âme/gaine dont la gaine comprend un agent antimicrobien et moins de 30 % de la totalité de la surface transversale de la fibre. L'agent antimicrobien est sélectionné de sorte que la viscosité relative de la fibre soit supérieure à une limite définie de filabilité et qu'il soit possible de réaliser le filage. Grâce à l'efficacité accrue de l'agent antimicrobien, il est possible de rendre la fibre lisse avec un fini siliconé de façon à réduire la friction de la fibre, et conférer à cette dernière un aspect soyeux.
