ABSTRACT:
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 lies 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.
