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.

Description

field of invention

[0001] The present invention relates to sheath-core polyester fibers having antimicrobial properties, and more particularly to fibers wherein the sheath contains an antimicrobial agent and comprises less than 30% of the total fiber cross section. Background of the invention

[0002] We are surrounded by all kinds of microbes that, in some cases, can interfere with our ability to live healthy lives. Microorganisms that exist in our clothes are able to proliferate rapidly due to the favorable conditions provided such as temperature, humidity and various nutrients. Accordingly, there is a continuing desire to provide fibers with antimicrobial activity to protect the user and the fibers while doing so economically. For simplicity, the term "antimicrobial" is used herein to collectively refer to antibacterial, antifungal, and other such activities.

[0003] Proprietary antimicrobial acrylic and acetate fibers are currently commercially available. However, si...
