초록 ▼

An anti-microbial and/or anti-fungal synthetic fiber that comprises various thermoplastic polymers and additives in a bi-component form in either a core-sheath or side-by-side configurations. The anti-microbial synthetic fibers comprise inorganic anti-microbial additives, distributed in certain areas to reduce the amount of the anti-microbial agents being used, and therefore the cost of such fibers. The fibers can incorporate anti-microbial additives so that they are not removed by repeating washing in boiling water and in dry clean cycles and become ineffective and conversely enhance access to the additives by washing or the like. The fibers comprise high tenacity polymers (e.g. PET) in one portion and hydrolysis resistance polymers (e.g. PCT) in another portion with the additives. The fibers can further be blended with non-anti-microbial fibers such as cotton, wool, polyester, acrylic, nylon etc. to provide anti-microbial finished fabrics. In one such embodiment, binder fibers are used which are mixed with other fibers.

대표청구항 ▼

1. A bi-component fiber, comprising:(a) as a first component a core of PET having at least 30% and less than 70% of the fiber by weight, (b) as a second component a hydrolysis resistant PCT sheath surrounding the core having at least 30% of the fiber by weight and including an additive, (c) wherein the said additive comprises an anti-microbial/anti-fungal material in an amount ranging from 0.1% to 70% by weight of the fiber, and (d) wherein the thickness of the sheath is approximately two times the nominal particle size in microns of the additions.2. The fiber of claim 1, wherein said first component of high tenacity polymer is PET providing strength to the fiber, and said second complement of hydrolysis resistant polymer is PCT providing a hydrolysis resistant surface with good wrinkle resistance, and resistance to long term washings in boiling water and strong soaps.3. The fiber of claim 2, wherein the core is constructed to have a high modulus with properties of tenacity and elongation similar to cotton.4. The fiber of claim 2, wherein the core is constructed to have a low modulus with properties similar to wool.5. The fiber of claim 2, wherein the core is constructed to have an intermediate modulus fiber with properties between cotton and wool.6. The fiber of claim 1, wherein the additive is hydrophilic to create a fiber that, in a garment, appears to wick body moisture away from the skin and evaporate to create comfort to a wearer.7. The fiber of claim 1 wherein the additive is pigment to provide uniform colors that do not fade significantly over long-term use and washing.8. The fiber of claim 1, wherein the fiber size ranges from 0.7 dTex to 25.0 dTex.9. The fiber of claim 1, wherein said fiber is cut staple in lengths from 1.0 mm to 180.0 mm.10. The fiber of claim 1, wherein the fiber is continuous filament.11. The fiber of claim 1, wherein the additive is zeolite of silver.12. The fiber of claim 1, wherein said sheath is more than 28% of the cross section of the total fiber.13. The fiber of claim 1, wherein said additive particles are approximately 1 micron cubes and the sheath is approximately 2 microns thick.14. The fiber of claim 1 wherein the additive comprises a zeolite of a metal selected from the group consisting of silver, zinc, copper and tin.15. The fiber of claim 1 with one or more further functional additives in said sheath.
