Abstract

A method of producing synthetic threads and yarns which utilize a multicomponent structure having silver in an external sheath. The threads and yarns are then texturized via a false-twist process to increase the amount of silver available at the exterior surfaces of the threads and yarns. The resultant yarns and threads are also provided.

Claims (31)

1 . A multi-component filament comprising:

a core; and

a sheath, said sheath surrounding said core and including antimicrobial particles therein;

wherein said filament has been texturized by a false-twist process, said false-twist process increasing the amount of antimicrobial accessible at an exterior surface of said sheath.

2 . The filament of claim 1 wherein said core comprises Nylon.

3 . The filament of claim 1 wherein said sheath comprises Nylon.

4 . The filament of claim 1 wherein said core comprises polyester.

5 . The filament of claim 1 wherein said sheath comprises polyester.

6 . The filament of claim 1 wherein said antimicrobial particles comprise silver metal.

7 . The filament of claim 1 wherein said antimicrobial particles comprise silver glass.

8 . The filament of claim 7 wherein said silver glass comprises glass particles coated with silver.

9 . The filament of claim 7 wherein said silver glass comprises glass particles including silver nitrate.

10 . A filament bundle comprising a plurality of filaments of claim 1

11 . A filament bundle comprising:

a plurality of filaments, each of said filaments comprising:

a core; and

a sheath, said sheath surrounding said core and including antimicrobial particles therein;

wherein said filament bundle has been texturized by a false-twist process to increase the amount of antimicrobial accessible by a fluid in exterior surface contact with said filament bundle.

12 . The filament bundle of claim 11 wherein said core comprises nylon.

13 . The filament bundle of claim 11 wherein said sheath comprises nylon.

14 . The filament bundle of claim 11 wherein said core comprises polyester.

15 . The filament bundle of claim 11 wherein said sheath comprises polyester.

16 . The filament bundle of claim 11 wherein said antimicrobial particles comprise silver metal.

17 . The filament bundle of claim 11 wherein said antimicrobial particles comprise silver glass.

18 . The filament bundle of claim 17 wherein said silver glass comprises glass particles coated with silver.

19 . The filament bundle of claim 17 wherein said silver glass comprises glass particles including silver nitrate.

20 . A method of metalizing a synthetic filament bundle, the method comprising:

providing a plurality of synthetic filaments, each of said filaments comprising:

a core; and

a sheath, said sheath surrounding said core and including silver particles therein;

texturized said filament bundle by a false-twist process to increase the amount of silver accessible by a fluid in exterior surface contact with said filament bundle.
