Abstract

An antimicrobial cloth formed of multiple layers of antimicrobial non-woven fabric that are stitched together with a silver thread. The antimicrobial non-woven fabric is formed of antimicrobial fibers and polyester fibers, and set into shape by a hot press to have the polyester fibers be melted and bonded to the antimicrobial fibers.

Claims

1. An antimicrobial cloth comprising multiple layers of antimicrobial non-woven fabric, and a silver thread stitched to said multiple layers of antimicrobial non-woven fabric, said multiple layers of antimicrobial non-woven fabric each being formed of antimicrobial fibers and polyester fibers, said antimicrobial fibers having a melting point higher than said polyester fibers.

2. The antimicrobial cloth as claimed in claim 1, wherein said multiple layers of antimicrobial non-woven fabric each are formed of 80˜

85% antimicrobial fibers and 15˜

20% polyester fibers.

3. The antimicrobial cloth as claimed in claim 1, wherein said silver thread is comprised of a conducting core and a silver covering surrounding the periphery of said conducting core.

4. The antimicrobial cloth as claimed in claim 3, wherein said silver thread is extruded from a compound of PET (polyethylene terephthalate) and silver powder.
