Abstract

A tape having a woven fabric and an adhesive on at least one side of the fabric. The woven fabric comprises polyester warp yarns and acetate weft yarns.

Claims

1. A hand tearable tape comprising a woven fabric having a first side and a second side, an adhesive on the first side of the fabric and a polymer coating on the second side of the fabric, wherein the woven fabric comprises polyester warp yarns and acetate weft yarns, wherein the polyester warp yarns are less than about 45 denier, wherein the fabric has a tensile strength of between 18 and 60 lbs/inch, and wherein the fabric and polymer coating are colored.

2. The hand tearable tape of claim 1, wherein the tape is a medical tape.

3. The hand tearable tape of claim 1, wherein the acetate weft yarns are between about 100 and 200 denier.

4. The hand tearable tape of claim 1, wherein the woven fabric has a plain weave construction.

5. The hand tearable tape of claim 1, wherein the woven fabric comprises between about 50 and 130 warp ends per inch and about 30 and 65 weft ends per inch.

6. The hand tearable tape of claim 1, wherein the adhesive is a pressure sensitive adhesive.

7. The hand tearable tape of claim 1, wherein the polyester warp yarns are monofilament.

8. The hand tearable tape of claim 1, wherein the polyester warp yarns are multifilament.

9. The hand tearable tape of claim 1, wherein the polymer coating is polyvinyl chloride or an acrylic.

10. The hand tearable tape of claim 1, wherein the fabric has less than 15% open area.

11. A hand tearable tape comprising a woven fabric having a first side and a second side, an adhesive on the first side of the fabric and a polymer coating on the second side of the fabric, wherein the woven fabric comprises polyester warp yarns and acetate weft yarns, wherein the fabric has a tensile strength of between 18 and 60 lbs/inch, wherein the fabric has less than 15% open area, and wherein the fabric and polymer coating are colored.

12. The hand tearable tape of claim 11, wherein the fabric has less than 10% open area.

13. The hand tearable tape of claim 12, wherein the polyester warp yarns are less than about 45 denier.

14. The hand tearable tape of claim 11, wherein the fabric has less than 5% open area.
