Abstract
Sealing Tapes adapted for bonding to a fabric laminated product are described herein. The sealing tapes exhibit a total cover factor of 1400 or less and exhibit a porous open structure having water resistance characteristics. In some embodiments, the sealing tape of the present invention comprises a base film and a woven fabric laminated on one side of the base film and an adhesive layer laminated on the other side of the base film.
Claims20
A sealing tape for a garment comprising:
- a base film comprising a porous polytetrafluoroethylene film,
- a woven fabric laminated on one side of the base film, and
- an adhesive layer laminated on another side of the base film,
- wherein the woven fabric has a total cover factor (CFtotal) of from 500 to 1400, calculated from the cover factors of a warp and a weft constituting the woven fabric according to the following formula:
- CFtotal=CFm+CFt
- CFm=√{square root over (Fm)}×Dm
- CFt=√{square root over (Ft)}×Dt [Formula 1]
- CFm:
- cover factor of the warp
- CFt:
- cover factor of the weft
- Fm:
- fineness (dtex) of the warp
- Ft:
- fineness (dtex) of the weft
- Dm:
- density of the warp (counts/2.54 cm)
- Dt:
- density of the weft of the woven fabric (counts/2.54 cm),
- wherein at least one of the warp and the weft constituting the woven fabric is composed of two or more filament materials,
- wherein an adhesive of said adhesive layer is a hot melt adhesive, and
- wherein said sealing tape seals a sewn or fused portion of a garment.
