Sealing tape and textile product using the same
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.
1. 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 (CF total ) 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:
CF total =CF m +CF t
CF m =√{square root over ( F m )}× D m
CF t =√{square root over ( F t )}× D t [Formula 1]
CF m : cover factor of the warp
CF t : cover factor of the weft
F m : fineness (dtex) of the warp
F t : fineness (dtex) of the weft
D m : density of the warp (counts/2.54 cm)
D t : 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.
2. The sealing tape according to claim 1 , wherein at least one of the cover factor (CF m ) of the warp and the cover factor of the weft (CF t ) is in a range from 200 to 800.
3. The sealing tape according to claim 1 , wherein a fineness of the filament is 12 dtex or less.
4. The sealing tape according to claim 1 , wherein at least one of the warp and the weft constituting the woven fabric is a textured yarn.
5. The sealing tape according to claim 1 , wherein the woven fabric has a plain weave construction.
6. The sealing tape according to claim 1 , wherein the polytetrafluoroethylene film has a hydrophilic resin layer on a side to which the adhesive layer is laminated.
7. The sealing tape according to claim 1 , wherein the hot melt adhesive is a polyurethane resin.
8. The sealing tape according to claim 1 , wherein the adhesive layer has a thickness of 120 μm or less.
9. The sealing tape according to claim 1 , wherein the sealing tape has a 10% modulus of 10 to 50 N/cm along a length direction thereof.
10. A textile product prepared by sewing a fabric laminated product, wherein at least a part of the sewn part is subjected to a sealing treatment with the sealing tape according to claim 1 .
11. The textile product according to claim 10 , wherein the textile product is a garment.
12. The textile product according to claim 10 , wherein the fabric laminated product comprises a flexible film, a woven fabric laminated to one side of the flexible film, and a cloth laminated on another side of the flexible film, wherein the woven fabric has a total cover factor (CF total ) of from 700 to 1400, calculated from the cover factors of a warp and a weft constituting the woven fabric according to a following formulae, and wherein the woven fabric side of the fabric laminated product is subjected to the sealing treatment
CF total =CF m +CF t
CF m =√{square root over ( F m )}× D m
CF t =√{square root over ( F t )}× D t [Formula 2]
CF m : cover factor of the warp
CF t : cover factor of the weft
F m : fineness (dtex) of the warp
F t : fineness (dtex) of the weft
D m : density of the warp (counts/2.54 cm)
D t : density of the weft (counts/2.54 cm).
13. The textile product according to claim 12 , wherein at least one of the cover factor of the warp (CF m ) and the cover factor (CF t ) of the weft is in a range from 300 to 800.
14. The textile product according to claim 13 , wherein the flexible film is a waterproof and moisture-permeable film.
15. The textile product according to claim 12 , wherein the flexible film is a waterproof and moisture-permeable film.
16. The textile product according to claim 15 , wherein the waterproof and moisture-permeable film is a porous polytetrafluoroethylene film.
17. A textile product prepared by fusing a fabric laminated product, wherein at least a part of a fused part is subjected to a sealing treatment with the sealing tape according to claim 1 .
18. The textile product according to claim 17 , wherein the textile product is a garment.
19. The textile product according to claim 17 , wherein the fabric laminated product comprises a flexible film, a woven fabric laminated to one side of the flexible film, and a cloth laminated on another side of the flexible film, wherein the woven fabric has a total cover factor (CF total ) of from 700 to 1400, calculated from the cover factors of a warp and a weft constituting the woven fabric according to a following formulae, and wherein the woven fabric side of the fabric laminated product is subjected to the sealing treatment
CF total =CF m +CF t
CF m =√{square root over ( F m )}× D m
CF t =√{square root over ( F t )}× D t [Formula 2]
CF m : cover factor of the warp
CF t : cover factor of the weft
F m : fineness (dtex) of the warp
F t : fineness (dtex) of the weft
D m : density of the warp (counts/2.54 cm)
D t : density of the weft (counts/2.54 cm).
