Abstract
The present invention provides a layered product, which, when processed into a textile product by sewing, fusing, or the like, overcomes such a practical restriction that a knit must be used on the side to be subjected to a sealing treatment, makes the sealing treatment easier, has intact appearance and touch feeling, and is lightweight. The layered product comprises a flexible film and a woven fabric layered thereon at the side to be subjected to the sealing treatment in processing the layered product into the textile product. The layered product has a total cover factor (CFtotal) from 700 to 1400, calculated from the cover factors of the warp and the weft constituting the woven fabric. CFtotal=CFm+CFt CFm: cover factor of warps CFt: cover factor of wefts
Claims23
A layered textile product comprising:
- a flexible film;
- a woven fabric laminated on the flexible film;
- and
- a sealing tape comprising a hot melt resin on a surface of said woven fabric, said sealing tape covering a sewn portion of said layered textile product,
- wherein said hot melt resin is impregnated into said surface of said woven fabric, and
- wherein the woven fabric has a total cover factor (CFtotal) from 700 to 1300, calculated from the cover factors of the warp and the weft constituting the woven fabric, according to the following formula:
- CFtotal=CFm+CFt
- CFm=√{square root over (Fm)}×Dm and
- CFt=√{square root over (Ft)}×Dt, wherein
- CFm:
- cover factor of the warp
- CFt:
- cover factor of the weft
- Fm:
- fineness of the warp (dtex)
- Ft:
- fineness of the weft (dtex)
- Dm:
- density of the warp (counts/2.54 cm) and
- Dt:
- density of the weft (counts/2.54 cm).
A layered textile product comprising:
- a flexible film;
- a woven fabric laminated on the flexible film;
- and
- a sealing tape comprising a hot melt resin on a surface of said woven fabric, said sealing tape covering a sewn portion of said layered textile product,
- wherein said hot melt resin is impregnated into said surface of said woven fabric,
- wherein the woven fabric has a total cover factor (CFtotal) from 700 to 1300, calculated from the cover factors of the warp and the weft constituting the woven fabric, according to the following formula:
- CFtotal=CFm+CFt
- CFm=√{square root over (Fm)}×Dm and
- CFt=√{square root over (Ft)}×Dt, wherein
- CFm:
- cover factor of the warp
- CFt:
- cover factor of the weft
- Fm:
- fineness of the warp (dtex)
- Ft:
- fineness of the weft (dtex)
- Dm:
- density of the warp (counts/2.54 cm) and
- Dt:
- density of the weft (counts/2.54 cm),
- wherein at least one of the warp and the weft constituting the woven fabric is made of two or more filaments and the fineness of the filament is at least 5 dtex,
- wherein the woven fabric has a construction selected from the group consisting of a twill weave, a satin weave, a plain weave and a rip-stop weave.
