Layered product and textile product comprising the same
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 (CF total ) from 700 to 1400, calculated from the cover factors of the warp and the weft constituting the woven fabric. CF total =CF m +CF t CF m : cover factor of warps CF t : cover factor of wefts
