WIPO Patent Application WO/2022/255311
Kind Code:
A1
Abstract:
Provided is an upholstery material for a seat for vehicles, furniture, etc., wherein the material has excellent designability due to having concave deformed parts, and at the same time can suppress the occurrence of fluffing even if the surface is rubbed by hard protrusions such as hooks of hook-and-loop fasteners, and has excellent cushioning due to suppressing sideways falling. The upholstery material for a seat according to the present invention is constituted of a three-dimensional knitted fabric comprising a two-layered knitted fabric having a surface layer and a back layer, and a connecting thread that connects the layers of the two-layered knitted fabric, and the upholstery material is characterized in that the three-dimensional knitted fabric has concave deformed parts on the surface-layer side, and a parameter A, calculated by the formula: parameter A = course density (course/2.54 cm) × concave part thickness (mm) / fabric thickness (mm), is 6–36 (inclusive).
