    摘要： In a skin material (10), a front face of a first fibrous base material (20) is a first color and a front face of a second fibrous base material (30) is a second color. The second fibrous base material (30) is laminated on a back face of the first fibrous base material (20). A through hole (22) of the first fibrous base material (20) penetrates the first fibrous base material (20) in a laminating direction. A dimension of the through hole (22) in a first direction is set to a first value (N1). A dimension of the through hole (22) in a second direction is set to a second value (N2). A dimension of the through hole (22) in the laminating direction is set to a third value (N3). The first value (N1) and the second value (N2) are set to be 0.38 times or more and 12 times or less with respect to the third value (N3).

    摘要： [Problem]
    Provided is a circular knitted fabric that has a good balance in elongation between a wale direction and a course direction, and also a knitted pattern.
    [Solution Means]
    A circular knitted fabric having a 1×1 rib jacquard knitted structure as a basic structure, in which non-elastic fiber yarn and elastic fiber yarn are fed as a full set and are plate-knitted, knit-loops account for 10 to 90% of all structures, and at least any one of a tuck and a welt is included so that a knitted pattern is formed on a knitted fabric surface due to a difference between structures by location, elongation in each of a wale direction and a course direction is 100 to 280% under a load condition of 14.7 N/2.54 cm, and an elongation ratio, that is, (elongation in wale direction)/(elongation in course direction), is 0.5 to 2.0 under the load condition of 14.7 N/2.54 cm.

    摘要： A non-coated air bag fabric is a fabric constituted by synthetic fibers, and the fabric has a cover factor of 2300 or more, a height difference between a recess and a protrusion on a surface of the fabric is less than 130 µm, and a P ratio expressed by the following equation is 0.85 to 1.15 inclusive. The P ratio = HP 100 /HP 80 where HP 80 indicates air permeability after a load is applied to the fabric under a condition of 80°C, and HP 100 indicates air permeability after a load is applied to the fabric under a condition of 100°C.

    摘要： A decorative sheet is caused to emit light from part of the front surface to improve the design features. A decorative sheet 1 according to an embodiment includes a first refractive index layer (high refractive index layer) 11 having a first refractive index, a decorative layer 14, a second refractive index layer (low refractive index resin layer) 12 that has a second refractive index lower than the first refractive index and is provided between the first refractive index layer and the decorative layer, and a light diffusion layer 15 that is provided in partial contact with one surface of the first refractive index layer and diffuses light entering from the first refractive index layer so that light is released from part of the front surface of the decorative sheet. A resin molded body 21 may be integrally laminated on the back surface side of the decorative sheet 1 to form a decorative molded article 2. In addition, the decorative molded article 2 may be provided with a light source 31 that injects light from the side surface of the decorative sheet 1 to form a decorative module 3.

    摘要： Provided is a fabric to which an uneven-surface design which is fine and has flexibility and wear resistance is imparted. The fabric has a polyurethane resin applied portion on at least a portion of a surface side of the fabric, and an uneven-surface design shaped on the polyurethane resin applied portion. The polyurethane resin applied portion is a region in which a polyurethane resin which is applied is present, and the polyurethane resin permeates between the fibers at least in a surface portion of the fabric such that a surface of the fabric is formed by the polyurethane resin and the fibers. In the polyurethane resin applied portion, an application depth of the polyurethane resin is 50 to 200 µm, a filling ratio of the polyurethane resin is 15% to 45%, and a filling ratio of the fibers of the fabric is 50% to 80%.
