Abstract: The present invention provides: an airbag cover which is formed by integrally joining a first base fabric and a second base fabric having mutually different characteristics, and has a joint portion that ensures high productivity in mass production; a method for manufacturing the airbag cover; and an airbag device. The present invention relates to an airbag cover for storing a bag-shaped cushion which is rolled up or folded before being inflated and deployed by a gas supplied from an inflater, and relates to a method for manufacturing the airbag cover. The airbag cover is characterized by comprising a first base fabric made of a plain-woven fabric or a non-woven fabric made from chemical fibers, and a second base fabric containing fibers different from the fibers constituting the first base fabric, and having an initial tensile resistance value higher than an initial tensile resistance value of the first base fabric.

Abstract: Provided is a cell characterized in that at least a part of a cell surface is covered by flame resistant fibers, and in that the flame resistant fibers are in direct contact with the cell surface and/or are separated from the cell surface.

Abstract: Provided is a sensing fiber member which can be processed in long lengths, which excels in mass production, which is supple and has an excellent texture, and which is much less costly than a contact sensing fiber member (a piezoelectric yarn) for which a conventional piezoelectric material is used. This sensing fiber member has at least two covering yarns for which covering is achieved by wrapping an insulating fiber serving as a covering material in one direction around a linear conductor constituting a core material, two of the covering yarns being arranged close to each other. The sensing fiber member is characterized by reading changes in resistance and/or changes in capacitance between the linear conductors of the two covering yarns arranged close to each other.

Abstract: Provided is a three-dimensional elastic circular knitted fabric combining light weight, heat retention, stretchability, and press shrinkage resistance. This three-dimensional elastic circular knitted fabric is obtained by connecting two front/back ground structures with a connecting yarn of only a tuck structure, wherein the three-dimensional elastic circular knitted fabric is characterized in that: the two front/back ground structures is solely constituted by non-elastic fiber; the connecting yarn is solely constituted by elastic fiber; the elastic fiber is interwoven at 2-15 courses/1 repeat; the loop density of the knitted fabric is 40-130 courses/inch, and 35-80 wells/inch; the filling rate is 5.0-25.0%; the thermal retention rate is 20.0% or higher; and the rate of elongation at a constant 22.1-N load is 50-200% in the warp direction and 150-300% in the weft direction.
