The present disclosure relates to an inflatable structure transformable between a deflated state and an inflated state, the inflatable structure comprising a drop stitch fabric having a first layer and a second layer tethered by drop stitches. At least one layer of the first and second layers comprises a ridge formed by a folded portion of the one layer, secured by a fixation line. The disclosure also relates to a manufacturing method of an inflatable structure in accordance with the foregoing, and an inflatable seat comprising such an inflatable structure.

A base fabric, having a coefficient of variation CV1 (100×standard deviation/average value) of 3.0% or less in a length direction of a weft-direction disintegrated yarn strength and a coefficient of variation CV2 (100×standard deviation/average value) of 4.0 or less in a length direction of a weft-direction disintegrated yarn elongation.

A safety airbag mesh, which includes a fiber layer. The fiber layer includes a warp fiber unit that extends warpwise and a weft fiber unit that extends weftwise, characterized in that the warp fiber unit includes a plurality of first fibers and second fibers arranged weftwise. The first fibers warpwise cover a buffer area and a support area, and the first fibers in the buffer area take on nonlinear formation, and extend longer than the second fibers in the area.

An air bag base cloth according to the present invention includes a base cloth main body formed of synthetic fibers, and a synthetic resin layer with which at least one face of the base cloth main body is coated, and the moisture content measured in accordance with JIS L 1096.8.10 is 0.5% or less.

Object:

Conventional woven fabrics mounted on a loom have a fabric length difference between the center portion and the sides of the woven fabric, which increases the flaring rate. In the scouring shrinkage step, yarns shrink and the crimp ratio is changed, which further increases flaring.

Means for achieving object:

The use of a bar temple with a ring function in the weaving process reduces protrusions. Further, by setting the boiling-water shrinkage rate of incorporated additional yarn lower than that of base yarn, the shrinkage of the sides of the fabric can be efficiently suppressed.

A heat resistant reinforcing cloth for an airbag is provided. The heat resistant reinforcing cloth can be disposed on an airbag part which contacts expansion gas in an airbag. The airbag can be deployed and expanded by expansion gas ejected from an inflator. The heat resistant reinforcing cloth comprises: a base fabric of natural fibers selected from the group consisting of cotton, hemp, flax, and combinations thereof; and a silicone rubber layer on both sides of the base fabric.
