Examples
Embodiment 1
[0185] (warp, weft)
[0186] Made of nylon 6·6, with a circular cross-section, a single fiber fineness of 6.5 dtex, a single fiber count of 72, a total fineness of 470 dtex, a strength of 8.5 cN / dtex, an elongation of 23.5%, and a boiling water shrinkage Ratio 6.0%, untwisted synthetic fiber multifilament as warp and weft.
[0187] (warp preparation process)
[0188] Using a beam warper, a tension of 0.1 gf (0.1 cN) / dtex was applied to the above-mentioned warp yarn per unit fineness, and wound up to obtain a warp beam. Then, using a paralleling machine, a tension of 0.15 gf (0.15 cN) / dtex was applied per unit fineness of the warp, and the warp beams were combined to form a woven warp beam.
[0189] (weaving process)
[0190] The above-mentioned weaving warp beam was hung on a water jet loom (WJL), and the above-mentioned weft yarn was used to weave gray cloth with a warp yarn density of 54.5 yarns / 2.54 cm, a weft yarn density of 55 yarns / 2.54 cm, and a width of 2.0 m.

Embodiment 2
[0197] (warp, weft)
[0198] The warp and weft yarns of Example 1 were used.
[0199] (warp preparation process)
[0200] In the same manner as in Example 1, a woven warp beam was prepared.
[0201] (weaving process)
[0202] The gray fabric was woven in the same manner as in Example 1.
[0203] (Processing process)
[0204] Each side of the greige is passed through an accumulator with 10 rotating rolls, an open width soaping type scourer with 18 rotating rolls and 2 non-rotating rolls, a hot air type scourer with 8 rotating rolls A processing machine consisting of a drying machine and an accumulator with 8 rolls, counting the rolls arranged between the accumulator and the scouring machine, etc., so that each side of the fabric is combined with a total of 70 rotating rolls and 4 non-rotating rolls. Except for roll contact, it carried out similarly to Example 1, and processed.
[0205] As shown in Table 1, the obtained airbag base fabric maintained good mechanical propert...
Embodiment 3
[0207] (warp, weft)
[0208] Using nylon 6·6, having a circular cross-sectional shape, a single fiber fineness of 3.5dtex, a single fiber number of 136, a total fineness of 470dtex, a strength of 8.5cN / dtex, an elongation of 23.5%, boiling water 6.5% shrinkage, untwisted synthetic fiber multifilaments were used as warp and weft.
[0209] (warp preparation process)
[0210] In the same manner as in Example 1, a weaving warp beam was prepared.
[0211] (weaving process)
[0212] Gray fabrics were woven in the same manner as in Example 1 except that the warp density was 54.0 yarns / 2.54 cm.
[0213] (Processing process)
[0214] In the same manner as in Example 1, the base fabric for an airbag was processed.
[0215] As shown in Table 1, the obtained airbag base fabric maintained good mechanical properties, and although it was a high-density fabric using circular cross-section yarns, the degree of cross-sectional deformation was large, resulting in a lightweight, thin texture...
