次いで、経糸は糸１：糸２を３：１、緯糸は第１の糸１：糸２を２：１の割合で配して、織物密度が経１００本／インチ（２．５４ｃｍ）、緯７１本／インチ（２．５４ｃｍ）の綾織に製織し、目付２２０ｇ／ｍ２の織物を得た。糸１の経方向の間隔は１．１ｍｍ、緯方向の間隔は１．３ｍｍであった。熱暴露前後の経方向の引張強度、および熱暴露後の熱収縮率の測定結果を表１に示す。 Next, the warp yarns are arranged with yarn 1: yarn 2 in a ratio of 3: 1 and the weft yarns are arranged in a ratio of first yarn 1: yarn 2 in a ratio of 2: 1. Weaving was performed on a twill weft of 71 yarns / inch (2.54 cm) to obtain a fabric having a grain of 220 g / m 2 . The distance between the yarns 1 in the warp direction was 1.1 mm, and the distance in the weft direction was 1.3 mm. Table 1 shows the measurement results of the tensile strength in the warp direction before and after heat exposure and the heat shrinkage rate after heat exposure.
［実施例２］
実施例１において、経糸は糸１：糸２を９：１、緯糸は糸１：糸２を６：１の割合に変更する以外は実施例１と同様に実施した。糸１の経方向の間隔は２．３ｍｍ、緯方向の間隔は２．５ｍｍであった。
[Example 2]
In Example 1, the warp was changed to thread 1: thread 2 to 9: 1, and the weft was changed to thread 1: thread 2 to a ratio of 6: 1. The spacing in the warp direction of the yarn 1 was 2.3 mm, and the spacing in the weft direction was 2.5 mm.
［実施例３］
実施例１において、経糸は糸１：糸２を１８：１、緯糸は糸１：糸２を１２：１の割合に変更する以外は実施例１と同様に実施した。糸１の経方向の間隔は４．６ｍｍ、緯方向の間隔は５．５ｍｍであった。
[Example 3]
In Example 1, the warp was changed to the ratio of thread 1: thread 2 to 18: 1, and the weft was changed to the ratio of thread 1: thread 2 to 12: 1. The spacing in the warp direction of the yarn 1 was 4.6 mm, and the spacing in the weft direction was 5.5 mm.
［実施例４］
実施例１において、ポリメタフェニレンイソフタルアミド繊維（帝人社製「コーネックス」（商標名））とコパラフェニレン・３、４’オキシジフェニレンテレフタルアミド繊維（帝人社製、商標名：テクノーラ）とポリパラフェニレンベンズビスオキサゾール繊維（東洋紡社製「ザイロン」（商標名））とを混合比率が７０：２０：１０となる割合で混合した紡績糸（番手：３０／２）を糸１とする以外は実施例１と同様に実施した。
[Example 4]
In Example 1, polymethaphenylene isophthalamide fiber (Teijin's "Conex" (trade name)) and coparaphenylene 3,4'oxydiphenylene terephthalamide fiber (Teijin's, brand name: Technora) Except for the spun yarn (count: 30/2) in which polyparaphenylene benzbisoxazole fiber (“Zylon” (trade name) manufactured by Toyobo Co., Ltd.) is mixed at a mixing ratio of 70:20:10 to be thread 1. Was carried out in the same manner as in Example 1.
［比較例１］
実施例１において、糸１のみを用いて織物密度が経１００本／インチ（２．５４ｃｍ）、緯７１本／インチ（２．５４ｃｍ）の綾織に製織する以外は実施例１と同様に実施した。
[Comparative Example 1]
In Example 1, the same procedure as in Example 1 was carried out except that weaving a twill weave having a weaving density of 100 warp / inch (2.54 cm) and 71 wefts / inch (2.54 cm) using only yarn 1. ..
本発明によれば、難燃性だけでなく、火炎または熱によって暴露された際に優れた強度を有する布帛および繊維製品が得られその工業的価値は極めて大である。 According to the present invention, not only flame retardant but also fabrics and textile products having excellent strength when exposed by flame or heat can be obtained, and their industrial value is extremely great.
