に、糸条表面に嵩高性を付与することによりゴムや樹脂
との接着力を向上させる方法が提案されている。Since polyester fibers have various excellent properties, they are widely used not only for clothing but also for general industrial materials. In industrial material applications, after weaving, there are many cases where rubber or resin is adhered and used as a composite, for example, as seen in JP-A-63-12730, bulkiness is applied to the yarn surface. There has been proposed a method of improving the adhesive force with rubber or resin by applying the composition.

On the other hand, if weaving is carried out at a high temperature after weaving to a low density, there is an obstacle that the adhesive strength is reduced due to the decrease in bulkiness and the strength is also reduced.

Examples include, but are not limited to, difunctional carboxylic acids such as isophthalic acid, naphthalenedicarboxylic acid, and adipic acid, and diol components such as neopentyl glycol, diethylene glycol, and propylene glycol. If the copolymerization amount of the third component is less than 8 mol, the desired shrinkage ratio cannot be obtained. On the other hand, if it exceeds 30 mol%, fusion of chips during solid-phase polymerization performed by a known method or Poor biting of chips at the time of melting and discharging is likely to occur.

が得られない。Yarn A constituting latent bulky composite yarn used in the present invention
Has a dry heat shrinkage at 80 ° C of 20% or more, and if it is less than 20%, the difference in shrinkage from yarn B is small, and even when subjected to a relaxation treatment at a low temperature, the bulkiness is low and high adhesiveness is exhibited. do not do. However, if it is too high, a flat woven fabric cannot be obtained after weaving and relaxation treatment.
糸条Ａの80℃の乾熱収縮率の好ましい範囲は、25〜30
％である。The preferable range of the dry heat shrinkage at 80 ° C. of the yarn A is 25 to 30.
%.
また、もう一方の糸条Ｂは、糸条Ａに対して、80℃の

る。The other yarn B has a difference in dry heat shrinkage at 80 ° C. from yarn A of 10% ≦ (dry heat shrinkage of yarn A−dry heat shrinkage of yarn B). ≦ 20. If the difference between the dry heat shrinkage ratios of the yarn A and the yarn B is less than 10%, the bulkiness is reduced and high adhesiveness is not exhibited, while if it exceeds 20%, the proportion of the yarn B is excessive. When a composite is obtained by attaching a resin to the obtained woven fabric, the resin does not flow in, and bubbles are easily generated, so that the adhesive strength is reduced.
さらに、本発明の製造方法において、糸条Ｂは、その
該複合糸全体に占める割合が10〜60重量％である。糸条
Ｂの割合が10重量％未満では、低温弛緩処理しても嵩高

い。Furthermore, in the production method of the present invention, the ratio of the yarn B to the entire composite yarn is 10 to 60% by weight. When the proportion of the yarn B is less than 10% by weight, the bulkiness is low even at low-temperature relaxation treatment, and high adhesive strength is not exhibited. Cloth cannot be obtained.
本発明で使用する潜在嵩高複合糸は、５〜100ケ/mの
範囲の交絡部を有する。適度に糸条Ａと糸条Ｂを交絡さ
せることで、糸条Ｂの遊離を防ぐとともに糸条Ａと糸条
Ｂとを交絡させることにより、弛緩処理後の糸条内部に
空隙が生じる。The latent bulky composite yarn used in the present invention has an entangled portion in the range of 5 to 100 / m. By appropriately entanglement of the yarn A and the yarn B, the release of the yarn B is prevented, and the entanglement of the yarn A and the yarn B creates a void inside the yarn after the relaxation treatment.
この空隙は、樹脂加工時の樹脂を糸条Ａ内部にも極力
多く浸透させる役目を果たす。糸条Ａが絞り込み状態に
ある場合、殆ど空隙がないと糸条Ａの内部への樹脂浸透
は難しく糸条Ａの外層部のみの樹脂付着となり接着性が
低下する。交絡部が５ケ/m未満では、糸条Ａと糸条Ｂの
交絡部は殆どないに等しく、糸条Ｂの分離が起こる。一
方、交絡部が100ケ/mを超えると、糸条Ａと糸条Ｂの区
別がつきにくく、そのため糸条Ａの直線状繊維が少なく
なり、逆に曲線状の繊維が増加し１％伸長時の応力が低
下する傾向にある。この交絡数は好ましくは20〜60ケ/m
である。These voids serve to allow the resin during resin processing to penetrate as much as possible into the interior of the yarn A. When the yarn A is in the narrowed state, if there is almost no void, it is difficult to penetrate the resin into the inside of the yarn A, and the resin adheres only to the outer layer portion of the yarn A, and the adhesiveness is reduced. If the entangled portion is less than 5 / m, the entangled portion between the yarn A and the yarn B is almost nil, and the yarn B is separated. On the other hand, if the entangled portion exceeds 100 / m, it is difficult to distinguish between the yarn A and the yarn B, so that the number of linear fibers of the yarn A decreases, and conversely, the number of curved fibers increases and the elongation increases by 1%. The stress at the time tends to decrease. This confounding number is preferably 20 to 60 pcs / m
It is.
また、本発明で使用する潜在嵩高複合糸は、最大引張
荷重時の強度が6g/d以上、好ましくは6.2〜6.7g/dであ
る。The latent bulky composite yarn used in the present invention has a maximum tensile load strength of 6 g / d or more, preferably 6.2 to 6.7 g / d.
最大引張荷重時の強度が6g/d未満では、屋外テントや
エアバッグなどの産業資材として使用する場合、耐疲労
性が低く実用上の問題がある。When the strength at the maximum tensile load is less than 6 g / d, when used as an industrial material such as an outdoor tent or an airbag, the fatigue resistance is low and there is a practical problem.
本発明で用いる潜在嵩高複合糸は、例えば第１図に示

In the peripheral speed difference between the second feeding roller 9 and the second feeding roller 9, the pre-stretching state is adjusted to a constant length or about 1.003 to 1.005, and they are simultaneously supplied. Here, yarn A (raw yarn 1)
Has potentially high shrinkage at low temperatures, and
The point of the present invention is that the composite yarn obtained by simultaneously supplying (the original yarn 1) and the yarn B (the original yarn 2) is a fiber which does not potentially exhibit bulkiness.

This is used for warp and weft and woven to form a plain fabric (taffeta), and then subjected to a relaxation treatment at a low temperature of 80 ° C or lower, whereby the bulky high-density woven fabric for industrial materials of the present invention is obtained.
