また、スパン糸を材料とする基布においても、その構
成する繊維、糸番手、織り組織、密度等によって差があ
り、特に構成繊維の種類は、ヤング率、弾性率、振動等
に関する因子を支配するため、その音響効果に多大の影
響を与える。In the case of spun yarn base fabric, there are also differences depending on the constituent fibers, yarn count, weave structure, density, etc., and the type of constituent fibers in particular governs factors related to Young's modulus, elastic modulus, vibration, etc. Therefore, the sound effect is greatly affected.
アクリル繊維は、このダンパー用としては比較的良好

った。Acrylic fiber has relatively good performance for this damper, but lacks heat resistance. For this reason, it is impregnated with a thermosetting resin (usually a phenol resin is used) and hardens significantly during molding. In addition, since shrinkage occurs due to the heat of molding, it is necessary to perform molding at a low temperature for a long time, and the production efficiency is extremely poor, and it has been difficult to commercialize the product.
本発明は下記のとおりである。 The present invention is as described below.
アクリロニトリルの含有量が93重量％以上の重合体を
紡糸して得られたアクリル繊維を使用して紡績、製織し
た後、熱処理することにより、耐熱性及び熱寸法安定性
を付与したスピーカーダンパー用基布。An acrylic fiber obtained by spinning a polymer having an acrylonitrile content of 93% by weight or more is spun and woven, and then heat-treated to provide heat resistance and thermal dimensional stability for a speaker damper base. cloth.
本発明のダンパー用基布は、アクリロニトリルの含有

硬化性樹脂初期縮合物に含浸後、例えば、熱処理温度20
0〜260℃、180秒の処理においても優れた耐熱性を示
す。また、一般のアクリル繊維では不可能であった乾熱
160〜240℃の熱処理（ヒート・セット）により、寸法安
定性が極めて優れているため、高温熱処理においても収
縮が極めて少なく、生産上有利であり、また、音に歪み
を生ずることのない基布を提供することができる。The base fabric for a damper of the present invention has an acrylonitrile content of 93% by weight or more, and thus has improved heat resistance.
It shows excellent heat resistance even when treated at 0 to 260 ° C for 180 seconds. Also, dry heat that was impossible with ordinary acrylic fiber
Base fabric that is extremely excellent in dimensional stability due to heat treatment at 160-240 ° C (heat set), has very little shrinkage even at high temperature heat treatment, is advantageous in production, and has no sound distortion. Can be provided.

紡糸、水洗、延伸、弛緩することによって、各1.5デニ
ールのアクリル繊維を得た。The four types of polymer solutions obtained by polymerizing the compositions shown in Table 1 below in a concentrated solution of zinc chloride were spun, washed with water, stretched, and relaxed in a coagulation bath to obtain 1.5-denier acrylic fibers. Was.
得られた４種類のアクリル繊維を、それぞれ短綿紡方
式にて、綿番手20/1の糸を紡績し、次の織物規格にて、
製織した。 The resulting four types of acrylic fiber are spun into yarns of cotton count 20/1 by the short cotton spinning method, and according to the following textile standards,
Weaved.

した。Of these fabrics, fabrics of B, C, and D excluding A are 220
Heat setting was performed at 45 ° C. for 45 seconds using a hot tenter to give dimensional stability to prepare a base fabric for a speaker damper. (A was not carried out because curing occurred at 220 ° C.) Comparative Example On the other hand, for comparison with the thus obtained base cloth, the most standard cotton damper base cloth currently used at present was used. Woven fabric: 38 inches wide x 103 m long Texture: Plain texture is simultaneously impregnated with a phenolic resin prepolymerized product, 230 ° C
And press molded at a pressure of 350 kg / cm 2 for 6 seconds.
本発明のダンパー用基布と比較例の木綿基布につい
て、それぞれ収縮率を測定した結果は第２表の通りであ
