【考案の詳細な説明】
本考案はカメラ、鞄等の吊り下げ紐、衣服用ベルト等に
使用される合成樹脂製帯状体に関するものである。[Detailed Description of the Invention] The present invention relates to a synthetic resin belt-like body used for hanging straps for cameras, bags, etc., clothing belts, etc.
従来、この種の合成樹脂製帯状体として、補強用ガラス
繊維が埋設された塩化ビニル樹脂製帯状体が知られてい
る。Conventionally, as this type of synthetic resin strip, a vinyl chloride resin strip in which reinforcing glass fibers are embedded is known.
しかしながら、かかる塩化ビニル樹脂製帯状体は耐寒性
が必ずしも十分とはいえなく、０〜５℃で硬直し折り曲
げると亀裂、破れ等が生じやすい欠点がある。However, such vinyl chloride resin strips do not necessarily have sufficient cold resistance, and have the disadvantage that they become stiff at 0 to 5° C. and tend to crack or tear when bent.
本考案者はかかる従来の欠点に鑑み鋭意工夫の結果、上
述の欠点を解消した合成樹脂製帯状体を提供するもので
ある。In view of these conventional drawbacks, the inventor of the present invention has made extensive efforts to provide a synthetic resin belt-like body which eliminates the above-mentioned drawbacks.
以下、図面を参照しながら本考案の一実施例について説
明する。An embodiment of the present invention will be described below with reference to the drawings.
図面に於て、１は芯材であって、後述の塩化ビニル樹脂
層２によりその外表面が被覆されるのであって、少くと
も塩化ビニル樹脂層２の押出成形時の熱で強度低下をき
たさないものがよく、例えばガラス繊維、テレフタール
酸系ポリエステル繊維、木綿、麻等から作製されている
。In the drawings, reference numeral 1 denotes a core material, the outer surface of which is covered with a vinyl chloride resin layer 2, which will be described later. For example, it is made from glass fiber, terephthalic acid polyester fiber, cotton, linen, etc.
又、該芯材１は単に上述の繊維が多数並列されるか、あ
るいは織成された帯状となされていてもよいが、あらか
じめ接着剤や樹脂の溶液、エマルジョン、プラスチゾル
等を含浸させておけば塩化ビニル樹脂層２との結合が強
固となり好ましい。Further, the core material 1 may be formed into a belt shape in which a large number of the above-mentioned fibers are simply arranged in parallel or woven, but if it is impregnated with an adhesive or resin solution, emulsion, plastisol, etc. in advance. This is preferable because the bond with the vinyl chloride resin layer 2 is strong.
塩化ビニル樹脂層２は重合度２０００〜２５００の塩化
ビニル樹脂（可塑剤、安定剤を含む）が押出成形されて
芯材１の外表面を被覆する如く形成されたものである。The vinyl chloride resin layer 2 is formed by extrusion molding a vinyl chloride resin (including a plasticizer and a stabilizer) having a degree of polymerization of 2000 to 2500 to cover the outer surface of the core material 1 .
該塩化ビニル樹脂層２は特に耐寒性を高めるために重合
度２０００〜２５００の塩化ビニル樹脂により形成され
、該樹脂層２の厚さは通常０゜５〜１ｍｍとなされてい
る。The vinyl chloride resin layer 2 is formed of a vinyl chloride resin having a degree of polymerization of 2000 to 2500 in order to particularly improve cold resistance, and the thickness of the resin layer 2 is usually 0.5 to 1 mm.
３は熱可塑性ウレタン樹脂層であって、塩化ビニル樹脂
層２の外表面を被覆する如く形成されたものである。A thermoplastic urethane resin layer 3 is formed to cover the outer surface of the vinyl chloride resin layer 2.
該樹脂層３の厚さはあまり厚すぎるとゴム弾性が生じ従
来の天然皮革製帯状体と異なり、あまり薄すぎると塩化
ビニル樹脂層２に含まれる可塑剤が表面に移行するので
、通常０．１〜０．５ｍｍとなされている。If the thickness of the resin layer 3 is too thick, rubber elasticity will occur, unlike conventional natural leather strips, and if the resin layer 3 is too thin, the plasticizer contained in the vinyl chloride resin layer 2 will migrate to the surface, so it is usually 0. It is set at 1 to 0.5 mm.

芯材の外表面に重合度１０００の塩化ビニルを被覆した
本考案と同寸法の従来の帯状体との耐寒性（硬度）をＪ
ＩＳ硬度計により測定しその結果を第１表に示した。For example, now ECG 150 + -3 as core material
, 30 glass fiber threads of 8S were aligned in the longitudinal direction, treated with plastisol, turned into a gel, and the outer surface was coated with a polymerization degree of 2000.
The belt-shaped body of the present invention is coated with vinyl chloride having a polymerization degree of 1000, and the outer surface of the belt-shaped body is coated with thermoplastic urethane. The cold resistance (hardness) of the conventional strip material is J
The hardness was measured using an IS hardness meter and the results are shown in Table 1.
すなわち、第１表よりわかるように、本考案の帯状体は
温度が下っても硬度がほとんど変らず、耐寒性が良好で
あって、折り曲げても従来の如く簡単に亀裂が生じるこ
とがない。That is, as can be seen from Table 1, the hardness of the strip of the present invention hardly changes even when the temperature drops, and it has good cold resistance, and does not easily crack when folded, unlike conventional strips.
以上詳述した如く、本考案の合成樹脂製帯状体は芯材の

を向上させることができると共に、柔軟性、感触、外観
等天然皮革とほぼ同等の帯状体とすることができる。As detailed above, in the synthetic resin strip of the present invention, the outer surface of the core material is coated with a vinyl chloride resin layer with a degree of polymerization of 2000 to 2500, and the outer surface of the resin layer is further coated with a thermoplastic urethane resin layer. As a result, it is possible to improve the cold resistance compared to conventional products, and it is also possible to make a belt-shaped product that has almost the same flexibility, feel, appearance, etc. as natural leather.
又、耐摩耗性に於ても従来の帯状体よりも優れた帯状体
とすることができる。Furthermore, it is possible to obtain a belt-shaped body that has better wear resistance than conventional belt-shaped bodies.
