Description

【発明の詳細な説明】 本発明は可撓性膜材料及びその製造方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flexible membrane material and a method for manufacturing the same.

ゴム引布のように織物の上に弾性体１を被覆し
た複合膜材料（第１図参照）からなる製品におい
て、その膜材料の引裂強さは膜材料の強度上最も
重要な問題である。即ち膜張力に対応する引張強
さを確保したとしても引裂強さが引張強さの割に
弱くおうおうにして引裂き破壊がおこりやすい状
況にあつた。またこのような膜材料には一般に重
量を可能な限り軽減したい要求も大きい。 In a product made of a composite membrane material (see FIG. 1) in which an elastic body 1 is coated on a fabric such as a rubberized cloth, the tear strength of the membrane material is the most important issue in terms of the strength of the membrane material. That is, even if a tensile strength corresponding to the membrane tension was secured, the tear strength was weak compared to the tensile strength, and tear failure was likely to occur. Furthermore, there is generally a strong demand for reducing the weight of such membrane materials as much as possible.

ところでこのような膜材料において引裂強さを
上げようとすれば、織物の糸を太くし、かつ糸と
糸との隙間を広げて糸の動く自由度を大きくして
やればよい（第２図参照）。このようにすれば引
裂かれる際の荷重を分担する繊維が多くなるため
である。 By the way, if you want to increase the tear strength of such membrane materials, you can make the threads of the fabric thicker and widen the gaps between the threads to increase the freedom of movement of the threads (see Figure 2). . This is because more fibers will share the load when torn.

い。 However, in the conventional processing methods for covering the elastic material, such as calendar processing and spread processing (covering the elastic material by squeezing it with a knife after making it into a paste with a solvent), the elastic material is formed in the concave areas between the threads. It becomes bulkier and the weight increases. Furthermore, since the elastic body fills the space between the threads, the degree of freedom of the threads is reduced, and the effect of opening is also reduced. On the other hand, if the yarn is untwisted and the cross section of the yarn is made flat, the weight and thickness will be reduced, but when looking at the cross section of the yarn, many of the filaments on the surface are restrained by the permeated elastic material, and the overall thickness of the yarn is not utilized. Tear strength does not increase (see Figure 3). That is, (1) in the conventional product shown in Figure 1, the elastic body in which thin threads are tightly packed fills the space between the threads, so the degree of freedom of the threads is small and the threads share the tearing load. The number of books is small. Therefore, tear strength is low.

間に弾性体が埋まり重量大きくなる。(2) However, even if a conventional fabric with thick threads and a low thread density is used to increase tear strength, as shown in the conventional product shown in Figure 2, the conventional processing method does not allow an elastic material to be formed between the threads. fills up and the weight increases.

らない。(3) On the other hand, when using a fabric with a low thread density of untwisted flat threads like the conventional product shown in Figure 3, the weight is small, but when looking at the cross section of each thread, the elastic material impregnated on the thread surface is Compared to yarn twisted with adhesive (FIG. 4b), many of the filaments themselves are restrained, the thickness of the entire yarn is not utilized, and the tear strength is not increased.

本発明は上記問題点に鑑み、膜材料の重量を小

層された膜材料及びその製造方法に関する発明で
ある。 In view of the above-mentioned problems, the present invention seeks to reduce the weight of the membrane material and increase its tear strength. That is, it consists of a flexible sheet or film, a perforated fabric using twisted threads, and a solvent-free or solvent-soluble elastic material that can be sprayed, and the sheet or film and the elastic material are covered. The present invention relates to a membrane material in which the above-described fabrics are laminated, and a method for manufacturing the same.

その製造方法は例えばまず可撓性のシートある
いはフイルムの上に目あき織物をおき弾性体を吹

うなもので可撓性シートあるいはフイルム１枚と
織物１枚からなる。第４図中１は弾性体、２は織
物の糸、３は可撓性シートあるいはフイルムであ
る。 The manufacturing method is, for example, first placing a perforated fabric on a flexible sheet or film and spraying an elastic material on it to integrate it. Of course, the flexible sheet or film may be treated with an adhesive in advance, or a thin layer of elastic material may be spray-coated before the fabric is placed on it. The simplest membrane material produced in this manner is shown in FIG. 4 and consists of one flexible sheet or film and one woven fabric. In FIG. 4, 1 is an elastic body, 2 is a fabric thread, and 3 is a flexible sheet or film.

又第５図は織物の目あきを説明する図であつて
糸２と糸２との間隙ｌを有するものでｌが少くと
も0.3mm以上のものを目あき織物という。 Fig. 5 is a diagram for explaining the opening of a woven fabric, and a woven fabric having a gap 1 between the threads 2, where 1 is at least 0.3 mm or more, is called an open woven fabric.

これらによつて製造された膜材料は高引裂強さ
と軽量化の特徴をもつ。上記を具体的に説明す
る。 Membrane materials produced using these materials are characterized by high tear strength and light weight. The above will be explained specifically.

減が可能である。この場合糸と糸の間を埋める弾
性体がないため、同じ目あき織物を使つても従来
の加工方法による膜材料より糸の自由度大きく引
裂強さにとつても有利である。 The textile has a perforated structure made of twisted threads. As mentioned earlier, the perforated fabric has a large degree of freedom in the threads and has high tear strength. In addition, since the elastic material is applied by spraying, by adjusting the properties such as the viscosity and solid content of the elastic material or elastic material solution and considering the drying conditions, it is possible to coat the fabric with a substantially uniform thickness regardless of the unevenness of the fabric. In other words, instead of having a uniform thickness as a whole of the membrane material as in conventional processing methods, the thickness of the covering elastic body is rather uniform.
The number of elastic bodies occupying unnecessary concave portions of the fabric is reduced, and weight can be reduced. In this case, since there is no elastic material to fill in the spaces between the threads, the threads have greater freedom of movement than membrane materials produced by conventional processing methods, and are also advantageous in terms of tear strength, even if the same perforated fabric is used.

一方撚つた糸を用いたことの意味は前述のよう
に無撚りのものは偏平化し糸断面でみた場合表面
のフイラメントの拘束範囲が増え糸全体の太さの
荷重分担効果が減少するのでこれをさけるためで
ある（第３，４図参照）。 On the other hand, the meaning of using twisted yarn is that, as mentioned above, untwisted yarn becomes flattened, and when viewed from the yarn cross section, the restraint range of the filaments on the surface increases, and the load sharing effect of the overall yarn thickness decreases. This is to avoid this (see Figures 3 and 4).

第４図はこのような膜材料の最も単純なもので
あるが、たとえば可撓性シートフイルムの反対側
にもう一層弾性体を吹き付け塗布した織物或いは
弾性体単独の層を設けてもよい。また可撓性シー
トフイルムと弾性体を吹き付け塗布した織物を交
互に積層していつてもよい。 Although FIG. 4 shows the simplest of such membrane materials, for example, on the opposite side of the flexible sheet film, a fabric coated with another layer of elastic material or a layer of the elastic material alone may be provided. Alternatively, flexible sheet films and woven fabrics coated with an elastic material may be alternately laminated.

このようにしてつくられた膜材料は可撓性のシ
ートフイルムの材質を選ぶことにより多岐の用途

フイルムを最外層としてやればより軽量な膜構造
物のテントなどに使えるし気体、液体の透過を防
ぐバリヤ材をもつてくれば容器にも使える。 The membrane material made in this way can be used for a variety of purposes depending on the material of the flexible sheet film. For example, if a flexible sheet film with excellent weather resistance is used as the outermost layer, it can be used for lightweight membrane structures such as tents, and if a barrier material is added to prevent the permeation of gases and liquids, it can be used for containers.

強さを有せしめることが出来る。 The present invention as described above has the following advantages. In other words, the membrane material is (1) a perforated fabric made of twisted threads, and the elastic material does not completely fill the spaces between the threads, which increases the freedom of the threads and allows the overall thickness of the threads to be maximized. The number of threads that share the tearing load, that is, the thickness of the threads, can be increased. Therefore, it can have high tear strength.

(2) 目あきの織物にもかかわらず従来の加工方法

覆厚さが織物の凹凸にかかわらず均一化する方
向にある。従つて軽量である。(2) Even though the fabric is open, the elastic body is coated by spray coating without using conventional processing methods, so the thickness of the entire membrane material is not uniform, but the coating thickness is independent of the unevenness of the fabric. The trend is toward uniformity. Therefore, it is lightweight.

容易で工程の減少が計れる。 In addition, the manufacturing method is as follows: (1) A perforated fabric is simply placed on a flexible sheet film and the elastic material is applied by spraying, so there is no need to cover the fabric with an elastic material using a large-sized device.
Further, equipment such as a laminator is not required when laminating such an elastic material-covered fabric and a flexible sheet film. Since the elastic coating is applied by spraying, it can be easily worked in any location (on-site). In addition, local parts of large-area membrane structures,
Repairs can also be done easily. That is, manufacturing is easy and the number of steps can be reduced.
