ーブが得られることを見出した。Problems to be Solved by the Invention The present inventor coated a cylindrical seamless woven fabric obtained by hollow weaving with an elastomer to make a woven fabric reinforced elastomer tube, and then butted and joined both open ends of this tube. Or, research was being conducted on manufacturing bicycle tire tubes by overlapping and bonding, but using polyurethane elastomer as the elastomer would be much lighter than conventional butyl rubber or natural rubber tire tubes.

るものである。That is, the gist of another invention of the present application is "a method for manufacturing a circular woven fabric characterized by weaving warps arranged in a general pattern with weft yarns in the width direction over the entire circumference." It is.
以下本発明の詳細な説明する。The present invention will be explained in detail below.

本発明の円環状織布を製造するにあたっては、経糸を第
１図のように総状に配置する。つまり、１本の経糸をル
ープを描きながら順にそうこう通しおよびおさ通しを行
う。In manufacturing the annular woven fabric of the present invention, the warp threads are arranged in a general shape as shown in FIG. In other words, one warp thread is threaded and threaded in order while drawing a loop.
ついで常法に従い、第２図のように、そうこうによる経
糸の開口運動、シャトルによる緯入運動、緯糸をおさに
より織目へ打ち寄せる緯打運動を行う。Next, according to the usual method, as shown in Fig. 2, the shedding movement of the warp threads by the sheath, the weft insertion movement by the shuttle, and the weft beating movement in which the weft threads are brought against the weave by the reed are carried out.
この場合、製織は袋織りにより行う。袋織りとは、二重
織りの一種であって、奇数の経糸を配列して２枚重なっ
た織物を織る方法である。この方法に従って製織を行え
ば、緯糸が２往復することによって一つの環状を形成し
、結局緯糸はらせん状に進んで順次筒形を形成し、両級
で表裏が接結された筒型の製織構造物が得られることに
なる。In this case, the weaving is done by bag weaving. Bag weave is a type of double weave, and is a method of weaving two overlapping fabrics by arranging an odd number of warp threads. If weaving is carried out according to this method, the weft threads will move back and forth twice to form a ring shape, and eventually the weft threads will proceed in a spiral pattern to form a cylindrical shape one after another, resulting in a cylindrical weaving with the front and back sides tied together in both grades. A structure will be obtained.
織り進みに応じ、形成された織布を引き取りながら、そ
の分だけ総状の経糸を送り出していく。As the weaving progresses, the woven fabric that has been formed is taken up and the warp threads are fed out accordingly.
織り進みが総状の経糸の１周近くになると、そうこうに
よる開口運動が行いにくくなるので、この時点で機械織
りを中止して手織りに移行する。When the progress of weaving approaches one round of the warp threads, it becomes difficult to perform the shedding motion by the weaving, so at this point machine weaving is stopped and hand weaving is started.
さらに織り進みと、手織りも不可能になるので、シャト
ルの使用を中止して針を用いて手縫いにより残りの部分
の製織を行う。As the weaving progresses further, hand weaving becomes impossible, so the use of the shuttle is stopped and the remaining portion is woven by hand using a needle.
以上の操作により、目的とする円環状織布が扁平形状で
得られる。この織布には継ぎ目がないことになる。扁平
形状の円環状織布を膨張させれば、円環状となる。Through the above operations, the desired annular woven fabric is obtained in a flat shape. This woven fabric will have no seams. When a flat circular woven fabric is expanded, it becomes circular.

も緯糸も非伸縮性または伸縮率の小さい糸を用いること
ができる。When expanding a flat circular woven fabric, an expansion force is applied in the radial direction of the tube, so it is desirable to use stretchable yarn as the weft for purposes of expanding the fabric. On the other hand, from the viewpoint of weavability, it is desirable to use non-stretchable or low-stretch threads for the warp. However, when performing bellows processing as described below, the difference between the inner and outer circumferences of the ring can be absorbed by the widening of the bellows, so it is recommended to use non-stretchable yarns or threads with a small expansion/contraction rate for both the warp and weft. can.

ことによっても達成できる。The bellows can be formed, for example, by weaving threads with a large heat shrinkage rate as wefts at regular intervals to obtain a circular woven fabric, or after producing a circular woven fabric and further providing a resin coating layer.
This can be achieved by shrinking the weft yarns having a high heat shrinkage rate by performing wet heat or dry heat treatment. It can also be achieved by pleating the annular woven fabric or its resin coating by mechanical means.

中に浸漬してから引き上げ、乾燥した。This flat circular woven fabric is immersed in a solvent solution of an adipate ester polyurethane elastomer with a specific gravity of 1.22, then pulled up, a needle is inserted and air is blown through it to make it expand, and the fabric is dried once expanded. Then, it was immersed again in the same solvent solution of polyurethane elastomer, then pulled out and dried.

一部は織布の目を通して内面側にも侵入するため、円環
状織布の内面にも被覆層が形成されていた。As a result, a polyurethane elastomer coating layer was formed on the outer surface of the annular woven fabric. Since a portion of the polyurethane elastomer penetrated into the inner surface of the woven fabric, a coating layer was also formed on the inner surface of the annular woven fabric.

A tire tube with a circumference of 1970+am was obtained.

全体が均質である。また、織布であるので、柔軟で、強
度が大きく、かつ極めて軽量である。この円環状織布に
樹脂被覆やベローズ加工を行うことも可能である。The obtained tire tube was attached to a bicycle tire and a running test was conducted to examine its airtightness, wear resistance, and puncture resistance, but no problems were found in practical use. Effects of the Invention Circle of the Invention Circular woven fabric has no seams or joints,
The whole is homogeneous. Furthermore, since it is a woven fabric, it is flexible, strong, and extremely lightweight. It is also possible to perform resin coating or bellows processing on this annular woven fabric.
従って、本発明の円環状織布は、タイヤ用チューブをは
じめ種々の用途に有用である。Therefore, the annular woven fabric of the present invention is useful for various uses including tire tubes.
