難いという問題点があった。2. Description of the Related Art Conventionally, a rubberized cloth provided with a natural rubber or a synthetic rubber sheet on the surface of a fiber cloth has excellent airtightness and flexibility, and thus has been widely used as a material for clothing, sundries, air goods and the like. Has been. This rubberized cloth is usually a base cloth impregnated with an isocyanate compound or a resorcin-formaldehyde resin, and then coated with a rubber adhesive on one or both surfaces thereof to adhere a natural rubber or a synthetic rubber sheet, followed by a vulcanization treatment. It is obtained by doing. It is also known that, depending on the application, one or both sides of the base cloth are coated with a rubber adhesive and then vulcanized to provide a rubber coating layer on one or both sides of the base cloth. For applications such as life preservers, boats, balloons, and rafts that require high airtightness, a rubberized cloth having a rubber sheet on both sides of a base cloth is usually used. However, in the conventional rubberized cloth, the airtightness of the base cloth itself is inferior. Therefore, for example, when an airtight product is made using the rubberized cloth, if the rubber sheet has pinholes, etc. The air leaks from the cross section of the pulling cloth at the pasting part, and the airtightness cannot be maintained, which is an undesirable situation. Therefore, the applicant of the present invention has previously found that a rubberized cloth having excellent airtightness can be manufactured by using the airtight woven cloth as a base cloth for the rubberized cloth, and a method for manufacturing the airtight woven cloth is found. As, as the outer peripheral surface of the roll-shaped woven fabric is covered with a flexible airtight sheet, while rotating the roll-shaped woven fabric while reducing the pressure on one end surface, after a predetermined amount of rubber liquid is pressed from the other end surface, A method for producing an airtight woven fabric is proposed, which is characterized in that pressure reduction and rotation are maintained until the squeezing effect is sufficiently exerted, and then the roll-shaped woven fabric is taken out and dried (Patent Application No. 3). -55916). However, this method has a problem that it is difficult to apply it to an efficient continuous manufacturing method.

絶対圧力０.５kg／cm2以下の範囲が好ましい。The pressure of the liquid containing the rubber in which the woven fabric is dipped is not particularly limited, but it is preferable that the reduced pressure easily removes the air in the voids between the fibers. Therefore, it is particularly preferable to remove the air in the voids between the fibers by the depressurizing section and then to fill the voids between the fibers with the rubber in the atmospheric pressure section. The degree of vacuum is usually preferably in the range of absolute pressure of 0.5 kg / cm 2 or less.

る。Various devices can be used as a device for reducing the pressure of a liquid containing rubber for continuously dipping a woven cloth, but the principle of Tricherry as shown in FIG. 1 is used. Preferred devices. The device using the Trichery principle has at least two liquid surfaces of the rubber liquid contained in the device, and the gas phase portion above one liquid surface of the rubber liquid is decompressed. The liquid level is higher than the liquid level of the rubber liquid where the woven fabric is continuously supplied. The height difference between these liquid levels depends on the degree of pressure reduction in the gas phase above the liquid level and the specific gravity of the rubber liquid, but a rubber liquid with a large specific gravity is used to reduce the height difference and the rubber dipping device. Preferably. By such an operation, the rubber liquid is sufficiently filled in the voids between the fibers of the woven cloth.

用途に用いることができる。After the filling of the rubber liquid is completed in this manner, the desired airtight woven fabric can be obtained by taking out the woven fabric from the liquid containing rubber and drying it. At this time, the drying may be room temperature drying or heat drying, but when a rubber liquid containing a vulcanizing agent or a vulcanization accelerator is used, it is further heated and vulcanized after drying. Processing is performed. The airtight woven fabric thus obtained is extremely excellent in airtightness because the rubber layer is densely present in the voids between the fibers, and for example, this airtight woven fabric is used as the base fabric. When a rubber-lined cloth is produced and an airtight product is manufactured, even if there are pinholes in the rubber sheet, there is almost no air leakage from the cross section of the rubber-lined cloth at the bonding section, Airtightness can be maintained for a long time without tape sealing. By observing the cross section of the airtight woven fabric obtained by the method of the present invention with an electron micrograph, it can be seen that the rubber layer is densely present in the voids between the fibers.
Since the airtight woven fabric obtained by the method of the present invention is extremely excellent in airtightness, it can be used as it is as a raw material for applications requiring airtightness, and the woven fabric is used as a base fabric. Create rubberized fabrics, such as boats, life preservers,
It can be used for applications requiring strict airtightness such as air objects such as balloons and rafts.

はへの浸漬時間は、１〜５分であった。Example 1 FIG. 1 shows a schematic side sectional view of an example of an apparatus used in the manufacturing method of the present invention. FIG. 2 also shows a cross-sectional schematic view of the back side of the device of FIG. The rubber liquid immersion device 1 contains a liquid 4 containing rubber (a methylene chloride solution having a chloroprene rubber concentration of 14% by weight and a viscosity at 25 ° C. of 200 to 300 cps), and a gas phase above the liquid surface 6. The part is connected to the decompression tank 12 and the absolute pressure is 0.3k.
The pressure is reduced to g / cm 2 . As a result, the liquid level 6 is higher than the liquid level 5, and in the liquid 4 containing rubber, the degree of decompression increases as it approaches the liquid level 6, and as the depth from the liquid level 6 increases, the liquid 4 Due to its own weight, the pressure is high. A rubber liquid preliminary tank 13 containing the rubber liquid 4 is connected to the rubber liquid dipping device 1, and the amount of the rubber liquid 4 can be freely adjusted according to the degree of pressure reduction. The depressurization has a function of keeping the liquid surfaces 5 and 6 constant and a function of letting air released from inside the woven fabric 2 escape to the outside. In addition, the air released from the woven fabric becomes bubbles, and when it goes out through the pressure reducing holes, the loss of the rubber liquid becomes large, so that it works to prevent this. On the other hand, the liquid surface 5 is at atmospheric pressure, and the raw fabric roll 3 of the continuous plain-woven fabric 2 having a width of 1.4 m and a thickness of 0.25 mm, which is made of nylon fiber (fineness: 420 denier, 50 filaments / woven yarn) 3 Therefore, the woven fabric 2 is continuously supplied from the liquid surface 5 into the rubber liquid 4. In the rubber liquid 4, the woven fabric 2 is first wound around the roll 7 and the roll 8, and then wound around the roll 9 and guided to the vicinity of the liquid surface 6 having a large degree of reduced pressure. Since the degree of pressure reduction increases as it approaches the liquid surface 6, it becomes easier to remove the air contained in the voids between the fibers of the woven fabric 2. In FIG. 1, the roll near the liquid level 6 is one roll 9, but two or more rolls are arranged near the liquid level 6 to keep the woven fabric 2 in a lower depressurized state for a long time. Is also preferable. Then, the woven fabric 2 is wound around the rolls 10 and 11 and guided to the deep portion of the rubber liquid 4. The deeper the depth from the liquid surface 6 is, the larger the pressure difference becomes, and the rubber liquid 4 is formed between the fibers of the woven cloth 2 between the fibers.
Are easily impregnated. The pressure between rolls 10 and 11 is the highest, and the absolute pressure is 1.1 to 1.2 kg /
It is cm 2 . In addition, these rolls 7-11 are
The woven cloth 2 is smoothly rotated by rotating. The woven fabric 2 wound around these rolls and pulled was pulled at a take-up speed of 5 to 20 m / min, and the tension applied at that time was 0.5 to 2 kg / cm. It is preferable to apply a tension of this degree to the woven fabric 2 because it facilitates the impregnation of the rubber liquid into the voids between the fibers. Also, the rubber liquid 4 of the woven fabric 2
The soaking time was 1 to 5 minutes.

When the cross section of the airtight woven fabric thus obtained was observed with an electron micrograph, it was confirmed that the rubber layer was densely present in the voids between the fibers. Next, in order to investigate the airtightness of the airtight woven fabric, a chloroprene rubber sheet and a chloroprene rubber-based adhesive were used, and a rubberized fabric having chloroprene rubber sheets on both sides of the woven fabric was prepared according to a usual method. ,
Airtightness was determined by a pressure resistance method and a pillowback method. As a result, no pressure leakage was observed at 2 kgf / cm 2 by the pressure resistance method, and no cross-section leakage was confirmed by the pillowback method.
