本考案は、実質的に高周波縫製が下可能又は困
難な防水布帛に対し高周波縫製を可能ならしめた
防水布帛に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a waterproof fabric that is capable of high-frequency sewing on waterproof fabrics that are practically impossible or difficult to perform high-frequency sewing on.

Conventionally, most of the waterproof fabrics used for truck tops or various covers have been made by coating, pasting, or impregnating vinyl chloride resin on one or both sides of fabrics made of synthetic fibers, etc. Since such a polar material coating such as vinyl chloride resin is easily melted by high frequency, this property can be used to perform high frequency welder bonding processing, and has the advantage that sewing can be easily performed.

防水布帛の高周波縫製を可能ならしめるため種々
の検討の結果到達したものである。 However, recently there has been a demand for lighter weight waterproof fabrics, and for this reason, processing using polyacrylic resin, chlorosulfonated polyethylene, etc. is being carried out instead of using polyvinyl chloride resin processing. Sewing was impossible or difficult. For this reason, for example, Japanese Utility Model Application Publication No. 54-169181 proposes covering the base fabric with a compound with a low dielectric loss rate such as acrylic resin, and then coating the edge of the base fabric with a compound with a low dielectric loss rate such as vinyl chloride resin. It has been proposed to apply a resin with high thermoplasticity so that the resulting waterproof fabric can be melt-bonded at the ears. However, in the waterproof fabric obtained by the above method, the bondability between the thermoplastic resin layer and the composite covering layer having a low dielectric loss factor is low, so even if the edges are melt-bonded, Its adhesive strength was unsatisfactory. This invention solves the above problems,
Furthermore, this invention has been reached as a result of various studies in order to enable high-frequency sewing of waterproof fabrics that have inherent advantages such as light weight and impermeability.

The waterproof fabric of the present invention includes a fiber base fabric, an adhesive layer made of a synthetic resin that is coated, attached, or impregnated on one or both sides of the fabric and has high frequency bonding properties, and the fiber base fabric. The remaining part of one or both sides of the cloth is covered with an impermeable waterproofing agent layer made of natural, synthetic rubber, or synthetic resin that does not have high-frequency bondability or has low bondability. This is a characteristic feature.

となる。 In the waterproof fabric of the present invention, before the waterproofing agent coating is applied to the fiber base fabric, a synthetic resin having high frequency bondability, such as vinyl chloride resin, nylon resin, polyurethane resin, etc. Resin, polyester resin, etc. are applied and pasted and then waterproofed.If this high-frequency bonding area is polymerized and high-frequency sewing is applied to that area, a strong bond of the waterproof fabric can be created. It becomes possible.

成されている。 In FIGS. 1 and 2, the waterproof fabric 1 is
It has a base fabric 1' and a waterproofing agent layer 1'' formed thereon, which is made of natural or synthetic rubber or synthetic resin, such as polyacrylic resin, on which high-frequency sewing is impossible or difficult. The waterproofing agent layer 1'' is of course non-breathable. The important features of this invention are:
An adhesive layer 2 made of a synthetic resin having high-frequency bonding properties is applied or impregnated in advance at the location where one or both sides of the fabric will be sewn before waterproofing. That is, the non-breathable waterproof agent layer 2 is formed in the portion of the base fabric 1' where the adhesive layer 2 is not present.

縫製に時間がかかり作業性が劣り好ましくない。 To perform high frequency sewing, as shown in Figure 2,
The synthetic resin layers 2, 2 are sewn in direct contact with each other, or only one side is sewn in a sandwich-like manner. In particular, high-frequency sewing is particularly effective for heating thick materials such as canvas through the fabric, and ordinary heat fusion is difficult to obtain the desired sewing strength and takes time to sew. It is not preferable because it takes a lot of time and the workability is poor.

ある。 As the high frequency bondable synthetic resin, vinyl chloride resin is most preferred, but nylons such as nylon 11, nylon 12, ethylene vinyl acetate copolymers, polyurethane resins, polyester resins, etc. are also good. Any other material may be used as long as it has polarity and can be melted and bonded using a high-frequency welder. It is also possible to mix other substances within a range that does not inhibit conjugation. In addition, high-frequency bonding of an appropriate thickness may be applied to the fabric by pasting a pre-formed high-frequency bondable synthetic resin tape, or coating and impregnating this resin straight, paste, powder, solution, etc., or by other methods. A sexual film may be formed. These treatments must be carried out before waterproofing the base fabric.

が不可能であつた。 A plain woven fabric made of polyester spun yarn (10/2) woven into 28 pieces x 28 pieces across 2.54 cm is pretreated with adhesive, and polyvinyl chloride resin is pasted on both ends and impregnated with heat melting. Regarding the material impregnated with a waterproofing agent made of acrylic resin, the polyvinyl chloride resin portion was overlapped and high-frequency sewing was performed. Sewing was performed using a high frequency oscillator with an output of 2 kW and a frequency of 40.68 MHz, and electricity was applied for 3 seconds. In this case, the average peel strength of the sewn portion was 9.2 kg/3 cm. As a control example, a waterproof fabric coated entirely with vinyl chloride resin was sewn using high frequency under the same conditions, and the average peeling strength of the sewn portion was 9.3 kg/3 cm.
There was no substantial difference from the waterproof fabric according to the present invention. Furthermore, high-frequency sewing was not possible with products made of acrylic resin.

Next, the raw fabric was immersed in a toluene solution of a resin mixture mainly containing Hypalon to impregnate the front and back surfaces with the resin mixture, squeezed with a mangle, and heat-treated at 140° C. for 4 minutes to obtain a waterproof sheet. The PVC-coated parts of this waterproof sheet were overlapped and high-frequency sewing was performed by applying electricity for 3 seconds using a high-frequency oscillator with an output of 2 kW and a number of cycles of 40.68 MHz. As a result, the average peel strength of the sewn parts was 9.8
It was Kg/3cm. On the other hand, those that are simply processed with Hypalon cannot be sewn using high frequency, and those that are conventionally processed with PVC are 9.2Kg/3.
It was cm.

It only covers the PVC part thinly, so it hardly interferes with the high frequency weld bondability, and moreover, at the boundary between PVC and a resin mixture mainly composed of Hypalon, the two wrap and are formed integrally. As a result, the edges do not become abnormally thick compared to those coated with PVC after being processed with Hypalon, and even when made into a roll, the whole is formed to a uniform height and has an excellent appearance. becomes.

As described above, the waterproof fabric according to the present invention is made by coating, pasting, or impregnating a synthetic resin that can be sewn with high frequency on one or both sides of the waterproof fabric where high-frequency sewing is impossible or difficult. It is possible to perform high-frequency sewing by cutting into a predetermined shape and overlapping the required number of synthetic resin parts, which is different from the conventional method of sandwiching special adhesive tape between the woven fabrics and performing heat fusion or high-frequency sewing. In comparison, the work is significantly simplified, and unlike sewing with a sewing machine, there is no water leakage from the seams, so the troublesome work of overlapping stitches is eliminated, which is extremely advantageous, and its practicality is great. There is.
