Description

  [Technical Field] The present invention relates to a hood cloth for a connected hood, which is characterized by a base cloth of an outer hood, in a hood cloth having a double structure including an outer hood and an inner hood.

The connecting hood installed between railway passenger vehicles is required for the flexible part composed of a rigid part such as a hood frame and a flexible part where the hood cloth is held by the hood bone. Rigidity for maintaining the shape of the connected hood and displacement adaptability that can flexibly adapt to displacements such as up, down, left, right, torsion, and longitudinal direction that occur between running trains. The conformability is ensured by a loose structure in which the hood cloth is held by the hood bone, and the hood cloth that has been widely used in the past has been used to withstand these displacements.

  For example, a hood for connecting hoods used in conventional linking hoods is made by fixing a vinyl chloride-based synthetic resin to a base fabric in which warps and wefts made of nylon filaments are woven. Although there is a one-piece structure, it has been pointed out that this connecting hood for cloth can easily be damaged such as tearing in each part as the above displacement is repeated. If the thickness of the hood cloth is increased in order to solve this problem, the hood cloth becomes heavier and the connected hood hangs down due to its own weight, and the lower part of the connected hood may be damaged by coming into contact with the connecting device below it.

  Conventionally, a tape-like cloth called a kise cloth is fixed to the inner side surface of the hood cloth by sewing and a hood bone insertion hole is provided between the hood cloth and the kise cloth. Alternatively, the hood bone insertion holes are provided by folding back portions in the longitudinal direction of the hood cloth in the longitudinal direction and sewing them with a sewing machine.

  However, this sewing work is not easy to handle due to the wide range of hood cloths, and the length of the sewing machine is long. Therefore, the sewing machine is sewn along the exact position by moving the hood cloth. Requires skilled skills and long working hours with concentration, which puts an overburden on the hood cloth engineer and low production efficiency.

  The applicant has previously developed a double-layered hood for connecting hoods to eliminate such problems, and has already patented this (Patent Document 1, Patent Document 2).

  In the hood for a connected hood described in Patent Document 1 (the hood for a connected hood), the hood is composed of a two-layer structure in which an outer hood and an inner hood are stacked and fixed. The hood is sewn or bonded using an adhesive and joined. A hood bone insertion hole is provided between the outer hood and the inner hood.

The hood cloth for a connected hood described in Patent Document 2 (a sheet composite for a connected hood) is a two-layer hood cloth having an outer hood and an inner hood, and the hood cloth between the outer hood and the inner hood. A lattice-like knitted structure composed of warp-like groups in which reinforcing fibers are arranged in parallel and weft-like groups in which reinforcing fibers are arranged in parallel is arranged, and the outer hood and the inner hood are pressure-bonded by heating and melting. And in this patent document 2, it describes that suitable reinforcement fiber is (high intensity | strength) aramid fibers, such as "Technola (trademark)" by Teijin Ltd.
Japanese Unexamined Patent Publication No. 63-199169 (Japanese Patent Publication No. 6-24931) Japanese Patent Laid-Open No. 6-212532 (Japanese Patent Publication No. 7-78297)

Problems to be solved by the invention

  However, as described in Patent Document 1, it has been found that the strength and rigidity of the coupled hoods are not sufficient only by overlapping and fixing the outer hood and the inner hood, and the drooping can be sufficiently prevented. It also turned out not to be.

  As described in Patent Document 2, if a reinforcing grid-like knitted structure is fixed between the outer hood and the inner hood, sufficient strength and rigidity can be secured, and drooping of the connecting hood can be suppressed. However, high-strength aramid fibers such as “Technola” have a drawback in that they are expensive.

As a result of intensive studies on the use of a high-priced high-strength aramid fiber, the inventors have used polyethylene terephthalate (PET) filaments for the warp of the base fabric used for the outer hood and polyester for the weft. Use filament ,
In addition, when the warp yarn has a property that is superior in tensile strength and dimensional stability than the weft yarn, and the weft yarn is composed of a filament having a property superior in tensile modulus to that of the warp yarn , It was found that sufficient strength, rigidity and displacement adaptability were ensured for use, and would not hang down when used in a connected hood. These filament materials are less expensive than high-strength aramid fibers, and it is only necessary to replace the base cloth of the conventional outer hood with these two types of filaments, and it is necessary to add additional reinforcing fibers. It turns out that there is no.

The present invention, as a hood for a connecting hood, has sufficient strength, rigidity, and displacement adaptation that can flexibly adapt to displacements such as up, down, left, right, twist, and front-rear direction that occur between running knitting vehicles. It is an object of the present invention to provide a hood cloth for a connected hood, which can suppress the drooping of the connected hood, is easy to manufacture, can be manufactured at a relatively low cost, and can reduce the weight of the connected hood.
