Abstract

Provided is a protective cover such as a hose processed so as not to unravel the end.
A protective cover 10 such as a hose 11 is a woven or knitted tubular body made of nylon or polyester, and a cut end 13 in a longitudinal direction is heat-processed or resin-processed. Thermal processing is, for example, heat setting with a pin tenter, iron, high-temperature and high-pressure steamer, or formation of a melted part by cutting a high-temperature knife or wire. Resin processing is, for example, end formation by resin coating or impregnation.

Description

  The present invention relates to a protective cover for hoses, metal pipes, cables, etc. (hereinafter referred to as “hose etc.”).

Conventionally, protect the hose from heat damage, wind erosion, water damage, etc., prevent heat damage and noise generated from the hose, etc., prevent oil leakage and scattering of leaked oil, move the hose etc. A protective cover made of woven fabric or knitted fabric is used so that the surface of other articles is not rubbed and damaged when it is being worn.

As such conventional techniques, for example, Japanese Patent Laid-Open No. 2000-283382 and Utility Model Registration No. 3028117 are known. The former is intended to quickly cover and fix a cable or the like in a narrow place where only one hand can be inserted, and the latter is characterized by a fixing method to the hose.

JP 2000-283382 A Utility model registration No. 3028117

  Although not mentioned in the above prior art, this type of protective cover has the following problems. When the protective cover is attached to a hose or the like, it is necessary to cut the long cylindrical protective cover according to the length of the hose or the like. Conventionally, it was cut with scissors or a cutter, but since the protective cover is a woven fabric or a knitted fabric, the end portion may be unwound from the cut surface. When the end of the cover is forcibly covered with a hose or the like, it becomes difficult to tightly hold the tubular contents such as the hose in a desired form. Further, such fraying of the end is not desirable in appearance.

  In order to cope with this problem, the present invention aims to provide a protective cover such as a hose that has been processed so as not to unravel the ends.

  The present invention is a tubular body of woven or knitted fabric made of nylon, polyester, or heat-welded yarn, and its longitudinal cut end (cut surface and its periphery) is heat-processed or resin-processed. It is a protective cover such as a characteristic hose.

  As the heat-welding yarn, nylon heat-sealing yarn (for example, “Elder (registered trademark)” of Toray Industries, Inc.) that melts entirely at a low melting point of 110 to 120 ° C., polyethylene and polypropylene, polyester and polyethylene, polyester And materials having different melting points such as low melting point polyester and the like, which are spun into a single fiber in a state of a core and a sheath, can be used.

  Examples of the thermal processing include heat setting with a pin tenter, iron, high-temperature and high-pressure steamer, etc., or formation of a melted portion by high-temperature knife or wire cutting.

  Examples of resin processing include edge formation by resin coating, impregnation, film processing, laminating, and the like.

  According to the present invention, since the cut end portion in the longitudinal direction of the protective cover such as a hose is heat-processed or resin-processed, the end portion cannot be easily unwound.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

(A) is a perspective view of the hose cover in one Example of this invention. (B) is a perspective view of a conventional hose cover.

  The hose covers 10 and 10A shown in FIGS. 1 (a) and 1 (b) are woven fabrics made of nylon (for example, nylon 66) or polyester yarn, and both end portions 14 and 14A in the width direction are sewn together. It is an elongated cylindrical body. Depending on the diameter of the hoses 11 and 11A to be attached, several types of diameters are prepared, such as 12.5 cm and 16.0 cm.

As shown in FIG.1 (b), the hose cover of a prior art is only cut | disconnected with the scissors and the cutter, and the cut end has come off from 12A of cut surfaces.

As shown in FIG. 1A, in the embodiment of the present invention, the cut end of the cut surface 12 is not unwound. In order to obtain such a cut surface, the present invention performs the following treatment.

(1) Heat set at least the cut end of the hose cover.

As a preferable heat treatment apparatus used for heat setting, a pin tenter, an iron, and a high-temperature / high-pressure steamer are exemplified. The heat set temperature varies depending on the material of the hose cover to be used and is not particularly limited. For example, when the material of the hose cover is nylon 66 or polyester yarn, it is preferably 130 to 190 ° C. The time is preferably 30 seconds or more, and preferably 90 seconds or less in consideration of productivity. Under such heat setting conditions, the hose cover can be uniformly heat set without causing fusion. it can.

(2) The hose cover is cut with a high-temperature knife or wire (heating wire) to obtain a fused cut surface.

As a result, the single fibers are fused to prevent the cut surface from being loosened or unraveled.

(3) Resin the end of the hose cover.
The resin used for processing the resin is not particularly limited as long as it is removed by an organic solvent, and as a processing method, any processing method can be used as long as it is substantially adhered, penetrated, and integrated with the material fiber. Processed resin may be used. Examples of the resin used include polyurethane resins and silicone resins. The processing methods include coating, impregnation, film processing, laminating, etc., and a laminate of a sheet or film that has been infiltrated with a molten resin or resin solution and adhered, adhered or infiltrated to the fiber surface. Etc.
