Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative body having a rod-shaped substrate surface coated with cloth and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, there has been known a method of coating a rod-shaped substrate surface such as a barrel of a writing instrument with a cloth body in order to improve its decorative effect. Since the ends of the overlapped fabrics are adhered to each other by wrapping them around a rod-shaped substrate surface, the joints of the fabrics are formed, the decorative effect is deteriorated, and the fabric is peeled from the joints. There was a problem such as being lost.

Therefore, the present applicant previously made the following proposal in Japanese Patent Laid-Open No. 1-316296 in order to solve these problems. That is, the contents thereof are "a decorative body in which a rod-shaped base body and a seamless tubular cloth body covering the surface of the base body are integrated via an adhesive layer" and a manufacturing method thereof.

[0004]

However, in the above proposal, there are problems such as the above-mentioned "a seam of the cloth is formed, the decorative effect is deteriorated, and the cloth is peeled from the seam". Although the points can be eliminated, it is preferable to form the pattern of the cloth body at the time of forming the cloth body from the viewpoint of the decorative effect, and there is room for improvement in that the variation of the pattern such as the pattern formed on the surface of the cloth body is reduced. It was left.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a decorative body which has an excellent decorative effect and which can expand the variation of the pattern on the surface of the cloth body as much as possible. A rod-shaped substrate, a tubular cloth body having a seamless pattern covering the surface of the substrate through an adhesive layer and having a pattern formed by adsorbing a sublimable dye, and a transparent cloth body covering the cloth body. The first object is a decorative body composed of a resin coating, and a hot-melt type adhesive is applied to the surface of a rod-shaped base body, and then the base body is inserted into a seamless tubular cloth body. The cloth is adhered to the base by pressing the cloth and the base while heat-melting, and then a desired character, figure, or other pattern is formed on the cloth by a transfer sheet coated with an ink containing a sublimable dye on the base. Transfer to the The second gist of the present invention is a method for producing a decorative body in which a resin is pressed against a surface of a cloth including the pattern and a transparent resin coating is formed on the surface of the cloth, and a hot-melt adhesive is applied to the surface of a rod-shaped substrate. After coating, the substrate is inserted into a seamless heat-shrinkable tubular cloth body, and the cloth body is adhered to the base material by heat-melting the adhesive, and thereafter the base contains a sublimable dye. A pattern such as a desired character or figure is transferred to the cloth by a transfer sheet coated with ink, and then the pattern is heated and pressure-bonded, and a transparent resin coating is further applied to the surface of the cloth including the pattern. A third gist is a method of manufacturing the formed decorative body.

The substrate is a rod-shaped member made of metal such as iron, copper, aluminum or zinc, or an alloy thereof, ceramics, glass, resin or the like. A plating layer may be provided by electroplating, electroless plating, etc., or chemical conversion treatment, coating, screen printing, etc. may be performed. The shape may be a hollow body or a solid body. The shape of the cross section is appropriate such as a circle, an ellipse, or a polygon, and may have some taper in the longitudinal direction.

As the adhesive forming the adhesive layer on the surface of the rod-shaped substrate, solvent-type or solvent-free hot-melt type adhesives are used. In consideration of workability, etc., solvent-type hot-melt type adhesives are used. Is preferred. In addition, the melting point of the hot-melt adhesive should be lower than the softening point of the substrate, and a curing agent may be contained in the hot-melt adhesive.

As the cloth body coated on the adhesive layer, cotton,
Natural fibers such as hemp and silk, carbon fibers, inorganic fibers such as glass fibers, metal fibers such as stainless steel, copper, nickel and iron,
Cellulose type, polyamide type, polyvinyl alcohol type, polyvinylidene chloride type, polyvinyl chloride type, polyester type, polyacrylonitrile type, polyethylene type,
Polypropylene-based, polyurethane-based, polyalkylene-para-oxybenzoate-based, phenol-based, polyfluorethylene-based, etc. chemical fibers, etc. can be used alone or in combination of two or more types to form a seamless tubular cloth. It was done. Some of the fibers do not adsorb sublimable dyes, but in the case of such fibers, treatment such as resin coating may be appropriately performed. As the cloth body, a cloth body made of fibers having shrinkability by heat treatment (specifically, Teviron (manufactured by Teijin Ltd.)) may be used, or a cloth body having such heat shrinkability may be used. It is also possible to use a cloth body made by mixing fibers with other fibers having no heat shrinkability. The use of this heat-shrinkable cloth body makes it possible to shrink the cloth body by heat treatment and to adhere to the base material. It also has the effect that it can be possible. Further, the cloth may be dyed.

In order to prevent unwinding of the longitudinal end portion of the cloth body adhered to the surface of the substrate, the end portion of the cloth body made of chemical fiber is heated to be fused or the end portion of the cloth body is fixed. It may be sandwiched between the base body and the mounting member. Various surface states can be obtained by appropriately selecting the thickness of the adhesive layer or the cloth.

A transfer sheet having a base coated with an ink containing a sublimable dye will be described. As the ink, known sublimation dyes represented by disperse dyes are polyvinylpyrrolidone, hydroxypropyl cellulose, polyvinyl methyl ether, acryl-acetate cellulose system, vinyl chloride, methyl cellulose / vinyl acetate copolymer, polyamide resin. A mixture with a thermoplastic resin such as chlorinated rubber is used, and a solvent, a surfactant and the like are appropriately added. This ink is coated on a base made of paper, heat resistant resin film or the like by an offset printing method or the like to form a transfer sheet.

By using the transfer sheet, the cloth body forms a desired pattern of characters, figures, etc. by adsorbing the ink. The surface including the pattern of the cloth body has a stain on the surface of the cloth body. For the purpose of prevention and prevention of peeling of the pattern, clear coating such as thermoplastic acrylic, melamine, urethane, fluorine, and silicone, thermosetting acrylic, melamine, urethane, fluorine, A resin coating is formed by a known clear coating layer such as a silicon-based clear coating or a coating layer such as a transparent film.

Next, a method of manufacturing the decorative body according to the present invention will be described. First, the rod-shaped base body and the cloth body are integrated, and the following two methods can be mentioned as the method. In the first method, a hot-melt adhesive is applied to the surface of a rod-shaped substrate by spraying or a roll coater, and the hot-melt adhesive is dried to form a seamless tubular cloth body. Insert it, heat it with a hot plate, heat roller, etc. to melt the adhesive and apply pressure,
A method of integrating a base body and a cloth body, or a method of inserting a base body coated with a cloth body into a rubber hollow body having heat resistance, and heating and pressurizing from the outer surface of the rubber hollow body to melt the adhesive, It is a hot pressing method that integrates the body. still,
In the present method, for the purpose of forming a layer of an adhesive having a uniform thickness on the surface of the substrate, reducing the partial adhesive force caused by the unevenness of the layer of the adhesive on the surface of the substrate, and preventing wrinkling of the cloth,
Pre-bonding may be performed before the heat and pressure treatment. This pre-bonding treatment is carried out by heating to melt the adhesive layer to a uniform thickness and temporarily adhering the cloth body to the surface of the substrate, or as in the case of the cloth in a rubber hollow body having heat resistance as described above. A method such as a hot press treatment in which a barrel covered with a body is inserted and thermocompression bonding is used.

The second method is a method in which a cloth body that shrinks by heat treatment is used as the cloth body, and a hot-melt type adhesive is applied to the surface of a rod-shaped substrate by a spray, a roll coater or the like. , Dry, insert this into a seamless heat-shrinkable tubular body, heat-treat it to melt the adhesive and heat-shrink the fabric,
This is a method of integrating the base body and the cloth body. This method
Since the cloth body comes into close contact with the substrate due to thermal contraction, there is no need to apply pressure from the surface of the cloth body, and there is an advantage that the adhesive agent is melted and the cloth body is brought into close contact with the substrate simply by putting it in a heating atmosphere. ..

Next, a pattern forming method will be described. First, prepare a transfer sheet in which a pattern corresponding to a desired character, figure, or the like pattern is formed from the ink, place the sheet on the surface of the cloth so that the ink and the cloth come into contact with each other, and heat from the base side. When pressure-bonded, the base ink is transferred to the cloth body to form a pattern on the cloth body. In addition, it is a preferable example to use a heated plate for pressure bonding while heating from the base side.
Further details will be described below based on Examples.
