Abstract

PURPOSE:To obtain a decorative cloth provided with an adhesive layer having no possibility of bleeding through the surface of a base cloth regardless of the kind or configuration of the base cloth in relation to a decorative cloth to be bonded to a base material, such as a metal, a plastic, paper, or cloth, for providing a high-quality feeling to the base material and its production method. CONSTITUTION:An adhesive layer 3 is formed on a surface of a base cloth 2 by transfer coating. For the adhesive layer 3, a hot melt adhesive mainly composed of a thermally-coherent thermoplastic resin is used. A resin coating film 4 formed by applying an adhesive liquid to release paper is transferred to the base cloth 2, thereafter being thermally treated to be shrunk. In this manner, the adhesive layer 3 having a large number of through holes 5 corresponding to the meshes of the base cloth 2 is formed. When a polyvinyl chloride punched sheet is used as a base material, a polyester resin, a nylon resin, or a polyurethane resin each having a melting point of 60 to 110 deg.C is used as the thermally-coherent thermoplastic resin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative cloth which is attached to a base material such as metal, plastic, paper or cloth to give a high quality feeling to the base material and a method for producing the same.

[0002]

2. Description of the Related Art There is a speaker net which covers the front surface of a speaker, a cover of a book, or the like, which is dyed on a surface of a base material to give a high-class feeling. In particular, it is necessary to use a dyed woven fabric with a rough texture in the manufacture of a speaker net that requires acoustic properties and translucency (a sense of transparency), and an adhesive that bonds the base material and the dyed woven fabric to the surface of the dyed woven fabric. Care must be taken not to seep out.

Conventionally, as a sheet material for a speaker net, a material coated with aluminum punching metal or a dyed fabric has been used. The former has the disadvantage that the manufacturing cost is high and the weight of the entire speaker increases because it is a product made by punching and painting an aluminum plate, and it cannot be formed into a complicated shape. It has the drawback of limiting the design.
The latter has no such drawbacks, but has the drawback that the work of attaching it to the speaker frame is troublesome and the productivity is extremely poor, and that the dyed fabric shrinks or relaxes after attachment, resulting in poor appearance. There is.

Therefore, as a sheet material for a speaker net which solves the above-mentioned drawbacks, a punching sheet made of polyvinyl chloride and a decorative cloth bonded to it has been proposed.
This decorative fabric is manufactured by applying an adhesive to the entire surface of a dyed fabric (base fabric) and bonding it to a punching board made of polyvinyl chloride. However, there is a problem that the type and structure of the base cloth are limited because the adhesive cannot be applied uniformly and without bleeding to the front side. In addition, even if the base cloth has an ordinary density, the adhesive that melts when it is attached to the punching sheet exudes to the surface of the base cloth, and it is impossible to obtain a high-quality speaker net sheet material. There's a problem.

The present invention aims to solve the above problems, and provides a decorative fabric having an adhesive layer which does not exude on the surface of the base fabric, regardless of the type and structure of the base fabric, and a method for producing the same. Is intended.

[0006]

The decorative cloth of the present invention comprises a base cloth 2 and an adhesive layer 3 formed on the surface thereof by transfer coating. The adhesive layer 3 is formed by forming a large number of through holes 5 in a resin coating 4 of a hot-melt type adhesive containing a thermocohesive thermoplastic resin as a main component. When using a polyvinyl chloride punching sheet as the base material,
As a thermo-cohesive thermoplastic resin, a polyester resin,
A thermoplastic resin having a melting point of 60 to 11 selected from nylon resin and polyurethane resin.
Use 0 ° C.

In the method for producing a decorative cloth of the present invention, a hot-melt type adhesive liquid 10 containing a heat-cohesive thermoplastic resin as a main component is prepared, and the adhesive liquid 10 is evenly applied to the release paper 9. The resin coating 4 is formed by transferring the resin coating 4 to the base fabric 2 and then heat-treated to shrink the resin coating 4 to form the adhesive layer 3 having a large number of through holes 5. In particular, the thermocohesive thermoplastic resin is one thermoplastic resin selected from polyester resins, nylon resins, and polyurethane resins and has a melting point of 60.
It is preferable to prepare a hot-melt type adhesive liquid having a temperature of 110 to 110 ° C. as a main component.

[0008]

The decorative cloth 1 of the present invention has the resin film 4 of the hot-melt adhesive having a large number of through holes 5 on the surface of the base cloth 2, and the base material such as a synthetic resin sheet is formed by heating and pressing. Material 1
5 can be easily glued. Hot melt adhesives are mainly composed of thermocohesive thermoplastic resin,
Since the adhesive does not seep out to the surface of the base cloth 2 in the bonding step, it is possible to obtain a high-quality speaker net sheet material, book cover, etc. while maintaining the acoustic effect and the sense of scale. As the hot-melt adhesive, if one thermoplastic resin having a melting point of 60 to 110 ° C. is selected from among polyester resin, nylon resin and polyurethane resin having heat aggregability, It can be easily adhered to the punching sheet 15 made of polyvinyl chloride.

In the manufacturing method of the present invention, the resin coating 4 of the hot melt adhesive is transferred onto the base cloth 2, so that the resin coating 4 does not penetrate into the inside of the tissue of the base cloth 2. Further, since a heat-cohesive hot-melt adhesive is used, a large number of through holes 5 can be easily and reproducibly formed by transferring the resin coating 4 to the base cloth 2 and then heat-treating it to shrink the resin coating 4. Can be formed. Therefore, even if the adhesive layer 3 is melted in the step of adhering the decorative cloth of the present invention and the punching sheet 15 made of polyvinyl chloride, the resin does not exude onto the surface of the base cloth 2. When the punching sheet 15 made of polyvinyl chloride is used as the base material of the speaker net sheet material, a hot-melt adhesive having a melting point of 60 to 110 ° C. is adopted.
