[0001]

[Industrial applications]

 The present invention relates to a cover material for a cover of a book, note, file, book, or the like.

[0002]

[Prior art]

 As the cover of the book, there is a cloth, a cloth lined with thin paper, Japanese paper, or Western paper, and a cloth covered with a thin paper, Japanese paper, or Western paper, and then attached to thick paper.

When the cloth is used, the thread is unraveled from the cut end to damage the cover and it is unsightly, and the cover is warped (curl) under the influence of temperature and humidity changes. Sometimes. In addition, when the cloth is lined with thin paper, the cloth does not adhere well to the backing paper when the cloth is a synthetic fiber cloth such as polyester, and when the cloth is used as the cover, the cloth is upside down. It may come off from the edge. Furthermore, when the paper-lined cloth is attached to cardboard, the cloth part may peel off from the koba.

[Problems to be solved]

 The present invention is intended to eliminate the drawbacks of the related art, to provide a durable, easy-to-make, and good-looking product economically.

[0005]

[Means for solving the problem]

 In the present invention, a base cloth is subjected to a water repellent treatment, and a synthetic resin layer such as a thermoplastic synthetic resin is formed on the surface of the base cloth. A pigment is added to the synthetic resin layer so that various colors can be easily colored.

[0006]

[Example] What is shown in the figure is a cover surface covering material for mounting a cover of a book, and the covering material has a base cloth (1). As the base cloth, natural fiber such as cotton, hemp or the like, synthetic fiber such as nylon or polyester, non-woven fabric or other suitable cloth is used. In addition, in the case of natural fiber, desizing, scouring, and bleaching are appropriately performed.

A water repellent treatment is applied to the base cloth. For the water repellent treatment, it is preferable to use paraffin emulsion for natural fiber and fluororesin emulsion for synthetic fiber.

An example of water repellent treatment is shown in FIG. The base fabric (1) is guided through a roller (4) into a container (3) containing a water repellent finish liquid (2), and the base fabric is impregnated with the water repellent finish liquid. Excess water-repellent processing liquid that has penetrated into the base material is squeezed and removed by the mangle (5). After finishing the water repellent treatment, the base cloth is dried.

After drying, the synthetic resin liquid (6) is uniformly applied to the surface of the base cloth. An example of the application is shown in FIG. The base cloth is sent to the synthetic resin liquid container (9) by the front guide roller (7) and the rear guide roller (8), and the roller (10) immersed in the synthetic resin liquid in the container is removed. The synthetic resin liquid is applied to the surface (11) of the base fabric via the above to form a synthetic resin layer (12). The applied resin liquid is made flat and uniform by a doctor knife (13). When the synthetic resin liquid is applied to the surface of the base cloth, the water repellent treatment is applied to the base cloth in advance as described above. Therefore, as shown in Fig. 3, the resin liquid is mixed with warp threads (14) and weft threads (15). The back surface (16) of the base cloth does not penetrate, and the resin liquid does not unnecessarily enter the inside of the base cloth.

The above synthetic resin liquid uses an acrylic ester resin emulsion in the examples, but in addition to this, urethane resin, vinyl chloride, EVA resin, vinyl acetate resin, synthetic rubber, and A thermoplastic synthetic resin such as a polymerized emulsion can be used. The synthetic resin liquid is appropriately mixed with a crosslinking agent, a catalyst, a thickener and the like, and in the case of coloring, a pigment is mixed.

After applying the synthetic resin liquid to the base cloth, it is dried with hot air (about 140 ° C.) or the like, and then heat-treated. By this heat treatment, the synthetic resin liquid is formed into a film and fused and firmly adhered to the base cloth. In this example, the heat treatment is performed by heating at about 160 ° C. for about 30 seconds, but this condition can be appropriately changed depending on the type and thickness of the synthetic resin liquid.

[0012]

[Effect of device]

 In the present invention, the synthetic resin layer is formed on the surface of the base cloth. Therefore, unlike the case of using only the base cloth, the synthetic resin layer can be directly printed or printed. The printing can be made strong and beautiful, and the heat transfer foil stamping work can be done easily. Furthermore, the synthetic resin layer can prevent the base cloth from fraying and prevent the cover from curling (curling). Even if the cover is stained with hand stains, the surface is made of synthetic resin, so you can wipe it off immediately and cleanly. Further, since the base cloth is subjected to a water repellent treatment, when the synthetic resin liquid is applied to the surface of the base cloth, the resin liquid does not penetrate to the back surface of the base cloth and a resin layer can be formed on the back surface. Since it is not present, it can be easily and reliably adhered when the base cloth is directly attached to the cover. Further, by forming a thermoplastic synthetic resin layer, it can be heated and firmly bonded integrally to the base cloth. In addition, coloring can be easily performed by adding a pigment to the synthetic resin, and unlike the case of coloring by dyeing the base cloth, an expensive dyeing device or dye is not required, which is economical.
