[Industrial applications]

 The present invention relates to a transparent polyvinyl chloride resin mirror surface non-tack treatment sheet that eliminates the so-called tack tack phenomenon of a transparent polyvinyl chloride resin mirror surface laminated on the surface of a fabric sheet.

[0002]

[Prior art]

 Conventionally, a transparent polyvinyl chloride (PVC) resin film is laminated on the surface of a cloth sheet such as cloth cloth, printed cloth cloth, non-woven cloth, paper, and print-impregnated paper to show specular gloss. In this way, the treated surface, which has a mirror-like gloss on the surface of the dough sheet, is uncomfortable to touch because it causes a so-called stickiness (tack) phenomenon, and the sheet is processed into a table cloth or bag. When using it, it feels bad not only during production but also during use. In particular, when the surfaces contact each other, they stick together and are difficult to handle.

Furthermore, in the case of a table cloth, when a glossy tea bowl, plate, stationery, etc. is placed on the surface of the table cloth, the contact surface sticks to it, and printed books such as magazines and newspapers are used for a long time. If left unattended, the transfer of ink to the surface of the table cloth tends to occur due to the transfer of the plasticizer that is heavily compounded in the transparent polyvinyl chloride resin, and the book will stick to the surface. There are obstacles such as closing.

In the case of a bag such as a fashion bag, when the sheet is cut and sewn and the mirror glossy surfaces come into contact with each other by folding or the like, the contact surfaces stick to each other or the slippage is poor, so that the bag is free. Not only does it have poor handling, and the sewing machine is not slippery at the stage of stitching, which adversely affects the sewing efficiency, but when the bags are piled up, they stick to each other or are used as polyethylene packaging bags. However, there are some drawbacks, such as sticking, slippage, and difficulty in inserting.

[0005]

[Problems to be solved by the device]

 The present invention is manufactured by applying a conventional laminating process to maintain the above-described specular gloss state, eliminating the sticky phenomenon (tack), displaying a dry state (non-tack), and providing flexibility. The objective is to obtain a non-tack-treated sheet of transparent polyvinyl chloride resin mirror surface that is easy to handle in use and has a good feel.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of the above point of view, and a transparent polyvinyl chloride resin film laminated on the surface of a cloth sheet is provided with a concave or convex portion of a desired size and shape on the surface of a mirror-finished roll. It is intended to provide a non-tack-treated sheet of transparent polyvinyl chloride resin mirror surface obtained by transferring the surface shape of an embossing roll in which a number of parts are arranged.

[0007]

[Action and Example]

 An embodiment of the present invention will be described below along with its operation. The embossing roll to be used is finished by buffing the surface of the iron core, which is surface-polished and mirror-finished as in the conventional case. As shown in FIGS. 1 and 2, the embossing roll 1 has a surface on which a pattern composed of a large number of lattice-shaped slots 2 is formed. The slot 2 may have various shapes such as a round shape, a triangular shape, a trapezoidal shape, and a pyramid shape other than the lattice type.

The size of the lattice type slot 2 is, for example, one side length l = 0.2 mm, pitch interval L = 0.4 mm, and depth (emboss depth) D = 0.08 mm. ing. Therefore, per 1 cm ^{2 of} the roll surface, the number of grooves is (10 / 0.4) ² = 625 (pieces) The groove hole area is 0.2 ² × 625 = 25 (mm ² ) Area ratio (area of groove hole 2 The area of the surface flat portion 3) is 25: 75 = 1: 3.

Regarding the size of the above-described slot 2, the length of one side or diameter is usually about 0.05 mm to 0.5 mm, the pitch interval is about 0.1 mm to 1 mm, and the emboss depth is 0.01 mm to 0. It is preferable to have a uniform arrangement of about 15 mm, but there is no particular problem even if the arrangement is non-uniform. Further, as the size of the slot 2 becomes smaller, the area of the flat portion 3 becomes larger and the gloss tends to appear, while the stickiness tends to occur.

By pressing the embossing roll 1 against the transparent polyvinyl chloride resin film 11, the surface of the embossing roll 1 has a transparent polyvinyl chloride resin film 11 as shown in FIG. Then, the groove 2 is inverted and a peak portion 12 having a height of 0.08 mm corresponding to the depth thereof is formed to project, and the portion contacting the flat portion 3 becomes a mirror surface 13.

In the above-mentioned embodiment, the embossing roll is provided with the groove and the mountain-like protrusion is formed on the transparent polyvinyl chloride resin film. However, the concavo-convex relationship is reversed. You may.

[0012]

[Effect of device]

 As is apparent from the above description, according to the present invention, innumerable recesses or protrusions are provided on the surface of the embossing roll for the transparent polyvinyl chloride resin film adhered to the surface of the cloth sheet. Since it shows a mirror gloss while transferring the shape of, the stickiness disappears due to the innumerable recesses or protrusions formed on the surface while maintaining the mirror gloss state. It becomes a state and becomes flexible. Therefore, even when the non-tuck treated sheet according to the present invention is manufactured as a material, and when the manufactured product is used, it is easy to handle and has a good feeling.
