JPH0577599A - Surface treatment process such as metal glossing of air permeable sheet - Google Patents

Abstract

PURPOSE:To ensure that surface processing is performed as specified by masking so that a specified surface process such as metal evaporation, sublimated transfer or printing does not affect another surface adversely in case such a surface process is desired for the treatment of one surface or both surfaces of an air permeable sheet. CONSTITUTION:The adhesive surface 21 of an adhesive sheet B is placed over the one surface of an air permeable sheet such as woven cloth, unwoven cloth or a perforated sheet and both are adhered together temporarily by pressing with the subsequent masking of the surface using an adhesive sheet as a masking process. In addition, a surface treatment process which applies any appropriate surface treatment to a desired area on the other surface of the air permeable sheet with one masked surface as seen in a metal evaporation layer 12, and a peel-off process which peels the adhesive sheet apart from the air permeable sheet after surface treatment, are provided.

2. Description of the Related Art As a conventional surface treatment method such as metallic luster finishing of a breathable sheet, as shown in FIG.
Woven fabric formed by weaving fibrous bodies 1 such as filaments obtained by spinning natural fibers or synthetic fibers, or nonwoven fabric formed by connecting and joining fibrous bodies 1 such as natural fibers and synthetic fibers into a sheet shape. When it is desired to apply the metal vapor deposition layer only to one surface of the breathable sheet A, the metal vapor 3 generated by heating a metal such as aluminum at a high temperature is supplied from one side of the breathable sheet A, and the ventilation is performed. The metal vapor deposition layer 2 is applied to a portion of the fibrous body 1 constituting the air-permeable sheet A corresponding to one surface side of the breathable sheet A.

[0003]

By the way, the air-permeable sheet A and the fibrous body 1 have a small space 5 for allowing air to pass therethrough.
Since it has air permeability, the metal vapor 3 supplied from the one surface side M of the air permeable sheet A passes through the space portion 5 and wraps around to the other surface side L to the metal vapor deposition layer 2, The wraparound metal vapor deposition part 4 is likely to occur on the other surface side L. Therefore, from the other surface side L of the breathable sheet A, the metal vapor deposition layer 2
Was observed, and it was difficult to perform the surface treatment so that the metal vapor deposition layer 2 can be observed only from the one surface side M which is the supply side of the metal vapor 3.

According to the present invention, when one or both surfaces of the breathable sheet A are desired to be subjected to a predetermined surface treatment such as a metal deposition process, a sublimation transfer process and a printing process, the influence of the process is exerted on the other side. The purpose is to mask it so that a predetermined surface treatment can be performed.

[0005]

The first invention of the present invention is as follows:
A masking step of overlaying the adhesive side of the pressure-sensitive adhesive sheet on one side of the breathable sheet such as woven cloth, non-woven fabric or perforated sheet, temporarily attaching while applying pressure, and masking with the pressure-sensitive adhesive sheet, and the above-mentioned ventilation with one side masked. Breathability characterized by including a surface treatment step of appropriately performing a surface treatment on a desired region on the other surface side of the air-permeable sheet, and a peeling step of peeling the pressure-sensitive adhesive sheet from the breathable sheet after the surface treatment. It is a surface treatment method such as sheet metal gloss treatment.

Further, the present invention is based on the first invention.
The surface treatment step is a metal vapor deposition step, or a colored picture in which the metal vapor deposition step and a coloring ink such as a transparent color ink or an opaque color ink that is performed after the step are used to completely or partially color and paint. It is a surface treatment processing method such as a metallic luster processing of the breathable sheet which is a attaching step.

The second invention of the present invention is to provide, after the masking step, the surface treatment step and the peeling step,
A masking step of stacking the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet on the other surface side of the breathable sheet, temporarily adhering it while applying pressure, and masking with the pressure-sensitive adhesive sheet; and one surface side of the breathable sheet with the other surface side masked. A surface treatment step of appropriately subjecting the air-permeable sheet to a surface treatment step, and a peeling step of peeling the pressure-sensitive adhesive sheet from the air-permeable sheet after the surface treatment step. Is.

The present invention is the same as the second invention,

EXAMPLES The method of the present invention will be described in detail according to examples. 1 (a) to 1 (d) are side views for explaining an embodiment of the first invention of the present invention, and FIGS. 1 (a) and 1 (b) are
Fig. 3 illustrates a masking step, which is a nonwoven fabric in which the fibrous body 11 is connected in a sheet shape to the adhesive surface 21 of the adhesive sheet B,
Alternatively, a woven fabric obtained by weaving the filamentous fibrous body 11 into a sheet, or a perforated sheet having a large number of fine holes,
The breathable sheets A are overlapped and appropriately pressed by a pressing means P (a flat press machine of a flat pressure type, a pressure roll of a circular pressure type or the like), so that the fibrous body 11 is relatively soft and adhesive.
1 as shown in FIG. 1 (b).
The fibrous body 11 on the one surface side 14 of the breathable sheet A is covered with the adhesive surface 11 of the adhesive sheet B and its base sheet 20 to mask the breathability and liquid permeability of the breathable sheet A. Is to do.

The pressure-sensitive adhesive sheet B is made of, for example, paper, or a resin-made base material sheet 20 such as polyethylene terephthalate, polyvinyl chloride, polystyrene, polyethylene, acrylic, polycarbonate, thermosetting polyester, or polyurethane. For fibrous materials such as organic or inorganic fibrous ultra-thin sheets, thin paper, non-woven fabric, Japanese paper, or synthetic resin sheets that have a relatively good resin impregnation property,
Natural rubber, styrene-butadiene rubber, acrylic rubber, or a rubber-based pressure-sensitive adhesive to which a tackifier such as polyterpene resin is applied, or an acrylic-based pressure-sensitive adhesive to which a copolymer of butyl acrylate and acrylic acid is applied. A pressure-sensitive adhesive such as a silicone-based or urethane-based pressure-sensitive adhesive is laminated or applied to form the adhesive surface 21.

The thickness of the base sheet 20 can be appropriately set, for example, 0.05 mm to 1 mm, and the thickness is such that the breathable sheet A is flexible enough to be deformed. Alternatively, the breathable sheet A may have such hardness that it is held flat and is not deformed.

The thickness d of the adhesive surface 21 can be changed according to the volume of the fibrous body 11 of the breathable sheet A, but the thickness d is such that about half of the side sectional area of the fibrous body 11 can be buried. It is suitable, for example, when the fibrous body 11 is a material having no or little deformation by the pressing means P, it is set to about half R of the longitudinal diameter 2R of the fibrous body 11, or When the fibrous body 11 is a material that is deformed into a flat shape by the pressing means P, it is appropriate to set it to about half r of the longitudinal diameter 2r at the time of deformation. However, the thickness d is not limited to this, and may be any thickness that allows masking in the direction in which the breathability or liquid permeability of the breathable sheet A is eliminated.

Although the adhesive sheet A has the adhesive sheet 21 provided on the base sheet 20, the adhesive sheet 21 may be omitted without the substrate sheet 20, for example.

Subsequently, FIG. 1A, the breathable sheet A
After temporarily sticking the adhesive sheet B to the one surface side 14 and masking, the both sheets A and B are loaded into a chamber for vapor deposition of a predetermined metal, and in an atmosphere of a predetermined vacuum pressure and temperature,
The vapor deposition metal (aluminum, nickel, chrome, copper, etc.) is heated to a high temperature to radiate the metal vapor, as shown in FIG.
As shown in FIG. 3, the metal vapor 13 is supplied from the opposite side of the surface of the fibrous body 11 to which the adhesive sheet B is adhered for a predetermined time (for example, about 1 minute to 5 minutes) to cover the adhesive surface 21. The metal vapor deposition layer 12 having a thickness of, for example, about 0.001 to 0.1 μm is applied to the other surface side 15 of the fibrous body 11 which is not formed.

Subsequently, the two sheets A and B having the metal vapor deposition layer 12 taken out from the metal vapor deposition chamber are shown in FIG.
As shown in (d), the breathable sheet A is more adhesive than the adhesive sheet B.
By peeling off the adhesive surface 21 and releasing the masking, only the other surface side 15 of the fibrous body 11 of the breathable sheet A is provided with the metal vapor deposition layer 12 having a metallic luster reflection effect,
The breathable sheet A on which the vapor deposition sheet 21 is not vapor-deposited on the one surface side 14 covered with the adhesive surface 21 is obtained.

As an example of the surface treatment step of performing the appropriate surface treatment in the first aspect of the present invention, there is the metal vapor deposition step, but the present invention is not limited to this and the surface cleaning step is not limited to this. Appropriate surface treatment steps such as processing, transfer painting, printing and surface blasting can be applied.

Next, another embodiment of the first aspect of the present invention will be described with reference to FIGS. 2 (a) and 2 (b).
As shown in (a), the metal vapor deposition layer 12 is applied to the other surface side 15 of the breathable sheet A masked by the pressure-sensitive adhesive sheet B, and then the pressure-sensitive adhesive sheet B is not peeled or after peeling the metal. On the surface of the vapor deposition layer 12, a coloring layer 30 is applied to the entire surface by gravure printing or the like with a transparent coloring material having a suitable hue such as yellow, blue or red (for example, a coloring coating coating material, printing ink, etc.), and the coloring material is appropriately selected. After drying, as shown in FIG. 2B, the pressure-sensitive adhesive sheet B is peeled off so that the metal vapor deposition layer 12 serves as a light-reflecting surface, and the breathable sheet A emits colored reflected light colored in an appropriate hue. A sheet material having a decorative property can be obtained.

In FIG. 2A, the metal vapor deposition layer 1
When 2 is an aluminum metal vapor-deposited layer exhibiting a silver color, a transparent yellow ink is printed on the surface of the metal vapor-deposited layer 12 by a gravure printing method or the like to apply a yellow colored silver-colored reflective surface. The breathable sheet A having a golden metallic luster according to the above-mentioned sheet can be obtained as a decorative sheet material.

Further, as shown in FIG. 3, the pressure-sensitive adhesive sheet B is not peeled off to the other side 15 of the surface of the breathable sheet A on which the metal vapor deposition layer 12 is applied, on which the metal vapor deposition layer 12 is applied, or After peeling, the coloring layer 31 is partially applied with an opaque coloring material having an appropriate hue such as yellow, blue, or red (for example, coloring coating coating material, printing ink, etc.) by a gravure printing method or the like, and the coloring material is applied. By appropriately drying and then peeling off the pressure-sensitive adhesive sheet B, a colored layer 31 region (region having no metal reflection effect) made of an opaque coloring material in which the metal vapor deposition layer 12 is hidden and a metal gloss having a light reflection effect are provided. It is possible to obtain a decorative sheet material by an air permeable sheet in which the exposed areas of the metal vapor deposition layer 12 coexist with each other.
