Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a patterned fabric with a cell-like pattern used for bags, wallpaper, flooring, etc., and a method for manufacturing the same.

(Prior art) Conventionally, cell-like patterns, so-called cell structure patterns, arranged in a continuous manner as patterns used for bagging and the like have not yet been known, but there are similar patterns, such as suminagashi processing. A suminagashi pattern using a method is known, and this suminagashi pattern is created by floating multiple inks of different colors on the water surface and transferring these inks to the fabric side.
A pattern consisting of multiple different colors is created.

(Problem to be Solved by the Invention) However, when forming a suminagashi pattern using the suminagashi processing method described above, it has the advantage that it is not possible to reproduce the same pattern, but on the other hand, it is possible to create extreme color tones due to subtle changes in processing conditions. Suminagashi processing requires skill because of the changes that occur, and furthermore, it is not possible to create a large number of consecutive suminagashi patterns of the same color.
There were problems such as the products that could be used were limited to small ones.

As a result of continuing research to obtain new pattern areas based on the above viewpoints, the present inventor has discovered that when a pigment with a flat structure is mixed into a synthetic resin and wind pressure is applied to the synthetic resin, It was discovered that the direction in which the pigments are arranged changes, and as a result of this change in the arrangement of the pigments, a cell-like pattern is formed that includes a glossy area and a critical area that has a different gloss than the glossy area. .

Therefore, the first object of the present invention is to obtain a patterned fabric that exhibits a cell-like pattern, which has not been known in the past.

A second object is to manufacture the cell-like pattern by a simple manufacturing means, and also to produce a pattern that exhibits a cell-like pattern of the same color tone without being able to reproduce the same pattern.

(Means for Solving the Problems) As shown in the embodiments of the drawings, the patterned area exhibiting the cell-like pattern according to the present invention is made of a synthetic resin R mixed with a pigment P having a flat structure, and is made of a sheet The pigment P in the synthetic resin layer 1 formed into a shape
are arranged in a certain direction, and the pigment P is arranged in a direction different from the arrangement direction of the pigments P in the glossy part 1a, and the glossy part 1
The material is characterized by having a critical portion 1b having a different gloss from the critical portion 1a.

In addition, the method for manufacturing the patterned area in which the cell-like pattern was obtained is that after holding a liquid synthetic resin R mixed with a pigment P having a flat structure in a sheet form, and before curing the synthetic resin R, it is made into a sheet form. The arrangement of the pigments P is changed by applying wind pressure to the liquid synthetic resin R, and before the arrangement of the pigments P is restored to a stable position, the sheet-shaped synthetic resin R is cured. It is something to do.

As the synthetic resin R used in the present invention, transparent or translucent liquid type resins such as vinyl chloride resin, silicone resin, epoxy resin, urethane resin, and ultraviolet curing resin are used.

Further, as the pigment P having a flat structure mixed in the synthetic resin R, for example, a pearl pigment made of natural mica coated with rutile-type titanium, or a metal pigment made of scale-like aluminum, etc. are used.

(Function) Although the detailed principle behind the appearance of the cell-like pattern is still unclear, it can be roughly inferred as follows: The pigment in the liquid synthetic resin R held in a sheet form Since P has a flat structure, under normal conditions it is arranged in an orderly manner in the horizontal direction as shown in Figure 4 A, but when wind pressure is applied to the outer surface of the synthetic resin R, At this time, as shown in FIG. The arrangement is disturbed, and the pigment P located at the wave crest a is vertically erected, and in the area other than the wave crest a, the pigment P is
is held horizontally.

Further, after applying wind pressure to the outer surface of the synthetic resin R as described above, by curing the synthetic resin R before the pigment P erected at the wave crest a returns to a stable state, that is, a horizontal state, Pigments P arranged in an upright manner in this synthetic resin R,
Pigments P arranged horizontally are formed.

Since the horizontally arranged pigments P have a good reflectance to external light, they form a glossy part 1a with a predetermined luster, and the vertically arranged pigments P have a good reflectance to external light. Since the reflectance of the critical area 1a decreases, the critical area 1b has a different gloss from the glossy area 1a, and in other words, the glossy area 1a is arranged inside the critical area 1b. Due to these glossy areas 1a and critical areas 1b, a cell-like pattern appears continuously on the synthetic resin layer 1.

(Example) Hereinafter, a patterned area in which a cell-like pattern according to the present invention appears will be explained by referring to an example of the drawings.

The patterned area shown in FIGS. 1 and 2 is made of a liquid synthetic resin R mixed with a pigment P having a flat structure consisting of a pearl pigment or a metal pigment.
Formed into a sheet shape to form a thin and long synthetic resin layer 1
A glossy part 1a is formed on this synthetic resin layer 1 with the arrangement direction of the pigment P aligned in the horizontal direction.
and a critical region 1b having a gloss different from that of the glossy region 1a, which is formed by aligning the arrangement direction of the pigment P in a substantially perpendicular direction. A cell-like pattern appears on the outer surface of the synthetic resin layer 1.

Although not shown in the drawings, it is also possible to attach a base material such as cloth or rigid resin to the lower surface of the synthetic resin layer 1.

As shown in FIG. 3, the patterned area is formed by forming the synthetic resin layer 1 into an arbitrary sheet shape, fixing the synthetic resin layer 1 to a long sheet 2 on the surface side as a skipped pattern, and forming the synthetic resin layer 1 into an arbitrary sheet shape. It is also possible to make a predetermined pattern appear on the sheet of the resin layer 1, and in this case as well, a cell-like pattern made up of the glossy part 1a and the critical part 1b can be made on the synthetic resin layer 1 in the same manner as in the case described above. Let it happen.

Further, a base material 3 such as a thermoplastic sheet, paper or cloth coated with an adhesive is laminated on the back side of the synthetic resin layer 1, and the elongated sheet 2 is deformed with a soft rubber roll. It may also be bonded to the base material 3 as shown by the imaginary lines in the figure.

Furthermore, although not shown in the figures, each of the pattern areas shown in FIGS. 1 and 2 may be formed by integrally attaching a protective sheet made of a transparent material to the upper surface side of each of the synthetic resin layers 1, that is, the wind pressure side. is also possible.

Before the surface of the synthetic resin R that has been rippled by the wind pressure of the blowing device 20 is smoothed, and the pigments P arranged in the vertical direction return to a stable horizontal state, Due to the viscosity of the resin R, the return of the pigment P to the horizontal state is delayed compared to the return of the rippled synthetic resin R to the horizontal state, so that the rippled surface of the synthetic resin R is restored to the horizontal state. In addition, this is done before the pigment P arranged vertically at the wave crest a returns to a stable horizontal state, and by doing this, the pigment P is fixed in the vertical state and the vertical state The pigment P forms a critical region 1b in the synthetic resin layer 1.
