Description

[Detailed Description of the Invention] (a) Industrial Application Fields: Clothes, bags, bags, footwear, miscellaneous goods such as shoes, stationery such as covers and cases for albums, interior decorations such as wall coverings and furniture, etc. Concerning the materials used.

(b) Conventional technology Conventionally, fiber sheets and synthetic leather have been printed or surface-treated. There were some products, but none of them dared to change the physical properties of the sheet-like material to be processed and the processing material, and then additionally performed the following processing to bring out the characteristics of the product. .

(c) Problems to be solved by the invention Sheet-like materials such as paper or fibers, and plastic compositions and composite sheet-like materials based on these sheet-like materials (for example,
Vinyl leather, synthetic leather 1 artificial leather, etc. (hereinafter also referred to as artificial leathers) or composite sheet-like materials (hereinafter referred to as "artificial leathers"), or composite sheet-like materials (hereinafter referred to as "artificial leathers"), which are made of a layered film of a plastic composition.

The object that becomes the workpiece when some kind of addition is made is called a sheet-like object to be processed), and is subjected to coloring, printing, embossing, and in some cases, further rubbing, etc. but.

Although they were decorative, they were uniform and monotonous, lacked variation in appearance, and lacked a three-dimensional feel, a sense of porium, or a sense of nature.

2) Measures to solve the problem In order to give the sheet material to be processed a natural look that is not uniform and monotonous, processes such as bending, beating, rolling, or wrinkles are used instead of embossing. Ta.

In order to increase the effectiveness of such processing, before the processing, during or after the formation of the sheet-like object to be processed,
Any layer constituting the sheet material to be processed may be partially or unevenly impregnated, coated, or otherwise treated with a processing substance that has a different strain forming ability from the material of that layer. The material was processed by a method to partially change the density per unit volume, resulting in non-uniform physical properties.

Next, when processing distortions such as unevenness and wrinkles.

Or, after that, apply two-color processing to create various patterns.
I tried to emphasize the three-dimensional effect even more.

(c) Processing the inside or surface of any layer constituting the sheet-like object to be processed by partially or unevenly impregnating or coating with a processing substance. Due to this, the processed part will have a non-uniform structure with two parts that have different density, elongation, and tension.

Physical properties such as tearing, rupture, rigidity, and elasticity are different.

If this is subjected to full-formation processing such as unevenness and wrinkle processing, the resulting state will have very large changes in ribbing, roundness, + pattern, etc., compared to the case where two or more processings are not performed. Great diversification.

It gives a good three-dimensional effect.

By dyeing or coloring this during or after processing, the effect is further emphasized and a natural look of one tone of ``blurring'' or ``bleeding'' can be seen.

(to) Example Example 1 Weight: 1609/rye, thickness: about 90? yL-nonwoven fabric (e.g.

Spunbond LAEt161N manufactured by Toyobo ■ was impregnated with a 30% composition of acrylic emulsion belonging to the hard type, and the pickup was set to about 80%.

dry.

Next, a cloud pattern is printed using a brown or solvent-based printing ink using vinyl and acrylic as the vehicle, and then a skin layer is formed using an ink-dyed urethane composition using a transfer method. , an adhesive layer is formed as an intermediate layer to obtain synthetic leather.

Roughly, this is done by the wrinkling device (
The material is dyed by passing it through a kneading machine (hereinafter referred to as a massaging machine).

However, in FIG. 1 of the same publication, the original material for processing is transferred from the right side to the left side in normal rotation, but in the present invention, the raw material for processing is transferred from the right side to the left side so as to correspond to reverse rotation, and the raw material for processing is transferred from the right side to the left side, so that the raw material for processing is transferred from the right side to the left side. A driving roll or the like for assisting the transfer of the tension roller 1 shall be provided as appropriate, the AN heater shall be removed, and a tray for the colored liquid shall be provided under the mother heater.

In such a rolling machine, the raw material for processing is transferred downward from above the massaging section, the massaging section grips or holds the raw material for processing, and the material is gripped by creating slack between the gripping tools between at least two points. Rotate the ingredients and perform the kneading process as if you were kneading by hand.

Dye (in this case, dark brown il) is applied to the rubbed area.
A device is installed to spray a shower of dye).
Shower intermittently and rub while dyeing.

Then squeeze and dry.

For dyeing after the rolling process, pour the dyeing solution into the saucer at the bottom, away from the rolling area, and dye it in the same way as jigger dyeing.

When such processing is performed, the formation of wrinkles will differ depending on the printed pattern on the sheet-like material to be processed, depending on where there is more vehicle or where there is less vehicle.

Areas with a lot of vehicle have a high density, large stiffness, and fine wrinkles, and areas with a small amount of vehicle have a low density and are rough.
Rigidity is low, it is unpleasant to people, and penetration of the dye is large, and near the boundaries of density and structure, it appears as 5-color "bleeding" or "blurring", and the wrinkles are also linear density. The larger the value, the greater the change in unevenness and distortion.

Example 2 Weight: about 37+1/d, thickness: 0-34? Thickness about 0-57yL on AWL fine twill fabric? yL soft type vinyl sponge layer is formed, and on top of this, approximately 50g/- of an orange-based composition consisting of an acrylic vehicle is screen printed in a mosaic pattern and dried, and then a polyurethane adhesive is applied on top of this by 40g/- of an orange composition consisting of an acrylic vehicle. ~50 fi/d Coated as a base coat, and further coated with approximately 50 fi/d ink dyeable polyamide composition.
g/- Topcoat and dry.

After this is subjected to a rolling process as in Example 1, it is passed through a light brown acidic dye bath and dyed.

The printed part on the middle vinyl sponge layer is the non-printed part'), and becomes thicker and bulges, has greater rigidity, and has fewer wrinkles than the non-printed part, and the non-printed part has many fine wrinkles. form, and subtly affect the no(turn) after dyeing,
This will create a diverse group of trusts.

The above is an example of implementation, but raw materials that can be used include sheet-like materials in which fibers are intertwined in a layered manner2, for example, nonwoven fabrics, and fibers of the same or different types. Laminated products with different physical properties, composite sorted products of plastic compositions based on these fiber sorted products 1. For example, 9. Artificial leathers (vinyl leather, synthetic leather, 9. artificial leather, etc.), and plastic compositions. A single-layer or multilayer structure, such as a sheet of membrane-like materials, is used.

Surface treatment for these sheet-like objects to be processed.

Materials for processing such as printing, impregnation, and coating include various synthetic resins and colorants (including pigments, metal powders, inorganic powders, etc.) using similar synthetic resins as vehicles.
The usage form thereof may be a liquid one-foam composition liquid, a powder, a flake form, or the like.

These compositions can also be used as foaming compositions containing gas or blowing agents.

When processing raw materials with a processing material such as a sheet-like material for processing, even if the thickness or density is the same and the material has similar physical properties (for example, stiffness), Instead of uniformly processing sheet materials for
Since the part is partially processed, the physical properties will be different from the unprocessed part.

However, it will be more effective if the strain forming ability of the sheet material to be processed and that of the material for processing are opposite to each other, that is, the ability to form strain patterns is different.

For example, when the material is polyester, processing is performed using a substance such as ethylene/vinyl acetate, and when the material is acrylic, the main component is cafolystyrene.

Regarding the method of treating a sheet-like object to be processed with a processing substance, an arbitrary pattern such as a pattern can be added to any layer of the sheet-like object during the process of forming a sheet-like object or after forming the sheet. Spray screen printing, gravure coating, other coatings, impregnation or coating by means such as flow footing or press-fitting, drying, or embossing as appropriate to form thicker and thinner parts, processing Differences in the degree of adhesion of substances for use in a single sheet form dense and dense parts, and within these areas, stiffness, elongation, tensile strength, density, and other physical properties vary and are asymmetrical. can be formed in various ways.

When a processing substance is attached onto a film-like body (film or sheet) of a plastic composition, methods such as spray screen printing, gravure coating, flow coating, etc. can be used.

In the case of a composite sheet-like product, it is multi-layered using materials of the same type but different in density, rigidity, and other physical properties, or of different materials.

In order to give a natural pattern to the irregular sheet material to be processed as described above, it is necessary to bend it.

Measures such as bending, beating, squeezing, kneading, and wrinkles are taken.

These methods can be expected to have a relaxing effect and a wrinkle effect at the same time.

Further, since the sheet material to be processed has dense and dense parts, unevenness and wrinkles create complex dense and dense parts, giving rise to a three-dimensional or voluminous feel.

Regarding the formation of wrinkles, etc., the hardness and softness of the rigidity, the size of the wrinkles, and the density are not uniform depending on the physical properties of the sheet-like material to be processed and the degree of distortion formation.

As the next processing, coloring processing is performed during the distorted acid processing, and coloring processing may also be performed after such processing.2 A dye or pigment solution is used as the coloring processing liquid.

For coloring after distorted acid processing, various dyeing methods such as spray, zigzag, jigger, liquid flow, and high pressure dyeing methods can be used.

(Effects of the Invention) A wrinkled sheet material having a multilayer structure in which a processing substance is applied partially or non-uniformly to any of its layers, or whose strain forming ability is greatly different. Or, by using materials that are mutually contradictory, it was possible to make the sheet material to be processed even more uneven, differentiate the strain forming ability, and diversify the strain shaped acids. .

By further coloring the product in this state, a difference in the penetration level of each coloring liquid is created in parts, which greatly reduces the change in diffusion such as bleeding, diversifies the pattern, and increases the depth of one color tone. It gave a sense of three-dimensionality and had great decorative significance.
