[Industrial applications] The present invention is used for wallpaper, table cloth,
The present invention relates to a patterned nonwoven fabric having excellent design properties that can be used for calendars, pennants, and the like.

[0002]

2. Description of the Related Art Heretofore, fine embossing has been applied to wallpaper to generate light reflection, giving a three-dimensional texture with unevenness. However, since the emboss pattern is regular, only an artificial design can be obtained, and the wallpaper is not natural.

[0003] On the other hand, there is also known a wallpaper having a design property by printing or printing on a film or a base material of a wallpaper composed of a film and a base material. Because it is applied to the material, a three-dimensional wallpaper was not obtained.

[0004]

The present invention has been made to solve the above-mentioned drawbacks, and can be used for wallpaper, table cloth, calendar, pennant, etc., and is natural and rich in three-dimensional appearance. Another object of the present invention is to provide a patterned nonwoven fabric having excellent design properties.

[0005]

The present invention is a patterned non-woven fabric 1 in which a thin film 3 having a thickness of 10 μm or less is laminated and integrated along the surface of an entangled non-woven fabric, and a coating amount of an adhesive of 20 g / m ² or less. By laminating and unifying, the patterned nonwoven fabric 1 having more excellent design properties can be obtained.

[0006]

The patterned non-woven fabric 1 of the present invention is formed by laminating and integrating a thin film 3 having a thickness of 10 μm or less (hereinafter, referred to as a thin film 3) along the surface of the entangled non-woven fabric. The portion is integrated on the fiber, and the portion where the fiber 4 does not exist is buried in the space 5 between the fibers, so that an uneven pattern along the entangled state of the entangled nonwoven fabric 2 emerges. For this reason, the patterned nonwoven fabric 1 of the present invention has an excellent three-dimensional appearance, and furthermore, the uneven woven pattern of the entangled nonwoven fabric 2 appears at random, so that a nonwoven fabric with a very natural feeling and excellent design can be obtained.

Further, if the thin film 3 is laminated and integrated with an adhesive having a coating amount of 20 g / m ² or less, the voids 5 of the entangled nonwoven fabric 2 are not filled with the adhesive. And the patterned nonwoven fabric 1 having excellent design properties is obtained.

The entangled nonwoven fabric 2 of the present invention is a nonwoven fabric obtained by entanglement of a fiber web obtained by a card method, a spunbond method or an air lay method by a needle punch method, a water entanglement method or the like. Needle punching at a density of 20 to 800 needles / cm ² or water pressure of 10 to 15
Although a method of performing water entanglement at 0 kg / cm ² can be exemplified, a nonwoven fabric produced by any entanglement method may be used.

Since the entangled nonwoven fabric 2 becomes the basis of the pattern of the patterned nonwoven fabric 1, it is preferable that the ratio between the space 5 between the fibers and the portion where the fibers 4 exist is balanced. Means that the filling rate of the fiber 4 represented by the following formula is 2 to 4
0%, more preferably 9 to 20%. Fiber volume in a given volume Fiber filling rate (%) = ───────────── × 100

The fibers 4 constituting the entangled nonwoven fabric 2 of the present invention include regenerated fibers such as cellulose fibers, animal fibers such as silk and wool, semi-synthetic fibers such as acetate fibers, polyamide fibers, polyvinyl alcohol fibers, and poly (vinyl alcohol) fibers. Vinylidene chloride fiber, polyvinyl chloride fiber, polyester fiber, polyacrylonitrile fiber, polyethylene fiber, polypropylene fiber, polyurethane fiber, polyalkylene paraoxybenzoate fiber, polyclar fiber, phenol fiber, polyfluoroethylene fiber Synthetic fibers such as fibers can be exemplified, but are not limited thereto. In addition, when it is used as a wallpaper, it is more preferable to be flame retardant, and it is more preferable to mainly use polyvinyl chloride fiber, polyvinylidene chloride fiber, polyclar fiber, or the like. Further, in addition to the fiber composed of only a single component, a composite fiber composed of two or more components may be used.

[0011] Even if the entangled nonwoven fabric 2 of the present invention has a fiber filling ratio in the above-mentioned range, if the fibers 4 constituting the entangled nonwoven fabric 2 are fine and the voids 5 between the fibers are fine. The fineness of the fiber 4 is preferably 0.5 denier or more, since the pattern is hardly raised. Conversely, if the fiber 4 is thick, the pattern becomes coarse, so that it is preferably 30 denier or less.

In order to impart morphological stability to the patterned nonwoven fabric 1, an acrylic ester type, an ethylene-vinyl acetate copolymer type, a polyacetic acid Vinyl, polyvinyl chloride, synthetic rubber, urethane, polyester, etc.
In particular, a self-crosslinking synthetic resin or synthetic rubber may be provided as a binder. In this case, the voids 5 of the fibers 4 on the surface where the binder laminates and integrates the thin film 3 of the entangled nonwoven fabric 2
So as not to fill the entangled non-woven fabric.
It is preferred to keep the content to not more than% by weight.

Since the thin film 3 used in the present invention is as thin as 10 μm or less, the entangled state of the entangled nonwoven fabric 2 can be raised as it is. The thin film 3 may be a film, a vapor-deposited film, or a laminate of both a film and a vapor-deposited film. When both the film and the vapor-deposited film are laminated, the thickness of two layers is 10 μm or less.

As the film of the present invention, polyester,
Polyphenylene sulfide, polypropylene, polyethylene, vinyl chloride, polystyrene, polycarbonate, nylon, polyimide, polyurethane, ethylene-
Polymer films such as vinyl acetate copolymers, ethylene-ethyl-acrylate copolymers, and aluminum foils, metal foils such as copper foils can be exemplified.
Examples include gold and silver, but are not limited thereto.

The patterned nonwoven fabric 1 of the present invention comprises the entangled nonwoven fabric 2 and the thin film 3 as described above.
In this case, the pattern of the entangled non-woven fabric 2 emerges because the entangled non-woven fabric 2 is stacked and integrated along the surface of the entangled non-woven fabric instead of being simply integrated. This entangled nonwoven fabric 2 and thin film 3
When the thin film 3 is a vapor-deposited film, it may be deposited on the entangled nonwoven fabric 2 so as to have a thickness of 10 μm. Method, a dry lamination method, a hot melt lamination method, a thermal lamination method and the like. When an adhesive is used in addition to the entangled nonwoven fabric 2 and the thin film, the gap 5 between the fibers of the entangled nonwoven fabric 2 is determined by the adhesive.
20g / m ² so that the pattern is not buried
It is preferable to laminate and integrate with the following coating amount. It is more preferable to apply pressure after laminating the thin films 3 so that the thin films 3 are laminated and integrated along the surface of the entangled nonwoven fabric.

As described above, the patterned non-woven fabric 1 of the present invention is a non-woven fabric having an excellent three-dimensional appearance and a very natural design because the entangled state of the entangled non-woven fabric 2 emerges through the thin film 3. . In addition, if the print or printing is performed before or after lamination and integration on the entangled nonwoven fabric 2 or the film of the present invention, a pattern with a more three-dimensional effect is obtained. Furthermore,
If paper or the like is laminated and integrated on the surface opposite to the surface where the thin film 3 of the patterned nonwoven fabric 1 of the present invention is laminated and integrated, it is easier to handle, and if the flame-retardant paper is laminated and integrated, it can be suitably used as wallpaper. It will be.
