Description

Textile wall paper and a method of manufacturing the same {A method for manufacturing a fabric wall and a fabric wall

The present invention relates to a fiber wallpaper and a method of manufacturing a fiber wallpaper, and more particularly, it is possible to fix a stretchable fiber through thermal bonding by inserting a hot melt in the form of a film between the fiber and the member as well as the interlayer bayer by the hot melt ( The present invention relates to a fiber wallpaper and a method of manufacturing the same, which do not interfere with the fiber through penetration into the fiber even if an adhesive or a pressure-sensitive adhesive of any chemical form is added to the lower layer of the member.

A fiber wallpaper is a structure in which a fabric (or fiber) is fixed on an upper layer of a member that provides a physical fixation force. The fiber wallpaper is excellent in heat retention and sound insulation and is usually used as a point wallpaper. The fiber wallpaper is a wallpaper in which fibers and members (usually paper) are bonded using a high viscosity adhesive. When the fiber wallpaper is attached to a wall or furniture, a separate adhesive or adhesive is used.

Because the fibers are served as weft and warp yarns, because of the elasticity of the length and width directions, it is impossible to connect the left and right designs with the fibers themselves.In general, the members are used to physically fix the fiber elasticity when used as wallpaper. In order to bond the paper and the fibers usually used as members, an aqueous adhesive or an adhesive (hereinafter adhesive) is applied to the upper surface of the paper, and then the fibers are adhered thereto to prepare a fiber wallpaper.

On the other hand, when the adhesive bonding the fibers and members is an oily component rather than an aqueous component, the adhesive may be adsorbed onto the fibers and the fibers may be discolored and expressed through the fibers. It is difficult to be used as wallpaper by curling or curling, so it was usually forced to use EVA-based water-based adhesives, and because of this, the adhesive strength between layers with fibers and paper is low, so that only fibers of a specific tissue are used as a fiber wallpaper or a fiber wallpaper. Was limited.

In addition, the fiber used in the fiber wallpaper is preferably processed in advance for the waterproof, antifouling, flame retardant, water-repellent function, etc., but the silicone material used for this special function further inhibits the adhesion to the paper member There was a problem. On the other hand, the conventional fiber wallpaper has a problem such that even if the adhesive is applied to the lower layer of the member and attached to the wall surface or furniture, the adhesive is adsorbed to the fiber through the paper and the fiber is contaminated.

Looking at the prior art documents related to fiber wallpaper, the following documents were examined. According to Korean Utility Model Publication No. 20-2009-000733 (Fiber wallpaper), an adhesive is applied to form a PE layer in order to fix fiber elasticity, but this prevents fiber contamination by liquid adhesive as in the prior art. Similarly, in Korean Patent Registration No. 867187 (functional fiber wallpaper and its manufacturing method) in which the coating liquid is applied to the fiber layer, problems such as fiber penetration by the coating liquid and the resulting fiber discoloration cannot be solved. In particular, in the latter case, since there is no use of a separate physical fixture, the continuous construction on the wall or furniture seems to be difficult.

SUMMARY OF THE INVENTION An object of the present invention is to propose a method for producing a fiber wallpaper into which a hot melt, which is a film in a solid form, is inserted in joining fibers and members. Although not limiting, the hot melt used in the present invention is in the form of a film based on polyurethane. The non-limiting hot melt applied in the present invention is in the form of a film based on a mixture of polyethylene and ethylene vinyl acetate. According to the present invention, as a member, not only paper but also nonwoven fabric, fiber, and plastic film may be applied, and polyester, cotton, hemp, silk, nylon, and acrylic may be applied. The hot melt in the solid form according to the present invention not only provides excellent adhesion between the fibers and the members, but also provides the advantage of preventing tension roller contamination and the like in a continuous process.

It is another object of the present invention to provide a fiber wallpaper in which hot melt is formed as a barrier layer by the manufacturing method. Adhesive and release paper may be added to the lower part of the fiber wallpaper laminated with the fibers, hot melts, and members. Thus, the advantage is that the adhesive cannot pass through the barrier layer and contaminate the fibers.

Another object of the present invention is to solve the difficulties caused by the fiber properties, that is, elasticity, contaminant, adhesiveness when applying the fiber to the wallpaper, thereby extending the scope of application of the fiber wallpaper furniture to eco-friendly and economical fiber wallpaper It is created to be practical for glass, iron and steel, and used as building interior materials.

The present invention discloses a fiber and member laminate structure and a method of manufacturing the same, which are thermally bonded to each other by using a hot melt between the fiber and the member to solve the problems of the prior art.

The hot melt provided in the structure not only has excellent adhesion between the fiber and the member, but also functions as a barrier against the interlayer fluid, thereby preventing any type of adhesive added to the lower part of the member from being transferred to the fiber to prevent fiber discoloration. .

Therefore, according to the present invention, by disposing a hot melt in the form of a film other than the usual adhesive between the fiber and the member and fixing it by heat fusion, the paper member, which was previously limited by the use of an adhesive in the form of an emulsion zone, is made of a non-paper nonwoven fabric, The member can be expanded to a plastic film, fiber, or the like. In addition, due to the hot melt barrier layer, the fiber adsorption of the adhesive used when bonding the fiber wallpaper to the wall or furniture can be suppressed to maintain fiber intrinsic color and texture, thereby increasing the added value of the fiber wallpaper.

Hereinafter, the present invention will be described in detail through examples.

Fibers that can be used in the present invention are fibers dyed by weft and warp yarns after the dyeing treatment according to the design using a fiber material yarn such as cotton, hemp, silk, polyester, nylon, acrylic. In the present invention, the member that can be heat-sealed with the fiber may be paper, nonwoven fabric, fiber, plastic. The hot melt of the solid film that can be applied to thermal fusion in the present invention is not limited, but is a hot melt film mainly composed of EVA and polyethylene mixed resins or polyurethane resins, which are commercially available.

Such raw materials constitute the fiber and member laminate structure by the following steps.

The first step is a step of stabilizing the fiber elasticity, the step of hot melt bonding at 130 ° C ~ 180 ° C by inserting a hot melt in the form of a film in the middle of the fiber and the member; The second step consists of a cooling fastening step for eliminating the weft and warp length of the fiber and the elasticity (twisting) in the width direction in the state of hot melt bonding the member attached by the fiber and the hot melt to manufacture the fiber and the member laminate. do. In addition to this, the step of applying an adhesive or adhesive to the fiber and member laminate structure in a third step; And a release paper attaching step as a fourth step.

In the first step, a hot melt film roll is preferably inserted between the woven fiber roll and the member roll, and thermally pressed at 130 ° C to 180 ° C simultaneously with lamination while maintaining the respective tensions. In the second step, the laminated structure is cooled to 10 ° C. to 30 ° C. while maintaining compression to achieve complete fusion. In this case, the compression time may vary depending on the laminated material. In the third step, a pressure-sensitive adhesive or an adhesive is applied to the bottom surface of the fiber and the member laminate structure formed in the second step, and in the fourth step, the release paper is bonded to the surface to which the pressure-sensitive adhesive or adhesive is applied, but the release agent is bonded. Instead, they can be directly bonded to walls, glass, metal plates, wood, and the like.

The fiber and member laminate structure according to the present invention formed by the first step and the second step was able to obtain complete adhesive force with the fiber and the member regardless of the member type, but using the conventional oily or aqueous adhesive When bonded with the fiber to form an incomplete laminate structure as follows. That is, in the case of using the oil-based adhesive is absorbed by the fiber and paper members, the adhesion is impossible, and when the aqueous EVA resin is coated on the paper and adhered to the fiber, it is impossible to adhere to the fiber when the viscosity of the coating agent is low. When the high viscosity coating was applied, the adhesion was unstable and soon peeled. On the other hand, when applied to the non-woven fabric, cotton or plastic film (LDPE) as a member using a conventional oil-based or water-based adhesive, the non-woven fabric and the surface member did not adhere due to contamination by the adhesive, the plastic film is weak adhesive strength It soon peeled off.

In addition, the fiber and the member laminate structure to which the adhesive and the release paper are added in the third and fourth steps are absorbed and displayed on the fiber due to the hot melt barrier layer formed even by applying an adhesive or an adhesive in the form of an aqueous or oily emulsion zone. While there is no phenomenon, the adhesive or adhesive can be applied to the member and then the release paper can be laminated to form a final product.However, the adhesive or the adhesive is applied to the member after preparing the fiber and the member (paper) laminated structure using a conventional technique, that is, an aqueous or oil-based adhesive. When the adhesive was directly applied, it was confirmed that there was no secondary workability due to the interlayer separation of the member (paper), adsorption to the fibers, and phenomena.

As described above, the hot melt is inserted between the fiber and the member according to the present invention and thermally melt-bonded, thereby fixing the elasticity of the length and the width direction coming from the woven weft of the fiber and the warp yarn with the physical force provided by the member, and as a hot melt barrier layer. By imparting the ability to suppress the expression of the fiber, even when the aqueous or oil-based adhesive or adhesive in the emulsion zone is applied, the color of the fiber is not changed and the multifunctionality can be realized. It can be bonded with metal plates, wood, and can convert wallpaper from one side of paper into fiber wallpaper. In addition, the fiber and member laminate structure can be used in the interior materials of ships, aviation, houses, furniture, railway vehicles in applications.
