[0002]

2. Description of the Related Art Conventionally, as a gold / silver yarn, a slit yarn obtained by depositing a metal such as aluminum on a substrate such as a film and shredding is known. There is a twisted yarn such as a yarn obtained by winding an object around a core yarn such as a polyester filament. These conventionally known gold and silver yarns are frequently used in both Japanese and Western clothing due to their aesthetic characteristics such as glitter, but they can withstand the metal deposition process, slitting process, weaving process, scouring process, etc. The choice of base film, core yarn, etc. is limited, and the aesthetic features such as glitter are sufficient, but the texture such as lightness is not enough, and the aesthetic features such as glitter in the field of gold and silver yarns What satisfies the lightweight feeling at the same time has been demanded.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gold-silver thread which simultaneously satisfies aesthetic features such as glitter and lightness.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a slit yarn (A) obtained by chopping a laminated body obtained by depositing a metal on at least one side of a film, and a slit yarn (B) obtained by cutting paper and the like.
And gold and silver yarns.

[0005] A slit yarn (A) obtained by chopping a laminate obtained by depositing a metal on at least one surface of a film according to the present invention.
Examples of the film used include polyester films, polyamide films, cellophane, polyethylene films, etc., but polyester films, particularly polyethylene terephthalate-based films, are preferred from the viewpoint of thermal and mechanical properties. The thickness of these films is not particularly limited, either, but is preferably 12 μm or less, and more preferably 4 μm to 12 μm for the purpose of obtaining the lightweight feeling of the present invention.

As the metal, there are gold, silver, platinum, aluminum, nickel, chromium and the like.
Precious metals selected from silver and platinum are preferable, and precious metals to which other metals are added and contained are preferable as long as their properties such as glitter and corrosion resistance are not impaired. Means for depositing these noble metals on the film is not particularly limited, and there are known methods such as heat deposition, sputtering, ion plate ink, and the like, which are appropriately selected and used. Prior to these evaporations, the surface of the film may be subjected to a treatment such as a corona discharge treatment or a plasma treatment.

[0007] In the present invention, paper is a paper, foreign paper, synthetic paper, but nonwoven fabric is there not particularly limited to, is preferably a in from the gist of 60 g / m ² or less of the invention, more preferably 40 g / m ² The following are preferred. Among them, Japanese paper is particularly preferably used, and further scouring,
In order to sufficiently withstand post-processing such as dyeing, Japanese paper into which Manila hemp fibers are mixed at least 10% by weight is preferable. The slit yarn obtained by shredding these papers may be a flat slit yarn that has been shredded, but a twisted paper yarn lacking twist is also preferable in terms of strength.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A slit yarn (A) obtained by chopping a laminate obtained by vapor-depositing a metal on at least one surface of a film according to the present invention comprises a film as a substrate and a vapor-deposited layer obtained by vapor-depositing a noble metal. Although mainly, a known coloring layer, undercoat layer, and overcoat layer (protective layer) may be appropriately selected and used. In addition, a laminate obtained by vapor-deposition of a metal may be cut into at least one surface of the obtained laminate, that is, a film, or two laminates may be laminated and shredded. It is preferable to cut the two pieces of the base film together using an adhesive layer so that the base film is on the outer surface.

The overcoating (resin) layer suitably used in the present invention has a low mechanical strength and is susceptible to damage due to friction and the like. Since it is corroded by moisture, oxygen gas, carbon dioxide gas, sulfide gas, nitrogen oxide gas, etc., it is provided on the surface of the metal deposition layer. The thickness of the overcoat resin layer is usually in the range of 0.1 to 2 μm, preferably 0.5 to 1 μm.
The range is 5 μm. If the thickness of the overcoat resin layer is less than the above range, the metal deposition layer cannot be sufficiently protected from damage due to friction and the like. Further, corrosion due to moisture in the air, oxygen gas, carbon dioxide gas, sulfide gas, nitrogen oxide gas and the like cannot be prevented, which is not preferable. On the other hand, if it exceeds the above range, it takes a long time to apply and dry, and is not economically preferable, such as poor productivity.
In addition, the resulting gold and silver yarns are rigid as a whole and lack flexibility and supple texture, which is not preferable.

As the resin for forming the overcoat resin layer, for example, any of a thermoplastic resin, a thermosetting resin, an electron beam curable resin, and an ultraviolet curable resin can be used.
For example, acrylic resin, styrene resin, acrylic-styrene copolymer, vinyl chloride resin, vinyl acetate resin, vinyl chloride-vinyl acetate copolymer, polyvinyl butyral, polycarbonate, nitrocellulose, cellulose acetate, urethane resin, It is preferable to use urea-based resins, melamine-based resins, urea-melamine-based resins, epoxy-based resins, alkyd-based resins, aminoalkyd-based resins, and rosin-modified maleic acid resins alone or in mixtures. In addition, as the coating material for forming the overcoat resin layer, a material (colored layer) appropriately colored in advance with a coloring agent such as a dye (fluorescent dye or luminous dye) or a pigment (fluorescent pigment or luminous pigment) can be used. In this case, a gold-silver thread colored in addition to the color unique to the deposited metal can be obtained.

The overcoating resin layer is formed by applying an organic solvent solution or an aqueous solution of the resin for forming the overcoating resin layer by a usual coating method such as a gravure coating method, a spray coating method, a roll coating method, and a dipping method. A resin layer is formed on the metal vapor-deposited layer by applying to a suitable thickness and drying (curing in the case of a thermosetting resin, an electron beam curable resin, an ultraviolet curable resin, or the like) to form a laminate. Further, the overcoat resin layer may be colored with a coloring material such as a pigment. It is preferable that the overcoat resin layer contains a white pigment, for example, fine particles such as titanium oxide, calcium carbonate, and silicon oxide. Among them, titanium oxide is preferable, and by incorporating these titanium oxide fine particles, at least one surface of a transparent polyethylene phthalate film, a vapor-deposited film provided with a metal vapor-deposited layer, is a gold-silver thread characterized by being microslit. When the slit yarn is not wound and used when wound around a paper core, the polyethylene phthalate film is on the outside, and when it is visually controlled, the front and back are clearly preferable, and the evaporation film is also used. In the case of a gold-silver thread obtained by microslitting a laminated body bonded via an adhesive layer so that two films are on the outside, it is extremely easy to distinguish between the front and back of the film at the time of bonding.

The undercoat resin layer of the present invention, when a metal vapor deposition layer is provided on one side of a film such as a polyethylene phthalate film, improves the vapor deposition adhesion of the film when provided between the film and the metal vapor deposition layer. As the resin for forming the undercoat resin layer, any of various resins such as a thermoplastic resin, a thermosetting resin, an electron beam curable resin, and an ultraviolet curable resin can be used. For example, acrylic resin, nitrocellulose resin, urethane resin, melamine resin,
A single or a mixture of melamine-acrylic resin, urea melamine-based resin, epoxy-based resin, epoxy-isocyanate-based resin, aminoalkyd-based resin and the like can be preferably used. Particularly, a curable resin is preferable.

As the coating material for forming the undercoat resin layer, a coating material (colored layer) appropriately colored in advance with a coloring agent such as a dye (fluorescent dye, luminous dye) or a pigment (fluorescent pigment, luminous pigment) can be used. In this case, a gold-silver thread colored in addition to the color unique to the deposited metal is formed. The undercoat resin layer paint is applied to an organic solvent solution or an aqueous solution of the resin to a uniform thickness by a usual coating method such as a gravure coating method, a spray coating method, a roll coating method, and a dipping method, and then dried (heated). A curable resin, an electron beam curable resin, an ultraviolet curable resin, or the like is cured to form a coating film. The thickness of the undercoat resin layer is usually 0.05
２2 μm, preferably 0.1-1 μm. If the thickness of the resin coating is less than the above range, the post-processing resistance,
Since it hardly contributes to the improvement of noble metal deposition suitability and the like, there is no point in providing it, which is not preferable. On the other hand, if it exceeds the above range, it takes a long time for drying, and the productivity is inferior and the amount of resin used increases, which is not economically preferable.

The adhesive used for bonding the vapor-deposited film (laminate) in the gold-silver yarn of the present invention is not particularly limited. For example, urethane-based, ethylene-vinyl acetate-based, chlorinated polypropylene-based, and vinyl chloride-acetic acid are used. Solvent-based adhesives such as vinyl-based, acrylic-based, and acryl-vinyl chloride-vinyl acetate-based adhesives or emulsion-based adhesives can be used alone or in a blend. The formation of the adhesive layer is performed by applying and drying an organic solvent solution or an emulsion of the adhesive by a usual coating method such as a roll coating method, a gravure coating method, or a spray coating method at the time of forming the laminate. . Thereafter, the two are overlaid, heated and pressurized, and laminated to obtain a laminate of a laminate. The thickness of the adhesive layer is usually in the range of 0.5 to 3 μm, more preferably 0.8 to 2 μm.
It is appropriately selected from the range of μm. When the thickness of the adhesive layer (D) is less than 0.5 μm, sufficient adhesive strength is not obtained, which is not preferable. On the other hand, if it exceeds 3 μm, it takes time for drying and the amount of the adhesive used increases, which is not economically preferable.

The winding method (twisting method) of the slit yarn obtained by chopping the metal-deposited laminated body and the slit yarn obtained by shredding paper is a round twist, a bellows twist, a haori twist, a task twist, a brian star. There are twists, and co-twisting by drawing or twisting as one core yarn and the other as sheath yarn may be used. It is more preferred that the slit yarns alternately wind and appear on the surface.
