[0009]

[Embodiment] As the fragrance used in the fragrance-forming slit yarn of the present invention, both natural fragrance and artificial fragrance can be used. Animal flavors are expensive and unsuitable, but plant flavors can use essential oils collected from plants. Synthetic fragrances are terpene compounds and their derivatives, which have a certain group that emits a fragrance and are said to be fragrance groups.The compounds are classified into hydrocarbons, alcohols, aldehydes, ketones, esters, phenol ethers, lactones, coumarins and quinones. Acid, etc. Among these synthetic fragrances, there are many examples of fragrances synthesized from essential oil components, those synthesized from tar-based raw materials, and fragrances that do not naturally exist in nature or have not yet been discovered.

The major natural essential oils are camphor oil, katssia oil, boudrose oil, clove oil, eucalyptus oil, cedar oil, sandalwood oil, daiwi gyo oil, ylang ylang oil, lemon oil, orange oil, bergamot oil, lavender oil. , Patchouli oil, citronella oil, lemongrass oil, vetiver oil, rose oil, geranium oil, peppermint oil, and pepper oil.

On the other hand, the main synthetic fragrances include vanillin, methyl salicylate, cinnamyl aldehyde, β-phenylethyl alcohol, oxytroneral, phenylacetaldehyde, piperonal and natural fragrances.
By mixing several or several tens of synthetic fragrances, the desired flower odor and other pleasant scents are created. It is also possible to add a small amount of eugenol as a harmony agent or a modulator to prevent monotony of aroma, or to add a trace amount of patchuri oil as a volatilization-holding agent for the purpose of preventing the prepared components from being dispersed separately. The limits of the pleasant and unpleasant odors of these fragrances are vague, and the definition of fragrance is incomplete, but the variety of fragrance is customarily determined. Since these fragrances have a short fragrance property in a single genus, a mixed fragrance in which several kinds of fragrances are mixed is preferable.

The perfume-containing paper used in the present invention is obtained by kneading the above-mentioned perfume or prepared perfume into a resin and applying the resin to Japanese paper, synthetic paper, non-woven fabric and the like.

In the present invention, since the paper contains the fragrance, it becomes possible to contain a large amount of the fragrance, and it is possible to improve the strong fragrance and the persistence of the fragrance period.

The adhesive in which the fragrance used in the present invention is kneaded is the above-mentioned fragrance or compounded fragrance kneaded in the adhesive.

In the present invention, a sustained-release fragrance obtained by adsorbing the fragrance or the prepared fragrance onto powder such as silicon dioxide, barium sulfate, calcium carbonate, magnesium carbonate to make the volatile component of the fragrance into a sustained release is also the above-mentioned fragrance or It is used in the same way as the compounded fragrance.

As the adhesive for kneading the fragrance or the prepared fragrance, a usual urethane resin-based, epoxy resin-based, polyester-based, acrylic resin-based or synthetic rubber-based adhesive is appropriately used.

As the plastic film used for the fragrance-forming slit yarn of the present invention, films such as polyamide, polyester, cellulosic acetate, polycarbonate, and fluororesin are used. Among them, the polycarbonate film and the polyester film are preferable because of their low aroma permeability. Among them, the film is used, but the polyester film is particularly preferably used because it is excellent in heat resistance, mechanical strength, chemical resistance and the like and has good processability.
It may be colored with a pigment dye in advance.

The thickness of the plastic film is 6-5.
It is selected from the range of 0 μm, more preferably 9 to 25 μm. The fragranced slit yarn of the present invention has the mechanical properties of the plastic film, and since the mechanical properties of the slit yarn obtained as it is determines the knitting property, weaving property, and texture, the thickness of the film is Considering the above, it is appropriately determined from the above range.

The metal vapor deposition layer used for the scented slit yarn of the present invention imparts particularly strong luster to the scented slit yarn of the present invention, and is provided on one side of the plastic film. The metal vapor deposition layer is made of a metal or a metal compound, and examples of the metal include gold, silver, aluminum, chromium, nickel, copper, palladium, lead, platinum, zinc and tin. Among these, gold, silver, platinum, palladium, etc. are used for high-grade products, and aluminum, silver, etc. are appropriately used when cost is important.

The metal vapor-deposited layer also includes nickel chromium,
It may be an alloy or compound such as a silver-copper alloy, brass, or zinc sulfide.

The metal vapor deposition layer may be formed of one kind of material, but may be formed of two or more kinds.

The metal vapor deposition layer has a uniform thickness, and the thickness is in the range of about 20 to 100 nm, and the range of 35 to 65 nm is particularly preferable.
When the thickness of the metal vapor deposition layer obtained by vapor deposition is less than the above range, the metallic luster is poor, which is not preferable. On the other hand, even if it exceeds the above range, the brilliance of the metal yarn does not increase, rather, cracks are likely to occur and the whole becomes rigid and lacks in texture, which is not preferable.

To form the metal vapor deposition layer, the metal or metal compound is used to form a vapor deposition film by a conventional vapor deposition method such as a resistance heating method, a high frequency induction heating method, and an electron beam heating method.

The fragrant slit thread of the present invention is obtained by micro-slitting the above-mentioned laminated body to a width of usually about 0.2 to 2 mm.

The transparent resin undercoat layer used for the fragranced slit thread of the present invention has a function of firmly adhering the plastic film and the metal vapor-deposited layer to each other, and a post-dyeing process of the fragranced slit thread of the present invention. And the durability of the processed wool product are provided on one side of the plastic film.

As the coating material for the transparent resin undercoat layer, 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, an acrylic resin or styrene. -Based resin, acrylic-styrene copolymer, polyvinyl butyral-based resin, polycarbonate-based resin, nitrocellulos-based resin, cellulose acetate-based resin, urethane-based resin, urea-based resin, melamine-based resin, urea melamine-based resin, epoxy-based resin, alkyd Resins, aminoalkyd resins, rosin-modified maleic acid resins and the like are preferably used alone or as a mixture,
A curable resin is particularly preferable.

The transparent resin undercoat layer coating composition is formed by applying an organic solvent solution or aqueous solution of the resin to a uniform thickness by a conventional coating method such as a gravure coating method or a spray coating method, and drying (thermosetting). Resin, electron beam curable resin, ultraviolet curable resin, etc. are cured) to form a transparent coating film.

The thickness of the transparent resin undercoat layer is usually 0.00
The thickness is in the range of 1 to 5 μm, preferably 0.005 to 2 μm. When the thickness of the transparent resin undercoat layer is less than the above range, the post-dyeing workability and the adhesiveness of the metal vapor deposition layer do not have functionality, which is not preferable. On the other hand, if the amount exceeds the above range, the whole becomes stiff and the weavability, knitting property and texture are lacking, which is not preferable.

The fragrant slit yarn of the present invention may be used as it is as a plain yarn, but it can also be dyed as a twisted yarn by twisting wool and a haori coat, a tasuki twist or the like to make a colored haori twist yarn, a tasuki twist yarn or the like. .
