[Industrial application fields]
The present invention relates to a laminated yarn, a laminated body, and a textile product that have a safe and semi-permanent insecticidal / antifungal / sterilizing effect, can decompose and purify harmful substances, and can generate negative ions.
[0002]
[Prior art]
Conventionally, as fiber products having insect-proofing, mold-proofing and bactericidal effects, for example, fiber products kneaded with specific active ingredients during the production of raw fibers, and these active ingredients were attached in the dyeing process Along with textiles, etc., a metal layer capable of ion exchange is vapor-deposited on the synthetic resin film, and the synthetic resin films on which the metal layer is vapor-deposited are bonded so that the metal layer is on the inner side to produce a sandwich structure, A laminated yarn formed by cutting a sandwich-like structure into a thread and a fiber product in which a laminate formed by pulverizing the sandwich-like structure is attached to a raw yarn have been developed and used.
[0003]
On the other hand, negative ions are believed to have a relaxing effect on humans, and textile products that have adhered, mixed, and applied charcoal and tourmaline fine powders that generate negative ions have been developed and used. ]
[Problems to be solved by the invention]
However, these textile products have the following problems.
[0005]
Firstly, fiber products using laminated yarn and laminates are effective against bacteria, viruses and fungi that have been delayed in evolution even though they are a type of mold, but they have strong vitality such as black mold, red mold, and blue mold. There is a problem that it cannot be expected to completely suppress the growth of mosquitoes, and it cannot be expected to suppress the repellent effect of ticks, insects, and insects and the growth of large fungi and plankton.
[0006]
In addition, fiber products using charcoal or tourmaline have a problem that their functions cannot be maintained for a long period of time because charcoal, tourmaline, etc. fall off due to external stimuli such as washing.
[0007]
In addition, no textile product has been developed so far that has both insect and fungicidal and fungicidal effects and the ability to generate negative ions.
[0008]
Therefore, the present invention has an insecticidal, fungicidal, and bactericidal effect, can decompose and purify harmful substances, generate negative ions, and reduce these functions even when a stimulus such as washing or vibration is given. It is an object of the present invention to provide a laminated yarn, a laminate, and a fiber product that do not impair the tactile sensation, aesthetics, and functional feeling of the user.
[0009]
[Means for Solving the Problems]
That is, in the laminated yarn according to the present invention, the first metal layer is vapor-deposited on one surface of the synthetic resin film, and the second metal layer is made of a metal that is different from the metal constituting the first metal layer and has a potential difference. Is deposited on the first metal layer, and then the synthetic resin films on which the first and second metal layers are deposited are bonded together so that the second metal layer is on the inside. The body is manufactured, and the sandwich-like structure is cut into a thread shape to form antibacterial properties due to a potential difference generated between the first and second dissimilar metals.
[0010]
In addition, the laminate according to the present invention is a second metal layer made of a metal having a potential difference that is different from the metal constituting the first metal layer by vapor-depositing the first metal layer on one surface of the synthetic resin film.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0014]
FIG. 1 is a partially enlarged view of a T-shirt (textile product) A according to the present invention. As shown in FIG. Here, the yarn 1 is a yarn manufactured from natural or synthetic fibers, and the yarn 2 is a core yarn having a laminated yarn 3 described later as a core and a cotton fiber 4 as a sheath, as shown in FIG.
[0015]
FIG. 3 is a diagram schematically showing the structure of the laminated yarn 3. As shown in this figure, the laminated yarn 3 is composed of a first metal layer 3b and a second metal layer, which will be described later, by a synthetic resin film 3a. The laminated yarn 3 is manufactured by the following procedure.
[0016]
First, a metal is vapor-deposited on the synthetic resin film 3a by a vacuum vapor deposition method, an ion vapor deposition method, or the like to form a first metal layer 3b. Next, the 2nd metal layer 3c is vapor-deposited on the 1st metal layer 3b by the method similar to a 1st metal layer. Further, the synthetic resin films 3a on which the second metal layer 3c is vapor-deposited are bonded together with an adhesive so that the second metal layer 3c is on the inside, and the first metal layer 3b and the second metal layer A sandwich-like structure in which 3c is sandwiched between synthetic resin films 3a is manufactured. Finally, the laminated yarn 3 is completed by cutting the sandwich-like structure in the longitudinal direction. In addition, the width of the laminated yarn 3 is about 0.1 to 0.5 mm in consideration of economy and silkiness.
[0017]
Here, the synthetic resin film is a film made of polyester, polyamide, polyolefin or the like, and the thickness thereof is about 3 to 100 μm, and about 4 to 12 μm is particularly preferable.
[0018]
Moreover, as a metal which comprises the 1st metal layer 3b, metals, such as silver and copper, can be considered, but use of silver is optimal from a viewpoint of aesthetics, nobility, and safety especially. And the thickness of the 1st metal layer 3b is about 20-100 nm, and about 50-60 nm is preferable from the point of product cost.
[0019]
Further, as the metal constituting the second metal layer 3c, metals such as aluminum, nickel, and chromium are conceivable, but aluminum is optimal in consideration of the potential difference from the first metal layer and the price. . And the thickness of the 2nd metal layer 2b is about 20-100 nm, and about 50-60 nm is preferable from the point of product cost.
[0020]
Furthermore, examples of the adhesive include polyurethane adhesives, polyester adhesives, and acrylic adhesives. However, considering the safety of textile products, low formalin polyurethane adhesives and polyester adhesives are preferable.
[0021]
FIG. 4 is a partially enlarged view of a filter (fiber product) B according to the present invention. As shown in this figure, the fiber product B is obtained by attaching a laminate 6 to the surface of a nonwoven fabric made of yarn 5. is there. The yarn 5 is a yarn made of natural fiber or synthetic fiber. The nonwoven fabric may be a fabric having no thermoplasticity, but a thermoplastic fabric is preferable from the viewpoint of adhesiveness, and the yarn 5 is also preferably a thermoplastic.
[0022]
FIG. 5 is a diagram schematically showing the structure of the laminated body 6. As shown in this figure, the laminated body 6 includes a first resin layer 6b and a second metal layer 6c formed by a synthetic resin film 6a. It has a sandwich-like structure. An adhesive layer 6d is provided on one surface of the laminate 6.
[0023]
Such a laminate 6 is manufactured by manufacturing a sandwich-like structure by the same method as that for the laminate yarn 3, and coating one surface of the sandwich-like structure with a synthetic resin having a low melting point or a film made of a synthetic resin having a low melting point. Is made by bonding, cutting and crushing in both vertical and horizontal directions. In addition, as a cutting size of the laminated body 6, the substantially square whose one side is 0.1-0.5 mm is preferable. The thickness of the adhesive layer 6d is preferably as thin as possible, and a thickness of about 0.5 to 2 μm is optimal.
[0024]
The adhesive layer 6d is made of a synthetic resin having a melting point lower than that of the synthetic resin constituting the synthetic resin film 6a. As such a synthetic resin having a low melting point, polypropylene, polyurethane, acrylic, and polyester can be considered. However, what is necessary is just a thing whose melting | fusing point is 20-40 degreeC lower than the synthetic resin film 6a, and a polyester type is especially preferable.
[0025]
Specifically, such a laminate 6 can be attached to the nonwoven fabric by the following procedure. First, the laminated body 6 is mixed so that it may have a suitable mixing degree with water, a required amount is ejected from the flat nozzle to the surface of a nonwoven fabric, and the laminated body 6 is temporarily mounted uniformly. Next, after drying residual moisture from the nonwoven fabric, if hot pressing is applied, the adhesive layer 6d of the laminate 6 is melted to become an adhesive, and the laminate 6 is attached to the nonwoven fabric. And the laminated body 6 which was not affixed on a nonwoven fabric is collect | recovered by vacuum etc.
[0026]
For the same fabric, an adhesive is applied to a necessary portion of the nonwoven fabric, and the laminate without the adhesive layer 6d is sprinkled over the nonwoven fabric to cover the entire surface, and then the laminate without the adhesive layer 6d is heat-pressed from above. It can also be manufactured by thermocompression bonding and sucking the laminate 6 with vacuum or the like. However, the above-described method using the laminate 6 is more preferable in order to expose the cross section of the laminate as much as possible, prevent sliding of the laminate from the cloth as much as possible, and simplify the mounting method.
[0027]
Thus, since the side surfaces of the first metal layers 3a and 6a and the second metal layers 3b and 6b are exposed to the outside, they oxidize and chlorinate, but rub against each other with adjacent fibers, and the oxidized portion. May be removed, and even if it is not removed, it cannot be seen with the naked eye. Moreover, since parts other than the side surfaces of the first metal layers 3a and 3a and the second metal layers 3b and 3b are protected by the synthetic resin film 3a or 6a, they are not oxidized or salified. Therefore, even if washing is repeated or a bleaching agent is used, the effect of preventing insects, fungi, sterilization, and the effect of generating negative ions are not reduced.
[0028]
Next, the textile product according to the present invention is manufactured and subjected to various tests, and the present invention is described in more detail.
[0029]
(1) Manufacture of laminated yarn A first metal layer having a thickness of 50 nm was deposited on a 9 μm thick polyester film (manufactured by Toray Industries, Inc.) by vacuum evaporation. Next, a second metal layer made of aluminum and having a thickness of 50 nm was deposited on the pure silver metal layer by the same method. Furthermore, a polyester-type adhesive was used to bond the polyester films on which the metal layers were deposited so that the metal layers were on the inside, thereby producing a sandwich-like structure. Finally, the sandwich-like structure was cut into a width of 150 μm in the longitudinal direction to produce a laminated yarn.
[0030]
(2) Manufacture of underwear First, the laminated yarn produced in (1) was applied to a fine spinning and twisting machine to obtain a core yarn of cotton count 30 having the laminated yarn as a core and a cotton fiber as a sheath. Next, the core yarn is evenly arranged on 4 gauge, which is 1/6 of the total gauge of a 24 gauge knitting machine, and 100% cotton yarn of 30th is placed on the remaining 20 gauge to produce a tense knitted fabric. did. Then, after the bleached and dyed fabric of the manufactured woven fabric was cut and sewn, an underwear was obtained. In this underwear, about 3% of laminated yarn by weight is uniformly mixed in about 97% of cotton.
[0031]
(3) Manufacture of laminated body One surface of a sandwich-like structure manufactured by the same method as in (1) was coated with a polyester resin having a melting point of 130 ° C. at a thickness of 1 μm, and the coated sandwich-like structure was 0.15 mm. A laminate was produced by pulverizing to × 0.15 mm.
[0032]
(4) Manufacture of filter The laminate manufactured in (3) is mixed with water and diffused. From a nozzle having a flat mouth, it is laminated on a felt fabric of 100% polyester, thickness of about 8 mm, and weight of about 450 g / m ^2. After spraying evenly so that the weight of the body was 3% of the felt dough, it was applied to a dryer and pressed with a roll having a surface temperature of 160 ° C. at the outlet of the dryer. Finally, the laminate that did not adhere to the felt fabric was removed by vacuum to obtain a filter.
[0033]
(5) The underwear manufactured in the functional test (2) and the filter manufactured in (4) were confirmed to have insect-proofing, mold-proofing, bactericidal effects, and negative ion generation effects, and the deodorizing function was also realized. .
[0034]
Since underwear and filters manufactured by ordinary methods do not have such a function, these functions are due to the laminated yarn manufactured in (1) and the laminated body manufactured in (3). Conceivable. In addition, in order for an electric current to flow between different kinds of metals having a potential difference such as the first metal layer and the second metal layer constituting the laminated yarn or the laminated body, one of the metals is grounded or pure. A conductive state that is in contact with water that is not water is required, but these laminated yarns and laminated bodies are rarely grounded by grounding or the like. However, considering that mold and microorganisms grow in the underwear and filter, and the growth and activity of mites and fleas become active, moisture from sweat adhering to the underwear, air in the air adhering to the filter It can be considered that a conductive state is created by moisture coming from moisture, and that the effect of insect proofing, mold prevention, sterilization, and negative ion generation are produced by the mechanism of the battery.
[0035]
In addition, this invention is not limited to said embodiment and manufacture example, A various change can also be added within the technical scope described in the claim.
[0036]
For example, in the said embodiment, although 1st metal layers and 2nd metal layers were comprised with the same metal, respectively, these may be comprised from a different metal. Specifically, among the two synthetic resin films on which the metal layers constituting the laminated yarn or the laminated body are vapor-deposited, the first synthetic resin film has a first metal layer and a second metal layer, respectively silver, The second synthetic resin film may be made of aluminum, and the first metal layer and the second metal layer may be made of aluminum and silver, respectively. In this case, with the adhesive (insulator) in the center, the mechanism of the battery works for each synthetic resin film in the same manner as in the above embodiment, and the first synthetic resin film made of silver Since the mechanism of the capacitor works between the metal layer and the first metal layer made of aluminum of the second synthetic resin film, when the laminated yarn or the laminated body is in a non-conductive environment, charges are stored in the adhesive, If stored in a conductive environment, the stored charge is released.
[0037]
In the above embodiment, the underwear and the filter are exemplified as the textile products, but besides this, clothes such as underwear, socks, various shirts, belly wraps, nightclothes, sheets, duvet covers, blankets, pillow covers, etc. Daily bedding, towels, towels and other daily necessities, curtains, carpets, wallpaper, ceiling materials, flooring materials and the like.
[0038]
Further, in the above embodiment, the textile products A and B are textile products each made of a woven fabric and a nonwoven fabric, but in addition to this, a woven fabric manufactured by plain weave, twill weave, satin weave, and knit weave. Alternatively, a knitted fabric manufactured by tricot, raschel, miranese, flat knitting, circular knitting, or the like, or a knitted fabric manufactured by the Karl Mayer method or the like may be used.
[0039]
【The invention's effect】
The laminated yarn and laminated body according to the present invention have a sandwich structure in which two types of metal layers that generate a potential difference are sandwiched between synthetic resin films.
[0040]
For this reason, repeated washing of textile products containing these components, and the use of bleaching agents in these products will reduce the insect, fungicide, bactericidal and negative ion generation effects, and the metal layer will be blackened and laminated. The appearance of the yarn, the laminate, and the fiber product including these as a constituent element is not deteriorated.
[0041]
In addition, since the laminated yarn and the laminated body have flexibility due to the synthetic resin film and aesthetics based on the metallic luster due to the metal layer, the laminated yarn, the laminated body, and the textile products including these as a constituent element are sufficiently flexible. It has sex and aesthetics.
