Description

The present invention relates to fabrics and garments made therewith.

Traditionally, clothes have been required to have high designability. For this reason, fabrics used as materials for clothes are also required to have high designability. For example, fabrics are devised to improve their designability by various methods such as color scheme, partial design, expression of three-dimensional effect by unevenness, and the like.

Conventionally, as a method of imparting a three-dimensional effect to cloth used for clothes, a technique of using a foam layer on the cloth has been proposed. For example, Patent Literature 1 discloses a method of producing a voluminous fabric by bonding two pieces of fiber fabric together with an adhesive containing a foaming agent. Further, Patent Literature 2 discloses a fabric having protrusions formed on its surface by printing a resin containing a foaming agent on a fiber fabric in a predetermined pattern.

JP 2007-217841 A Japanese Patent Application Laid-Open No. 2008-238461

When two fiber fabrics are laminated as in the technique disclosed in Patent Document 1, if the fiber fabrics with the same front and back are laminated, the volume of the fabric is increased, and the fabric is given only one side, such as raising or glossing. In addition, by laminating two types of fiber fabrics of different colors and materials, the garment can be worn by turning the outer surface and the inner surface of the garment inside out depending on the mood or occasion. can be

The inventors of the present invention have proposed that the fabric obtained by laminating two fiber fabrics as described above is further provided with a convex portion made of a foam layer having an arbitrary design shape to enhance the design property. An attempt was made to combine the disclosed technique and the technique disclosed in Patent Document 2.

However, as in Patent Document 1, a method of adding a foaming agent to an adhesive, and as in Patent Document 2, a resin containing a foaming agent is printed on one side of a first fiber fabric in a predetermined pattern and then foamed. In the method of laminating the second fiber cloth after that, there is a problem that when the printed resin pattern is discontinuous and non-uniform, the adhesive strength is weak and peeling occurs.

On the other hand, when a resin containing a foaming agent is printed on one side of the first fiber fabric in a predetermined pattern, the second fiber fabric is laminated thereon, and then the foaming agent is foamed, the first fiber Since the foaming is performed in such a manner that the foaming agent and the resin for fixing the foaming agent enter into the fibers of the fabric, there is a problem that the pattern of the printed resin does not become a clear convex portion.

An object of the present invention is to solve such problems, and to provide a fabric having an excellent design and clothes manufactured using the fabric.

In order to solve the above problems, the fabric according to the present invention comprises a first fiber fabric, a resin layer, a foam layer having an arbitrary design shape, an adhesive layer, and a second fiber fabric. They are laminated in order, and the adhesive layer bonds the resin layer, the foam layer, and the second fiber fabric.

Moreover, in the fabric, the first fiber fabric and the second fiber fabric preferably have the same woven or knitted structure.

Moreover, in the fabric, the fineness of the finest thread forming the first fiber fabric and the fineness of the finest thread forming the second fiber fabric are both preferably 85 dtex or less.

Furthermore, the ratio of the fineness of the finest yarn constituting the first fiber cloth to the fineness of the finest yarn constituting the second textile fabric is 1.0:4.0 to 4.0:1. .0.

Furthermore, the ratio of the basis weight of the first fiber fabric to the basis weight of the second fiber fabric is preferably 1.0:3.0 to 3.0:1.0.

The present invention also includes clothing manufactured using the fabric.

According to the fabric according to the present invention, the resin layer and the foam layer laminated on the surface of the first fiber fabric and the second fiber fabric are bonded via the adhesive layer, so that it can withstand practical use. When the foaming agent in the foaming layer foams, the resin layer suppresses the penetration of the foaming agent and the resin (binder) that fixes the foaming agent into the fibers of the fiber fabric. The pattern of the foam layer having an arbitrary designed shape can be imparted to the fabric as distinct protrusions. Therefore, by manufacturing a garment using the fabric according to the present invention, it is possible to obtain a garment having a high convex portion with an arbitrary shape and an excellent design property.

A fabric according to an embodiment of the present invention will be described below. It should be noted that each of the embodiments described below is a preferred specific example of the present disclosure.

That is, in the fabric according to this embodiment, the resin layer, the foam layer and the adhesive layer are provided between the first fiber fabric and the second fiber fabric.

The first fiber fabric and the second fiber fabric are base materials of the fabric, and serve as the front and back sides of the fabric. That is, in the fabric according to the present embodiment, when the first fiber fabric is the front fiber fabric, the second fiber fabric is the back fiber fabric, and the first fiber fabric is the back fiber fabric In this case, the second fiber fabric is the front fiber fabric.

The first fiber fabric and the second fiber fabric used in the present embodiment are woven fabrics of plain weave, twill weave, satin weave, etc., or knitted fabrics of warp knitting, weft knitting (flat knitting or circular knitting), etc. However, it is preferable that the first fiber fabric and the second fiber fabric have the same woven or knitted structure so that the foam layer expands as evenly as possible on the front and back sides.

The fineness of the yarns used for the first fiber fabric and the second fiber fabric is not particularly limited, and both the warp and the weft may be 7 to 300 dtex, which is generally used for clothing, but the foam layer It is preferable that the thread is thin enough to be lifted and deformed as the foaming agent is foamed. By using such thin threads, the convex portions of the pattern of the foam layer formed in an arbitrary designed shape are likely to appear clearly, and are preferentially lifted when the foaming agent in the foam layer is foamed. From the above point of view, it is preferable that both the fineness of the thinnest thread forming the first fiber fabric and the fineness of the thinnest thread forming the second fiber fabric are 85 dtex or less.

In addition, if the fineness of the yarns of the front and back fiber fabrics (first fiber fabric, second fiber fabric) is relatively similar, the foam existing between the first fiber fabric and the second fiber fabric From the viewpoint that the layer tends to swell evenly toward the front side and the back side, the ratio of the fineness of the finest yarn that constitutes the first fiber cloth to the fineness of the finest yarn that constitutes the second fiber cloth is It is preferably 1.0:4.0 to 4.0:1.0, more preferably 1.0:2.5 to 2.5:1.0, and 1.0:2.0. It is more preferred that the ratio is ~2.0:1.0.

Similarly, if the resistance force of the fiber fabric on the front and back sides is relatively similar to the foaming force of the foaming agent in the foam layer, the foam layer tends to expand evenly toward the front side and the back side. The ratio of the basis weight (weight per unit area) of the first fiber fabric to the basis weight of the second fiber fabric is preferably 1.0:3.0 to 3.0:1.0. 0:2.5 to 2.5:1.0 is more preferred, and 1.0:1.5 to 1.5:1.0 is even more preferred.

Moreover, the first fiber fabric and the second fiber fabric may or may not be colored in advance. When coloring these fiber fabrics in advance, dyes such as disperse dyes, cationic dyes, acid dyes, direct dyes, reactive dyes, vat dyes, or sulfur dyes, or fluorescent brighteners, pigments, etc. can be colored using Furthermore, these fiber fabrics may be subjected to various treatments that are normally performed during coloring, such as a fix treatment using synthetic tannins, etc., which is performed when nylon is dyed using an acid dye. . The material used for coloring the first fiber fabric and the second fiber fabric is not limited to these materials, and an appropriate material may be selected according to the material of each fiber fabric. .

Moreover, the method of coloring the first fiber fabric and the second fiber fabric includes methods such as original dyeing, dip dyeing, and textile printing, and is not particularly limited.

In addition, water-repellent finishing, calendering, flame-retardant finishing, antistatic finishing, antibacterial and deodorizing finishing, antibacterial finishing, ultraviolet A shielding process, a process for improving light resistance, or a water-absorbing process, a moisture-absorbing process, or the like may be applied. From the viewpoint of suppressing the impregnation of the resin liquid, which will be described later, between the threads or fibers constituting the fiber fabric, it is preferable that at least the first fiber fabric is subjected to water-repellent treatment and/or calendering. . The second textile fabric may also be water-repellent and/or calendered.

Next, the resin layer used for the fabric according to this embodiment will be described. In this embodiment, the resin layer is laminated to the first fiber fabric.

The resin forming the resin layer is not particularly limited, but examples of the resin forming the resin layer include polyurethane, acrylic, polyester, silicone, polytetrafluoroethylene, nylon, and vinyl chloride. In this case, these resins may be used alone to form the resin layer, or two or more of these resins may be used in combination to form the resin layer.

The main function of the resin layer is to prevent the foaming agent and the resin (binder) for fixing the foaming agent from entering the gaps between the threads and/or between the fibers of the first fiber fabric. Therefore, the resin layer only needs to adhere to the extent that it fills the gaps between the threads and/or the fibers of the first fiber fabric, and the surface of the first fiber fabric is continuously coated. Alternatively, it may be a discontinuous material that adheres only to the concave portions on the surface of the first fiber fabric and fulfills the function of filling the gaps, and the convex portions on the surface are not covered.

Moreover, in order to impart windproofness and waterproofness to the fabric, the resin layer may have both windproofness and waterproofness.

Moreover, various additives may be added to the resin constituting the resin layer within the scope of the present invention. Examples of additives added to the resin include cross-linking agents such as isocyanate, oxazoline, epoxy, and carbodiimide; migration and sublimation inhibitors such as porous silica and activated carbon; moisture permeability imparting agents such as polyoxyalkylene glycol; Pigments, ultraviolet absorbers, antioxidants, deodorants, softeners, penetrants, emulsifiers, thickeners and the like.

In addition, in order to increase the height of the protrusions formed by the foam layer, not only the resin layer is laminated on the first fiber fabric, but also the resin layer is laminated on the side of the second fiber fabric facing the foam layer. may

Next, the foam layer used for the fabric according to this embodiment will be described. In the present embodiment, the foam layer may be composed of a foaming agent alone, but preferably contains a resin as a binder for fixing the foaming agent and the foaming agent to the fiber fabric. In other words, the foam layer may be composed only of a foaming agent or may contain a foam layer and a binder (resin or the like).

A known foaming agent can be used for the foaming agent used in the foam layer. The foaming agent used in the foam layer includes, for example, those that gasify due to phase change, and those that generate gas by reaction or thermal decomposition.

Moreover, it is preferable to use thermally expandable microcapsules as the foaming agent used in the foaming layer. This is because the microcapsules can be easily foamed at a high foaming ratio in the foaming step described below. Examples of microcapsules include those microencapsulated with an outer shell composed of a copolymer such as vinylidene chloride or acrylonitrile, a metal salt of a (meth)acrylic acid polymer, or a (meth)acrylic acid ester polymer. These microcapsules contain substances that gasify due to the above-mentioned phase change, substances that generate gas by reaction or thermal decomposition, and the like, and are expanded by heating or the like.

The foaming agent used in the foaming layer is preferably used in a form dispersed in a binder. Useful binders in this case include (meth)acrylic resins, polyurethanes, carboxymethyl cellulose, guar gum, sodium alginate, and the like. By using these resins, the foaming agent can be firmly fixed to the first fiber fabric.

A cross-linking agent may be added to the foam layer in order to more firmly fix the foam layer to the first fiber fabric. Useful crosslinkers include isocyanates, epoxies, dialdehydes, phenolic resins, melamine resins, imines, imidazolidinones, organic peroxides, allyl azides, diazirines, sulfur, and the like.

Furthermore, a surfactant may be added to increase the affinity between the foam layer and the first fiber fabric. Surfactants include anionic surfactants such as carboxylates, cationic surfactants such as quaternary ammonium salts, amphoteric surfactants such as betaine types, and alcohol ethoxylates. and nonionic surfactants.

In this embodiment, the foam layer has an arbitrary designed shape. In other words, the shape of the foam layer can be made into an arbitrary design shape according to the design to be expressed. As an example, the design of the foam layer includes a striped pattern in which linear patterns are repeated, a dot pattern in which relatively small polygons and circles are arranged regularly like a lattice, and geometric patterns such as arabesque and arabesque patterns. Examples include designs such as academic patterns, characters and logotypes, and characters and emblems. Moreover, the size of the design in the foam layer is also arbitrary. For example, the size of the design on the foam layer may be a one-point size applied to the left chest or upper arm, or the pattern may cover the entire garment made using the fabric obtained by the present invention. There may be.

The shape of the design in the foam layer is formed by foaming the foaming agent that constitutes the foam layer, and compared to the part where the foam layer does not exist, the thickness of the fabric is increased by the thickness of the foam layer. is represented by In addition, in the foam layers scattered as sea-island islands on the surface of the fabric, the thickness of the foam layers in the foam layer-existing portions forming the same islands is provided with a gradient or is changed stepwise, Alternatively, by changing the thickness between the foamed layers of the separate islands, it is possible to express a more complicated and three-dimensional design.

Further, in the fabric according to the present embodiment, the foam layer is used as an openwork pattern, and in order to improve the design, azo-based, anthraquinone-based, phthalocyanine-based, nitro-based, dioxane-based, titanium oxide, titanium oxide, Colorants such as zinc oxide, cobalt compounds, iron compounds, mica, and fluorescent pigments may be added.

Further, various additives may be added to the foam layer within the scope of the present invention. Additives added to the foam layer include porous silica, migratory sublimation inhibitors such as activated carbon, ultraviolet absorbers, antioxidants, deodorants, softeners, emulsifiers and thickeners.

The composition containing the foaming agent and the binder constituting the foaming layer preferably has a foaming agent:binder blending ratio of 1:2 to 20:1 in mass ratio. If the compounding ratio is within this range, a strong three-dimensional effect can be imparted to the fabric when the foaming agent is expanded.

Next, the adhesive layer used for the fabric according to this embodiment will be described. In this embodiment, the adhesive layer bonds the resin layer and foam layer to the second fiber fabric.

The adhesive constituting the adhesive layer is not particularly limited as long as it can firmly bond the resin layer and foam layer to the second fiber fabric. Useful adhesives include hot melt adhesives such as ethylene vinyl acetate, polyolefins, synthetic rubbers, polyamides, polyesters, polyurethanes, cyanoacrylates, urethane acrylates, acryloylmorpholines, epoxies, epoxy acrylates, vinyl esters, silicone resins, Adhesives such as liquid polyurethane and oxazoline adhesives can be used. When using an adhesive that causes a cross-linking reaction by physical or chemical means as the adhesive constituting the adhesive layer, heating, irradiation with active energy rays such as electron beams or ultraviolet rays, and mixing of the above-mentioned cross-linking agent and an appropriate catalyst are performed. Addition and means combining these may be used.

Further, various additives may be added to the adhesive layer within the scope of the present invention. Additives added to the adhesive layer include migration and sublimation inhibitors such as porous silica and activated carbon, ultraviolet absorbers, antioxidants, deodorants, softeners, emulsifiers and thickeners.

The adhesive layer is interposed between the resin layer, the foam layer, and the second fiber fabric in a point-like, linear, grid-like, or all-over-surface pattern, so that the resin layer, the foam layer, and the second fiber fabric are interposed. The shape of the adhesive layer is not particularly limited as long as the adhesive layer can be laminated by sticking together. At this time, since the resin layer and the foam layer are bonded to the second fiber fabric before the foaming agent in the foam layer is foamed, the two adherends are bonded together in a substantially flat state to widen the bonding area. and can increase the peel strength of the fabric.

The fabric obtained by laminating the second fiber fabric via the adhesive layer on the first fiber fabric having the resin layer and the foam layer is further subjected to irradiation with active energy rays, heating, wet heat, etc. By subjecting the foaming agent to a foaming process, a fabric having a foamed layer in which the foaming agent is foamed can be obtained, and a fabric having excellent design properties due to high convex portions having an arbitrary design shape can be obtained.

Next, a method for manufacturing the fabric according to this embodiment will be described. In addition, the fabric according to the present embodiment is not limited to that obtained by the manufacturing method described below.

First, a first fiber fabric and a second fiber fabric are prepared as base materials of the fabric. The first fiber fabric and the second fiber fabric are those described above, and if necessary, may be subjected to processing such as hot water washing, scouring, relaxation, and heat setting. These processes can be performed by known methods.

In addition, the first fiber fabric and the second fiber fabric may be dyed, printed, water-repellent, antistatic, water-absorbent, SR, antibacterial and deodorant, antibacterial, and antibacterial. Odor processing, ultraviolet shielding processing, flameproof processing, calender processing, etc. may be applied. In particular, from the viewpoint of suppressing the impregnation of the fiber cloth with the resin liquid used to form the resin layer described later, the first fiber cloth is preferably subjected to water-repellent finishing and/or calendering.

For example, when water-repellent finishing is applied to the first fiber fabric and the second fiber fabric, a fluorine-based, silicone-based, or paraffin-based water repellent agent is applied to the fiber fabric by a padding method, a spray method, or the like. It is dried at 40 to 140° C. for about 10 to 600 seconds, and if necessary, heat-treated at 130 to 200° C. for about 5 to 300 seconds.

Further, when the first fiber fabric and the second fiber fabric are calendered, the calendering may be performed by a known method, and is not particularly limited. As an example, calendering may be performed at room temperature to 200° C. and pressure (linear pressure) of about 100 to 350 kgf/cm.

Next, a resin layer is formed on the surface of the first fiber fabric. As a method for forming a resin layer on the first fiber cloth, there is a method in which the resin is applied by padding the first fiber cloth in a resin or a resin composition, or a method in which a prefabricated resin film is coated with an adhesive. Examples include a lamination method in which a resin or resin composition is applied to the surface of the first fiber fabric to laminate a resin layer directly on the surface of the first fiber fabric, and the like. be done. In order to reduce the weight of the fabric and soften the texture, it is preferable to use a lamination method or a coating method, more preferably a coating method, which allows a relatively small amount of resin to be adhered.

As a coating method, a known coating method can be used, and a knife coater, blade coater, gravure coater, reverse coater, extrusion coater, or the like can be used. Using these coating methods, the liquid monomer that reacts and hardens, heat melting, or the resin or resin composition that has been given fluidity by appropriately using a solvent or dispersion medium is applied to the surface of the first fiber fabric. The resin can be imparted to the first fiber fabric by applying to. At this time, if the first fiber fabric is impregnated with a large amount of the resin or resin composition applied to the first fiber fabric, the resin layer is not formed on the surface of the first fiber fabric, and a foam layer is formed. There is a risk that the function of preventing the foaming agent and binder from entering into the yarns and fibers of the first fiber fabric may not be sufficiently exhibited, and the amount of resin adhered is more than necessary to exhibit such an entry prevention function. There is a risk of increasing the weight of the fabric and hardening the texture, and the back surface (the outermost surface when it is made into clothes), which is the opposite side to the surface on which the resin or resin composition is applied. is impregnated, resulting in deterioration of appearance. In order to suppress resin impregnation, the first fiber fabric should be subjected to water-repellent finishing and/or calendering as described above.

After applying the resin or resin composition to the surface of the first fiber fabric, the resin is cured by heating or irradiation with active energy rays, the resin is solidified by cooling, or the solvent or dispersion medium is removed by drying. A hardened resin layer is formed on the surface of the first fiber fabric by performing wet coagulation or the like in which the resin is immersed in a solvent in which the resin is insoluble.

When a solvent or dispersion medium is used, depending on the solvent or dispersion medium, the resin and additives used, for example, after applying the resin solution to the surface of the first fiber fabric, at 40 to 140 ° C. It is dried for about 10 to 600 seconds, and if necessary, heat-treated at 130 to 200° C. for about 5 to 300 seconds. Thereby, a solidified resin layer can be formed on the surface of the first fiber fabric. In addition, drying may be omitted and drying and heat treatment may be performed simultaneously under the above heat treatment conditions.

Subsequently, a foam layer is laminated on the resin layer formed above. For example, the foaming agent or a composition containing a foaming agent and a binder is diluted with a solvent or dispersion medium if necessary, and applied to the surface of the resin layer in an arbitrary designed shape. Examples of the method of application include a transfer method using a gravure coater or the like, a printing method using a flat screen or a rotary screen, an inkjet method in which the ink is discharged from a nozzle, and a spray method using a spray. A composition containing a foaming agent or a foaming agent and a binder by a printing method is used from the viewpoint of facilitating the adjustment of the amount of the composition containing the foaming agent or the foaming agent and the binder and the ease of imparting an arbitrary pattern to the first fiber fabric. It is better to give things. In addition, the amount of the foaming agent to be applied per unit area may be appropriately adjusted in order to vary the thickness of the foamed layer after foaming and express a more complicated and three-dimensional design.

As will be described later, the resin layer, the foam layer, and the second fiber fabric are laminated together in a substantially flat state, and the adhesive sufficiently exerts its adhesive strength to sufficiently increase the peel strength of the fabric. Thus, the foaming agent in the foaming layer may be foamed at the same time as or after treatment such as irradiation with active energy rays, aging in a dry heat environment, moist heat environment, or autoclave, which will be described later.

In the case of dilution with a solvent or dispersion medium, drying is performed after applying a foaming agent or a composition containing a foaming agent and a binder. For example, by using a cylinder dryer, non-touch dryer, net dryer, loop steamer, oven, pin tenter, clip tenter, etc., which are generally used as dryers, drying for 0.5 to 5 minutes below the temperature at which the foaming agent foams. good.

Subsequently, an adhesive that will form an adhesive layer is applied to the surface of the adherend. The adhesive is appropriately diluted with a solvent or dispersion medium, if necessary, and applied to the surface of the resin layer and the foamed layer before foaming, or the bonding surface of the second fiber fabric. As a method for applying the adhesive, application using a knife coater, bar coater, slit coater, or the like, transfer using a gravure coater, or the like can be used. The adhesive may be applied in a shape such as a grid pattern or a solid pattern on the entire surface.

Subsequently, the surface on which the resin layer of the first fiber fabric prepared as described above and the foam layer before foaming are laminated, and the bonding surface of the second fiber fabric are attached to the surface to which the adhesive is applied. Paste through. A nip roll, a heated nip roll, or the like may be used for bonding.

In this way, the resin layer and the foam layer are bonded to the second fiber fabric before the foaming agent is foamed, so that the two adherends are bonded in a substantially flat state to increase the bonding area. It is possible to increase the peel strength of the fabric. Moreover, it is possible to prevent the foam layer from being crushed by the bonding pressure of a nip roll or the like during bonding.

When diluted with a solvent or dispersion medium, before bonding the resin layer and the foamed layer before foaming to the second fiber fabric with an adhesive, after bonding, or at both stages Dry. When the adhesive is applied on the resin layer and the foam layer, and the adhesive is dried after the bonding step, the temperature at which the foaming agent used is foamed or less is generally maintained. It may be dried for 0.5 to 5 minutes in an oven used as a machine.

After that, according to the type of adhesive used, it is subjected to treatments such as irradiation with active energy rays, aging in a dry heat environment, moist heat environment, or autoclave to promote the cross-linking reaction of the adhesive and the crystal orientation of the molecules. It is preferable to take measures so that the force can be sufficiently exerted, since the adhesive strength is increased and the peel strength between the first fiber fabric and the second fiber fabric is increased.

Subsequently, the second fiber fabric in which the first fiber fabric having the resin layer and the foam layer laminated is bonded together via the adhesive layer is subjected to processing such as irradiation with active energy rays and heating to produce a foaming agent. to foam. When a thermally expandable foaming agent is used, a cylinder dryer, a non-touch dryer, a net dryer, a loop steamer, an oven, a pin tenter, a clip tenter, etc., which are generally used as dryers, may be used. For emphasis, it is preferable to foam the foaming agent with as little tension as possible on the second fiber fabric in which the first fiber fabric laminated with the resin layer and the foam layer is bonded via the adhesive layer. The heat treatment temperature varies depending on the foaming temperature of the foaming agent, but is 140° C. to 220° C., more preferably 150° C. to 200° C., for 0.5 to 5 minutes. should be foamed. At this time, at the same time, the cross-linking reaction of the resin constituting the resin layer, the binder in the foam layer, and the adhesive in the adhesive layer may be promoted, and the crystal orientation of the adhesive molecules may be promoted.

As described above, the fabric according to the present embodiment can be manufactured. That is, it is possible to obtain a fabric having an excellent design property due to the tall protrusions having an arbitrary design shape.
