Description

The present invention relates to a laminated fabric for clothing, which is lightweight, not bulky, and has high heat retention, and a method for producing the same.

Traditionally, down (feathers) and feathers (feathers) of birds such as ducks and geese (hereinafter referred to as "feathers") are lightweight, have high heat retention, and have excellent moisture absorption and wicking properties, so they are ducks and down. Widely used for jackets.

However, bulky feather products have a problem that they are bulky and bloated when worn, and are difficult to move, and they take up a lot of space and are difficult to handle when stored outside of winter or when they are taken off.
In addition, in order to prevent feathers from blowing out, if a down pack filled with feathers is inserted between the front and back fabrics, the down pack fabric and inner fabric may be downproofed. Materials such as non-woven fabrics and nylon that prevent feathers from blowing out are often used, and there is also the problem that they are easily stuffy due to poor breathability and are heavy.
In recent years, in order to solve these problems, feather products that are light, not bulky, and have high heat retention and moisture retention have been developed by various methods such as reduction of the amount of feathers and weight reduction of the fabric itself. However, it is difficult to completely prevent feather blowout, and various processing costs money, making it an expensive product.

Therefore, the inventor of the present application has developed a laminated fabric for clothing using new feathers that are lightweight, not bulky, have high breathability and heat retention, and have no feather blowout or bias, while having the warmth unique to feathers. I applied for a patent.

FIG. 2 is a schematic explanatory view of a method for producing a laminated fabric for highly heat-retaining clothing according to the present invention. FIG. 3 is a schematic explanatory view of a method for producing a laminated fabric for highly heat-retaining clothing according to the present invention.

A mode for carrying out the laminated fabric for high heat-retaining clothing and the method for producing the laminated fabric for high heat-retaining clothing according to the present invention will be described with reference to the drawings of Examples.

FIG. 1 is a cross-sectional view for explaining the configuration of an embodiment of a laminated fabric for highly heat-retaining clothing according to the present invention.
(A) shows a state in which various materials are laminated for explanation, and (b) shows a laminated fabric for highly heat-retaining garments molded by heat pressing.
In the figure, 1 is a laminated fabric for highly heat-retaining clothing, 2 is a backing fabric, 3 is a first thermoplastic resin layer arranged in dots, and 4 is a second thermoplastic resin applied flat and evenly. Layer 5 is an airgel mixture layer, 6 is a spider web-like resin layer, 7 is a feather fiber layer, 8 is a front fabric, 8a is a front surface, and 8b is a back brushed structure provided on the back surface of the front fabric. is there.

In the embodiment of the laminated fabric for high heat-retaining garment shown in FIG. 1, the laminated fabric 1 for high heat-retaining garment is sequentially arranged in dots on the upper surface of the backing fabric 2 arranged in the lowest layer. A first thermoplastic resin layer 3, a second thermoplastic resin layer 4 uniformly applied flatly, an airgel mixture layer 5 composed of an airgel mixture, and a spider web-like resin formed in a spider web shape. The layer 6, the feather fiber layer 7 made of feathers, and the outer fabric 8 are laminated.

The thermoplastic resin layer laminated on the upper surface of the backing cloth 2 is formed by laminating a first thermoplastic resin layer 3 and a second thermoplastic resin layer 4.
The thermoplastic resin is evenly sprayed and arranged in dots on the first thermoplastic resin layer 3. The first thermoplastic resin layer 3 arranged in a dot shape melts when heat-pressed and enters the gap between the upper airgel mixture layer 5 and the spider web-shaped resin layer 6 to form a backing material 2. The feather fiber layer 7 and the outer fabric 8 are adhered and integrated. Examples of the resin constituting the first thermoplastic resin layer 3 include vinyl acetate resin type, polyvinyl acetal type, ethylene vinyl acetate resin type (EVA), vinyl chloride resin (PVC) type, and acrylic resin type (ACR). , Polyethylene (PA), Polyethylene (PE), Polyethylene terephthalate (PET), Polyethylene (PP), Polystyrene (PS), Cellulose, α-Olefin, Synthetic rubber (SR), etc. It can be selected in consideration of the adhesion performance between the second thermoplastic resin layer 4 and the aerogel mixture layer 5 to the aerogel mixture, the order of the heating steps in the manufacturing process, and the like.
The first thermoplastic resin layer 3 may be formed of the thermoplastic resin material alone or in combination of two or more.
In this example, a polyamide resin (PA) and a thermoplastic polyurethane elastomer resin (TPU) are used. These are excellent in adhesiveness and elasticity and are suitable.

A second thermoplastic resin layer 4 is laminated on the upper surface of the first thermoplastic resin layer 3 arranged in a dot shape.
The second thermoplastic resin layer 4 is uniformly and evenly laminated on the entire surface so as to have air permeability. The second thermoplastic resin layer 4 not only has an adhesive effect, but also has a windproof effect while being breathable because the resin material remaining after being heat-pressed and the water content of the solvent evaporates becomes like a film. It exerts its effect and helps to enhance the heat retention performance of the upper airgel mixture layer 5.
The thermoplastic resin material constituting the second thermoplastic resin layer 4 may be powdery, particulate, fibrous or liquid, but a powdery thermoplastic resin material is mixed with an organic solvent to obtain a second thermoplastic resin material. The second thermoplastic resin layer 4 can be easily formed by spraying and coating on the thermoplastic resin layer 3 of 1.
As described above, the highly heat-retaining laminated fabric 1 for clothing according to the present invention is formed by laminating not only the first thermoplastic resin layer 3 but also the second thermoplastic resin layer 4, so that the first thermoplastic resin is laminated. The layer 3 enhances the air permeability, the second thermoplastic resin layer 4 enhances the heat retention property, and the effect of the airgel mixture layer 5 is maximized.

The thermoplastic resin material constituting the second thermoplastic resin layer 4 is selected from the same resin group as the thermoplastic resin material constituting the first thermoplastic resin layer, and is particularly a thermoplastic polyurethane elastomer resin (TPU). ) Is well-adapted to the first thermoplastic resin layer 3, the thermoplastic polyurethane elastomer resin remaining after the solvent is melted after heating and pressing tends to form a film, is moderately breathable, and has adhesiveness and elasticity. Excellent and suitable.
Examples of the solvent for evenly dispersing the thermoplastic resin material of the second thermoplastic resin layer 4 include alcohols such as ethanol and isopropyl alcohol, ketones such as acetone, methyl ethyl ketone and cyclohexanone, ethyl acetate and butyl acetate. Examples thereof include esters, and it is preferable to select one having good dispersibility in compatibility with the thermoplastic resin material because water easily evaporates during hot pressing.

As described above, the thermoplastic resin layer laminated on the upper surface of the backing material 2 is composed of the first thermoplastic resin layer 3 and the second thermoplastic resin layer 4. By arranging the first thermoplastic resin layers 3 in dots, it is possible to apply the resin uniformly to a thickness corresponding to the first thermoplastic resin layer 3 and the second thermoplastic resin layer 4. It is a laminated fabric 1 for highly heat-retaining garments with extremely high breathability and heat retention.

An airgel mixture layer 5 is laminated on the upper surface of the second thermoplastic resin layer 4.
The airgel mixture layer 5 is composed of an airgel mixture in which an airgel and a synthetic resin are mixed.
Examples of the aerogel include silica aerogel, carbon aerogel, and alumina aerogel, and in the present invention, silica aerogel can be particularly preferably used.
As the shape of the material of the airgel forming the airgel mixture layer 5 in the highly heat-retaining laminated fabric for clothing according to the present invention, fine particles are preferably used. Further, a mixture in which airgel fine particles are contained in a synthetic resin foam is preferably used. The fine particles of airgel are very low-density solids, and are porous bodies prepared in a liquid, that is, gels are made into dry porous bodies by maintaining voids using supercritical drying. When aerogels are used, they are heated. Even after compression, it functions as if it forms a hollow layer. Also, airgel is an extremely lightweight solid.
Since the airgel has a lower thermal conductivity than the thermal conductivity of air, it has high heat insulating properties.

Conventionally, airgels with a high porosity are extremely fragile, easily crushed, tend to be crushed and easily generate dust, and when molded into a sheet, they are easily cracked or disintegrated, and their intended use is greatly restricted. ..
Therefore, in the present invention, the problem of airgel, which is considered to be difficult to use for the above-mentioned laminated fabric for clothing, is to use an airgel mixture in which an airgel and a synthetic resin foam are mixed for the airgel mixture layer 5. It has been resolved with.
Synthetic resin foams to be mixed with aerogels constituting the aerogel mixture include polypropylene (PP) foams, polyamide resin (PA) foams, thermoplastic polyurethane elastomer resins (TPU), polyolefin resin foams, and the like. , Polypropylene (PP) foam has excellent chemical stability, high heat resistance, high void ratio and flexibility, and is preferably used.

In the embodiment of the present invention, the airgel fine particles are mixed with the polypropylene (PP) foam and mixed and integrated to form the airgel mixture layer 5, thereby having high heat insulating properties as a whole and excessively inhibiting air permeability. It is responsible for the formation of the laminated fabric 1 for garments with high heat retention.
Further, the synthetic resin foam constituting the airgel mixture layer 5 becomes an adhesive when molded by heat pressing, enters the gaps of the feather fiber layer 7 laminated on the upper layer, and further forms the outer fabric 8 of the upper layer. It penetrates into the brushed tissue 8b on the back surface. Then, the back surface of the front fabric 8 and the feather fiber layer 7 are firmly adhered to each other.

The airgel mixture constituting the airgel mixture layer 5 may be further impregnated with fibers. By impregnating and blending the fibers, the strength of the fabric can be increased. Examples of the fiber include glass fiber and carbon fiber.
Further, in the airgel mixture layer 5, it is preferable to arrange the mixture of the airgel and the synthetic resin foam in a speckled shape or a dot shape, because it is possible to improve the heat retention and the air permeability.

In the highly heat-retaining laminated fabric 1 for clothing according to the present invention, a spider web-shaped resin layer 6 is laminated on the upper surface of the airgel mixture layer 5.
The spider web-shaped resin layer 6 is composed of a spider web-shaped resin.
The spider web-shaped resin layer 6 is composed of, for example, a material selected from thermoplastic polyolefin, polyester, and polyamide-based resins or fibers. These resin materials are dissolved and sprayed in a spider web shape. Then, when it is molded by heat pressing, the resin sprayed in the shape of a spider web melts and adheres intricately to the feathers laminated on the upper surface, preventing the feathers from floating, biasing, blowing out, and scattering. be able to.

Further, the spider web-shaped resin layer 6 has a large number of vents formed therein, and is unlikely to become hard even when adhered to the outer fabric 2, and the outer fabric 8 which is further laminated in the vents, for example, is further laminated. The brushed back brushed structure 8b on the back surface enters, and the thermoplastic resin that forms the spider web-shaped resin layer 6 melts and integrates with the brushed surface during heat pressing, and is easily compatible with the outer fabric 2 and the feather fiber layer 3. Since the feathers 70 are surely adhered to each other, it is possible to prevent the feathers 70 from coming off or scattering, and it is less likely that the feathers 70 will float unevenly.
As described above, in the laminated fabric 1 for highly heat-retaining garments in the present invention, the feathers 30 are blown out or removed by providing the spider web-shaped resin layer 5 between the backing fabric 2 and the feather fiber layer 3. Prevents splattering during processing into clothing, and constitutes a smooth fabric with higher heat retention.

A feather fiber layer 7 is laminated on the upper surface of the spider web-shaped resin layer 6.
The feather fiber layer 7 according to the present invention is composed of an aggregate of feathers 70. Here, "feather" is a general term that includes both down (feather) and feather (feather) of birds such as ducks and geese. Therefore, the feather fiber layer 7 may be composed of only down, only feathers, or a mixture of down and feathers.
Natural feathers are preferable because they are lightweight, warm and soft in texture, but the configuration of the present invention may use artificial feathers or artificial feathers of synthetic fibers called artificial feather cotton.

The outer fabric 8 is laminated on the upper surface of the feather fiber layer 7.
As the front fabric 9, a fabric having a brushed structure 8b on the back surface is used.
Since the feather fiber layer 7 and the spider web-shaped resin layer 6 constituting the highly heat-retaining laminated fabric 1 for clothing according to the present invention each have gaps and through holes, the feather fiber layer 7 is formed during heat pressing. The brushed back brushed tissue 8b in contact with the feather fiber layer 7 penetrates the gap of the feather fiber layer 7 and the ventilation hole of the spider web-shaped resin layer 6, and adheres to the aerogel mixture layer 5 underneath. .. Therefore, when the feather fiber layer 7 and the spider web-shaped resin layer 6 are formed by heat pressing, they are adhered as if they were in the gap between the raised back raised tissues 8b.
Then, the feather 70 of the feather fiber layer 7 and the resin of the spider web-shaped resin layer 6 enter into the gap between the brushes of the back brushed tissue 8b, and the aerogel mixture layer 5 and the lower layer of the airgel mixture layer 5 It is integrally adhered to the second thermoplastic resin layer 4 to form one heat insulating structure.
The heat-retaining structure is further mixed with the synthetic resin of the first thermoplastic resin layer 3 underneath, and is firmly adhered to and integrated with the backing material 2.

In this embodiment, the surface 8a and the back fabric 2 of the front fabric 8 are natural fibers such as cotton, wool and linen, recycled fibers such as rayon, synthetic fibers such as polyester, nylon and acrylic fibers, and natural or synthetic leather. Any material can be used.
Further, the surface 8a of the front fabric 8 and the back fabric 2 may be the same material or different materials, and the material can be appropriately selected depending on the material to be manufactured.
The material is not limited, as the feather 70 of the feather fiber layer 7 inserted between the front fabric 8 and the back fabric 2 penetrates into the raised tissue 8b on the back surface of the front fabric 8 to form a spider web-shaped resin layer 6. The resin material, the synthetic resin constituting the mixture of the aerogel mixture layer 5, and the resin such as the thermoplastic resin material of the thermoplastic resin layer (3, 4) under the resin material exert a function as an adhesive and are heated and pressed. This is because the respective resins enter between the feathers 70 and adhere the feathers 70 themselves to each other, so that the feathers 70 do not independently blow out from the front fabric 8 and the back fabric 2.
Therefore, the front fabric 8 and the back fabric 2 of the highly heat-retaining laminated fabric 1 for garments according to the present invention are not particularly limited to high-density materials, regardless of the density, and regardless of the presence or absence of down proof processing. , Any material can be used.

In addition, when manufacturing clothing and bedding, the front fabric 8 of the laminated fabric 1 for highly heat-retaining clothing can be used as it is as the front fabric of the product. For example, in the case of manufacturing clothing, the front fabric 8 and the back If a stretchable material is selected for the fabric 2, it is easy to put on and take off, and when manufacturing bedding, if silk or cotton cloth is used for the front fabric 8 and the back fabric 2, it is light and soft to the touch. ..
As described above, the highly heat-retaining laminated fabric 1 for garments according to the present invention is a thermoplastic resin, a spider web-like resin, and an aerogel mixture having an adhesive effect on the front fabric 8, the feather fiber layer 7, and the back fabric 2. The front fabric 8, the feather fiber layer 7, and the back fabric 2 follow each other's movements and do not hinder the elasticity, and are different because they are more firmly adhered and integrated and can be handled as if they were a single piece of fabric. The material can be arbitrarily selected according to the application.

The feather fiber layer 7 constituting the highly heat-retaining laminated fabric 1 for clothing according to the present invention is preferably configured so that the thickness α1 of the feather fiber layer 7 is about 0.05 to 2.0 mm. If it is too thin, the amount of feathers is too small to secure heat retention, and if it is 2.0 mm or more, the thickness of the laminated fabric 1 for high heat retention clothing becomes thick, bulky, and lightweight. This is because the feeling is lost and it becomes difficult to perform manufacturing operations such as cutting and sewing.
Therefore, more preferably, although it depends on the materials of the front fabric 8 and the back fabric 2, if the amount of feathers is adjusted so that the thickness α1 of the feather fiber layer 7 is about 0.4 to 0.8 mm, it is lightweight and bulky. It is suitable because it can be handled more like a single piece of fabric and can be cut, sewn, etc. like a normal single piece of fabric.

The thickness α1 means the thickness of the feather fiber layer 7 in the final form, and is the thickness of the portion excluding the front fabric 8 and the back fabric 2. The overall thickness α2 including the front fabric 8 and the back fabric 2 is preferably configured to be 0.5 to 4.0 mm. In particular, when the amount of resin in the spider web-shaped resin layer 6 and the airgel mixture layer 5 is adjusted so as to be about 0.8 to 2.5 mm and heat-pressed to form, as shown in FIG. 1 (b). Although it is extremely thin and light, it is possible to finish the highly heat-retaining laminated fabric 1 for clothing, which has high heat retention, as if it were a single piece of fabric.

As described above, the laminated fabric 1 for highly heat-retaining garments according to the present invention includes a backing fabric 2, a first thermoplastic resin layer 3 arranged in dots, and a second thermoplastic resin uniformly and evenly applied. Layer 4, aerogel mixture layer 5 composed of aerogel mixture, spider web-shaped resin layer 6 formed in a spider web shape, feather fiber layer 7 composed of feathers, and outer fabric 8 having a brushed structure 8b on the back surface. Are laminated in this order, and the thermoplastic resin layers 3 and 4, the aerogel mixture layer 5, and the spider web-shaped resin layer 6 each function as an adhesive, firmly holding the front fabric 8, the feather fiber layer 7, and the back fabric 2. It is composed by bonding and integrating.

The feather fiber layer 7 is formed by sandwiching a large amount of feathers, and is formed thinner than the thickness of the upper and lower front fabrics 8 and the back fabric 2. For example, when the total thickness of the highly heat-retaining laminated fabric 1 for clothing is about 2.5 cm, the feather fiber layer 7 is composed of about 0.5 to 0.8 mm.
Therefore, the laminated fabric 1 for highly heat-retaining clothing according to the present invention can be handled as if it were a single piece of fabric as described above, and therefore, jackets, trousers, skirts, shirts, cold protection inners, hats, etc. are optional. The outer fabric 8 of the laminated fabric 1 for highly heat-retaining garments can be used as it is as the outer fabric of each product.

Further, the laminated fabric 1 for highly heat-retaining clothing according to the present invention can also be used as a part of various clothing items. For example, the high heat-retaining laminated fabric 1 for clothing can be used only on the front and back of the jacket, and the sleeves can be combined with the existing thin fabric to obtain a product with high design.
Similarly, the laminated fabric 1 for highly heat-retaining clothing according to the present invention can also be used for bedding. As for bedding, the outer fabric 8 of the laminated fabric 1 for highly heat-retaining clothing can be used as it is as the outer fabric of each product.
As for the bedding product, the entire product may be composed of the laminated fabric 1 for high heat-retaining clothing, or the laminated fabric 1 for high heat-retaining clothing of the present invention may be used as a part of the product.
Regardless of whether it is used for clothing or bedding, if at least the material of the outer fabric 8 is selected according to the product to be manufactured to form the highly heat-retaining laminated fabric 1 for clothing, it is elastic and very warm. In addition, it is possible to manufacture light and moderately breathable clothing and bedding.

Next, a method for producing a laminated fabric for highly heat-retaining clothing according to the present invention will be described with reference to FIGS. 2 and 3.

By uniformly and flatly applying the second thermoplastic resin layer 4 to the upper surface on which the first thermoplastic resin layer 3 is sprayed in dots, the heat retention is enhanced and smooth while maintaining the air permeability. Consists of a highly heat-retaining laminated fabric 1 for garments that has elasticity and elasticity. Further, in order to apply the resin uniformly, it is preferable to use the second thermoplastic resin mixed with an organic solvent.

Then, the airgel mixture is uniformly and spotted on the upper surface of the second thermoplastic resin layer 4 by the resin supply means (fourth step). The arranged airgel mixture forms the airgel mixture layer 5 by a subsequent heating press step.
The airgel mixture layer 5 is composed of an airgel mixture in which an airgel and a synthetic resin foam are mixed. Since the synthetic resin foam is melted by a heating press at the time of molding to form an adhesive material, it is preferable to arrange the synthetic resin foam in a speckled or line shape in consideration of this.
In this embodiment, the airgel mixture layer 5 is composed of an airgel mixture in which a polypropylene (PP) foam is mixed with airgel fine particles and integrated.

Then, after arranging the airgel mixture, the resin material constituting the spider web-shaped resin layer 6 is sprayed on the upper surface thereof (fifth step).
In order to form the spider web-shaped resin layer 6, it may be placed on an aerogel mixture in which a resin sheet or resin tape formed in a spider web shape is arranged in advance, but it flexibly corresponds to the shape of the fabric. Therefore, it is preferable to spray the resin in the shape of a spider web on the upper surface of the aerogel mixture to form the resin layer 6 in the shape of a spider web.

Feathers 70 are laminated by the feather supply means on the upper surface of the spider web-shaped resin layer 6 laminated in the fifth step to form a feather fiber layer (sixth step).
As the feather supply means, a method that can be laminated as evenly as possible is selected. For example, the feathers may be adsorbed by a method of spontaneously dropping the feathers on the applied spider web-shaped resin, or by arranging electrodes and a method similar to electrostatic flocking.

After the feathers 70 are laminated to form the feather fiber layer 7 in the sixth step, the front fabric 8 is laminated on the upper surface of the feather fiber layer 3 and the thermoplastic resin material and the airgel mixture are laminated in this order on the back fabric 2. And the feathers 70 are arranged so as to be sandwiched between the backing material 2 and the feathers 70 to form a laminated body, and are laminated (7th step).
In the present invention, the front fabric 8 is provided with a back brushed structure 8b on the back surface. The brushed back brushed tissue 8b penetrates through the gaps of the lower feather 70 and the ventilation holes of the spider web-shaped resin, adheres to the synthetic resin foam of the airgel mixture layer 5, and the feather 70 of the feather fiber layer 7. It is sandwiched so that it is entwined, and the whole is integrated.

Then, the laminate formed in the seventh step is heated and pressed by a compression means (eighth step).
In this seventh step, the various thermoplastic resin materials constituting the laminate are heated and melted, mixed with each other, and entered into the gaps between the spider web-shaped resin layer 6 and the feather fiber layer 7, and each of them is formed. Adhere firmly.
In addition, the synthetic resin foam constituting the aerogel mixture layer 5 is also melted by heating, and the aerogel is adhered onto the backing material 2 via the synthetic resin foam and the thermoplastic resin material of the lower thermoplastic resin layer 4. At the same time, the aerogel enters and adheres together with the feathers 70 between the brushed back brushed tissues 8b on the back surface of the front fabric 8 via the resin of the synthetic resin foam or the spider web-shaped resin layer, and is integrated. High heat retention function to increase the heat retention of the entire laminated fabric for clothing.

After that, it is dried and finished by a drying means (finished product).
The press by the compression means is adjusted so that the feather fiber layer 7 has a predetermined thickness α1, and is finished to have a predetermined thickness α2 as a whole.
Although not shown, by carrying out the above series of manufacturing steps on the manufacturing line, the finished laminated fabric 1 for highly heat-retaining garments can be rolled up and finished.
The work by the press and the dryer does not have to be separate, and the work efficiency can be improved by simultaneously performing compression (crimping), heating and drying with a hot press or the like.

The production of the laminated fabric 1 for highly heat-retaining garments of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

In the laminated fabric for high heat retention garments according to the present invention, a front fabric, a feather fiber layer, and a back fabric are laminated in this order, and the feather fiber layer interposes various resin materials and an aerogel mixture in the front fabric and the back fabric. As it is glued and integrated, it has high heat retention and flexibility, so it has not only conventional feather products such as duvets and down jackets, but also shirts, trousers, skirts, inners, hats, gloves, boot uppers, bags, and duvets. , Blankets, sheets, quilts, and other cloth products that require heat retention can be used in general. In addition, due to its high heat retention, it can be suitably used for clothing and cold protection equipment for extremely cold regions.
