Description

  The present invention provides a fiber laminate that is lightweight, not bulky, and has high heat retention, and a method for producing the fiber laminate.

Traditionally, birds such as ducks and geese have feathers (down feathers) and feathers (hereinafter referred to as “feathers”) that are lightweight, highly heat-insulating, and highly hygroscopic. Widely used for jackets.
In general, feather products such as clothing and bedding using feathers are filled with feathers between the front and back fabrics, but due to the nature of the feathers, they are partially distributed and not evenly distributed. A sufficient effect cannot be obtained for the entire product, which is not preferable in terms of design.
Therefore, a quilting process is performed in which the front and back fabrics are sewn at predetermined intervals to prevent the feathers from moving and being biased so that the feathers are evenly arranged throughout the product.
However, since the feathers are lightweight and each one is very fine, there is a problem in that it blows out from the gap between the fibers of the front and back fabrics, and from the needle hole that stitches the front and back fabrics together during quilting. Feather balloons also cause allergic dermatitis, bronchial asthma and rhinitis.
Therefore, in order to solve this problem, a high-density fabric is sandwiched between rollers and high pressure and heat are applied to crush and narrow the gap between the yarn and prevent the feathers from blowing out. Using a down proof fabric that fills the gap with resin and coats it, it prevents blowout of feathers.

However, fabrics that have undergone such processing have poor air permeability, poor hygroscopicity and divergence, and are hard and heavy due to the effects of coating agents. And the blowing of feathers from the needle holes at the stitched part of the back fabric cannot be prevented. Therefore, various techniques have been devised so far to prevent the feathers from blowing out.
As one of them, the feathers are stored in a pouch-shaped inner fabric called a downpack, and the downpack is placed in a space formed by sewing the front and back fabrics, so that the feathers can be blown out without becoming heavy. Methods for preventing this are widely used.
Further, for example, in Japanese Patent Application Laid-Open No. 2002-173815, “a plurality of medium fabrics are stacked and stitched at two places with two seams to form a filling portion having openings at both ends, and a front fabric is overlapped to form the two "Downwear that prevents blowing out feathers, characterized in that the center of the seam is sewed, then feathers are stuffed into the filling portion of the inner fabric, and the periphery of the fabric is stitched together with a lining" (patent) Reference 1).

This is a method for preventing the blowout of the blades from the seam by shifting the position of the seam of the middle fabric and the seam of the front fabric. "The material for the inner fabrics 1 and 2 may be any material such as synthetic fiber, natural fiber, or a blended or woven fabric of these, but it is preferable to use a fabric that has been down-proofed. In other words, it is impossible to completely prevent the feathers from being blown out except for the fabric that has been down-proofed.
In the case of using a fabric that has been subjected to a down proofing process, the hygroscopicity and the air permeability are poor as described above, and it is unavoidable that the weight increases as a whole.

Therefore, a technique for improving the problems of such downpacks is also disclosed.
In Japanese Patent No. 3274869, “a feather assembly comprising a feather assembly composed of a feather and a thermoplastic adhesive is bonded to the feather in a compressed state by the adhesive, and the bulk is recovered and used. A sheet and a method of using a feather sheet characterized by heating the feather sheet to a temperature equal to or higher than the melting temperature of the adhesive to recover the bulk ”(Patent Document 2).
Here, the feather sheet is used by interposing between the outer surface and the lining of clothes, etc. like the downpack, and the feather sheet temporarily compresses a bulky feather assembly, Is fixed in a state where it is sufficiently adhered, and when the sewing product is manufactured, stored, or transported, the compressed state is maintained, and after the sewing product is manufactured, the bulk is recovered to restore the original bulk. Can be worn.
In the above invention, since the thermoplastic adhesive is used, when the sewing product is manufactured and then heated to a temperature equal to or higher than the melting temperature of the adhesive, the adhesive is remelted, and the adhesive force is lowered to reduce the blades. Is removed, the blade returns to a bulky state containing a large amount of the original air, and then, when the temperature is lower than the melting temperature, the blade is bonded again in that state. Since the feathers are bonded to each other, the feathers are bonded to each other to prevent blowing out, and the weight is light. In addition, the feathers can be prevented from being scattered at the time of manufacture.

  However, according to the technique of Patent Document 2, the product must be heated to a temperature equal to or higher than the melting temperature of the adhesive after the product is manufactured. This is different from the sewing work process in the process of manufacturing the product, so it is a separate process and takes time to finish, which is wasteful in terms of time and cost.

JP 2002-173815 A Japanese Patent No. 3274869

By the way, feather products such as duvets and down jackets as described above are characterized by being bulky in order to make use of the texture of the feathers, and this bulkiness is the softness and lightness of feathers, heat retention and moisture retention. It can be said that it is a symbol.
However, due to the bulkiness that is characteristic of this feather product, there is a problem that it is difficult to handle because it is bulky and fluffy when worn, difficult to move, and takes up space such as when it is stored outside the winter or after taking off on the go there were.
In addition, as described above, when the downpack is inserted, the downpack fabric or the inside fabric is down-proofed, or a material that prevents the feathers from blowing out such as nonwoven fabric or nylon is used. Therefore, there was also a problem that the air permeability was not good and it was easy to get stuffy, and further heavy.
In recent years, in order to solve this problem, the amount of feathers has been reduced, the fabric to be down-proofed has been made extremely lightweight, the quilting process has been made by crimping instead of sewing, and the heat retention has been reduced, etc. , Feather products that are light, not bulky, and have high heat retention and moisture retention have been developed in various ways, but it is difficult to completely prevent the feathers from being blown out, and various processing has been costly It is an expensive product.

  Therefore, as a result of earnest research, the inventor of the present application has solved the problems of the above-mentioned various feather products, has the warmth of the feathers, is light and not bulky, has high air permeability and heat retention, and blows off and biases the feathers. Provided is a fiber laminate using new feathers having no wings.

It is lightweight with no blowout or bias from the seam, and it is warm with the feather fiber layer, and it does not require downpacking or downproofing, so it is breathable and comfortable ing.
And, since the fiber laminate is composed of about 0.2 mm to 1.5 mm in thickness of the feather fiber layer to be laminated and is bonded to the front fabric and the back fabric, it can be treated as if it were a single fabric, In commercialization, it can be cut and sewn as it is, and the outer fabric becomes the outer fabric of clothing and bedding, making it easy to manufacture, and there is no need for special processing or stuffing of feathers. The working environment can be maintained satisfactorily without feathers being scattered during sewing.
Furthermore, since the thickness of the feather fiber layer is configured to be as thin as 0.2 mm to 1.5 mm, clothing and bedding manufactured with a fiber laminate obtained by laminating the feather fiber layer is not bulky, It is easy to move, can be folded compactly, and is easy to store.
And since the materials of the front and back fabrics are not limited, any fabric such as stretch fabric, waterproof fabric, and highly absorbent fabric can be adopted, making it light and bulky while taking advantage of the features of the fabric Warm clothing and bedding can be provided.

  EMBODIMENT OF THE INVENTION The form for implementing the fiber laminated body concerning this invention and the manufacturing method of this fiber laminated body is demonstrated based on the figure of an Example.

FIG. 1 is a cross-sectional view illustrating a fiber laminate according to the present invention, and FIG. 2 is a perspective view illustrating the fiber laminate according to the present invention.
In the figure, 1 is a fiber laminate, 2 is a front fabric, 3 is a feather fiber layer, 4 is a back fabric, 5, 5 a and 5 b are adhesives.
In the embodiment of the fiber laminate shown in FIG. 1 and FIG. 2, the fiber laminate 1 is configured by laminating a front fabric 2, a feather fiber layer 3 and a back fabric 4 in order, and the feather fiber layer 3 is a front fabric. The fabric 2 and the back fabric 4 are bonded and integrated with adhesives 5a and 5b.
In this embodiment, the front fabric 2 and the back fabric 4 may be any natural fiber such as cotton, wool, hemp, etc., regenerated fiber such as rayon, synthetic fiber such as polyester, nylon, acrylic fiber, natural or synthetic leather, etc. You can use any material. Further, the front fabric 2 and the back fabric 4 may be the same material or different materials, and the material can be appropriately selected depending on what is manufactured.
The material is not limited because the feather 30 of the feather fiber layer 3 inserted between the front fabric 2 and the back fabric 4 is bonded to the front fabric 2 and the back fabric 4 by the adhesives 5a and 5b. This is because the large number of feathers 30 constituting the fiber layer 3 are also bonded to each other by the adhesives 5a and 5b, so that the feathers 30 do not blow out from the front fabric 2 and the back fabric 4 alone.
Therefore, the front fabric 2 and the back fabric 4 of the fiber laminate 1 according to the present invention are not particularly limited to a high-density material, and any material can be used regardless of the density and whether or not the down-proofing is performed. It can be used.
When manufacturing clothing and bedding, the front fabric 2 of the fiber laminate 1 can be used as the front fabric of the product. For example, when manufacturing clothing, the front fabric 2 and the back fabric 4 are elastic. When a certain material is selected, it is preferable that it is easy to take off and put on. When producing a bedding, it is preferable to use silk or cotton cloth for the front fabric 2 or the back fabric, which is light and soft to the touch.
As described above, the fiber laminate 1 according to the present invention is formed by bonding the front fabric 2, the feather fiber layer 3 and the back fabric 4 with an adhesive so as to be handled as if it were a single fabric. The feather fiber layer 3 and the back fabric 4 follow each other's movement and do not impair the stretchability, and different materials can be arbitrarily selected according to the application.

Further, the feather fiber layer 3 according to the present invention is composed of an aggregate of feathers 30. Here, “feathers” is a general term that includes both down (feathers) and feathers (feathers) of birds such as ducks and geese. Therefore, the feather fiber layer 3 may be composed only of the down, may be composed only of the feather, or may be mixed with the down and the feather.
Natural feathers are preferred 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.

In the fiber laminate 1 according to the present invention, the adhesives 5 a and 5 b used for bonding the feather fiber layer 3 to the front fabric 2 and the back fabric 4 are the front fabric 2 and the back fabric 4, and the feather fiber layer 3. There is no particular limitation as long as it can be adhered. Therefore, depending on the material of the front fabric 2 and the back fabric 4, hot melt adhesive, vinyl acetate resin adhesive, urethane resin adhesive, acrylic resin adhesive, silylated urethane resin adhesive, styrene butadiene It can be selected in consideration of the adhesion performance between materials such as a rubber adhesive, the presence or absence of a heating step in the manufacturing process, and the like.
In addition, when the front fabric 2 and the back fabric 4 are thin materials, when it is desired to reduce the amount of the adhesives 5a and 5b so as not to penetrate the material, a hot melt adhesive that can be melted by heat and bonded at high speed is suitable. .

And it is preferable to comprise the feather fiber layer 3 which comprises the fiber laminated body 1 concerning this invention so that thickness (alpha) of this layer may be set to about 0.2 mm-1.5 mm. This is because if the thickness is too thin, the amount of feathers is too small to ensure heat retention, and if it is 1.5 mm or more, the thickness of the fiber laminate 1 becomes thick and bulky, and there is no feeling of lightness. This is because manufacturing work such as sewing becomes difficult.
Therefore, more preferably, although depending on the material of the front fabric 2 and the back fabric 4, when the amount of feathers is adjusted so that the thickness α of the feather fiber layer 3 is about 0.4 to 0.8 mm, it is light and bulky. Therefore, it can be handled more like a piece of fabric, and can be manufactured and cut and sewed like a normal piece of fabric.

FIG. 3 is an enlarged photomicrograph for explanation of the fiber laminate according to the present invention.
In the fiber laminate 1 shown in the figure, a front fabric 2, a feather fiber layer 3, and a back fabric 4 are laminated in order from the top, and the feather fiber layer 3 is bonded and integrated to the front fabric 2 and the back fabric 4 with an adhesive. It is configured. The feather fiber layer 3 is configured by sandwiching a large amount of feathers, and is configured to be thinner than the thicknesses of the upper and lower front fabrics 2 and the back fabric 4. The feather fiber layer 3 in the figure is approximately 0.5 mm, and the total thickness of the fiber laminate 1 is approximately 2.5 mm.

Since the fiber laminate 1 according to the present invention can be handled as if it were one piece of fabric as described above, it can manufacture any clothing items such as jackets, trousers, skirts, shirts, cold protection inners and hats. The surface fabric 2 of the fiber laminate 1 can be used as the surface fabric of each product as it is.
Moreover, the fiber laminated body 1 concerning this invention can also be used for some clothing items. For example, it is possible to make a product with high design by combining the fiber laminate 1 only with the front body and the back body of the jacket and using an existing thin fabric for the sleeve.
Similarly, the fiber laminate 1 according to the present invention can also be used for bedding. Also for the bedding, the surface fabric 2 of the fiber laminate 1 can be used as it is as the surface fabric of each product.
And the bedding goods may also comprise the whole product by the fiber laminated body 1, and can also be set as the structure which uses the fiber laminated body 1 of this invention for some products.
Even when used for both clothing and bedding, if the fiber laminate 1 is configured by selecting at least the material of the front fabric 2 according to the product to be manufactured, it is light and warm and manufactured with a suitable material. Apparel and bedding can be manufactured.

Next, the manufacturing method of the fiber laminated body concerning this invention is demonstrated based on FIG.
As an example of the manufacturing method of the fiber laminated body 1 concerning this invention,
(1) a first step of placing a surface fabric with the side on which the feathers are stacked on the base as an upper surface;
(2) a second step of applying an adhesive to the outer fabric,
(3) a third step of laminating feathers on the outer fabric coated with the adhesive;
(4) Thereafter, a fourth step of manufacturing a laminated body by placing a backing fabric with the side where the feathers are laminated on the bottom surface;
(5) It consists of the 5th process which presses the said laminated body, dries and adheres and integrates.

In FIG. 4, the roll-shaped outer fabric 2 is set so that the side on which the feathers are laminated is the upper surface (first step), and the adhesive 5 is applied by the adhesive supply means (second step).
Application of the adhesive 5 by the adhesive supply means may be dot-like or line-like as shown in FIG. 2, and is applied so that the feathers 30 adhere to the entire surface of the outer fabric 2.
Further, as described above, a suitable adhesive 5 is appropriately used depending on the material of the front fabric 2 and the back fabric 4 as described above. In the case where the front fabric 2 and the back fabric 4 are thin fabrics, a small amount of thermoplastic adhesive 5 is suitable for finishing the surface side cleanly.

Then, in the second step, the feathers 30 supplied from the feather supply unit are laminated on the surface fabric 2 to which the adhesive 5 has been applied by the adhesive supply unit (third step).
As the feather supply means, a method that can be laminated on the upper surface of the outer fabric 2 without any unevenness is selected. For example, the feathers may be adsorbed by a method of naturally dropping the feathers on the applied adhesive 5 or by a method similar to electrostatic flocking by arranging electrodes.
After the third step, a laminated body is manufactured by aligning the back fabric 4 with the surface on which the feathers are laminated on the lower surface so as to sandwich the front fabric 2 and the feathers 30 (fourth step).
At that time, the adhesive 5 may be applied in advance to the surface of the back fabric 4 on which the feathers are laminated, and depending on the material of the back fabric 4, it is aligned with the front fabric 2 without applying the adhesive 5.
This is a type in which the adhesive 5 can be strongly adhered to both the front fabric 2 and the back fabric 4 depending on the type of the adhesive 5, and since the viscosity is low and easy to penetrate, the adhesive applied to the front fabric 2 Since the performance of the agent 5 can penetrate and adhere to the back fabric 4, the type that cures slowly, the fast type, etc., the adhesive 5 is applied only to the front fabric 2 according to these characteristics, or the front fabric 2 and the back fabric 4 The adhesive 5 may be applied to both sides of the film, or may be selected as appropriate.

Then, the laminate formed in the fourth step is pressed by a compression unit, then dried by a drying unit, wound up into a roll shape, and finished (fifth step). The pressing by the compression means is adjusted so that the feather fiber layer 3 has a predetermined thickness α.
In the figure, the operations of the press and the dryer are shown separately. However, when the thermoplastic adhesive 5 is used, compression (crimping), heating and drying are simultaneously performed by the hot press. If done, work efficiency can be increased.

  In addition, manufacture of the fiber laminated body of this invention is not limited to said Example, A various change can be added in the range which does not deviate from the meaning.

  In the fiber laminate according to the present invention, the front fabric, the feather fiber layer, and the back fabric are laminated in order, and the feather fiber layer is bonded and integrated with the front fabric and the back fabric with an adhesive, It can be used not only for down products such as down jackets, but also for general fabric products that require warmth, such as shirts, trousers, skirts, inners and hats, gloves, boot uppers and bags, duvets, blankets, sheets, and kotatsu. it can.
