Description

  The present invention relates to a moisture-permeable and waterproof fabric used as a material for fashion clothing, sports clothing, bedding, and the like. More specifically, a thin, lightweight tricot knitted fabric having breathability and protective functions is moisture-permeable and waterproof. The present invention relates to a moisture-permeable and waterproof fabric based on a structure laminated on a member.

One of the functions required for materials used for various fashion clothes, sports clothes, and some beddings is a moisture-permeable and waterproof function.
The moisture permeable waterproof function is a function that allows water vapor to pass through without passing water such as rain.
For example, a mountain climbing jacket or the like is required to have a function of not allowing rain or dew from the outside to permeate and allowing perspiration in a water vapor state emitted from the body to permeate and release to the outside.

In recent years, moisture permeable and waterproof functions are also required for downwear using cotton batting, duvets, sleeping bags, and the like.
Many proposals have been made as materials that meet such required functions.
For example, as can be seen in Patent Document 1, a moisture permeable and waterproof fabric having a two-layer structure has been proposed for use in clothing or the like in which a fabric such as a polyester fabric is bonded to a microporous film.

  Patent Document 2 proposes a method for producing a moisture-permeable waterproof sheet having a two-layer structure in which a moisture-permeable resin extruded in a thin film shape is laminated on a woven fabric or a knitted fabric.

  Further, in Patent Document 3, a water structure in which a fiber structure composed of ultrafine fibers is laminated on a substrate such as a woven fabric or a knitted fabric, and a protective layer composed of a woven fabric, a knitted fabric, or a nonwoven fabric is provided on the surface of the fiber structure, Proposals have been made on moisture-permeable and waterproof fabrics having moisture permeability and stretchability.

  Patent Document 4 proposes a waterproof breathable fabric having a three-layer structure including a shell fabric as a front material, a tricot knitted fabric as a lining, and a waterproof film provided therebetween.

  Further, Patent Document 5 proposes a fabric intended to prevent blowing-out, which is used for downwear, a sleeping bag using down, a futon, and the like.

As described above, many proposals have been made for moisture-permeable and waterproof fabrics.
However, although these moisture-permeable and waterproof fabrics have a certain moisture-permeable and waterproof function, from the user's and manufacturer's standpoint, they are manufactured for sports clothing, fashion clothing, and some bedding. There is a required function that has not yet been solved for these materials.

For one thing, the functionality required of recent sports clothing and fashion clothing requires a thinner and lighter material function than ever before.
For example, downwear and windbreakers have been required to be moisture permeable and waterproof, thin and lightweight.
In addition, the material provided to produce a product such as clothing that satisfies these required functions is required to be easy to cut and sew as it is to obtain a product.
If a material that satisfies these requirements is provided, the manufacturing process can be simplified, the manufacturing time can be shortened, and the production cost can be reduced.

On the other hand, down is used for some bedding such as clothing and futons, but the materials provided for these manufactures, together with moisture permeable and waterproof functions, from the outer and lining, that is, from the side A function to prevent the down from coming out is required.
Further, futons and the like are also required to have a function of preventing the occurrence of shifting and biasing of batting and the like due to use.

There is a means to increase the density of the warp and weft of the woven fabric in order to prevent the pull-out of the down, but if the density is too high, a certain effect can be seen to prevent the pull-out, but the problem of reduced breathability or hard This causes problems such as uncomfortable use.
In addition, a partition is provided inside the futon to prevent down movement and bias, but the use of the futon also causes problems, such as being stiff due to the presence of the partition.

Looking at the prior art from the viewpoint of such requirements, for example, in the moisture-permeable waterproof fabric in Patent Document 1, a microporous film and a fabric such as a woven fabric are laminated and bonded together, and are inexpensive and dimensionally stable. It is supposed to provide a fabric that focuses on sex.
However, in this moisture-permeable and waterproof fabric, no consideration is given to the thinness and weight of the fabric and the simplification of the manufacturing process. In addition, it is impossible to produce sports clothing by cutting and sewing it as it is.

  Also, the moisture-permeable waterproof sheet shown in Patent Document 2 is structurally similar to that shown in Patent Document 1, and has a structure in which a moisture-permeable resin is laminated on a substrate such as a woven fabric, a knitted fabric, or a nonwoven fabric. It is hard to say that it has the required performance as an intermediate material.

Furthermore, the moisture-permeable and waterproof fabric shown in Patent Document 3 uses a woven fabric or a knitted fabric for the protective material to be seen as the outer material and the base material to be seen as the lining, and a moisture-permeable and waterproof fiber structure is provided therebetween, The product can be cut and sewn as it is to obtain a product.
However, it is difficult to say that the woven fabrics and knitted fabrics are designed with consideration for the functions required to be thin and light.

  Patent Document 4 also proposes a moisture permeable and waterproof fabric having a three-layer structure of the outer material, the moisture permeable waterproof membrane and the lining, but the tricot knitted fabric of the outer material and the lining resists severe impacts such as surfing. The strength to be obtained is claimed, and at least the technical means for reducing the weight and weight required recently is not proposed.

  Further, in Patent Document 5, a fabric is proposed as a material used for clothing using batting, and it seems that a certain effect has been obtained in preventing the slipping out of the down, etc. It is not made material.

As described above, in the prior art, certain proposals have been made regarding fabrics and sheets having a moisture-permeable and waterproof function and having a laminated structure and a bonded structure with a woven fabric or a knitted fabric.
However, these proposals provide technical means for today's demands for light weight and thinness, simplicity that can be used for cutting sewing as it is, and prevention of slip-out in down wear using batting. It was hard to say.

The present invention has been made against the background of the above circumstances.
That is, the object of the present invention is thin, lightweight, has functionality and design that should be used as a material for sports clothing, bedding, etc., and can be cut and sewn for commercialization. There is a place to provide breathable and waterproof fabrics.

  In order to solve the above problems, as a result of earnest and research, the inventors have a front member, a back member, and a moisture permeable waterproof member provided therebetween, and the front member and the back member, or one of them. In addition, the outer surface of the clothing, the functionality as the lining and the design backed by the functionality and a protective function for the moisture permeable waterproof member, and thin that does not interfere with the performance of the moisture permeable waterproof member, A lightweight, special tricot knitted fabric is used, and a moisture-permeable and waterproof fabric that can be used for cutting and sewing as it is is developed.

That is, the present invention includes (1), the table member and a back member provided between said surface member and a back member, the water is not through a waterproof member that moisture-permeable having a function of water vapor passing The front member, the back member, and the moisture permeable waterproof member are laminated with each other, and the front member and the back member or any one of them is a tricot knitted fabric formed of two series of knitting structures, and a tricot knitted fabric The ground is formed by a ground knitted portion knitted using synthetic fibers of 5 dtex to 12 dtex as knitting yarns, and a knitted knitted portion knitted by overlapping synthetic fibers of 5 dtex to 12 dtex on the ground knitting portions as knitting yarns. The part is a two-dimensional knitting structure, and the lap knitting part is a zigzag-shaped atlas knitting structure having a thread removal part in which only the ground knitting part exists, and the thread removal part forms a thin ground part, Except for the thread removal part, a thick part is formed and within a certain range. When it is folded, it resides in the moisture-permeable waterproof fabric that thin cloth part and a thick cloth part to the bent line is you are mixed.

That is, the present invention is ( 2 ) an atlas structure in which two series of knitting structures are formed in a zigzag shape as a target shape, and each atlas structure has a thread removal portion, and other than the yarn removal portion is correct. It exists in the moisture-permeable waterproof fabric of said (1) description which forms the quadrilateral part.

That is, according to the present invention, ( 3 ) a tricot knitted fabric formed of two series of knitted structures is formed of a net structure having a hole, and a linear reinforcing portion is formed in the center longitudinal direction of the hole. It exists in the moisture-permeable waterproof fabric as described in said (1).

That is, the present invention provides (4), the knitting yarn, above heat fusible polyurethane yarn made of polyurethane material and heat sealing material is used (1) consists in moisture-permeable waterproof fabric as claimed.

That is, the present invention resides in ( 5 ) the moisture-permeable and waterproof fabric described in (1) above, wherein split yarn is used for the knitting yarn.

That is, the present invention resides in ( 6 ) the moisture-permeable and waterproof fabric according to (1) above , wherein the tricot knitted fabric has a thickness of 0.05 mm to 0.15 mm and a basis weight of 13 g / m ² or less.

In addition, as long as the objective of this invention is followed, the structure which combined said (1)-( 6 ) suitably can also be employ | adopted.

In the moisture permeable waterproof fabric of the present invention, the tricot knitted fabric used for the front member and the back member or any one of them is a tricot knitted fabric using a synthetic fiber of 5 dtex to 12 dtex as a knitting yarn. The moisture permeable and waterproof fabric in which the fabric weight is 0.05 g to 0.15 mm and the basis weight is 13 g / m ² or less and the tricot knitted fabric is laminated is extremely thin and lightweight.

  And the tricot knitted fabric used for the moisture-permeable and waterproof fabric of the present invention is excellent in breathability because it is formed of extremely thin knitting yarns, and when this is laminated on the moisture-permeable and waterproof member, The surface can be protected without impairing the moisture-permeable and waterproof function.

  The tricot knitted fabric used for the moisture-permeable and waterproof fabric of the present invention is formed by two series of knitting structures, a ground knitted portion and a lap knitted portion knitted over the ground knitted portion, and the knitted knitted portion is a yarn. In the case of having the punched portion, only the ground knitted portion is present in the thread removing portion, so that the air permeability is improved and the moisture permeability function of the moisture permeable waterproof member is further exhibited.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings as necessary.

(First embodiment)
In the present embodiment, as shown in the explanatory view of FIG. 1 (lamination in the direction of the arrow), the moisture permeable structure constituted by the front member 11, the back member 13, and the moisture permeable waterproof member 12 provided therebetween. The waterproof fabric 1 will be described.
As the front member 11, a fabric such as a woven fabric, a tricot knitted fabric, or a circular knitted fabric can be used. In the present embodiment, a tricot knitted fabric for clothing is used.
A tricot knitted fabric T according to the present invention is used for the backing member 13.
An entrant film (trade name) is used for the moisture-permeable and waterproof member 12.

The tricot knitted fabric T of the backing member 11 is knitted using two pieces of cloth (Osa L1 and Osa L2) by a 28 gauge tricot machine W as shown in an explanatory view (partially omitted) of FIG.
Here, the gauge is the number of the knitting needles N arranged between 1 inch (2.54 cm), and the feed is a member equipped in the tricot machine W. Is controlled to form the structure of the tricot knitted fabric T.
Therefore, two lines of organization, that is, two pieces of cloth, are organized in two series.

In the present embodiment, the tricot knitted fabric T of the backing member 13 is composed of a ground knitted portion G with a texture C1 (2-0 / 1-3) and a texture with a texture L2 as shown in the organization chart of FIG. The overlap knitted portion D is formed of C2 (1-0 / 2-3 / 4-5 / 6-7 / 8-8-9 / 7-6 / 5-4 / 3-2).
The organization C1 is a double stitch.

In the second knitting, a knitting yarn is applied to two needles at a time to form a needle loop, so that the knitting principle shows that the knitting finished as shown in the structural entity diagram of FIG. 4 (partially indicated by bold lines). The ground needle loop NL is doubled (needle loops NL1, NL2), and the two adjacent needle loops NL1, NL1 are connected in the lateral direction by the sinker loop S1.
Similarly, the needle loops NL2 and NL2 are also connected by the sinker loop S2.
This is characterized in that a stable knitted fabric can be obtained with moderate elongation in the transverse direction.

The organization C2 is atlas knitting. Atlas knitting is a structure knitted in a zigzag shape as shown in FIG.
In the present embodiment, three knitting yarns are pulled out for every six knitting yarns to form the yarn removal portion F, so the overlap knitting portion D has a zigzag with a certain width by the six knitting yarns. It becomes a belt-like shape, and this is repeatedly formed in the transverse direction with the thread removal portion F in between.
Only the ground knitting portion G is present in the yarn removal portion F.
Therefore, the yarn withdrawal portion F has a characteristic that it is thin and has good air permeability as compared with the portion where the overlap knitting portion D exists.

In addition, since the overlap knitted portion D exists in a zigzag belt shape on the ground knitted portion G, even if the moisture-permeable and waterproof fabric is folded within a certain range during use, the knitted layer is always on the fold line. Since there is a portion, the overlap knitted portion D avoids contact with the ground knitted portion G from the outside, and the moisture-permeable waterproof member is not damaged.
The knitting yarn Y1 that forms the structure C1 and the knitting yarn Y2 that forms the structure C2 are both 8 dtex nylon yarns.

Usually, in a tricot knitting machine, a knitting yarn having a thickness corresponding to the gauge is used.
For example, in a 28 gauge tricot machine, the thickness of the knitting yarn suitable for the knitting, that is, the matching fineness is 70 to 100 dtex.
On the other hand, the thickness of the knitting yarns Y1 and Y2 used for knitting the back member 13 in the present embodiment is 8 dtex, which is extremely thin.
As a result, the needle loops NL slide with each other, and the knitted fabric form becomes unstable.
In order to prevent this problem, the film-shaped moisture-permeable waterproof member 12 is laminated to obtain form stability.

The formed backing member 13 has a basis weight of about 11 g / m ² and a thickness of about 0.07 mm, and becomes a thin and lightweight tricot knitted fabric T.
A moisture-permeable and waterproof member 12 is sandwiched between the back member 13 and the front member 11 of the tricot knitted fabric T and laminated with an adhesive to obtain the moisture-permeable and waterproof fabric 1.
As described above, since the backing member 13 is thin and lightweight, the moisture-permeable waterproof fabric 1 can be obtained which is significantly thinner and lighter than the thickness and weight of the three-layer moisture-permeable waterproof fabric manufactured by the prior art. .

For example, in the case of an entrant film (trade name), the moisture-permeable and waterproof member 12 itself is a thin material having a thickness of 20 μm, and is easily damaged by direct contact.
Therefore, it is required to protect this with another material, but the present tricot knitted fabric T has sufficient breathability and strength, and does not interfere with the moisture permeable waterproof performance of the moisture permeable waterproof member 12. The wet waterproof member 12 can be protected.

In the moisture permeable waterproof fabric 1, the tricot knitted fabric of the surface member 11 has strength, flexibility, texture, design, and the like as a surface material such as sports clothing.
And the tricot knitted fabric T of the backing member 13 has a function as a backing of sports clothing or the like.
The function of the moisture permeable waterproof fabric 1 as a lining is one of the functions of covering the moisture permeable waterproof member 12 without impairing the moisture permeable and waterproof performance, and one of the strength and texture as a lining. , Have a design.
Since this moisture-permeable and waterproof fabric 1 has the above-described features, sports clothing such as jellyfish and windbreakers can be constructed and manufactured using only this moisture-permeable and waterproof fabric 1. Enables simplification.

(Second Embodiment)
In the present embodiment, the tricot knitted fabric T of the backing member 13 has a texture C1 (5-6 / 5-4 / 5-6) as shown in the organization chart of FIG. 5 (partially indicated by a bold line). / 4-3 / 4-5 / 3-2 / 3-4 / 2-1 / 2-3 / 1-0 / 1-1-2 / 1-0 / 2-3 / 2- 1 / 3-4 / 3 -2 / 4-5 / 4-3), and tissue C2 (1-0 / 1-2 / 1-0 / 2-3 / 2- 1-3-4 / 3-2 / 4-5) / 4-3 / 5-5 / 5 / 5-4 / 5-6 / 4-3 / 4-5 / 3-2 / 3-4 / 2-1 / 2-3). The tissues C1 and C2 are symmetrical zigzag atlas tissues.
Each of them repeats 13 in 3 out as 1 repeat and passes through the knack, and the knitting position is appropriately adjusted and knitted.

The tricot knitted fabric T knitted in this way forms a zigzag-shaped thin ground portion U in which the thread withdrawal portions (3 out portions) of the lumps L1 and lumps L2 are symmetrical to each other, as shown in the schematic structure diagram of FIG. .
And the part surrounded by this thin ground part U forms the thick ground part A of a regular quadrilateral (a periphery is shown with a thick line for an understanding).
Even when the moisture-permeable and waterproof fabric 1 using the present tricot knitted fabric T as the backing member 13 is subjected to external friction and abrasion during use, the presence of the thick portion A is the friction from the outside to the thin portion. It is possible to prevent abrasion and the like, and the moisture-permeable and waterproof member 12 in the thin ground portion is not damaged.
Further, the regular quadrilateral thick ground portion A has an advantage of providing a diamond-patterned design effect.

Here, the tricot knitted fabric T in the first embodiment and the second embodiment is a tricot knitted fabric T to which an atlas structure and thread removal are applied from the viewpoint of the knitted structure.
One of or two of the two series of knitting structures forming the present tricot knitted fabric T has a thread withdrawal part F having a constant cycle, and the thread withdrawal part F is the structure C1 or the structure. The thin ground portion U is formed only by any one of C2, and the thick ground portion A is formed by the overlap of the structure C1 and the structure C2 except for the thin ground portion U, and the tricot knitted fabric T is bent in a certain length and in a certain range. At this time, since the thin ground portion U and the thick ground portion A are always mixed on the bent line, the moisture-permeable waterproof member 12 in the thin ground portion U is less likely to be damaged from the outside due to the thickness of the thick ground portion A. In other words, it has a feature of improving the durability of the moisture-permeable and waterproof fabric 1 itself.

(Third embodiment)
As described in the first embodiment, the thickness of the knitting yarns Y1 and Y2 used for knitting the back member 13 is 8 dtex and extremely thin.
As described above, since the fine knitting yarn is used as compared with the conforming fineness, the stitches are loose and are slidable with respect to each other.
Therefore, in the present embodiment, a heat-fusible polyurethane yarn is employed for the knitting yarn Y2 of the back member 13. The heat-sealable polyurethane yarn is a yarn in a form (not shown) in which a polyurethane material is positioned in the longitudinal direction of the center portion and is surrounded by the heat-sealable material.
In the present embodiment, Mobilon (trade name) is adopted.

In the heat-fusible polyurethane yarn, the heat-sealing material on the surface side is melted by the heat treatment after knitting, and the needle loops NL formed by the knitting yarns Y1 and Y2 are fused to each other so that the stitches slip each other. To prevent.
As a result, a stable tricot knitted fabric T with good mesh breathability can be formed, and unraveling from the cut end and the yarn breakage portion can be prevented.
Since the heat-fusible polyurethane yarn subjected to the heat treatment is fused while maintaining an appropriate flexibility, the elasticity inherent to the tricot knitted fabric is maintained without adversely affecting the texture of the knitted fabric.

In the present embodiment, a heat-fusible polyurethane yarn is employed as the knitting yarn Y2, but a heat-fusible polyurethane yarn can be used for either one of the knitting yarns Y1 and Y2, or both.
Other configurations are the same as those in the first embodiment.
Further, the heat-fusible polyurethane yarn used in the present embodiment is Mobilon (trade name), and 22 dtex is used.
Since the knitting is used in a stretched state, the knitting actually has a fineness of 15 dtex or less, and falls within the range of 5 to 15 dtex of the present invention.

(Fourth embodiment)
In the present embodiment, split yarn (unitika) is used for both or one of the knitting yarn Y1 and knitting yarn Y2 of the back member 13.
The split yarn is obtained by hardening several polyester yarns with nylon. By removing the nylon portion by post-processing, only the thin polyester yarn remains and a soft texture can be obtained.
By using split yarns for the knitting yarns Y1 and Y2, a tricot knitted fabric with a softer texture can be obtained. The split yarn used in the present embodiment is split into 7 filaments at 11 dtex.
Other configurations are the same as those of the first embodiment.
Of course, it is also possible to use the split fiber yarn and the heat-fusible polyurethane yarn used in the second embodiment in combination.

(Fifth embodiment)
In the present embodiment, the front member 11 and the back member 13 are both the back member 13 in the first embodiment, the back member 13 in the second embodiment, or the back member in the third embodiment. The configuration of the member 13 is the same.
By setting it as such a structure, the extremely thin and lightweight moisture-permeable waterproof fabric 1 can be obtained.
Use of the moisture permeable and waterproof fabric 1 for a side of a duvet, a partition wall, and the like leads to prevention of feathers from falling out and improvement in the use of the duvet.
In addition, it can be used in various fields as a lining for shoes or clothing, and the product quality can be improved.

(Sixth embodiment)
In the present embodiment, the structure of the tricot knitted fabric used for the backing member 13 is a net structure having holes.
As shown in the organization chart of FIG. 7 (partially indicated by bold lines), the knitting organization of the Osa L1 is the organization C1 (5-6 / 5-4 / 5-6 / 5). -4 / 5-6 / 5-5 / 5-6-6-5-4 / 3-2 / 1-0 / 1-1-2 / 1-0 / 1-1-2 / 1-0 / 1-2 / 1-0 / 1-2 / 3-4), and the knitting structure of OSA L2 is the structure C2 (1-0 / 1-2 / 1-0 / 1-2 / 1-1-0 / 1-2 / 1-0 / 1- 2 / 3-4 / 5-6 / 5-5 / 4-5-6 / 5-4 / 5-6 / 5-5 / 4-5-6 / 5-4 / 3-2).
The knitting yarns Y1 and Y2 are repeatedly passed through the knitting yarns Y1 and Y2 with 1 in 1 out and 5 in 1 out as one repeat, and the knitting positions are adjusted appropriately to perform knitting.

The tricot knitted fabric thus knitted is formed with a circular hole H as shown in the substantial explanatory view of FIG. The net-like tricot knitted fabric T1 having the linear reinforcing portion R is formed.
The linear reinforcing portion R is formed of a 2-weave knitted structure, and when the net-like tricot knitted fabric T1 is laminated on the film-like moisture-permeable waterproof member 12, moisture permeability that appears from the hole H is shown. The waterproof member 12 is reinforced.

Moreover, the linear reinforcement part R prevents the phenomenon in which the hole H of the net structure extends too much in the vertical direction, and enables the formation of a stable net-shaped tricot knitted fabric T1 having a circular hole H.
Compared to the conventional tricot knitted fabric with only the hole, the net-shaped tricot knitted fabric having the linear reinforcing portion R in the hole H has a good air permeability in addition to the good air permeability due to the hole H. Since there is a thin linear reinforcing portion R that does not interfere with the above, it is possible to protect the moisture-permeable and waterproof member 12 and to stabilize the form of the net-shaped tricot knitted fabric T1 itself.

The present invention has been described above by taking the embodiment thereof as an example. However, the present invention is not limited to the embodiment as long as the essence thereof is not changed, and various modifications are possible.
For example, it is not always necessary to have a three-layer structure in terms of its structure, and it may be a multilayer such as four layers, five layers, etc. with other members sandwiched depending on the application and purpose.
Further, depending on the application, the front member 11 formed of ultrafine fibers or the moisture permeable waterproof fabric 1 having a two-layer structure formed of the back member 13 and the moisture permeable waterproof member 12 may be used.
Further, the structure of the front member 11 and the back member 13 and the yarn type of the knitting yarn are not limited to the above-described embodiments, and various tissue development and yarn use are possible.

  The moisture permeable waterproof fabric 1 according to the present invention is used not only for bedding such as sports apparel, function apparel, and futon, but also for medical auxiliary materials such as bandages, clothing and diapers for nursing care, and even a bed. It can also be used as an auxiliary material for chairs and chairs.
