[0001] SELF CONTROL TYPE FABRIC HAVING ENHANCED BREATHABILITY [0002]

The present invention relates to a self-controlled fabric having improved breathability, and more particularly, to a self-controlling fabric having improved air permeability that dramatically increases the breathability due to structural deformation of the fabric as moisture is absorbed.

Generally, fabrics used for clothing are adhered to the skin when they absorb water and cause discomfort. Especially, sports apparel such as athletics and ball games is a garment that wears when taking exercise and activity intensely. Therefore, it is basically excellent in ventilation so as to take moisture and quick drying so as to keep the wearer's body comfortably from the outside environment .

The fabric used in conventional sports clothing is made of a material having excellent moisture-permeability or a material having excellent water-proof property as a surface material, and a certain air-permeation gap is formed between the skin and the outer surface of the user to prevent mutual contact. It is made by applying mesh fabric to lining.

However, such a fabric can not provide an effective ventilation gap between the outer surface and the wearer's skin during the use of the fabric, so that it is not possible to provide the initial desired air permeability when a large amount of secretion such as sweat is worn during wear, It is inconvenient for the wearer to wear the underwear while wearing the underwear in order to prevent it.

In recent years, a breathable waterproof fabric using a hydrophilic polyurethane that absorbs moisture generated and released to the outside and prevents external moisture from penetrating has been widely used in sports clothes or living clothes.

The moisture-permeable and waterproof fabric using the above-mentioned hydrophilic polyurethane is prepared by a laminating method, a dry method and a wet method. Japanese Patent Application Laid-open No. 3-213581 discloses a polyamino acid-based polylactic acid resin containing 0.1% or more of a powder of a reaction product of L- A moisture-permeable and waterproof fabric having excellent abrasion resistance, which is prepared by laminating a moisture permeable film made of urethane to a fabric, is disclosed in JP-A 2-47058, wherein a mixing ratio of a poly 2: 8, which is prepared by coating a resin composition prepared from an isocyanate compound, a hydrophobic organic solvent, a hydrophilic organic solvent and water on a sheet, drying the same, and then laminating the resin composition with a polyurethane adhesive. Japanese Patent Application Laid-Open No. 4-249142 discloses a coating for forming a microporous film on a circular cross section made of an antistatic fiber, wherein the inner layer of the coating resin contains a substance having a deodorizing property and the porosity of the coating film is 20 to 70% Japanese Unexamined Patent Application Publication No. 4-146275 discloses a deodorant antistatic breathable and waterproof fabric which comprises a porous moisture-permeable membrane made of a fluorine-modified polyurethane resin on the surface of a fiber and a porous moisture-permeable membrane formed of an emulsified polyurethane resin polymer Waterproof fabric is described.

The moisture-permeable and waterproof fabric using the hydrophilic polyurethane resin has drawbacks that moisture can not pass smoothly due to hydrophilicity of the polyurethane. In addition, when an organic solvent is used in the manufacturing process, the dyestuff may escape by the organic solvent to cause contamination.

In addition, since the hydrophilic polyurethane resin as described above has a limitation on the amount of moisture that can be permeated by the hydrophilic polyurethane resin, if a large amount of water is instantaneously generated, it can not be completely vaporized. .

Fig. 1 is a cross-sectional view of a magnetic control fabric according to the present invention. Fig. 1 (a) is a cross-sectional view showing a closed state of the opening and closing part in a dry state. Fig. 1 (b) is a cross-sectional view showing a state in which moisture is absorbed in the intermediate layer.

FIG. 2 is a perspective view showing a state of water absorption of a magnetic control fabric according to the present invention, FIG. 3 is a plan view showing various forms of opening and closing parts of a magnetic control fabric according to the present invention, FIG. It is the state of use.

As shown in FIG. 1, the permeability-improved magnetic control fabric of the present invention is a fabric having a multi-layered structure having different characteristics in the back layer 100, the intermediate layer 200, and the surface layer 300.

The backside layer 100 is a fabric having air holes 110 through which air can circulate freely. The fabric is made of natural fibers, synthetic fibers, regenerated fibers or the like according to the use purpose and the use place of the magnetic control fabric of the present invention, May be used as the fabric.

Also, the backside layer 100 may be manufactured by forming a vent hole in a general fabric, but a fabric of a mesh structure may be used to simplify the process.

The surface layer 300 is a layer formed with a plurality of open / close portions 330 having a connecting portion 310 connected to one end of the surface layer and cut into an arbitrary shape. The surface layer 300 may be formed by using natural fibers, synthetic fibers, regenerated fibers, The fabrics to be produced or fabrics produced by mixing the above-described fibers may all be used.

The middle layer 200 is cut in the same manner as the opening and closing part at the lower end of the opening and closing part 330 and the fibers extending in the longitudinal direction when the moisture is absorbed are longitudinally arranged in the connection part 310 so as to absorb moisture, ). The opening / closing part 330 is formed of the surface layer 300 and the intermediate layer 200 to control the exposure of the air holes 110 formed in the backside layer 100.

The intermediate layer 200 may be formed of a fabric using a fabric that is woven or knitted using fibers extending in the longitudinal direction when absorbing water, but it is preferable that the intermediate layer 200 absorbs moisture when the fabric is stretched in both directions It may be preferable to use a fabric which is stretched only in one direction since wrinkles may occur in the self-control fabric.

As shown in FIG. 1 (a), when the intermediate layer 200 is assembled with the surface layer and is in a dry state, the opening / closing part 330 is in a closed state, So that the ventilation hole 110 is exposed to the outside, and the air circulation outside and inside of the fabric is freely opened, thereby greatly improving air permeability.

The fibers extending in the longitudinal direction when absorbing moisture of the intermediate layer 200 may not be able to open and close the opening / closing part 300 when the elongation percentage in the longitudinal direction is less than 7% at the time of moisture absorption, so that it is preferable to use an elongation percentage of 7% or more. More preferably, fibers having an elongation percentage of 10% or more are used.

The fiber extending in the longitudinal direction when absorbing the moisture may be a copolymer. For example, a polyether ester-based copolymer composed of polyoxyethylene glycol and a hard segment composed of polybutylene terephthalate may be used as the soft segment.

As described above, the air permeability-improved magnetic control fabric according to the present invention, which is formed of the back layer 100, the intermediate layer 200, and the surface layer 300, is fabricated by the manufacturing process of each fabric, and the manufacturing process is variously performed . ≪ / RTI >

In order to form the opening and closing part 330, it is preferable that the surface layer and the intermediate layer are firstly laminated, the opening and closing part is formed, and then the laminate is formed with the back layer.

The surface layer 300 and the intermediate layer 200 can be made of a multi-layer fabric made of double-layered fabric and can be simplified by a pouring process, and the durability of the fabric can be improved.

In addition, since the intermediate layer 200 is elongated and opened in the opening / closing part 330, since the opening and closing part 330 may repeatedly operate, the shape stability of the opening and closing part 330 may be deteriorated. In this case, it is possible to improve the morphological stability of the opening / closing part by sewing with a pottery bar having elasticity.
