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

1, the moisture permeable and waterproof fabric according to the first embodiment of the present invention comprises a fabric base material 200; A surface modification layer (201) formed on a bonding surface of the fabric substrate (200); A dot adhesion member 110 transferred to the surface modification layer 201 and adhered to one surface thereof; And a membrane 300 bonded to the other surface of the dot bonding member 110.

In the present invention, a physically chemically modified surface modification layer 201 is formed on the bonding surface of the fabric base material 200, the dot bonding material 110 is transferred to the surface modification layer 201, It is possible to improve adhesion between the fabric base material 200 and the membrane 300 by adhering the membrane 300 to the member 110.

Therefore, the moisture-permeable and waterproof fabric of the present invention can prevent delamination between the fabric base material 200 and the membrane 300 even if physical pressure is repeatedly applied by washing. Even if delamination occurs between the fabric base material 200 and the membrane 300, most of the dot bonding material 110 maintains the adhesive force. Therefore, there is a fear that the function of the membrane 300 due to delamination between layers may be lost There is no.

The adhesive surface of the fabric substrate 200 is subjected to a physical surface modification and a chemical surface modification in which a polar functional group is generated so that the surface of the fabric substrate 200 is subjected to surface modification with excellent wettability, Layer is formed and the adhesion of the dot bonding member 110 is improved. Here, physical surface modification is a modification of scratches, irregularities, or the like formed on the bonding surface of the fabric substrate during the surface modification process. This physical surface modification increases the bonding area of the dot bonding member 110 The adhesive strength can be increased.

In addition, chemical surface modification can be accomplished in a variety of ways, for example surface modification using corona discharge can be used. In the surface modification process using the corona discharge, high-energy electrons or ions are caused to collide with the surface of the fabric substrate 200 to generate polar functional groups along with physical surface modification according to the corona discharge, Or ion can be formed. Ozone, oxygen, nitrogen, water and the like may be reacted with these to introduce a polar functional group such as a carbonyl group, a carboxyl group, a hydroxyl group or a cyano group, and the surface may be chemically modified. When modified chemically in this way, adhesiveness, printability, coating properties, deposition characteristics, and the like due to the improvement in hydrophilicity can be improved.

The dot bonding member 110 is a plurality of circular or polygonal dot-shaped adhesives arranged in a matrix-like pattern spaced apart from each other regularly. The dot adhesion member 110 is first transferred to the transfer assisting film 100 so as to be transferred to the surface modification layer 201 of the fabric substrate 200 as a mutually regular adhesive pattern, The dot bonding member 110 is transferred onto the surface modification layer 201 of the fabric base material 200 and the surface modification layer 201 of the fabric base material 200 201). ≪ / RTI >

The dot bonding member 110 may be formed of a material selected from the group consisting of polyamide, polyester, polyurethane, polyolefin, and ethylene vinyl acetate (EVA), polyester, PVC A hot-melt adhesive made of one of the materials is preferable.

At this time, the melting point of the dot bonding member 110 is preferably 150 ° C or less, and the melt index is preferably 5 to 500 cm 3/10 min.

That is, when the melt index is less than 5 cm 3/10 min, the adhesion force of the dot bonding member 110 to the fabric base material 200 and the membrane 300 is deteriorated. If the melt adhesion index exceeds 500 cm 3 / (110) penetrates into the fabric base material (200) and the membrane (300), and the water pressure is lowered.

The fabric base material 200 is a front fabric of the moisture-permeable and waterproof fabric, and is exposed to the outside to directly affect the appearance of the clothes, so that the fabric base material 200 should have a relatively high density woven fabric. For example, the fabric substrate 200 includes all materials for fabricating casual suits, sports suits, etc., as fabrics, such as fabrics.

When the moisture permeable and waterproof fabric is worn, the membrane 300 performs a substantial moisture permeable and waterproof function of passing moisture vapor of sweat discharged from the human body and discharging it to the outside of the fabric and blocking the liquid penetrating the human body from outside the fabric.

In order to perform the moisture permeable and waterproof function, the membrane 300 may be used as a nanofiber web having a fine pore structure formed by accumulating nanofibers made of a polymer material.

That is, the membrane 300 is formed by electrospinning a spinning solution in which a polymer material and a solvent are mixed to produce nanofibers, and laminating the nanofibers.

Here, the electrospinning method applied to the present invention may be any one of general electrospinning, air-electrospinning (AES), centrifugal electrospinning, and flash-electrospinning It is also possible to use.

The polymeric material used in the present invention is capable of electrospinning, for example, a hydrophilic polymer and a hydrophobic polymer, and one or more of these polymers may be used in combination.

The polymer material usable in the present invention is not particularly limited as long as it is soluble in an organic solvent for electrospinning and is capable of forming nanofibers by electrospinning. For example, polyvinylidene fluoride (PVdF), poly (vinylidene fluoride-co-hexafluoropropylene), perfluoropolymers, polyvinyl chloride, polyvinylidene chloride or copolymers thereof, polyethylene glycol di Polyoxyethylene-polyoxypropylene oxide, polyethylene glycol derivatives including alkyl ethers and polyethylene glycol dialkyl esters, polyoxides including poly (oxymethylene-oligo-oxyethylene), polyethylene oxide and polypropylene oxide, polyvinyl acetate, poly (vinylpyrrolidone- Vinyl acetate), polystyrene and polystyrene acrylonitrile copolymers, polyacrylonitrile (PAN), polyacrylonitrile copolymers including polyacrylonitrile methyl methacrylate copolymers, polymethyl methacrylate, polymethyl methacrylate Acrylate copolymer or a mixture thereof.

Examples of usable polymer materials include polyamide, polyimide, polyamideimide, poly (meta-phenylene isophthalamide), polysulfone, polyetherketone, polyetherimide, polyethylene terephthalate, , Aromatic polyesters such as polyethylene naphthalate, polyphosphazenes such as polytetrafluoroethylene, polydiphenoxaphospazene, poly {bis [2- (2-methoxyethoxy) Polyurethane copolymers including polyether urethanes, cellulose acetate, cellulose acetate butyrate, and cellulose acetate propionate.

Among the above polymer materials, PAN, polyvinylidene fluoride (PVdF), polyester sulfone (PES) and polystyrene (PS) may be used alone, or polyvinylidene fluoride (PVdF) and polyacrylonitrile ) Or PVDF, PES, PVdF and thermoplastic polyurethane (TPU) may be mixed and used.

Accordingly, the polymer usable in the present invention is not particularly limited to thermosetting and thermosetting polymers capable of electrospinning.

The polymer material in the spinning solution is preferably 5 to 22.5% by weight.

If the content of the polymer material is less than 5% by weight, it is difficult to form a fibrous phase, and even if a particle is formed or spun by the spinning without spraying, a bead ), And the volatilization of the solvent is not performed well, so that during the calendering process of the web, the nanofiber web is melted and the pores are clogged. When the content of the polymer material exceeds 22.5% by weight, the viscosity increases and solidification occurs on the surface of the solution, which makes it difficult to spin for a long time, and fiber diameter can not be increased to make a fibrous shape of less than a micrometer size.

For the solvent to be mixed with the polymer substance for preparing the spinning solution, a mono-component solvent such as dimethylformamide (DMF) may be used. In the case of using the two-component solvent, the boiling point it is preferable to use a two-component solvent in which the higher and the lower one are mixed.

In the two-component mixed solvent according to the present invention, the high boiling point solvent and the low boiling point solvent are preferably mixed in a weight ratio of 7: 3 to 9: 1. When the amount of the high boiling point solvent is less than 7, there is a problem that the polymer is not completely dissolved. When the amount of the high boiling point solvent is more than 9, the amount of the low boiling point solvent is too small. The problem that can not be done occurs.

If only a solvent having a high boiling point is used, spinning can not be performed and spraying is performed to form a lot of beads even if particles are formed or spun, The volatilization of the solvent is not performed well, so that during the laminating process of the web, the partial melting occurs and the pore is clogged.

In addition, when only a solvent having a low boiling point is used, since volatilization of the solvent occurs very rapidly, many fibers are generated on the needles of the spinning nozzle and act as a source of radiation trouble.

In the present invention, when the polymer material is PES and PVdF, respectively, the two-component mixed solvent is, for example, acetone (BP-56) as a high boiling point solvent, DMAc (N, N-Dimethylacetoamide: BP- N-methylpyrrolidone (BP-202 ~ 204 ° C) and THF (Terahydrofuran: BP-67 ℃) were mixed in a weight ratio of 9: 1 : 1 by weight.

In this case, the mixing ratio between the two-component mixed solvent and the entire polymer material is preferably set to about 8: 2 by weight.

The spinning solution obtained by mixing the polymer material and the solvent is electrospun using a multi-hole spinning pack to obtain a multi-layered nanofiber web, and a thermocompression process, for example, calendering is performed.

Calendering is performed at a high temperature and a high pressure at about 70 to 190 DEG C so that the pore size of the nanofiber web becomes 0.8 mu m or less.

In the present invention, when the nanofiber web is formed, the nanofiber accumulation amount is set to 3 to 15 gsm to accumulate nanofibers having a low weight to form a lightweight nanofiber web, and the fabric base is adhered to the lightweight nanofiber web, The weight and manufacturing cost of the moisture permeable waterproof fabric can be reduced.

Referring to FIG. 2, a method of manufacturing a moisture-permeable and waterproof fabric according to a first embodiment of the present invention includes forming a surface modification layer 201 on a bonding surface of a fabric substrate 200 (S100) The dot bonding member 110 is transferred to the surface modification layer 201 of the fabric base material 200 to adhere one surface of the dot bonding material 110 to the surface modification layer 201 of the fabric base material 200 (S110). Thereafter, the membrane 300 is bonded to the other surface of the dot bonding member 110 (S120).

The surface modification layer 201 can be formed by various processes such as a corona treatment process and a plasma treatment process.

For example, the corona treatment can be performed by irradiating the fabric substrate 200 with a corona discharge to feed the fabric substrate 200 to the processing roll 700 as shown in FIG. 3, A corona discharge generated by applying a high frequency or a high voltage between the discharge electrodes of the corona discharging unit 730 is irradiated to the fabric base material 200.

The corona discharging unit 730 receives the high frequency or high voltage from the power source 750 and the fabric substrate 200 guided by the first guide roll 710 is fed to the processing roll 700, The base material 200 is guided to the second guide roll 720 to bond the dot bonding member.

In the present invention, the corona discharge portion 730 is opposed to the processing roll 700, and immediately after the corona treatment is performed on the fabric base material 200 fed to the processing roll 700, The dot-bonding member is bonded to the surface-modifying layer formed on the substrate.

That is, after the corona discharge is applied to the fabric base material 200 to form the surface modification layer 201 on the fabric base material 200, the fabric base material 200 is guided by the guide roll, The dot adhesion member 110 is adhered to the surface modification layer 201 of the fabric base material 200 in a state in which the surface modification is maximally preserved by performing the process of transferring and adhering the adhesion member 110, It is possible to maximize the adhesive force between the adhesive 200 and the dot bonding member 110 to prevent the dot bonding member 110 from peeling off from the fabric base material 200 and shorten the manufacturing process time.

Referring to FIGS. 4A and 4B, in the method of transferring and bonding the dot bonding member according to the present invention, the dot bonding member 110 is first transferred to the transfer auxiliary film 100 (FIG. 4A). Here, the transfer assisting film 100 is a film for transferring the dot bonding member 110 to the fabric substrate 200 in a process described later, and a polymer film can be used. Typically, PET is preferably used.

Thereafter, the dot bonding member 110 transferred to the transfer assisting film 100 is transferred to the surface modification layer 201 of the fabric base material 200 (Fig. 4B).

The step of transferring the dot adhesion member 110 transferred to the transfer assisting film 100 onto the woven base material 200 may be performed by attaching the woven base material 200 onto the dot adhesion member 110 transferred to the transfer assisting film 100, And then the transfer assisting film 100 is peeled from the dot bonding member 110 to leave only the dot bonding member 110 on the fabric base material 200. [

When the transfer assisting film 100 and the fabric substrate 200 are thermally bonded by the dot bonding member 110, the molten dot bonding member 110 is adhered only to the surface of the transfer assisting film 100, 200 have a plurality of pores between the yarns because the yarns are formed by woven yarns so that the molten adhesive flows into the pores of the fabric base material 200 including the surface modification layer 201 and is coated and adhered to the side walls of the pores, .

Therefore, the adhesive force between the transfer auxiliary film 100 and the dot bonding member 110 is significantly lower than the adhesive force between the fabric base member 200 and the dot bonding member 110, and the dot bonding member 110 is bonded to the fabric base member 200 The transfer assistant film 100 is peeled off from the dot adhesion member 110 by applying a predetermined physical force capable of maintaining the adhered state so that the transfer assisting film 100 is peeled from the dot adhesion member 110 It can peel off.

The thickness t of the dot bonding member 110 described above is preferably 30 to 50 占 퐉.

5 is a plan view showing a state in which a dot bonding member is adhered to the membrane of the moisture permeable and waterproof fabric according to the present invention. The dot bonding member is transferred and adhered to the surface modification layer 201 of the membrane, 111, 112, and 113 are formed in a regularly spaced pattern.

In this case, the diameter D of the plurality of dot-type adhesives 111, 112 and 113 is preferably 100 to 500 μm, and the distance L between the plurality of dot-type adhesives 111, 112 and 113 is preferably 100 to 400 μm.

When the diameter D of the dot type adhesives 111, 112 and 113 and the distance L between the dot type adhesives 111, 112 and 113 are less than 100 m, the amount of the dot bonding member 110 is small and the adhesive force is decreased, and the diameters of the dot type adhesives 111, 112, When the distance L between the dot-type adhesives 111, 112 and 113 exceeds 400 mu m, the amount of the dot adhesion member 110 increases so that the adhesive material penetrates into the fabric base material 200 and the membrane 300 So that the adhesive material escapes to the outside of the fabric or the pores of the membrane 300 are blocked by the adhesive material.

If the thickness t of the dot bonding member 110 is less than 30 占 퐉, the adhesive force decreases. If the thickness t exceeds 50 占 퐉, the adhesive material penetrates into the fabric base material 200 and the membrane 300, resulting in the same problem.

Referring to FIG. 6, the moisture-permeable and waterproof fabric according to the second embodiment of the present invention includes a fabric substrate 200; A surface modification layer (201) formed on a bonding surface of the fabric substrate (200); A dot adhesion member 110 transferred to the surface modification layer 201 and adhered to one surface thereof; A membrane 300 having one surface bonded to the other surface of the dot bonding member 110; And a lining fabric substrate 810 bonded to the other side of the membrane 300 with an adhesive web 800 having perforations.

Here, the adhesive web 800 for bonding the membrane 300 and the lining fabric base material 810 can be used as a sheeted hot-melt web.

The fabric base material 200 and the lining fabric base material 810 may be embodied by incorporating all materials for fabricating casual suits, sports suits and the like as fabrics including fabric.

Since the fabric substrate 200 is exposed to the outside of the moisture permeable and waterproof fabric and the lining fabric base material 810 is opposed to the human body, the weaving density of the lining fabric base material 810 is higher than that of the fabric base material 100 It is preferable that the weaving density is relatively lower than the weaving density.

That is, when the moisture-permeable and waterproof fabric is made into a garment, the fabric base material 200 is exposed to the outside and directly affects the outer appearance of the clothes. Therefore, the fabric base material 810 must have a relatively high- It is desirable to have a relatively low density woven fabric in order to reduce the manufacturing cost since it is required to have only a limited function for protecting the membrane 300 in proximity to the human body. For this reason, lining fabric substrate 810 may be referred to as a back fabric.

7 is a view showing the construction of an apparatus for manufacturing a moisture-permeable and waterproof fabric according to the present invention.

 The dot bonding member 110 transferred to the cooling fan 615 located between the guide rolls 611 and 612 is cooled and the fabric base material 200 fed from the winding roll 620 by the guide roll 621 is fed The dot adhesion member 110 is bonded to the transferred transfer assisting film 100.

Then, the lapped transcription assisting film 100 and the fabric substrate 200 are thermally adhered to each other by the heating rolls 631 and 632, and then the transcription assisting film 100 is peeled and wound on the take-up roll 650.

Subsequently, the membrane 300 supplied from the winding roll 660 is brought into contact with the dot bonding member 110 of the woven fabric base material 200 from which the transfer assisting film 100 has been peeled off so that the heating rolls 661, And the membrane 300 are thermally adhered to each other.

The heating rolls 631, 632, 661 and 662 described above may be calendering rolls for applying heat and pressure and the thermal adhesion of the lapped transcription assistant film 100 and the fabric substrate 200 or the fabric substrate 200 to the membrane 300 The laminate is subjected to heat and pressure applied by a hot roll rendering roll to thermally adhere.

In the present invention, '620' may be a take-up roll in which a fabric base material 200 on which the surface modification layer 201 is formed is wound, and the fabric base material 200 on which the surface modification layer 201 is formed, And may perform the function of the second guide roll for guiding. In this case, the first guide roll 710, the processing roll 700, the corona discharge unit 730, and the like in Fig. 3 are further included in the apparatus.
