Description

{MULTI FUNCTION TEXTILES FOR SPECIAL SUIT}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a special-purpose fabric, and more particularly, to a special-use fabric used in a special garment such as a fire suit or a chemical protective suit.

Generally, fire-fighting clothing is required to have heat resistance, flame retardancy and water resistance, and the outer surface is made of aramid fabric which is excellent in heat resistance and flame retardancy. Such firefighter suits are lined with quilted lining on the inside of the aramid fabric, and the heat is insulated through the lining. However, since the general fire fighting suit is composed of the lining made of the outer material and the quilting made of the aramid fabric as described above, there is a problem that when a fire occurs in the chemical depository, it is vulnerable to toxic chemicals in liquid or meteorological conditions. If it is caught, the outer surface may be torn and poisonous substances may be introduced.

On the other hand, chemical protective clothing is required to be waterproof and chemical resistant, and is used in CBR or industrial sites contaminated with hazardous chemicals. Such chemical protective clothing is made of a fabric such as aramid or nylon coated with a protective layer excellent in heat resistance and chemical resistance.

Prior arts therefor are chemical protective clothing fabrics and chemical protective clothing according to Korean Patent No. 10-929207 registered and proposed by the present applicant.

The chemical protective clothing fabric of this prior art (hereinafter, referred to as "first prior art") comprises a textile fabric 1 as shown in Fig. 1, a chloroprene rubber layer A chloroprene rubber layer 12, an adhesive 10, a fluorine-based polymer layer 16, and a chemically protective film 12, which are sequentially laminated on the back surface of the fabric 1, a butyl rubber layer 14, a fluoropolymer layer 16, (22).

However, the chemical protective clothing fabric according to the first prior art has a complicated construction due to the complicated structure because the chloroprene rubber layers 12 are laminated on both surfaces of the fabric 1, Since the rubber layer is provided on both sides, it is too heavy to manufacture chemical protective clothing.

In particular, the chemical protective clothing fabric according to the first prior art has a problem that, as shown in Fig. 1, the film layer 22 provided on the inner side of the fabric 1 is formed as a flat thin film and tears easily due to wrinkling or impact And thus chemical substances may penetrate through the tear gap of the film layer 22 when it is made of a chemical protective garment.

Accordingly, the applicant of the present invention has developed another technique capable of solving the above-mentioned problems, and then applied for a patent to the Korean Intellectual Property Office and registered with Registration No. 10-1286338 (chemical protective clothing fabric and chemical protective clothing therefrom) There is a bar.

Another prior art patent (hereinafter referred to as " second prior art ") comprises a rubber layer 31 laminated on one side of a fibrous layer 32 formed of fibrous material in the form of a thin film, And at least one film layer 33 laminated in the form of a thin film on the other side of the film 32 to prevent penetration of toxic chemicals and formed with an extruded pattern 33h formed of a pattern or concavo-convex pattern in the direction of extrusion .

In the chemical protective clothing fabric according to the second prior art and the chemical protective clothing according to the second conventional technology, the straight extruded pattern 33h is formed on the surface of the film layer 33 constituting the fabric so that the rigidity of the film layer is reinforced Tearing can be prevented.

However, in the second conventional technique as described above, since the film layer 33 is attached to the other side of the fibrous layer 32 to which the rubber layer 31 is attached on one side, the fabric becomes too stiff or brittle. This is because the film layer 33 having a small elasticity is attached to the rubber layer 31 having a high elasticity, so that the film layer 33 suppresses the elongation of the rubber layer 31 due to the difference in elastic force. Particularly, in the second conventional technique, the fibrous layer 32 is originally made of a stiff material. However, as the rubber layer 31 and the film layer 33 are bonded to the fibrous layer 32, the fabric becomes more stiff or brittle. Therefore, when the chemical protective clothing is manufactured using the fabric according to the second conventional technique described above, the feeling of wearing may be lowered and the activity may be deteriorated.

To improve this, Korean Patent Registration No. 10-1407688 (hereinafter, referred to as "third prior art"), which is filed and registered by the applicant of the present invention, 2 A stretchable strained layer made of a membrane made of a Teflon-based resin, a fluorine-based resin, or a polyurethane-based resin and having a rubber-like elasticity is provided between the fibrous layer 32 and the film layer 33, 41).

Such a third prior art technique can prevent the elastic force of the rubber layer 31 and the film layer 33 from being buffered while being elastically deformed in an isotropic manner with the rubber material resin material as described above, It is possible to improve the fit of the garment. In addition, since the film layer 33 is composed of the plurality of films 33a, 33b, and 33c on which the above-described extrusion pattern 33h is formed, not only can the tearing be further prevented, but also the toxic chemicals can be more reliably prevented It is possible.

However, in the third conventional technique, a soft rubber layer 31 is formed on one side of the fiber layer 32, and a plurality of film layers 33 are formed on the other side of the fiber layer 32 And the resinous stretchable and deformable layer 41 is provided between the fibrous layer 32 and the film layer 33, so that the overall weight is excessively increased, and thus the activity is lowered.

Particularly, since the stretchable deformable layer 41 composed of the thin film resin material membrane is formed of a planar member such as vinyl, the weight excessively increases.

On the other hand, as described above, the fire extinguishers and the chemical protective suits have different fabric structures as described above, and the fabrics are manufactured individually. Therefore, the fabrics for fire extinguishers and chemical protective apparels are manufactured separately, which increases the manufacturing cost of the manufacturers.

The applicant of the present invention can apply the present invention to both fire extinguishers and chemical protective suits in order to reduce manufacturing cost of the fire extinguisher and chemical protective suit fabrics. The inventor of the present invention has applied the present invention by researching and developing a fabric capable of solving the above- .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a multifunctional fabric for special use according to an embodiment of the present invention will be described with reference to the accompanying drawings.

The multifunctional multi-functional fabric according to the embodiment of the present invention includes a first sheet 111, a second sheet 112 and a third sheet 114 as shown in FIG.

The first sheet 111 is composed of a flat fiber cloth having heat resistance and toughness so that it can be used as a fire extinguisher. The first sheet 111 may be composed of a fabric but may also be composed of a nonwoven fabric. The first sheet 111 faces the external water or fire or poisonous substance on the upper surface opposite to the second sheet 112 as shown in Fig. The first sheet 111 may be composed of at least one of aramid fibers having heat resistance and toughness, reinforcing fibers made of at least one of carbon fibers and flon fibers, or high-strength polyester fibers or nylon fibers have. The first sheet 111 is particularly preferably made of PBO (poly-phenylene benzobisoxazole) or para-aramid having high strength and excellent heat resistance and tensile strength. Therefore, the first sheet 111 can block the fire by the material characteristics.

As shown in FIG. 5, the second sheet 112 is integrally provided on the bottom surface opposite to the top surface of the first sheet 111, and is integrally formed with the first sheet 111. The second sheet 112 is made of a waterproof film having chemical resistance to provide waterproofing and chemical resistance to the bottom surface of the first sheet 111 to shield the bottom surface of the first sheet 111 in a water tight state. The second sheet 112 is constructed of a film to block toxic substances in liquid, vapor or powder form. The second sheet 112 is made of a film and has a stretchability different from that of the first sheet 111 made of fibers.

The second sheet 112 is made of, for example, a resin film made of PE (polyethylene), PET (polyethylene terephthalate) or PTFE (Polytetrafluoroethylene) which has particularly strong chemical resistance to liquid toxic chemicals, Resin material films made of EVOH (Ethylenevinyl alcohol) having strong chemical resistance, Resin material films made of ETFE (Ethylene tetra fluoro ethylene) having particularly strong chemical resistance against strongly acidic and alkaline chemicals, And a fluorine film having chemical resistance. That is, the second sheet 112 is made of an chemical-resistant film made of any one of PE, PET, PTFE, EVOH, ETFE, and fluorine.

The second sheet 112 is formed of an extruded film by extrusion molding. As shown in Fig. 4, a molded or embossed mold 112h forming a texture in the extrusion direction is formed on the surface in the extrusion molding. The second sheet 112 has a striped molding pattern 112h on its surface as a side of the second sheet 112 is pulled at the time of molding to form very fine wrinkles on the surface. Since the second sheet 112 is formed by the fine wrinkles, the formed pattern 112h is formed in a substantially fine concave-convex pattern, the toughness is enhanced by the molded pattern 112h. Particularly, the second sheet 112 is strengthened in toughness along the molding pattern 112h, so that its own strength is substantially strengthened. As the molding pattern 112h is formed obliquely with respect to the longitudinal direction as shown, The personality is strengthened. Such a film layer 112 is a typical cross-laminate, and its manufacturing method and characteristics are comparatively small, so that a detailed description thereof will be omitted.

The third sheet 114 is integrally formed with the first sheet 111 and the second sheet 112 in a state interposed between the first sheet 111 and the second sheet 112 as shown, The first sheet 111 and the second sheet 112 are disposed between the first sheet 111 and the second sheet 112 having different elasticity. The third sheet 114 is sandwiched between the first sheet 111 and the second sheet 112 1112 < / RTI >

 The third sheet 114 is a member made of a material having elasticity such as isotropic and is a planar member that elastically supports the first sheet 111 and the second sheet 112. The third sheet 114 compresses the different stretchability of the first sheet 111 and the second sheet 112 while expanding and contracting between the first sheet 111 and the second sheet 112 by material properties. That is, the third sheet 114 is stretched and contracted in various directions between the first sheet 111 and the second sheet 112, which are different in elasticity due to the elastic difference due to the material characteristics, (I.e., different elastic forces) from each other. Accordingly, the third sheet 114 is improved in flexibility when the fabric 110 according to an embodiment of the present invention is manufactured from a fire extinguisher or a chemical protective garment, thereby providing excellent wearing comfort.

4 and 5, the third sheet 114 is provided with an air layer such as a heat insulating space between the first sheet 111 and the second sheet 112 to improve the heat resistance, (114a) is formed. The third sheet 114 may be composed of a thin membrane made of a soft chemical material having rubber elasticity and stretchable between the first sheet 111 and the second sheet 112, for example. That is, the third sheet 114 is a thin film or a wrap-like member having elasticity like rubber and stretching in various directions, not in one direction. The third sheet 114 may be made of various materials, but it is preferable that the third sheet 114 is made of a thin film membrane made of a Teflon resin, a fluorine resin, or a polyurethane resin having excellent heat and chemical resistance and excellent elasticity. Most preferably made of PTFE (Polytetrafluoroethylene) or TPU (Thermoplastic Polyurethane) having excellent chemical and water resistance. Thus, the third sheet 114 not only expands and contracts between the first sheet 111 and the second sheet 112, but also provides chemical resistance. At this time, the third sheet 114 provides partial chemical resistance by the aforementioned pores 114a. The third sheet 114 is smoothly stretched and contracted because the rigidity thereof is partially weakened by the pores 114a.

8, the third sheet 114 is made of a stretchable yarn, for example, as shown in Fig. 8, and is stretched or deformed between the first sheet 111 and the second sheet 112, And a mesh fabric made up of a coat. In this case, the third sheet 114 is not only reduced in weight due to the mesh of the knit or tricot but also smoothly stretched. As shown in FIG. 8, the third sheet 114 is naturally formed with the pores 114a by the mesh, so that the pores 114a need not be separately formed, and the air layer providing the heat- .

Alternatively, the third sheet 114 may be constructed from an air mesh fabric as shown in Fig. The air mesh fabric is made of a hollow fiber and is stretchable, and is formed like a mesh by a fine mesh that forms the pores 114a as shown in the figure. Accordingly, when the third sheet 114 is composed of an air mesh fabric, the weight is reduced not only by the hollow fiber and the mesh, but also by the expansion and contraction of the smooth sheet, and the air hole is provided by the mesh- Circulates the air that has passed through the first sheet 111 through the first sheet 111.

Alternatively, the third sheet 114 may be constructed of a three-dimensional air mesh 115 as shown in Figs. 10 and 11, for example. The three-dimensional air mesh 115 is composed of two filament yarns 115a and 115b and a filament yarn 115c connecting the two filament yarns 115a and 115b to provide an elastic force. The three-dimensional air mesh 115 can be manufactured (for example, in a ratio of 40%: 60%) by blending aramid fibers or para-aramid fibers having heat resistance or flame resistance or polybenzimidazole and para-aramid The filament yarn 115c moves toward the opposite fabric when an external force is applied to one of the mesh fabrics 115a and 115b and has an elastic force to restore the original state when the external force disappears. Accordingly, the three-dimensional air mesh 115 smoothly expands and contracts between the first sheet 111 and the second sheet 112 through the filament yarn 115c, and the air 114a and the filament yarn 115c Thereby circulating the air that has passed through the first sheet 111 or providing the above-described air layer.

The three-dimensional air mesh 115 may have different meshes (pores) formed on the mesh fabrics 115a and 115b. Accordingly, the elasticity (elasticity) and air permeability of the three-dimensional air mesh 115 can be controlled through the mesh sizes of the mesh fabrics 115a and 115b.

The three-dimensional air mesh 115 may be formed with a hollow H for providing pores in the end faces of the mesh fabrics 115a and 115b as shown in FIG. The hollow H communicates air circulated as described above to circulate air more smoothly. When the mesh fabrics 115a and 115b are compressed, they are expanded and contracted to provide elastic force to the mesh fabrics 115a and 115b. Accordingly, the three-dimensional air mesh 115 not only provides a more excellent elastic force but also provides a more improved fit through the cushioning action by the elastic force and provides an air layer through the hollow (H).

Meanwhile, it is preferable that the above-mentioned perforations 114a have a size that can be visually recognized without pulling the third sheet 114 to reduce the weight of the third sheet 114 and smoothly expand and contract.

On the other hand, the first sheet 111, the second sheet 112, and the third sheet 114 described above are formed as one sheet of fabric 110 as they are integrated with each other as shown in FIG. At this time, the fabric 110 is attached to the first sheet 111 after the second sheet 112 is preferentially put on the third sheet 114 to form the first sheet 111, the second sheet 112, It is preferable that the three sheets 114 are integrally manufactured. This is because the fabric 110 may be attached to the first sheet 111 as described later so that the weight of the first sheet 111 and the second sheet 1112 is too large It is preferable that the second sheet 112 is preferentially adhered to the third sheet 114 so as not to occur. Since the fabric 110 can prevent the infiltration of poisonous substances and moisture while blocking fire due to the heat resistance and toughness of the first sheet 111 and the waterproof and chemical resistance of the second sheet 112 made of a film, It can also be used for chemical protective clothing.

On the other hand, as described above, the second sheet 112 composed of a film may be composed of only one chemical film and may be composed of a single layer. However, the second sheet 112 may have a different chemical resistance It is preferable that the film is composed of one composite film in which at least two chemical-resistant films are laminated and composed of a plurality of layers. The second sheet 112 can protect the penetration of toxic chemicals in multiple stages when composed of multiple layers.

For example, the second sheet 112 may be a double composite film composed of a first layer 112a and a second layer 112b, which are joined together to form an identical body, as shown in FIG. In this case, the second sheet 112 may be made of any material selected so that the first layer 112a and the second layer 112b are prevented from overlapping with each other among the above-mentioned PEA, PET, PTFE, EVOH, ETFE, And is composed of a composite layer which is chemically differentiated from each other. Accordingly, since the first layer 112a and the second layer 112b are made of the chemical materials different from each other, the second sheet 112 is formed of the first layer 112a and the second layer 112b for various kinds of toxic chemicals. 112b to provide different chemical resistance to each other, as well as enhanced strength by the multiple layers. For example, when the first layer 112a is constituted by PE and the second layer 112b is constituted by EVOH, the second sheet 112 is primarily vaporized and liquidated through the first layer 112a, Particularly toxic chemicals in the liquid phase are filtered or defected and the vapor and liquid toxic chemicals passing through the first layer 112a through the second layer 112b are secondarily Filtering or defending, especially filtration or defense of toxic chemicals in the vapor phase.

The second sheet 112 may be formed only on the first layer 112a as shown in FIG. 4 so as to minimize the thickness of the first layer 112a and the second layer 112b to be laminated, And the second layer 112b may not be provided with the molding pattern 112h described above.

Alternatively, the first and second layers 112a and 112b may be laminated together with the molding pattern 112h as described above so that the overall toughness of the second sheet 112 may be increased even if the thickness is slightly increased And can be interlaced with each other as shown in FIG. 6 so that the toughness of each other is complementary to each other. The second sheet 112 may be laminated as the first layer 112a and the second layer 112b are in close contact with each other under the temperature and semi-molten state at the time of extrusion before being cooled after being extruded, They may be laminated and then joined together by high frequency welding, ultrasonic welding or an adhesive. Accordingly, the second sheet 112 is composed of a single film while the first layer 112a and the second layer 112b are formed of the same body.

The second sheet 112 may be a triple composite film in which the third layer 112c is additionally formed as shown in the enlarged view of FIG.

For example, when the first layer 112a is made of PE and the second layer 112b is made of EVOH, the second layer 112c overlaps with the second layer 112b, PE again to prevent lamination. The third layer 112c of the second sheet 112 primarily filters and protects the vapor and liquid toxic chemicals that have passed through the second layer 112b. Thus, the second sheet 112 can provide chemical resistance to a variety of toxic chemicals, and the strength is further enhanced by the third layer 112c.

The third layer 112c may not include the molding pattern 112b so that the thickness of the film layer 112 is minimized.

Here, the first sheet 111 may be further provided with the above-described third sheet 114 on the upper surface as shown in FIG. This additional third sheet 114 stretches between the first sheet 111 and the fourth sheet 118 and compensates for the difference in elasticity of the first sheet 111 and the fourth sheet 118 to improve the fit.

On the other hand, the fourth sheet 118 composed of the above-described film can be bonded to another second sheet 112, which is configured similarly to the above-described second sheet 112, as shown in Fig. Therefore, the fourth sheet 118 is shielded and protected by another second sheet 112, so that it is not easily damaged and its chemical resistance and water resistance are enhanced. At this time, the fourth sheet 118 may further include the third sheet 114 described above as shown in FIG. This additional third sheet 114 improves the fit of the fourth sheet 118 and the second sheet 112 by compensating for the elastic difference between the fourth sheet 118 and the second sheet 112 while elastically deforming .

On the other hand, as described above, the second sheet 112 provided on the bottom surface of the first sheet 111 has a third sheet made of a mesh fabric, an air mesh fabric or a three-dimensional air mesh, 114, respectively. That is, the second sheet 112 may be shielded from the bottom by another third sheet 114 configured similarly to the third sheet 114. [ The third sheet 114 is a fifth sheet which improves the feel through the cushion or absorbs perspiration to dry quickly.

The multifunctional multi-functional fabric 110 according to the embodiment of the present invention is composed of the first sheet 111, the second sheet 112 and the third sheet 114 as shown in FIGS. 4 and 5 It is used as a fire suit. Such a fabric 110 can be used as a fire extinguisher that prevents the penetration of toxic substances because the first sheet 111 made of aramid fibers blocks fire and the second sheet 112 made of film blocks toxic substances . Particularly, since the third sheet 114 of the fabric 110 is stretched and shrunk, the wearing feeling is excellent, and the weight of the fabric 110 is reduced by the pores 114a of the third sheet 114, It is possible to provide a fire extinguisher with improved performance. In addition, the fabric 110 may be provided with an improved durability because the rigidity is enhanced by the molding pattern 112h of the second sheet 112. [

12, when the fourth sheet 118 of the rubber material or the film material is provided on the surface of the first sheet 111, the fourth sheet 118 is separated from the first sheet 118 111), it can be used as the chemical protective clothing 100 as shown in FIG. As described above, the chemical protective clothing 100 is reduced in overall weight and improved in wearing comfort by the pores 114a of the third sheet 114 and the mesh fabric, the air mesh fabric or the three-dimensional air mesh, The durability is improved by the sheet 112.
