Description

FIELD OF THE INVENTION [0001] The present invention relates to a method of manufacturing an outer cover fabric and a method of manufacturing the outer cover fabric,

The present invention relates to a jacket fabric of a protective clothing used for the purpose of protecting the body of people handling toxic chemicals in the gas or liquid state, and a method for producing the jacket fabric.

Researches on adsorbent layers and selective permeable membranes have been actively pursued in academia in order to absorb or block chemical substances. Toxic chemicals generally refer to organic compounds and substances used in chemical or biological warfare. Toxic agents that must be blocked for the protection of the body may include toxic chemicals or biological materials or combinations of one or more substances. The chemical inorganic agent may include one or more of a foaming agent or a nerve agent, a vesiculating agent, a tear gas or a vaginal agent, or a blood agonist.

The blister agents may include sulfur mustard, nitrogen mustard, phosgene (CX) or erosive gas (Lewisite), and the like.

The new economy may include one or more of Sarin · GB to Tabun · GA, Soman · GD or Novichok.

Tear agents may include one or more of diphenyl cyan to adamantium, chlorobenzyl malononitrile, chloroacetophenone, capsaicin, analogs and / or derivatives thereof, and the like.

The vaginal agent may include phosgene and diphosgene, chloropicin, and the like.

Blood agents may include hydrogen cyanide form and cyanide chloride.

Chemical protective clothing has been developed to resist these chemical weapon preparations, and chemical protective clothing is being divided into impermeable, permeable or permeable to toxic chemicals.

The initial chemical protective clothing was made by applying rubber or neoprene (a kind of rubber). As a result, the initial chemical protective clothing was very thick and impermeable, which increased the fatigue of the wearer in a short period of time and could lead to sudden physical and mental problems. To solve this problem, those prepared by impregnating activated carbon having excellent adsorption performance or coating or laminating in the form of beads have been recently used.

The permeable activated carbon protective clothing was provided through the US military's JSLIST program. The permeable activated carbon protective clothing is a protection of Saratoga type that satisfies the purpose of reducing the logistics burden by improving the protection performance and durability, reducing the thermal fatigue through air permeation, and providing comfort. However, since the activated carbon is used, the adsorption progresses at the same time when the wrapping paper is opened, resulting in deterioration of the protective performance, saturation of the activated carbon adsorption capacity, and loss of function of the product.

In order to reduce thermal fatigue, impermeable protective garments have not provided perfect protection against aerosols or biological agents because of the presence of pores between the fibrous and activated carbon layers.

In recent years, selective permeable membranes have been used as new protective materials to reduce thermal fatigue and protect chemical biological agents. The selective permeable membrane is excellent in water vapor permeability and permeates smoothly to toxic chemicals in gas and liquid form. Therefore, it is difficult to control toxic materials only with a pore-type selectively permeable membrane of a single layer, and an additional protective membrane is introduced into a pore-type selective permeable membrane or a combination of two or more selective permeable membranes is used.

The permeable membrane through this combination prevents or prevents permeation of gases, liquids, aerosol chemical agents, viruses and the like, while improving the thermal fatigue by discharging the water vapor emitted from the human body. In addition, it has the advantage of being thinner and lighter than impermeable protective clothing and activated carbon protective clothing. However, the cost of protective clothing using selective permeable membrane is very high. In addition, since the selective permeable membrane is provided by coating or laminating on the protective jacket skin, the properties of the jacket can greatly affect the properties of the protective clothing.

Research and development on toxic chemical protective clothing mainly adsorbed or selective permeable materials have been carried out. The protective jacket material is provided in Korean Patent No. 10-2006-0059999. Protective clothing using a selective permeable membrane material is provided in Korean Patent Laid-Open Nos. 10-2008-0081913 and 10-2010-0065069.

It is preferable that the protective clothing using the permeable protective clothing or the selective permeable film using activated carbon has a protective power from the outer skin which is a portion where the gas or liquid chemical substance first comes into contact with the product. However, technical proposals for a shell that first contacts toxic chemicals in protective clothing against toxic chemicals are marginal.

It is an object of the present invention to provide a jacket fabric of a protective garment having a suitable composition and shape to protect the human body from toxic chemicals. In particular, it is intended to provide a shell fabric having permeation resistance to gas or liquid toxic chemicals.

FIG. 3 is a flow chart of a method of manufacturing a shell fabric according to an embodiment of the present invention.

The method of fabricating the outer fabric includes weaving the fabric (S100), stomach-printing (S200), and heat-treating (S300). Further, the method may further include a step (S400) of coating with a hydrophilic polymer.

The step of weaving the fabric fabric (S100) weaves the fabric fabric with a composite yarn of polyester short fibers and cellulose fibers. The polyester staple fibers may use staple fibers having a strength of 1.0 to 5.0 g / d, an elongation of 10 to 80%, and a fiber length of 38 to 78 mm.

Composite yarns are formed by mixing polyester short fibers and cellulose fibers. At least one of the antioxidant, antimicrobial agent, deodorant, fluorescent brightening agent and flame retardant described in Fig. 1 may be added to the polyester staple fiber. If polyester short fibers and cellulose fibers are intermingled, composite yarns can be formed through a process of softening, softening, coarse and square spinning. In the fibers in which the polyester short fibers and the cellulose fibers are blended, the cellulose fibers may be present at about 15 to 80% by weight based on the total weight. In the process of forming the composite yarn, it is preferable to carry out the somen surface sliver step.

The sphere sliver can be carded, stretched, folded up to three times or less, re-stretched, and the stretched sliver is converted into an irradiance, and the irradiation is processed into a square yarn through a ring-square or air jet square process to form a composite yarn .

The woven fabric woven with the composite yarn of polyester short fibers and cellulose fibers may have a weight per unit area of 200 to 400 g / m ² . The weaving may be formed into a fabric fabric through an air-jet room, a water-jet room, or a labier room facility. Preferably, the tissue is plain to transitional plain weave, twill, satin.

Subsequently, the cloth is printed so as to give a reflectance to each of the near infrared ray regions (S200). Camouflage printing is as specified in the National Defense Standard (KDS 8305-1044). The same is applied to the defense specification in connection with FIG.

Finally, heat treatment is performed using a fluorine-based water repellent agent so as to impart water repellency to the stomach-printed textile fabric (S300).

The fluorine-based water repellent agent for fibers is preferably treated at 40 to 80 g / L. Specifically, 1 g of the fluorine-based water repellent agent is dried at 100 ° C. for 1 hour, and the heat treatment is preferably performed using 17% to 32% of the fluorine-containing water repellent containing the perfluoro compound.

The solids content is calculated as Solid content = (W ₁ -W ₂ ) / W ₁ x 100, where W ₁ is the weight before treatment and W ₂ is the weight after drying.

A zeolite to neutralize the toxic chemical substance or give the activity to the microorganism during the treatment of the fluorine-based water repellent agent; A quaternary ammonium compound (for example, a polyoxyalkyl trialkyl ammonium chloride and an organosilicon quaternary ammonium salt to which trimethoxysilyl is attached to quaternary ammonium); Phenolic compounds; A tin-ion compound, a copper-ion compound, a zinc-ion compound, an organic compound containing a silver-ion compound; Natural compounds including chitosan, hinokitiol, aminoglucoside; Guanidine compounds; And at least one selected from the group consisting of metal compounds coordinated to the fibers (for example, silver sulphonate, iron phthalocyanine, metal oxide coordination amino silicon polymer, zinc sulfate coordinated acrylic acid polymer) can further be used for heat treatment.

After the heat treatment using the fluorine-based water repellent agent, the hydrophilic polymer may be coated to form a selective permeable membrane that imparts additional permeation resistance of the toxic chemical (S400). The hydrophilic polymer may be polyvinyl alcohol or polyvinyl alcohol covinylamine, and the cross-linking agent described in Fig. 2 may be used together to improve the water resistance.

The prepared composite solution (2) was thoroughly degassed after filtration through a 120 mesh network, after being aged at room temperature for 48 hours in a sealed state.

A crosslinking agent (polyamide epichlorohydrin, Hercules, USA) was added to the composite solution (2), and the mixture was stirred at 200 rpm for 2 hours at room temperature, followed by crosslinking reaction. The mixture was stirred at 100 rpm for 1 h at room temperature using block diisocyanate (AH-2200, Aekyung Chemical Co., Ltd., Korea). The mixture was stirred at 100 rpm for 30 minutes using a defoaming agent (trade name LDC 220A, Dow Corning), a dispersing agent (trade name: 2-9147 LF, Dow Corning, USA) and a humectant (trade name Q2-5212, Dow Corning, USA) The solution (3) was prepared.

Based on the prepared composite solution (3), application was carried out by a dry knife coating method on the outer surface of the outer fabric. Baker applicator (Yosimitsu YBA 6 type) was used for the coating and the coating was repeated 5 times on the dyed / water repaired fabric and applied 50g / ㎡ to the fabric weight. The coating amount was 10 g / m < 2 > to 15 g / m < 2 > at one time of coating, and the drying temperature was 150 DEG C for 3 minutes.

First, expanded polytetrafluoroetraene (General Electric) was bonded on a 50 g / m 2 coated fabric using a prefabricated adhesive (V-coat 6360, VIX), dried and then dried at 90 ° C Aging was carried out for 5 hours.

The composite solution (3), which was fabricated on expanded polytetrafluoroetrene (General Electric) bonded fabrics, was coated with 40 g / cm ² on the basis of the weight of the fabric repeatedly coated four times. The coating was 1 hoesi coating amount is ^{10g / m 2 ~ 15g / m} 2, drying was carried out at 150 ℃ 2 bun while.

The water vapor permeability (MVTR) of the manufactured product can be at least 2,000 g / m < 2 > 24 hours, more preferably at least about 2,000 g / m & 24 hr to about 4,000 g / m 2 24 hr, about 4,000 g / m 2 24 hr to about 5,000 g / m 2 24 hr, and about 5,000 g / m 2 24 hr to about 6,000 g / m 2 24 hr.

Finally, a tricoat was laminated on the second coated fabric using a starting adhesive (V-coat 6360, VIX) to prepare a product. Table 4 shows the measured DMMP permeability of the manufactured products.

The outer covering material of the protective clothing provided in the present invention has an initial footstock degree of 5 as measured by the KS K 0590 method, and has a foot number of 3 measured by the KS K 0590 method after washing five times by the KS K ISO 6330 (B2) method And the dimensional change ratio measured by the KS K ISO 5077 method is within ± 2% in both the warp direction and the warp direction, and the wash fastness measured by the KS K 0430 method, the sweat fastness measured by the KS K 0715 method, All of the fastnesses measured by the method are more than grade 4, and both have excellent functionality and durability.
