It is related to being formed uniformly active carbon in more detail to improve to whether there is or not the absorption properties of substance, and is not living in washing
Property charcoal fall off, and then can recycle after wash core biochemical agent adsorbent, noxious material adsorption filter, protection
Clothes and its manufacturing process.
Background technique
In general, it with the increase developed a large amount of antipersonnel weapon in modern war with hold country, is requiring
The product of human body or equipment can be protected.And the producing cost of chemical weapons is cheap in a large amount of antipersonnel weapons, and because
The manufacturing equipment of miniaturization can carry out mass production in a short time, and while be rela-tively easy to manage Threat nor
Chang Gao.
Accordingly, requiring production that can protect the various protective devices of human body, for example, be used in CB RN (chemical,
Bacteriological, radiological, or nuclear, chemistry, bacterium, radioactivity or core) NBC protection
Clothes and breathing mask etc..The type of NBC protection clothes is distinguished by the gas permeability of air, and gas permeability is broadly divided into
Protective garment and non-breathable protective garment.
Non-breathable protective garment is the closed protective clothing that can not make external fluid circulation, the protection to noxious material
Property it is outstanding, but have that be difficult will be from the vapor and hot air discharge distributed in vivo to external fatal defects.
On the contrary, breathable barrier clothes are different from non-breathable protective garment, certain fluid can be made to pass in and out, and due to having
Noxious material directly affects human body, thus using include can adsorb and filtering poisonous substance active carbon fabric and
The dual structure fabric of the fabric of camouflage function is assigned on the fabric.
The breathable barrier clothes the prior art have: Ebrean Registered Patent the 10-1041415th " improve it is flexible
Fabric is taken in chemical protection ", Ebrean Registered Patent the 10-1146573rd " absorption filtering material ", Ebrean Registered Patent
No. 10-1406311 " NBC protection clothing fabric and its NBC protection clothing ".
According to the above-mentioned prior art, constituted and had the following structure with liner by outer shell fabric: in order to from by gas with
And/or human body is protected in the noxious material of the fluid state of person's liquid composition, the outer shell fabric use is in terylene series fiber material
The fabric of the very thin latex rubber state of equal coatings protects liner, and that plays isolation liquid for the first time and solid state has
The effect of noxious material；The liner handles surface by active carbon to adsorb and remove noxious material using adhesive.
Especially, it is above-mentioned in the prior art, by being formed there is the adsorbent of shape of the porous bead of subtle stomata to be placed in
Between liner and outer shell fabric, and then adsorb simultaneously filtering poisonous substance.
But in the prior art (prior art 1) as described above, since adsorbent has porous bead shape,
Form gap between multiple pearls, and then because the gap exist can not filtering poisonous substance permeate asking for noxious material instead
Topic.
In addition, adsorbent is placed between liner and outer shell fabric as described above with the shape of pearl, only pearl is adsorbed accordingly
The top and lower part of agent are attached between outer shell fabric and liner, therefore beaded adsorbents can occur from outer layer in washing
The phenomenon that fabric and Fall of lining, and then there is the absorption property for passing through the significant decrease later of washing for several times to noxious material
Problem.
Meanwhile adsorbent need to be made beading, it is therefore desirable to excessively high manufacturing cost；And manufacturing process is very severe
It carves, therefore manufacturing cost is high；And the problem of not increasing there is only weight, and because weight increase is being used in protective garment
When there is also reduce activity the problem of.
Therefore, in order to solve the problem above-mentioned, (South Korea) market is had listed using powdered active carbon at home recently
Product rather than beaded adsorbents.The product (prior art 2) is only that active carbon powder is sprayed at merely to such as bonded fabric
It pressurizes after fabric, therefore there are problems that active carbon falls off from fabric when wearing the product carry out activity, Er Qie
A part of active carbon is lost when washing, therefore there is also can not recycle.
For the product, due to active carbon be it is powdered, using adhesive bonding in fabric, in this case
Active carbon is landfilled in adhesive, and then active carbon can not play adsorption function, especially adhesive and completely cut off fabric, cause
Fabric loses gas permeability, therefore has to active carbon being sprayed at fabric merely.

Hereinafter, referring to attached drawing the preferred embodiment of the present invention as described in detail below.
As shown in Figure 1, core biochemical agent adsorbent according to an embodiment of the present invention include Powdered Activated Carbon 11, matrix 12,
Solvent S and micro-particle filler A.
Matrix 12 is mixed active charcoal 11 and by from the liquid thermosetting property for being hardened to solid-like or thermoplastic material
Gel or colloid is constituted, and the adsorption layer of aftermentioned sheet form is provided after hardening.For example, the matrix 12 is in hardening at subcritical temerature item
It is also very outstanding with the bonding force of fiber under part and outstanding to the adhesion of fiber, and elasticity is assigned to adsorption layer, in turn
Can be used alone environment-friendly water-based polyurethane, to improve the durability of adsorption filter according to an embodiment of the present invention, Huo Zhegen
According to the physical property required in addition that, moisture-proof, hardness and the excellent acrylic resin of mouldability can be used alone or as a mixture
Or melamine resin and there is adhesiveness, rigidity, chemical resistance and heat-resistance epoxy resin, silicon, phenol and polyamide
Acid etc..Matrix 12 is combined in hardening with active carbon 11, to prevent active carbon 11 from flowing.That is, matrix 12 plays the work of adhesive
With.
As shown in Figure 1, active carbon 11, which is mixed in matrix 12, adsorbs noxious material by porous (not shown).That is, active carbon
11 absorption and the filtering noxious toxic chemical substance (such as, core biochemical agent or chemical substance) in human body, especially liquid
Shape or gasiform noxious material.Active carbon 11 be it is powdered, to be easy to be mixed in liquid matrix 12.
For example, active carbon 11 can be in graphene (graphene), graphite, metal oxide (Al2O3, Fe2O3、SiO2、
MgO、CaO、TiO2、ZnO、V2O5) middle exclusive use is one of or is used in mixed way two or more.Then, active carbon 11 can
Containing Cu, Ag, Fe, Ce, and then selective absorption performance can be improved according to the type of noxious material.
Active carbon 11 can hardening at subcritical temerature as described above, and flexibility is outstanding, is especially mixed at least by as follows
One of constitute matrix 12: be primarily adapted for use in require elasticity product polyurethane resin；Moisture-proof, hardness and at
The outstanding acrylic acid of type, melamine resin；Or have degree of adhesion, intensity, chemical resistance and heat-resistance epoxy resin,
Silicon, phenol, polyamic acid.
Preferably, active carbon 11 forms 0.1 μm to 300 μm granularity (size of particulate).The size of 11 particle of active carbon
Smaller then effective adsorption area is more outstanding, therefore the size of particle is the smaller the better.Preferably, compared to coconut by carbon system structure
Viability charcoal 11 is best.Because in the case where constituting active carbon 11 by coconut system, when carrying out aftermentioned heat treatment process
It is easy thermally stressed, therefore active carbon 11 is preferably constituted by the strong coal system of thermal stress.
As shown in Figure 1, solvent 12 is mixed in matrix 11, to prevent matrix 11 from hardening too quickly.For example, solvent S at least by
Substance with the compatibility with other compositions and the physical property of suitable hardening and operating condition is constituted.Preferably, should
Solvent S in aftermentioned heat treatment process the substance of thermal evaporation or drying or even dissipation by being made up of.Then, preferably
Solvent S is by having the compatibility and for workability desired time during remaining substance structure compatible with matrix 12
At.For example, solvent S at least can be by one of alcohol, water glycol, butyl carbitol, butyl cellosolve, terpinol structure
At.It is constituted that is, solvent S can be separately formed or be mixed by the substance listed.
Solvent S is evaporated when matrix 12 is hardened or dry or even dissipate while provides such as the matrix 12 of hardening
The hole (Pore) of the fine porous type of fine hair hole.To, matrix 12 can through hole supply noxious material to active carbon 11.
Micro-particle filler A is made of multiple particulates, is mixed in base together with active carbon 11 and solvent S as shown in Figure 1
Matter 12.Preferably, micro-particle filler A is made of soluble outstanding substance, and then can be easy to be mixed in matrix 12.Such as Fig. 2
(a) shown in, micro-particle filler A is adhered to the outer peripheral surface of active carbon 11, extracts and goes from matrix 12 after the hardening of matrix 12
Except micro-particle filler A.At this point, micro-particle filler A provides by bubble shape the outer peripheral surface of active carbon 11 as shown in Fig. 2 (b)
The stomata H that the hole of state is constituted.
That is, as shown in figure 12, stomata H generates the vacancy of micro-particle filler A by removing micro-particle filler A, in matrix
12 inside forms the subtle hole of air bubble-shaped, that is, forms subtle stomata offer for noxious material and be guided in 11 outer peripheral surface of active carbon
Channel.To, even if active carbon 11 is mixed in matrix 12, the adsorption area contacted with noxious material is expanded by stomata H,
That is specific surface area (exposed area), therefore improve 11 absorption property of active carbon.
Micro-particle filler A is the substance being made of liquid or liquefied gas, and or even Datong District identical as solvent S
The granularity of small difference, or with the granularity (be more than or less than) different from solvent S.Micro-particle filler A is identical as solvent S
It is evaporated when matrix 12 is hardened or dries or even micro-particle filler A can be extracted from matrix 12 while dissipation.Not with this
Together, it can also be mentioned from matrix 12 by other Extraction solvent (that is, contacting with reactant, passing through the chemical reaction with reactant)
Micro-particle filler A out.For example, micro-particle filler A at least can be by one of ammonia, freon or chlorine, nitrogen, carbon dioxide structure
At.That is, micro-particle filler A can be made of liquid and/or gasiform substance.
Here, above-mentioned stomata H is by the hole formation for the micro-particle filler A being made of particulate, therefore formation
The size for allowing gas (such as, air) to penetrate while matrix 12 for preventing water penetration from hardening.As a result, stomata H in fact to
The noxious material of the guidance gas form of active carbon 11.But stomata H can also be guided to active carbon 11 by steam morphosis
Liquid noxious material.
As a result, micro-particle filler A is following stomatal limiting value substance: providing subtle stomata, and be merely able to make sky by having
The particulate of the size for the subtle stomata that gas passes through is constituted, and micro-particle filler A is removed from the matrix of hardening 12, to base
Matter 12 provides subtle stomata.Then, as shown in Fig. 5 and Figure 14, the sheet material of coated shape is formed by printing technology in matrix 12
In the case where, ensure to breathe freely by the subtle hole formed by micro-particle filler A and solvent S and hole (subtle hole)
Property.
On the other hand, unmixed in the case where matrix 12 in micro-particle filler A, 11 outer peripheral surface of active carbon is by matrix 12
Isolation, only some is open by the hole of above-mentioned solvent S.But as shown in Fig. 12, in the sub- filler A of 12 hybrid fine particles of matrix
In the case where removing later, above-mentioned stomata H is formed in 11 outer peripheral surface of active carbon, therefore the case where compared to mixed solvent S more
Add and expands outer peripheral surface open area.As a result, in order to improve 11 absorption property of active carbon, most preferably mixed in matrix 12 micro-
Particle filler A.
On the other hand, adsorbent according to an embodiment of the present invention mixes 24 to 75 weight to the active carbon 11 of 100 parts by weight
The matrix 12 of part.The solvent S of 106 to 20 5 parts by weight is mixed for the active carbon 11 of 100 parts by weight.Work to 100 parts by weight
Property charcoal 11 mix 0.2 to 57 parts by weight micro-particle filler A.For this purpose, adsorbent be the active carbon 11 for mixing about 5 to 70wt%,
About 5 to 30wt% matrix 12, about 0.1 to 20wt% micro-particle filler A and residual solvent S are fabricated.Preferably,
Solvent S is constituted by about 37wt% to 72wt%.
If 11 content of active carbon can not expect desired adsorption capacity less than 5wt%；If exceeding 7 0wt%, not only
Reducing printing also reduces washing resistance.If 12 content of matrix reduces the bonding force with fabric less than 5wt%, therefore deposits
The washing resistance the problem of；If content exceed 30wt%, influence active carbon 11 specific surface area and active site and reduce
Adsorption capacity, therefore the matrix 12 of preferably mixing 5 to 30wt%.If micro-particle filler A less than 0.1wt%, can not expect to wish
The stomata H of prestige；If exceeding 20wt%, the viscosity of matrix 12 is improved, and then can reduce printing.If solvent S is insufficient
37wt% then excessively rapidly promotes the setting rate of matrix 12；If exceeding 72wt%, excessively extend the hardening speed of matrix 12
Degree.
On the other hand, above-mentioned adsorbent may also include additive, which according to circumstances adjusts the flowing of matrix 12
Property.For example, additive can be made of surfactant (including negative, positive, neutral ion).Additive raising is manufactured by adsorbent
At the printing of the coating agent of ink form, and the physical property for adjusting dispersibility, stability etc..Especially, additive mentions
The dispersing characteristic of high activity charcoal 11, and adjust the viscosity and mobility of matrix 12, so provide in keeping stability with

Also caused to reduce absorption property by the outer peripheral surface that matrix 12 covers active carbon 11.
The adsorbent of the embodiment of the present invention formed as described above respectively puts into solvent S, active carbon 11 in matrix 12
And it is mixed after micro-particle filler A by stirring to form the coating agent of liquid (such as, gel or colloid).This
When, adsorbent is mixed after can also adding above-mentioned additive.
As shown in Figure 1, coating agent is hardened after being coated on planar base 20, mention and then for the mistake of absorption noxious material
Filtering layer 10.That is, filter layer 10 is that basis includes above-mentioned active carbon 11 in coating agent and is formed in the above-mentioned of 20 surface of base
The adsorption layer of sheet form.Filter layer 10 leads to above-mentioned stomata H and hole, above-mentioned active carbon 11 adsorbs noxious material extremely, only makes
The air of purification restrictively passes through.To provide the suction being integrally formed on 20 surface of base with the filter layer 10 of thick film shape
Attached filter.That is, adsorption filter is made of the base 20 with filter layer 10.
Base 20 can be made of the fabric of breathable material or waterproof or grease proofing material.For example, base 20 can be by
Fabric, leather, synthetic fibers, sponge, non-woven fabrics, film, the film for forming multiple subtle air holes or mesh fabric are constituted.
Especially, base 20 is preferably made of the non-woven fabrics with gas permeability and light-type.
As shown in figure 3, filter layer 10 is configurable on the one side of base 20 or two sides is come according to desired absorption property
Filtering poisonous substance.If it is desired to the general absorption property of filter layer 10, then configure the one side in base 20 as shown in Fig. 2 (a), but
It is if it is desired to which stronger absorption property, then such as Fig. 2 (b) is shown can be in the configurating filtered layer 10 in the two sides of base 20.At this point, in base
It, can rapid filtering poisonous substance in two steps in the case where layer 20 two sides configurating filtered layer 10.
As described below, have while filter layer 10 removes above-mentioned micro-particle filler A by contacting with above-mentioned reactant
Above-mentioned porous type stomata H.Then, the solvent S for being evaporated by aftermentioned heat treatment process or drying or even dissipating above-mentioned, mistake
The hole (not shown) of the formation porous type of filtering layer 10.The hole and stomata H-shaped at pass the gas through base 20 and prevent water or
The size of moisture infiltration.If to 10 hole of filter layer and the noxious material of stomata H inflow gas shape, by being incorporated into matrix
12 11 filtering poisonous substance of active carbon.But even if the liquid noxious material of such as steam flows into filter layer 10
Portion, active carbon 11 can also be adsorbed and be filtered.
As shown in Figure 1, filter layer 10 forms the sheet form for having thickness thin, and matrix 12 as described above is by such as
The substance of polyurethane, silicon or resin is constituted, therefore has flexibility or even elasticity.
On the other hand, the coating agent being made of above-mentioned adsorbent is printed as thick film shape after being coated on 20 surface of base
Shape carries out hardening the coating agent by heat treatment later, forms filter layer 10 on the surface of base 20 accordingly with sheet form.
For example, filter layer 10 forms about 2 μm to 100 μm on 20 surface of base by silk-screen printing or intaglio printing etc.
Thickness.The thickness depends on the absorption property of printing characteristic and requirement.For example, if silk-screen printing filter layer 10, can print
About 5~100 μm or so of thickness then can print about 0.5~5 μm or so of thickness if intaglio printing filter layer 10.
For example, as shown in figure 5,100 may be printed by 100 mesh number net of polyester fiber if silk-screen printing filter layer 10
The silk-screen printing (plate-making, be not shown) of μ m thick, with the pressure of 3bar, the print speed printing speed of 100mm/s, 80 degree of Squeegee hardness,
The interval of 75 ° of blade angle, the plate-making of 3mm and substrate can be in the printing filter layer 10 of base 20.For this purpose, between printing screen
(face-to-face) configuration in compartment unoccupied place is on the top of base 20, later in the applying coating agent of printing screen top.Then, silk is printed
Netcom crosses scraper plate (not shown) and pressurizes and coating agent is unfolded, and coating agent is permeated to the lower part by the subtle mesh of silk screen accordingly, into
And it is transferred to the surface of base 20.To which filter layer 10 to be printed as to the shape of coating on the surface of base 20.
With above-mentioned difference, if intaglio printing, then by forming the intaglio printing plate of multiple fine recesses on one side (not
Show) printing surface filter layer 10 is printed as to the planar of thick film on the surface of base 20.For this purpose, above-mentioned coating agent coats
In the printing surface of intaglio printing plate, galley is arranged in face of being tightly attached to base 20 in the state of 20 top of base later
Pressurization galley, coating agent is transferred to the surface of base 20 accordingly.To which filter layer 10 is printed as applying on 20 surface of base
The shape of layer.
Base 20 is printed on densely with the state at interval while filter layer 10 forms point or grid or even oblique line shape
Surface.That is, can be in a part of the surface printing filter layer 10 of base 20.Especially, as shown in figure 15, if in base 20
Filter layer 10 is printed with space state in two sides, then filter layer is alternately printed in the state of can alternateing from 20 two sides of base
10.At this point, frame is as shown in Figure 15 (a) with mutual to enable filter layer 10 almost to filter the air through base 20
The two sides of base 20 can be respectively printed in the state of correspondence, it unlike this can also be in the one side in two sides as shown in Figure 15 (b)
The frame of printing is greater than the frame for being printed in another side slightly overlappingly to print filter layer.As described above, according to filter layer 10
It is alternately printed in 20 two sides of base, filters the noxious material of the gap inflow of Xiang Yi face interval in the another side of base 20,
Therefore in fact the noxious material of inflow can all be filtered.
By that (can be not shown, such as, ink-jet or 3D in the common printing machine of the printings such as textile fabric or film
Printer), in a face applying coating agent of base 20, filter layer 10 can also be printed as thick film shape accordingly.In this case
Under, filter layer 10 can be printed rapidly and critically.
Here, as shown in figure 4, above-mentioned filter layer 10 can also be printed in the surface of base 20 by spacer 10a.Such as
Shown in figure, spacer 10a forms convex shape on the surface of base 20 before forming coating agent (that is, filter layer 10).Such as figure
It is shown, multiple spacer 10a are formed, and the surface of base 20 is formed in the state at interval.
As shown, spacer 10a makes the surface interval of the printing screen SC for being tightly attached to base 20 and base 20.Then,
As shown in figure 5, spacer 10a penetrates the coating agent of printing screen SC by above method filling.That is, between coating agent is filled in
Every spacer 10a between gap.To determine the thickness of coating agent by the height of spacer 10a.
As a result, spacer 10a is the constituent element for increasing by 10 thickness of filter layer.In more detail, for above-mentioned
Screen printing mode, because the characteristic limitation of silk screen SC is printed in the thickness of the coating of base 20.But have as described above upper
In the case where stating spacer 10a, printing screen SC can increase the thickness of coating.Accordingly, if increasing coating by spacer 10a
Thickness, then thicker filter layer 10 can be formed on the surface of base 20.To which filter layer 10 may include more active carbons
11, micro-particle filler A and solvent S, therefore absorption property can be improved.That is, filter layer 10 forms more active carbons 11, gas
Hole H and hole, therefore expand the whole specific surface area of adsorption filter, hereby it is possible to more smooth filtering poisonous substance.
On the other hand, above-mentioned printing machine can also be used to replace above-mentioned printing screen SC come between being filled in coating agent
Between parting 10a.To which filter layer 10 is printed in rapidly and critically the surface of base 20 with thick film shape.
On the other hand, spacer 10a from the liquid phase-change material for being hardened to solid-like by constituting.For example, spacer
10a can be former by above-mentioned coating agent, liquid polyurethane, epoxy resin, nylon, acrylic acid or colloid or paste active carbon
Material is constituted.Base is coated on space state while spacer 10a has the height for being equivalent to 10 thickness of desired filter layer
Thus the surface of layer 20 forms convex shape on the surface of base 20.At this point, spacer 10a with put or mesh shape coat
In the surface of base 20, it can be interval in the surface of base 20 accordingly.Then, spacer 10a is hard by dry or heating
Change, is bonded to the surface of base 20 accordingly.
On the one hand, by the molding filter layer 10 of spacer 10a and the difference of diagram other can form multilayered structure.?
Under this case, by the mode of printing of above-mentioned spacer 10a in base's 20 surface printing, one layer of filter layer 10, Zhi Hou
This prints another layer of filter layer 10 again above with identical mode of printing, and then can form multiple filtration from 10.That is, in base
Surface first time molding filter layer 10 of the layer 20 after formation interval object 10a, in the table of the first time molding filter layer 10
Face successively forms another spacer 10a and second of molding filter layer 10 repeatedly, thus with the filter layer 10 of multilayer.According to
This, filter layer 10 forms multilayered structure, can more increase thickness, therefore also increase the content of active carbon 11 together.To lead to
The thickness for increasing filter layer 10 is crossed, whether there is or not the times of penetration of substance for delay, and then increase substantially absorption property.
For example, forming the filter layer 10 that a layer thickness is about 30 μm, about 200mm is about played2The absorption property of/g,
But in the case where forming three layers with this thickness, the pacts of three times is equivalent to because the thickness absorption property of three times also plays
The absorption property of 600mm2/g.Therefore, according to desired absorption property, the filter layer 10 of single layer or even multilayered structure can be formed.
Conclusion, filter layer 10 form multilayered structure by spacer 10a, can substantially increase thickness, pass through this thickness
Expansion, can significantly strengthen absorption property.
On the other hand, to condition of the filter layer 10 of base 20 at about 80 DEG C to 200 DEG C is printed in as described above, especially
It is under conditions of 120 to 180 DEG C, and the heat treatment of about 2 minutes to 25 minutes, especially 4 of progress minute to 15 minutes (adds

The solvent S that heat treatment process evaporates or dissipates above-mentioned.
It is cooled down at normal temperature as described above, filter layer 10 is placed after being heated, may filter that layer 10 can be stablized accordingly
Ground anchors at the surface of base 20.It can be but steady for tissue by water-cooled or the cold air rapid cooling filter layer 10
Qualitative and fixed stability preferably carries out Slow cooling by the way that air is cooling at normal temperature as described above.To,
Filter layer 10 is in fact laminated to base 20, forms a monolithic entity accordingly.That is, being provided by filter layer 10 and base 20
The adsorption filter constituted by one.
On the other hand, it is contacted according to cooling filter layer 10 with above-mentioned reactant, extract and removes above-mentioned adsorbent
Micro-particle filler A.For example, filter layer 10 by with above-mentioned ammonia, freon or chlorine, nitrogen, carbon dioxide chemical reaction with mention
The reactants such as degasser or the defoaming agent of these chemical components (solvent contact) are taken to remove micro-particle filler A.For this purpose, filtering
Layer 10 is precipitable can be cleaned in liquid reactant or by the liquid reactant.To by recycling micro-particle filler A
Reactant extract micro-particle filler A, above-mentioned stomata H is thus formed in 11 periphery of active carbon as shown in Figure 2.
Filter layer 10 removes reactant by drying after removing from reactant.But filter layer 10 is in addition to drying
Method in addition can also be by the removal reactant such as washing.
On the other hand, as shown in figure 13, above-mentioned spacer 10a can also form multilayered structure.As shown, at this
In the case of, it is interval in base 20 surface and forms spacer 10a for the first time, later by printing technology as described above to interval
Gap between filling coating agent carry out hardening form filter layer 10, on the surface of the filter layer 10 with the state second at interval
Secondary formation spacer 10a.Then, between the gap at second of the interval spacer 10a formed in the surface of filter layer 10 again
Filling coating agent is hardened.Filter layer 10 can form thicker thickness as a result, increase active carbon 11 accordingly, therefore improve
Absorption property.It is identical with this, it, can be easy to form if additional filling coating agent after making spacer 10a form multilayered structure
Thicker filter layer 10 is to form desired thickness.
On the other hand, as shown in fig. 7, above-mentioned base 20 can be by noxious material protective garment (such as, chemical protecting suit)
Outer shell fabric (OT) is constituted.That is, filter layer 10 may be provided at outer shell fabric (OT) as shown in the figure.At this point, as shown, it is preferred that
It is printed in the inside of outer shell fabric (OT) for filter layer 10, is integrally formed with the surface of outer shell fabric (OT).The outer shell fabric
(OT) can be constituted by being not easy ventilative fabric, such as kevlar fabric, and preferably by can waterproof and it is grease proofing while

That is, noxious material protective garment can be manufactured by above-mentioned adsorption filter.
As described above, manufacture utilizes the adsorption filter system being made of base 20 and filter layer 10 by various modes
It makes protection wearing fabric and is tested, test result is as shown in figure 9, in test by active carbon, adhesive and filler
It mixes and is tested with residual solvent.As shown, for the face of the adsorption filter with the embodiments of the present invention
Material, constitutes embodiment 1 to 15 by the adsorption filter being made of various ratio of components and is tested, and measure washing
Adsorption capacity before and later.Then, the prior art 1 for being applicable in beaded activated carbon that will be referred in the prior art
The prior art 2 (Fig. 9) of (Fig. 9) and simple sprinkling active carbon powder is also tested together as comparative example.At this point,
Since practical chemical agent can not be applicable in for each fabric, using with the molecular structure similar with the chemical agent
And the similar medicament of attribute, and liquid-phase assay method is used, protective performance is evaluated.For example, for similar
Medicament has used DMMP (Dimethyl methylphosphonate, the methylphosphine of the similar products phosphorous (P) of Suo Man (G D)
Dimethyl phthalate) benzenethiol (Thiophenol) with the similar products sulfur-bearing (S) of mustard (HD).Then, as shown in Fig. 10,
Each fabric (sample of sorbent) is exposed to (impregnate or sprinkling) similar medicament (sample liquid) when experiment, setting when
Between during be adsorbed with noxious material, absorption property is measured as unit of the time later.Then, GC/UV/Vis is used
Spectroscopy (gas chromatography/ultraviolet/visible absorption spectra) analyzes each fabric, is substituted into later based on analysis data
Residual concentration is calculated in calibration curve, and then calculates the adsorption capacity of filter layer (adsorbent).
The test experiments of scourability are to fill each fabric (washings) of specific detergent and 45kg shown in Figure 11
Divide and washed for the first time after being soaked in 32~43 DEG C of water 4~6 minutes, cleans 2 for the second time in the same way again later
Minute, it is soaked in 32~34 DEG C of water later and implements rinsing 2 minutes for the first time, rinse the again in the same way later
Secondary and third time, it is 35~50 minutes dry at 19 DEG C after being then dehydrated 3~5 minutes, after test washing later
Adsorption capacity.
As shown in Figure 9 test result is as follows: the case where embodiment 1, washing fastness is outstanding, but active carbon 11 is mixed
Resultant is insufficient, thus has no adsorption capacity before washing and later, does not have absorption property accordingly；2 feelings of embodiment
Thus condition is not only unable to fully to form the thickness of adsorption layer because low viscosity causes printing unqualified, also reduction washing fastness；
The case where embodiment 3, washing fastness is outstanding, but can not form stomata H in the outer peripheral surface of active carbon 11, therefore can not be maximum
The specific surface area for ensuring active carbon 11 of limit, therefore reduce absorption property.The case where embodiment 4, compared to 11 base of active carbon
The ratio of matter 12 is unqualified, therefore washing resistance is outstanding, but due to the amount of active carbon 11 deficiency, lacks adsorptivity
Energy；The case where embodiment 5 and 6, determines that the content of the matrix 12 of cleaning durability is abundant, it is ensured that washing fastness, still
The ratio of active carbon 11 and micro-particle filler A are insufficient, therefore there are problems that printing.It is the case where embodiment 7 to 10, fixed true
The content of the matrix 12 of washing resistance is protected, the composition of active carbon 11 and micro-particle filler A is changed, and then improves printing
With absorption property.Embodiment 11 and the case where 13, in order to ensure more absorption properties, compared to the content of active carbon 11
The content of matrix 12 is excessively reduced, and then improves absorption property, but embodies the tendency for reducing washing resistance；Embodiment
12 the case where, the mixing ratio of active carbon 11, matrix 12 and micro-particle filler A are suitably formed, and then before having played washing,
The adsorption capacity that absorption property afterwards requires.Then, the case where above-described embodiment, by extracting micro-particle filler A in active carbon
11 outer peripheral surface ensures the specific surface area of active carbon 11 to the maximum extent while forming stomata H, more improve adsorbed accordingly
The absorption property of filter.In addition, increasing the thickness of filter layer 10 by spacer 10a, it is increased by containing for active carbon 11 naturally
Amount, more improves absorption property accordingly.Meanwhile in the case where constituting multiple filter layers 10, absorption property is further enhanced.
Here, as shown in figure 9,1 (comparative example) compared with the prior art, the specific surface area of embodiment 12 is smaller, but inhale
Attached excellent performance.Its reason is as follows: the prior art 1 is that activated carbon beads form spherical shape, therefore large specific surface area, but because ball
The shape feature of shape, noxious material be by the outer peripheral surface of active carbon strain, therefore it is low compared to specific surface area absorption property.Phase
Instead, embodiment 12 is to form planar, directly face-to-face with noxious material, even if therefore specific surface area it is small, but absorption property ratio
The prior art 1 is outstanding.On the contrary, the case where prior art 2, the adsorption capacity before confirming cleaning is outstanding, but in washing
Active carbon all falls off, and loses absorption property accordingly.
Accordingly, it is expressly understood that in the adsorbent and its adsorption filter of the embodiment of the present invention by testing with most appropriate
Ratio mixed active charcoal 11, in the case where matrix 12 and micro-particle filler A, provided compared to comparative example more outstanding
Absorption property.As a result, by the adsorbent and its adsorption filter of the invention with above structure, adequate relief is Viability
Charcoal 11 improves the absorption property of noxious material, and the fabric that active carbon does not fall off, and then polluted in cleaning in washing
It can be recycled later.
In addition, adsorbent is made of Powdered Activated Carbon 11, matrix 12, solvent and micro-particle filler A, it is ensured that appropriate
Viscosity, therefore it is not only easy printing, but also provide outstanding processability when manufacturing fabric, and solidification is in blocks after curing
When material shape, it is ensured that elastic force, therefore as the protective garment for having serious fold outer shell fabric (OT) or liner (IN) use
In the case where, outstanding sense comfortable and easy to wear and preferred durability can not only be provided, and almost permanently prevent active carbon
1 falls off.
On the other hand, as shown in figure 14, the above-mentioned filter layer 10 being made of the sheet material of coating morphology can be in base 20
Surface forms round perhaps elliptical shape and can also form the polygonals such as triangle, quadrangle, five jiaos or hexagonal unlike this
Shape.At this point, above-mentioned spacer 10a forms the circular state for being formed simultaneously interval as shown in the figure, and in spacer 10a
Between fill coating agent, filter layer 10 can form shape as described above accordingly.As shown, the filter layer 10 is with equidistant
It is interval in the surface of base 20.So that multiple filter layers 10 are formed, by the gap at interval (that is, passing through the gap being spaced
Base 20) it ventilates.
As shown in figure 16, it forms structure as described above and in one side there is the base 20 of filter layer 10 shape is laminated
At multilayered structure, and then filter the noxious material into the air that the gap at the interval of filter layer 10 is circulated.At this point, such as Figure 16
(b) shown in, multiple bases 20 constitute alternating state with the stacking of filter layer 10.The air to circulate as a result, from the base 20 on top is logical
Cross the 10 filtering poisonous substance of filter layer being arranged in bottom substrate 20.For the base 20 of such laminated arrangement, due to filtering
The gap ventilating air at the interval of layer 10, therefore filter layer 10 is set compared in whole surface, it can more improve gas permeability.
That is, adsorption filter as described above improves gas permeability.Certainly, it is possible to provide the adsorption filter is as above-mentioned outer layer surface
Expect that (OT), liner (IN) or middle layer (MD) are obvious.
