Abstract

This invention provides a forming method and structure to interlace compound filtration materials by using airflows. The short fibers and functional micro-particles are delivered to a compound air-spraying device by their feeding-air flows respectively. The feeding-air flows of the short fibers and the functional micro-particles enter into the diffusing-and-mixing transmission area where the two feeding-flows are mixed. The mixed feeding-flow diffuses downwardly, and flows into a flow-guiding device so that the airflow will steadily transmits to the multi-layer compound forming area underneath. The short fibers and the micro-particles are sucked by a sucking device located under multi-layer compound forming area so as to stick and stack on a pattern web and to form a filtration material in multi-layer structure, from low density to high density gradually. The filtration materials are then heated for shaping, and cooled down to its final form. By this method, the filtration material at its final form is a multi-layer interlaced compound structure consisting of a protecting-layer in the bottom, an adhering-layer in the middle, and a uniform-flow layer at the top.

Description

1260993 V. INSTRUCTION DESCRIPTION (1) [Technical Field] The present invention relates to a technique for forming a composite structural coffin by using a gas-dynamic interlaced composite fiber and functional particulate matter. [Prior Art] According to the application of chemical pollution protection filter material There are many mature technologies in the field, in which the loading of functional particulate matter 1 such as activated carbon into the fiber web is the mainstream of the technology. There have been many inventions describing the production techniques of such filter media, such as: US Patent Nos. 4, 795 5 1 6 68, Krueger eta 1 · 4, 8 6 8 , 032 by Eian et a 1· 5 5丨486, 410 by Groeger et a 1. The proposed fabric structure contains immobilized functional particulate matter and other related technologies, which are mainly applied to the production process of adsorption materials, with fibers as adhesives, The functional particulate matter is ablated in the fiber structure, and the transitional air or liquid causes the toxic pollutants to be adsorbed by the functional particles to achieve the protection of the filtration. The prior art has the use of melt-blown method (Μel t-B1). Own) The netizer then adds functional particulate matter, such as activated carbon, to the process to adhere it to the me 11-b1 own web structure. Therefore, the pressure drop of the filter produced by the method is not effective and can not be effectively applied to the production of high-micron content filter materials. Moreover, the me 11 -b 1 own fiber is small, and the uniformity and stability of the cotton net structure are poor, which may cause the displacement or even the loss of the functional micro-grainous substance during subsequent processing and application. And the patent published by Groeger e t a 1 ·> which is composed of a composite fiber type IUI tl.m 1 JUI \»J Ι.1Λ1.ΙΙ juiuk u is a carrier, and the functional micro-grain is fixed to the fiber.

IHl 1260993 V. INSTRUCTIONS (2) --- ^ In the hole, the subsequent layer-by-layer stacking is used to achieve the content of high particulate matter, and the stability of the functional particulate matter in the filter material structure is increased, so that it is not processed. In the application, the loss of loss, and the production of high content of functional particulate matter of the filter material, such as: activated carbon in chemical adsorption protection, the use of aging is invisible. However, the three-dimensional structure of the fiber web is used as a carrier, and the functional particulate matter is adhered or fixed in the structure. Although a certain functionality can be achieved, the structure can only be limited due to the predetermined type of the carrier. Presented in a single fixed form. The increase in the content of functional particulate matter, while contributing to the increase in service life, does not contribute much to substantial adsorption or filtration efficiency. In addition, the prior art mechanically fabricates the fibers into a three-dimensional network structure, and then uses the pore space between the fibers to place the particulate matter. In the process, the size and shape of the functional particulate matter are different. The size of the pores is also different. It is not easy to control the density uniformity of the structure. Therefore, many pores are not filled with functional particulate matter, which leads to the least resistance to airflow or liquid passage. Causes a channeling effect. In contrast, the phenomenon that the source molecules cannot be captured by the functional particulate matter is also a factor of inefficiency, especially when the layers are laminated, because the fiber structure cannot withstand the weight of the particulate matter. The collapse of the structure is a defect in the density of the structure, resulting in poor quality of the filter material. At the same time, it is necessary to control the thickness of the fiber and the appearance and size of the particulate matter to achieve an appropriate combination and uniform structural density.

1260993 i, invention description (3) not available. Because of the rabbit, & first to use the fiber three-dimensional structure as a carrier, the structure of the structure has been restricted, and it is impossible to control the variability. Ning functional filter material, such as: adsorption filter material, in the fiber structure & τ Χ ^ ', in addition to the addition of functional particulate matter, must also take into account the efficiency of suction 2 and the life of use, so in the structure In addition to the stability, it is necessary to control the variability of the structure, such as: fiber fineness and particulate matter 1 liter / ^ size combination structure bulk density uniformity and create a non-linear W road 'increased pollution source The residence time in the filter material increases the probability of contact with functional substances, so that the function and efficiency of the filter material can be improved, and the purpose of chemical dyeing prevention and control can be effectively achieved, and the application field is also wider. [Contents] The main purpose of the present invention is to use gas power as the main key, and supplemented by special heat treatment methods. And based on the short-fiber (sh〇rt-cut f 1 ber) and functional particulate matter (such as activated carbon, potassium permanganate impregnation, chemical adsorption polymer, etc.) The stable gas flow simultaneously disperses mixing, interlacing, and composite molding, thereby producing a gas-dynamic interlacing composite molding technology of a sheet-like non-woven type chemical protective filter material. According to still another object of the present invention, on the basis of gas power, fibers and particulate matter can be intertwined and composited at the same time, instead of dispersing and bulk density of the precursor material as a result of stabilizing the gas flow. , can achieve a very uniform effect, and the two substances are intertwined and fixed, so 'structure stability is high, and the airflow is dispersed and mixed, and finally transmitted. Page 7 1260993 V. Invention Description (4) Accumulation, control two The mixing ratio of the materials, and the particulate matter is formed into a composite at the same time from the low content to the ambiguous inclusion, and does not need to be achieved by the layered abundance method, and the bulk density uniformity is still very good, Will cause any structural defects. Another object of the present invention is to form a three-layer structure in which a single filter material is simultaneously formed by airflow dynamics molding due to a change in airflow force, and simultaneously control the ratio of the three-layer structure to each other. Optimal airflow resistance and chemisorption efficiency. The change of fiber fineness matches the size of the selected materials, and the same is true for the dynamic shaping of the airflow;;;: = airflow resistance and the residence time, which increases the efficiency relatively, so the control of structural change factors is quite high. The quality control is also good. When the filter material is adsorbed by the fiber, if the molecule is removed, the surface of the fiber body is increased, and the other surface of the invention is formed by the combination of the surface and the work material. If the particle is closer to the special hot surface for capturing and adsorbing, it is melted. The purpose of the phase structure is to stabilize the medium fiber body and the particle, and the gas structure is uniform. For the formation of the gas energy particulate matter: the activated carbon filter material, the probability of adsorbing the substance (activated carbon) is relatively improved. After molding, it adheres to the functional fine particles, so the heat resistance is also improved. The other interface of the aggregate interface is due to the interface of the material, because the microflow passes through the uniform resistance, that is, the probability of the interface is uniform. However, when the pollution source airflow passes through the surface, the chemical pollution is caused by the heat treatment of the molded filter material of the present invention, and the surface of the filter material is adhered. Contraction and compaction, and steric obstacles between fibrous materials

Page 8 1260993 V. INSTRUCTIONS (5) The flow path formed by the three-dimensional spatial structure of the filter material structure is a non-linear irregularity caused by the inability to move the hole to cause the pore to expand and form a specific flow path of the polluted air flow. The route, in this way, not only causes the chemical pollution molecules to pass mainly through the surface of the functional particulate matter, the contact probability increases, and the residence time in the filter material structure increases, thereby increasing the capture adsorption time and greatly improving the overall efficiency. [Implementation Method] As shown in the first and second figures, the steps of the present invention include: (a) respectively sending the short fibers (1) and the functional particulate matter (2) to a composite gas blowing device by using a gas stream. (3), and the feed airflow of the particulate matter (2) is disposed in the middle of the composite gas blowing device (3), where the air blowing device (3)$ functions as a blowing device, but its shape is not limited to a circular shape. The preferred embodiment is a rectangular parallelepiped body, so that the air vents are in a narrow state, so that the feeding airflow of the two can simultaneously enter the diffusion mixing transfer zone (4), so that the mixed feeding airflow drives the short fibers and the particulate matter. Diffusion from top to bottom, and flow through a flow-through device (42) 'to make the airflow stably transmitted to the lower multi-layer composite molding zone (5) ^ (b) using the suction provided under the multi-layer composite molding zone (5) The gas device (51), the short fiber (1) and the particulate matter (2) are sequentially adsorbed and stacked on a forming net (52), and the inhalation amount of the getter device (51) is adjusted according to requirements. It is balanced with the mixed feed gas stream (41) to form a three-layer layer on the moving forming web/ The structure of the filter layer (8) *

1260993 5. Invention description (6), between; at this time, a suction device (62) can be continuously sucked under the filter material (8); and (d) the heat-set filter material (8) is sent to the cooling zone. (7); At this time, the inhaler can be continuously lowered by a suction device (71) while cooling. Further, the functional particulate matter (2) may be an activated carbon or a potassium permanganate impregnated alumina or a chemisorbed polymer. Further, the diffused mixed transfer zone (4) is a box having a downward opening = a container (43), and a flow guiding device (42) provided therein is composed of a plurality of baffles. - by means of the above-mentioned technical means, the feed stream (11) of the short fibers (1) passes through a complex gas blowing device (3) where it merges with the feed gas stream (2 1) of the functional particulate matter (2) The functional particulate matter (2) can be fed by a certain amount of feed. After the quantitative feed, the feed gas stream (21) is used to enter the composite gas = worm (3), and then the mixture of the two substances is fed into the gas stream ( 41) Simultaneously entering the diffusion mixing zone (4), due to the flow velocity and accumulation of the airflow leaving the air blowing device, causing turbulence (tUrbulenCe), thereby making the staple fiber, (1) and functional particulate matter (2) Interdiffusion mixing, followed by a special flow guiding device (42), t gas flow (41) composite forming zone (5).夕增 = In the diffusion mixing transfer zone (4), due to the composite gas blowing device (3) 2, =, two distinct airflow regions can be created, as shown in the third figure: A, right (A1), (A3) ) is mainly the fiber area, and the middle (A2): is the area covered by the mixture of activated carbon and carbon, and this phenomenon becomes a distinct substructure with the composite gas blowing device (3)

Page 10 1260993 V. INSTRUCTIONS (7) The outlet design is adjustable, so it can be simultaneously, (A 2 ), (A 3 ) are proportional to each other, and then the visual demand can be adjusted to meet the requirements of the mixed airflow. The flow device (4 2 ) is mainly used at this stage by means of the suction device (5 1 ) (2) stacked in a moving forming wire (52), which is moved forward by the conveying device (53), and the gas volume and feeding are carried out. The airflow (4 1 ) reaches equilibrium, that is, in the case of a difference in the flow rate, such as insufficient intake, the feed gas (1) and the functional particulate matter (2) are blown away without affecting the diffusion mixing zone (4). The material has not been mixed and interlaced uniformly and rapidly formed, 'so in the molding, when the suction device (51) is formed, the three gases formed during the diffusion mixing are formed on the molding mesh (5 2 ) at the same time, such as the third As shown in the figure, the stage (丨) is a continuous movement of the underlying forming fabric (52), so that the fibers (1) are interlaced with the particulate matter (2), and the aggregates are further deposited thereon, initially forming three during molding. , the three stages are all in the same 4 1) short fiber and particulate matter 2) The mixed transmission uses the suction device (5 1) to operate the feed airflow (41) f in a steady state. The main key of the gas flow stabilization through gas dynamic molding is to control the area of the two regions (Ai). The surface structure will be the desired filter material structure. After that, the molding process is carried out, and the short fibers (1) and the particulate matter are formed on the side, and the forming mesh (52) is used to adjust the suction device (51) to adjust the sides of the suction molding surface without causing airflow (4 1) instead. Short fiber method molding, such as the conveying speed of excessive suction, is easy to adjust the structural uniformity of the two kinds of broken filter materials. In the flow zone (Al), (A2), a three-stage shaped fiber is formed into a stack, and due to the entry stage (I I ), it is a functional filter material of the fiber layer structure of the short final stage (I I I ). Time is carried out, the feed airflow (sent to the forming wire (5 2 ), and then excluded, the entire process airflow is over the formed structure. To control, the initial filtration after molding

Page 11 V. Invention Description (8) Material (8) 'The cross-sectional structure is as shown in the third figure. The filter material (8) presents a distinct layered three-dimensional structure, which contains: and anti-δ vine layer (8 1 ) 'The system is located at the bottom of the formed coffin, with short fibers (1) as the main constituents, and presents a densely packed state; and the attached layer (8 2 )' is located above the protective layer, with functional particles The substance (2) is the main component, and is uniformly interwoven with the short fibers to form a body structure, wherein the bulk density of the functional particulate matter is relatively sparse, and the pore density of the short fiber aggregate after heat setting is relatively dense. a non-linear airflow passage (8 4 ) is formed at an interface between the short fibers and the surface of the functional particulate matter; and a current equalization layer (83) is located above the adsorption layer (82), and is made of staple fiber, 隹 (1) ) is the main component' and presents a state of looser accumulation. This layered structure is mentioned in the above description because the short fibers (丨) and the particulate matter (2) form three flow dividing regions (A1), (A2), (A3) in the diffusion mixing transfer zone (4). When the short fiber (丨) and the particulate matter (2) are mixed and fed into the gas stream (41) and stacked, the fiber region (1) on the left side is first formed on the forming wire (52), and then thereon. In the middle of the forming wire (52), the short fibers and the particulate matter (2) are interlaced and stacked thereon, because the bottom has been formed into a network assembly to prevent the particulate matter (2) from being carried away by the airflow at this time. Μ short fiber (1) and particulate matter (2) "woven mixed aggregate can be ΐ 1 35, · after 9 to the right forming area (π 1), the fiber is re-stacked, formed on the upper part of the filter material, where the air forming stage is completed. t This stage' The present invention mainly utilizes aerodynamic molding, which not only achieves the purpose of simultaneously stacking and interlacing short fibers (1) and particulate matter (7), and

Page 12 1260993 V. INSTRUCTIONS (9) The filter medium (8) has a three-layered steric density which also produces a layered effect phase (1) when the feed stream (4 1 ) is in very short fibers ( 1), and the first accumulation is thinner's. Therefore, the flow density in this region is high, and the structure is dense, and the three-dimensional structure of the short 'short fiber aggregates also forms a protective layer (8丨) structure. When stacked on the protective layer (8 1 ), the flow velocity is relatively reduced within the structure, and (2) uniformly interlaced with each other, so that the composite structure density is less than the protective twist, and the filter material is formed (8). The adsorption layer (82), while the aerodynamically shaped interlaced stacks are filled with each other to make the density uniform, without structural defects, the thickness of the overall filter material gradually increases, and finally to the right of the forming zone ^ (1 shunt area (A 3) The short fiber transport molding is formed at the lowest velocity of the gas flow rate in the forming zone, which results in the lowest stratosphere (83) of the fiber J stack. The structure and the accumulation of the three-layer structure. As shown in the third figure, only the dispersed type is formed on the forming wire (52) in the forming splitting zone (A1), and the stacking thickness is relatively high, so that the pores between the short fiber fibers are relatively small, and The gas flow is stable and uniform, and the pure fiber collection of the layer (81) is gradually increased as the short fiber and the particulate matter are interlaced in the stack thickness, and the short air fiber (1) is simultaneously different from the appearance of the particulate matter substance. The main adsorption function area in the middle of the body structure, that is, the structure density of the short fibers and the particulate matter are uniform at the same time, and the two holes are dispersed. At this time, 'therefore, the resistance to the air flow is relatively Π) the short fiber feeding airflow ( 41) on the adsorption genus (8 2 ), the resistance is large, so the flow velocity is uniform and uniform through the structural density, and the pores forming the filter material are relatively large, but the uniformity is as described above for the functional particulate matter and activated carbon. For the filter material, when the filter material

1260993 V. INSTRUCTIONS (10) When the structure has a layered structure that is sparse and sloppy, its adsorption efficiency will be superior to that of a single filter and a material structure. When a polluted source gas flows through the filter material, its gas flow direction is as shown by F ig · 4 , and enters by the stratosphere ( 8 3 ). When the protective layer (8 1 ) flows out, the stereostructure of the stratosphere (8 1 ) is sparse. When the airflow passes through the fiber (丨) aggregate, it will be uniformly dispersed, so increasing the pollution source through the area of the activated carbon adsorption layer (8 2 ) respectively, the diffusion source gas flow is uniformly diffused into the activated carbon fiber interlaced layer' as the thickness of the filter material increases. At the same time, the flow velocity is also lowered by diffusion and resistance, which increases the residence time of the contaminating molecules, and is adsorbed by the activated carbon (2) at the same time, and the protective layer (8 1 ) of the filter material (8) is a short fiber (丨) aggregate. The stacking structure is denser and has the greatest resistance to the airflow, so the residence time of the polluted airflow to the adsorbent layer (82) can be relatively controlled. In the design of the composite gas blowing device (3), the area ratio of the airflow splitting regions (Αι), (A2), and (A3) can be adjusted, and the layered stacking of the crossing structure can be controlled relatively. The thickness ratio is adjusted according to the conditions required to actually filter the adsorption source, and the optimum efficiency is used to meet the needs of the customer. That is, when the deposition thickness of the protective layer (8 1 ) is higher, the overall flow (the air flow) The resistance south's retention time of the pollution molecules is also lengthened, and the adsorption effect is added, and vice versa. 曰In addition, the 'flowing layer structure (83) and the protective layer (81) sandwich the adsorption layer (82) in the middle, which can prevent The movement or detachment of the activated carbon particles (2): while the short fibers of the adsorption layer (82) and the activated carbon (2) simultaneously form a cross-section; the stereostructure can also prevent the displacement of the activated carbon particles from detaching, so the whole ς) The structure has high stability after molding and the uniformity is also good. In the filter material, the mixing ratio of short fiber and activated carbon can also be controlled in the process.

Page 14 1260993 -------- —— V. Description of the invention (Η) In this invention, the controllable relative carbon content of the activated carbon content can also be controlled to maintain a certain uniformity in this range. Degree, but compared with the general practical adsorption filtration application, the good content is between 60% and 90%, and the fiber content of the filter material (8) is between 15% and 40%. The filter material process can be from low weight l〇〇g/m2 to high weight type 1 'without the use of layers and lamination to achieve high gas-powered composite molding technology, the ratio of each, and the basis weight change, The adjusted control has a high development value after one molding and no need to pass through. In addition, the basis weight of P welcoming materials can be changed (the Danny number) and the above-mentioned uniform structure of the size of the activated carbon particles, and the stability is high, and when the three-dimensional structure of the fiber web is added to the activity, the fiber diameter is If the pores are large and the pores are formed in the pores between the fibers, the particles must also be lightened. If the weight is equal, the number of equal particles must be relatively reduced, thus causing the activity of the active attachment to be greatly reduced. If the fiber diameter reduction number must be increased, the pores of the three-dimensional network junction can be formed to be smaller, which results in a poor stability of the structure in the pores between the active charcoal particles, and the activity is in the range of 10% to 90%. The structure and the structure of the two substances with high or low content, so that the overall performance of the activated carbon is the best after the test, relative to the overall basis weight change, with this, 200g / m2 can simultaneously become a high or high content . Because it is possible to control the composition at the same time, it can be completed in the process at the same time. Because of the choice of mutual composite like other carbon, when the hole is also large, because of the carbon distribution of the material, the mono-structure, such as the carbon-free The fiber is not dissipated differently, and the process is still based on the basis weight of the material. If the active carbon is accumulated, the area of the active and non-uniform areas will be uniform and high, and the dimensional diameter can be achieved after forming. Light or thin activated carbon, the unitary carbon is even, and the fiber is interfibered into the fiber.

Page 15 1260993 V. INSTRUCTIONS (12) Poor adsorption functionality. However, the fiber (1) and the activated carbon (2) described in the present invention are mixed, and the power of the A body is simultaneously described as a short-term defect because the two materials are simultaneously interwoven, and the size of the active carbon particles is small because of the two processes of 5 How to change, mouth Z regardless of the fiber diameter is made = high, structural stability is high; with the appropriate 'can be woven part to achieve, that is, the adsorption layer (8, = mixed with activated carbon mixed and stacked into jujube ,) The two substances are dispersed in the airflow, accumulating i due to the appearance of the two substances. The three-dimensional makeup is not the same. The flow in the corpse is different. The accumulation, the opening/shape is different, and the gas (7) is a three-dimensional irregularity. Airflow molding. Activated carbon granules cause obstacles in the process of occlusion, and the intergranularity is large. For example, the pore space between the FU particles (2) is equivalent to the pore space created by the activated carbon (2). When the tempering force is passed, the hole is formed into a mouth: although == Λ Λ J J Λ , 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型 成型The combination of the two-party activated carbon particle blocking factor 'is stacked to form fiber rafts. : The structure (1), which in turn makes the overall airflow resistance average, through Κ (1) 盥, -, relative to the structure of the adsorption layer of the filter material after molding, and the staple fiber: , such as c (2) uniform sentence is interwoven into bulk density The three-dimensional structure of the sentence. .., mainly by the gas power & type of factor can achieve this gas circulation activated carbon due to staple fiber

Page 16 is obsolete and i short fiber (1) is mixed with activated carbon (2). When the surface is due to the steric obstacle of activated carbon (2), the airflow part & Passing through the fiber assembly (i), 1260993 V. Description of the invention (13) The dimensionality of the aggregate (1) is uniform, and the gas and the six stacking enthalpy are formed by gas dynamics, so the tight resistance is low. F and uniform force and the gas flow caused by the activated carbon particles (2) is adsorbed and filtered from the short fibers, so that when the polluting molecules are connected in series, it is easy to make, and -1) pass through the 'while fiber' The aggregates between the aggregates are not able to be pinched - the knife directly runs through the coffin (8), and the activated carbon (2) is evaluated for its effectiveness. For this reason, the structure of the y contact will form a non-linear flow path and increase the relationship with the surface of the activated carbon, which is the main key point of the functionality of the activated carbon adsorption filter. However, there is no mention in the present invention. To achieve the relevant process technology of this structure, the short-fiber only composite molding technology is 'first gas-driven, the precondition is the one-size carbon (2) uniformly dispersed and intertwined to form the body structure and then the shaping There is an absolute high degree of uniformity between the two, when the formed filter material is given a special heat treatment, shown in Fig. 2.

Performance. When hot

Page 17 1260993 V. INSTRUCTIONS (14) The heat of leaving the material after the removal of the material is also continuously formed from a suction to a heat treatment to a dense and dense three-dimensional structure, and when the surface of the staple fiber is melted and melted, After the short fiber short fiber and the short fiber, the filter material (8) is greatly improved, and the fiber is good, relatively processed, the heat treatment will not make the main energy of regeneration, and it is necessary to use any adhesive for retaining activated carbon. It is coated with the dry agent and has a performance south. When heat treatment, the fibers with short pores between the particles cause the structural density of the fibers and fibers to tend to (1) and the surface of the particles (2). When the fibers of the activated carbon particles (2) shrink to form a large processing chamber, they are immediately inserted ( 71) Continuous suction down during the cooling coiling process, the 〇 (1) is heat treated, and the fibers begin to produce a bond between the dimension (1) and the tongue carbon (2), and the same effect of the fiber , it still retains its softness and goodness. On the other hand, its surface melts or shrinks, so it can give the activated carbon better adsorption performance, and strengthen the structure. It will not absorb the external surface area and heat up to shrink the fiber. (1) The pores in the shrinkage interface are narrowed and dense, and the interfacial pores between the gas flows are not shrinking, and because of the scale displacement, the cooling zone is still retained and the gas is cooled, mainly to ensure the consistency of the structural structure. That is, when the temperature of the softening point is reached, the phenomenon of heat shrinkage, the surface of the surface adheres to each other, and shrinks at the same time, so the structural strength and stability of the heat are made so that the filterable material can be disturbed, and the activated carbon 2) However, the heat is desorbed by the activated carbon to dehumidify and reactivate. This bonding method is used to prevent the activated carbon (2) surface from being adsorbed on the activated carbon (2) relative to the adsorbent material, such as Fig5. Fig. 7 shows that the fiber assembly (1) has a larger overall resistance, while the short fiber 'is because the steric obstacle of the fiber shrinkage is not due to its pore size, so

V. INSTRUCTIONS (15) The pores between the short fibers (1) and the surface of the activated carbon (2) increase, and the structure here tends to be loose. This phenomenon can be seen by an enlarged schematic view of the F i g · 7 filter material. Therefore, when the chemically contaminated gas stream passes through the activated carbon adsorption filter material, it is caused by the activity of the broken (2) and the shrinkage of the fiber aggregate (1), and the pore between the fiber and the living surface is mainly the flow channel ( 8 4) Through the filter material, the probability of contact between the contaminating molecules in the gas stream and the surface of the activated carbon is relatively increased, and the adsorption efficiency is greatly improved, which is superior to other activated carbon filter materials. And because the filter material structure is a three-dimensional spatial three-dimensional structure, the flow channel (8 4 ) generated thereby is a non-linear curved flow path, increasing the residence time of the air flow through the filter material, so that the time for the activated carbon to adsorb the contaminating molecules increases. It also enhances the overall functionality of the filter media. In view of the above, the present invention is characterized in that a gas-powered interwoven fiber and a functional micro-phase mussel (live carbon) are formed into a three-layer structure filter material technology, and not only can be prepared and a highly functional adsorption filter material. And with special heat treatment, d, material produces key structure, enhances adsorption efficiency, and yield and variability is better than other adsorbent coffins.
