Description
Technical field
The invention belongs to a kind of senior weaving face fabric technical field, relate to a kind of composite material fabric, especially relate to a kind of netted multi-layered type electromagnetic radiation composite material fabric.
Background technology
Wireless device brings great convenience for people's life, and the thing followed also has various electromagnetic increases, has brought a lot of puzzlements to people's life; Or even dangerous, therefore various screen methods also arise at the historic moment, and have many fabrics aspect shielding, to play certain effect; Yet; These fabrics all are to give function of shielding from the raw material aspect earlier, to spinning and weaving and bring certain inadaptability, influence production efficiency.
The manufacturing approach of high-performance electromagnetic wave shielding fabric in the caused by spinning industrial production, product can be widely used in industrial fields such as family expenses and military project, scientific research, workers and peasants doctor, are used for shielding and protection to unwanted electromagnetic wave.
Electromagnetic wave is the another big pollution sources after air pollution, water pollution, noise pollution.Electromagnetic wave not only is detrimental to health, and also jeopardizes the running of instrument and equipment.In military field and communication field, electromagnetic leakage also can cause and divulge a secret.Electromagnetic wave screen fabric is commonly used to make military targets such as dummy ship that military shielding tent, drop cloth and military training use, target flag, target umbrella, and therefore, the research and development of high-performance electromagnetic wave shielding fabric have obtained the attention of height.
Existing electromagnetic wave screen fabric comprises wire cloth, and wire and textile yarn interweave or the embedding woven fabric, the blended fabric of metallic fiber or carbon fiber and conventional textile fabric, plating, chemical plating, vacuum metallization film fabric.Above-mentioned several kinds of electromagnetic wave screen fabrics respectively have pluses and minuses, and wherein wire cloth and wire interweave or the embedding woven fabric emerges the earliest, and shield effectiveness is better, in 0.15MHz～20GHz scope, reach >=60dB, but fabric is thick and heavy, firmly, not folding.Metallic fiber or carbon fiber and conventional textile fabric blend fabric are to weave cotton cloth with about 5%～20% ratio and conventional textile fabric blending resultant yarn; This kind fabric is lighter, soft; Wearability is improved, but cohesive force is poor between fiber, is difficult to the spinning high grade cotton yarn; And shield effectiveness is merely 13～30dB in 0.15～3GHz scope, far inferior to wire cloth and interweave or the embedding woven fabric.Though plated metal film fabric production cost is lower, the compactness of metal film, uniformity are not as good as chemical plating and vacuum plated fabric, and feel is also poor, and fabric is hard, not folding, and production process also produces great amount of wastewater, and is seriously polluted.The chemical plating fabric has good shield effectiveness, fabrics feel soft, and good permeability, waste water is less, but chemical plating process is complicated, and the stability of plating bath is difficult to control.It is the same that plating is learned in the assimilation of vacuum metallization film fabric, good shield effectiveness is also arranged, and technology is simple, and whole technical process does not have the three wastes and produces, but vacuum coating is very thin, and the thicknesses of layers that reach shield effectiveness 60dB is very uneconomical, and cost is high.
200710039226.2 number patent application has proposed to adopt the method for vacuum sputtering coating and the compound manufacturing electromagnetic wave screen fabric of plated film, technological process is one of following two kinds: a. fabric substrate → vacuum sputtering metal-coated membrane → chemical plating metal film → wash → apply protective layer → oven dry; B. fabric substrate → catalysis → washing → activation → chemical plating metal film → washing → oven dry → vacuum sputtering metal-coated membrane → apply protective layer.Fabric is made Low Temperature Plasma Treating before the vacuum sputtering metal-coated membrane of above-mentioned two kinds of flow processs.The fabric that this method makes can reach the electromagnetic shielding effectiveness of wideband segment limit 90dB.Shortcoming be coating reach the dynamical uniformity of 90dB and reappearance not enough, and can't break through 90dB again, the fabric folding resistance is also not enough.
Existing various lining can't stop electromagnetic wave that the width of cloth of human body is penetrated.And human body is penetrated by the electromagnetic width of cloth for a long time to lead system various diseases even carcinogenic.People receive whenever and wherever possible from the nature and the artificial electromagnetic width of cloth that produces and penetrating in the society in modern times.
The fabric of traditional electromagnetic radiation shielding (being commonly called as woven wire) is weaved and is formed, and organizine that it intersects vertically each other and tram are to be made up of wire.In fabric, organizine and tram parallel distribution respectively, every organizine and every tram have only a joining.On this unique joining, be difficult to guarantee that organizine and tram fully electrically contact.On textile fabric or its fabric, be coated with (plating) transmitter; Though can play the effect of antistatic and electromagnetic radiation shielding; But laundering of textile fabrics can damage the transmitter layer, like this, make fabric reduce gradually, until the effect that loses antistatic and electromagnetic radiation shielding at last.
CN1045428A discloses a kind of fabric.This fabric is superior to the disclosed fabric of DE-A-2923286 patent, and the clothes that this fabric is made are superior to the disclosed vest of VS-A-4196355 patent.Fabric is to weave to form like this, and warp thread that it intersects vertically each other and weft yarn constitute with the scribbled of stainless steel fibre and textile fabric.Make stainless steel fibre and textile fabric blended yarn Wiring technology long flow path, will stainless steel fibre be broken to 3 to 10 centimetres short fiber earlier, then through mixed, comb, also, operations such as rove, spun yarn.In fabric, stainless steel short fiber is single or the tuftlet Discrete Distribution, distributes to be difficult to evenly.On the joining of warp thread and weft yarn, cannot say for sure that more demonstrate,proving stainless steel fibre fully electrically contacts.
The present invention relates to a kind of technology and use textile material---radiation-proof fabric and manufacturing approach thereof, said radiation-proof fabric are widely used in the protection of radiation such as carbonium that radar, electronic computer, computer, physiotherapy equipment, micro-wave oven, electronic dry machine, large-screen receiver etc. send, electromagnetic wave, x ray; The shielding material of precision instrument, cable etc.; Flat heating element; Explorer, fisherman's the life vest that plays reflex.
Along with science and technology development, society gets into electronic age, and various electronic apparatus have got into huge numbers of families again except that being widely used in industrial fields such as military project, scientific research and workers and peasants doctor, promoted the progress of human material progress at present.But simultaneously they can send electromagenetic wave radiation again, and the radiation of particles such as carbonium, a small amount of x ray, pollute the space, and the harm people's is healthy, has become great society public hazards.
For this reason, people have begun the development of radiation-proof fabric and goods thereof very early, and this radiation-proof fabric can adopt the wire weaving or common nonmetal textile material surface plating is realized metallization with metal.The wire cloth serviceability is poor, and shield effectiveness is low, the therefore main metallized method of nonmetal textile material that adopts, wherein metallising process of using more.
The technology of on natural fabric, carrying out chemical silvering was studied in 1970 in the Shanghai City Spinning Science Institute, was developed into conductive fabric, was used to make that electric power all forces to submit and the work clothes of anti-microwave.At the end of the seventies, nickel plating on synthetic fibers or the natural fabric is shunk at height by Bayer A.G, processes anti-microwave material and low pressure heating element heater.Contemporaneity has successively begun the research of fabric electroless copper plating method both at home and abroad again.Study fabric chemistry one-step method copper facing or nickel plating technology like Shanghai City Spinning Science Institute in 1980, processed copper facing or nickel plating fabric instead of chemical silver coating fabric.Nineteen eighty-three, the copper facing fabric was processed with two-step method by Textile Colloge of Shanghai Engineering and Tech. Univ..
In view of the processing of above-mentioned various plating textile materials, to the protection question industry of microwave with basic solution.But above-mentioned material mainly has been a reflex to microwave, and is then almost nil to the absorption of microwave.They are relatively poor to the effect that stops of the absorption of 30～1000MHz band limits electromagenetic wave radiation, the elimination of carbonium, a small amount of x ray, so can not play reliable and secure protective effect to human body.In order to improve the functional of radiation proof material; Increase the thickness of material effective protection aquiclude; State such as Switzerland, Japan successively adopts the material of elements such as high polymer and siliceous, carbon, lead, sodium to mix the blend fibre weaving radiation proof material that is spun into, and this material has the effect of eliminating static, absorbing high light and a small amount of x ray.
Simultaneously, though people have developed various radiation proof materials, these material majorities have single functional, like anti-microwave material, anti-x ray material etc., have certain limitation in the use.Like the plating textile material well anti-microwave property (shield effectiveness is up to 40～60 decibels) is arranged, but because the single metal of plating, coating is thinner again, so relatively poor to the barrier force of low frequency electromagnetic radiation and x ray; Increased multiple element in the synthetic fabrics protective materials though polyblend, increased the thickness of effective protection aquiclude, can eliminate fluoroscopic high light and conduction static, poor electric conductivity only can reflect and absorb 1～3 decibel low frequency and high frequency electromagnetic radiation.
Provide a kind of radiation protection ability better, especially stronger radiation-proof fabric and manufacturing approach thereof to the absorbability of radiation.
The radiation-proof fabric that proposes improves on one-step method metallization (like silver-plated, copper, nickel etc.) basis and makes; Its principal character is its woven, knitted fabric or the supatex fabric of base material for processing with the common textile fibers (chemical fibre and natural fiber) and the synthetic fibers blending of polyblending; The metal level that methods such as above-mentioned fabrics comprises that one deck is silver-plated by known chemical, copper facing or nickel plating are coated with, and by one deck with the screen printing method coating, contain multiple usable reflection and absorb seal slurry that the elemental substance of radiation forms layer.
EP 0863505 discloses a kind of wet-laying fiberglass batts that asphalt shingle is used of making, and its intensity is improved by means of the additive agent modified Lauxite binding agent of self-crosslinkable vinyl.In this felt, a spot of fiber can be can't help glass fibre and formed, and can be selected from particularly organic fiber such as nylon, polyester, polyethylene or polypropylene fibre.
FR 2434677 has instructed a kind of fibre-based veil that can be used for making asphalt membrane, and it contains severing of glass fiber and organic fiber, and particularly the PET fiber is bonded together them with a kind of binding agent, and the shrinkage factor of these fibers is less than or equal to 5% in the time of 130 ℃.But people are also in effort, through combine glass in one deck and PET fiber and further improve the tear strength properties of this type veil.
Patent WO 01/09538 and WO 01/095760 have proposed a class formation, and these structures have made up glass veil and polyester veil through the acupuncture combined techniques.According to this teaching, glass veil bonded together with a kind of binding agent before it and polyester veil are combined systematically.
WO 01/097651 has proposed a kind of similar structure, but glass veil and polyester veil combine with the fluid dynamic needle point method.
