Description
Technical field
The present invention relates to electromangnetic spectrum field, particularly relate to a kind of electromagnetic shielding knitted fabric and purposes with the weft knitting of carbon filament cladded yarn.
Background technology
Increasingly extensive along with electrical equipment application, electromagnetic radiation has become a kind of new pollution.Human body long term exposure is in electromagnetic radiation environment, and nervous system, cardiovascular system, internal system, reproductive system etc. all can be subject to injury in various degree.For protect human body not to be subject to or to reduce the harm of electromagnetic radiation as far as possible, people shield electromagnetic radiation source on the one hand, reduce amount of radiation, develop on the other hand effective protective materials and carry out individual protection, and electromagnetic radiation fabric is one of them.The fabric that exploitation at present has electromagnetic wave shielding function mainly contains two kinds of approach, and the one, on fabric, apply the top finish with electromagnetic wave shielding performance, the 2nd, use the fiber process with electro-magnetic screen function to become fabric.
About the first approach, existing a lot of patent reports, Chinese patent CN200910054882.9 utilizes the method for chemical silvering to form one deck silver on dacron surface, thereby gives fabric electromagnetic wave shielding.Chinese patent CN200910048743.5 utilizes the method for electroless copper to form layer of copper on dacron surface, thereby gives fabric electromagnetic wave shielding.The method that Chinese patent CN200610119515.9 utilizes vacuum sputtering is one or more in metallic aluminium, silver, iron, nickel, chromium, gold, platinum or magnesium; Or for one or more in the oxide of metallic aluminium, silver, iron, nickel, chromium, gold, platinum or magnesium form film on fabric, give fabric electromagnetic shielding action.Metal coating is wash resistant not, and after washing repeatedly, effectiveness declines serious, and plated film fabric feeling is thick and stiff, and gas permeability is bad, and complex process, in order to reach often coating repeatedly of good shield effectiveness.These are completely different from the woven mode of composite yarn that the present invention adopts.
About the second approach, be generally to spin or and the common then woven into fabric of fiber blend of taking so that metal fibre is pure.Chinese patent CN101423996A utilizes permalloy and takes yarns interwoven and make fabric and realize electromagnetic shielding.The blended yarn of cotton fiber and stainless steel fibre is made into Electromagnetically shielding fabrics by Chinese patent CN1045428A.Chinese patent CN87103582A utilizes nickel fiber and can spin fire resistance fibre blended yarn to be made into Electromagnetically shielding fabrics.The ratio of metal fibre is great, and the fabric being made into is thick and heavy, and wiriness, and skin is had to spread effect.The common fiber of taking is carried out the coat of metal and makes conductive fiber and be also attributed to second method, and Chinese patent CN201395671Y is silver-plated to chemical-fibres filaments, then interweaves with common yarn, obtains high shielding radiation-prevention fabric.
The textiles made from carbon fiber can be used as electromagnetic shielding material, because the electrical property of carbon fiber is similar to metal.The resistivity of carbon fiber is (1. 5 ~ 3. 0) × 10
-3Ω cm, be a kind of outstanding electromagnetic armouring structure material, but carbon fiber is very crisp, is easy to occur the situation of filament fracture in BENDING PROCESS.Therefore, the application of most of carbon fibre composite is first all the structural material that preformed and then the solidifying and setting of resinizing are made into required form.And current processing method is mainly to utilize special 3 D weaving equipment that carbon filament yarn is woven into three dimensional fabric and then the cooling composite that obtains of coated with resins sizing.In the process of braiding, carbon filament yarn easy fracture and surface easily sanding form filoplume, so carbon fiber is difficult to form fabric.Someone once attempted soaking into the collecting agent such as paste, finish on carbon filament and improved cluster performance, but used collecting agent in order to improve cluster performance, can make carbon filament become thick and stiff.At patent documentation: Unexamined Patent 2-133632 communique is upper makes durability sewing thread and yarn with thermoplasticity multifilament looping carbon fiber, at patent documentation: having spun carbon fiber with the spinning system of hollow ingot on JP 64-061527 communique is the wrap yarn that heart yarn is coated by superhigh molecular weight polyethylene fibers, retain that carbon filament is high-strength, the advantage of Gao Mo, and suppressed the generation of carbon fiber filoplume.This is how to protect carbon fibre tow injury-free in expression.
U.S. Pat P provides a kind of method of preparing carbon fibre fabric for No. 4237108, will be woven into cloth through the Dralon of HEAT SETTING processing, then carries out oxidation processes, and then carbonization treatment, obtains carbon fibre fabric.Chinese patent CN 200780014529.7 provides a kind of method of utilizing air-jet loom weaving carbon cloth, take the carbon fiber sliver of fiber number 400-6000tex as warp thread, 1/5 or following auxiliary fiber take fiber number as this carbon fiber sliver are weft weaving one-way carbon fibre fabric, have overcome well carbon fiber fluffing problem in weaving process.But the method can only woven carbon fibre one-way fabric, and weaves parameter adjustment more complicated, also there is certain limitation to weave to prevent carbon fiber fluffing impact through close, filling density.These are in the processing problems that solves pure carbon fiber fabric, and the principle knitting from the composite yarn of the present invention's employing is completely different.
Appeal electromagnetic wave screen fabric or title Electromagnetically shielding fabrics are all woven fabrics, are all to carry out electromagnetic wave shielding in the mode of homogeneous body, have the fundamental difference in principle, method, structure and purposes with the present invention.
Knitted structure is because its structure is mutually to go here and there and overlap between coil, and this characteristic has determined that knitted fabric is than woven fabric softness, also has the patent of this respect to adopt knitting method to prepare radiation-proof fabric.U.S. Pat P 5968854 carries out the silver-plated electrically conductive filament yarn of making to chemical-fibres filaments such as nylon, then adopts knitted structure to be made into the anti-radiation knitted thing of high conduction.Can overcome the shortcoming of the thick and heavy and chafe of metal fibre to the direct plating of chemical-fibres filaments, also can overcome that metal-coated membrane fabric feeling is thick and stiff, gas permeability is bad and not wash fast shortcoming, but have equally the problem of complex process.Chinese patent CN200910181902.9 provides a kind of preparation method of warm-keeping anti-radiation knitted fabric, adopting radiation resistant fiber yarn (being mainly metal blend fibre composition) and elastomeric yarn to go the same way to weave forms, as front, the inside forms for face fibre weaves, between the inside and front, be connected with connection yarn braiding, a kind of warm-keeping anti-radiation resilient knit fabric again that can napping, zoarium comfortable and easy to wear.But this patent is not pointed out according to the radiation-resistant shielding property that need to regulate by tissue design fabric of reality.The carbon fiber composite yarn weft knitting that this and the present invention adopt, adopts the mode of different tissues structure and the arranging density of control fabric completely different.
The most close is that Chinese patent CN200710190584.3 provides a kind of method of preparing carbon fibre fabric, become barrier fabric by regenerated celulose fibre or polyacrylonitrile fibre yarn weaving, obtain graphite fibre yarn net as base cloth take high-temperature heating, utilize dry method jet spinning and form fabric.Although weave then carbonization and form the method for carbon fibre fabric and avoided the problem of carbon fiber fluffing with Dralon or regenerated celulose fibre, fiber is by heat treatment meeting generation thermal contraction, in the time that being heat-treated, the inadequate fabric of carbonization can make because of thermal contraction fibre deformation, affect outward appearance and the flatness of fabric, and high-temperature process certainly will want lot of energy, energy-conservation not.But the method is also to use machine-knitted structure, first make lattice-shaped fabric with regenerated celulose fibre or polyacrylonitrile fibre, then carbonization obtains revealing the fabric of empty lattice-shaped pure carbon fiber, its objective is the damage to carbon fiber in weaving for fear of spinning, and can not serve as DRESS FABRIC, these are all different from principle of the present invention, forming mode and form of fabric.
The present invention uses carbon filament cladded yarn, has directly avoided the weakness of carbon filament yarn easy damage grain raising in braiding process.Carbon filament can, as common yarn, be weaved on common weft machine, both provide for the underwear of electromagnetic wave shielding and protection and the electromagnetic shielding knitted fabric of other textiless, widened again the scope of application of carbon filament bundle fiber.
