Description
Technical field
The present invention relates to the electromangnetic spectrum field, particularly relate to a kind of electromagnetic shielding braided fabric and purposes of carbon filament cladded yarn.
Background technology
Along with electrical equipment and communication tool use increasingly extensive, electromagnetic radiation has become a kind of new pollution.The 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 the protection human body is not subjected to or reduces electromagnetic radiation hazards as far as possible, people shield electromagnetic radiation source on the one hand, to reduce amount of radiation.On the other hand, develop effective protective materials and carry out individual protection, electromagnetic radiation fabric is namely one of them.The fabric with electromagnetic wave shielding function of exploitation is mainly dual mode at present: the one, apply the top finish with electromagnetic wave shielding performance material on fabric; The 2nd, become fabric with the fiber process with electro-magnetic screen function.
About first kind of way, existing a lot of patent reports, Chinese patent CN200910054882.9 utilize the method for chemical silvering to give the fabric electromagnetic wave shielding at dacron surface formation one deck silver.The method that Chinese patent CN200910048743.5 utilizes electroless copper forms layer of copper and gives the fabric electromagnetic wave shielding on the dacron surface.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 the fabric electromagnetic shielding action.Metal coating not wash resistant, fabric feeling is thick and stiff, gas permeability is poor and complex process, is its defective.These are fully different from the woven mode of carbon filament cladded yarn that the present invention adopts.
About the second way, 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.Chinese patent CN1045428A is that the blended yarn with cotton fiber and stainless steel fibre is made into Electromagnetically shielding fabrics.Chinese patent CN87103582A utilizes the nickel fiber and can spin the fire resistance fibre blended yarn to be made into Electromagnetically shielding fabrics.The ratio of metal fibre is great, and the fabric that is made into is thick and heavy, and wiriness has spread effect to skin.The common fiber of taking is carried out the coat of metal and makes conductive fiber and also be attributed to the second way, and Chinese patent CN201395671Y is silver-plated to chemical-fibres filaments, then interweaves with common yarn, obtains high shielding radiation-prevention fabric.5968854 pairs of chemical-fibres filaments such as nylon of US Patent No. P carry out the silver-plated electrically conductive filament yarn of making, and then adopt 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, can overcome also that the metal-coated membrane fabric feeling is thick and stiff, gas permeability is bad and not wash fast shortcoming, but the problem of complex process is arranged equally.This weaves, adopts the principle of electromagnetic shield-ing of different structure and arrangement fully different from the carbon filament cladded yarn that the present invention adopts.
The textiles made from carbon filament 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 at first all the structural material that preformed and then the solidifying and setting of resinizing are made into required form.And present processing method is mainly to utilize special-purpose 3 D weaving equipment that the carbon filament yarn is woven into three dimensional fabric and then the cooling composite that obtains of coated with resins typing.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 agents such as paste, finish and improved cluster performance on carbon filament, 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 the 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, kept 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.
US Patent No. P provides a kind of method for preparing carbon fibre fabric for No. 4237108, will be woven into cloth through the Dralon that HEAT SETTING is processed, then carry out oxidation processes, and then carbonization treatment, obtain carbon fibre fabric.Chinese patent CN 200780014529.7 provides a kind of method of utilizing the 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 the woven carbon fibre one-way fabric, and weaves the parameter adjustment more complicated, also has certain limitation to weave to prevent carbon fiber fluffing impact through close, filling density.These are in the processing problems that solves the pure carbon fiber fabric, and the principle of the carbon filament cladded yarn weave woven that adopts from the present invention is fully different.
Above-mentioned electromagnetic wave screen fabric or claim that Electromagnetically shielding fabrics is all the mode with homogeneous body improves the electromagnetic wave shielding of fabric by increasing fiber content, all different from the present invention on principle, method, structure and purposes.
The most close is that Chinese patent CN200710190584.3 provides a kind of method for preparing carbon fibre fabric, yarn with viscose glue or polyacrylonitrile fibre first is woven into the barrier fabric, obtain the base cloth of graphitization yarn grid with high-temperature heating, then form fabric with the dry method jet spinning on this base cloth.Obviously, this processing time consuming consumes energy, the whole fragility of base cloth is large, and the gained fabric is without flexibility.To adopt the carbon filament cladded yarn directly to be woven into principle, forming mode and the form of fabric of flexible fabric all different from the present invention.
