A kind of preparation method of Novel radiation-protection fabricTechnical field:
The invention belongs to functions of textile fabrics design ap-plication field, relate to a kind of preparation method of Novel radiation-protection fabric.
Background technology:
Electromagnetic wave be known as after water source, air and noise there is larger harm and the pollution sources not easily protected, this high-tech pollution not only affects communication, even directly threatens the health of the mankind.
At present, anti-radiation face fabric mainly contains: (1) metal fibre and blended union fabric thereof: divide again wire and take the blended fabric of yarn and metal fibre and take the BLENDED FABRIC of fiber.Wire and the blended fabric taking yarn are the electromagnetic wave screen fabrics used the earliest.In the ordinary course of things, the mixed proportion of metal fibre, can lower than 15% or higher than 30% when having a particular/special requirement between 15% ~ 30%.(2) the radiation resistant fiber fabric made of co-blended spinning method: by have the inorganic particulate of electro-magnetic screen function or powder and common fibre-forming polymer cut into slices blended after carry out spinning, the fiber with satisfactory electrical conductivity can be prepared, make again fiber not lose original intensity, extensibility, washability and ABRASION RESISTANCE.(3) vacuum-coating metal fabric: be generally made up of the primary coat of base cloth, vacuum aluminum-coated and table painting.(4) metal-coated fabric: adopt very ripe coating technology, electroconductive magnetic material is penetrated in coating slurry, the fabric of improvement is obtained shielding electromagnetic waves ability, and the main feature of metal-coated fabric is that shield effectiveness is general, airtight, feel is poor.(5) graft copolymerization loomage: the mainly sulfide of the metal such as silver, copper, tin and iodide.(6) chemical plating metal fabric: divide again chemical silver coating fabric, electroless copper fabric, by formaldehyde or reducing sugar and silver-colored ammion complex salt generation redox reaction, deposits one deck silver at fabric face.The main feature of chemical silvering fabric is that shield effectiveness is very good, and quality is soft, air-permeable anti-bacterial, corrosion-resistant, but silver is expensive, because which limit the possibility of extensive use.(7) Composite Coatings fabric: copper nickel composite plating method prepares metallized fabrics, both can ensure the capability of electromagnetic shielding of fabric, can improve again the performance of fabric antioxidant anticorrosive.
Summary of the invention:
Technical problem solved by the invention: the various problem and shortage existed for radiation-proof fabric in prior art, the invention provides a kind of radiation-proof fabric, it has good flexibility and gas permeability, there is good snugness of fit, simultaneously for long wave, in involve shortwave electric-field intensity all there is good shielding property, market popularization value is high.
For overcoming the above problems, the invention provides following technical scheme:
A preparation method for Novel radiation-protection fabric, comprises half combing spinning process and postfinishing process;

Bluish dogbane, former title " wild flax ", " camellia fiber crops ", have another name called wartwort fiber crops, bluish dogbane, sage, English name Apocynumvenetum, belong to the upright fruticuli of the perennial fallen leaves of Apocynaceae.Apocynum fibre is as a kind of new function textile material, its aboundresources, reproducibility, biodegradability, nonstaining property in process, distinctive antibiotic property, antiultraviolet, the functional characteristic such as far infrared and high wet absorption and discharging, bluish dogbane fabric has the worn-out ultraviolet ability of well screen, Shanghai Inst. of Technical Physics, Chinese Academy of Sciences has carried out testing research to the bluish dogbane of modish company and cotton blended knitted fabric, result shows that bluish dogbane underwear has stronger uvioresistant good fortune and penetrates the characteristic penetrated, ultraviolet is had jurisdiction over the penetrance of penetrating and is only 2%, health can be protected preferably from ultraviolet infringement.Bluish dogbane also has launches far function this far-infrared engergy and produces biological effect to human body, and improve microcirculation in human body, activation histocyte, improves metabolism, strengthens immunocompetence, reaches to keep fit the effect that gets rid of illness.In addition, far infrared makes bluish dogbane fabric have thermal effect, and its warmth retention property is 2 times of cotton underwear below 8 DEG C, and more than 21 DEG C gas permeabilities are 2.5 times of pure cotton fabric, the characteristic of unique " winter warms up the summer and feels well ".
Cellulose and aceticanhydride react and obtain cellulose acetate, form cellulose acetate fibers through spinning, are called for short acetate fibre.Acetate fibre is a large kind of artificial fibre, comprises two type acetate fibres and triacetate two class.Acetate fibre absorbability comfortableness comparatively cellulose fibre pin surpasses, and triacetate easily produces electrostatic, and the strength ratio viscose of diacetate fibre is poor, wet strong also low, but the wet strong amplitude declined is large less than viscose acetal fibre, and ABRASION RESISTANCE is poor.Diacetate fibre is long filament, occurs greatly, be usually used in lining, necktie, tippet etc. mainly with silk style.Triacetate is long is staple fibre, with cotton synthetic fibre blending, for the system of knitting through compiling fleece fabric, blouse and skirt.Triacetate has good elasticity and recovery, and elasticity is greater than and disposes fiber.
Silver plated metals fiber preparation process take polyamide fibre as core, adopts the manufacturing technique of physical vapour deposition (PVD) (PVD) silver plated fiber and silver-plated film, be divided into pre-treatment process and composite film coating technique.Pre-treatment is non-conductive based on organic fiber, then first use physical vapour deposition (PVD) silver ion, and then add thickness coating with composite plating method, and the silver coating average thickness of silver plated metals fiber is 0.32-0.38 μm, and resistivity is 5.26828 × 10-6Ω m.
Beneficial effect of the present invention:
1. the inventive method prepare to radiation-proof fabric there is good flexibility and gas permeability, there is good snugness of fit.
2. the radiation-proof fabric for preparing of the present invention for long wave, in involve shortwave electric-field intensity all there is good shielding property, market popularization value is high.
3. fabric of the present invention is also provided with good antistatic and anti-microbial property.
