Description
Technical field
The present invention discloses a kind of method preparing Antistatic Fabric, belongs to field of textile.
Background technology
The harm of electrostatic is a lot, and its first harm derives from the interaction of electrical body.Aircraft electrification can be made when the particulates such as airframe and air, aqueous vapor, dust rub, if do not taken measures, will the normal work of severe jamming aircraft radio set, make aircraft become deaf person and blind person; In printing house, the electrostatic between page can make page be bonded together, and is difficult to separately, make troubles to printing; In pharmaceutical factory.Due to electrostatic attraction dust, the substandard purity of medicine can be made; The easy attract dust of the electrostatic of screen surface and greasy dirt when placing TV, form the film of one deck dust, and the readability of image and brightness are reduced; Just common on blending clothes and the dust not easily clapped, is also the ghost that electrostatic is smash.The second largest harm of electrostatic is likely blasted because electrostatic spark lights some flammable object.Black night evening, when we take off nylon, wool clothes, can send the sound of spark and " ", this is substantially harmless to human body.But on operating table, except electric spark can cause narcotic blast, injury doctor and patient; In colliery, then can cause gas explosion, workman's casualties can be caused, mine abandonment.In a word, electrostatic hazard results from electric power and electrostatic spark, and static discharge the most serious in electrostatic hazard causes the on fire of combustible and blast.It has often been said, prevent trouble before it happens, prevent that the measure of electrostatic is all generally reduce flow velocity and flow, the process procedure that transformation electrification is strong, adopt the equipment and materials etc. that electrification is less.The simplest the most reliable way is again with wire equipment ground, electric charge can be induced one greatly, to avoid accumulation of static electricity like this.Careful passenger probably can find; All discharge brush is housed at the both sides wing tip of aircraft and the afterbody of aircraft, during aircraft landing, in order to be electrically shocked when flying under preventing passenger, undercarriage mostly use special ground connection tire or earth connection; With the electrostatic charge that aircraft of releasing is produced aloft.We also often see that the afterbody of oil truck drags an iron chains, the earth connection of Here it is car.The humidity of suitable increase working environment, allows electric charge release at any time, also effectively can eliminate electrostatic.In wet weather, the test of want some doing electrostatic, is exactly this reason.The antistatic additive of scientific research personnel's research, then can eliminate the electrostatic of insulator inside well.
Summary of the invention
The invention provides a kind of preparation method of Antistatic Fabric, it is realized by following technical scheme:
In textile printing and dyeing processing, adopt infusion process or padding method to be applied to the surface of weaving face fabric antistatic material, then dry obtained Antistatic Fabric.
Particularly, with terylene, polyamide fibre or spandex for raw material manufacture all kinds of fabric time, reprocess shaping after adding the first mechanical mixture of antistatic additive.Various antistatic additive molecule produces except giving the certain lubricity of polymer surface, reduction coefficient of friction, suppression and minimizing electrostatic charge.
Clothes of the present invention adopts synthetic fiber, and it is specially: terylene, polyamide fibre, spandex, polypropylene fibre (polypropylene fibre), polyacrylonitrile fibre (acrylic fibers) or vinylon (vinylon).
Antistatic additive is different according to occupation mode, and antistatic additive can be divided into outer spreading type and two kinds, interior mixed type.
The present invention also applies one deck antistatic additive with outer spreading type antistatic additive on the surface of fabric, and concrete technology is the modes such as spraying, dipping or coating.
Particularly, antistatic additive is first deployed into water or ethanol etc. the solution that mass fraction is 0.2% ~ 2.0%; Then make it to be attached to synthetic fiber surface by coating, spraying or impregnating method, then form antistatic coating through room temperature or heated air drying.
Particularly, above-mentionedly electrostatic agent is added water or alcohol solvent is deployed into the solution that mass fraction is 1.0%.
Antistatic additive is because the volume resistance of polymer is generally up to 10
10~ 10
20Ω/cm
2.Antistatic additive generally all has the feature of surfactant, and in structure, polar group and non-polar group have both at the same time.Conventional polar group (i.e. hydrophilic group) has: the anion of carboxylic acid, sulfonic acid, sulfuric acid, phosphoric acid, the CATION of amine salt, quaternary ammonium salt, and the group such as-OH ,-O-, and conventional non-polar group (i.e. lipophilic group or hydrophobic group) has: alkyl, alkaryl etc.
Antistatic additive of the present invention is anionic antistatic agents, and it is the alkali metal salt of alkyl sulfonic acid, phosphoric acid or aminodithioformic acid, as sodium alkyl sulfonate.
The mechanism of action of outer spreading type antistatic additive of the present invention is added in solvent by this kind of antistatic additive, and the hydrophilic group in antistatic additive molecule just inserts in solution, and lipophilic group just stretches to air.When with this solution impregnation macromolecular material, the lipophilic group in antistatic additive molecule will be adsorbed in material surface.Flood rear drying, deviate from the polymer surface after moisture, hydrophilic group in antistatic additive molecule all arranges towards air side, easy absorbing environmental moisture or combined with the moisture in air by hydrogen bond, form a unimolecule conductive layer, the electrostatic charge of generation is leaked rapidly and reaches anti-static purpose.
Particularly, the compatibility of antistatic additive and polymer follows the close compatibility principle of polarity.Macromolecular material all has Long carbon chain structure, belongs to non-polar resin more, and what have has terminal polar group, enhances polarity.Antistatic additive has hydrophobic group (nonpolar) and hydrophilic group (polarity) simultaneously.General hydrophobic group carbochain is longer, better with the compatibility of polymer.If hydrophilic group polarity is very strong, then bad with the compatibility of polymer; If polarity is more weak, then hydrophilic adsorption is poor.Compatibility is very good, and antistatic additive is not easily moved out, and does not reach antistatic effect; Compatibility is bad, and move out too fast, the lasting period is too short, affects Long-Time Service.Therefore need to consider above-mentioned factor when design and use antistatic additive, screen kind and the optimum quantum of utilization of antistatic additive by experiment.
Wherein antistatic additive is added after solvent dissolves, make the concentration of solution under the prerequisite ensureing antistatic effect, dilute as far as possible, because the solution of high concentration can be clamminess, like this can than being easier to attract dust.
Conventional coating process infusion process, direct method or spraying process.
Direct method is coated on goods by antistatic additive liquid with instruments such as cotton, flannel, hairbrush and rollers.It is simple and effective, uses the widest.Infusion process is immersed by goods in antistatic additive liquid, and it is applicable to complex-shaped or large numbers of small articles.Spraying process is sprayed on goods with spray gun by antistatic additive liquid, and it has speed fast, the advantages such as efficiency is high, and film is even.
Particularly, the solution of the present invention's to be the solvent of the solution be configured to by above-mentioned antistatic additive be water or water and ethanol.
Above-mentioned antistatic additive is one or more mixing in polyoxyethylene alkylphenol ether sulfuric ester, alkyl phosphate, alkyl phosphate diethanolamine salt, dodecyl, polyamine class, polyester polyethers, polyacrylate.
Anion surfactant, as polyoxyethylene alkylphenol ether sulfuric ester, alkyl phosphate etc. can on fiber oriented attachment, lipophilic group is towards fiber, the hydrophilic radical of anion is towards air, and associate with water, improve fiber surface conductance, reveal electric charge rapidly, reach anlistatig effect.
Durable antistatic agent has polyamine class, polyester polyethers (block copolymer of terephthalic acid (TPA), ethylene glycol, polyethylene glycol, its basic structure is similar with terylene) has excellent durable antistatic and soft effect.Polyacrylate (acrylic acid (or methacrylic acid) and acrylate) can form anionic hydrophilic film at fiber surface with the copolymer of hydrophilic monomer.Owing to having the carboxyl that hydrophily is very strong in polyacrylic acid ester molecule, so antistatic effect is pretty good, washability is fine, is also well suited for terylene.
By the raw material furnishing mixed solution of above-mentioned weight portion, be sprayed on fabric; Then heat treatment: heat treatment 2 ~ 20min under the condition of temperature 80 ~ 120 DEG C, makes conductive materials be attached to the surface of fiber; Then drying, shape, is the 30 ~ 50s that shapes under the condition of 120 ~ 140 DEG C in temperature after drying and processing.
Immersion during weaving face fabric antistatic additive arranges or pad antistatic additive, the step such as dry or cure.
Technological merit of the present invention: the antistatic mode by outer painting of the present invention is added to the surface of fabric panel, has superior electrostatic-proof function; Can with anion or nonionic textile finishing auxiliary agent used in combination; The content of antistatic additive adds few, to the non-stimulated allergic reaction of skin in component concentration ranges, without potential carcinogenic; Anlistatig good endurance, washability is good; Not containing harmful substances such as formaldehyde, heavy metal ion and aromatic amine compounds, meet environmental requirement; Use artificial fibre and the natural fabrics such as real silk, animal skin such as various terylene, polyamide fibre, polyvinyl chloride fibre, little on other physical properties such as feel, color and luster impact of fabric.
