Description

A kind of anion polyester fiber capable of being dyed at normal and its production and application
Technical field
The invention belongs to polyester fiber and preparation thereof and Application Areas, particularly relate to a kind of anion polyester fiber capable of being dyed at normal and its production and application.
Background technology
Terylene (PET) fiber, function admirable, of many uses low because of its cost is subjected to people day by day and payes attention to.The American produces terylene since nineteen fifty-three, and 2006, global terylene output surpassed 27000kt, accounts for 67% of synthetic fiber total output.Terylene has become utilization fiber the most widely.People had proposed many method of modifying to the PET fiber and make Woven fabric and clothes have more wearing comfortableness and wholesomeness in recent years.But the PET fiber can not be realized multiple functional coexistence for a long time, has limited the variation of fabric variety.In recent years, about the research of the raising of PET fiber stylization and anionic property has had breakthrough progress respectively, but how these two functions are organically combined, realize fiber coloredization and the unification that high effect negative ion takes place, caused the concern of Chinese scholars.
Ferroelectric material is a class important functional material.Its most basic characteristic is for can have spontaneous polarization in some temperature range, and polarization intensity can be reverse and reverse with external electric field, thereby ferroelectric hysteresis loop occurs.Find now that it is a lot of to have a ferroelectric crystal, gets up can be divided into two big classes but summarize:
A. a class is with potassium dihydrogen phosphate KH 2PO 4Abbreviation KDP is representative, has hydrogen bond, and they carry out the transition to ferroelectric from paraelectric phase similarly is the phase transformation of disorder to order.With KDP is the hydrogen bond sections transistor of representative, and the data of neutron diffraction show that more than Curie temperature, proton is to become the shape of symmetry along exhibition along the distribution of hydrogen bond.When being lower than Curie temperature, contiguous ion is concentrated and is asymmetric with in the distribution of proton, and proton can be than the end near hydrogen bond.
B. another kind of then is representative with the barium titanate, and the transition from paraelectric phase to ferroelectric picture is because wherein two sublattice generation relative displacements.For the Ca-Ti ore type ferroelectric of thinking representative, diffraction experiment showed, that the appearance of spontaneous polarization is because the sublattice of cation and the sublattice generation relative displacement of anion.Wherein, BaTiO 3Series ferroelectric especially barium strontium titanate (BST) has caused that people pay close attention to and enough attention widely, this be because it have high-k, strong dielectric, nonlinear, indefatigability, advantage such as Curie temperature is adjustable.But it has fatal weakness: when applying direct current electric field surpasses hundreds of 10 3After the V/cm, its leakage current density rising several magnitude, and 2 * 10 6Puncture about V/cm.Compare barium zirconium phthalate BaZr with BST xTi 1-xO 3, BZT) compressive resistance is higher, and this is because Zr 4+Compare Ti 4+Ionic radius big (being respectively 0.087nm and 0.068nm), can increase the lattice paprmeter of material and Zr 4+Compare Ti 4+Chemical stability good.Therefore, people consider to replace BST with BZT.And such material also can produce piezo-electric effect, because preparation technology is simple, cost is low, and has mechanical property and stable piezoelectric property preferably, and purposes is general on current market.
Piezoelectric ceramics, a kind of can be with mechanical energy and the electric energy ceramic material of conversion mutually.Is piezoelectric ceramics a kind of which type of material on earth? piezoelectric ceramics belongs to Inorganic Non-metallic Materials.This is a kind of material with piezo-electric effect.So-called piezo-electric effect is meant some medium under the effect of power, produces deformation, causes that dielectric surface is charged, and this is a direct piezoelectric effect.Otherwise, applying excitation electrical field, medium will produce mechanically deform, claim inverse piezoelectric effect.This marvellous effect is applied in the closely-related many fields of living with people by scientist, to realize functions such as power conversion, sensing, driving, FREQUENCY CONTROL.
Aspect power conversion, utilize piezoelectric ceramics to convert mechanical energy the characteristic of electric energy to, can produce piezoelectrics, mobile X-ray power supply, shell apparatus to cause bursting.The flint that just has piezoelectric ceramics to make in the electronic lighter, the sparking number of times can be more than 1,000,000 times.With piezoelectric ceramics electric energy is converted to ultrasonic vibration, can be used for seeking position and the shape of the shoal of fish under water, metal is carried out nondestructive inspection, and ultrasonic cleaning, ultrasonic medical, can also make various ultrasonic slitters, welder and flatiron, plastics even metal are processed.But, in the main component in the now used piezoceramic material, PbO (or Pb 3O 4) content account for 70% of raw material total amount, PbTiO 3, Pb (Ti 1-xZr x) O 3Also belong to such material.
The performance of ceramic material depends on its composition and microstructure, and " microstructure is in the architectural feature of ceramic middle finger polycrystalline or heterogeneous material, and its research comprises aspects such as the quantity of orientation, phase of crystallite dimension, grain shape and distribution, particle and the porosity.
Because pet fiber originally can only be used DISPERSE DYES, azo dye dyeing, so exist the problem that is difficult to obtain bright-coloured and dense form and aspect.People have proposed various material in polyester resin as the method that addresses this problem.For example, in Japanese Patent Publication 34-10497 communique, a kind of M-phthalic acid composition that contains the metal organic sulfonate base that makes 2～3 moles of % and polyethylene terephthalate copolymer have been proposed and dyeable polyester.And in Japanese kokai publication sho 63-256716 communique, following such technical scheme has been proposed: if when being polyethylene glycol copolymerization more than 200 with molecular weight, owing to have easily dying effect, and can make polyethylene glycol show plasticization effect, can reduce the thickening power that causes by sulfonate group, so can improve the degree of polymerization of polymer.In addition, someone has also proposed following such technical scheme at Japanese kokai publication sho 62-89725 communique: with straight chain hydrocarbon system dicarboxylic acids such as adipic acid, decanedioic acid or diethylene glycol (DEG), neopentyl glycol, cyclohexanedimethanol, 1, dihydroxylic alcohols such as 4-two (beta-hydroxy ethyoxyl) benzene show the resin material of normal pressure stainability with containing the copolymer that sulfonic M-phthalic acid copolymerization obtains.Controlling fiber under certain pressure promptly under near the temperature 80～100 ℃, thereby can dye fully can reduce the energy simultaneously can be when the processing of road, back the control fiber surface influence Color with inner anion powder nondiscolouring, emissivity that also must the assurance anion simultaneously.

Tourmaline is that a kind of borosilicic acid salt mineral can be divided into dravite, the iron tourmaline of black, roseate elbaite, nattier blue tsilaisite and the bottle-green chromium tourmaline that is brown and yellow according to the end of the R in crystal structure component difference.The crystal structure of tourmaline is a trigonal system, it is the multiple tripartite ring that silicon-oxy tetrahedron is formed, because crystal structure is special, cause the atom of two high electric charges on the crystallization screen work, to arrange obviously dislocation, causing crystal one end thus is the electric charge positive pole, the other end is the electric charge negative pole, and flowing to from negative pole that electronics is eternal is anodal, thereby has formed electric current and electrostatic field.
(1) static for good and all produces weak current, forming electrostatic field tourmaline crystal structure itself has permanent charged and forever keeping the characteristic of positive pole and negative pole, it and uranium ore have radioactivity and form radiation field, and it is the same that magnetic iron ore has magnetic formation magnetic field, has the characteristic that forms electric field.Test after deliberation, tourmaline capable forever constantly sends the electric current of 0.16 μ A, and its reason is that the positive pole of tourmaline absorbs the anion in the atmosphere, and it is stored in its crystals, and unnecessary anion can be emitted from negative pole, thereby has formed the characteristic of permanent discharge.Tourmaline flash-over characteristic after heating and pressurizing can be further strengthened, 10 ℃ of effect multiplications of the every raising of temperature.Tourmaline is through pulverizing, and its discharge performance is constant, and must be many more with thin more its generation of static electricity of tourmaline of amount, and voltage is also high more.
(2) produce anion, can reduce the alkalescence of water simultaneously again in a flash the water negative ionization after instant water negative ionization tourmaline is touched water.Its principle is that the electronics of tourmaline negative electrode sparks once touching water, and brine electrolysis becomes hydrogen ion and hydroxide ion, and hydrogen ion combines and is neutralized with the anion that tourmaline sends, and has become general hydrogen atom and has discharged.Hydroxide ion then combines with hydrone, constantly produces hydroxyl anion or alkaline anion (H that a kind of surface has active function 3O 2 -).The water of this process of process is owing to hydrionic minimizing has had low alkalinity.Same tourmaline touches airborne moisture content, and the sweat of human body and hydrone also react and produce anion and enter human body then.
(3) the effect hydrone of activated water is assembled a lot of words and has just been formed a water, has manyly just formed one glass of water, and it is the group of molecules of several water molecules bodies, owing to contain chlorine and impurity in the running water, tens water molecules often, this water was both bad to be drunk, and is difficult for again being absorbed by the body.Tourmaline is put into water, because its voltage effect, the hydrone component is separated and is diminished, and becomes the water of not only drinking but also be beneficial to health well, and Here it is tourmaline is to the activation of water, and the water that is activated is to the impregnability of skin and cell, and absorbent properties improve.
(4) emitting far-infrared tourmaline has the characteristic of the far infrared of radiation 4～18 mum wavelengths.Human body is frequent release heat, and tourmaline can absorb this heat energy and convert anion to and far infrared reacts on human body.Far infrared can warm cell, improves blood circulation, enhances metabolism, and strengthens the vigor of cell, just the thermogenetic effect of often saying.Utilize this characteristic of tourmaline, some disease of human body is treated, improve looks and the various effects that improve the mood aspect are proved widely, as set up, strengthen gastrointestinal function, relax pain, alleviate chill physique etc.
(5) the permanent chargeding performance of the surface-activity effect tourmaline of tourmaline can brine electrolysis, generates hydroxidion (H 3O 2 -), hydroxidion has surface-activity effect (make the emulsification of human body oil content, soak into, disperse, dissolve), reduction (in and acidic materials), cleaning action (go bacterium, antibiotic, sterilization), deodorizing etc.
But these technology are gathered to be applied to then has certain degree of difficulty because for functional fibre processing technology not of the same race and material harsh requirement is arranged in the fiber production, is difficult to that it is unified to produce multiple function simultaneously and the polyster fibre deposited may cause degradation problem under normally moulding, fiber quality decline, the qualification rate.
But therefore crude tourmaline is difficult to adjustment Masterbatch proportioning owing to have various color and lusters when the preparation colored fibre, cause puzzlement for dyeing.Therefore the tourmaline for preparing colourless or light produced anion being necessary very.
Beneficial effect
(1) the stretched or twisting of normal-temperature normal-pressure dyeable anion long filament of the present invention, the fiber softening high resilience, style is close with wool fabric, and odd-shaped cross section can give fiber special style;
(2) the anion powder function admirable used of the present invention, addition is few, reunite less, anion emission rate height, can prepare high-load ratio master batch, good with the macromolecular material compatibility, do not influence the original performance and the production requirement of material substantially;
(3) production technology of the present invention realizes easily, effectively reduces the printing and dyeing cost simultaneously, is suitable for suitability for industrialized production.
