10Ohm-centimetre, constant through 20 standard washings, be applicable to desirable supplementary material in industry manufacturings such as making dust-free clothes, aseptic clothing, anti-blast clothing etc., particularly precision instrument, integrated circuit, computer and the application process.
Description
The invention relates to antistatic additive and be added on fibrous inside to make the technology of durable anti-static polyester resin and fiber.
As everyone knows, terylene is hydrophobic organic high molecular compound, and it can not ionization, does not have free electron again, and therefore the very easy electric charge that gathers causes all consequences, has a strong impact on use value.At present, the method for eliminating terylene static mainly contains two kinds, and the one, surface treatment is promptly at the surperficial coated antistatic additive of fiber and fabric thereof; The 2nd, basic modification, promptly add antistatic additive at fibrous inside to give its antistatic property.Obviously, the former is because in processing, dyeing and finishing, washing and use, the fiber surface antistatic additive loses easily, so antistatic effect often can not be lasting.So the trend since the eighties is to adopt the latter to produce persistent anti-electrostatic polyester fiber.
Up to now, most in the past number average adopts the interior adding technology route of single type antistatic additive, with development or production anti-electrostatic polyester long filament.
The antistatic additive that belongs to this single type has poly-aryl to gather propyl sulfonic acid na phosphates, aliphatic alcohol polyoxyvinethene phosphate, 2,4 polyoxyethylene groups, 6 Aminocaproic Acid s-triazine, polystyrene sodium salt (80%) and polystyrene amine salt (20%) etc.Select the product of above-mentioned prescription gained in the market for use, the antistatic effect that has is not good, and the then durability that has is bad.Adopt in the aliphatic alcohol polyoxyvinethene phosphate as Japan Patent JP4736459 system to be added on prepared fiber in the polyester resin, though it antistaticly has a durability, effect is bad, fails to reach the technical indicator of making dust-free clothes and aseptic clothing.
The objective of the invention is to adopt the deficiency of adding antistatic additive in the single type, provide a kind of and can produce the high and durable polyester resin of antistatic efficient and the new technology of fiber thereof in order to overcome.
Main points of the present invention, it comprises the manufacturing and the fibre forming process of anti-electrostatic polyester resin, it is characterized in that adopting polyoxyethylene or polyether compound and alkylsulfonate or phosphate compounds to carry out the polyester resin of compound antistatic compounded technology and the technological process that long filament is produced.Belong to the compound antistatic additive of alkylsulfonate or phosphate and polyoxyethylene compound and be called CA type antistatic additive, polyethers or polyoxyethylene compounds are called CA-1 type antistatic additive, and alkylsulfonate or phosphate one compounds are called CA-2 type antistatic additive.
The proportioning of CA-1 type and CA-2 type has considerable influence to antistatic effect, make that CA-2 is fine to be contained among the CA-1 type, guarantees that the CA-1 type is arranged vertically and definite reasonable distribution ratio is vital.Following table 1 and table 2 are classified the test data of CA-1 type and the different additions of CA-2 type as.
By above-mentioned two tables as can be seen, when CA-1 type addition surpassed 6%, though antistatic effect increases, the condensate spinnability was poor, processing difficulties.When surpassing 10%, then can't process.
The content of CA-2 type fiber antistatic effect in 6% scope is remarkable, surpasses this and is worth then that antistatic effect does not have significant change, causes many, the processing difficulties of fiber lousiness on the contrary.
As fully visible, the CA-1 type is 3: 1～5: 4 with the ratio of CA-2 type, is preferably 5: 3.
Because the CA-2 type is dissolved in alcohol,,, generally after high vacuum, add more suitable in order to avoid take out of with the evaporation of methyl alcohol or ethylene glycol so the CA-2 type is not suitable for adding before polycondensation finishes.
The adding mode of CA-1 type is distributed with very big influence for it in fiber.Confirm according to the analysis of DDV viscoelastic instrument, reach the preceding adding of polycondensation before the ester exchange copolymerisation has all taken place, after polycondensation, add and then be the blend state.Concrete influence is as shown in the table.
Antistatic additive after composite can be deposited a period of time, also can composite immediately interpolation, can ester exchange polycondensation process adds or spinning before sneak in the terylene chips.It should be noted that, above-mentioned various adding method must guarantee that antistatic additive evenly distributes, be preferably in when polycondensation finishes and add, the percentage by weight that its consumption is pressed polyester resin or polycondensation material or ester exchange material calculates can be in the scope of 2-8%, be no more than 10% at most, otherwise can influence the mechanical-physical index of product.
In the ester exchange process, add in it in proportion as the additive after compound, then through polycondensation, granulation, drying, spinning, coiling, stretching, twisting, typing, winder, weave, arrangement, soap washing, wherein ester exchange, granulation, twisting, typing, winder, weave, put in order technology routinely.The improvement technical characterictic division of other each operation is as follows:
Polycondensation phase I elder generation's normal pressure 1.5～2.5 hours, 190～250 ℃ of temperature; Second stage low vacuum 2.5 hours, 250～280 ℃ of temperature, vacuum 0-760 torr; Phase III high vacuum 2～3 hours, 280 ℃ of temperature, especially the reaction end temperature is no more than 280 ℃ and is beneficial to antistatic additive and plays one's part to the full, and the vacuum residual voltage is less than 0.05 torr.
Dry is 760 torrs in vacuum, in 100～130 ℃ of scopes of temperature, and 24 hours time.
Spinning moulding processing can be carried out on common extruder type spinning machine, and temperature is 275～295 ℃, and winding speed is more than 600～1000 meters/minute.This is because anti-electrostatic polyester resin falls Jie easily than general terylene, so spinning temperature is unsuitable too high or overstand in spinning equipment.
Because the flowing temperature of anti-electrostatic polyester is lower, so draft temperature is unsuitable too high, generally drawing process is, 3.0～4.5 times of draw ratios, temperature of heat plate are 65～80 ℃, with 70 ℃ for well, hot plate temperature is 110～125 ℃, with 110 ℃ for well.
Arranging vertically in fiber in order to ensure antistatic additive, and be the fento distributions, in case the stop polarity group interferes with each other, bring into play maximum antistatic effect, is necessary so will select rational spinning, drawing process.Spinning silk winding speed height helps orientation in principle, but because CA-1 type flowing temperature is lower, so draft temperature is unsuitable too high, to prevent to be rolled state, generally selects draft temperature lower than ordinary polyester long filament draft temperature.
Fiber after the stretching adopts that normal polyester long filament technology is twisted, typing, winder get final product.
The fabric of fiber weaving of the present invention is soaped and is adopted neutral soap powder, and soap lye concentration is 1 grams per liter, and bath raio is 50: 1, and the time is 6 minutes, and temperature is 40 ℃, wash number 5 times, each 3 minutes.
Because the present invention adopts the technology that is added in the composite antistatic agent in the polyster fibre, so can make antistatic additive in the fiber process process, remain even distribution, be that antistatic additive exists with discontinuous phase, and keep even as far as possible and distance weak point, can avoid occurring in the fiber circuit high-order resistance like this, when the electric current in the entire circuit increased, the also corresponding quickening of electric charge loss had suppressed generation of static electricity and accumulation.Therefore, polyester filament and the fabric thereof produced with the present invention not only have durable antistatic behaviour, can be anti-standard wash more than 20 times, and have good antistatic efficient concurrently.Can discharge electric charge fast, be difficult for again electrifying, static friction voltage is all the time less than 200 volts, and the half-life, resistivity was less than 10 less than 60 seconds
10One centimetre of ohm, fracture strength extend 25 ± 7% greater than 2.7 lis of newton/dtexs.Fabric is not stained with ash, do not send out dirt, acidproof, well-pressed, can satisfy the specific (special) requirements of making dust-free clothes, aseptic clothing, anti-blast clothing, also be industry such as precision instrument, integrated circuit, computer make and application process in desirable supporting fibrous material.
