Description
Technical field
The present invention relates to a kind of moisture absorption type polyester fiber and preparation method thereof.
Background technology
Polyester is typical thermoplastic synthetic fiber, since invention, due to its good mechanical strength, resistance to chemical reagents, heat resistance etc., has been widely used in fields such as dress material and industry purposes.
But, the hygroscopicity of polyester fiber is extremely low, when being used for direct contact skin or press close to the underwear, motion dress material etc. of skin dress, because skin is perspired and can not in time be discharged, can produce the sensation that is clamminess, poorer than natural fabric on snugness of fit, therefore limited the development of polyester fiber aspect the dress material purposes.
In order to improve the hygroscopicity of polyester, the most frequently used method is that copolymerization moisture absorption composition or interpolation have hygroscopic compound in polyester.Known copolymerization moisture absorption composition has the glycol that contains hydroxy alkylidene on side chain, the dicarboxylic acids that contains metal organic sulfonate etc.But, introduce above-mentioned moisture absorption composition on polyester backbone, can cause the intensity of polyester and weatherability to descend.
Can also hygroscopic compound be attached on polyester fiber to improve the hygroscopicity of fiber by chemical method in addition.For example graft acrylic acid or methacrylic acid on polyester fiber, recycle alkali metal replacement carboxyl wherein to improve the hygroscopicity of polyester fiber.But because hygroscopic compound is attached on fiber surface, low so there is the intensity temporal evolution, the problem such as feel, light resistance are bad.
Unexamined Patent 2-99612 communique disclose with hydroscopicity be hygroscopicity resin more than 10% as core, sheath section is with the core-sheath-type composite fibre of polyester coating.This method is when the heat treatments such as refining or dyeing, due to the hygroscopicity resin of core segment easily suction expand, thereby form crackle at fiber surface, due to hygroscopicity resin high and outside outflow to the dissolubility of water, hygroscopicity disappearance.
Japanese Patent Laid-Open 2000-8226 discloses a kind of moisture absorption polyester composite fiber, this fiber be constituent with polyethylene glycol copolyesters and polyvinylpyrrolidone as the core composition, conventional polyester makes by composite spinning method as the sheath composition.Although this method has solved the problem that core moisture expantion causes sheath section cracking, there is the shortcoming of hygroscopicity deficiency and moisture absorption poor durability in it.
Above-described method can improve to a certain extent the hygroscopicity of polyester fiber, but also exist various problems on using.
Summary of the invention
The object of the present invention is to provide a kind of moisture absorption type polyester fiber and preparation method thereof, use the polyester fiber that described method prepares still can keep the good characteristic of polyester fiber itself in the good hygroscopic while of acquisition.
Technical solution of the present invention is:
A kind of moisture absorption type polyester fiber mainly is made of polyester, and to contain with respect to weight polyester be 2～20% moisture absorption composition polyvinylpyrrolidone, and the average dispersion footpath of described polyvinylpyrrolidone is below 200nm.
Above-mentioned polyester is that polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate (PBT) or other contain the polyester of copolymer composition.
Moisture absorption composition in polyester fiber of the present invention is polyvinylpyrrolidone, and in order to obtain desirable moisture-absorption characteristics, containing in fiber with respect to weight polyester is 2～20% polyvinylpyrrolidone.With respect to weight polyester, when in polyester fiber, the content of polyvinylpyrrolidone was less than 2wt%, resulting polyester fiber did not have hygroscopicity; During greater than 20wt%, resulting polyester spinnability variation, fibrous physical property descends, contact has sticking sense, can't reach the requirement of snugness of fit.Preferred 5～the 15wt% of this content, more preferably 8～12wt%.
The average dispersion footpath of described polyvinylpyrrolidone in this fiber is below 200nm, below preferred 150nm.The average footpath that disperses can be so that the good complexing of polyvinylpyrrolidone and polyester below 200nm, thereby suppresses to mix the stripping of rear polyvinylpyrrolidone, prevents in use hygroscopicity variation of fiber.
The K value of above-mentioned polyvinylpyrrolidone is preferred 15～90, and more preferably 20～70.If the K value of polyvinylpyrrolidone is too low, even polyvinylpyrrolidone is not strong with the complexing power of polyester, easily stripping in Cooling Process, cause fiber to can not get good hygroscopicity after extruding.And if its K value is too high, the viscosity of polyester system increases greatly, mixingly spues badly, is difficult to granulation, causes production efficiency low.
The moisture absorption rate variance Δ MR of described fiber is 0.5～4%, and after this polyester fiber was processed through 130 ℃ of hot water in 30 minutes, wherein the dissolution rate of polyvinylpyrrolidone was below 3%, more preferably below 2%.Polyvinylpyrrolidone water-soluble fabulous, therefore the present invention is by being on two axle extruders more than 40 at draw ratio L/D, carry out the low temperature blend under vacuum condition, make the dispersion footpath of polyvinylpyrrolidone below 200nm, thereby improve the complexing power of itself and polyester, thereby the dissolution rate of polyvinylpyrrolidone in the reduction fiber, the hygroscopicity durability of raising fiber.
Moisture absorption type polyester fiber of the present invention has the mechanical property of general polyester fiber peer-level, and the strength and elongation of fiber is long-pending preferred more than 18.0, more preferably more than 20.0.Because polyvinylpyrrolidone is incompatible with polyester, it adds in polyester as the moisture absorption composition affects very large on the spinnability of polyester and the physical property of fiber.The present invention improves mouthful environment temperature of golden section cartridge heater during by spinning and improves the cooling condition of strand, thereby makes long-pending being greatly improved of strength and elongation of fiber, reaches the instructions for use of general dress material purposes.
Polyvinylpyrrolidone heat resistance at high temperature is relatively poor, makes the flavescence of resulting composition tone with the decomposes due to polyvinylpyrrolidone after polyester blend.Therefore, the present invention is by the mixing and low-temp spinning at low temperature, and the tone b value of the moisture absorption type polyester fiber that obtains is below 5.0.
