Abstract
The present invention relates to a resin mixture for manufacturing a polypropylene fiber modified fine denier filament and a super fine denier filament and a blending method thereof. The resin mixture is formed by directly blending polypropylene with controllable rheological properties, copolymerized polyester, etc. The fine denier filament of which the monofilament fineness is from 0.3 to 1.3 dtex, and the super fine denier filament can be prepared by the resin mixture. The fiber which is spun can be dyed by dispersion dye sold in the market at normal pressure, and the moisture absorption rate of a fabric is higher than that of terylene, which conforms to the processing requirement of fabrics comprising sportswear, underclothes, spring and autumn face fabric, etc.
Description
The present invention relates to be used to make the resin compound and the blend method thereof of polypropylene fibre modification fine denier filament and superfine denier fiber.
The fiber of producing by plain polypropylene as take fibrous material because of stainability, hygroscopicity is relatively poor and the sense of fabric wax shape fails to obtain extensive use for a long time.In recent years, because with the thin dawn of special processing method production and the development of super fine denier (filament number is less than 1 dtex) polypropylene fibre, thereby give the significant saturating wet perspiration discharging performance of polypropylene fabric and be widely used in underclothes, as high-grade gym outfit, underwear and spring and autumn clothing lining.Yet the method that present polypropylene fibre all adopts the interpolation Masterbatch to prepare coloured remedies the defective that polypropylene fibre is difficult to dye, and commercially available acrylic resin can only spin the fiber of filament number greater than 1.3 dtexs with general spining technology.
According to JP02,191,719 reports, the composite fibre of the copolymer (CDPET) of general fibrous polypropylene and sodiosulfoisophthalic acid-terephthalic acid (TPA), after alkali treatment, dissolve the CDPET component, can make the superfine fibre that filament number is 0.22d, as filtration fabrics, this invention does not relate to the application that blending type is taken fiber.
The present invention will control blending and modifyings such as the controllable rheology acrylic resin of polymer streams sex change and CDPET with molecular-weight adjusting, make its prepared fiber have the disperse dyes stainability.Because the polypropylene modified fiber filament number that the present invention makes is 0.3～1.3 dtex, thereby make fabric have the good wicking effect, present significant saturating wet perspire, more opened up the Application Areas of polypropylene fibre, can be used as top grade and take fibrous material, even surpass some natural fabric.
Technical essential of the present invention is: a kind of polypropylene modification resin, form by polypropylene and one or more other resins, described polypropylene is the resin with controllable rheology, its melt index 〉=20 restrain/10 fens, inherent viscosity [η] is 1.25～1.55, and described other resins are that inherent viscosity [η] is that 0.5～0.61 sodiosulfoisophthalic acid and copolyester, ethylene-vinyl acetate copolymer and the ethylene-acrylic acid copolymerization zinc salt of terephthalic acid (TPA), the percentage by weight of its prescription are:
Polypropylene 80～95
Copolyester 5～20
Ethene-acetate ethylene copolymer 0～7
Ethene-acrylic copolymer zinc salt 0～4
The optimum formula of polypropylene modification resin is made up of the controllable rheology polypropylene of weight ratio 90% and 10% sodiosulfoisophthalic acid and terephthalic acid (TPA) copolyester.
The optimum formula of polypropylene modification resin is made up of the controllable rheology polypropylene of weight ratio 85%, 10% sodiosulfoisophthalic acid and the ethylene-vinyl acetate copolymer of terephthalic acid (TPA) copolyester and 5%.
The optimum formula of polypropylene modification resin is made up of the controllable rheology polypropylene of weight ratio 80%, 19% sodiosulfoisophthalic acid and the ethylene-acrylic acid copolymer zinc salt of terephthalic acid (TPA) copolyester and 1%.
The production method of polypropylene modification resin of the present invention is to be delivered in the double screw extruder fusion under 270 ℃ of temperature, Cast Strip and pelletizing by weight with after the direct blend of above-mentioned resin.
With above-mentioned polypropylene modification resin slicer melt spinning, spin under the speed at 400～1100 meters/minute, stretch 3～5 times between room temperature to 120 ℃, can be made into fine denier filament and superfine denier fiber that stainability and filament number are 0.3～1.3 dtex.
Compare prior art, the present invention has following advantage:
The present invention altogether the fiber that spinned of warm modified polypropylene resin can carry out dyeing at normal pressure with commercially available DISPERSE DYES, have good color tone.Measured by colour photometer, with Disperse Red 3B dyeing, the KS value brings up to 3.61 by 0.63 of virgin pp, and to disperse blue 2BLN dyeing, the KS value brings up to 6.40 by 0.62.
2. the fiber that when containing the CDPET of 10% weight ratio in the modified resin, spins, after alkali treatment, polyacrylic hygroscopicity can bring up to 0.521% by original 0.02%, than hygroscopicity 0.4% height of terylene, and has overcome the wax shape sense of polypropylene fibre fabric to a certain extent.
3. to spin the fibre single thread fiber number that the super drawing method produces be 0.3～1.3 dtex by common in the present invention, intensity 〉=4 newton/dtex, degree of stretching≤60%.Meet sweat shirt, underwear and spring and autumn fabric processing request such as lining.
Below the present invention is further elaborated by three examples:
Example one:
The CDPET section was dried 48 hours in 100 ℃ under the vacuum of 760mmHg post, with 90: 10 weight ratios with above-mentioned controllable rheology polypropylene and CDPET mixed after, under 270 ℃, melt blending and the granulation of system band in Branbender ZSK 30M9/II double screw extruder.Blending extrudant is observed under ESEM, for having equally distributed fento-matrix structure (seeing photo), the maximum particle diameter of CDPET decentralized photo＜3 micron, melt-spun under 400 meters/minute, making intensity 〉=4 newton/dtex, degree of stretching≤80%, fiber number is the fiber of 0.7 dtex.
Example two:
CDPET ethylene-vinyl acetate copolymer after above-mentioned controllable rheology polypropylene and the vacuumize is mixed with 85: 10: 5 weight ratios, is with granulation at Branbender ZSK 30M9/II double screw extruder melt blending and system under 270 ℃.The blending extrudant that obtains is observed under ESEM, has uniform distribution (photo 2), the maximum particle diameter of decentralized photo＜2.3 micron, and the fiber number that makes fiber is 1 dtex.
Example three:
CDPET ethylene-acrylic acid copolymer zinc salt after above-mentioned controllable rheology polypropylene and the vacuumize was with weight ratio blend granulation in 80: 19: 1, the blending extrudant that is obtained is observed under ESEM, its blend be improved (photo 3) that distribute, decentralized photo maximum particle diameter＜2 micron, the fiber number that makes fiber is 1.3 dtexs.
