Abstract
The invention relates to the field of terylen production, particularly a whitening/brightening master batch for producing whitened regenerated terylen chopped fibers from recovered polyester and a preparation method thereof. The whitening/brightening master batch for producing whitened regenerated terylen is prepared by melting and granulating the following components and polyester powder: component A: fluorescent whitening agent, brightener and heat stabilizer; component B: color master batch titanium dioxide for polyester fibers; and component C: brightening agent. The component A:component B:component C weight ratio is (1%-15%):(15%-45%):(0.1%-1.0%). The invention provides a whitening/brightening master batch for producing whitened regenerated terylen.
Description
Technical field
The present invention relates to the terylene production field, relate in particular to a kind of whitening and brightening master batch that brightens the Regenerated Polyester Staple Fiber dimension take the recovery polyester as raw material production and preparation method thereof.
Background technology
At present, Regenerated Polyester Fibres is with the characteristics such as its environmental protection, green, price competitiveness (comparing with primary trevira) be obvious, be subject to the energetically support of national all departments, and obtained fast development, end 2011, the production capacity of recycled polyester surpasses 7,500,000 tons, and wherein major part is the white regenerated polyester fiber of producing by the mode of simple interpolation white dyes take polyester bottle slice, polyester packaging material, primary polyester leftover etc. as raw material.Because there is larger difference with primary trevira in this kind fiber in whiteness, still can not be applied on the fibre product as raw materials such as single weaving, nonwovens in the high-grade application field.Major cause wherein is that the whiteness of Regenerated Polyester Fibres and the whiteness of primary trevira also exist larger difference.In view of the regenerated fibre market of competition, how by improving the whiteness of fiber, reduce primary polyster fibre and the regenerated terylene difference on whiteness, the added value and the produce market share that improve reconstituted product are the only way which must be passed of regenerated terylene development.The regenerative polyester staple fiber that brightens that directly adds whitening agent production with respect to the conventional regeneration spinning also is not enough to satisfy high-end fibre product to the requirement of fibre whiteness, still can not reach the purpose that brightens even if add titanium dioxide.When the contact meeting directly is added on the raw material convection drying because of whitening agent, titanium dioxide, cause whitening agent and titanium dioxide premature oxidation to affect the whiteness of fiber and exist airborne dust in the process that to feed intake to cause the generation of titanium dioxide, whitening agent waste and contaminate environment phenomenon.
Chinese invention patent application (application number: 95111189.2, the applying date: 1995-09-08) disclose a kind of production method of ultra-white terylene staple, the method is to make whitening agent with the fluorescent material that accounts for total amount 0.2 ~ 6% in the polyester dacron section, production method and processing step: first fluorescent material and polyester slice are made master batch in 5 ~ 30% ratio, add in total raw material again that 4 ~ 20% master batches that prepare carry out drying moisture absorption, melt-spinning, packaging and warehousing behind the coiling that oils, balance boundling, crimping by stretching, relaxation heat setting, cut-out.
Summary of the invention
The technical problem that has occurred in order to have solved direct interpolation.An object of the present invention is to provide a kind of whitening and brightening polyester master particle for the production of brightening regenerated terylene, add spinning in the recycled polyester raw material to take polyester master particle of the present invention as raw material, can make the fiber that finally makes pure white bright-coloured such as porcelain and gloss, whiteness exceeds primary trevira.Another object of the present invention provides the production method of above-mentioned polyester master particle.
In order to realize first above-mentioned purpose, the present invention has adopted following technical scheme:
A kind of whitening and brightening polyester master particle for the production of brightening regenerated terylene, this polyester master particle is made by the material that comprises following component and polyester powder melt pelletization:
Component A: white dyes, brightener and thermo-stabilizer, the part by weight of white dyes, brightener and thermo-stabilizer are (20 ~ 90): (3-7): (3-7);
Component B: trevira look female grade titanium dioxide;
Component C: brightening agent; Brightening agent is blue or green blue according to (5-25) by ultramarine violet, reactive brilliant bule and phthalein: (10-40): part by weight (30-60) mixes formation;
Above-mentioned component A, B, the weight ratio of C are A:B:C=(1%～15%): (15%～45%):
Above-mentioned component A, B, the gross weight of C can account for polyester master particle gross weight 10% ~ 90%, specifically can adjust according to follow-up service requirements.Preferably, be 30 ~ 70%.
As preferably, above-mentioned component A, B, the weight ratio of C are A:B:C=(3%～10%): (30%～45%):
As preferably, above-mentioned white dyes is selected one or both in two (5 methyl-2-benzoxazolyl) toluylene of 4.4-and the diphenylethyllene dibenzoxazine.
As preferred again, above-mentioned white dyes is selected two (5 methyl-2-benzoxazolyl) toluylene of 4.4-and two kinds of mixing of diphenylethyllene dibenzoxazine, and the part by weight of two (5 methyl-2-benzoxazolyl) toluylene of described 4.4-and diphenylethyllene dibenzoxazine is (20-55): (5-35).
As preferably, above-mentioned titanium dioxide is selected anatase titanium dioxide, the particle diameter 0.2 μ m of titanium dioxide～0.3 μ m, and the massfraction of TiO2 is greater than 98%.
As an alternative choosing, above-mentioned pigment is by the some or all of alternative ultramarine violet of ultramarine, the some or all of alternative reactive brilliant bule of EX-SF DISPERSE BLUE EX-SF 300.
As preferably, this polyester master particle also comprises dispersion agent, and dispersion agent accounts for 0.5%～3% of polyester master particle weight.As preferably, dispersion agent is selected one or both mixing in ethylene bis stearic acid amide and the polyethylene wax.
In order to realize second above-mentioned purpose, the present invention has adopted following technical scheme:
A kind of preparation method who prepares above-mentioned polyester master particle, the method is got component A, component B, component C and polyester powder by required proportioning and is put into high-speed mixer and stir, mix, add during this time an amount of component D, this mixture adopts twin screw extruder melt pelletization under 175～225 ℃ of temperature, makes the master batch product.
The present invention is owing to having adopted above-mentioned technical scheme, brightening agent C component of the present invention can more effectively absorb UV-light (wavelength 360～380nm), and convert thereof into and have the blue light wave (visible light of wavelength 450～500nm), its luminous reflectance factor is very high, bright in colour, thereby make regenerated polyester fiber or goods white in thoroughly blue, color and luster is softer, the whiteness of Effective Raise regenerated polyester fiber or goods, glossiness and vividness.In the situation that component A and component B are certain, along with the ratio increase of component C, the whiteness of the Regenerated Polyester Fibres that brightening mother particle is processed into increases gradually, and it is bright-coloured that color also is tending towards.But its content is increased to
When above, blue reflected light is laid particular stress on, and gloss is dimmed on the contrary.Add spinning in the recycled polyester raw material take polyester master particle of the present invention as raw material to, can make the regenerated polyester fiber that finally makes have pure white effect such as porcelain.
