Description
Technical field
The present invention relates to terylene production field, relate in particular to a kind of take reclaim polyester and as raw material production, brighten whitening and brightening master batch of Regenerated Polyester Staple Fiber dimension and preparation method thereof.
Background technology
At present, Regenerated Polyester Fibres is with the feature such as its environmental protection, green, price competitiveness (comparing with primary trevira) be obvious, be subject to the support energetically of national all departments, and be developed rapidly, end 2011, the production capacity of recycled polyester has surpassed 7,500,000 tons, and wherein major part is to take the white regenerated polyester fiber that polyester bottle slice, polyester packaging material, primary polyester leftover etc. produce by the mode of simple interpolation white dyes as raw material.Because this kind of fiber exists larger difference with primary trevira in whiteness, in high-grade application field, still can not be applied on fibre product as raw materials such as single weaving, nonwovens.Major cause is wherein 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 in 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 conventional regeneration spinning is also not enough to meet the requirement of high-end fibre product to fibre whiteness, even if add titanium dioxide, still can not reach the object brightening.While being directly added on raw material convection drying toward contact meeting because of whitening agent, titanium dioxide, cause whitening agent and titanium dioxide premature oxidation to affect the whiteness of fiber and exist out airborne dust in the process of feeding intake to cause that titanium dioxide, whitening agent are wasted and the generation of contaminate environment phenomenon.
Chinese invention patent application (application number: 95111189.2, the applying date: the production method that 1995-09-08) discloses a kind of ultra-white terylene staple, the method is to make whitening agent to account for the fluorescent material of total amount 0.2 ~ 6% in polyester dacron section, production method and processing step: first fluorescent material and polyester slice are made to master batch in 5 ~ 30% ratio, then in total raw material, add that 4 ~ 20% master batches that prepare carry out drying moisture absorption, melt-spinning, packaging and warehousing after the coiling that oils, balance boundling, crimping by stretching, relaxation heat setting, cut-out.
Summary of the invention
The technical problem having 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, the polyester master particle of the present invention of take adds spinning in recycled polyester raw material to as raw material, can make the fiber that finally makes pure white as porcelain and gloss bright-coloured, whiteness exceeds primary trevira.Another object of the present invention is to provide the production method of above-mentioned polyester master particle.
In order to realize first above-mentioned object, the present invention has adopted following technical scheme:
For the production of a whitening and brightening polyester master particle that brightens regenerated terylene, this polyester master particle is made by the material and the polyester powder melt pelletization that comprise following component:
Component A: white dyes, brightener and thermo-stabilizer, the part by weight of white dyes, brightener and thermo-stabilizer is (20 ~ 90): (3-7): (3-7);
Component B: look female grade titanium dioxide for trevira;
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 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～0.3 μ m of titanium dioxide, and the massfraction of TiO2 is greater than 98%.
Choosing as an alternative, 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 polyethylene wax.
In order to realize second above-mentioned object, 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 appropriate component D, this mixture adopts twin screw extruder melt pelletization at 175～225 ℃ of temperature, makes 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 the there is blue light wave visible ray 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, effectively improves whiteness, glossiness and the vividness of regenerated polyester fiber or goods.At component A and component B certain in the situation that, along with the ratio of component C increases, the whiteness of the Regenerated Polyester Fibres that brightening mother particle is processed into increases gradually, and it is bright-coloured that color is also 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.Take polyester master particle of the present invention as raw material adds spinning in recycled polyester raw material to, can make the regenerated polyester fiber finally making have pure white as the effect of porcelain.
