Abstract
The present invention relates to a manufacturing method of brightening mother particles for producing brightening polypropylene fiber, which comprises that a composite optical brightener is evenly mixed with fiber-grade polypropylene resin particles used as a base material, wherein the content of the composite optical brightener in the mixture is from 2 to 10 wt%; then, the mixture is blended, heated, melted and granulated by a screw extruder to obtain a brightening mother particle product, and a heating temperature is from 180 to 210 DEG C. The composite optical brightener comprises the following components: a component A: any one of dibenzoxazole, triazine-phenyl coumarin, naphtho-triazoles-phenyl coumarin or bis-(styryl) biphenyl; a component B: any one of anthraquinone or indigo; the weight proportion of the component A and the component B is A: B=100: 0.5 to 5. The present invention uses a novel brightening agent to replace usual copper phthalocyanine dye in the prior art to manufacture brightening polypropylene mother particles which are used as raw materials so as to cause the manufactured fiber to be more bright, and moreover, people have no feel of darkened luster.
Description
Technical field
The present invention relates to be used to produce the manufacture method of the brightening polypropylene mother particle of brightened polypropylene fibers, particularly the manufacture method of the brightening polypropylene mother particle of Cai Yong oxazole class and double styrene biphenyl fluorescent bleaches.
Background technology
Polypropylene fibre is cheap because of its cost of material, production technique is simple, fiber light weight, chemical-resistant resistance, series of advantages such as heat retention and hydrophobicity preferably, and its Application Areas constantly enlarges.Wherein brightened polypropylene fibers is the polypropylene fibre new variety of developing in recent years, and it is particularly suitable for making nonwoven fabric, dress ornament fabric and furnishing fabric, and this white fiber has higher added value relatively.Brightened polypropylene fibers is generally made by the master batch method, and in the prior art, brightening the acrylic resin that masterbatch generally adopts fibre-grade is base-material, and wherein Jia Ru oxazole class and double styrene biphenyl fluorescent bleaches are made by melt pelletization.In order further to improve whitening effect, also add an amount of phthalocyanine blue dyestuff as brightening agent usually, make the fiber that finally makes have blue light slightly.But the shortcoming that adds behind the phthalocyanine blue dyestuff is to make to brighten the sensation that looking of fiber has a kind of tarnish.
Summary of the invention
Technical problem to be solved by this invention provides a kind of brightening polypropylene mother particle manufacture method that is used to produce brightened polypropylene fibers, it adopts a kind of new brightening agent to replace the phthalocyanine blue dyestuff that uses in the prior art, making brightening polypropylene mother particle with present method is raw material, can make the fiber that finally makes pure whiter, gloss does not then have the sensation of deepening.
Below be the technical scheme that the present invention solves the problems of the technologies described above:
A kind of manufacture method that is used to produce the brightening mother particle of brightened polypropylene fibers, its process comprises a kind of composite fluorescence whitening agent with even as the fiber-grade pp resin mix particles of base-material, composite fluorescence whitening agent content therein is 2～10wt%, adopt screw extrusion press to carry out the granulation of blend heating and melting in this mixture then and obtain the brightening mother particle product, Heating temperature is 180～210 ℃, and the composite fluorescence whitening agent contains following component:
Component A: any in dibenzoxazine, triazine-phenyl coumarin, aphthotriazoles-phenyl coumarin or two-(styryl) biphenyl,
Component B: anthraquinone, any in indigo-blue,
The weight ratio of component A and component B is A: B=100: (0.5～5).
In granulation process, add an amount of dispersion agent, this will help the composite fluorescence whitening agent to be evenly dispersed in the spinning material particle, therefore the present invention's suggestion adds dispersion agent low-molecular polypropylene wax at the composite fluorescence whitening agent with as the fiber-grade pp resin mix particles of base-material the time again, and the add-on of dispersion agent is determined by following proportioning:
Composite fluorescence whitening agent: dispersion agent=1: (0.2～1.0) (weight ratio).Above-mentioned component A is preferably dibenzoxazine; Component B is preferably anthraquinone; The melt flow rate (MFR) of the fiber-grade pp resin base-material that is adopted is preferably 20～30g/10min.
In the present invention, component A is actually normally used white dyes, and component B is the selected brightening agent of the present invention.Selected and the add-on of brightening agent determine it is very crucial.We know that changes of shade is the reflection of material to the degree of photoabsorption and luminous reflectance (scattering).Brightening agent B 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 polypropylene fibre or goods in white saturating blue, color and luster is softer, effectively improves whiteness, glossiness and the vividness of polypropylene fibre or goods.The contriver finds that the weight ratio of component A and component B was greater than 100: 0.5, and brightening effect is not obvious, and when the weight ratio of component A and component B during less than 100: 5, blue reflected light is laid particular stress on, and gloss is deepening on the contrary.
Compared with prior art, making brightening polypropylene mother particle with present method is raw material, can make the fiber that brightens that finally makes have better glossiness and coloured light feature.
