Abstract
The present invention relates to a production method of super fine fibre, in particular it relates to a production method of colored functional super fine fibre. Said production method includes the following several steps: directly mixing super fine fibre raw material with coloring material, adjuvant and functional additive according to a certain mixing ratio to obtain colored anti-bacterial mother materi, melting said mother material at high temperature, extruding said molten mother material by using twin-screw extruder and making basic hydrolysis so as to obtain the invented product.
Description
Technical field:
The present invention relates to the production method of superfine fibre, relate in particular to the production technology of coloured functional superfine fibre.
Background technology:
The approach that general textiles obtains color has:
1. textile dyeing arrangement;
2. the processing of weaving again after the stock-dye;
3. the processing of weaving again behind the yarn dyeing.
Generally speaking the superfine fibre dyeability is very poor, can dye with disperse dyes, but just can carry out under the condition that needs High Temperature High Pressure or carrier to exist usually, big to fibre damage, COLOR FASTNESS is poor, and the dyeing spectral range is narrow, these dyeing courses of what is more important all produce a large amount of three wastes, the serious harm environment.
Someone wishes to obtain coloured fiber by the method for modification.Yet for synthetic fiber, because its molecular structure densification, dye molecule is difficult for entering the inside of fiber, and most of synthetic dyeings are all very difficult.In order to improve the dyeability of synthetic fiber, the researcher changes the chemistry tissue and the internal structure of synthetic fiber by the method for monomer copolymerization, polyblend or block copolymerization, reaches chromatophilous purpose.But this method cost is too high, and is too narrow to the selection face of fibrous material, equally also contaminated environment.
In the production technology of existing superfine fibre, general all is that the additive and the dyestuff of functionalization are handled in two steps, the additive that before spinning, adds functionalization, dye at dyeing and finishing process, not only increased production cost, and produce serious three wastes problem, therefore, realize that the production technology and the industrialization thereof of superfine fiber one-step functional has crucial meaning.
Meaning of the present invention and advantage:
1. product function variation.Can add the nano-antibacterial particle of difference in functionality;
2. save the dyeing difficult problem of subsequent handling, shorten the technological process of production of product, reduce production costs;
3. improve the dyeing COLOR FASTNESS, COLOR FASTNESS, vividness, fibre strength height, coloured yarn of production is compared superior with normal dyeing, and product can be used for producing high-grade garment material;
4. increase varieties and designs;
5. be beneficial to environmental protection, eliminated the severe contamination that stock-dye causes to environment, reduce three-waste pollution, and be beneficial to environmental protection, this technology is regarded as the significant innovation to traditional dyeing technology, has the huge social benefit.
Summary of the invention:
The purpose of this invention is to provide a kind of dyeing and finishing process that saves, reduce production costs, reduce three-waste pollution, be easy to industrial functionalization super-fine fiber material and production technology thereof.
Superfine fiber one-step functional producing method, it comprises following steps:
(1) the raw material mixed melting is made fibrous material,
(2) fibrous material is peeled off by alkali hydrolysis method, obtain super-fine fiber material, its detailed process is: fine fibre raw material and dyestuff, auxiliary agent and functionalized directly are mixed and made into the coloured anti-bacterial masterbatch, the coloured anti-bacterial masterbatch fusion at high temperature that obtains, effect by double screw extruder (going up the accurate spinning extruder of XD-bimetallic that Hisoon reaches rubber and plastics machine Manufacturing Co., Ltd), make fibrous material after alkali hydrolysis method is peeled off, obtain the superfine fibre of diameter between 100 nanometers～1 micron.Wherein count by weight percentage, high molecular superfine fiber accounts for 96%～99.9% of material gross weight, and dyestuff, auxiliary agent and additive account for 0.05%～1%, 0.03%～1% and 0.02%～2% of material gross weight respectively.
The detailed process of above-mentioned superfine fiber one-step functional producing method also can adopt following process: the raw material of getting above-mentioned weight ratio, then with the fine fibre raw material high-temperature fusion, under molten condition, spin by double screw extruder simultaneously and after fully mixing with dyestuff, auxiliary agent and functionalized, peel off by alkali hydrolysis method then, obtain the superfine fibre of diameter between 100 nanometers～3 micron.
Described fine fibre raw material is selected from a kind of in polyester, the polyamide-based macromolecule, or wherein two or more polyester, polyamide-based high molecular blend, and the diameter of high molecular superfine fiber is between 10 nanometers～3 micron.
The polyesters macromolecule is selected from a kind of in polyethylene terephthalate, the polybutylene terephthalate (PBT) in the described high molecular superfine fiber mixture; Described polyamide-based macromolecule is selected from a kind of in nylon 6, the nylon 66.
Described functionalized is a nano antibacterial agent.Wherein nano antibacterial agent is selected from a kind of in the following material: contain a kind of inorganic nanoparticles in silver ion, zinc ion or the copper ion; Or contain a kind of inorganic zeolite nano particle in silver ion, zinc ion or the copper ion; Or one or more the combination in Zinc oxide nanoparticle, zinc sulfate nano particle, titania nanoparticles and the copper sulphate nano particle; Or chitin, chitosan nano particle, its granularity is all less than 1 micron.
Described dyestuff is selected from a kind of in vinyl sulfone(Remzaol/chloro-s-triazine, a vinyl sulfone(Remzaol/fluorine s-triazine, the two chloro-s-triazine double-active radical dye.
Described auxiliary agent comprises paraffin or atoleine, and auxiliary agent disperses dyestuff as surfactant easily.
Alkali hydrolysis method in the superfine fiber one-step functional producing method is called the chemical stripping method again, be a kind of in used three kinds of methods of peeling away in the fibre of polyester-nylon composite superfine fibre, two kinds of methods are respectively Mechanical Method and swelling method in addition, and these three kinds of methods all can reach the effect that reduces fibre diameter.Alkali hydrolysis method is to utilize two kinds of components of composite fibre all can be quickened the mechanism of hydrolysis by alkali, hydrolysis takes place in the interface of composite fibre two components in buck (or adding some promoter again) solution, weaken bonding force, make it to be easy to peel off, reach out fine purpose, thereby obtain the superfine fibre between 0.1 micron～several microns.
Technology of the present invention and production method compared with prior art have the following advantage:
1) superfine fiber one-step functional production technology provided by the invention is that fine fibre raw material and dyestuff, auxiliary agent and functionalized directly are mixed and made into the coloured anti-bacterial masterbatch, or master batch forms superfine fibre by the double screw extruder spinning simultaneously and after fully mixing with dyestuff, auxiliary agent and functionalized under the state of fusion, one step of technology that original several steps finish is finished, saved production cost greatly.
2) superfine fiber one-step functional production technology provided by the invention not only contains dyestuff, also contain the silver in many nanometers duct or the inorganic nanoparticles of zinc or copper ion, or the inorganic zeolite nano particle in many nanometers duct of argentiferous or zinc or copper ion, or one or more the mixture in the zinc oxide, zinc sulfate, titanium dioxide, copper sulphate nano particle, or chitin, chitosan nano particle, therefore its granularity all has significant antibacterial functions all less than 1 micron.
