Description
Technical field
The present invention relates to a kind of preparation method of chemical fibre, be specifically related to a kind of preparation method who adopts nanometer particle-modified chemical fibre.
Background technology
Nano particle has big specific area, surface atom number, surface energy and surface tension sharply increase with the decline of particle diameter, and small-size effect, skin effect, quantum size effect and macro quanta tunnel effect etc. cause nanoparticle to be different from conventional particle at aspects such as mechanical property, thermal property, magnetic performance, optical property and electric properties.Nano particle is joined in the chemical fibre, these functions can be imparted among the fiber, make nanometer particle-modified chemical fibre.Adopt the different nanoparticle of performance, can develop various functional fibers such as antibiotic, fire-retardant, anti-ultraviolet, far infrared, negative-oxygen ion health, antistatic and electromagnetic shielding, or improve the heat resistance or the mechanical property of fiber.
Prepare nano-material modified chemical fibre, the simplest method is exactly a finishing method.As:
Among the Chinese patent CN93114055 fabric panels such as cotton, fiber crops, silk, synthetic fiber are flooded in the solution of fluoride, organo-silicon compound, surfactant, adhesive, nano ceramics, water and other mixing, slough after the excessive solution 50～200 ℃ of dry down, typings, make have waterproof and dustproof, hate oil, the fabric of ultraviolet resistance; Be mixed with earlier the dressing liquid of nano-tourmaline particulate, far-infrared powder, emulsifying agent and adhesive among the Chinese patent CN00132606 by a certain percentage, then with this dressing liquid to fabric pad, coating or spray treatment, make fabric with health-care far infrared and negative oxygen ion function.
But above-mentioned back finishing technique exists the cohesion and the absorption stability problem of nanometer ultrafine particle, and the fabric of handling can influence its function of use because of washing.Prepare the permanent function nona modified fiber, will be with nano-particles filled in fibrous inside.
In fibrous inside, Chang Yong method is the co-blended spinning method the most with nano-particles filled, comprises melt blending spin processes and solution blending spin processes.
The melt blending spinning is earlier nano particle to be dispersed in the polymer melt, carries out spinning, drawing-off then on traditional spinning equipment, makes nanometer particle-modified fiber, and need not to increase miscellaneous equipment.As among the Chinese patent CN01108688 surface treated nano particle and polyethylene terephthalate being carried out common grinding in the special reaction device, then by a certain percentage with the polyethylene terephthalate melt blending, the preparation polyethylene terephthalate/nano-composite fiber; Among the Chinese patent CN02111209 polyester or modified poly ester and promoter, nano-powder tertiary blending melt-spun are made anti-electrostatic nano compound polyester fibre.
Because nano particle very easily reunites, the polymeric matrix melt viscosity is bigger again, so depends merely on the mechanical blending effect in the said method and be difficult to make nano particle to reach nanoscale in polymeric matrix to disperse, thereby influences spinning, the tensile property of blend.
The solution blending spinning is earlier nano particle to be dispersed in the spinning solution, carries out spinning again, desolvates, draft process makes nanometer particle-modified fiber.As earlier nano particle being carried out being dispersed in the spin solvent of ultra high molecular weight polyethylene (UHMWPE) after the surface treatment among the Chinese patent CN02148597, adding the UHMWPE powder then carries out swelling, dissolves and make spinning solution, carry out spinning again, stretch and make nanometer particle-modified UHMWPE fiber, the mechanical moduli of this fiber can improve 20～70% on the original basis.The nano-powder material that will have correlation function among the Chinese patent CN01128377 evenly is blended in the artificial viscose solution carrier, handles through the spray silk and makes the functional artificial viscose that human skin is had regulating action.
Because nano particle is very easily reunited, even after surface treatment and ultrasonic strong dispersion, the aggregate that also has nano particle unavoidably is present in the spinning solution, thereby influences its spinnability and draftability.
In order effectively to solve the even scattering problem of nano particle in the polymer body, people have proposed the compound new method of in-situ polymerization, promptly on the nano particle of polymolecularity, be written into component, and then on this nanoparticle surface, carry out polymerisation and prepare in-situ composite with catalytic activity.As disclosing the nanocomposite of a kind of polyolefin and clay among Chinese patent CN1255510A and the U.S. Pat P6444742, this composite is made up of the polyethylene of 40～99.9 heavy % and the fiber rod stone kind clay of 0.1～60 heavy %, transistion metal compound with the nanoscale clay is a catalyst, with the organo-aluminum compound is co-catalyst, carry out the in-situ polymerization of alkene, prepared composite has excellent mechanical property and hot property.Chinese patent CN01142857 discloses a kind of preparation method of nano composite polyester, be mixed with earlier the mixed liquor of nano zine oxide, nano barium sulfate, ethylene glycol and terephthalic acid (TPA) by a certain percentage, add catalyst and stabilizing agent then and carry out polymerization, discharging, make nano composite polyester.The in-situ polymerization composite algorithm can make nano particle be dispersed in the polymeric matrix uniformly, but this method is comparatively loaded down with trivial details, and the cost of gained composite is higher, and the spinning properties of gained nano composite polymer awaits further to study.
Summary of the invention
The technical issues that need to address of the present invention are the preparation methods that disclose a kind of comparatively easy nanometer particle-modified chemical fibre, to overcome the above-mentioned defective that prior art exists, satisfy the needs in relevant field.
Technical conceive of the present invention is such:
The fiber that reaches of the present invention is limited to wet method or dried wet method spins the fiber that forms, be characterized in surface treated nano particle is joined by a certain percentage the coagulating bath of wet spinning or dry-wet spinning, in pre-heating bath or the extraction bath, carrying out high-speed stirred disperses and ultrasonic dispersion certain hour, the homodisperse body lotion of preparation nano particle, to substitute the coagulating bath of wet spinning or dry-wet spinning, pre-heating bath or extraction bath, make nano particle diffuse into fiber by means of diffusion and desolventize in the micropore that the back forms, postprocessing working procedures such as stretched is then made the homodisperse fiber of nano particle.Can be made into according to the difference that adds nano particle have antibiotic, fire-retardant, anti-ultraviolet, various functional fibers such as far infrared, negative-oxygen ion health, antistatic and electromagnetic shielding, or improve the heat resistance and the mechanical property of fiber.
