Specific embodiment
Invention is described in further detail below by specific embodiment.But it will be understood to those of skill in the art that under Row embodiment is merely to illustrate the present invention, and should not be taken as limiting the scope of the invention.
The present invention provides a kind of preparation method of high-performance sea-island fibre, by by Graphene and nano functional particle and the Prepared nano functional master batch after one island component is pre-dispersed, then be blended together with extra large component after uniformly mixing with the second island component Melt spinning, is made the sea-island fibre with specific function effect.
Nano functional particle, such as nano titanium oxide, nano zine oxide, nano kaoline, nano zircite, bamboo charcoal powder, Coffee carbon, negative ion powder, nano aluminium oxide, nano silicon oxide, nanometer basic zirconium phosphate silver, silver powder, copper powder and resistance to height Warm nature capsule of nano etc., with grapheme material (including ordinary graphite alkene and graphene oxide) and after compatilizer mixes with to benzene Dioctyl phthalate ethylene glycol fat (PET) and its derivative or polyamide (PA) and its derivative carry out melt blending, and functional agglomerate is obtained. Compatilizer is the material that a class can reduce the compatibility between polarity macromolecule and non-polar high polymer, in molecular structure generally Contain polar group and non-polar group.Graphene (nonpolar) can be effectively reduced with basic master batch by adding compatilizer Interfacial tension between (polarity), dispersion effect of the lifting Graphene in basic master batch.With terephthalate fat (PET) And its derivative or polyamide (PA) and its derivative are used as conducts such as island component, water-soluble polyester, polyvinyl alcohol and polypropylene Extra large component, blend melt spinning is carried out after functional agglomerate is uniformly mixed with island component with extra large component in dual-screw-stem machine, is passed through Cooling, drawing-off, dry, oil, the operation such as network, winding, it is final that the sea-island fibre with specific function is obtained.
Be added to nano functional particle in sea-island fibre by the present invention, fiber is had some special functions in itself, such as Antibacterial, anti-mite, mould proof, heat accumulation thermal, cool feeling and other effects, the effects such as may also be fiber there is far infrared, anion releasing.But Sea-island fibre is relatively thin in itself (< 0.05D), and mechanical performance is poor in itself for fiber, causes the mechanical performance of fabric finished product and rises Hair pilling property is poor, and the addition of nano functional particle certainly will more influence the mechanical performance of fiber.Therefore the present invention is adding Also appropriate Graphene is added while entering nano functional particle, the addition of Graphene can improve the mechanical performance of sea-island fibre, Reason be Graphene lamella network structure can with the material in island component formed composite structure, so as to lift island Fibre machinery performance.Sea-island fibre is by belonging to superfine fibre after fibrillation, it is strong that grapheme material sufficiently thin need to could lift fiber Power, but Graphene average thickness is thinner, will be more prone to aggregation, it is difficult to be uniformly dispersed, present invention discover that it is preferred that Graphene Average thickness is 20~50nm, close with nano functional particle diameter, by the effect of compatilizer, there is preferably synergy, Fiber has best mechanical performance.
