Specific embodiment
Invention is described in further detail below by specific embodiment.But under it will be understood to those of skill in the art that
Column 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
Obtained nano functional master batch after one island component is pre-dispersed, then be blended together with extra large component after evenly mixing with the second island component

Nano functional particle, as nano-titanium dioxide, 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., after being mixed with grapheme material (including ordinary graphite alkene and graphene oxide) and compatilizer and to benzene
Dioctyl phthalate ethylene glycol rouge (PET) and its derivative or polyamide (PA) and its derivative carry out melt blending, and functional agglomerate is made.
Compatilizer is a kind of substance that can reduce the compatibility between polarity macromolecule and non-polar high polymer, in molecular structure usually
Contain polar group and non-polar group.Graphene (nonpolarity) and basic master batch can be effectively reduced by the way that compatilizer is added
Interfacial tension between (polarity) promotes dispersion effect of the graphene in basic master batch.With terephthalate rouge (PET)
And its derivative or polyamide (PA) and its derivative are as conducts such as island component, water-soluble polyester, polyvinyl alcohol and polypropylene
Functional agglomerate and island component are carried out in dual-screw-stem machine with extra large component blend melt spinning after evenly mixing, passed through by extra large component
Cooling drawing-off, is dried, is oiled, the processes such as network, winding, final that the sea-island fibre with specific function is made.
Nano functional particle is added in sea-island fibre by the present invention, has the function of fiber itself some special, such as
Antibacterial, anti-mite, mould proof, heat accumulation thermal, cool feeling and other effects can also be fiber with far infrared, release anion and other effects.But
Sea-island fibre itself is relatively thin (< 0.05D), and fiber mechanical performance itself is poor, leads to 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 suitable graphene is added while entering nano functional particle, the addition of graphene can improve the mechanical performance of sea-island fibre,
Reason is that the lamella reticular structure of graphene can form the structure of composite material with the substance in island component, to promote island
Fiber mechanical performance.Sea-island fibre belongs to superfine fibre after fibrillation, and it is strong that grapheme material sufficiently thin need to could promote fiber
Power, but graphene average thickness is thinner, will be more easier to assemble, it is difficult to it is 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 preferable synergistic effect,
Fiber has best mechanical performance.
