Technical field
The present invention relates to fibre in differentiation field, refer to the Super-fine Synthetic Leather fiber that a kind of Graphene strengthens especially.
Background technology
Superfine fibre is often referred to fiber number 0.3 dawn (diameter 0.5 micron) fiber below, is widely used, occupies an important position in national economy.Superfine fiber chemical leather is a kind of composite grown up based on sea-island composite fiber, and it is the third generation synthetic leather that most probable substitutes corium, is widely used in footwear, ball, the field such as sofa, case and bag.Superfine fiber chemical leather is all rapidly developed at home, outward.Nearly 100,000,000 meters of the output that only superfine fiber chemical leather 2014 is domestic.
Current superfine fiber chemical leather industry many employings PA6 makes island component and carries out islands-in-sea type fibre spinning.PA6 superfine fibre after islands-in-sea type fibre decrement has excellent performance in a lot, but also there is shortcoming, such as: easily produce that electrostatic, fracture strength are high not enough at special occasions, goods are easily mouldy etc. after arranging.
Graphene is a kind of two-dimension nano materials, is only made up of the mono-layer graphite sheet of an atomic layers thick.Because the mechanics of the two-dimentional lamellar structure of its uniqueness and excellence, electricity and physical characteristic make it have application prospect widely in thermoelectric fiber reinforced composite, nano electron device and sensor manufacture etc.Its high mechanical strength, outstanding conduction and heat conductivility become desirable Nano filling for the enhancing of polymer composites performance and expansion.
Summary of the invention
Main purpose of the present invention is the shortcoming overcoming prior art, the Super-fine Synthetic Leather fiber that a kind of Graphene strengthens is provided, it has the performances such as fracture strength is high, antistatic, antibacterial, ageing-resistant, pliability is strong, can improve the combination property of superfine fiber chemical leather for the synthesis of leather industry, and available traditional islands-in-sea type fibre spinning equipment is produced.
The present invention adopts following technical scheme:
By preparing nylon 6 masterbatch of graphene-containing, then masterbatch being added in nylon 6 and carrying out island melt spinning, decrement obtains superfine fibre, preparing especially by following steps:
A. by Graphene and nylon 6 by weight 1:10-20 by double screw extruder mix extrude cool, nylon 6 masterbatch of preparation graphene-containing;
B. by metering device by weight ratio (nylon 6 masterbatch of graphene-containing: nylon 6): the ratio of sea component=(2-3:48-47): 50 carries out islands-in-sea type fibre melt spinning;
C. islands-in-sea type fibre is carried out the Super-fine Synthetic Leather fiber that decrement obtains Graphene enhancing.
Graphene is Graphene or graphene oxide.
Double screw extruder mixing extrudes each district temperature for (40-120-160-180-220-270-275-285-285) DEG C ± 5 DEG C, extruder head temperature 280 ± 5 DEG C.
Cooling, granulation be in water cool, section, at (-0.05 to-0.07) MPa(105 to 115) DEG C condition under vacuumize 3-6 hour.
Islands-in-sea type fibre spinning is divided into by islands-in-sea type fibre structure determines island composite spinning or indefinite island co-blended spinning.
Sea component is PE, COPET or WSPU (water soluble polyurethane).
Determining island composite spinning is conventional composite spinning technology, namely respectively hang oneself after sea component and island component drying after screw extruder extruding, melting, metering through filament spinning component spinning, oil after cooling forming, coiling, then boundling, drawing-off, curling, sizing, severing obtains staple fibre.
Indefinite island co-blended spinning is conventional co-blended spinning technique, namely measures after sea component and island component drying, mixes, and through filament spinning component spinning after screw extruder extruding, melting, oils after cooling forming, drawing-off, curling, sizing, severing obtain staple fibre.
Islands-in-sea type fibre carries out decrement for adopt toluene decrement, Alkali reduction and Alkali reduction mode to carry out decrement respectively according to sea component material PE, COPET and WSPU.
From the above-mentioned description of this invention, compared with prior art, the present invention has following beneficial effect:
1, superfine fibre of the present invention uses Graphene enhancing to have the performances such as fracture strength is high, antistatic, antibacterial, ageing-resistant, pliability is strong, can improve its quality and combination property for superfine fiber chemical leather.
2, Super-fine Synthetic Leather fiber of the present invention uses traditional islands-in-sea type fibre spinning equipment to produce, and can accomplish scale production.
