According to the throat-tube type cold-wind-drafted and melt micro-fibre spinning device disclosed by the invention, production energy consumption is greatly reduced, energy is saved, and carbon emission is reduced.
Description
Technical field
The present invention relates to a kind of device for spinning, relate in particular to a kind of wikipedia type cold wind drawing-off melting microfiber device for spinning.
Background technology
Microfiber is the fiber that a kind of diameter is less than 5 microns, its spinning difficulty is higher, existing melt spinning device chamber adopts the melting method spinning of hot-air drawing-off, although these class methods can make melting microfiber, but its energy consumption is high, and because adopt high temperature (more than 200 DEG C) thermal current drawing-off, make the thermal stress of fibrous inside be difficult to eliminate, thereby the fiber softening of producing is poor, and the tensile strength of fiber is low.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of brand-new drawing-off principle, a kind of melting microfiber device for spinning that adopts cold wind drawing-off is provided, by the wikipedia type air drafting machine of special construction, resin under the molten condition that makes to flow out is through wikipedia type extension apparatus, the cold airflow of the drafted device of fiber inside is held and cooling rapidly, eliminate thermal stress in fiber to reach, fiber is stretched simultaneously.
Technical scheme: a kind of wikipedia type cold wind drawing-off melting microfiber device for spinning, specifically comprise: extruder, measuring pump, spinnerets, wikipedia type air drafting machine, receiving system and wrap-up, described extruder passes measuring pump by carrier pipe and connects spinnerets, described spinnerets is placed in described wikipedia type air drafting machine upper end, described spinnerets lower end is provided with spinning nozzle, described wikipedia type air drafting machine comprises upper and lower, between described top and bottom, there is the first gas channel, described lower central is the second gas channel, described receiving system is located under described the second gas channel, described wrap-up is positioned at described receiving system one side.
Described spinning nozzle is positioned at described wikipedia type air drafting machine center line top.
Described top is infundibulate.
Described spinnerets is upside-down triangle shape, and the spinning nozzle aperture of below is 0.1-1mm.
Described the second gas channel meets venturi principle.
Described the first gas channel and described the second gas channel vertical angle are 10 ~ 45 °.
The diameter of section of described the first gas channel and the second gas channel is 4 ~ 10mm.
Beneficial effect: disclosed a kind of brand-new wikipedia type cold wind drawing-off melting microfiber device for spinning, adopt special wikipedia type air drafting machine, resin the molten condition that makes to flow out from spinning nozzle is through special trunnion extension apparatus, fiber is held by the cold airflow at trunnion position and cooling rapidly, reach and eliminate thermal stress in fiber, the fused fiber that does not enter trunnion is stretched simultaneously, fineness requirement according to fiber regulates air quantity, thereby produce the fibrous material of different qualities requirement, energy consumption is low simultaneously, save the energy, reduce carbon emission.
