Description
Technical field：
The present invention relates to a kind of film dry-wet spinning machine, belong to synthetic fiber spinning technical field.
Background technology：
The chemical fibre spinning method that dry spinning is combined with the feature of wet spinning, also known as dry spray-wet spinning, referred to as dry
Wet spinning.This is the new spinning process that the sixties in 20th century grows up.Spinning solution first passes through one section of sky after spinning head extrusion
Between (3～100 millimeters, generally should be smaller than 20～30 millimeters), subsequently into coagulating bath.The gas in space can be air or other
Noble gases.Using during dry-wet spinning, stock solution thread can stand significant spinneret draft in atmosphere, and draw zone length is far super
Cross liquor stream to swell the length in area.The liquor stream axial deformation occurring in such distance, velocity gradient less, is actually swelling
Area does not have very big deformation.In contrast, during wet spinning, spinneret draft occurs in very short in the distance, and velocity gradient is very big, liquid
There is violent deformation in the stream area that swells, under less spinneret draft, strand will rupture.When therefore, using dry-jet wet-spinning
Jet stretch multiple and spinning speed can be improved.The spinning speed of dry-wet spinning, up to 600～1200 ms/min, more than wet spinning is
Height, and can be larger using aperture（φ=0.15～0.3 millimeter）Spinning head.And the concentration of spinning solution and viscosity then may be used
With high when the dry-spinning, can also relatively efficiently control the structure-forming process of fiber using dry-wet spinning.During dry-spinning, because by molten
The evaporation rate of agent is limited, and the setting rate of liquor stream is often very slow.During dry-wet spinning, the liquor stream being stretched（Fiber）Enter
Enter coagulating bath, setting rate and fibre structure can be temporarily transferred section coagulation bath composition and temperature and be changed in a wide range.Dry-
Though wet spinning has the advantage of dry-spinning and wet spinning concurrently, liquor stream easily along spray webbing head surface slug flow, causes spinning uneven, easily mixes
Silk.
Content of the invention：
The purpose of the present invention is to provide a kind of film dry-wet spinning machine for above-mentioned problem, can be prevented effectively from liquor stream edge
Spray webbing head surface cross flow, uniformly, spinning quality is good for spinning.
