Description
Technical field
The utility model relates to synthetic fiber spinning production equipment technical field, is specifically related to a kind of ring blowing air cartridge for synthetic fiber spinning.
Background technology
During melt spinning, melt is from the pore ejection of spinnerets, through cooling, stretching final set becomes strand, from spinning plate surface to winding part, can be divided into three parts by spinning journey, it is mobile geodetic deformation district, oriented crystalline district and plastic deformation district, strand process of setting is quite complicated, on edge, spin each particle of journey, its movement velocity, diameter, sectional area, temperature, viscosity, stressed and the internal structure of institute is all constantly changing, and these factors are to influence each other, because melt temperature is high a lot of compared with ambient air temperature, micro Denier strand is very delicate again, environment is very responsive to external world, therefore environmental change meeting has influence on the uniformity of as-spun fibre quality immediately, as the intensity of fiber, elongation.And melt itself is inhomogeneous, the fluctuation of spinning temperature, pump is for the fluctuation of amount, the variation of winding speed and cooling forming condition are very important factors, due to the state of air with flow and be easy to change, along with spining technology is to micro Denier porous high speed future development, it is particularly important that the design of cooling forming device seems.
At present in chemical-fibres filaments spinning strand solidify coolingly, generally adopt lateral blowing cooling.Japan TMT, German Barmag have released the fine count fiber outer shroud blast-cold radiator cooler with international most advanced level, make with the energy consumption of economizing most, to reach best cooling effect from the spun silk of spinnerets.Owing to drying, area and wind supply quantity are only 1/5 of lateral blowing mode, greatly conserve energy.Because its blowing direction is circumferentially rather than a row, filament spinning component can doublely be arranged, and makes spinning station apart from reducing, and can rely on the coiling distance of positions spinning equipment of arranging, and is convenient to module management, saves factory building, equipment and public work investment, and fiber quality improves greatly.Outer-ring ventilation structure spins fine denier filaments more than 288 holes on the spinnerets of external diameter 85 mm, can spin the porous superfine denier fiber of high-quality filament number 0. 3 dpf.Guarantee that monofilament has uniform fiber number, degree of crystallinity and the degree of orientation, should guarantee that every monofilament has identical cooling condition.The lateral blowing form that tradition is used, because its cold wind is to blow to several bundle fibers away from outlet air surface on the net from very large-area wind, has wasted a lot of energy.Because of cold wind, from the nearly wind net of tow, blow to wind net far away place through tow, near air outlet, intensity of cooling is higher than away from air outlet place, and same cross section tow cooling condition is different.During the more porous yarn of the fiber that especially spinning polymeric heat is higher or radical, tow dissipation heat is very large, and nearly wind net is widely different with wind net far away place wind-warm syndrome, causes cooling the differing greatly of the every rhizoid in same cross section, the lack of homogeneity of as-spun fibre quality.
