Description
[technical field]
The utility model relates to a kind of fiber melt spinning spinning pack, particularly a kind of spinning spinning pack that is used to contain the low boiling point solvent melt.
[background technology]
Melt to containing low boiling point solvent carries out spinning, and when melt got in the air by the spinning nozzle ejection, because solvent boiling point is low, volatilization easily was prone in tow, produce bubble in air, influences the tow quality.For preventing that melt from producing bubble in the tow when spinning nozzle is extruded; Prior art provides a kind of spinning spinning pack; The spinning nozzle of spray fiber tube is arranged in the cooling fluid in this spinning spinning pack, and the tow of spinning nozzle ejection directly cools off in cooling fluid, and melt temperature dropped to below the easy volatile solvent boiling point in short time; Thereby can reduce the volatilization of easy volatile solvent, reduce foamed phenomenon.But; In the prior art; Even the time that the tow of spinning nozzle ejection is cooled in cooling fluid below the volatile melt boiling point is very short, still to keep away and have the bubble that produces because of the easy volatile solvent volatilization on a small quantity in the tow that unavoidably makes, the tow that makes is second-rate.
[summary of the invention]
The utility model patent has proposed a kind of pressurization spinning spinning pack to above-mentioned deficiency of the prior art, utilizes this filament spinning component spinning, does not have the bubble that produces because of the easy volatile solvent volatilization in the tow that makes, and the tow quality is high.
For solving above technical problem, the utility model provides following technical scheme.
A kind of pressurization spinning spinning pack comprises assembly overcoat and spinnerets that places the assembly overcoat and spray fiber tube, and said spray fiber tube one end is connected with spinnerets, and the other end is the spinning nozzle that wire vent is used; This pressurization spinning spinning pack also comprises compressed air cell and the cooling bath that places the compressed air cell below; Said spinning nozzle places in the said compressed air cell; Said compressed air cell and cooling bath are equipped with opening.
Preferably, said spinnerets arranged outside has high temperature resistant heat insulation material.
Preferably, in the said cooling bath cooling fluid is housed.
Preferably, said cooling bath is connected with the circularly cooling device.
Preferably, said spinning spinning pack also comprises melt filtration net and porous plate; Said porous plate one side is connected with the melt filtration net, and opposite side is connected with spinnerets.
The spinning nozzle of the pressurization spinning spinning pack that the utility model provides places compressed air cell; The tow of spinning nozzle ejection is compressed the effect of air in compressed air cell; The elevation of boiling point of easy volatile solvent is to more than the ambient temperature; At this moment, easy volatile solvent is non-volatile, does not produce bubble in the tow.Simultaneously; The tow of spinning nozzle ejection is ejected to by spinning nozzle that temperature reduces gradually in the process that arrives the opening on the compressed air cell; When tow is flowed out by the opening on the compressed air cell; The temperature of tow has been reduced to below the easy volatile solvent boiling point, even at this moment tow is exposed in the air, also can not produce the phenomenon of foaming.In sum, pressurization spinning spinning pack provided by the invention spinning pack more of the prior art can better prevent that tow from bubbling, and does not have the bubble that produces because of the easy volatile solvent volatilization in the tow that makes, the tow quality better.
