Description

Manufacturing is by the polymer particularly artificial long tow that forms of polyamide, polyester or polypropylene or the method and apparatus of artificial fibre
The present invention relates to a kind of manufacturing by the polymer particularly artificial long tow that forms of polyamide, polyester or polypropylene or the method for artificial fibre, wherein in the melt spinning process of micro filament, at least be cooled to setting temperature in the cooling zone of micro filament after spinning head with the given speed drawing-off, then be heated on the freezing point temperature in the thermal treatment zone, so that stretch, in order to improve frictional resistance and to produce required tensile stress, blow to micro filament simultaneously with a kind of gaseous medium.
Such method is known: the artificial filament who promptly passes the thermal treatment zone is laterally dashed by air draught and blows.This artificial filament is by 50 long filaments or claim monofilament to form, and wherein long filament or filament number can be 1.0 dtexs where necessary, and general provision is 3.0 dtexs.The above-mentioned thermal treatment zone is made of a proportional heating tube of length, and its length is 3 meters.The long filament of being extracted out by spinning head has been formed the artificial long tow that will be heated in order to stretching after cooling and be integrated bundle before entering heating tube.The result of bunchy has caused the mutual applying between the long filament like this, has caused uneven heat treated thus.This is disadvantageous for various reasons.At first, drawing process will be affected, and be almost impossible because at this moment long filament is heated to more than the freezing point equably, be almost impossible so artificial long tow's entire cross section evenly is heated to more than the freezing point temperature.Artificial long tow's state relation is to the raising of frictional resistance, so that produce the required tensile stress that stretches.Here only dash in cross-sectional direction and blow this artificial long tow, this operation will be difficult.General draw rate or winding speed can not improve arbitrarily in above-mentioned known method, only are 3500 meters/minute.This is not only unfavorable to productivity ratio, and has the percentage elongation of proportional increase with the artificial long tow that this known method is produced, if the words of its filament fiber number＞1.0 dtexs.This artificial long tow need carry out post processing just can be used for weaving processing.At last, because water back or heating path are longer, this artificial long tow's manufacturing equipment is built quite tall and big.
Therefore the purpose of this invention is to provide a kind of method, produce full stretching artificial long tow or artificial fibre (FOY=fully oriented filament) by this method with high production rate, these artificial long tows or artificial fibre do not need post processing just can be directly used in textile industry, and can be processed into meticulous especially, submissive or as the product of real silk.In addition, the present invention also provide a kind of corresponding, build very short and small equipment.
The method that provides according to an aspect of of the present present invention has solved above-mentioned task, i.e. the micro filament of filament fiber number＜1.0 dtexs boundling orientation not, and just they pass the thermal treatment zone in parallel to each other, and are dashed along countercurrent direction by gaseous medium such as air and to blow.Adopting the filament fiber number in preferred version is the micro filament of 0.4 to 0.8 dtex.Technical scheme of the present invention builds on the following understanding basis: dash with adverse current and blow micro filament and can improve frictional resistance, and can form without difficulty and extend required tensile stress fully.Contrary air-flow means higher air drag, so the raising of draft speed increases the tension force of long filament.Leng Que micro filament was heated to its freezing point temperature again when above before reeling in the thermal treatment zone in the ban, and good stretching causes that the tension force of endless tow increases.According to technical scheme of the present invention, micro filament passes from the thermal treatment zone under the state of bunchy not, thereby the entire cross section of micro filament is all evenly heated.This even heating has promoted the full orientation or the stretching of micro filament, and then has also promoted corresponding artificial long tow's full orientation or stretching.Above-mentioned artificial long tow or all show low especially percentage elongation by its artificial fibre made or the staple fibre that is used for (weak point) silvalin.Because the fiber number of long filament is less, they need not carry out other post processings, just can use.Like this, with the inventive method make endless tow can make meticulous, submissive, as the product of real silk.The method according to this invention, the stretching of micro filament is only carried out in air drag and under the temperature of the thermal treatment zone.Therefore, as far as possible little fiber number particularly filament number is particularly advantageous, because like this can be comparatively fast and control easily or adjust the tension force and the temperature of long filament.In addition, still can produce with higher draft speed although shortened thermal treatment zone the present invention, thus the productivity ratio that improves.
The further inner characteristic of the present invention now is described below.The present invention stipulates like this: in contrary air-flow the temperature of heating micro filament between 150 ℃ to 250 ℃, preferred 220 ℃; The draft speed that these micro filaments pass the thermal treatment zone 3500 meters/assign between 8000 meters/minute preferred 4500 meters/assign to 5500 meters/minute.The micro filament of heating is gathered bunchy by rights after passing the thermal treatment zone and before reeling, thereby carries out handling especially uniformly and stretching in the thermal treatment zone.
Object of the present invention also relates to a kind of equipment, and this equipment is owing to simple and compact for structurely be very suitable for implementing said method.This equipment has a spinning head, a spinning shaft, a heating path, a pretreatment unit, a godet roller and a coiler device at least, it is characterized in that: described heating path has the air-blast device of the contrary air-flow of a generation in discharge one side, air-blast nozzle for example, this heating path is positioned at 0.8 meter to 1.2 meters, spinning head below, is provided with along the filament drawing direction.This heating path length is 1 meter to 1.5 meters, preferred 1.2 meters.Like this, compare with known equipment, the construction height of the thermal treatment zone is actual to have reduced 50%.In addition, micro filament and will change by the heating-up temperature in heating path and the change of counter-flow air quantity delivered by its artificial long tow's who produces degree of drawing.
