Technical field
The present invention relates to a kind of by claim 1 method that is used for handling the tow that is used to make synthetic staple as described in the preamble and a kind of by claim 9 equipment that is used for implementing this method as described in the preamble.
Background technology
By US6, the method and apparatus of 203,743 known a kind of these types.
In known method and equipment, the tow that is made of a large amount of synthetic filaments bars at first is conducted through the wetting apparatus of a soak bath form after extracting out from creel, so that it is wetting uniformly that all fibres bar is obtained, and during handling, obtain the reliable merging of single fiber thus.Here preferably adopt oil agent as liquid, this oil agent can be advanced tow reliably on the treating apparatus of fiberline.In addition, the liquid in the tow during drawing process, cause the monofilament bar each other good substantially, conduct heat and mobility uniformly.Only have enough water capacities and could produce tow with high stretching.Following wetting tow is stretched in the drawing zone between two draw roll devices.The tow that is stretched then is directed on a plurality of heated calenders, to finalize the design and drying.For with particularly reducing to minimum on the calender for the dry required energy of tow, before tow is about to enter calibrator, tow is imported a mangle device, tow is conducted through a roll gap that is formed by steel rider in this mangle device.Therefore tow can be extruded big quantity of fluid from tow before handling on the calender.Carry out the cooling of fiber and Texturized after the dry and typing at tow, so that then they are cut into staple fibre.
In known method and equipment, there is such shortcoming,, must under the situation of the high water capacity of tow, carries out promptly in the typing of tow with the adjustment of the processing, the particularly tow that carry out between stretching.Therefore the major part of energy that is used for regulating strand temperature is only required for the liquid that heat packs is contained in the tow.In addition, the minimizing of liquid one has existed on the position of higher fiber speed and has carried out in fiberline in the tow.Therefore have to take special measure, so that extract a large amount of at short notice liquid that occur from tow.In addition, be created in the problem that causes inhomogeneous liquid distribution on the tow width thus because in the mangle device vibration of mangle instrument and therefore the danger of roll gap inhomogeneities improved.
Summary of the invention
Therefore the objective of the invention is to improve such method and apparatus like this, make that the content liquid in the tow is complementary with the processing work step when handling tow.
Another object of the present invention is, reduces the liquid in the tow like this, makes that the residual liquid in tow evenly distributes on whole width.
This purpose realizes with having by the equipment of the described feature of claim 9 by the method that has by the described feature of claim 1.
The favourable improvement project of the present invention is limited by the feature and the feature combination of corresponding dependent claims.
In order to realize described purpose, the present invention takes a kind of brand-brand-new way, and it is considered to and can not realizes in speciality circles up to now, because such viewpoint prevails, promptly high strength ground must cause the damage of fiber to the tow mangle in drawing zone.But find that surprisingly have such zone in drawing zone, the tow mangle that is used to reduce liquid in the tow in this zone can not cause the damage of fiber.On the contrary, in drawing zone, can from tow, discharge big quantity of fluid.Here the hydraulic fluid of tow carries out on the whole width of tow like this in drawing zone, make in tow, obtain liquid tow handle equally distributed on the width,＜10% part by weight.Equipment of the present invention for this reason has the mangle instrument of bending rigidity, described mangle instrument on whole width equably, tow is carried out mangle with the pressure of predesignating basically, to extrude liquid.The original drawing process of tow is not influenced by this, can have quite high part by weight＞20% scope in for the required content liquid that stretches thereby make in tow.The advantage that the present invention is special is, tow can have in the zone of lower gait of march one imports the mangle device.Can avoid vibration and inhomogeneities thus.In addition, guaranteed to guide reliably ribbon to pass the mangle instrument and do not carry any single fiber secretly.In addition, increased action time when the tow mangle, made and from tow, to discharge big quantity of fluid by low speed.
In order to obtain the strong and big stretching of tow monofilament bar, the preferred such improvement project of the present invention that adopts, tow is defining in the inlet region of draw roll device of drawing zone by mangle in this scheme, and wherein tow is heated to the draft temperature that is used at fibrous material internal trigger drawing point by heated liquid in drawing zone.For tow is heated to draft temperature, tow preferably is conducted through one to have the steam channel of high-temperature steam or regulates the stretching bath of temperature by one.The mangle device is arranged in the inlet of the second draw roll device, thereby makes the monofilament bar that enters the mangle device finish its main stretching.
If the mangle instrument is made of the steel rider that has a roll gap between self, then the mangle for tow proves particularly advantageous.Different according to content liquid and tow performance, steel rider presses mutually with the linear load in 30N/mm to 100N/mm scope.Guarantee thus, even also can realize the part by weight of liquid＜10% when big quantity of fluid is arranged in tow.
Here tow is compressed at least 70% of its original tow thickness in roll gap.This feasible particularly can realization for drawing process can be at the high content liquid more than 40%.In a kind of favourable improvement project of the present invention, imagine, tow on first draw roll that is wound into the second draw roll device time by a hold-down roller mangle that is close on this draw roll.The long filament flow process that is intended for stretching that therefore can keep tow.In addition, because do not need independent drive unit to drive steel rider, the mangle device is reduced to minimum aspect cost of equipment.By driven draw roll, hold-down roller can advantageously only drive by rubbing.
Also have such possibility in principle, promptly tow in a plurality of level by mangle, so that reach the content liquid of hope.A plurality of positions are set in the draw roll device for this reason, on these positions, tow are carried out mangle.Like this, other draw roll also can combine with hold-down roller except that the draw roll that is arranged on the porch.Equally also can be in the draw roll device built-in two independent steel riders.
In order to handle the synthetic filaments bar in the tow, preferably adopt the such improvement project of the inventive method, wherein tow heats by the heated draw roll of the second draw roll device after expression of fluid.Because the little content liquid in tow makes the energy that provides by draw roll can directly be used for heating tow.The loss of energy that only is used for heating liquid reduces to minimum.
For the typing and the shrink process of tow, the processing by calender proves particularly advantageous.Tow by a plurality of calender guiding, wherein can reduce to minimum for the dry required energy of tow equally owing to the little content liquid of tow after stretching for this reason.
Method of the present invention on the whole is rendered as the option of advantageous particularly and tow processing reliably, wherein compares with conventional method and can realize significant energy-efficient.For example the energy by the tow typing before entering the second draw roll device of tow mangle can reduce 20%.Here when being used for the heat treatment of tow typing, produce another particularly advantageous effect.Because the little content liquid in tow reaches higher fibre strength, this fibre strength is compared with conventional method can improve 6% to 10%.
In equipment of the present invention, the mangle instrument of particularly making steel rider can be built in the drawing zone with simple methods.Here the such improvement project of present device proves particularly advantageous, and wherein in the steel rider constitutes by driven draw roll of the second draw roll device, and second steel rider constitutes by the hold-down roller that is equipped on the draw roll periphery.Therefore, guaranteed that the mangle device is built in the drawing zone fully, and do not needed extra director element and steering component to guide tow.
Hold-down roller is preferably designed to and has the roller that nothing one-sided or the bilateral supporting drives for this reason.
In order to produce constant and uniform roll gap for the bigger and more firm draw roll of diameter, hold-down roller is preferably made the box hat with deflection-compensated, thereby makes the roll gap between hold-down roller and the draw roll equally big on the whole width of tow.Here the box hat of the deflection-compensated of hold-down roller is made like this, makes roll gap have＜the roll gap difference in height of 0.05mm.Can be implemented in very uniform amount of liquid on the tow width thus.
The extruding force that tow is compressed in required being used between steel rider advantageously produces by the power generating means, and this power generating means produces one at least at the linear load in 30N/mm to 100N/mm scope uniformly on the steel rider width.
For in a plurality of level to the tow mangle, equipment of the present invention can be made like this, it is right promptly on a plurality of positions that are provided with in succession a plurality of rollers to be set respectively.Roller is to also being formed by a plurality of hold-down rollers in this respect, and described a plurality of hold-down rollers set respectively to one in the draw roll of the second draw roll device.
No matter the right structure of roller how, hold-down roller or two steel riders are done to such an extent that have surfaces hardened, and described surface preferably has the surface texture of a sweet orange shape.Avoid thus that fiber adheres to and is bonded on the roller periphery when ribbon comes out from roll gap.Therefore ribbon is advantageously thrown off from steel roller faces, thereby does not form package.
Method and apparatus of the present invention preferably is used for handling the tow of being made by polyester in a plurality of levels before cutting into staple fibre.Here the monofilament bar of tow is preferably extracted out from ready prepd tube, and this tube fills up by the melt-spinning of monofilament bar in spinning process in advance.But this method is not limited only to this two-stage approach that is used for making staple fibre in principle.Also exist in the possibility of making the monofilament bar in the simple process.
In order to make polyester fiber have high as far as possible intensity after stretching, tow is preferred by a plurality of heated calender guiding after stretching.Because lower water capacity in the tow can be carried out strong heat treatment to fibrous material, wherein the required energy of fibrous material dries can be saved in calender basically.
