Definitions
- the invention relates to a method for producing cellulosic continuous moldings, such as filaments, staple fibers, membranes and foils, in which an extrusion solution containing water, cellulose and tertiary amine oxide is extruded to form at least one continuous molded body and then the continuous molded body is stretched, then the continuous molded body is taken up on a conveyor and is withdrawn from the conveyor by an extractor.
- an extrusion solution containing water, cellulose and tertiary amine oxide is extruded to form at least one continuous molded body and then the continuous molded body is stretched, then the continuous molded body is taken up on a conveyor and is withdrawn from the conveyor by an extractor.
- the invention further relates to a device for producing cellulosic molded articles, such as filaments, staple fibers, membranes and foils, from an extrusion solution of cellulose, water and tertiary amine oxide, with at least one extrusion nozzle opening through which the extrusion solution flows and downstream of which the extrusion solution is extruded into an endless molded body, and with a withdrawal mechanism, by means of which a tensile stress can be applied to the continuous body and the continuous molded body can be removed from the device.
- a device for producing cellulosic molded articles such as filaments, staple fibers, membranes and foils
- the dimensions of the extruded continuous moldings are set after the coagulation and stabilization by applying tensile stress.
- the tensile stress is generated by the take-off mechanism, which picks up the continuous molded body, pulls it off and feeds it to further process steps.
- a composite of a plurality of continuous molded articles in the form of spun threads is combined and drawn off via a deflection roller after it has emerged from a spinneret surface.
- the deflection roller is arranged in a precipitation bath.
- the threads Due to the strong deflection of the continuous moldings on the deflection roller in the coagulation bath, the threads are subjected to high mechanical loads. This leads to impairments in the fiber quality, so that the method and the device of WO 93/19230 produce fibers which tend to become brittle, fibrillate and break the filament. Due to the deflection within the coagulation bath, the device and the method of WO 93/19230 set limits with regard to the speed of the spinning thread in the coagulation bath due to the viscosity of the coagulation bath.
- the fibers obtained by the method and the device of WO 96/30566 have poor textile properties.
- the tendency to fibrillation, the loop strength and the curling behavior leave something to be desired.
- viscose spun filaments are drawn off in the form of a continuous cable by means of rollers, deflected over several rollers and then passed onto a belt conveyor to form a spunbonded nonwoven. This process consciously strives to form a tissue.
- This system is not suitable for the production of staple fibers because of the tangles that form and because of the entanglement of the filaments.
- This method also produces fibers that have only moderately good fiber properties.
- the invention is therefore based on the object of creating a method and a device by means of which the textile properties of continuous moldings such as staple fibers and filaments can be improved.
- the method and the device also have the task based on the fact that the tendency of the fibers to fibrillate is reduced and the loop strength is increased.
- this aim is achieved for the method mentioned at the outset in that the continuous molded body is received on a conveyor after shaping and is conveyed to the take-off unit on the conveyor essentially without tension.
- the object is achieved according to the invention in that a conveying device is provided between the extrusion die opening and the draw-off mechanism, by means of which the continuous molded body can be conveyed to the draw-off device essentially without tension.
- the continuous molded body is conveyed essentially free of tensile stress in an area in which it can solidify and stabilize or relax.
- the textile properties of the endio-shaped body improve considerably through such a method and device if no mechanically applied tensile stresses act on the continuous-form body in the critical area after shaping.
- the apparatus and method of the invention can be both, Filamentverbunden, membranes are used and development for the manufacture of staple fibers ⁇ for producing films.
- the continuous molding is a spinning thread and the extrusion die opening is a spinneret opening.
- Conveyors in the field of spinning technology which essentially convey tension-free.
- these conveyors are not suitable for improving the textile properties of the extrudates transported on them.
- DE 29 50 015 shows an oscillating conveyor which conveys a fiber cake through a washing machine.
- this vibrating apparatus is arranged behind an extraction unit 17 in the extrusion direction of the continuous molding.
- the continuous molded body is drawn off directly from the extrusion die under mechanically applied tensile stress. As explained above, this has a disadvantageous effect on the textile properties of the continuous molding.
- the textile properties of the continuous molded body can no longer be influenced.
- the vibratory conveyor described therein is only used to wash out the fibers.
- WO 98/07911 describes an apparatus and a method with which nonwovens are produced.
- the extruded filaments are drawn and comminuted by strong air currents immediately after exiting on an extrusion nozzle in the form of a spinneret. These short fibers then fall into a tangled position on a belt conveyor, on which they coagulate to form a fleece mat.
- the method and the device of WO 98/07911 are not comparable to the method and the device according to the invention, since no continuous moldings can be formed.
- the method and the device as described in WO 98/07911 are not suitable for the production of uniform fiber properties. This manifests itself in very strong fluctuations in titer and in uneven tensile and loop strength values. Due to the confusion of the individual filaments and the necessary transfer Staple fibers by cutting the continuous filaments cannot achieve uniform cutting lengths - the cutting length is widely scattered.
- the aim of the present invention is to improve the mechanical properties of each individual molded body.
- the continuous molded body is not comminuted during its transport to the take-off unit.
- the mechanical properties of the nonwoven mat of WO 98/007911 are essentially influenced by the type of tangle and not by the properties of the individual, shredded threads.
- a tension-free conveying of the endless molded body on the conveying device is particularly advantageously possible if, in a further embodiment of the method or the device, the endless shaped body is conveyed on the conveying device at a conveying speed that is lower than the extrusion speed of the endless shaped body.

- the continuous molded body can relax during the conveyance and, after the relaxation, can be picked up by a take-off mechanism and fed to a cutting machine.
- the continuous molded body can be drawn off by the take-off mechanism at a take-off speed which essentially corresponds to the extrusion speed of the continuous molded body.
- the conveying device thus forms a type of intermediate buffer zone in which the extruded continuous molded body is transported without tension.
- the high removal speed of the take-off unit ensures that the buffer area does not overflow and that the processing speed of the further processing steps behind the removal device corresponds to the extrusion speed.
- the endless molded body is conveyed on the conveying device by means of a reciprocating movement of the conveying device, preferably transversely to the conveying direction.
- the conveying device can be designed as a shaking, vibrating or vibrating conveyor. Due to the reciprocating movement of the conveyor device, it is possible in a further embodiment to use this movement necessary for conveying the endless molded body at the same time for a geometrically ordered placement of the endless molded body in the form of an endless molded body cake on the conveyor device: the endless molded body meets the moving conveyor device and is automatically placed in a wave-like or wide area due to the relative movement between the continuous molded body and the conveyor, so that the molded body can relax well.
