Definitions
- the invention relates to an improvement made to installations allowing the production of nonwoven fibrous webs whose cohesion is obtained by intermingling of fibers in the thickness of said web thanks to the action of jets of fluid, and more particularly of jets of water, of small diameter and having a high speed.
- US-A-3,906,130 relates to a perforated nonwoven.
- the oscillations are intended to promote the transverse deposition of the filaments and the formation of loops of filaments.
- FIG. 5 of this document also shows that the members delivering the water jets (item 36) intended for consolidating the layer of filaments are placed on a non-oscillating conveyor 15 independent of the oscillating conveyor 1 on which the filaments are deposited .
- the inventor specifies that the equipment 33, 34 and 35 arranged above the conveyor 1 are nozzles for impregnating a solution of caustic soda for a "scouring" treatment.
- This treatment with caustic soda can in no case be compared to a consolidation by water jets, in other words to a hydraulic entanglement of the fibers. It is usually carried out at pressures not exceeding 5 bars and by flat or conical jets.
- US-A-4 252 590 relates to a process for forming a sheet of continuous filaments whose transverse properties are improved by a transverse displacement of the support 3.
- US-A-3 833 438 describes a particular so-called "wet" spinning system in which the extruded and coagulated filaments are received on a conveyor animated with a transverse oscillation movement.
- references 29 and 30 correspond to impregnation systems for acidic or basic chemical treatments as is done on sheets of filaments after spinning them.
- This document makes no mention of the use of water jets to achieve hydraulic entanglement of the filaments, and even less of any disappearance of the lines left by the water jets in the layer of filaments.
- the present invention relates to an installation for producing nonwoven fibrous webs making it possible to entangle the fibers of a nonwoven web by means of water jets without having visible marks and imprints of the water jets in and on the surface of the nonwoven plies and without, however, requiring the setting in motion of hydraulic equipment.
- the subject of the invention is an installation for producing nonwoven fibrous webs comprising a conveyor on a strand from which a nonwoven fibrous web passes under an injector which projects jets of fluid onto the web and preferably above a box. communicating with a source of depression.
- a means is provided for giving the conveyor an oscillating movement at least partially transverse to the direction of movement of the strand.
- the injector oscillation techniques like that of the conveyor, have the disadvantage of setting very large masses into motion.
- the injector weighs between 1000 and 1500 kg. Devices for moving such large masses are extremely expensive.
- the installation is such that the fibrous web passes between the injector and a box communicating with a source of vacuum and the means is arranged so as to give the movement of oscillation in the box.
- the conveyor applies to it and follows its movement.
- a very simple way has thus been found of giving the conveyor and therefore the fibrous web which is pressed thereon by the effect of the vacuum an oscillating movement while leaving the injector fixed. It is much easier to give an oscillation movement to an essentially empty and therefore light-weight box than to the injector or even directly to the conveyor.
- the oscillation movement can be purely perpendicular to the direction of movement of the strand but it can also be inclined with respect to this direction, the main thing being that there is a component of the oscillation movement which is perpendicular to the direction of displacement of the strand and the direction of the jets which is most often vertical.
- the frequency in Hz represents from 2 to 20 times the speed of the sheet expressed in m / min, this speed of the sheet being preferably between 5 and 50 m / min.
- the number of jets is between 12 and 77 jets / cm of the part of the sheet receiving the jet.
- the fluid projected by the injector is a liquid and in particular water.
- the jets project fluids at a pressure which is preferably between 20 and 600 bars.
- the jets are cylindrical and come from nozzles with a diameter of 80 to 170 microns to give jets of the same shape and diameter.
- the box is mounted suspended on elastic means, in particular on springs or on silent blocks.
- the conveyor is usually a metal or plastic endless conveyor and the fluid can pass through the conveyor.
- injectors are associated with a single box.
- a single oscillating box is below several injectors, in particular two or three injectors, makes it possible not to have two boxes animated by their own movement, which could create harmful harmonics.
- FIG. 1 is a schematic perspective view of an installation according to the invention.
- FIG. 2 illustrates a means intended to give the box an oscillating movement.
- FIG. 3 illustrates a variant.
- two banks 4 of injectors are provided providing water jets under 300 bars with a diameter of 120 ⁇ . These jets are directed vertically on the ply 3 and in the part above the injectors 4 there are fifty jets per centimeter of the ply.
- Below the strand 3, and facing the injector 4 is mounted on a spring 5 a box 6 communicating with a source 7 of vacuum.
- the box is animated, by means shown in Figure 2, an oscillating movement symbolized by the double arrow F horizontal and perpendicular to the direction of movement of the strand 3.
- the amplitude of the oscillations is 4 mm.
- the box performs fifty oscillations per second.
- the oscillation movement is obtained by a rod 8 and crank 9 device driven in rotation by a motor which is not shown.
- a rod 8 and crank 9 device driven in rotation by a motor which is not shown.
- other means could be used to give the box an oscillating movement, for example a rotary vibrator, a linear piston vibrator or an eccentric mechanism.
- the oscillation movement is communicated to a roller 10 for returning the strand 3 of the conveyor 1 by a piston vibrator.
