Definitions

  • the present invention relates to the field of manufacturing a veil fibrous by air. More specifically, it relates to a process for forming a fibrous veil by dispersion and projection of fibers individualized, by means of an air flow, on a training surface and transporting the veil, the fibers having also been previously carded. The invention also relates to an installation for setting implementing this process.
  • airlay a technique of forming a fibrous veil, by air, which is commonly known as "airlay” technique .
  • This technique is characterized by the dispersion and projection of individual fibers, by means of an air flow, on a surface which is breathable and which allows the formation and transport of the fibrous web.
  • the individualized fibers undergo during their course in the air flow a random dispersion, which is commonly called “random" effect , and which contributes to obtaining a better isotropy of the mechanical properties of the fibrous veil.
  • the degree processing of fibers plays a major role on the homogeneity of the veil obtained.
  • This carding operation is generally carried out by means of a carding system comprising at least one cylinder carding, which is equipped on its periphery with combing means having for function of individualizing and orienting each other substantially in parallel to the others the fibers situated on the periphery of the carding cylinder.
  • these combing means can so usual be constituted by a worker roller associated with a roller stripper, or more often by several successive pairs of these two types of rollers;
  • These combing means can also be present in the form of a fixed fairing comprising a plurality of carding points, and commonly called carding plate.
  • carding plate At the end of combing means arranged at the periphery of the carding cylinder, obtains fibers which are plated on the surface of the carding cylinder by being individualized and oriented substantially parallel to each other to others in the longitudinal direction, corresponding to the direction of progression of matter.
  • the fibers are detached from the carding cylinder both under the effect of the air flow and under the effect of centrifugal force, knowing that to achieve the function carding machine, the last carding cylinder rotates at high speed high.
  • the air flow therefore has a double function: it helps detachment fibers from the surface of the carding cylinder; he directs the fibers, by randomly redirecting to a distant collecting surface breathable, for the formation and transport of the fibrous veil.
  • the dispersion of the fibers is further improved by the presence of an additional rotary cylinder (referenced 20 on the figures from application W096 / 06964) driven at high speed in the direction reverse of the last carding cylinder (referenced 8 in the figures of the request W096 / 06964), and placed on the path of the fibers in the flow of air.
  • the dispersing cylinder (reference 50) directly picks up the fibers at the periphery of the carding cylinder (referenced 40).
  • a transfer cylinder referenced 48
  • Communicaticator This cylinder has the simple function of taking up the fibers at the periphery of the last carding cylinder, and of transferring them as they are to the dispersing cylinder, without subjecting them to any transformation, and in particular without modifying their parallel orientation.
  • the first and second processes mentioned above are interesting in what they allow to obtain a satisfactory degree of working fibers, by a judicious adjustment, and perfectly mastered to date, of the action of the carding organs.
  • we find in practice that it is not enough to obtain a high rate of working of the fibers alone to obtain a homogeneous fibrous veil, and that ultimately the predominant factor affecting the quality of the fibrous veil lies in the random dispersion of the fibers by the "airlay" air flow on the surface of training and transport of the veil.
  • the parameters affecting this random dispersion are numerous and poorly controlled to date.
  • the first method has the disadvantage additional to require a very powerful "airlay” air flow to allow the spotting of fibers, which in practice are very strongly linked to the last carding cylinder.
  • the implementation of an air flow powerful causes air turbulence, which is difficult to to master, and which ultimately harm the homogeneity of the fibrous veil obtained, in particular by creating preferential groupings of fibers in the form of packages.
  • the air flow "airlay" does not function to detach the fibers from the periphery of a cylinder, and in this case the dispersing cylinder, and it can therefore advantageously be lower compared to the first process cited above.
  • the counterpart is the obligation to train a cylinder at very high speed (dispersing cylinder), which from an energy point of view is expensive, and is more delicate from a mechanical point of view, in particular due to the vibrational phenomena that can be generated on the cylinder.
  • this second method recommended in the application for International patent W097 / 20976 also has a drawback additional, which is linked to the choice of the peripheral lining of the dispersing cylinder.
  • the peripheral lining of the cylinder disperser must meet two contradictory constraints. She must on the one hand be aggressive enough to allow a recovery effective fibers at the periphery of the upstream cylinder (carding cylinder in the first variant, or "communicating" cylinder in the second variant), and thereby avoid damaging engorgement of this upstream cylinder, while being on the other hand not very aggressive to allow the fibers to be ejected under centrifugal force, and to avoid retention of fibers at the periphery of the dispersing cylinder. So we are forced to choose for the teeth of the lining of the dispersing cylinder an opening angle and a density of teeth which allow to obtain a compromise between these two contradictory constraints. This choice for the the dispersing cylinder lining is therefore very delicate and furthermore limit.
  • the present invention provides a new training process a fibrous veil, which is similar to the first and second processes aforementioned in that it combines an "airlay” technique of forming a fibrous veil to an upstream preparation of the fibers by carding, but which has the advantage over these two known methods of rendering the random dispersion of the fibers under the action of the "airlay” air flow less preponderant for obtaining a homogeneous fibrous veil.
  • the process of the invention is known in particular by one or the other of the aforementioned publications in that a fibrous veil is formed on a training and transport surface, dispersing and projecting on this surface individualized fibers by means of an air flow, and in that the fibers are subjected to a carding operation beforehand when they are introduced into the air flow.
  • one acts on the flow of fibers by means of one or more systems regulators to make this fiber flow more regular.
  • the fibers that come from the cylinder last carding cylinder are very strongly individualized and oriented substantially parallel to each other to others, because of the carding action they underwent; they form what is commonly called a "parallel" veil, which presents very weak cohesion in the transverse direction.
  • this carding action ultimately results in the production of a very irregular and non-homogeneous fiber web, even the flow material at the entrance of the card is constant.
  • the fibers being carded are strongly stretched, which causes the appearance of "holes” in the parallel veil from the carding, and on the other hand by the fact that the fibers have a time of more or less important course in the carding system, which mainly depends on their length; the shortest fibers are carded faster, while longer fibers have tendency compared to being retained longer in carding organs.
  • the rate of introduction of the fibers into the "airlay" air flow is completely irregular, which may explain, according to the applicant the preponderance of the action of random dispersion of the fibers by the flux airlay air to obtain a homogeneous fibrous veil.
  • the dispersion is advantageously made randomness of the fibers by the less preponderant "airlay” air flow for obtaining a homogeneous fibrous veil.
  • it is also advantageously possible to act on the homogeneity and thereby the isotropy of the "airlay" fibrous veil obtained on the formation surface and transport, by acting directly on the flow of the veil fibers parallel from carding, which is easier.
  • a carding system which is intended to be supplied of fibrous material, and which includes a carding cylinder at the outlet equipped on its periphery with means having the function of individualizing and orient the fibers substantially parallel to each other located on the periphery of the carding cylinder, and on the other hand for to make the flow of fibers from the carding cylinder more regular
  • we implements at least one first comb cylinder which is arranged to the periphery of the carding cylinder, which is intended to be driven in rotation with a circumferential speed strictly lower than that of the carding cylinder and in a direction of rotation opposite to that of the carding cylinder, and which is coated on its periphery with a lining the teeth or points of which point backwards, that is to say the opposite of its direction of rotation.
  • the comb cylinder acts as a regulating barrier to the fibers coming from the carding cylinder, by ensuring the recovery of only part of the fibers at the periphery of the carding cylinder, and regulating the flow of fibers.
  • the speed of rotation of this combing cylinder will be fixed according to the flow of fibers desired output from this cylinder.
  • the production line for a fibrous web of FIG. 1 includes a traditional loader-weigher 1 which feeds, via a conveyor 2, an installation 3 which is carried out in accordance with the invention and which makes it possible to form at the outlet a fibrous veil V, by ventilation using the "airlay" technique.
  • the card 3 comprises a card entry constituted by a trough 4 a , a food roller 4 b and a breaker cylinder 4 c .
  • the breaker cylinder 4 c supplies a first rotary carding cylinder 4 d , which is commonly known as the front end, and the surface of which is usually coated with a card lining or any other equivalent means enabling it to take up the fibers. from the periphery of the breaker cylinder 4 c .
  • the carding cylinder 4 d is further provided on its periphery with combing means making it possible to work the fibers taken from the card lining of this cylinder, so as to individualize and parallelize them.
  • these combing means consist of several successive pairs of a stripper roller 4 e and a worker roller 4 f . Downstream of these combing means, the fibers are taken from the periphery of the first carding cylinder 4 d and transferred in the state to a second rotary carding cylinder 4 h , by a transfer cylinder 4 g , also called a communicator.
  • the second carding cylinder also commonly called “large drum” or “main drum” is also coated with a carding lining or the like allowing it to take up the fibers at the periphery of the 4 g communicator, and is provided on its periphery with combing means (4 e , 4 f ) identical to those equipping the first carding cylinder 4 d .
  • the invention is not limited to a method or an installation using a card having the particular configuration of card 4 which has just been described with reference to FIG. 1.
  • a longer card implementing at least three successive carding cylinders, or on the contrary a shorter card implementing a single carding cylinder.
  • the rollers 4 e and 4 f could be arranged by being juxtaposed one behind the other in an alternating manner, according to a configuration commonly called "Garnett".
  • the cleaning and working rollers (4 e , 4 f ) at the periphery of each carding cylinder could also be replaced by any means of different structure, but fulfilling the same function, that is to say having the function, in association with the carding cylinder, to individualize and parallelize the fibers on the periphery of the carding cylinder.
  • these rollers could be replaced by static plates, commonly called “carding plates”, mounted on the periphery of the carding cylinder and comprising a plurality of carding points in the form, for example, of grooves or grooves.
  • the invention therefore applies to any process and any installation for forming a fibrous web by air, generally using at least one rotary carding cylinder equipped on its periphery. means having the function of individualizing and orienting substantially parallel to one another the fibers on the periphery of the carding cylinder.
  • each regulating system 5 is constituted by two successive cylinders 5 a and 5 b .

If one refers to Figure 3, the cylinder 6 is provided on its periphery with a covering whose tips 6a or teeth are directed forwardly with an angle of opening less than 90 ° C.
  • the means 8 for forming the “airlay” air flow mainly comprise a fan 9, the outlet of which is connected to a blowing channel 10, oriented substantially transversely to the forming and transport surface 7 has fibrous web V.
  • this blowing channel 10 consists of an upper portion 10 a whose section is slightly decreasing, and which extends from the outlet of the fan 9 to the periphery of the outlet cylinder 6 , and a lower portion 10 b which extends the upper portion 10 a from the periphery of the outlet cylinder 6.

  • a very light fibrous veil is obtained, which is commonly called “parallel veil", and the fibers of which are very highly individualized and oriented substantially parallel to each other in the machine direction, that is to say along the circumference of the carding cylinder 4 h .
  • This veil has very low mechanical strength in the transverse direction and is in practice pressed against the periphery of the carding cylinder 4 h , while being positioned in the bottom of the peripheral lining of this cylinder (FIG. 3).
  • the constituent fibers of the parallel web disposed at the periphery of the second carding cylinder 4 h undergo the following treatments.
  • the first cylinder 5 a of the upper regulating system 5 takes up only part of these fibers, and redirects them by breaking their parallelism.
  • This first cylinder 5 a is the main regulating member, which essentially acts on the flow of fibers so as to make this flow of fibers more regular.
  • the reoriented veil from this first cylinder is therefore more homogeneous than the parallel veil from the periphery of the 4 h carding cylinder.
  • the fibers of the condensed web on the periphery of the outlet cylinder 6 are detached from this cylinder, are dispersed randomly in the channel blower 10, and are individually projected on the surface 7a of the conveyor being divided into a zone 12 for forming the fibrous web V, that if one refers to Figure 1 extends over a distance d in the direction advancement of the conveyor belt.
  • a fibrous web is obtained V "airlay" whose fibers have been reoriented in the three directions, that is to say in the longitudinal and transverse directions of the surface 7a of the conveyor, and in the direction perpendicular to the plane of this surface 7 a (thickness of the web V).
  • This veil has improved homogeneity and isotropy compared to the parallel veil from the second 4 h carding cylinder.
  • the density and the thickness of the fibrous web V will depend on the linear speed of the surface 7 a , that is to say on the linear speed of the conveyor 7.
  • the stain removal of the fibers from the periphery of the outlet cylinder 6 is obtained under the combined effects of the "airlay” air flow which comes into contact with the periphery of this cylinder and centrifugal force imparted to the fibers due to the rotation of the outlet cylinder 6.
  • the air flow "airlay” is created relative to the outlet cylinder 6 so that it enters the lining of this cylinder, so as to obtain the maximum efficiency for stain removal of the fibers.
  • the airflow "airlay” is oriented in a direction substantially tangential to the periphery of the outlet cylinder 6, and the teeth or spikes 6a of the liner of this cylinder outlet 6 are oriented in the direction of this airflow "airlay”.
  • the air flow speeds "airlay” in the blowing channel 10, at the outlet cylinder 6, are preferably greater than the circumferential speed of the outlet cylinder 6, so that the air flow best assist in stain removal of fibers. It is up to the person skilled in the art to provide the air flow required for the fan 9, as a function of the circumferential speed of the cylinder 6, as well as the volume and the section of the blowing channel 10, in order to obtain the speeds d air required.
  • the line in FIG. 1 was intended to produce a fibrous web from polyester fibers, having a titration of 1.7 dtex and an average length about 38mm.

  • the installation of the invention which has just been described with reference to Figures 1 and 3 has several advantages.
  • the main advantage derives from the implementation, between the outlet of the card 4 and the "airlay" air flow, of at least one regulating system 5 advantageously making it possible to supply the blowing channel 10 with a flow of fibers which on the one hand is more regular compared to the flow of fibers at the output of carding machine 4, and which on the other hand can be adjusted mainly by adjusting the rotational speeds of the combing rollers 5 has regulating systems 5.
  • the effect of random dispersion of the fibers in the “airlay” air flow continues to play a role in the homogeneity and the isotropy of the fibrous veil V obtained;
  • this effect is less preponderant than in the previous solutions, and it becomes possible to act more easily on the homogeneity and the isotropy of the veil V, and thereby more easily improve the homogeneity and the isotropy of this veil, by judiciously regulating the flow of fibers by means of regulating systems.
  • Another advantage of the invention lies in the greater ease of detaching the condensed web from the periphery of the cylinder outlet 6, compared to the solutions of the prior art. So when the "airlay" air flow assists in spotting fibers from the periphery of the outlet cylinder 6, it is possible to implement an air flow less powerful, compared for example to the solution of publications EP-A-0.093.585 (CHICOPEE) and W096 / 06964 (HERGETH HOLLINGSWORTH GMBH); when the stain removal of the fibers from the periphery of the outlet cylinder is obtained exclusively under the effect of centrifugal force, it is advantageously possible to obtain this stain removal of fibers with a lower circumferential speed to the output cylinder, compared for example to the speed circumferential which is necessary for the dispersing cylinder of the solution described in publication W097 / 20976 (E.l. DUPONT DE NEMOURS AND COMPANY).
  • An additional advantage of the solution of the invention compared for example to the solution recommended in publication W097 / 20976 (El DUPONT DE NEMOURS AND COMPANY) lies in the possibility of opting for a slightly aggressive packing for the outlet cylinder ( lower density of the teeth or points of the lining and greater opening angle of these teeth or points relative to the tangent of the cylinder), and in particular less aggressive than the lining which must be used for the dispersing cylinder of the publication W097 / 20976.
  • the production line for a fibrous web, by air, of FIG. 2 differs from that of FIG. 1, only by the direction of rotation of the second cylinder 5 b of each regulating system 5. This direction of rotation is reversed relative to the direction of rotation of the output cylinder 6. As a result, the teeth or points of each second cylinder 5 b are no longer oriented towards the rear as in the variant of FIG. 1, but are oriented towards the front . For this reason, in order to allow fibers to be taken up by the outlet cylinder 6, it is necessary in this variant that the circumferential speed of the outlet cylinder 6 be strictly greater than that of the second cylinder 5b .
  • the variant of FIG. 2 has all the advantages of the variant of FIG. 1, and also has the additional advantage of avoiding a reversal of the condensed veil during the passage of this veil between the second cylinder 5b and the cylinder of exit 6.
  • the invention is not limited to the particular variant embodiments of FIGS. 1 and 2. It is notably possible to envisage using more than two regulating systems 5 in parallel, and distributed over the periphery of the carding cylinder 4 h ; the structure of a regulating system is not limited to the implementation of two successive cylinders 5 a and 5 b ; in particular, it will be possible to use a regulating system consisting solely of one or more combing cylinders 5 a and not comprising a condensing cylinder; in general, we can use instead of the two cylinders 5 a and 5 b , any structure ensuring the same function, that is to say ensuring the recovery of only part of the fibers at the periphery of the carding cylinder 4 h , and making it possible to improve the regularity of the flow of fibers, prior to their dispersion by the "airlay" air flow.
