Definitions

  • the present invention relates to the textile field, and more particularly the field of production of nonwovens by means of a card. Its main objects are a new card, the output has been perfected, as well as a new production process of a carded nonwoven.
  • the invention preferably finds, but does not exclusively, its application to high speed production (typically production speeds greater than or equal to 150 m / min), of carded nonwovens composed of fibers of the type Polypropylene, Polyethylene, cotton, viscose, etc ...
  • a card for the production of a nonwoven comprises of basically at least one rotary carding drum, again commonly known as the main drum or large drum, at the periphery of which are mounted carding organs.
  • the fibers transported to the periphery of the drum carding are individualized (fiber carding operation) by combined actions of the carding organs and the lining carding drum device.
  • these carding organs are composed by one or multiple successive carding groups, each carding group being composed of a roller commonly called “worker” associated with a “scrubber” roller, also called a “sweeper”.
  • these carding organs can be fixed and be in the form of a fixed fairing (again commonly called “carding plate”) comprising a plurality carding points fixed at the periphery of the carding drum.
  • a first known card output configuration allowing the production of a parallel nonwoven, implements, as cylinders for forming the non-woven veil, one or more successive combing cylinders.
  • a second known card output configuration allowing the production of a scrambled nonwoven, implements, in as cylinders for forming the nonwoven web, a cylinder commonly known as a "counter-drum” followed by a cylinder comber.
  • a third known card output configuration allowing the production of a condensed nonwoven, implements, in as cylinders for forming the nonwoven web, a cylinder comb, followed by at least one condensing cylinder; most of time the comb cylinder is followed by two condensing cylinders successive.
  • a fourth known card output configuration highlights work, by way of cylinders for forming the non-woven veil, a counter-drum cylinder followed by a painter cylinder and a cylinder condenser.
  • the drum carding plays a role in both the function of individualization fibers (carding of fibers by carding organs in cooperation with the carding drum), and in the formation of the nonwoven web at the end of the card by the sail forming cylinders, from the individualized fibers transported around the drum carding.
  • the speed of rotation of the carding drum is an adjustment parameter which conditions preponderant both the carding quality of the fibers at the periphery of the carding drum by the carding organs, and the properties mechanics of the nonwoven produced (isotropy, grammage, ).
  • obtaining the required quality of carding fibers requires adjusting the speed of rotation of the carding drum in a relatively narrow speed range, and from that carding drum speed adjustment, card designer deduces the speed settings of the sail forming cylinders, kind of obtaining a nonwoven with mechanical properties required (grammage, isotropy, ).
  • the card designer Since the speed setting range of the drum carding is narrow compared to the fiber carding function which must be provided by this drum, the card designer is in limited practice in its choice for the rotational speeds of the non-woven veil forming cylinders, and thereby in the adjustment of the production speed of the nonwoven at the card exit. In Besides, it is difficult to increase the production speed of the nonwoven at the end of the card, without damaging the mechanical properties of the web.
  • the present invention aims to propose a new carding structure which overcomes the aforementioned drawback, in that it offers greater flexibility in adjusting the speed of the cylinders formation of nonwoven.
  • Another object of the invention is to be able increase the production speed of the card, without damaging the mechanical properties of the nonwoven produced.
  • the card of the invention is known in that it comprises a carding drum, carding members mounted on the periphery of the carding drum and at least one carding outlet comprising at least minus a first cylinder for forming a nonwoven veil.
  • the card has an accumulator transfer cylinder between the drum carding and the first cylinder for forming a nonwoven web.
  • the accumulator transfer cylinder of the card of the invention has the function of simply taking up the fibers transported to the periphery of the carding drum without working them during their transfer from the carding drum, and supplying fibers to the first sail-forming cylinder, forming a tampon accumulator between the carding drum and the first cylinder of formation of haze, due to the recycling of fibers at the periphery of the transfer cylinder.
  • the fiber recovery function which must be ensured by the cylinder transfer accumulator is not very restrictive in terms of speed adjustment of this cylinder, and can advantageously be obtained by adjusting the speed of rotation of the accumulator transfer cylinder in a very wide speed range;
  • the rotation speed of the cylinder transfer is set so that its circumferential speed is greater than the circumferential speed of the carding drum. he thus becomes easy to adjust the rotation speed of this cylinder transfer in this very wide range, so regulate so optimal fiber supply to the first forming cylinder of the fleece, and so that this speed is adapted to desired production characteristics (production speed, mechanical properties required for the nonwoven product (grammage, isotropic, ..).
  • this accumulator transfer cylinder advantageously allows to obtain a better decoupling between on the one hand the function of carding (individualization of the fibers by carding between the drum carding the carding organs) and the training function non-woven veil provided by the successive cylinder or cylinders downstream of the accumulator transfer cylinder.
  • Another subject of the present invention is also a method for producing a nonwoven using a card of the invention. According to this method, each rotation of the carding drum of the card, we resume using the accumulator transfer cylinder plus 90%, and preferably 100% of the fibers transported to the periphery carding drum.
  • the production line shown in Figure 1 allows the parallel production of two nonwoven webs W1 and W2, which are deposited and transported on two transport belts B. At one stage subsequent to manufacture, these two nonwovens W1 and W2 are either separately consolidated by any known means of consolidation, or are for example superimposed so as to form a nonwoven more thick, which is subsequently consolidated.
  • This production line in Figure 1 includes a traditional 1 loader-loader that feeds, via a conveyor 2, a card 3 with double outlet.
  • Card 3 includes a traditional card entry, constituted by a trough 3a, a food roller 3b and a cylinder breaker 3c.
  • the breaker cylinder 3c supplies a first cylinder of rotary 3d carding, which is commonly known as a front end, and whose the surface is usually coated with a card lining or any other equivalent means allowing it to take up the fibers from the periphery of the breaker cylinder 3c.
  • the front end 3d is also provided on its periphery with several organs cardants, which allow the fibers caught in the filling to be worked of the card of this 3d cylinder, so as to individualize them.
  • these carding members are constituted by several successive pairs of a 3e sweep roller and a roller worker 3f. Downstream of these carding organs, the fibers are taken up from the periphery of the first carding cylinder 3d, and transferred to the state to a second 3h rotary carding cylinder, by a cylinder of 3g transfer, also commonly called "communicator".
  • the second 3h carding cylinder also commonly known as “Large drum” or “main drum” will be designated in the following of the present description by the terms “carding drum”.
  • This carding drum 3h is usually coated on its periphery a card lining allowing it to take up the fibers at the periphery of the communicator 3g. Also, this carding drum 3h is equipped on its periphery with carding organs (3e, 3f) identical to those fitted to the first 3d carding cylinder.
  • the invention is not limited to a card having the configuration particular of card 3 with two carding cylinders of FIG. 1.
  • the 3rd rollers and 3f could be arranged by being juxtaposed one behind the other. others alternately, according to a configuration commonly called "Garnett".
  • the sweeper and worker rollers (3e, 3f) at the the periphery of each carding cylinder could furthermore be replaced by any means of different structure, but fulfilling the same function, i.e.
  • rollers having function, in combination with the carding cylinder, to individualize 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 fixed carding points in the form of example of grooves or grooves.
  • Card 3 in Figure 1 has two outputs respectively upper and lower, each outlet comprising in the usual manner sails forming cylinders 3j, 3k.
  • the first sail forming cylinder 3j is a comb cylinder; the second 3k sail forming cylinder is a condensing cylinder.
  • These two cylinders are used in the usual way to form a condensed nonwoven web, from the fibers which are routed to the periphery of the comb cylinder 3j.
  • Each nonwoven (W1, W2) is detached from the periphery of the 3k condenser cylinder by a detaching device, conforming to the device described in the European patent application EP-A-0 704 561.
  • This detaching device essentially comprises a detaching cylinder 31, which allows detach the fiber from the periphery of the 3k condenser cylinder and place on conveyor belt B.
  • This conveyor belt is breathable, and a suction box S is provided at the stain removal area, so as to press the nonwoven by suction to the surface of the conveyor belt B.
  • the element additional 3m is a rotating brush.
  • the first cylinder for forming a non-woven veil such as the comb cylinder 3j
  • the first cylinder for forming a non-woven veil is mounted directly on the periphery of the carding drum 3h.
  • This provision makes it difficult and restrictive to adjust the speed of the 3h carding drum cylinder and forming cylinders sail.
  • the speed of rotation of the carding drum 3h must be set to allow both efficient carding with carding organs 3e and 3f, and to allow effective combing of fibers during their transfer between the 3h cylinder and the first cylinder sail training 3d.
  • the first sail forming cylinder 3j is no longer disposed at the periphery of the carding drum 3h, but card 3 has a accumulator transfer cylinder 3i between the carding drum 3h and each first training cylinder 3j of a nonwoven veil.
  • this accumulator transfer cylinder 3i is adjacent to each first 3j sail forming cylinder of each of the two outputs.
  • This accumulator transfer cylinder 3i generally has function of taking up the fibers at the periphery of the drum carding 3h, and to transfer them in the state, without making them undergo a work particular, in contrast for example with the reorientation of the fibers which is produced by a sail forming cylinder such as a cylinder comber 3j or a condenser cylinder 3k.
  • This 3i transfer cylinder plays therefore, on the one hand, a role of simple communicator vis-à-vis the carding drum 3h, and on the other hand performs a function of fiber distribution and regulating the feed rate of these fibers vis-à-vis each first veil forming cylinder 3j.
  • the accumulator transfer cylinder 3i is equipped on its periphery with a metal trim G, one of which exemplary embodiment is illustrated in FIGS. 2 and 3.
  • This gasket G is made up of a plurality of teeth 4.
  • the double arrow L represents the direction parallel to the longitudinal axis of the accumulator transfer cylinder 3i, i.e. the direction orthogonal to the plane of Figure 1.
  • Figure 3 is a sectional view of the lining of the accumulator transfer cylinder 3i according to a plan transverse to the longitudinal axis of the accumulator transfer cylinder 3i.
  • each tooth 4 of the lining G is aligned as adjacent rows parallel to the axis longitudinal of the accumulator transfer cylinder 3i; in figure 2, only two adjacent rows of teeth 4 have been shown.
  • each tooth 4 of the lining G is inclined with respect to the radius of the accumulator transfer cylinder 3i according to a angle A and is oriented in the direction of rotation of said cylinder (speed circumferential V2).
  • the teeth 4 of the lining G of the transfer cylinder were represented very schematically so to do mainly appear their inclination and their orientation above.
  • the drum of 3h carding is in known manner equipped with a card lining G 'which is usual, and whose teeth 4' are inclined relative to the radius of the carding drum 3h, and are oriented in the direction of rotation of the carding drum 3h.
  • the accumulator transfer cylinder 3i is driven in a direction of rotation which is opposite to the direction of rotation of the carding drum 3h. More particularly, the rotation speed of the transfer drum 3i accumulator is adjusted so that its speed circumferential V2 (figure 4) is greater than the speed circumferential V1 of the carding drum 3h.
  • V2 the speed circumferential
  • the fibers which are transported to the periphery of the drum carding 3h, after having been individualized by the action of the organs cardants 3e, 3f, are taken up in the lining G of the transfer drum accumulator 3i.
  • each fiber is taken up by the teeth 4 of the lining G of the transfer cylinder 3i, without being retained by the teeth 4 'of the lining G' of the carding drum 3h.
  • the result that the fibers are transferred as is, without being processed, unlike what happens in a carding structure conventional, when the fibers are taken from the periphery of the drum carding by a cylinder-type sail forming cylinder comber or counter-drum cylinder.
  • the drum transfer accumulator 3i the maximum of fibers (at least 90%) transported by the carding drum, and preferably 100% of these fibers.
  • the speed is judiciously adjusted circumferential V2 of the accumulator transfer cylinder 3i with respect to at the circumferential speed V1 of the carding drum 3h.
  • the speed ratio (V2 / V1) is greater than or equal to 1.2, and preferably greater than or equal to 1.3.
  • the absence of recycling fibers at the periphery of the 3h carding drum allows advantageously to avoid filling the card lining of the carding drum 3h. So the new fibers that are introduced at the entry of the carding drum 3h by the communicating cylinder 3g, are taken up by an empty filling, instead of a filling filled in the traditional solution.
  • the teeth of the trim carding the drum for 3 hours thus provides a better effect carding in cooperation with the peripheral carding members 3f, 3rd, and thereby better carding of the fibers transported to the periphery of the drum 3h.
  • the speed adjustment rotation of the carding drum 3h can be done almost independent with respect to the rotational speeds of the cylinders formation of sails 3d, 3k.
  • the speed of 3h carding drum rotation is set with concern only the carding quality of the fibers between this drum and the carding organs 3f, 3e.
  • the speed of rotation of the drum is adjusted 3i accumulator transfer, so as to meet the speed criterion above, which is not very restrictive (circumferential speed V2 of the accumulator transfer cylinder 3i higher than speed circumference V1 of the carding drum 3h).
  • the speeds of respective rotation of the sail forming cylinders 3j and 3k will adjusted so as to obtain the desired work for the fibers.
  • the rotational speed of the 3j combing cylinder will be adjusted from so that its circumferential speed is less than the speed circumferential of the accumulator transfer drum 3i.
  • the circumferential speed of the comb cylinder 3j is lower or equal to 25% of the circumferential speed of the transfer drum accumulator 3i.
  • the speed of rotation of the condenser cylinder 3k will be chosen so that its circumferential speed is less than approximately 80% of the circumferential speed of the comb cylinder 3j.
  • the fibers which are taken up at the periphery of the accumulator transfer drum 3i are transported by this drum to two combing cylinders 3j.
  • Each cylinder 3j comber takes part of these fibers, the other part being recycled to the periphery of the accumulator transfer drum 3i.
  • this cylinder is preferably fitted on its periphery of fairings C1, C2 and C3 ( Figure 1).
  • the card 3 comprises one or more carding members, which are mounted at the periphery of the accumulator transfer cylinder 3i.
  • the fairing C1 is replaced by one or several carding plates, which in operation of the card allow the fibers transported to the periphery of the accumulator transfer cylinder 3i.
  • the carding plates could be replaced by any carding device ensuring the same function, for example by one or more pairs of rollers worker and sweeper.
  • these carding organs are positioned in a region upstream of the fiber transfer area (in the case of a single output card) or upstream of the fiber transfer zones (in the case of a card with several outlets) between the accumulator transfer cylinder 3i and each first cylinder 3j for forming a nonwoven web.
  • this preferential region of positioning of the carding organs corresponds to the area of the periphery of the accumulator transfer drum 3i which is occupied by the fairing C1, and which extends between the carding drum 3h and the comb cylinder lower 3d.
  • the diameter d of the transfer drum 3i is less than the diameter D of the carding drum 3h. It advantageously follows that in the card of the invention, the fibers which are recycled to the periphery of the accumulator transfer drum 3i are presented more frequently to the two combing rollers 3j. Thus, if there is a periodic defect on the accumulator transfer drum, this higher frequency of recycling of the fibers makes it possible to generate in the nonwoven product periodic defects which are more difficult to perceive.
  • each 3j comber collects advantageously the fibers from above, which allows gravity to act in a good way on the combers.
  • the transfer drum 3i of the invention allows advantageously a better decoupling between on the one hand the function carding card, and on the other hand the function of forming a non-woven, and thereby better independence in the setting velocities of the elements ensuring these two functions.
  • the speed of rotation of the carding drum 3h will be adjusted so as to optimize the carding operation of the fibers by the carding organs 3e, 3f; the rotation speed of the accumulator transfer cylinder 3i will be set in sort of regulating the fiber feed rate at the inlet of each first sail forming cylinder, and sort of get also the production speed sought for the veil at exit while being set at a speed sufficient for this accumulator transfer cylinder can pick up the fibers at the periphery of the carding drum; the rotation speed of the cylinders sail training will be set to optimize the work performed on the fibers by these cylinders, and thereby optimize the quality of the nonwoven produced (isotropy, weight, etc.).
  • card 3 was used to manufacture in parallel two condensed nonwovens W1 and W2 from polypropylene fibers, of length approximately 40 mm, and of titration being worth approximately 2 , 2 dtex.
  • the diameter D of the carding drum 3h was worth 1500 mm; the diameter d of the accumulator transfer drum 3i was 700 mm; the speed of rotation of the carding drum 3 h was worth approximately 212 rpm, which corresponded to a circumferential speed V1 of approximately 1000 m / min; the rotation speed of the accumulator transfer drum 3i was approximately 590 rpm, which corresponded to a circumferential speed V2 of approximately 1300 rpm; the speed of rotation of each comb cylinder 3j was approximately 91 rpm, which corresponded to a circumferential speed of approximately 200 m / min; the speed of rotation of each condenser cylinder 3k was equal to 162 rpm, which corresponded to a circumferential speed of approximately 150 m / min.
  • the angle (A) of the teeth 4 of the lining G of the accumulator transfer cylinder 3i was approximately 30 °; the height (H) of each tooth 4 was 3.1 mm; the pitch (p) between two rows of teeth 4 was 1.6mm; the distance (e) separating two adjacent teeth 4 of the same row was 3.3 mm.
  • the invention is not limited to a double outlet card, but can of course be applied to cards comprising a single output, or to cards with more than two outputs. Also, the invention is not limited to an outlet whose cylinders sails are formed by a comb cylinder followed by a condensing cylinder, but can be used with any type known of sail forming cylinder. In particular, we can make a card with one or more cylinders for forming a nonwoven web are only combing cylinders.
