Definitions
- the present invention relates to the field of production of nonwovens using a carding machine.
- its main objects are a process and an installation allowing the manufacture of a nonwoven whose fibers have been reoriented and which is commonly known as condensed nonwoven.
- the invention finds more particularly, but not exclusively, its application to the manufacture of condensed nonwovens based on synthetic fibers (Polypropylene, Polyethylene, etc.), having a high grammage, and typically a grammage greater than 80 g / m 2 .
- Nonwovens made with a card can be classified into two categories: so-called “parallel” nonwovens (or veils), the fibers of which are essentially oriented parallel to each other to others in the machine direction (carding direction); nonwovens condensed (or scrambled) whose fibers have undergone a reorientation.
- Parallel nonwovens are in practice nonwovens whose mechanical properties show a very low isotropy, with a very low mechanical resistance of the nonwoven in the transverse direction to machine direction.
- condensed nonwovens have a mechanically, better isotropy, due to the reorientation of their fibers.
- these are nonwovens which have a heavier grammage, and which are more resistant mechanically in the transverse direction compared to nonwovens parallel.
- a condensed nonwoven uses at the output of the card, a comb cylinder juxtaposed to the cylinder principal of the carding machine (still commonly called large drum), and at least one first condensing cylinder juxtaposed with the cylinder comber.
- the combing cylinder is a cylinder presenting on its periphery a specific gasket whose teeth are oriented in the opposite direction to its direction of rotation, and which has the function of take some of the individual fibers transported by the cylinder principal of the card, and to work these fibers so as to parallelize.
- the condensing cylinder is also provided on its periphery of a specific lining whose teeth are oriented in the opposite direction to its direction of rotation, and is rotated in the opposite direction to that of the painter, and with a speed significantly lower circumferential.
- This difference in speeds allows the condenser lining to be loaded with fibers parallel from the comber, said fibers further undergoing a reorientation (or jamming) during their transfer between the two cylinders.
- This reorientation is explained by the fact that during their transfer the fibers are turned over, being retained at the front by the lining of the condenser cylinder driven at low speed, and being at the opposite rear end driven at higher speed by the trim of the painter cylinder.
- the condensed nonwoven obtained at the end of the card that is to say obtained at the output of the last condensing cylinder of the card, is then routed by any known means, to a station consolidation which is chosen according to the intended application for the nonwoven (fiber bonding by water jets, calendering, needling, ).
- a condensed nonwoven is formed by means of two conveyor belts adjacent to the cylinder card doffer, and suction in the transfer area of fibers between the painter cylinder and the conveyor belts.
- the present invention aims to propose a new method for the production of a condensed nonwoven.
- this first nonwoven a condensation operation.
- the speed differential between the transfer cylinder and the second transport surface allows an accumulation of fibers in the transfer zone between these two elements, and thereby a reorientation of the fibers of the first nonwoven.
- the condensation is not carried out during the formation of the nonwoven, but is carried out at a later stage on a nonwoven already formed and from a card. It was found that this condensation carried out at a later stage on an already formed nonwoven surprisingly provided a rate of condensation higher than that obtained with a traditional solution, without as much to harm the quality of the nonwoven produced.
- Another subject of the invention is a condensation device of a nonwoven.
- This device comprises a first and a second transport surfaces, and a rotary transfer member, which operation allows a nonwoven to be transferred from the first to the second transport surface; in operation, the speed linear of the second transport surface is less than the speed circumferential of the transfer member.
- the invention also relates to an installation for the production of a condensed nonwoven, which installation comprises a card making it possible to produce at least one first nonwoven and aforementioned condensing device.
- the card and the device condensation are arranged so that said first nonwoven produced by the card is deposited at the card outlet on the first transport surface of the condensing device.
- FIG. 1 An installation according to a preferred variant embodiment of the invention, which allows the production of a condensed nonwoven, referenced W3 in FIG. 2.
- This installation includes a card 1 with two upper outputs and lower, and a device 2 which, with reference to FIG. 2, makes it possible to forming the condensed nonwoven (W3) from a first nonwoven web (W1) from the upper outlet of card 1, and from a second web nonwoven (W2) from the lower outlet of card 1.
- Card 1 is a traditional and perfectly known card in the field of manufacturing nonwovens from fibers synthetic. For the sake of simplification, only the main elements of this card 1, necessary for understanding the invention, have have been represented, the other known elements of the card, and in particular the working rollers on the periphery of the main drum, as well as the input device for feeding the main drum, not been represented.
- this card 1 comprises a main drum 10. In the upper part and at the periphery of this main drum is mounted an upper comb cylinder 11a, followed two condensing cylinders 12a and 13a and a detaching device 14a. The upper cylinder 11a, the two condenser cylinders 12a and 13a and the detaching device 14a form the upper outlet of the card 1.
- the painter cylinder upper 11a collects in its lining part of the fibers at the periphery of the main drum 10, and performs an operation of fiber parallelization.
- the first cylinder condenser 12a is driven at a clearly circumferential speed lower than the circumferential speed of the upper comb cylinder 11a, so that condensation (or interference) occurs parallel fibers from the comb cylinder 11a, during their transfer to the lining of the condenser cylinder 12a.
- the second condenser cylinder 13a is driven with a circumferential speed lower than that of the first cylinder condenser 12a, which increases the condensation of fibers.
- this first nonwoven is routed to the periphery of the second condenser cylinder 13a up to a detaching device 14a.
- This detaching device 14a makes it possible to deposit the first nonwoven from the upper outlet of card 1 on a conveyor belt (B), the upper strand of which forms a transport surface (S1), which is driven at a linear speed predetermined constant (V1).
- V1 linear speed predetermined constant
- this detaching device 14a has already been described in the application for European patent EP-A-0704561, publication to which the man of the trade may refer for a detailed understanding of the structure and operation of this detaching device.
- this detaching device 14a comprises a detaching cylinder 15a which has an isosceles lining on its periphery or equivalent, and which has the function of taking back the first nonwoven condensed on the periphery of the second condenser cylinder 14a.
- the conveyor belt B is breathable, and the detaching device comprises a suction box 16a or all other equivalent suction means, which in operation allows to press the first nonwoven by suction against the surface of the conveyor belt B, at least in the transition zone between the detaching cylinder 15a and the conveyor belt B.
- Card 1 has a lower outlet, which is identical from a structural point of view, at the upper exit previously described.
- This lower outlet consists of a comb cylinder lower 11b, of two successive condenser cylinders 12b and 13b and a detaching device 14b, which allows the nonwoven to be taken up condensed at the periphery condenser cylinder 13b and deposit said nonwoven condensed on a conveyor belt B '.
- the upper strand of the conveyor belt B ' forms a transport surface S2, and is driven with a predetermined constant linear speed V2.
- two sails are thus produced in parallel non-woven: the first non-woven web W1 previously described, and a second non-woven veil, which comes from the lower outlet of the card 1 and which is referenced W2 in FIG. 2.
- the condenser device 2 of the invention comprises, in addition to the two transport surfaces S1 and S2 previously described, a member rotary transfer 20.
- this transfer member comprises a rotary cylinder 21 smooth.
- smooth cylinder is meant a cylinder having no lining on its periphery, as opposed to the other cylinders of the card 1, and in particular to the main drum 10, to the cylinders comb 11a, 11b and the condenser cylinders 12a, 13a, 12b, and 13b.
- the cylinder 21 is a perforated cylinder, inside from which a suction sector A is mounted.
- This suction sector A is preferably adjustable, and in operation of the device, this suction sector A, after having been adjusted in position, is fixed.
- a tube 22 which once adjusted in position is fixed when the cylinder 21 is rotated, and which is provided with a slot longitudinal 23.
- On the outer face of this tube 22 are fixed two walls 24 delimiting the suction sector A.
- the interior of the tube 22 is placed under vacuum, being connected by example to a fan, so that we create in sector A a suction allowing the entry of an air flow from the outside towards the inside of the cylinder 21, in a region limited to the sector suction A.
- the cylinder 21 is mounted so as to be adjacent to the roller downstream end 25, used for driving the strip conveyor B. Also, this cylinder 21 is positioned so that it is placed above and near the surface of transport S2.
- card 1 produces in parallel two condensed nonwovens W1 and W2 respectively on its upper and lower outputs.
- the first nonwoven condensed W1 comes from the upper output of card 1, and is deposited on the transport surface S1 upstream of the cylinder transfer 21;
- the second nonwoven W2 comes from the lower outlet of card 1 and is deposited on the transport surface S2 upstream of the transfer cylinder 21 of card 1.
- These two nonwovens W1 and W2 are routed in parallel respectively by the surfaces of transport S1 and S2 to the transfer cylinder 21.
- the cylinder 21 is rotated with a circumferential speed (VT) [linear speed of the external surface of cylinder 21] which is equal to or very slightly greater than the speed linear (V1) of the transport surface S1, so that the cylinder 21 incorporates on its periphery the first condensed nonwoven W1, without destroying the structure of this nonwoven, and subjecting it to a very low stretch, and routes it to the second transport surface S2.
- VT circumferential speed
- V1 speed linear
- the suction sector A of the cylinder 21 is positioned so as to allow this first nonwoven to be maintained under the suction effect against the surface of the cylinder 21, during its transfer between the first transport surface S1 and the second transport surface S2.
- the linear speed V2 of the second surface transport S2 is significantly lower than the circumferential speed (VT) of cylinder 20 and therefore at the linear speed of the first transport surface S1, so that it mainly occurs condensation (or scrambling) of the fibers of the first nonwoven W1, during its transfer between the cylinder 21 and the conveyor surface S2. More specifically, when the fibers of the nonwoven W1 arrive in the transition zone between the cylinder 21 and the transport surface S2, from made of the lowest speed of this transport surface S2, said fibers are suddenly slowed down and accumulate in this area of transition.
- VT circumferential speed
- a condensed nonwoven W3 is thus obtained of greater thickness, formed by superposition of the nonwoven lower W2 with fibers from the nonwoven W1 which have been strongly reoriented.
- the weight of this W3 nonwoven is greater than the sum of the weights of nonwoven W1 and W2.
- the condensation device 2 comprises a suction box 26, or equivalent, which in operation allows to create across the transport surface S2, at least in the area of transition between cylinder 21 and transport surface S2, a flow suction, which preferably extends over the entire width of this transport surface S2, which allows the fibers to be plated transported against the conveyor surface S2.
- the weight of the nonwoven W3 obtained at the output of the device condenser 2 of Figures 1 or 2 depends on the weight of the two nonwovens W1 and W2 from the upper and lower outlets of card 1, but also and above all the speed differential between the transport surface S2 and the circumferential speed of the cylinder 21.

- the lower comb cylinder 11b was driven at a circumferential speed of the order of 100 m / minute.
- the two condenser cylinders 12b and 13b were driven respectively with circumferential speeds of 52 m / minute and 30 m / minute.

- the circumferential speed of the upper comb cylinder 11a was of the order of 161 m / minute; the circumferential speeds of the two condenser cylinders 12a and 13a were respectively of the order of 84 m / minute and 49 m / minute.

- the transfer cylinder 20 was driven with a circumferential speed (VT) of the order of 105 m / minute, or a ratio (VT / V2) of the offer of 5.25.
- the weight of the nonwoven W3, at the outlet of the condensation device 2 was of the order of 160 g / m 2 .
- the invention is not limited to the particular example of embodiment which has just been described with reference to FIGS. 1 and 2.
- the transport surface S2 is flat, at least in the transition zone between the cylinder 21 and the said transport surface.
- a transport surface could be used S2 curve.
- the rotary transfer member 20 is not necessarily a cylinder, but may be replaced by any means fulfilling the same transfer function; it can in particular be a roller driven by a conveyor belt.
- the organ of transfer 20 is suction. Indeed, by removing the aspiration (sector suction A), or with too low suction, it was found in many cases that faults appeared quickly in the structure of the nonwoven produced. In practice, we will adjust the flow of air sucked in sector A by increasing it until the disappearance of defects in the structure of the nonwoven.
- the invention is not limited to the formation of a nonwoven from two sails. They can advantageously be used also to make a condensed nonwoven from a single nonwoven W1. In this case, the transport surface S2 does not transport no veil upstream of the transfer cylinder 21.
- suction box 26 implemented at the transition zone between the transfer member 20 and the surface of transport S2 is optional, in particular in the case of a single nonwoven W1. This suction improves the blocking one by compared to the other of the two nonwoven webs W1 and W2 during their overlay.
- the invention is not limited to the production of a nonwoven higher weight W3 from a single nonwoven (W1), or several (W1, W2) condensed nonwovens.
- the veil nonwoven W1 could be a parallel veil coming directly from a comb cylinder, and not having been previously condensed by condensing cylinders. The same is true of the W2 veil.
- the invention mainly finds its interest in the production of heavy nonwovens (weight greater than 80 g / m 2 ), because it allows high speed ratios between the transport surface (S2) and the transfer organ 20, and thereby obtaining significant condensation rates, without affecting the quality of the nonwoven produced.
- the ratio (VT / V2), between the circumferential speed (VT) of the rotary transfer member and the linear speed (V2) of the second transport surface (S2 ) is greater than 2, and preferably greater than or equal to 3. This speed ratio is fixed on a case-by-case basis as a function of the desired condensation rate.
