Definitions
- the invention relates to a method for producing a mat from a natural fiber fleece, which contains thermoplastic fibers, and at least one further fleece plastic fibers; and a machine for performing the method.
- DE-C 196 02 551 specifies the components from which the thermoformable mats are composed, but it says nothing about how these mats are manufactured. It can be assumed that the individual fleeces are simply placed on top of one another.
- DE-C 195 41 524 describes a machine for connecting a nonwoven web made of thermoplastic synthetic fibers and a film web. The nonwoven web and the film web are heated separately to different temperatures.
- the invention has for its object to a method for producing a mat create that is simple in its process and a secure connection of the individual fleeces with each other. No adhesives or other aids should be used become. Needling of the layers should also be avoided. There is also the Task to design a machine to carry out the process.
- the solution of the problem is According to the invention achieved in that the prefabricated nonwovens together one or continuously supplied to several heat sources and immediately connected to the heating are then passed between press rolls.
- the prefabricated nonwovens are continuously fed to the heating and the press rolls, the heating and the pressure of the press rolls are such that only a connection between the Surfaces of the fleeces are made.
- the nonwovens are drawn off endlessly from nonwoven winding rolls and fed to the heat source. As soon as a fleece is unwound from the winding roll, its end will be at the beginning of the Fleece connected to a change roller and an interruption of the continuous Procedure avoided.
- the nonwovens are needled onto their winding rolls before being rolled up, resulting in a firm one Compound of fibers leads.
- the natural fiber blend contains thermoplastic fibers with a low Melting point, while the or the plastic fiber fleece made of thermoplastic fibers different, i.e. lower and higher, melting point exist.
- the heat source is preferably oriented so that it faces the mutually facing Non-woven sides act directly. This ensures that only the on by heating the surface of the nonwovens thermoplastic fibers with low Melting point are melted and form a connection with each other. All other Thermoplastic fibers remain unchanged and only become higher with the later ones Temperatures and pressures fused plastic deformation.
- Polypropylene fibers are used as fibers with a low melting point and as fibers with higher melting point polyester fibers and / or polyacrylic fibers used.
- Hot air is preferably used as the heat source.
- the hot air is on the Inflated fleece surfaces at a temperature of approx. 600 ° C. In doing so immediately in front of the press rolls the fleece is heated superficially by the press rolls be pressed together, so that the softened fibers of the nonwovens with each other can connect.
- the nonwovens are processed with the same edge, i.e. equal to the edge Heat source are supplied.
- the edge trim of the Matt waste is avoided or kept to a minimum. At the It is best if the necessary edge trimming is done on the fleece Their connection with each other takes place, as this makes the waste generated more uniform Structure are, depending on the type of fleece, and can be easily recycled. The waste is at added to the nonwoven production.
- the mat is rolled up into a roll. If necessary, you can also use slitters are used and the mat is divided into smaller rolls of predetermined width.
- the machine for performing the method consists essentially of Roll holders for the nonwovens, a pair of press rolls arranged at a distance from it with heat sources located directly in front of it between the fleeces and a winding device for the finished mat.
- the roll holders allow a continuous Deduction of the fleeces from the rolls on which they are delivered.
- heat source is generally understood to mean it any facilities, e.g. ultrasonic devices are also used, which soften the fibers.
- Guide rollers for the individual nonwovens are provided in front of the press rolls. The roles keep the nonwovens apart so that they only pass through the roller during the pressing process be brought together. Just before that is the heating zone. That is necessary for the melted fibers not prematurely before the bonding process between the rollers cooling down.
- a pair of draw rollers is connected downstream of the press rolls. They have the task of the fleeces pull evenly from the fleece rolls through the nip of the press rolls therethrough.
- the heat source is made up of individual in series side by side arranged slot nozzles formed with heating device.
- the slot nozzles close tightly to each other and the entire width of the fleece is detected.
- the air is passed through the nozzles a compressed air line supplied.
- One row of nozzles is between two fleeces provided and the nozzle slots are directed to the point at which the two fleeces meet.
- the air is heated at the nozzle connection points between the Nozzles and the airflow. It is of course also conceivable to heat the air in front of the Entry into the distribution line.
- heating the air in front of the nozzles has the advantage of being more uniform Heating.
- each fleece there are two roll holders and one in a row Transfer station provided for connecting the fleece ends.
- a transfer station For endless processing the fleece it is necessary that the fleece end of the used roll with the Fleece start of the new role is connected.
- the transfer stations are with Devices for connecting the fleece ends are equipped. The ends can go through Sewing, gluing or stapling are connected to each other.
- Edge cutters can be used to achieve a straight edge of the mat. So that the waste is simply added to the Nonwoven raw materials can be recycled, it is beneficial if the individual Fleece edge cutters in front of the press rolls can be assigned. The accruing Waste is then very uniform and can be added to the carding machine.
- the mat produced by the process is characterized by a natural fiber fleece Natural fibers and synthetic fibers with a low melting point as the middle layer, that of two Plastic fleece from plastic fibers with low and high melting point as Outer layers is covered. Since in the present method only those to the connecting surfaces of the nonwovens existing plastic fibers with low When the melting point is softened, the fibers inside the fleece remain unchanged. Only the facing sides of the fleeces are softened by the low-melting plastic fibers connected together.
- the process can of course also be used for mats with a different structure getting produced.
- foils can also be incorporated.
- Fig. 1 shows the basic sequence of the method.
- Rolls 1 through 6 are nonwoven rolls, such as they are delivered.
- the fleeces 7, 8 and 9 are drawn off from these rolls 1 to 6 and the press rolls 10 and 11 fed.
- the upper fleece 7 is a plastic fleece
- the middle one Fleece 8 is a natural fiber fleece
- the fleece 9 is again a plastic fiber fleece.
- Heat sources 12 and 13 arranged Immediately after heating and softening the in the Non-woven thermoplastic fibers with a low melting point are the Nonwovens 7 to 9 are compressed by the press rolls 10 and 11, creating a good Connection between the fleece surfaces occurs.
- the fleeces 7 to 9 and the ones from them formed mat 14 are pulled by the pull rollers 15 and 16.
- the finished mat 14 will wound up into roll 17 and made available for further transport.
- the double fleece winding rolls 1, 2; 3, 4 and 5, 6 indicate that a flying change of Rolls 1 through 6 takes place.
- the fleece end becomes one the rolls 2, 4, 6 connected to the fleece beginning of the associated roll 1, 3 and 5, so that the deduction can continue indefinitely.
- the Transfer stations 18, 19 and 20 are provided for the connection of the fleece ends.
- the fleece ends are sewn together here.
- the roll holders 30 are also double and allow a quick change of Fleece rolls 1 to 6 too.
- An edge cutter 21, 22, 23 is assigned to each fleece 7, 8 and 9 exact width of the fleece 7 to 9 is determined.
- the nonwovens 7, 8, 9 are the press roll nip fed between the two printing rollers 10 and 11. A low tension holds the Nonwovens in the given position.
- the fleeces 7, 8, 9 are needled and form a relative firm bond.
- the heat sources 12, 13 are hot air slot nozzles with heating devices (see FIGS. 2 and 3). Compressed air is supplied to the nozzles via the fan 27 and a compressed air line 28.
- the press roll area is shown enlarged.
- the natural fiber fleece 8 becomes approximately inserted horizontally between the press rolls 10 and 11. Be from above and from below the plastic fiber fleeces 7 and 9 brought up.
- the natural fiber fleece 8 is considerably thicker than the plastic fiber fleeces 7 and 9.
- Hot air is applied to the inner surfaces 34 to 37 of the nonwovens 7, 8 via the slot nozzles 32 and 33 and 9 blown, in the area immediately in front of the nip 42.
- the Air is fed through the compressed air line 28 to the distributor lines 38 and 39 and from distributed there to the individual slot nozzles 32, 33.
- Each slot nozzle 32, 33 is with a Heating device 40, 41 provided.
- FIG. 3 shows a top view of the area according to FIG. 2.
- the compressed air line 28 becomes compressed air supplied to the distributor line 38. From the distributor line 38, the individual slot nozzles 32 fed. The air is heated in front of the Slot nozzles 32 attached heaters 40. Behind the roller 10, in Seen direction of movement of the nonwovens, is a cutting bar 42, which is used to divide the Mat 14 serves in four equal paths.
- the middle layer 50 mainly consists of natural fibers, e.g. Kenaf, hemp, flax, jute and sisal, in which polypropylene fibers are embedded.
- the two outer layers 51 and 52 are made of the fleeces 7 and 9 formed and consist of polyester and polypropylene fibers. On the to the left of the figure are the outer layers 51 and 52 just before connection to the Middle layer 50 shown. The hot air causes only the polypropylene fibers in the Fleece surfaces 34, 35, 36, 37 are softened and bonded together.
