Definitions
- the invention relates to a system and a method for the production of nonwoven fabric, based on glass fibers and thus produced nonwoven fabric, in particular as a semi-finished or final product, in particular for use for insulation and / or insulating purposes.
- the document DE 699 22 192 T2 relates to the production of artificial glassy fibers (MMVF) webs with which the construction of the web is to be optimized.
- the apparatus comprises two centrifugal spinners having at least one shredding rotor mounted for rotation about a substantially horizontal axis, means for entraining the fibers of each spinner in a stream of air around at least one shredding rotor of each spinner, the stream of air having a flow field and thereby provides a single cloud of air entrained fibers.
- the fibers are collected as a web and then cross-laid on the web to form the web.
- Glass fiber mats are also known (eg from DE 37 21 715 A1), which are provided on one side with an aluminum lamination. Corresponding aluminum laminations are However, consuming and expensive and can be detrimental to necessary electrical contacts. Furthermore, due to the lamination, which is usually present on only one side, the mounting position must be given special attention.
- non-wovens are produced which comprise a mixture of natural fibers, e.g. Cellulose fibers of cotton or loosened, already mechanically and / or chemically treated wood cellulose (fluff pulp), synthetic matrix fibers such. Polyester, polypropylene or viscose as well as synthetic binding fibers, e.g. So-called bicomponent fibers and, for example, as absorbent so-called superabsorbent polymers in particle (SAP) or fiber form (SAF) comply and, for example, as a semi-finished for the production of diapers and sanitary napkins, absorbent pads for
- An important step in the production of such a web is to deposit the fiber mixture as evenly as possible on an air-permeable transport or conveyor belt. This depositing takes place with the aid of a forming head in which the fibers are mixed, with intermeshing needle rollers with longitudinal axes aligned parallel to one another being arranged in a fiber processing space and which can rotate about their respective longitudinal axis.
- the supplied by an air flow fibers enter between the intermeshing needle rollers through into the interior and also leave the interior between the intermeshing needle rollers.
- the needle rollers should contribute to the homogenization of the fiber distribution.
- the fibers are deposited on a conveyor belt as a fiber bed, which have a substantially same orientation. Subsequently, the fiber bed can be pressed.
- EP 0 384 551 B2 describes a carding machine for producing randomly oriented or longitudinally oriented fiber fleece, with at least one draw-in roll or the like, optionally a preliminary roll running in the same direction and at least three downstream of the roughing rolls, in the same direction with each other and preferably in opposite directions to the preliminary roll Working drums same diameter described.
- Two working drums are in mutual engagement and their relative speed and / or mutual distance for controlling the proportion of the fiber material which can be stored back on the respective working drum on the one hand and the fiber material which can be transferred to the downstream working drum on the other hand can be adjusted.
- the working drums are covered with cover boxes and are all arranged successively around the circumference of at least one central roller running in the same direction, which has a larger diameter compared to the working drums.
- the relative speeds and / or the distance of the working drums on the one hand and the central roller (s) on the other hand are designed adjustable.
- This device has a complicated structural design.
- a disadvantage of the aforementioned solutions is that over the width unevenly supplied fiber volume can lead to an irregular fiber fleece.
- the object of the invention is to develop a plant and a process for the production of fiber fleece based on glass fibers and a nonwoven fabric produced therewith, whereby a manufacturing method is provided with a simple structural design, which has a uniform distribution of the fibers over the entire width ensures the nonwoven fabric, wherein a single-layered homogeneous nonwoven fabric is created, which has excellent insulation and / or insulating properties.
- the inventive plant for the production of nonwoven mats based on glass fibers in particular for use for insulation and / or insulating purposes according to the invention consists of
- a fiber opening device for the dissolution and oriented or non-oriented orientation of the glass fibers and formation of a fiber web
- a first unit for reorienting the oriented or unoriented fibers of the batt into fibers occupying a random orientation, increasing the volume of the batt / decreasing the density of the batt; a climbing belt (transport means) which conveys the batt from the fiber opening device to the first unit,
- the fiber opening device is preferably a carding unit for the resolution and oriented orientation of the fibers, wherein the carding unit outputs a batt with longitudinally oriented fibers,
- the carding unit can be replaced by a novel aggregate of the fiber opening.
- This aggregate of fiber opening allows the output of a non-oriented fiber batt.
- this unit can also be executed in multiple stages, so that, for example
- the carding unit may be a conventional carding unit and is arranged in front of the first unit.
- the second unit, in which the nonwoven fabric is formed, is the first unit, in which the reorientation of the fibers of the batt occurs in a random orientation, downstream.
- the first unit is arranged above the second unit.
- the carding unit has at least one feed roller for picking up the fibers and at least two spaced-apart work rolls and a discharge roll, wherein the pickup roll, the work rolls and the discharge roll are arranged around a central roll. With the work rolls, the fibers are separated and aligned in a defined direction.
- the diameter of the central roll is preferably greater than the diameter of the feed roller, the work rolls and the discharge roller.
- the diameter of the delivery roller is selected to be larger than the diameter of the feed roller and the work rolls.
- the delivery roller is also called transfer roller. It has a pure transport function, ie the fibers should be transported and not compacted or processed in any other way.
- each work roll is advantageously preceded by a roll of smaller diameter.
- These rollers are also called turners, which have the task of removing the fiber excess on the work rolls and to press this back on the central roll.
- the smaller diameter is chosen so that not all fibers from the work rolls, but only the excess is withdrawn.
- the carding unit leaves a batt with oriented fibers at high speed.
- this carding unit can be replaced by a fiber opening and distribution unit.
- This fiber opening and distribution unit consists essentially of fiber opening aggregate and fiber distribution system.
- the fiber-opening unit is characterized by at least one feed roller and a central roller which is equipped with needles or hook-like elements.
- Around the central roller at least one smaller roller is arranged, which in turn is equipped with needles or hook-like elements.
- at least one rigid needle bar is arranged in front of the smaller roller, which is combed through by the central roller.
- the fibers can be removed by air or mechanically via a delivery roller.
- the fiber-opening unit can be followed by a single-stage or multi-stage fiber distribution system.
- This fiber distribution system is characterized by the combination of a fiber storage with a subsequent uniform distribution of the fibers across the working width.
- the uniform distribution of the fibers over the working width is mainly due to the interaction of a needle or hook-like stocked band with appropriately arranged tee and back wiping rollers, the fibers are also fed via a conveyor belt needle-like or hook-like equipped band.
- the uniform monolayer batt is transported at a high speed via a feed belt.
- the first unit there is a reorientation of the uniformly aligned fibers of the batt into a random orientation.
- the volume of the batt is increased by a multiple, so that many air pockets are present in the batt.
- the first unit for reorienting the fibers of the batt in a random position at least two rollers provided with needles and / or hooks.
- the rollers provided with needles and / or hooks and a stream of air to reorient the fibers into a random orientation in the first unit.
- the batt is transferred after the reorientation of the fibers into a random orientation from the first unit to the second unit, in which the formation of the homogeneous single-ply non-woven fabric is carried out with random fibers.
- the second unit preferably builds the nonwoven fabric on a storage belt by means of negative pressure.
- the thickness of the homogeneous nonwoven fabric can be adjusted by changing the advance speed of the storage belt.
- the nonwoven fabric is dispensed from the second unit and can then be fed to a solidification device.
- a non-woven fabric mainly of glass fibers can be produced, which is then fed to a thermal consolidation.
- other fibers or similar substances can be introduced, which then lead to a mixed fiber fleece.
- the introduction of these materials can be done with known powder, granular or fiber scatterers on or in the device according to the invention.
- the nonwoven fabric can be provided with a surface seal on one or both sides. This is done in a coating device by means of water glass, plastic, adhesive or resin.
- a homogenous single-layer fiber fleece with predominantly glass fibers in random orientation is produced, the fiber fleece consisting of fibers which are reoriented from an oriented or an unoriented layer into a random orientation with an increase in volume / density reduction.
- the homogeneous fiber fleece contains many air pockets.
- nonwoven fabric which has a very low basis weight or a low density / bulk density.
- minimum densities of up to 15 kg / m 3 are possible if thermal bonding of the nonwoven fabric takes place and gross densities of up to 50 kg / m 3 for needled nonwoven fabric, which was previously unachievable with conventional systems.
- the previously possible density / bulk density in generic methods with thermal consolidation is a minimum of about 30 kg / m 3 and a minimum of about 80 kg / m 3 for needled products.
- the homogeneous single-ply fiber fleece consists in particular of endlessly drawn fibers (preferably glass fibers) with a uniform filament diameter, wherein different fibers can be combined and also natural fibers can be used in combination with synthetic fibers for the production of the nonwoven fabric.
- the homogeneous monolayer nonwoven fabric may optionally be infiltrated with a binder and formed into a 3-dimensional fiber mat by subsequent reshaping.
- the nonwoven fabric is advantageously provided on one or both sides with a surface seal.
- the surface seal is e.g. sprayed on and is curable and consists e.g. made of water glass, plastic, resin or glue.
- the surface seal eliminates the need for an otherwise required aluminum lining (which must be recycled separately). In contrast, the surface seal is much easier and less expensive to produce.
- a fiber opening device a resolution and separation of the glass fibers into a batt with an oriented or non-oriented orientation of the glass fibers takes place.
- the batt is fed via a riser (transport means) of a first unit, in which a reorientation of the fibers of the batt into fibers, which take a random position, whereby the volume of the batt increases / the density of the batt is reduced.
- the laying of a homogeneous single-layer fiber fleece with fibers in random orientation takes place from the fiber pile of the first unit.
- the basis weight of the nonwoven fabric produced is a multiple of the basis weight of the batt.
- the basis weight of the nonwoven fabric is adjustable by the speed of the storage belt. If the speed of the delivery belt is reduced compared to the speed of the belt, a higher nonwoven with a higher basis weight is produced.
- By reducing the advance speed of the storage belt it is thus possible to achieve up to a 50-fold increase in the pile weight of the produced nonwoven fabric in comparison to the pile weight of the nonwoven fabric, which is supplied to the first unit, thereby producing a single-layered homogeneous fiber non-woven fabric. It is also possible to infiltrate into the batt binder, granules or other additional fibers individually or in combinations.
- the non-woven fabric according to the invention which is based on glass fibers as a semi-finished or final product, especially for insulation and / or insulating uses, is a homogeneous single-layer fiber fleece of glass fibers, wherein the glass fibers from an oriented or non-oriented layer (in the batt) in a random orientation is reoriented by increasing the volume / reducing the density (of the nonwoven fabric).
- the nonwoven fabric has a minimum density of up to 15 kg / m 3 , when thermal bonding of the nonwoven fabric takes place. If the fiber fleece was needled, the minimum density is up to 50kg / m 3 . Furthermore, the nonwoven fabric has a uniform filament diameter of the glass fibers (preferably at the same length). consists of endlessly drawn glass fiber, which was preferably separated into fibers of the same length, which then form as staple fibers the starting base for the production of the nonwoven fabric.
- nonwoven fabric on one or both sides with a surface seal which is in particular curable and preferably consists of waterglass, plastic, resin or adhesive.
- binder, granules or other additional fibers can be infiltrated individually or in their combinations into the nonwoven fabric.
- the binder makes it possible to produce shaped bodies from the nonwoven fabric by three-dimensional shaping (also in the layer / sandwich construction with other materials).
- the nonwoven fabric can, after appropriate cutting, be used as an insulating and / or insulating mat and / or as a reinforcing or reinforcing part and, as already described above, be shaped three-dimensionally.
- a nonwoven fabric is created, which has a very large volume.
- Made from insulating mats or insulation mats have excellent insulation or insulation properties due to the many air pockets.
- the thickness of the insulating mats can be significantly reduced.
- a conventional insulating mat with aluminum lamination with a thickness of 20 mm and a density of 32 kg / m 3 can be replaced.
- the insulating mats are used for example in domestic or kitchen appliances or in vehicles for insulation and / or insulation purposes.
- moldings therefrom which serve, for example, as support and / or stiffening or reinforcing elements and are used in particular in the vehicle sector.
- the thinner insulation mats By using the thinner insulation mats, it is possible to increase the cooking space, for example in kitchen stoves.
- the insulating mats from the novel fiber Fleece which have a thickness of 20mm as the previous insulating mats, the energy consumption can be significantly reduced.
- the fibers used are in particular drawn glass fibers with a uniform filament diameter of 0.009 to 0.025 mm and a length of up to 200 mm. However, it is also possible to use or to incorporate other organic or inorganic fibers.
- FIG. 1 is a schematic diagram of a plant for the production of nonwoven fabric using a carding unit 1 in a three-dimensional representation
- FIG. 2 shows the side view according to FIG. 1.
- FIG. 3 shows a schematic diagram of a plant for the production of nonwoven fabric using a carding unit 1 and with a subsequent coating device and a solidifying device in side view,
- FIG. 4 shows the basic illustration of a plant for the production of nonwoven fabric using a fiber opening and distribution unit 10 in the front view.
- the system consists of a fiber opening device in the form of a carding unit 1, which recycled and already partially opened fibers are supplied.
- the starting base thereby form bundle-like continuous glass fibers in the form of staple fibers with a length of up to 200 mm with a diameter of 0.009 to 0.025 mm, which were produced from drawn continuous fibers.
- the carding unit 1 In the carding unit 1, the singulation into individual fibers and their oriented orientation takes place.
- the carding unit 1 has for this purpose a receiving roller 1 .1 for receiving the fibers, two spaced apart work rolls 1.2, each of which a roller 1.3 (Wender) is assigned, and a discharge roller 1 .4.
- the rollers 1.1 to 1.4 are arranged around a central roller 1.5.
- the single-ply fiber web F (see FIG. 3) produced there from the glass fibers passes onto a feed belt / riser 2 and is transported at high speed through the latter to the first unit 3, in which the fibers oriented substantially in one direction of the batt F be reoriented into a random orientation.
- the volume of the batt F is substantially increased and can be mixed with other materials.
- the fibrous web F can be infiltrated with a binder, granules G (eg of thermoplastic material) or other fibers from a scattering unit 2.1, which is arranged, for example, above the riser 2 (see Figure 3) or the scattering unit 2.1 is placed on or in the unit 3 (not shown).
- a scattering unit 2.1 which is arranged, for example, above the riser 2 (see Figure 3) or the scattering unit 2.1 is placed on or in the unit 3 (not shown).
- a plurality of scattering units for example a scattering unit for introducing binder, a further for introducing other fibers, etc.
- the second unit 4 into which the fibrous web F (see FIG. 3) now passes and in which a homogeneous single-layer fibrous web FL is laid / formed from the fibers located in random orientation.
- the first and the second unit 3, 4 are indicated only schematically.
- the thickness and weight of the nonwoven fabric FL can be varied by different speed settings. It should be emphasized that up to 50-fold increase of the pile weight per unit area can be achieved without the usual crossing or crossing.
- the non-woven fabric FL is formed on a storage belt 7, which is transported by a conveyor belt 8 and e.g. is wound on a roll (not shown).
- the homogenous single-layer fiber fleece FL thus produced can subsequently be coated by means of a coating device 5 for surface sealing with water glass, plastic, adhesive or resin.
- the non-woven fabric FL is solidified by means of solidification 6, e.g. by needling or thermally.
- the sealing of the nonwoven fabric FL can also be done only after solidification.
- nonwoven FL mats are made or cut, which can be used in a variety of ways for thermal insulation and / or sound insulation.
- the non-woven fabric FL or the mats produced therefrom have a soft, silk-like surface that no longer resembles glass fibers. Furthermore, in particular by the sealing and the needling no more glass fibers are released undesirable.
- the fiber opening and distribution unit 10 consists essentially of one or more fiber opening aggregates 11 (here two) and one or more fiber singulation plants 12 (here three) and replaces the entire conventional fiber opening path via pre-opening and carding (carding unit 1 and devices arranged in front of it for partial singling and opening the fibers). At the same time a uniform distribution over the entire working width is realized by the immediately successively arranged Faseraposzelungsanlagen 12. It is thus possible to produce an even higher volume of the batt F.
- Each fiber-opening unit 1 1 here has two feed rollers 1 1 .1 and a central roller 1 1 .2, which is equipped with needles or hook-like elements (not labeled).
- a central roller 1 1 .2 Around two smaller rollers 1 1.3 are arranged, which in turn are equipped with needles or hook-like elements (not labeled).
- a rigid needle bar 1 1.4 is arranged between the feed rollers 1 1. 1 and the following smaller roller 1 1.3, which is combed by the central roller 1 1.2.
- the fibers may be drawn off by air or mechanically via a delivery roller (not shown).
- the two fiber-opening units 1 1 here the three fiber distribution systems 12 are connected downstream, which are arranged directly behind one another.
- the fiber distribution systems are each a fiber storage 12.1 provided with a subsequent uniform distribution of fibers over the working width by cooperation of a needle or hook-like stocked tape 12.2 with appropriately arranged tee and remindstreifwalzen 12.3, the fibers also on a conveyor belt 12.4 the needle or hook similar equipped band 12.2 are supplied.
- the single-layer fiber web F which is formed from the separated glass fibers, also passes via a riser 2 into the first unit 3, in which the fibers of the fiber web F are reoriented into a random orientation.
- the second unit 4 into which the fiber web F (see FIG. 3) now passes and in which the formation / laying of the homogeneous single-layer fiber web FL takes place with fibers located in random orientation.
- the second unit 4 can also build up the nonwoven fabric by means of negative pressure.
- the fact that already consists of fiberglass fibers F has a high volume, the volume of the laid with the second unit 4 batt FL is increased from the fibers in dislocated even more, whereby the insulating properties even more than when using a Improve clutter unit.
- binder / granules e.g., thermoplastic / phenolic material
- other fibers e.g., polyester / phenolic material
- thermoplastic / phenolic binder is preferably also carried out over the riser 2 and / or in the first unit 3 by means of a scattering unit, not shown.
- the admixture of other fibers can be done at the beginning of the processing line and / or in the first unit.
- a fiber opening device in the form of a fiber opening and distribution unit (according to FIG. 4) and a fiber opening device in the form of a carding unit 1 (FIGS. 1 to 3) in front of the unit 3 can be combined with one another.
- at least one fiber opening and distribution unit and then at least one carding unit can be provided first.
- the mats produced from the nonwoven fabric are largely elastic and thus return to their original thickness after being compressed.
- a fiber mat By selectively introducing binder, granules or other fibers, a fiber mat can be produced after appropriate thermal or chemical solidification, which can take a 3-dimensional shape by subsequent forming.
- the essential field of application are preferably kitchen appliances for private and / or commercial needs, in which a good thermal insulation is required, e.g. Cookers, microwaves, hot air ovens, washing machines, dryers, etc.
- the glass fiber mats in vehicles or in the construction industry.
- simple single-layer glass fiber mats which may be coated on one or both sides (for example with waterglass) and which are used, for example, in cookers or in other aforementioned fields of application.
- the glass fiber mats made from the nonwoven fabric can form the starting base as a semi-finished product for the production of moldings with a lamination or other layer structure.
- the glass fiber mats are infiltrated with a binder and in particular compressed together with the other materials to form a molding.
- the non-woven fabric can be delivered to a consumer as uninterrupted goods, eg on rolls, which then cuts and processes them. It is also possible to process the nonwoven fabric at its manufacturer to semi-finished or final products.
- Fiber opening device (carding unit 1 and / or fiber opening and distribution unit 10) in which there is a separation and distribution of the glass fibers to a batt F of loose glass fibers
- a fiber fleece FL is produced which has only one layer and is homogeneous and thereby has a greater thickness , as the batt F, which forms the starting base.
