Definitions
- the invention relates to a paper machine wire for the wet end of a paper machine according to the preamble of claim 1.
- Such paper machine screens which have one or more layers or in the form of a composite fabric can be formed and generally a woven or non-woven, textile or Non-textile fabrics, preferably a fabric, are known from practice. They serve to dewater an aqueous fiber suspension and this to the press section of the To manage paper machine.
- the known paper machine screens of all types of construction are characterized in that the side of the screen facing the paper by the side predetermined by the weave of the fabric Structure is determined. If possible, the surface structure of the fabric should not have any markings left on paper. Thus there are reduced topographical markings of the sieve particularly in demand due to the sensitive types of paper.
- the retention ability also called retention
- it can by the drainage and guide elements of the paper machine from the running or wear side of the Tissues are washed out, which also leads to low retention values to lead.
- a paper machine screen according to the preamble of claim 1 with a textile fabric in the form of a fabric is known from US-A-5 077 116.
- the fleece layer is made up of individual fibers and laid loosely on top of the fabric and connected to the threads of the fabric forming the surface of the fabric.
- the nonwoven layer adheres to the Adapts the surface of the fabric so that the structure of the fabric is modeled becomes. It follows that the surface of the nonwoven layer is similar to the surface of the fabric does not form a uniform horizontal level.
- the invention has for its object a paper machine screen of the type mentioned to create, in which the topographic marking tendency is reduced to a minimum and the Retention values in paper production are improved.
- the nonwoven layer is permanently less strong in some areas than in others Areas compressed, the nonwoven layer being less compressed in the areas, in which corresponding areas of the surface of the paper-facing side of the textile or non-textile fabric in a predominantly the surface of the fabric Level.
- the fleece layer therefore has a completely uniform, flat surface on.
- the permeability of the fleece can be determined by the fiber orientation and the Adjust the structure of the fleece. It follows that with such a paper machine screen produced paper can be produced almost without any markings and therefore meets the highest demands enough. It also follows from this that the retention capacity of the fibers and the auxiliaries and additives the fiber suspension depending on the density or the pore sizes of the selected Fleece can be largely adjusted. This also applies to the ability of the non-woven layer to To dewater pulp suspension.
- the nonwoven layer has a thickness of preferably 0.1 up to 1 mm and an essentially uniform permeability.
- the named thickness of the Non-woven layer increases the overall thickness of the paper machine screen by a manageable amount Area.
- a uniform permeability of the nonwoven layer also enables a uniform Dewatering the fiber suspension and thus a largely homogeneous consistency of the Press section of the paper machine guided fibers.
- the nonwoven layer consists of plastic melt fibers, such as polyethylene terephthalate, polyamide, polyethylene, polypropylene, Polybutylene terephthalate and combinations of the materials mentioned.
- plastic melt fibers such as polyethylene terephthalate, polyamide, polyethylene, polypropylene, Polybutylene terephthalate and combinations of the materials mentioned.
- the surface of the Vils layer is advantageously permanently topographical, preferably through circular, triangular, rectangular or other recesses, or hydrophilic with the help of physical / chemical surface treatment processes, Designed or designed to be hydrophobic or antistatic or dirt-repellent.
- the chosen Topographies can be made regardless of the structure of the fabric, as requested by the paper manufacturer made by simply designing the surface of the nonwoven layer on the paper become. As such, it is possible to have certain patterns on paper regardless of the To provide the structure of the fabric by appropriate formation of the nonwoven layer. Thereby the structure of the paper can be designed in almost any way.
- the fleece layer is penetrated by pores, whereby the pores can taper or widen towards the fabric.
- the pore size or a pore size range is in particular the retention capacity of the entire paper machine screen as well as the drainage characteristics in three dimensions Regarding the size of the fibers that are to be retained customizable.
- the textile or non-textile fabric on one side faces the paper oriented side fibers or threads that are able to make a permanent with the nonwoven layer
- the fibers or threads preferably made of plastic melt fibers, such as. Polyethylene terephthalate, polyamide, polyethylene, polypropylene, polybutylene terephthalate as well as combinations of the materials mentioned. So that can at least part of the fibers or threads of the fabric and the material from which the Fleece layer is formed, be identical and thus easily a permanent connection with each other come in.
- the nonwoven layer is formed by a connecting means, preferably a hot melt adhesive, fixed on the fabric.
- a connecting means preferably a hot melt adhesive
- the Non-woven layer through a heat / pressure treatment a permanent bond with the fabric come in, depending on the materials chosen, the temperature is approximately between 170 and 270 ° C and the line pressure is approximately between 10 and 50 N / mm.
- the fleece layer is permanently on the ultrasound textile fabrics fixed, the welding frequency between about 15 and 72 MHz, preferably between 15 and 35 MHz. The advantage of the mentioned methods is in that the materials partially dissolve into each other and thus a close connection is brought about between the fleece layer and the textile or non-textile fabric.
- the advantage of the above-mentioned ultrasonic method is that only the the immediate weld is heated, but the area around the weld remains cold.
- the nonwoven layer can be applied selectively to the surface of the fabric and with it this connectable. Unwanted thermal deformations or thermal decomposition due to a too high temperature occur less easily and are on certain areas limited.
- the coverage ratio between the Fleece layer and the paper-facing side of the fabric more than 40%. This enables slower and therefore gentler dewatering of the fiber suspension than in In the case of a less covered surface of the textile or non-textile fabric.
- Fig. 1 is a schematic longitudinal section, also called a weft section through part of a Paper machine screen 15 shown for the wet end of a paper machine, not shown.
- the paper machine screen 15 has a textile or non-textile fabric 16 in the form of a Fabric from an upper layer facing the paper (not shown) from Weft threads 1, 3, 5, 7, 9, 11 and 13 and from a lower one facing the paper machine Location of wefts 2, 4, 6, 8, 10, 12 and 14. It should be noted that the Fabric can be woven or non-woven in nature and therefore only as an example Tissue is formed.
- the fabric 16 has a series of warp threads 17 only of which in FIGS. 1 and 2 a warp thread connecting the upper layer of weft threads and the lower layer of weft threads is shown.
- the warp thread 17 shown extends depending on the Binding phase partly above the wefts 1 and 3 of the upper layer, partly between the Weft threads of the upper layer and the lower layer, between the weft threads 5 and 6, 7 and 8, 9 and 10, partially below at least one weft thread of the lower layer, in selected embodiment below the weft thread 12, and partly again between the layers of the weft threads, namely between the weft thread 13 of the upper layer and the Weft 14 of the lower layer.
- One side 18 with the wefts of the upper layer of the as Fabric formed sheet is to paper, the opposite, other side 19, that is, the lower layer of the weft threads is directed towards the paper machine, not shown.
- the basic structure is any one or more layers Structure, in particular fabric structure, can be used.
- a nonwoven layer 20 is provided on one upper side 18 of the fabric, which this one side of the fabric at least essentially or at least almost completely covered.
- the upper side 18 is completely covered by the nonwoven layer
- the nonwoven layer can also be generally referred to as a non-woven structure.
- the paper-contacting layer formed by the fleece layer 20, which is the aqueous fiber suspension preferably has a fiber-bearing and drainage function.
- the formed by the fabric 16, directed towards the paper machine and with the paper machine in Contacting position represents the wear volume of the sieve and also supports the Drainage of the fleece.
- the fabric 16 forms, as it were, the force-absorbing position of the paper machine screen 15, it runs over standing or moving elements of the not shown Paper machine and protects the nonwoven layer 20 from direct contact with the Paper machine and therefore from wear.
- the fleece layer 20 is permanently compressed and has a thickness of preferably 0.1 to 1 mm and a substantially uniform permeability from FIGS. 1 and 2 can be seen that in the illustrated embodiments, the fibers of the Fleece layer in the area of the weft threads 5, 7, 9, 11 and 13 of the upper layer of the fabric 16 are less compressed than in the area above the warp thread 17 and the weft threads 1 and 3 the top layer. It is clear that in practice the warp thread 17 is closer to the weft threads 1 and 3 of the upper layer and, if at all, only insignificantly above that of the Weft threads 5, 7, 9, 11 and 13 of the upper layer formed level protrudes. It will also go on noted that the illustrations of FIGS. 1 and 2 are simplified schematically and not necessarily are drawn to scale.
- the surface of the textile or non-textile fabric is in different levels.
- the fleece layer ultimately balances these different levels the mentioned different compression, so that the surface of the fleece layer completely is smooth and even.
- the fleece layer is therefore less strong in the areas compressed, in which corresponding areas of the surface of the side facing the paper 18 of the fabric in a predominantly forming the surface of the fabric Level.
- the fleece layer is compressed more in the areas in which individual Threads, in FIGS. 1 and 2 of the warp thread 17, protrude this plane. This is in FIGS. 1 and 2 in the area above the weft threads 1 and 3 the case.
- the aforementioned permanent compression of the nonwoven layer can take place, for example, by that this one with a calender between two counter-rotating rollers Temperature of 170 to 270 ° C and a line pressure of about 10 to 50 N / mm is exposed.
- Temperature 170 to 270 ° C and a line pressure of about 10 to 50 N / mm is exposed.
- the temperature and pressure ranges mentioned depend on the materials used.
- the fleece layer 20 preferably consists of plastic melt fibers, such as polyethylene terephthalate, Polyamide, polyethylene, polypropylene, polybutylene terephthalate and combinations of the materials mentioned.
- the surface 21 of the nonwoven layer 20 is according to the first embodiment shown in Fig. 1 as a smooth plane and according to the second, in Fig. 2 shown embodiment additionally permanently topographically in the form of a line structure or designed in the form of square depressions.
- This design can also be circular, triangular or rectangular or generally polygonal depressions or other shapes (not shown).
- the choice of topographical structure is adapted to the purpose.
- the aforementioned circular depressions can have a diameter of, for example Have 0.1 to 3.5 mm.
- recesses in the form of isosceles triangles a leg length of 0.1 to 3.5 mm. Even the outside lengths with rectangular, in particular square, shape can be 0.1 to 3.5 mm.
- the wells mentioned can Have a length of up to 80% of the total thickness of the fleece layer.
- the nonwoven layer is penetrated by pores. These can extend completely through the entire fleece layer and taper or widen toward tissue 16, for example.
- the surface 21 of the fleece layer 20 with the help of physical / chemical surface treatment processes hydrophilic, hydrophobic, antistatic or dirt-repellent. This can be done, for example, by application suitable chemicals in the form of foam or using immersion processes become. It is clear that the surface charge potential of the nonwoven layer with that of Fiber suspension must be coordinated.
- the fabric 16 has one side 18, which is directed towards the paper, threads that are able to with the Fleece layer 20 to enter into a permanent connection. This is exemplified in FIG Weft threads 5 and 11 of the upper layer are shown, which are permanent in their upper region 22 Connection with the nonwoven layer 20 have been received.
- Such threads can be monofilament, multifilament, coated or so-called sheath core (Two-component) threads made of polyethylene terephthalate, polyamide of types 6.0, 6.6, 6.10, 6.12, polyethylene, polypropylene, polybutylene terephthalate and combinations of the above Materials exist or be made.
- sheath core Tewo-component threads made of polyethylene terephthalate, polyamide of types 6.0, 6.6, 6.10, 6.12, polyethylene, polypropylene, polybutylene terephthalate and combinations of the above Materials exist or be made.
- the fleece layer 20 preferably covers the entire surface of the fabric 16, so that a A new, continuous plane with a possibly structured, permeable surface 21 is created It is also important that the nonwoven layer 20 coincides with the surface of the underlying one Connects tissue and covers the structure of the tissue, so that ultimately the topography of the Fleece layer of the fiber suspension to be dewatered directly.
- the new one Surface 21 of the nonwoven layer and the permeability of the entire paper machine screen 15 can, for example, about the fiber orientation of the fleece layer and the structure control them.
- the nonwoven layer 20 can be applied to the fabric by means of different methods and be connected to it.
- a connecting medium for example a Hot melt adhesive to fix on the fabric 16.
- a connecting medium for example a Hot melt adhesive
- This can take the form of, for example Melt fibers of existing connecting fleece, in the form of a connecting, meltable lattice structure or also in the form of an applied layer of hot melt adhesive, where the connecting means or connecting medium, for example made of polyethylene terephthalate, Polyamide, polyethylene, polypropylene, polybutylene terephthalate or combinations of the above Materials can exist.
- the nonwoven layer 20 is permanent by heat / pressure treatment Bond with the fabric 16 is received, depending on the materials selected Temperature about between 170 and 270 ° C and the line pressure about between 10 and 50 N / mm and the time period is selected such that the fleece layer melts as well the top layer of the fabric is reached. It is clear that the temperatures chosen in the Range of melting points of the materials used are. It also makes sense for the Nonwoven layer material used to the material of the layer contacting the nonwoven layer Fabric 16, especially as far as the respective melting points are concerned. Here it can Fabrics made of polyethylene terephthalate / polypropylene, for example, and the nonwoven layer, for example are made of polypropylene. It is also possible that the surface of the screen fabric Bicomponent fibers or sheath-core fibers exist.
- the fleece layer 20 is also possible to permanently fix the fleece layer 20 to the fabric 16 by means of ultrasound, the welding frequency being approximately between 15 and 72 MHz, preferably between 15 and 35 MHz, preferably 27.12 MHz when processing polyester.
- the fiber orientation within the fleece layer can be varied within wide limits. It can be one targeted fiber orientation or a so-called randomly distributed random fleece for use come.
- the nonwoven layer 20 can also be spray-bonded onto the fabric.
- the coverage ratio between the nonwoven layer 20 and that of the paper directed side 18 of the fabric 16 more than 40 in the embodiments shown % is; the rate of drainage due to the coverage ratio is adjustable. The higher the coverage ratio, the slower and therefore more gentle the fiber suspension is drained.
- the topographic The tendency of the screen to mark is reduced to a minimum. Furthermore, the retention values of the sieve improved during paper production.
