Definitions
- the invention relates to a paper machine clothing, in particular a press felt, with a carrier, at least a layer of a yarn layer with parallel to each other having running yarn threads.
- the invention relates to further a method for producing a paper machine clothing.
- Paper machine clothing is circulating in paper machines Bands of great length and breadth, of training and Guiding the paper web to serve through the paper machine. you Construction depends heavily on which part of the paper machine they are used.
- Pressed felts are common in which a carrier embedded in a fiber matrix.
- the carrier serves the inclusion of particular acting on the press felt Tensile forces and is designed primarily as a tissue, wherein the carrier also consists of several, not among themselves connected carrier webs can be constructed. On this The carrier is then needled on one or both sides of a fiber fleece, that for a protection of the wearer from abrasion and ensures even surfaces.
- Such generic press felts are for example the EP-B-0 394 293 and EP-A-0 038 276.
- the Thread scrims are characterized by the fact that they are made of a Variety parallel to each other running jelly threads, wherein the jelly threads in both longitudinal and can also extend in the transverse direction. Such scrim can also be used with other thread structures, such as Tissues, are combined (see DE-C-40 40 861).
- the jelly threads must be spaced apart exhibit. These distances should be as equal as possible and be consistent over the extent of the jelly threads, so that the drainage properties of the press felt over whose surface is even. In the production of such However, there are problems for press felts for such same and consistent distances, in particular during the needling process for connection and Solidification of the fiber fleece layers.
- WO 99/64670 proposes the jelly threads at the crossing points by means of melted, water-soluble polymer material to connect and the polymer material after completion of the Wash out paper machine clothing.
- the polymer material requires an additional process step.
- GB-A-1 536 231 and US-A-3,358,911 is proposed instead determine the jelly threads for the manufacturing process by that they are first in a tissue with transverse to the Jelly threads running, water-soluble threads involved then, after completion of the paper machine clothing be removed.
- the invention is based on the object, a paper machine clothing of the type mentioned above in such a way that over its surface as uniform as possible drainage properties be achieved. Another task is to provide a method for producing a to provide such papermachine clothing.
- the first object is achieved according to the invention by that spacer threads are present between two Gel threads run and soluble in a solvent are in which the rest of the paper machine clothing is not soluble.
- Basic idea of the invention So it is, between the jelly threads - and preferably between all jelly threads - provide spacer threads, the jelly threads on a predetermined and over their extension keep a constant distance. she stabilize thereby the position of the jelly threads and provide for their even distribution across the surface.
- There they are introduced with the production of the carrier, it comes in subsequent manufacturing steps, in particular when embedding the carrier in a fiber matrix for example by needling fiber webs, not to dislocations of the jelly threads, i. their distribution remains until the completion of the papermachine clothing receive. Only then are the spacer threads dissolved out to the desired water permeability to obtain.
- the release can be before feeding into the paper machine done by a corresponding washing step or only after feeding, wherein the dissolving through the liquid squeezed out of the paper web takes place during a break-in phase.
- the spacer threads are water-soluble, in particular filaments of polyvinyl alcohol to offer.
- the spacer threads run parallel to the jelly threads, i.e. the jelly threads and the spacer threads are located Side by side, it being understood that the spacer threads remain the same over their extent Have cross-section.
- a spacer thread is sufficient between two jelly threads, so that always alternate a jagged thread with a spacer thread.
- the spacer threads each wrapped around a gel thread or so are twisted with this so that they are outside protrude.
- jelly threads are provided with outwardly projecting fibers, wherein the fibers are preferably predominantly perpendicular to Surface of the jelly threads - but also at an angle up to 60 ° from vertical - should stick out.
- Such Jelly threads can be those wrapped with spun yarns Jelly threads, as known from EP-B-0 394 293, at least partially, but preferably completely replace, where not all jelly threads are formed in the way must be, but they are expediently.
- the advantage of such jelly threads is that such Gelegefäden much easier and therefore cheaper make, for example by sticking the Fibers and in particular flocking or by training as chenille threads.
- the protruding fibers can not only by flocking, but also by roughening, in particular Scraping the material of the monofilaments are generated.
- seam felts Jelly base can be made because the monofilaments to form loops at the end edges of the papermachine fabric suitable and over which these ends by means of a pushed through the loops pigtail can be connected.
- Such seam felts are in particular in the press section a paper machine essential Easier to move in than endlessly manufactured press felts.
- the jelly threads with outwardly projecting fibers as twines from monofilaments, preferably from two to twelve monofilaments Individual threads, each with a diameter of 0.1 to 0.4 mm, or as multifilaments. These too Threads can be flocked. Instead, there is the Possibility of the outward standing fibers between the Pinch individual threads.
- a part or all jelly threads profiled as a helical Monofilaments are formed. So you do not have one round cross-section, in which the profile is longitudinal the monofilament seen helical or helical runs, the respective monofilament so in terms of his outer design twisted around its longitudinal axis is.
- Jelly threads will open the volume inside the paper machine clothing increased, and there are better drainage properties. This effect can by the number, training and arrangement of these jelly threads varied to a considerable extent and thus to the respective Requirements are adjusted. It happens not on whether the jelly threads within the papermachine clothing under torsional stress, they stand so twisted only after their preparation and in this Condition has been introduced into the paper machine clothing are or whether the helical profiling is already in the production, for example in the extrusion by appropriate nozzle shapes or the subsequent Stretching, has been imprinted and therefore the monofilaments without tension in the papermachine fabric.
- the cross sections of the helical profiled monofilaments have great freedom. So they can an oval, trilobal, polygonal, square, rectangular, clover-shaped and / or have triangular cross section, with the cross sections not even need to be regular or symmetrical. It is also possible to use monofilaments of different cross sections be present according to the requirements Influence on the pore volume and thus on the drainage properties to take. A particularly high one Pore volume results when profiled helically Monofilaments are present whose cross section over the Circumference distributed having several indentations. Vice versa but can also be distributed over the circumference bulges provided or both combined together in the way be that in and bulges over the circumference alternate. It can also be helical extending sharp or rounded edges provided be.
- helically profiled monofilaments can also influence the pore volume and thus the Drainage be taken.
- the carrier can be single or multi-layered be formed or from several, with each other carrier webs not connected by threads, which are either the same or different are.
- the carrier may also be a woven, knitted fabric and / or have a network, as long as a location from scrim is available.
- the carrier is embedded in a fiber matrix, in he, for example, between at least two fiber layers is included, which are needled together.
- the material of the jelly threads can be used for paper machine clothing usual materials used become. These are in particular thermoplastic polymers, for example, polypropylene, polyamide 4.6, polyamide 6, polyamide 6.6, polyamide 6.10, polyamide 6.12, polyamide 11, polyamide 12, PET, PTT, PBT, PPS, PEK or PEEK. Also elastomeric polyesters are useful.
- the press felt 1 shown in Figures 1 and 2 has a Carrier 2, which consists of three superimposed layers consists, each formed as a thread scrim 3, 4, 5 are. All three thread scratches 3, 4, 5 are made respectively parallel in the plane of the press felt 1 extending jelly threads - exemplified by 6, 7, 8 -, respectively have the same distance to each other.
- the jelly threads 6, 8 of the upper and lower Fadengelege 3, 5 run while in the longitudinal direction of the press felt 1, the same time whose direction is, while the jelly threads 7 of the mean Fadengeleges 4 extend transversely thereto.
- the Carrier 2 is embedded centrally in a fiber matrix 9, which is shown only in layers in Figure 2 and created by needling fiber webs.
- the press felt 1 is already in its final state, as it is used in the paper machine. characteristic are the distances between the yarn threads 6, 7, 8. These distances were caused by the fact that between the Jelly threads 6, 7, 8 already in the production of the carrier 2 spacer threads have been incorporated, their Clearrekkung in the plane of the respective yarn layer 3, 4, 5 the in Figures 1 and 2 to be recognized, now free distance the Gelegefäden 6, 7, 8 corresponded.
- the carrier 2 is then covered with fiber webs and through a needle machine, in which the fiber webs under Forming the fiber matrix 9 matted together and solidified were.
- the spacer threads have ensured that there are not displacements of the jelly threads 6, 7, 8 has come. Subsequently, the spacer threads by the action of a solvent - with spacer threads Polyvinyl alcohol can use water as a solvent are - have been liberated, causing the free Distances between the Gelegefäden 6, 7, 8 showed.
