Definitions
- the invention relates to a paper machine clothing, in particular a press felt, with a carrier that at least a layer of a scrim with parallel to each other has running scrim threads.
- the invention relates to the further a method for producing a paper machine clothing.
- Paper machine clothing is circulating in paper machines Tapes of great length and width, that of training and Guide the paper web through the paper machine. you Construction depends heavily on what part of the paper machine they are used.
- press felts are common in which a carrier is embedded in a fiber matrix.
- the carrier serves the inclusion, in particular, of those acting on the press felt Tensile forces and is primarily formed as a fabric, wherein the carrier also does not consist of several, among themselves connected carrier webs can be constructed. On this The carrier is then needled on one or both sides of a nonwoven fabric, that protects the wearer from abrasion and ensures flat surfaces.
- laid scrim can also be used for the wearer be provided in single and multi-layer training.
- Such generic press felts are, for example EP-B-0 394 293 and EP-A-0 038 276.
- the Threads are characterized by the fact that they consist of a There are a large number of parallel laying threads, the scrim threads in both longitudinal and can also extend in the transverse direction.
- Such laid scrims can also with other thread structures, such as Woven fabrics can be combined (cf. DE-C-40 40 861).
- the scrim must be spaced apart exhibit. These distances should be as equal as possible and be constant over the extension of the scrim threads, thus the drainage properties of the press felt whose area is even.
- the invention has for its object a paper machine clothing of the type mentioned at the beginning that drainage properties as uniform as possible over their area can be achieved. Another job is a method of making one to provide such paper machine clothing.
- the first-mentioned object is achieved according to the invention by that there are spacer threads between two Laying threads run and are soluble in a solvent in which the remaining part of the paper machine clothing is not soluble.
- Basic idea of the invention So it is between the scrim threads - and preferably between all scrim threads - to provide spacing threads, which the laid threads on a predetermined and over keep their distance at a constant distance. she thereby stabilize the position of the scrim and provide for their even distribution over the surface.
- There they are introduced during the manufacture of the carrier, it occurs in subsequent manufacturing steps, in particular when the carrier is embedded in a fiber matrix for example by needling nonwovens, not to shift the scrim threads, i.e. their distribution remains until the paper machine clothing is completed receive. Only then are the spacer threads detached to the desired water permeability to obtain.
- the spacer threads are water-soluble, in particular threads made of polyvinyl alcohol to offer.
- the result is paper machine clothing with at least one scrim having carrier that extends through the surface very uniform drainage properties.
- the spacer threads run parallel to the scrim threads, i.e. the lay-up threads and the spacer threads lie Side by side with each other, it being understood that the spacer threads are constant over their extension Cross section.
- a spacer thread is usually sufficient between two scrim threads, so that always alternate a scrim with a spacer thread.
- the spacer threads each wound around a scrim or are twisted with this so that they are outside protrude.
- the threads lie against each other, either the spacer threads, when all scrim threads are wrapped with spacer threads or are twisted with them, or from each a spacer thread and a scrim thread, if only everyone second laid thread wrapped by a spacer thread or is twisted with this.
- the point touch can go into line contact when the scrim threads are completely wrapped by the spacer threads and for example are formed as flat threads or tapes.
- scrim threads are wound with a spun yarn or are twisted, as is already the case with paper machine clothing according to EP-B-0 394 293 is.
- scrim threads are provided with fibers that protrude outwards, the fibers preferably predominantly perpendicular to Surface of the scrim threads - but also at an angle should protrude up to 60 ° from the vertical.
- Such Laying threads can be wrapped with spun yarns Scrim threads as known from EP-B-0 394 293 replace at least partially, but preferably completely, whereby not all scrim threads are formed in this way have to be, but they are expedient.
- the advantage of such scrim is that such Plaid threads much easier and therefore cheaper can be produced, for example by gluing the Fibers and in particular flocking or through training as chenille threads.
- a part or all laid threads as helically profiled Monofilaments are formed. So you don't have one round cross-section, with the profile in the longitudinal direction the monofilament seen helical or helical runs, the respective monofilament with regard to its outer design twisted in itself around its longitudinal axis is.
- helically profiled monofilaments can also influence the pore volume and thus the Drainage capacity can be taken.
- the carrier can be single-layer or multi-layer be formed or from several, one below the other there are carrier webs not connected by threads, which are either the same or different are.
- the carrier can also be a woven, knitted fabric and / or have a network, as long as a layer from scrim is present.
- the support is embedded in a fiber matrix, in for example between at least two fiber layers is included, which are needled together.
- a fiber matrix in for example between at least two fiber layers is included, which are needled together.
- the material of the scrim threads can be used for paper machine clothing usual materials used become.
- 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.
- elastomeric polyesters can be used.
- the press felt 1 shown in FIGS. 1 and 2 has one Carrier 2, which consists of three layers one on top of the other exists, each formed as a scrim 3, 4, 5 are. All three scrims 3, 4, 5 each consist of Laying threads running parallel in the plane of the press felt 1 - exemplified with 6, 7, 8 -, each have the same distance from each other.
- the scrim threads 6, 8 of the upper and lower scrims 3, 5 run thereby in the longitudinal direction of the press felt 1, which at the same time whose direction is, while the scrim 7 of middle scrim 4 extend transversely to it.
- the Carrier 2 is embedded in the middle in a fiber matrix 9, which is only shown in layers in FIG. 2 and was created by needling nonwovens.
- the press felt 1 can already be seen in its final state, as it is used in the paper machine. characteristic are the distances between the scrim threads 6, 7, 8. These distances were caused by the fact that between the Laying threads 6, 7, 8 already during the manufacture of the carrier 2 spacer threads have been incorporated, their extension in the plane of the respective scrim 3, 4, 5 the in FIGS. 1 and 2, now clear distance which corresponded to scrim 6, 7, 8.
- the Spacer threads square or rectangular cross-section have had to slide spacer threads on top of each other and to avoid scrim 6, 7, 8.
- the carrier 2 is then covered with non-woven fabrics and by ran a needle machine in which the nonwovens under Formation of the fiber matrix 9 matted and solidified together were.
- the spacer threads have ensured that there is no shifting of the scrim threads 6, 7, 8 has come.
- FIG. 3 shows a laid thread 10 in the side view, which has a monofilament 11, which with essentially Fibers protruding perpendicularly from its surface - exemplary designated with 12 - is flocked.
- FIG. 4 shows a laid scrim 13 with the laid thread 10 according to Figure 3, wherein the scrim 13 of a variety of side by side, parallel to each other extending scrim threads 10, the same distances to each other.
- Figure 5 shows a scrim 14, which consists of a thread 15 with pinched between the individual threads of the thread 15, vertically protruding tufts of fibers - exemplary designated 16 - exists. It is understood that this Tufts of fibers 16 - similar to the laid scrim 13 see - are distributed over the circumference.
- Figure 6 shows a scrim 17, the Chenille thread with a core thread 18 and essentially vertical thereof protruding fibers - designated by way of example at 19 - is trained.
- a fabric thread 21 is shown in FIGS. which is designed as a monofilament and a rotationally symmetrical Cross section with a core 22 and overall six webs projecting radially outwards - exemplary designated 23 - is formed on their Ends are crowned widened.
- the webs 23 close deep indentations between them - exemplary at 24 designated - a, which in the laid thread 21 on the Form length grooves.
- the profile of the scrim is 21 helically shaped, so from its outer Design twisted in itself, so that the webs 23rd and also the grooves formed by the concavities 24 extend helically around the core 22 of the laid thread 21.
- the profile of the scrim is 21 helically shaped, so from its outer Design twisted in itself, so that the webs 23rd and also the grooves formed by the concavities 24 extend helically around the core 22 of the laid thread 21.
