Definitions
- the invention relates to a paper machine clothing, in particular a press felt, with a carrier and with threads, which as profiled monofilaments with one by one circular cross-section deviating profile are, with profiled monofilaments are present that are helically profiled.
- Paper machine clothing is circulating in paper machines Tapes of great length and width, that of training and guiding the paper web through the paper machine serve. Their structure depends heavily on what part the paper machine they are used. In the first two sections of a paper machine, the sheet forming section and the press section, the paper machine clothing be designed so that the paper web as possible is well drained so that the energy expenditure for thermal drying in the subsequent dryer section remains low. The drainage happens through the paper machine clothing, i.e. she must be so constructed that the one coming from the paper web Liquid as efficiently as possible to the other side of the Paper machine clothing is transported.
- the threads that make up the textile backing have in usually a circular cross section.
- For certain Purposes are also rectangular, flat threads in cross section used.
- there are a number of suggestions for other cross-sectional shapes of threads for the Carriers of paper machine clothing or the fibers of non-woven pads, some of which are highly profiled are (DE-A-40 31 608; US-A-5,361,808; DE-A-195 45 386; US-A-5,591,525; EP-A-1 067 239; DE-A-199 00 989; EP-A-0 995 835).
- the profiling of these threads or fibers from a wide variety Establish. Common to all threads or fibers is that Profile is elongated, i.e. in the axis of the extends each thread.
- GB-A-1 053 282 and US-A-3,158,984 proposed profiled monofilaments to use different cross-sectional shapes which are twisted helically so that there is a helical profiling results.
- the Monofilaments twisted independently of each other around their longitudinal axis and fixed in this state within the carrier.
- the invention has for its object a paper machine clothing of the type mentioned at the outset, that good drainage properties at easier Manufacturing can be achieved.
- This object is achieved in that the helical profile of the profiled monofilament has already been imprinted during their manufacture and therefore free of torsional stress in the paper machine clothing available.
- Basic idea of the invention So it is to use monofilament for the wearer helical profiling during manufacture, for example in the case of extrusion by appropriate Nozzle shapes or during subsequent stretching has been so that the monofilaments in the carrier are tension-free available.
- Such monofilaments can be the helical profile very precisely produce. Due to the torsion-free condition do not change their shape in the company. It will So even and good drainage properties over the surface achieved, the manufacture of the Carrier with the preformed monofilaments in the usual way can happen. The individual twist required in the prior art the monofilament is eliminated.
- helically profiled monofilaments can also influence the pore volume and thus the Drainage capacity can be taken. Conveniently, should be at least 30% of the lengthways and / or in Transversely extending threads profiled helically Be monofilament, with all longitudinal and / or Cross threads such monofilaments can be.
- a thread made of a material, in particular polyvinyl alcohol form that in a solvent, preferably Water, is soluble, in which the helically profiled Monofilament and the spun yarn not soluble are.
- This soluble thread can be introduced into the paper machine clothing through a treatment with be dissolved out of the solvent, whereby an additional free volume in the paper machine clothing is formed.
- pore volumes is generally known (see US-A-4,482,601; EP-B-0 466 990; EP-B-0 413 869; EP-A-0 565 206; WO 98/07925).
- the threads should from the soluble material like this with the helical profiled monofilaments that they are spacers form between adjacent threads.
- the helically profiled monofilaments do not have to Parts of the carrier of the paper machine clothing, but can also be outside of the carrier, for example run as filler threads or the like. Conveniently, but at the same time they form parts of the carrier, the carrier also being made entirely of such monofilaments can exist.
- the carrier can be any type of thread structure be, for example a woven fabric, knitted fabric, scrim and / or Yarn sheet.
- Network carriers can also be provided as carriers be with the helically profiled monofilaments are combined.
- the carrier can be single layer or be constructed in multiple layers or also from several, carrier webs not interconnected by threads consist of either the same training or are also different.
- the carrier can be made from a Woven, knitted and / or a network can be formed and additionally have a scrim or a group of threads.
- the support is embedded in a fiber matrix by for example between at least two fiber layers is included, which are needled together.
- the material of the helically profiled monofilament and possibly the staple fiber yarns can the usual materials for paper machine clothing be used. These are especially thermoplastic Polymers. Examples are 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 also be used become.
- the monofilament 1 shown in FIGS. 1 and 2 has one rotationally symmetrical cross section with a core 2 and a total of six webs projecting radially outwards - designated by way of example with 3 - which at their ends are spherically widened.
- the webs 3 close between deep indentations - exemplified with 4 - a, which form grooves in the monofilament 1 over the length.
- the profile of the monofilament 1 designed helically, so from its outer design twisted here in itself, so that the webs 3 and also the grooves formed by the egg arches 4 are helical run around the core 2 of the monofilament 1.
- a monofilament 13 according to the invention is disclosed in FIG. that is only mirror symmetric. It has two opposite domes 14, 15 on both sides run out in thickenings 16, 17 of different shapes.
- Figure 8 is a helically profiled monofilament 18, which is rotationally symmetrical and four bulges 19, 20 distributed over the circumference, 21, 22, the bulges 19, 20, 21, 22nd are connected via convex areas. This too There are groove-shaped depressions in the profile.
- Figures 9 to 11 are more helically profiled Monofilaments 23, 24, 25 shown in cross section, with a regular pentagon (Figure 9), one Square ( Figure 10) and a triangle ( Figure 11). Also when connecting the corners or edges of these monofilaments 23, 24, 25 form straight lines, result from the helical Profile pore volumes and drainage channels.
