Definitions
- the present invention relates to a tape for producing sheet material, such as. B. spunbonded web.
- EP 1 448 820 B1 discloses a machine for producing spunbonded nonwoven webs which, as a forming and transporting belt, displays a fabric belt with a so-called 4B weave pattern, there called "4B Weave”.
- Such fabric tapes often have, especially for use as forming and conveyor belts of spunbonded nonwoven webs, very high height differences between the provided by Kröpfitch the longitudinal threads and by Kröpfitch the transverse threads parts of the web material contact side.
- spunbonded nonwoven webs formed and subsequently transported thereon which generally have very low basis weights per layer of less than 20 grams / m 2 , are capable of machine speeds often used in such processes of up to 1100 meters per meter Minute example. Can not be reliably transported due to air turbulence. If the vacuum level is raised in order to stabilize the transport of the spin nonwoven webs, these spunbonded webs are often drawn into the weave structure, as a result of which they are often difficult to remove from the fabric webs during a subsequent transfer process.
- a fabric tape on the at intended use in a machine for producing spunbonded nonwoven webs such spunbonded webs are formed and transported, comprising a plurality of longitudinally extending substantially in a band longitudinal direction and a plurality of substantially extending in a transverse direction and transverse ligaments with the longitudinal threads transverse threads, the longitudinal and the Cross threads are constructed essentially of a polymer material and a part of the longitudinal and / or transverse threads comprises electrically conductive material, wherein longitudinal threads on the web material contact side form convex longitudinal thread covings with respective vertex and the transverse threads comprise first transverse threads and the first transverse threads on the web material contact side convex first Form cross-threadings
- the height difference between the vertices of at least some, in particular the convex longitudinal thread and the vertices at least some, in particular the first convex Querfadenkröpfitch on BrumaterialKeyseite smaller than 220 ⁇ , preferably less than 180 ⁇ , more preferably less than 150 ⁇ ,
- the spunbond filaments Due to the fact that the difference in height between the vertices of convex longitudinal thread coving and first transverse thread creases running on the web material contact side is less than 220 ⁇ , preferably less than 180 ⁇ , more preferably less than 150 ⁇ , the spunbond filaments have a very uniform support in terms of height when they are deposited on the web material contact side of the fabric belt and therefore do not dip so deeply into the fabric structure as is the case with the prior art fabric tapes. This means that the spunbonded nonwoven web formed from the spunbonded filaments experiences a high contact surface with less immersion of the spunbonded filaments into the fabric structure.
- this fabric structure ensures that soiling, for example in the form of polymer drops, which can fall from the spun-thread extrusion nozzles onto the fabric tape, does not fall so deeply into the fabric structure.
- the fabric tapes according to the invention do not pollute so much and are easier to clean.
- the height difference between the vertices of the convex longitudinal thread counts and those of the first cross thread counts is determined in a section plane perpendicular to the web material contact side.

- a sample of the tissue band to be measured with a diameter of 10 millimeters in a pressure chamber is placed flat in a sandwich between two Plexiglas plates under a pressure of 0.1 MPa. The measurement was carried out with a resolution of 8 micrometers.
- vertex of the convex thread turn is to be understood as the highest point of the considered thread turn at the web material contact side.
- the tape longitudinal direction coincide with the transport direction or tape movement direction or machine direction.
- transport direction or tape movement direction or machine direction are to be regarded as synonymous.
- the solution according to the invention can be realized, for example, by providing that the polymer material of the longitudinal threads and the polymer material of the first transverse threads is selected and the fabric tape is heat-set so that the first transverse threads are deformed more than their state prior to heat-setting the longitudinal threads against their condition were deformed before the heat fixing.
- the longitudinal threads were subjected to tensile stress, while the longitudinal and transverse threads were exposed to a temperature of at least 150 ° C., preferably in the range from 180 to 200 ° C.
- the polymeric material of the first transverse filaments may be constructed with a two-phase polymeric material, wherein a first polymeric material phase of the two-phase polymeric material has a higher melting temperature than a second polymeric material phase of the two-phase polymeric material, and wherein the longitudinal filaments have a Polymer material, in particular with a single-phase polymer material, constructed and the polymer material of the longitudinal threads having a melting temperature above the second polymer material phase melting temperature.
