Definitions
- the machine speed could be greatly increased with the result being the search for materials with a strong speed increase has increased after the installation of a new paper machine fabric.
- the invention relates to new (base) fabrics for papermaking machine felts, in particular Press felts with improved properties, in particular with improved elasticity in Direction of felt thickness, higher compressibility and improved Water absorbency during paper production from beginning to end the duration of the felts.
- the object of the invention is achieved in that in the manufacture of the Support fabric for the paper machine felt in warp and / or weft direction Combination action of polyamide and thermoplastic polyurethane filaments, especially twisted yarns of combination twists having 1 to 20 monofilaments of polyamide 6 and / or polyamide 4.6, polyamide 6.10, polyamide 6.12, polyamide 11 or polyamide 12 and 20 to 1 monofilaments made from thermoplastic Polyurethane can be used instead of twist or single monofilament yarns, which are composed solely of polyamide monofilaments.
- the textbook of paper and board production (Textbook of Paper and Paperboard Production, VEB-Fachbuchverlag 1987, page 190 ff.) Contains information about the Papermaking in modern papermaking machines, e.g. regarding leaf formation (forming section), the mechanical dewatering (press section) and the thermal Dehydration (drying section) further the smoothing (calendering) and winding.
- Fabrics for the sheet forming section are mainly made of polyester monofilaments. To increase the abrasion resistance, monofilaments are on Base of polyamide monofilaments together with polyester filaments as alternating Threads used in the transverse direction to the machine run of the paper machine.
- Press felts in the press section consist of one or more non-woven fabrics needled basic tissues. These press felts are almost exclusively made Polyamide fibers and polyamide monofilaments produced, mainly from pure Polyamide 6 or polyamide 6.6 filaments.
- Fabric for the drying section used in the last part of the paper machine are usually made of polyester monofilaments that are resistant to hydrolytic Degradation are stabilized, e.g. by stabilizers such as Stabaxol® (commercial Product, manufactured by Rheinchemie, Mannheim).
- stabilizers such as Stabaxol® (commercial Product, manufactured by Rheinchemie, Mannheim).
- Patent US-A-4,323,622 discloses a highly elastic dewatering felt for use, for example, in papermaking or in cellulose machines, in which the elastic properties of the felt by an admixture of molecular thermoplastic elastomers is achieved.
- the Elasticity aligned in the machine direction, and the elastomer material is intended in be able to stretch to at least twice its original length and Finally, quickly substantial to reduce the original length, after the Load is taken from the tissue.
- the patent US-A-4 533 594 discloses a paper machine felt in which the Mesh layer is a fabric, which in turn is formed from yarn in the machine direction in connection with yarn in the cross machine direction.
- the Cross-directional yarns are multifilament yarns based on nylon, Polyester or polyacrylonitrile with a polyurethane coating.
- This patent has set itself the task of a paper machine felt of the batt-on-mesh type to provide, in which the mesh has improved clamping force.
- One Similar fabric is described in the patent US-A 4,731,281. Herein a fabric of fully encapsulated monofilament yarns is obtained.
- the Yarns are coated before weaving to give the fabric non-stick properties to rent. The coating can be adjusted so that the thickness of the yarn in Machine direction is different than the thickness of the yarn in the cross machine direction.
- the coating on the monofilaments consists of another type of polymer and is only physically around the core filament bound.
- the coating is only very weakly chemically bonded. That means, that the coating can be deformed or moved on the core filament, the originally desired properties therefore decrease.
- the needling process during the production of the paper machine felt is typically very aggressive in Regarding this type of coating, which in turn means that the originally desired properties are not preserved.
- the coating on the core yarn only part of the cross section in the Yarn. The actual elastic deformation therefore occurs only in a small part the shell instead, resulting in a low elastic effect.
- the tensile / relaxation property of a fabric based on this type of yarn thus almost depends only from the properties of the core material.
- Another press fabric with coated yarn in the press section of a Paper machine can be used in the patent US-A 5 360 518 described. It has a multi-layered structure with a thin one paper-contacting surface and a wide substructure.
- One of two or more Layers of woven yarns include multicomponent yarns having a plurality of weight-bearing strands.
- the multicomponent yarns may be multifilaments or Multi-strand game, which are composed of thin polyamide filaments. They can also be and impart polyurethane coated monofilament yarns the press fabric a compressible structure with resilience.
- the multifilament or Multi strand yarns may also be polyurethane coated.
- a paper machine felt is described by It is claimed that it has excellent elasticity over a long period of time comprises, and consists of a base fabric and needle-punched nonwoven layer and a separate Film layer with furrows, their orientation in the transverse direction to the machine direction to have.
- a film may be in the base tissue or between different Layers of the felt be provided.
- the paper machine felt is then in able to pass smoothly through the wrapping part of the paper machine and is comparatively resistant to fatigue due to the repeated Pressing in the press nip can be done.
- the lamination of the elastic layers can be very risky on a solid base tissue. Behavior and bumps can be easy be generated. The edges of the film must be connected, these areas always not perfect areas.
- TPU monofilaments and / or twisted Use yarns based on TPU monofilaments in the base fabric of press felts The expert would probably first serious processing problems expect since monofilaments based on thermoplastic polyurethanes highly elastic and are highly elastic and also a high coefficient of friction exhibit. TPU monofilaments are therefore only larger diameter and processed under tension. Yarns and fabrics made this way defects would be unacceptable to the papermaking industry are. The dimensional stability and tension in paper machine running direction and Transverse to the paper machine direction would not be tolerated. Because the elastic yarns are highly elastic, such a fabric would be a lower modulus in the machine direction and a high contraction in the transverse direction to Have machine direction.

- a base fabric which is characterized in that the Monofilaments in the combination yarn (polyamide and / or TPU monofilaments) have a diameter in the range of 0.05 to 2 mm.
- a particular advantage of the above-mentioned base fabric is that for its production including the existing paper machine manufacturing technology without further ado Conventional twisting machines and weaving machines can be used.
- Another advantage is that the elastic modulus of the polyamide in the machine direction is maintained and with the modulus of elasticity of the thermoplastic polyurethane can be combined in the direction of the thickness of the fabric.
- press felts based on the invention Base fabric, not just a larger paper dewatering capacity but also reach a higher drainage level faster and their Maintain drainage capacity for a longer period than press felts, made without the above-mentioned combination yarns based on TPU polyamide were. It was also found that the paper machine vibrations can be reduced further, if press felts are used, which with the help of above base fabric were made.
