A triple papermaking fabric comprises: a set of top MD yarns; a set of top CMD yarns interwoven with the top MD yarns; a set of bottom MD yarns; a set of bottom CMD yarns interwoven with the bottom MD yarns; a set of binding yarns arranged in pairs between respective top CMD yarns; the binding yarns of each pair are interwoven with respective different top MD yarns, and the binding yarns, together, of the pair are interwoven with all the top MD yarns; the binding yarns are arranged in pairs between respective consecutive top CMD yarns; the binding yarns of each pair bind respective different bottom MD yarns, each binding yarn of the pair binding only one bottom MD yarn.

A method for manufacturing a deflection member is disclosed. The method may include the steps of providing an additive manufacturing apparatus that includes at least one radiation source and a vat containing a photopolymer resin, providing a reinforcing member, contacting a surface of the reinforcing member with the photopolymer resin, and directing radiation from the at least one radiation source towards a surface of the reinforcing member to at least partially cure photopolymer resin in contact with the surface of the reinforcing member to create at least a portion of a lock-on layer.

A method for manufacturing a deflection member is disclosed. The method may include the step of incorporating a monomer, a photoinitiator system, a photoinhibitor, and/or a reinforcing member. A further step includes blending the monomer, photoinitiator, and/or photoinhibitor to form a blended photopolymer resin. Further steps may be emitting a first wavelength and emitting a second wavelength. A further step may be polymerizing the monomer to form a resinous framework comprising protuberance locked-on to the reinforcing member.

A process for fibrillating a fibrous pulp, and products made using the same. The process comprises providing a fibrous pulp of liquid and staple fibers having a first liquid to fibers ratio of less than or equal to 6:1, applying stress to the pulp to fibrillate the staple fibers; and, during said applying stress, drying the pulp to a second liquid to staple fibers ratio of less than or equal to 0.43:1.

A paper machine clothing has a plurality of through-channels formed in a usable region. The through-channels extend through the substrate to connect the upper and lower sides. The through-channels are non-cylindrical with a cross-sectional area becoming smaller along a thickness direction of the substrate from the upper side to a middle region of the substrate. An upper rim of at least one of the plurality of through-channels directly contacts an upper rim of at least one other neighboring through-channel of the plurality of through-channels, wherein the upper rims of both neighboring through-channels have at least three common local maxima, including two outer common local maxima and one intermediate common local maximum that is located between the two outer common local maxima. There is also described a method of producing such a paper machine clothing.

A wet laid process includes a method for making paper in which a composition containing co-refined cellulose fibers and cellulose ester fibers made into a thick stock composition in a machine chest, the thick stock is fed to a cleaning/screening zone through a device that regulates the flow rate of thick stock, the consistency of the thick stock fed to the screening/cleaning zone is reduced to form a thin stock composition; the thin stock composition is subjected to a process for cleaning the thin stock and feeding the cleaned thin stock through screens to form a cleaned and screened thin stock composition, and the cleaned and screened thin stock composition is fed to a headbox.

A dryer fabric has a weft of cross machine direction yarns (6) and a first warp of first machine direction yarns (5) and a second warp of second machine direction yarns (9). The yarns of the first warp are arranged above the yarns of the second warp on a first surface (FS) side. The first warp has primary yarns (51) of PPS or PK yarns whose breaking load remains substantially stable within 15 days in conditions where RH=100%, T=125° C. and p=2.3 bar; and secondary yarns (52) of PET with breaking loads which substantially decrease under the same conditions. At least every second yarn of the first warp is a secondary yarn (52). The secondary yarns (52) may be two out of three or three out of four of the first machine direction yarns (5). PET reduces cost and adds elasticity to the dryer fabric.

The invention relates to a clothing (10) for a machine to manufacture or refine a fibrous web, in particular a paper, cardboard, or tissue web, comprising a substrate (40) and a grid structure (20) applied on the substrate (40), on which the fibrous web is transported when the clothing (10) is used as intended, wherein the grid structure (20′) comprises a plurality of first elements (24′), all of which aligned in a first direction, and a plurality of second elements (26′), all of which aligned in a second direction, which is different from the first direction, wherein the first elements (24′) penetrate the second elements (26′), forming the grid structure (20′), such that an underside of the first elements (24′) facing the substrate (40) and an underside of the second elements (26′) facing the substrate (40) are located in a common plane. In addition, the present invention relates to a method for producing such a clothing.

An industrial textile (6) for manufacturing a fibrous web has first machine direction yarns (1) on the front side (7) which bind to first cross-machine direction yarns (4) in a first pattern, while second machine direction yarns (2) on the back side bind to second cross-machine direction yarns (5) in a second pattern. Third machine direction yarns (3) bind to the first cross-machine direction yarns (4) and the second cross-machine direction yarns (5) in a third pattern. The third pattern has at least one interlacing point (71) on the front side where one of the third machine direction yarns (3) passes over one of the first cross-machine direction yarns (4) and at least one interlacing point (72) on the back side (8) where the same third machine direction yarn (3) passes under one of the second cross-machine direction yarns (5).
