Abstract: An apparatus for making paper. The apparatus comprises a felt and a pattern layer joined to the felt. The felt has a relatively high UV absorbance. Such a high UV absorbance prevents the actinic radiation applied to cure the pattern layer from scattering when the radiation penetrates the surface of the pattern layer. By limiting the scattering of radiation beneath the surface of the pattern layer, extraneous cured pattern layer material is minimized in the regions of the felt where it is desired not to have pattern layer material. 00000

Abstract: Nonwoven material produced by hydroentanglement of a wet-laid or foam-formed fibre web. The material comprises a mixture of short plant fibres, in particular pulp fibres, and long hydrophilic plant fibres, where the major portion of the fibres presents a fibre length which is at least 10 mm, whereby the portion of long fibres is at least 1 wt.% of the fibre weight. The fibres were mixed with each other in the presence of a dispersing agent which allows a uniform fibre formation, in a wet-laid or foam-formed fibre web which has been hydroentangled with sufficient energy to form a compact absorbing material.

Abstract: A belt for through-air drying a cellulosic fibrous structure. The belt comprises two layers, a web contacting first layer and a machine facing second layer. The two layers are joined together by either adjunct tie yarns or integral tie yarns. The resulting belt has a backside texture caused by opaque yarns which shield actinic radiation. The opaque yarns are limited to the second layer, and do not tie the second layer to the first layer. The two layers may have vertically stacked machine direction yarns.

Abstract: An improved system in a paper making process of forming and dewatering fiber/aqueous dispersion (44) by submerged drainage in which air does not penetrate the fiber/aqueous dispersion (44) nor the paper web as it is being formed; the dewatering being accomplished by altering the natural tension of the water meniscus so as to induce enhanced drainage of water from the aqueous dispersion (44) of paper making fibers, especially in the wetter end of the system.

Abstract: The present invention is a method of bonding a fibrous wet laid nonwoven fabric-like product using bacterial cellulose as a binder. The bacterial cellulose most useful for the invention is the type formed in an agitated culture. Microorganisms of the genus Acetobacter which are genetically adapted to be good cellulose producers under agitated conditions are preferred cellulose producers. From 1-30 % of the bacterial cellulose may be added to a watter slurry of other sheet forming fibers as a binder. Preferably 20 % or less bacterial cellulose is used since higher amounts retard drainage rates significantly. Bacterial cellulose conveys many desirable properties such as excellent hydrophilicity with low air porosity and high tensile index. It may be used in many cases as a total replacement for the latex binders now used for manufacture of nonwoven fabrics. Bacterial cellulose is especially well adapted for the manufacture of pattern bonded sheets.

Abstract: A non-woven fabric having a pattern defined by an array of discrete areas having a reduced fibre density but which are substantially free of perforations is produced by supporting a freshly wet laid web of the non-woven fabric on a porous surface and directing spaced jets of fluid against the unsupported side in order to displace fibres within discrete areas whilst maintaining in position a proportion of fibres that are within those areas and that are adjacent the porous surface. The fabric web may be supported on a Fourdrinier wire (1) and the jets of fluid (e.g. water) may be directed through the apertures in a perforated cylinder (6), the fluid being supplied under pressure from a water-knife device (11). The apertures in the cylinder (6) preferably have a cross-section that increases in the direction of the water jets. Vacuum may be applied through the Fourdrinier wire (1) by means of a vacuum box (10) and vacuum may also be applied within the cylinder (6) from means (17) in order to remove excess water from within the cylinder (6).

Abstract: A process and system for making a domed product by forming domes or protrusions into a sheet. The process including: moving a die set comprising one or more domes or protrusions, wherein the die set selectively registers with the sheet; latching the die set to the sheet after the selectively registering; and pressing the one or more domes or protrusions of the die set into the sheet for a period to obtain the domed product, wherein the die set moves independently from the sheet prior to the latching.
