摘要:
A pinseam press fabric is smoothed in the area of the seam by depositing polyurethane particles having a size of about 1 to 500 micrometers across the seam of the felt defined by the ends of the fabric. The polyurethane particles are drawn into the seam end by the application of a vacuum. Once the particles are deposited, the fabric is heated so that the polyurethane particles melt to form a polymeric matrix.

摘要:
Belt and method of making a belt for a paper making machine. The belt includes a flat woven material having a top side surface and a bottom side surface and two terminal ends separated in a machine direction. Folds formed in the flat woven material are separated in the machine direction, so that the two terminal ends are located under the bottom side surface. Seam loops are located at the folds, and the two terminal ends one of are arranged adjacent each other and overlap each other in a region offset from a center between the folds. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
摘要:
A mixture contains polymer particles along with solids or fibers that can be utilized in press felts (or fabrics) for the press section of a papermaking machine and a method of making the mixtures are described.
摘要:
A composite paper machine fabric substrate of a base and batt formed from polyamide is reinforced by a polymer having a glass transition temperature (TG) of −40 to 15° C. that is dispersed at below the face side surface of the fabric substrate to mechanically bond to the substrate. The polymer is thermoplastic enabling an improvement in flexibility and overall wear while at the same time permitting porosity necessary for proper drying of paper.
摘要:
A paper machine fabric INCLUDES A fabric having a roll side and a paper side and a surface matrix on the paper side; and a chrome complex treatment in the surface matrix. The chrome complex treatment chemically reacts with the surface matrix and orients hydrophobic organic chains away from the surface of the fabric and thereby provides enhanced release property.
摘要:
There is provided an industrial fabric comprising a layer of batt of fibres optionally needled to a base cloth, whereby during manufacture of the fabric a dispersion of particulate, polymeric material has been applied to the layer of batt of fibres and thermally activated to provide a discontinuous layer containing a mixture of batt fibres and a polymer-baft fibre matrix.
摘要:
An industrial fabric including a base layer, a batt layer and at least one low-melt polymeric film layer, which has been needled into the batt layer and subsequently thermoformed to at least partially encapsulate the fibers of the batt layer.
