A composite forming fabric for a papermaking machine woven according to a repeating fabric weave pattern is provided. The fabric includes a paper side (PS) layer having a PS surface, with the PS layer including PS warps and PS wefts interwoven in a first repeating pattern, and a machine side (MS) layer having a MS surface, with the MS layer including interwoven MS warps and MS wefts. A plurality of pairs of binder weft yarns each including first and second binder weft yarns that are interwoven with the PS warps and the MS warps to bind the PS and MS layers together in the composite forming fabric. In each pattern repeat of the fabric weave pattern at least three of the MS warps pass under each MS weft, where said at least three of the MS warps are co-located adjacent to one another with a further one of the MS warps separating a first of the at least three warps from the others of said at least three warps, and each of the MS warps interlaces with at least two non-adjacent ones of the MS wefts.

Composite forming fabric

A forming fabric for a papermaking machine woven according to a repeating fabric weave pattern is provided. The fabric includes a PS layer having a PS surface, with the PS layer including PS warps and PS wefts interwoven in a first repeating pattern, and a MS layer having a MS surface, with the MS layer including interwoven MS warps and MS wefts. A plurality of pairs of binder weft yarns is provided, with each of the pairs of binder weft yarns comprising first and second binder weft yarns that are interwoven according to a binder weft pattern with the PS warps and the MS warps to bind the PS and MS layers together in the composite forming fabric, and each interchanges between the layers at exchange points. In each pattern repeat of the fabric weave pattern, each of the MS warps forms one or more MS warp knuckles over single ones of the MS wefts, the MS warp knuckles of the MS warps are arranged in a broken twill having an offset mirror symmetric arrangement, and a direction of the broken twill reverses after an equal number of MS warp knuckles.

Guiding resistant forming fabric with balanced twill machine side layer

A papermaker's through-air dryer (TAD) fabric for use in the production of tissue and towel products. The fabric is woven according to a 10-shed, semi-duplex weave design in which the warp and weft yarns are arranged so as to form pockets of at least two differing sizes in a first planar fabric surface. The pockets are designed and arranged to impart a measure of bulk and absorbency to the paper products conveyed thereon by providing MD oriented recesses in the PS fabric surface into which a portion of the component fibers of the paper products formed on the fabric are deflected during manufacture.

Ten-shed semi-duplex through-air dryer fabric

A woven single layer papermakers' fabric, having a sheet support surface and a machine side surface, comprises a set of monofilament machine direction (MD) oriented warp yarns interwoven with a set of monofilament weft yarns in a ten shed repeating weave pattern, wherein in each repeat of the repeating weave pattern, at least 50% of the warp yarns each forms in the sheet support surface at least one long float over nine consecutive weft yarns. Adjacent long floats define elongated MD oriented pockets in the sheet support surface. The fabrics provide improved properties for forming and conveying topographically patterned products such as tissue.
