摘要:
A papermaking machine for the production of a fibrous web including a plurality of rollers and a structured fabric moving along the rollers. The structured fabric includes a plurality of weft yarns and a plurality of warp yarns woven with the plurality of weft yarns to produce a weave pattern, the plurality of warp yarns being a plurality of paired warp yarn sets. Each paired warp yarn set including a first warp yarn and a second warp yarn. Within the weave pattern the first warp yarn forms a float over at least four weft yarns and weaves with a single weft yarn immediately adjacent with the float. The second warp yarn having an inverse pattern to the first warp yarn, with the second warp yarn weaving with another single weft yarn that is not adjacent to the single weft yarn with which the first warp yarn is woven.

A method of designing an RPG. A computerized model is created of a shield mesh opening with lines of a net intersecting at nodes and with hard points positioned at least at select nodes. The effectiveness of the mesh opening at a plurality of obliquity angles is determined. In the model, a change is made to the size of the mesh opening and the effectiveness is determined again at a plurality of different obliquity angles. Iterations of this process allow an optimal mesh opening size to be determined for a threat such as an RPG.

The present invention provides a fabric for a papermaking machine. The fabric includes a machine facing side and a web facing side having pockets formed by warp and weft yarns. Each pocket is defined by four sides on the web facing side, three of the four sides each being formed by a knuckle of a single yarn, and one of the sides being formed by a knuckle of a weft and of a warp yarn, wherein the weft yarn also defines a bottom surface of the pocket.

A fibrous web including a fibrous construct having at least one formed surface feature. The surface feature including a topographical pattern reflective of a weave pattern in a fabric used in a papermaking machine having a through-air drying system. The fabric including a single layer of yarns arranged in a repeating weave pattern, each weave pattern including a plurality of warp yarns substantially oriented in a machine direction (MD) defining MD yarns; and a plurality of weft yarns substantially oriented in a cross machine direction (CD) defining CD yarns. The MD yarns each having at least one long float within the weave pattern. Each long float being adjacent to at least one other long float of an MD yarn. The weave pattern being a plain weave apart from the long floats.
摘要:
Forming fabric for making a bulky web. The fabric includes a machine facing side and a web facing side comprising pockets formed by warp and weft yarns. A bottom of the pockets is formed by an exchange of the warp and weft yarns. A contact plane of the web facing side includes elongated warp knuckles. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
摘要:
Monofilament made from a polymeric blend, wherein the polymer blend includes at least a first and a second polymer component wherein the first polymer component is polyamide (PA) 612 added to the blend in an amount of 50% to 99% by weight and that a second polymer component is at least one other polyamide added to the blend in an amount of 1% to 49% by weight and that per denier the monofilament has a resistance to withstand at least 60 cycles of abrasion testing.
摘要:
A composite forming fabric (10) comprising a paper side layer (12) having a paper side surface, a machine side layer (14) having a bottom wear side surface, and a plurality of pairs of first and second intrinsic, interchanging weft binder yarns (16,18,20, . . . 34) for binding together the paper side layer (12) and the machine side layer (14). At least of said plurality of pairs of first and second intrinsic, interchanging weft binder yarns have at least four segments (S1-S4) in the paper side layer (12) within each repeat of the weave pattern in the fabric, and these segments provide an unbroken weft path in the paper side surface. Each of the first and second intrinsic, interchanging weft binder yarns (16,18,20, . . . 34) of each binder pair having at least four segments (S1-S4) in the paper side layer (12) within each repeat of the weave pattern binds to at least one warp yarn (2-20) in the machine side layer (14) vertically underlying one of the segments (S1-S4).
