摘要:
A fabric for a papermaking machine is provided. The fabric includes a machine facing side and a web facing side comprising pockets formed by warp and weft yarns. Each pocket is defined by four sides of the web facing side. Two of the four sides are each formed by a warp knuckle of a single warp yarn that passes over at least three consecutive weft yarns to define the warp knuckle. The other two of the four sides are each formed by a weft knuckle of a single weft yarn that passes over two consecutive warp yarns to define the weft knuckle.

Fabric for making a bulky web. The fabric includes a machine facing side and a web facing side comprising pockets formed by more MD yarns than CD yarns. Adjacent pockets are offset from each other and are defined by MD and CD 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.

Forming fabric for making a bulky web. The fabric includes a machine facing side and a web facing side having pockets formed by warp and weft yarns. The pockets are defined by more than four sides on an upper plane of the web facing side. 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:
Forming fabric that includes a top layer having a plurality of first top warp yarns woven with a plurality of top weft yarns. A bottom layer includes a plurality of first bottom warp yarns woven with a plurality of bottom weft yarns. A plurality of second top warp yarns is woven with some of the plurality of top weft yarns and with some of the plurality of bottom weft yarns. A plurality of second bottom warp yarns is woven with some of the plurality of top weft yarns and with some of the plurality of bottom weft yarns. At least one of the plurality of second top warp yarns weaves to the bottom layer with a short plain weave. At least one of the plurality of second bottom warp yarns weaves to the bottom layer with a short plain weave.
摘要:
A fabric for papermaking usable in the forming section of a paper making machine, having a first weft system, a second weft system and a third weft system; and a plurality of warp systems, each warp system having at least one warp yarn, each warp yarn binding with one of the first weft system, the third weft system, the first and second weft systems, and the second and third weft systems; wherein a first warp system is an exchange warp system.
摘要:
A papermaker's fabric, usable in the forming section of a paper machine, having two layers of cross-machine-direction (CD) yarns. Interwoven with the CD yarns is a system of MD yarns. The MD yarns are grouped into alternating pairs comprising a crossing pair having a first MD yarn and a second MD yarn and a second pair having a third MD yarn and a fourth MD yarn. The first MD yarn and the second MD yarn combine to weave each CD yarn in the first layer and cross between the first layer and the second layer. The left and right warp yarns in the pairs are aligned in such a way that like adjacent yarns from adjacent pairs have MD cell lengths equal to or less than the MD cell lengths from non-like adjacent yarns from adjacent pairs. The third MD yarn is interwoven with the first layer of CD yarns and the fourth MD yarn is interwoven with the second layer of CD yarns. In this manner, a paired warped triple layer forming fabric may be produced which minimizes drainage and crossover point topographical markings.
摘要:
A composite papermaking fabric having an upper support fabric including upper warp and weft yarns and a lower contact fabric including lower warp and weft yarns. The upper fabric is woven in a first weave pattern which forms a support surface and the lower fabric is woven in a broken twill weave pattern which forms the contact surface. The composite fabric includes paired binder yarns which weave in alternating sequences with the upper and lower fabrics binding them together. The broken twill weave pattern provides plural floats of cross-machine direction yarns passing outwardly of a plurality of adjacent lower warp yarns forming a plurality of adjacent cross-machine direction floats. Certain of the paired floats comprise a lower weft yarn and a binder yarn while others may comprise two lower weft yarns. The lower weft yarn floats are positioned to shield and protect the binder yarn floats along their entire length.
摘要:
A wear resistant dual layer papermaking fabric, of stable construction, having a fiber support surface and a machine contact surface. The fabric comprises first picks of weft yarn are woven with warp yarns to form weft yarn floats of equal length arranged in a twill pattern diagonally over the support surface. Second picks of weft yarn are woven with the warp yarns to form weft yarns floats of equal length arranged in a twill pattern diagonally across the contact surface. The weave pattern provides that the warp yarns inter-engage with the first and second picks in a balanced weave pat parallel and stable.
摘要:
A woven fabric for use in papermaking machines and particularly with through air drying machines. The fabric comprises a paper support surface having spaced diagonal rows pockets which are effective to create diagonal rows of uncompressed paper forming fibers over the surface of paper formed on the papermaking machine. The rows of pockets are separated by diagonal strips of support surface arranged along substantially a single plane. The diagonal strips provide support areas over the width of the paper forming fibers which firmly secure the fiber sheet with the papermaking fabric during paper forming. The strips also produce diagonal rows of compressed paper forming fibers which provide for a more stable paper product.
