The present invention provides a multilayer multiaxial woven fabric for a papermachine having a reduced interference pattern and accordingly improved dewatering uniformity. The present invention also provides a method of forming such multilayer multiaxial fabric.

Multiaxial fabrics

The present invention provides a multilayer multiaxial fabric for a paper machine having a reduced interference pattern and accordingly improved dewatering uniformity. The present invention also provides a method of forming such a multilayer multiaxial fabric.

A method of seaming an on-machine-seamable multiaxial papermaker's fabric to prevent yarn migration. The multiaxial fabric is in the form of an endless loop flattened into two layers along fold lines. CD yarns are removed from the folds to create ravel areas. This leaves the MD yarns unbound in the ravel areas. Seam loops are then formed from the unbound MD yarns at the folds. A thin porous material is sewn to the fabric at each fold. The porous material binds the CD yarns along the edges of the ravel areas while allowing passage of the seam loops through the material. The laminate prevents migration of CD yarn tails into the seam area.

Method of seaming a multiaxial papermaking fabric to prevent yarn migration

A papermaker's fabric is made by spirally winding a woven fabric strip. The fabric strip has first and second lateral edges, along which are a first and second lip, respectively. Each lip has at least one lengthwise yarn woven with crosswise yarns. Adjacent to and inward of the first and second lips on the fabric strip are a first and second gap, respectively, which lack lengthwise yarns but whose crosswise yarns join the lips to the body of the fabric strip. When spirally winding the fabric strip, the first lip is disposed within the second gap, and the second lip is disposed within the first gap, of adjacent turns to form a spirally continuous seam which is closed by attaching adjacent turns to one another.
