Abstract
Papermachine clothing, for instance, a loop of imprinting fabric, is disclosed which is so woven that a top-surface-plane thereof is defined by coplanar crossovers of filaments of at least two sets of filaments (i.e., warp and shute filaments) and so that sub-top-surface crossovers are distributed in a predetermined pattern throughout the clothing. Specific weaves are disclosed wherein the top-surface crossovers act corporately to define a top surface comprising a bilaterally staggered array of wicker-basket-like cavities which cavities each span at least one sub-top-surface crossover. Such clothing is particularly useful for making soft, absorbent paper of relatively low density, and relatively isotropic stretch properties when creped.
Claims17
A loop of fabric for use on a papermaking machine, said fabric comprising a first set of filaments which filaments are disposed generally parallel with respect to each other and a second set of filaments which filaments are generally disposed in parallel relation to each other and which filaments are relatively steeply angularly disposed with respect to the filaments of said first set of filaments, said sets of filaments being interwoven and complementarily serpentinely configured to provide a predetermined first grouping of coplanar top-surface-plane crossovers of both said sets of filaments, and a predetermined second grouping of recessed sub-top-surface crossovers, said top-surface-plane crossovers being in spaced relation to define an array of wicker-basket-like cavities which cavities are disposed in a sufficiently staggered relation in both the machine direction and the cross machine direction to preclude adjacent said cavities being aligned in either the machine direction or the cross machine direction, each said cavity spanning at least one said sub-top-surface crossover and perimetrically enclosed by a picket-like-lineament comprising a plurality of said top-surface-plane crossovers.
