Abstract
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.
Claims19
A multiaxial fabric, comprising:
- a multiaxial fabric base in the form of a spiral wound formed endless loop flattened into a first and second layer along a first fold line and a second fold line;
- said base fabric comprising a first fabric strip, said first fabric strip being woven from machine direction (MD) and cross-machine direction (CD) yarns in a predetermined manner such that a distance between one pair of adjacent CD yarns is different than that between another pair of adjacent CD yarns.
A method of forming a multiaxial fabric for use in a paper machine, said method comprising the steps of:
- forming a base fabric from a first fabric strip, which is woven from machine direction (MD) and cross-machine direction (CD) yarns in a predetermined manner such that a distance between one pair of adjacent CD yarns is different than that between another pair of adjacent CD yarns;
- forming said base fabric into a spiral wound formed endless loop;
- flattening said base fabric into a first and second layer along a first fold line and a second fold line;
- and
- seaming said first and second layer along said first and second fold lines.

A multilayer multiaxial fabric for use with a paper machine, said fabric comprising:
- a first woven layer having a plurality of interwoven MD and CD yarns and having predetermined distances between adjacent ones of said CD yarns such that a distance between one pair of adjacent CD yarns is different than that between another pair of adjacent CD yarns;
- and
- a second woven layer having a plurality of interwoven MD and CD yarns and having predetermined distances between adjacent ones of said CD yarns such that a distance between one pair of adjacent CD yarns is different than that between another pair of adjacent CD yarns.

- forming a second woven layer having a plurality of interwoven MD and CD yarns and having predetermined distances between adjacent ones of said CD yarns such that, a distance between one pair of adjacent CD yarns is different than that between another pair of adjacent CD yarns;
- and
- joining said first woven layer and said second woven layer together by needling.
