Papermaker's forming fabric with cross-direction yarn stitching and ratio of top machine direction yarns to bottom machine direction yarns of 2:3

A triple layer papermaker's fabric, comprising:

• a set of top machine direction (MD) yarns;
• a set of top cross machine direction (CMD) yarns interwoven with the top MD yarns to form a top fabric layer;
• a set of bottom MD yarns;
• a set of bottom CMD yarns interwoven with the bottom MD yarns to form a bottom fabric layer;
• and
• a set of stitching yarn pairs that interweave with the top MD yarns, wherein each of the stitching yarns interweaves with the bottom MD yarns;
• wherein the top MD yarns and the top CMD yarns are interwoven in a series of repeat units and the bottom MD yarns and the bottom CMD yarns are interwoven in a series of corresponding repeat units;
• wherein a stitching yarn pair is positioned between each adjacent pair of top CMD yarns;
• and
• wherein the set of top MD yarns comprises a first number of top MD yarns in each repeat unit, and the set of bottom MD yarns comprises a second number of bottom MD yarns in each repeat unit, and wherein the ratio between the first number and the second number is 2:3.

A method of making paper, comprising the steps of:

• (a) providing a papermaker's fabric, the papermaker's fabric comprising:
• a set of top machine direction (MD) yarns;

• a set of bottom MD yarns;
• a set of bottom CMD yarns interwoven with the bottom MD yarns to form a bottom fabric layer;
• and
• a set of stitching yarn pairs that interweave with the top MD yarns, wherein at least one of the yarns of each stitching yarn pair interweaves with the bottom MD yarns;
• wherein the top MD yarns and the top CMD yarns are interwoven in a series of repeat units and the bottom MD yarns and the bottom CMD yarns are interwoven in a series of corresponding repeat units;
• and
• wherein the set of top MD yarns comprises a first number of top MD yarns in each repeat unit, and the set of bottom MD yarns comprises a second number of bottom MD yarns in each repeat unit, and wherein the ratio between the first number and the second number is 2:3;
• (b) applying paper stock to the papermaker's fabric;
• and
• (c) removing moisture from the paper stock.
