<p>A papermaker~s fabric includes first and second layers (116,114) of cross- machine-direction (CD) yarns (121-132) and a plurality of machine-direction (MD) yarns (141-158) interwoven therewith and arranged in groups each having a first, two second, and two third MD yarns (141,147,153). The first MD yarn binds with two CD yarns of the first layer and with two CD yarns of the seco nd layer. The second MD yarns (142,146,148,152,154,158) bind with only one CD yarn of the first layer and floats over at least two consecutive CD yarns of the second layer. The third MD yarns (143,145,149,151,155,157) bind with onl y one CD yarn of the first layer and floats over at least two consecutive CD yarns of the second layer. The second MD yarns are offset from the third MD yarns in a direction parallel to the MD yarns. The first MD yarn is between the two second MD yarns which are between the third MD yarns so as to form a continuous air channel (160).</p> |
