Patent ID: 7806147

Claim:
A papermakers dryer fabric (C to G) having paper web carrying and non-paper web carrying surfaces (U. 1 , U. 2 ), the fabric being adapted to carry a paper web on the paper web carrying surface and woven from machine direction yarns ( 1 ) and cross machine direction yarns ( 2 ; 6 . 1 , 6 . 2 ; 15 , 16 ) wherein the yarns ( 1 , 2 ; 6 . 1 , 6 . 2 ; 15 , 16 ) cross over each other to create void volume (V.T, V.U 1 , V.U 2 ) both inside the structure (T) of the fabric (C to G) and at the surfaces (U. 1 , U. 2 ) of the fabric (C to G), wherein the machine direction yarns ( 1 ) and the cross machine direction yarns ( 2 ; 6 . 1 , 6 . 2 ; 15 , 16 ) are interlaced so that virtually all of the void volume (V.U 1 , V.U 2 ) is exposed to the paper web carrying and non-paper web carrying surfaces (U. 1 , U. 2 ), wherein the machine direction yarns and the cross machine direction yarns are substantially round in cross section, wherein the void volume (V.U 1 , V.U 2 ) at the surfaces (U. 1 , U. 2 ) of the fabric (C to G) ranges from 0 to 10,000 mm 3 /100 mm 2 , and wherein the void volume (V.U 1 , V.U 2 ) at the surfaces (U. 1 , U. 2 ) of the fabric (C) and the void volume (V.T) inside the structure (T) of the fabric (C) have a ratio between 1:1 and 30:1.
