To further improve the characteristics of double-layer design, the sheet-side weft density is increased. The result is better sheet support that improves wire mark, retention, and the surface properties of the paper. In Addition, the number of weft yarns on the machine side are reduced so that the three-dimensional space (void volume) is increased for enhanced drainage capability. This design is commonly known as 2.5-layer weave, or “EX” weave.
7-shed “EX” weave
Provides an excellent surface property. Enhanced sheet support enables better surface smoothness. With the open-structured back side realizes improved drainage and contamination prevention.
8-shed “EX” weave
Provides just about the same properties as 7-shed. It has higher drainage capability.
14-shed
Improved LL-E type. Superior in surface property and abrasion resistance due to its long-knuckle structure on the wear side.
16-shed “EX” weave
Improved 8-shed“EX” type. It has an excellent abrasion resistance property.
LL-E Series – 2.5-layer Design
Sheet side properties are improved by increased sheet support points. The open-structured wear side enables improved drainage capability and reduced contamination.
