Single-layer and 1.5-layer Forming Fabrics
Single-layer
Single-layer
In flat woven type fabric, the warp, during weaving, is composed of yarn which is referred to as MD yarn. In order to make endless loops, fabrics are joined by connecting the warp yarn at the end of each fabric. FILCON uses automated seaming machines for connecting fabrics.
Plain Weave
Plain Weave (2-shed)
The most basic weave. Used as upper layer for triple-layer because of its good surface.
Long Crimp Weave
Long Crimp Weave (3-shed)
Also provides a good surface.
Level Weave
Level Weave (4-shed)
Provides good stretch and drainage properties. Small fiber loss and good sheet release.
3/1 Satin Weave
3/1 Stain Weave (4-shed)
Suitable for multipurpose. Provides good stretch, drainage, sheet, support and abrasion resistance properties.
4/1 Satin Weave
1/4 Satin Weave (5-shed)
Provides better stretch and drainage properties than 4-shed. Retention can be improved by increasing weft yarns. Primarily used on tissue machines.
OS Series – Single-layer Forming Fabrics
OS Series – Single-layer Forming Fabrics

1.5-layer
1.5-layer
This is a 5-shed single-layer fabric woven with extra yarns, giving it properties usually found in double-layer fabrics. The extra yarns provide better sheet side smoothness as well as improved retention. Thanks to its unique structure, it delivers very good drainage and ease of cleaning. This structure, generally referred to as 1.5-layer, is a FILCON’s original design.
5-shed with Extra Yarns
5-shed with Extra Yarns
Provides good sheet-side smoothness, improved retention and ease of cleaning.
OFE Series – 1.5-layer Forming Fabrics
OFE Series – 1.5-layer Forming Fabrics
This 5-shed single-layer fabric woven with extra yarns has the properties usually found in double-layer designs. The extra strands provide better sheet side smoothness and helps to improve sheet release and retention. It has very good drainage and is easily cleaned.
