Paper Machine Clothing Single Layer Forming Fabric

Share:

The single-layer forming fabric is the simplest forming fabric. They are woven in 4-shed(Provides good stretch and drainage properties. Small fiber loss and good sheet release.), 5-shed(Provides better stretch and drainage properties than 4-shed. Retention can be improved by increasing weft yarns. Primarily used on tissue machines.), and 8-shed for different applications. 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. PFM Screen uses automated seaming machines for connecting fabrics. According to their weaving shed, single-layer forming fabrics could be used for the manufacture of kraft papers, tissue papers, writing & printing papers, and so on.
