Description
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.
● 4-shed single layer forming fabric
The 4-shed single layer is the most common polyester forming fabric
type used for papermaking. 4-shed single layer polyester forming
fabric mainly used for producing cultural paper, print paper,
tissue paper & toilet paper, packing paper, and so on. And it
provides good stretch and drainage properties. Small fiber loss and
good sheet release.
● 5-shed single layer forming fabric
This type is typically used for packing paper or for culture or
health paper, which provides better stretch and drainage properties
than 4-shed. Retention can be improved by increasing weft yarns.
Primarily used on tissue machines.
● 8-shed single layer forming fabric
8-shed single layer polyester forming fabric is the most
wear-resisting one in the single layer screen, which has long
performance life, but mesh print is relatively deep. It is mainly
used for copying the papermaking bag, craft paper, cardboard,
corrugated paper, and so on.
Feature
● 4-shed single layer forming fabric. Display excellent stretch, drainage and anti-wear property.
● 5-shed single layer forming fabric. Better stretch, drainage features and ideal for tissue machines.
● 8-shed single layer forming fabric. With enhanced retention, excellent drainage, and ease to clean.
Application
4-shed 5-shed single layer polyester forming fabric mainly used for producing cultural paper, print paper, tissue
paper, toilet paper & packing paper, and so on.
8-shed single layer polyester forming fabric is the most wear-resisting one in the single layer screen, which
has long performance life, but mesh print is relatively deep. It is
mainly used for copying the paper-making bag, craft paper,
cardboard & corrugated paper, and so on.
