Paper Making Endless Press Felt/Seam Press Felt/ Pick Up Felt/ BOM
FeltProduct DescriptionThe press felt plays an important role in
removing the water from the paper web after the forming section,
and at the same time imparting smoothness and conveying it to the
dryer section. For this reason, the press felt needed to provide
the following functions: water removal, smoothness, and
runnability.In recent years, larger and faster paper machines
require press felts of even higher consistency and quality. At
Huatao, we seek uniformity in every aspect of the production
process. Using digital controls, we are able to manage the entire
process with great precision and implement a high level of quality
control in all aspects. Strength: Press felt has a
certain strength. The periodic stress and fatigue in the process of
pressing can cause the felt elongation, compression and horizontal
direction strain. When felt is used too long, the deformation will
reduce the felt quality and reduce felt service life.Void
Volume: The void volume refers to the measured value of water
capacity of press felt, especially the maximum water capacity of
the press felt under the load effect. Felt shall have a certain
volume of voids to absorb the water pressed out of the wet paper
sheet.Permeability: Permeability refers the performance of
water or air through felt under certain pressure or vacuum
conditions. Press felt must have good permeability. The fluid
pressure in pressure zone is too high to cause wet paper embossing.
Fillers, binders, fine fibres and other impurities can clog felt
pores and reduce felt permeability. So the felt must be cleaned
regularly to keep felt clean. And as far as possible to avoid
impurities to block felt pores, maintain its smooth, water
permeable and large enough void volume to play the auxiliary
dehydration of felt.Compressible Properties: Felt must be kept
in a certain degree of compressibility. After the felt is used, the
pore volume decreases gradually, and the diameter of the capillary
pipe becomes smaller. The result is that the channel of fluid flow
and the penetration of the felt are reduced, and the pressure of
pressed zone increases.Wear Resistance: The felt play the role
of transporting power, driving the action roller in press section.
Because the felt will produce friction with some fixed element
surface, such as felt suction tank or suction pipe, so the felt
must have good wear resistance.Forming Fabric / Forming
WirePolyester forming fabric can be divided into Single layer
forming fabric, 1.5 Layer forming fabric, Double Layer forming
fabric, 2.5 Layer forming fabric, SSB triple layer forming
fabric. 4-shed single layer Polyester forming
fabric is standard type of polyester forming fabric in paper
making, mainly used for producing cultural paper printing paper,
packing paper, and so on.5-shed single layer Polyester forming
fabric is suitable for making healthy, culture and packing
papers, etc.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.7-shed double
layer Polyester forming fabric is suitable for quality
printing paper and tissue paper etc.8-shed double
layer Polyester forming fabric is suitable for quality
printing paper, tissue paper, and the surface pulp and inner pulp
of the board paper, etc.8-shed, 16-shed double and a half
layer Polyester forming fabric are suitable for making
quality printing paper, tissue paper and surface pulp, inner pulp
and base pulp of the board paper, etc.Multi-shed
three-layer Polyester forming fabrics suitable for making
quality printing paper, tissue paper, cigarette paper,
etc. Dryer Fabric / Dryer ScreenPolyester Spiral Dryer Fabric
