Fiberglass Filter Cloth For Dust Filter Bag / High Temperature
Glassfiber Filter Cloth / Woven Fiberglass Filter Pockets
What is Glass Fiber Filter Cloth?
Glass fiber filter cloth is an ideal fabric for high-temperature
baghouse filter bags for various applications, thanks to the
excellent performance of glass fiber, the glass fiber filter cloth
has the advantages include high-temperature resistance, high
tensile strength, high acid, and alkali resistance, high oxygen and
corrosion resistance, long service life-time and so on. Glass fiber
filter fabrics are the optimal solution for environments with the
working temperature between 150℃ (300℉) ~ 260 ℃ (500℉).
Chemical Composition of Glass Fiber
The chemical composition of glass fiber can be divided into two
categories, Electrical fiberglass (E-glass fiber), and chemical
fiberglass (C-glass fiber).
Usually, the diameter of chemical glass fiber is about 8um, which
is 22Tex yarn, and the diameter of Electronic glass fiber is about
5.5um, which is 12.5Tex yarn.
In practical applications, the E- glass fiber filter cloth has
better property than C-glass fiber in temperature resistance,
tensile strength and durability. All Huading’s glass fiber filter
fabrics are made out by the E-glass.

filter cloth in the same thickness but with different materials and
different yarn diameter
| MaterialPerformance | Breaking tensile strength (N/25mm) | Abrasion resistance

| warp | weft |
| E-glass fiber 12.5tex yarn | 3900 | 3900 | 92 | 3267 |
| E-glass fiber 25tex yarn | 3000 | 2800 | 42 | 1183 |
| C-glass fiber 22.5tex yarn | 2500 | 2400 | 35 | 1000 |
Glass Fiber Filter Fabrics Yarn
Huading's fiber glass filter cloth are weaving by texturized fiber
glass yarn, this kind of yarn is utilizing high-pressure airflow
with special deformation process to make continuous fiber glass
bundle puffing, deformation, to get irregular loop, twining, and
knotting. This increase the contact area between the filter fabrics
and the gas, makes the fiber glass fabric in extra lower filtration
resistance, higher filter efficiency, and higher filtration
velocity. Under the same dust volume capacity, the filtering air
speed could be increased by 1/3, the system operation resistance
can be reduced by 1/4, and capture particles about 1um, dust
filtration efficiency no less than 99.5%.

Huading Glass Fiber Filter Cloth Surface-Treatment
As an industry air filter material, the glass fiber filter fabrics
must undergo surface treatment to achieve better corrosion
resistance, hydrophobicity and longer life-time.
According to different working conditions, Huading's glass fiber
filter cloth has the various surface treatment:
1.Silicon treatment,
2.Acid resistance treatment,
3.PTFE treatment,
4.Graphite treatment, etc.
The dust filter bags made out by the glass fiber filter fabrics has
the notable feature as following:
1.High-temperature resistance, the glass fiber filter material has
good heat resistance and could be used at a high temperature of
260-280℃. This not only saves the flue gas cooling cost of the dust
collector, but also reduces the risk of condensation.
2.Fiber glass fabrics will not shrink in working temperature below
280°C, it has much better dimensional stability than the organic
synthetic fiber.
3.The glass fiber filter media has stable chemical resistance
exclude strong acid and strong alkali. Even in the flue gas of
strong acid and strong alkali, it has few affect on service life.
4.The fiber glass filter fabrics with special surface treatment has
the properties of softness, lubrication and hydrophobicity, so the
dust collector filter bags made out by fiber glass has better
dedusting performance than other materials, dust could be removed
easily by reverse air blowing.
How To Choose Glass Fiber Filter Material
1.Choose the surface treatment of the glass fiber filter cloth
according to the working conditions of the dust point.
2.Select the weaving type of fiber glass filter fabrics according
to the dust removal method of the dust collector used. Generally,
woven glass fiber cloth is used for reverse air dust removal, and
nonwoven glass fiber needle felt is used for pulse jet cleaning.
3.Different filtration air speed shoud match different thickness of
filter fabrics, see the suitable air speed for different thickness
of glass fiber filter fabrics.
| Fabric thickness (mm) | 0.3 | 0.4 | 0.5 | 0.55 | 0.7 |
| Filtration Air speed (m/min) | ≤0.4 | ≤0.45 | ≤0.5 | ≤0.55 | ≤0.7 |
4.Determine the type of fiber glass filter fabrics according to the
requirements of emission concentration of environmental protection
standards respectively.
