Woven fiberglass is a type of filter material designed for use in high temperature environments. It is created through a series of processes including drawing, spinning, warping, texturizing, weaving, finishing, and laminating. This material possesses exceptional qualities such as the ability to withstand high temperatures (up to 260℃), high tensile strength, resistance to oxygen and corrosion, and a long lifespan. As a result, it finds extensive applications in dust filtration across various industries including cement plants, power plants, carbon black plants, steel plants, and incinerators.

Woven fiberglass characteristic:
1. Exceptional heat resistance
Woven fiberglass filter fabric can withstand continuous use in temperatures ranging from above the dew point of acid to 260°C, with a maximum temperature resistance of 280°C. Even when exposed to burning particles and sparks, the filter material will not ignite. Unlike other filter materials, the glass fiber fabric remains unchanged in both physical and chemical properties, as well as color, even after being subjected to a 2-hour baking process at 280°C.
2. Remarkable strength and minimal stretching, maintaining stability
The woven glass filter fabric exhibits warp and weft strength exceeding 2000N, ensuring it does not shrink under high temperatures and retains its original size, thereby preserving its filtering and cleaning performance. The elongation rate of the woven glass fabric is less than 3%. This means that during filtration operations, the weight of the filter material combined with the dust layer will not cause the filter bag to elongate, significantly reducing the occurrence of filter bag breakage caused by air pressure cleaning.
3. Precise filtration capability
The fiberglass filter fabric is equipped with a PTFE membrane that consists of small and evenly sized micropores (ranging from 0.10 to 2.0μm). This allows it to effectively separate any dust particles that are larger than the diameter of these micropores. Moreover, it exhibits a remarkable ability to collect PM10 (respirable dust) and PM2.5 (respirable dust), both of which pose a serious threat to human health. Consequently, the filtration efficiency of this fabric is consistently high, making it effortless to achieve emission standards of less than 20mg/m³, 10mg/m³, or even 5mg/m³.
4. Thin, pliable, and effortless to clean
The woven fiberglass material boasts a thickness of less than 0.8mm, which varies depending on the fabric's weight. This is merely one-third of what the needle felt filter material measures. Additionally, it is woven using texturized yarn, giving it a soft and flexible texture. During the process of dust cleaning, the fiberglass cloth adopts a serpentine motion, making it easy for the dust to detach. The pressure required for dust removal is minimal, resulting in fewer instances of dust cleaning. As a result, the consumption of compressed air is significantly reduced, maintenance needs are minimized, and operational costs are effectively saved.
5. Protection against oxidation and corrosion
Fiberglass filter fabric remains unaffected by oxygen or nitride, eliminating the need to worry about varying oxygen levels in the dust collector. Woven glass cloth boasts exceptional resistance to corrosion. Furthermore, when the filter material is infused with PTFE, a dense protective film forms on the surface of the glass fiber cloth, preventing erosion and ensuring the durability of the fiberglass cloth during operation.
6. Outstanding durability against folding
The woven fiberglass filter fabric is made from glass yarns and undergoes meticulous chemical treatment, resulting in a folding resistance several times higher than that of regular filter materials. This enhanced durability allows the filter material to endure long-term shrinkage and expansion without sustaining any damage, thereby guaranteeing its longevity.
7. Ideal for working in damp environments, this fabric is resistant to water and oil.
The filter cloth made from glass fiber is highly resistant to hydrolysis. The fabric's base material has undergone treatment using technology that repels water and oil. Through rigorous testing, it has been determined that the level of waterproofing is no less than 4.5. This ensures that the filter material does not absorb water, preventing any hardening issues that may occur after condensation.
