1) Airflow velocity is reduced to the minimum. 2) resistance up to 2 times the initial resistance 3) there can not repair the leakage.

1, to keep the device environment cleaning, cleaning equipment before the ventilation pipe, the pipe inside the garbage, dust, rust and other clean-up; 2, the device must be unpacked in the field before the packaging, the appearance of inspection, check the contents of the filter paper, sealant and frame for damage; side length, diagonal and […]

High efficiency filter test method Before the air volume test, the fan must first check whether the normal operation, the system components are installed correctly, with or without obstacles (such as whether the filter has been blocked, block), all valves should be fixed in a certain open position , And must be measured to measure […]

1. Flexible entanglement, does not affect the original fiber characteristics, does not damage the fiber 2. Appearance than other non-woven materials closer to traditional textiles 3. High strength, low fluff 4. High moisture absorption, rapid moisture absorption 5. Good air permeability 6. Soft, drape 7. The appearance of changing patterns 8. Adhesive-free reinforcement, washable 9. […]

1, fiberglass roofing waterproof carpet high strength, good corrosion resistance; 2, good waterproof; 3, anti-brittle, anti-aging, strong anti-seasonal; 4, fiberglass roof waterproof carpet excellent anti-leakage.

Most fiberglass nonwovens are generally processed by needling or wet processes, but the North Carolina State University (NCSN) has successfully developed spunlaced nonwoven fabrics of glass fiber and polyester blends. Diameter 16um coarse denier glass fiber, with hydroentangling difficult to process, if the diameter of 6.5um fine denier glass fiber mixed, it is conducive to […]

In 1995 the United States BBA company developed the Interspun process and applied for a patent. Using this process, the surface of the fabric can be treated by hydroentangling, which can have a positive effect on the structure and properties of the fabric. In 1998 BBA signed a cooperation agreement with Fleissner, Fleissner for the […]

Wet spunlaced non-woven fabric strength and softness is equivalent to even more than the traditional dry spunlaced non-woven fabric, and wet spunlace non-woven fabric can not afford hair removal, the seam tensile strength is dry spunlace non- Woven fabrics twice, especially for the field of clothing.

The composite product of the method has the advantages of better spun bond strength and short fiber absorption than the spunbonded nonwoven fabric, and is even and soft than the spunbonded nonwoven fabric, has the function of absorbing water and absorbing oil, and has high strength and can be used as food wrapping cloth , […]

Because the price of wood pulp is much cheaper than the staple fibers commonly used in spunlacing, the fluff pulp has a good hygroscopicity and feel, so the resulting product is less expensive than all the fiber products and competitively priced, On the filter system is demanding. Products can be used as cloth (70% g […]
