Non woven filter material is a new type of material, which is a fiber network structure formed by high-strength polyester fibers or polypropylene fibers through mechanical, thermochemical and other methods. It is different from traditional fabrics in that it does not require weaving or weaving processes, and has the characteristics of uniform thickness, diverse pore sizes, and high fabric performance.
Performance characteristics of non-woven filter materials
Good filtering effect
Non woven filter materials have pores and voids of different diameters, which can be used to effectively filter different particles, fibers, and harmful substances, ensuring water and air quality.
High strength and good stability
Compared with traditional woven materials, non-woven filter materials have higher strength and stability due to their special material and simple manufacturing process, making them less prone to deformation, delamination, and aging.
Good corrosion resistance
Non woven filter materials can withstand natural environments such as sunlight and rainwater at room temperature, and are not easily corroded by chemical substances, with good corrosion resistance and aging resistance.
Good breathability
Non woven filter materials have a higher porosity, which makes the transfer of gas and liquid more significant, and have good breathability and permeability.
Ease of handling
Non woven filter materials can be personalized in different shapes and sizes according to specific filtration requirements, making them easy to process and use. At the same time, it also has high value in recycling and processing.
The use of non-woven filter materials
Air filtration
Non woven filter materials can be used as the filter element of air filters to filter out impurities such as bacteria, viruses, and dust in indoor air, effectively improving air quality and human health.
Liquid filtration
Non woven filter materials can be used for liquid filtration, such as in the manufacture of water treatment equipment, pure water machines, water dispensers, etc. It can effectively filter pollutants and impurities such as microorganisms, resulting in a significant improvement in the quality of the effluent.
Medical use
Non woven filter materials can be used in the medical field, such as medical masks, surgical gowns, surgical drapes, disinfectant cloths, etc. It can provide good protection, isolation, and sterilization, ensuring the health of medical staff and patients.
Building purpose
Non woven filter materials can be used in the construction field, such as filters for ventilation and air conditioning, roof waterproofing materials, groundwater drainage boards, etc. It has waterproof, soundproof, and thermal insulation properties, which can optimize indoor environment and improve building quality.
Automotive Applications
Non woven filter materials can be used in the automotive industry, such as air filters, oil filters, car seats, etc. It can protect against impurities such as bacteria, viruses, moisture, and dust in the air inside the car, improving the quality of the car environment and driving comfort.
The main differences between non-woven filter materials and woven filter materials
Structure
The fibers of non-woven filter materials are interwoven in a disordered form, forming pores, and the filtered material is difficult to return to the airflow. Machine woven filter materials are interwoven with parallel yarns to form a grid structure, and the filtered material is easily returned to the airflow.
Performance
The fiber distribution of non-woven filter materials is relatively uniform, with high filtration efficiency and service life, and easy to clean and maintain. Woven filter materials have the advantages of tight grid structure, high tensile strength, and low resistance, and can also be maintained and cleaned.
Scope of application
Non woven filter materials are suitable for various fields, such as food and beverage manufacturing enterprises, chemical production enterprises, medical and health fields, etc., due to their high filtration efficiency, long service life, and high reliability. Machine woven filter materials are more suitable for high-speed gas filtration work, such as automobile manufacturing, high-speed trains, aerospace and other fields.
Price
Due to differences in production processes and fiber quality, the price of non-woven filter materials is usually slightly lower than that of woven filter materials. However, the specific price also needs to consider factors such as service life, cleaning and maintenance costs.
Conclusion
In short, non-woven filter materials and woven filter materials each have different characteristics and are suitable for different fields and environments. When selecting filter materials, it is necessary to make a reasonable choice based on specific usage requirements and budget.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
