Characteristics of Industrial Nonwoven Fabric

Physical Properties

• Lightweight: It is light in weight, easy to handle and construct, and can reduce the overall weight of the building. For example, laying lightweight non-woven fabrics on the roof will not impose excessive pressure on the roof structure.
• Good Flexibility: It can adapt to building structures of different shapes and surfaces, and can be bent or folded, showing obvious advantages in pipe insulation, wrapping of special-shaped building components, etc.
• Dimensional Stability: It can maintain stable dimensions under different environmental conditions without obvious deformation due to factors such as temperature and humidity changes. For instance, polyester long-fiber non-woven fabrics in roof waterproof membranes can maintain their shape for a long time to ensure waterproof effects.

Mechanical Properties

• High Strength: It has high tensile strength and tear strength, and can withstand certain external pulling and tearing forces. For example, in the wall reinforcement layer, it can effectively enhance the tensile performance of the wall.
• Puncture Resistance: It can resist punctures from sharp objects, protecting the building structure and other materials from damage. For example, in basement waterproofing projects, it can prevent underground sharp objects from piercing the waterproof layer.

Chemical Properties

• Corrosion Resistance: It has good resistance to chemicals such as acids and alkalis, and can be used in harsh chemical environments to extend the service life of building materials. For example, non-woven fabrics with corrosion resistance can play a protective role in areas of industrial plants exposed to chemicals.
• Aging Resistance: It has good aging resistance, can withstand the effects of ultraviolet rays, oxidation, and other factors, maintain stable performance for a long time, and reduce building maintenance costs.

Functional Properties

• Waterproofness: Through special treatment or compounding with other waterproof materials, it can have good waterproof performance, effectively blocking the penetration of rainwater and groundwater, and is commonly used in waterproof projects for roofs, basements, etc.
• Breathability: It allows air to circulate, regulates the humidity and air pressure inside the building, prevents water vapor condensation, avoids mold growth, and keeps the interior dry and comfortable.
• Thermal Insulation: The pores between fibers form a static air layer, which can effectively block heat transfer, reduce building energy consumption, and can be used for thermal insulation of walls, roofs, pipes, and other parts.
• Sound Absorption and Noise Reduction: The porous structure can absorb and attenuate sound waves, reduce noise propagation, and improve the acoustic environment inside the building. It is commonly used in places with high sound insulation requirements such as conference rooms, theaters, and machine rooms.

Production Processes

• Spunbond Method: Polymer chips are melted, extruded, and spun to directly form continuous filaments, which are then netted and bonded to form non-woven fabrics. Non-woven fabrics produced by this method have high strength and good uniformity, and are commonly used in roof waterproof membranes, house wrapping layers, etc.
• Meltblown Method: The molten polymer filament is stretched into extremely fine fibers by high-speed hot air flow, condensed into a web, and then reinforced by self-bonding or thermal bonding. Meltblown non-woven fabrics have an ultra-fine fiber structure and good filtration performance, and can be used for air filtration, dust filtration, etc.
• Needle Punching Method: After carding short fibers into a web, it is repeatedly punched with barbed needles to make the fibers entangle with each other, thus reinforcing into fabric. Needle-punched non-woven fabrics are soft, have high strength, and are widely used in thermal insulation materials, geotextiles, and other fields.
• Wet Method: Using water as a medium, fiber raw materials are dispersed in water to form a fiber suspension, which is then made into non-woven fabrics through processes such as papermaking, dehydration, and drying. Wet-process non-woven fabrics have uniform fiber distribution and are suitable for producing thin and high-strength products, such as gypsum board facing paper and sound-absorbing ceiling materials.

Application Fields

Waterproof Projects

• Roof Waterproofing: As the base material for roof waterproof membranes, it is compounded with waterproof materials such as asphalt to enhance the strength and aging resistance of the waterproof membrane, improve the roof waterproof effect, and extend the service life of the roof.
• Basement Waterproofing: Laid on the walls and floors of the basement to block the penetration of groundwater, protect the basement structure from water erosion, and prevent basement leakage.

Thermal Insulation Projects

• Wall Insulation: Pasted or sandwiched in the middle of the wall to form an insulation layer, reducing heat exchange between indoor and outdoor, lowering building energy consumption, and improving indoor comfort.
• Roof Insulation: Laid on the roof, it effectively blocks solar radiant heat from entering the room and prevents indoor heat loss, playing a role in thermal insulation.
• Pipe Insulation: Wrapped around hot water, steam, and other pipes to reduce heat loss in the pipes, save energy, and prevent dew condensation on the pipe surface.

Sound Absorption and Noise Reduction Projects

• Sound Absorption for Walls and Ceilings: Installed on the surface or inside of walls and ceilings to absorb room noise, improve the indoor acoustic environment, and reduce noise interference.
• Sound Insulation Barriers: Used around roads, railways, factories, etc., to block the propagation of traffic noise, industrial noise, etc., to the surrounding environment and protect the health of residents and staff.

Other Applications

• Geotextiles: Used in geotechnical projects such as roads, bridges, and dams to play roles in reinforcement, isolation, filtration, drainage, etc., improving the stability and durability of geotechnical structures.
• Cement Packaging Bags: As a material for cement packaging bags, it has the properties of high strength, moisture resistance, breathability, etc., which can effectively protect the quality of cement and facilitate the storage and transportation of cement.
• Filtration Materials: Used in building ventilation systems, water treatment systems, etc., to filter dust and impurities in the air and suspended matter and impurities in water, ensuring the quality of air and water.
