PP Non-Woven Fabric, also known as polypropylene non-woven fabric, is a new type of material composed of directional or random fibers. This material has attracted much attention due to its unique properties and wide range of applications.
1. Characteristics of PP Non-Woven Fabric
PP Non-Woven Fabric has many excellent properties, mainly including:
Lightweight and soft: PP non-woven fabric uses polypropylene resin as the main raw material, with a specific gravity of only 0.9, about three-fifths of cotton, and has fluffy and good hand feel. Its fine fiber structure makes the finished product moderately soft and comfortable.
Moisture-proof and breathable: Polypropylene slices do not absorb water and have a moisture content of zero, so the finished product has excellent water repellency. At the same time, the porous structure composed of 100% fibers makes it extremely breathable, easy to keep the cloth dry and easy to wash.
Non-toxic and non-irritating: PP non-woven fabric is produced with FDA food-grade raw materials, does not contain other chemical ingredients, has stable performance, is non-toxic, odorless, does not irritate the skin, and is suitable for a variety of application scenarios.
Easy to decompose and environmentally friendly: The chemical structure of polypropylene is not strong, and the molecular chain is easy to break. It can be effectively degraded and enter the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within 90 days, greatly reducing the pollution to the environment.
Antibacterial and chemical resistance: Polypropylene is chemically blunt, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid, showing good antibacterial and chemical resistance.
2. Production process
The production of PP Non-Woven Fabric usually adopts a continuous one-step method of high-temperature melting, spinning, laying, and hot pressing and winding. The specific process includes:
Raw material preparation: Polypropylene pellets are selected as raw materials.
High-temperature melting: The polypropylene pellets are heated to a molten state.
Spinning: The molten polypropylene passes through the spinneret hole to form filaments.
Laying: The filaments form a mesh structure on the laying machine.
Hot pressing and winding: After hot pressing treatment, the mesh structure is made stronger and finally rolled into cloth.
3. Application Fields
PP Non-Woven Fabric is widely used in many fields due to its unique properties:
Environmentally friendly shopping bags: As the raw material of environmentally friendly shopping bags, PP non-woven fabric has the advantages of being reusable and easy to decompose, effectively replacing traditional plastic bags.
Agricultural covering materials: such as cold-proof cloth, used to protect crops from natural disasters such as low temperature and frost, and improve the yield and quality of crops.
Medical and health care: It is widely used in medical supplies such as masks, disinfectant tapes, sanitary napkins, etc., and is favored for its non-toxic and non-irritating characteristics.
Household items: such as curtains, tablecloths, floor mats, etc., are loved by consumers for their rich colors, low prices, and easy cleaning.
Industrial packaging: In the packaging industry, PP non-woven fabrics also play an important role, used to package electronic products, food, etc.
4. Environmental advantages
PP Non-Woven Fabric has the following advantages in environmental protection:
Degradability: Its chemical structure is not strong, the molecular chain is easy to break, and it is easy to degrade, which effectively reduces the pollution to the environment.
Recyclable: PP non-woven fabric has good durability and can be reused many times, reducing resource consumption.
Non-toxic and non-irritating: It is produced using FDA-compliant food-grade raw materials, does not contain harmful substances, and is harmless to the human body and the environment.
Reduce carbon emissions: Compared with traditional materials, PP non-woven fabrics have lower carbon emissions during production and use, which helps reduce greenhouse gas emissions.
