The Secret and Application of Long Spunbonded Nonwoven Fabric

In the textile industry, Long Spunbonded Nonwoven Fabric has become one of the most popular materials in recent years due to its unique characteristics and wide application fields.

Long Spunbonded Nonwoven Fabric, that is, long fiber spunbonded nonwoven fabric, is a kind of nonwoven fabric. Nonwoven fabric, also known as non-woven fabric, is a sheet, web or pad made by directional or randomly arranged fibers, which are combined with each other by friction, cohesion or bonding. Unlike traditional textile fabrics, nonwoven fabrics do not need to go through the process of spinning and weaving, so they have the advantages of short process flow, fast production speed and low cost.

Spunbonding is an important process in the production of nonwoven fabrics. In the spunbonding process, the polymer is extruded and stretched to form continuous filaments, which are then laid into a web. The web is then self-bonded, thermally bonded, chemically bonded or mechanically reinforced to eventually become a nonwoven fabric. Long Spunbonded Nonwoven Fabric has better strength and stability due to its long filament length.

Long Spunbonded Nonwoven Fabric stands out among many materials for its excellent performance. The following are its main characteristics:
High strength and stability: Long fiber spunbonded nonwoven fabric has high tensile strength and tear strength, and can maintain structural integrity under various stress conditions.
Heat resistance: Spunbonded nonwoven fabrics made of materials such as polypropylene (PP) or polyester (PET) have good high temperature resistance. Polypropylene can be used for a long time in an environment of 150℃, while polyester can maintain stable performance in an environment of 260℃.
Aging and UV resistance: This material can resist the aging effects caused by long-term light and harsh environment, and maintain its original physical and chemical properties.
Breathability and permeability: Spunbonded nonwoven fabrics have moderate breathability and permeability, making them ideal for making packaging materials, protective clothing and other products.
Environmental protection and degradability: Raw materials such as polypropylene and polyester are degradable materials, which are environmentally friendly and meet the requirements of sustainable development.

Long Spunbonded Nonwoven Fabric has been widely used in many fields due to its unique properties:
Medical and health care: Spunbonded nonwoven fabrics are widely used in the production of medical supplies such as surgical gowns, protective clothing, masks and diapers due to their good breathability and antibacterial properties.
Home decoration: In home decoration products such as wall coverings, tablecloths and bed sheets, spunbonded nonwoven fabrics are favored by consumers for their soft feel and durable properties.
Packaging materials: Due to their high strength and breathability, spunbonded nonwoven fabrics have become ideal materials for various shopping bags, storage bags and packaging bags.
Industrial applications: In civil engineering, agriculture and fisheries, spunbonded nonwoven fabrics are used as filter materials, thermal insulation curtains and crop protection fabrics.
Environmental protection field: Due to its degradability, spunbonded nonwoven fabrics are also widely used in the field of environmental protection, such as making covering films, protective films, etc. to reduce pollution to the environment.
