PET spunbonded nonwovens: a new generation of environmentally friendly and efficient multifunctional materials

PET spunbond nonwoven fabric is a kind of nonwoven fabric made of polyester (PET) resin through melt spinning process. It has many excellent features and is widely used in various fields.

PET spunbond nonwovens have the following characteristics:

Physical and chemical properties: PET spunbonded non-woven fabrics have high strength and rigidity, and at the same time have a certain degree of softness and comfort. It also has good chemical resistance and corrosion resistance, and can resist the erosion of many chemicals.

Mechanical properties: PET spunbonded non-woven fabrics have excellent mechanical properties, have high tensile strength and tear strength, and can withstand large mechanical stress and impact.

Heat resistance: PET spunbonded non-woven fabrics have good heat resistance and can maintain good performance and stability in high temperature environments.

Antibacterial property: PET spunbonded non-woven fabric has good antibacterial and mildew resistance, which can effectively inhibit the growth of bacteria and mold, making it an ideal environmental protection material.

Environmental protection: PET spunbonded non-woven fabric is an environmentally friendly material that can be recycled to reduce its impact on the environment.

The application scenarios of PET spunbond non-woven fabrics are very wide, and can be used in many fields such as medical care, hygiene, construction, electronics, and automobiles. In the medical field, PET spunbonded non-woven fabrics are widely used in surgical towels, medical bags, protective clothing, etc., providing a safer, more comfortable and hygienic environment for the medical industry. In the field of hygiene, PET spunbond nonwoven fabrics are used to make personal care products such as sanitary napkins and panty liners, which have good air permeability and antibacterial properties, and can provide better comfort and health protection. In the field of construction, PET spunbonded non-woven fabrics are used to make wallpapers, carpets, waterproof materials, etc., which have good wear resistance and corrosion resistance, and can provide more durable and environmentally friendly building materials. In the fields of electronics and automobiles, PET spunbonded non-woven fabrics are used to make insulating materials, automotive interiors, etc., which have good heat resistance and corrosion resistance, and can provide safer and more stable material protection.

The production method of PET spunbond non-woven fabric mainly includes melting polyester chips or granules and extruding them from spinneret holes to form nascent fibers, and then stretching, washing, drying and winding processes. In the production process, it is necessary to select appropriate equipment, such as melt extruders, stretching machines, and winding machines, to ensure the quality and performance of PET spunbond nonwovens.

In general, PET spunbonded nonwoven fabric is a new material with excellent performance and wide application, and its application prospect and market potential are huge. With the continuous improvement of environmental protection awareness and the continuous improvement of technical level, PET spunbonded non-woven fabrics will be applied and developed in more fields.
