PET Nonwoven Fabric: A combination of high strength and versatility

PET Nonwoven Fabric, also known as polyester spunbond nonwoven fabric, is a nonwoven fabric made of polyester chips. It is made by melting the polyester chips and then stretching them in a directional manner, and spraying adhesive during the stretching process to make the fibers bond to each other to form a sheet or roll of fabric. PET nonwoven fabric has been widely used in many fields due to its high strength, high temperature resistance, aging resistance, UV resistance, corrosion resistance and other properties.

The production process of PET nonwoven fabric includes the production of polyester chips, melt extrusion, fiber formation, fiber cooling and stretching, fiber cutting and winding, and finished product inspection and packaging. The quality of polyester chips has an important influence on the performance and quality of PET nonwoven fabrics, so it is necessary to strictly control the molecular weight, viscosity, crystallinity and other parameters of the chips. During the melt extrusion process, it is necessary to control the temperature, pressure and screw speed to ensure the uniformity and stability of the melt. The fiber formation, cooling and stretching process determines the fiber properties, such as strength, elastic modulus, etc.

In terms of production technology, PET non-woven fabrics can use different processes, such as spunbond hot rolling, spunlace, needle punching, etc., to meet the needs of different fields. Spunbond hot rolling process is one of the main production processes of PET non-woven fabrics, which gives non-woven fabrics high strength, temperature resistance, corrosion resistance and other characteristics. The spunlace process uses high-pressure micro-water jets to entangle the fibers with each other, which is suitable for producing soft and breathable non-woven fabrics.

PET non-woven fabrics have a wide range of applications, covering medical, health, home decoration, clothing, industry, agriculture and military. In the medical field, PET non-woven fabrics are used to make medical supplies such as surgical gowns, protective clothing, disinfection wraps, masks, etc. Its antibacterial, good breathability and easy disinfection make it an ideal choice for the medical industry. In the field of home decoration, PET non-woven fabrics can be used to make carpets, wall coverings, curtains, etc. Its beautiful, durable and easy-to-clean characteristics are deeply loved by consumers.

In the industrial field, PET non-woven fabrics are widely used in automobile roof cloths, filter materials, insulation materials, cement packaging bags, etc. Its high strength, corrosion resistance, and temperature resistance make it a preferred material for industrial production. In the agricultural field, PET non-woven fabrics are used for crop protection fabrics, seedling cloths, etc. Its lightness and durability help improve agricultural production efficiency.

With the improvement of global environmental awareness, the environmental performance of PET non-woven fabrics has also received increasing attention. PET non-woven fabrics have a high recycling rate and can reduce pollution to the environment. In the production process, the environmental pollution in the production process can be effectively reduced by using biological treatment, activated carbon adsorption, membrane separation and other technologies to treat wastewater, as well as recycling and reusing waste PET chips and waste scraps. The production process of PET non-woven fabrics is relatively energy-saving, and its energy consumption is lower than that of traditional textile production. This gives PET non-woven fabrics significant advantages in environmental protection and sustainable development.
