The Secret of PET Spunbonded Machine: Technological Innovation and Wide Application

As an important equipment in the modern textile industry, PET Spunbonded Machine not only promotes the widespread application of polyester fibers, but also demonstrates its unique advantages in many fields.

PET Spunbonded Machine mainly transforms polyester chips into continuous fiber webs through a series of complex process to form non-woven fabrics. This process mainly includes the steps of pre-crystallization and drying of polyester chips, extrusion, filtration, spinning, cooling, airflow traction, mesh curtain netting, pre-reinforcement and hot rolling reinforcement.

Pre-crystallization and drying: Before entering the extruder, the polyester chips need to be pre-crystallized and dried to ensure their stability and uniformity during the extrusion process.
Extrusion and spinning: The pre-treated polyester chips are fed into the extruder, melted at high temperature and formed into continuous fibers through the spinning plate.
Cooling and airflow traction: The spun fibers are quickly cooled by the cooling device, and their continuity and directionality are maintained by the airflow traction device.
Netting and reinforcement of mesh curtain: The cooled fibers form a fiber net on the mesh curtain, and then go through pre-reinforcement and hot rolling reinforcement steps to make it have sufficient strength and stability.
PET spunbond machine has the advantages of simple process, high production efficiency, high product strength, good uniformity, and stable thermal shrinkage. In addition, with the continuous advancement of technology, the application of new equipment such as exhaust dehydration twin screw has further improved the production efficiency and product quality of PET spunbond machine.

The non-woven fabric produced by PET Spunbonded Machine has the advantages of high strength, high temperature resistance, aging resistance, UV resistance, and good air permeability, so it has been widely used in many fields.

Geotextile: PET spunbonded needle-punched geotextile has a wide range of applications in civil engineering, such as road construction, water conservancy projects, environmental protection projects, etc. Its high strength and stability make it an ideal material for reinforcing soil and preventing soil erosion.
Hygiene products: PET spunbonded non-woven fabrics are also increasingly used in the field of hygiene products, such as sanitary napkins, diapers, etc. Its soft, breathable and moisture-absorbing properties provide users with a more comfortable use experience.
Packaging materials: PET spunbond nonwovens can also be used as packaging materials, such as shopping bags, express bags, etc. Its light, environmentally friendly and reusable characteristics are in line with the green consumption concept of modern society.

PET spunbond nonwovens also play an important role in agriculture, construction, automobiles, medical and other fields. Such as sunshade nets in agriculture, sound insulation and heat insulation materials in buildings, interior materials in automobiles, etc.

With the upgrading of global consumption and the improvement of environmental awareness, PET spunbond machines are developing in a more efficient, environmentally friendly and intelligent direction. On the one hand, through technological innovation and process optimization, production efficiency and product quality are improved; on the other hand, through the introduction of intelligent equipment and Internet of Things technology, the automation and intelligent management of the production process are realized.
