PP Spunbonded Nonwoven Fabric Machines

Long spunbonded nonwoven fabric machines are an essential part of the textile industry. These machines are used to manufacture a wide range of products such as geotextiles, disposable medical products, agricultural coverings, and many more. In this article, we will dive deeper into what long spunbonded nonwoven fabric machines are and how they work.

Spunbonded nonwoven fabric is a type of fabric that is made directly from polypropylene chips or fibers using a process called extrusion. This process involves melting the polypropylene material and then extruding it through tiny holes called spinnerets to form continuous filaments. These filaments are then stretched and cooled to form a web-like structure, which is then bonded together with the help of heat or chemicals.

The long spunbonded nonwoven fabric machine is responsible for carrying out this intricate process. It consists of several key components that work together to produce high-quality nonwoven fabric.

The first component is the extruder, which is responsible for melting the polypropylene material. The polypropylene chips or fibers are fed into the extruder, where they are heated to a molten state. The molten material is then forced through the spinnerets to create the continuous filaments.

Next, the filaments are stretched and cooled using a series of rollers. This stretching process orientates the molecules of the filaments, increasing their strength and durability. The filaments are then cooled to solidify them into a web-like structure.

The bonded fabric is then subjected to a bonding process, which can be done through either thermal bonding or chemical bonding. In thermal bonding, the fabric is passed through heated calender rollers that bond the filaments together through heat. In chemical bonding, a binder is applied to the fabric, which is then cured to form a strong bond.

The final product is then wound onto rolls for further processing or packaging. The long spunbonded nonwoven fabric machine can produce nonwoven fabric with a width ranging from a few meters to several meters, depending on the specific requirements of the customer.
