Understand How PP Spunbond Nonwoven Fabric is Made on Making Machines

PP spunbonded (polypropylene spunbonded) nonwoven fabric is widely used in various industries for its functionality and quality. The pp spunbond nonwoven fabric making machine continuously produces PP spunbond nonwoven fabrics in large quantities.

pp Spunbond Nonwoven Fabric Making Machine

PP spunbond nonwoven fabric is made through a process known as spunbonding. This involves melting polymer filaments and extruding them through tiny spinneret holes into fine fibers. As the fibers exit the spinneret, a flow of air carries the fibers to form a random web on a collection belt.

The pp spunbond nonwoven fabric making machine controls every step of this process with precision to produce consistent fabrics. The main parts of the machine include:

  • Filament extruder – Melts and extrudes the PP polymer into fine filaments
  • Spinneret – Contains multiple holes that form the filaments into fibers
  • Winding unit – Winds up the finished nonwoven fabric for rolling
  • Air supply system – Provides airflow to randomly deposit fibers onto the belt

Process By PP Spunbond Nonwoven Fabric Making Machine

During production, the machine heats and feeds the PP pellets into the extruder at a constant rate. The extruder melts the polymer and forces it through the spinneret holes. Hot air blows the fibers onto the moving belt to create a web.

The machine then compacts and consolidates the web through processes like needle punching and thermal bonding. This fuses the fibers together to give the fabric strength and stability.

PP Spunbond Nonwoven Fabric Has Many Applications Thanks To Its Characteristics:

  • High strength and durability
  • Good moisture absorption
  • Superior oil and chemical resistance
  • Excellent barrier properties
  • Wide range of basis weights

Some Common Uses Of PP Spunbond Nonwoven Include:

  • Hygiene products like diapers and feminine pads
  • Lawn and garden supplies like weed barrier fabrics
  • Filters for air, liquids and gases
  • Medical products like drapes and gowns
