Here’s how PE/PP skin-core type bicomponent spunbond nonwoven fabric is typically produced:

  1. Polymer Preparation: The PE and PP polymers are separately melted and prepared for extrusion.
  2. Spinning: The molten polymers are extruded through a bicomponent spinneret that forms continuous filaments with a PP core and a PE skin.
  3. Web Formation: The bicomponent filaments are laid down randomly to form a nonwoven web.
  4. Bonding: The web is bonded using thermal bonding techniques, leveraging the different melting points of PE and PP to create a strong, cohesive fabric.
  5. Finishing: The fabric is treated and finished according to the specific requirements of its intended application, such as adding additional treatments for softness, hydrophilicity, or other desired properties.

key Characteristics

  1. Enhanced Strength and Durability: The PP core provides excellent tensile strength and structural integrity, making the fabric durable and resistant to tearing and stretching.
  2. Softness and Comfort: The PE skin contributes to the fabric’s softness, making it comfortable for applications that involve direct contact with the skin.
  3. Good Barrier Properties: The combination of PE and PP offers effective barrier properties against fluids and particulates, enhancing protection.
  4. Chemical Resistance: Both PE and PP are resistant to a wide range of chemicals, making the fabric suitable for use in various industrial and medical applications.
  5. Breathability: The fabric can be designed to allow air and moisture vapor to pass through, providing breathability while maintaining barrier properties.
  6. Thermal Bonding Capability: The different melting points of PE and PP allow for efficient thermal bonding during the manufacturing process, ensuring strong cohesion between the layers.
  7. Cost-Effectiveness: By using a combination of PE and PP, manufacturers can optimize the material properties and reduce costs compared to using pure polymers.
