The Production Process Of Pp Spunbond Non-woven Fabric?

Raw material, which is polypropylene (PP) pellets. The PP pellets are typically melted and extruded into filaments that are later spun into fabric. 2. Extrusion: The melted PP pellets are extruded through spinneret nozzles to form filaments. These filaments are stretched and then cooled by a cooling fan. 3. Spinning: The filaments are spun into a uniform web on a moving belt or conveyor. The spun web is then bonded by thermal or chemical processes to create a non-woven fabric. 4. Bonding: There are several methods used for bonding PP spunbond non-woven fabrics, including thermal bonding, needle punching, and chemical bonding. Thermal bonding involves heating the web to create a bond, while needle punching involves mechanically bonding the web with needles. Chemical bonding involves applying a bonding agent to the web and then curing it. 5. Finishing: After bonding, the non-woven fabric is treated with finishing agents to improve its properties such as UV resistance, water resistance, and colorfastness. The fabric is then cut into rolls or sheets and packaged for shipping or further processing. Overall, the production process of PP spunbond non-woven fabric is relatively simple and cost-effective, making it a popular choice for a wide range of applications, including in the medical industry, agriculture, and construction
