Spunbond nonwoven production lines are primarily used for producing nonwoven fabrics through the process of PP spinning and hot calendering reinforcement. Made mainly from PP, supplemented with color masterbatches and additives such as antioxidants, anti-pilling agents, and flame retardants, these lines produce PP spunbond hot calendered nonwovens in various colors, properties, and for different applications, widely used in medical and hygiene materials. The composite production lines, with different configurations, can produce series such as S, SS, SSS, meeting the diverse market demands for PP spunbond nonwovens from customers.
