The machinery is suitable for the production of nonwoven fabric by spunbonded and hot-calendered reinforcement.
It uses pp as its main material; color master batch, antioxidant, fire retardant as its additives to produce nonwoven fabric with different colors and different elements to fit the needs of different usages.
This machine is able to produce ssmm spun-melting nonwoven fabric, smms spun-melting nonwoven fabric, sms spun-melting nonwoven fabric, sss spunbonded nonwoven fabric, ss spunbonded nonwoven fabric, and m melt blown nonwoven fabric.
