Nonwoven fabrics are versatile sheet materials made from bonded or entangled fibers. SSMMS nonwoven fabric machines utilize a combination of spunbond, meltblown and spunbond processes to manufacture multi-layer nonwoven fabrics in a continuous, cost-effective manner.
The SSMMS process involves:
- Spunbond top and bottom layers – Continuous filaments are extruded and laid onto a conveyor belt to form a spunbond nonwoven web. This produces the top and bottom layers of the fabric.
- Meltblown middle layer(s) – Microfibers are extruded through fine spinnerets and deposited between the spunbond layers. This adds strength, filtration and barrier properties.
- Multi-layer bonding – The individual layers are bonded together using thermal, adhesive or ultrasonic methods to produce an integrated fabric.
SSMMS Nonwoven Fabric Machines Incorporate The Key Components Needed For Each Process:
- Filament extruders for the spunbond layers
- Microfiber extruders and spinnerets for the meltblown layers
- Spunbond and meltblown depositing units positioned above the conveyor
- Multi-layer bonding units after web formation
- Winder and rollers for winding the finished fabric
Benefits of SSMMS Nonwoven Fabric Machines:
- Continuous operation allows production of 10+ tons per day.
- Combined processes reduce infrastructure needs and optimize costs.
- Automated systems ensure uniform properties across multi-layer fabrics.
- Components are designed to withstand the stresses of industrial production.
- Machine settings can be adjusted to produce a range of nonwoven types for different applications.
