The spunmelt process used in the production of PP SMS nonwoven fabric is just one of several china nonwoven fabric line supplier manufacturing processes. Here’s how it compares to some other common nonwoven fabric manufacturing processes:
Needle punching
Needle punching is a nonwoven fabric manufacturing process that involves entangling fibers together using barbed needles. This process is commonly used to produce felt-like fabrics, such as those used for carpet padding or insulation. The resulting fabric is typically less smooth and uniform than spunmelt fabrics.
Wet-laid
Wet-laid nonwoven fabric manufacturing involves suspending fibers in water or other liquids and then depositing them onto a moving belt or drum. The fabric is then bonded using heat or other methods. Wet-laid nonwoven fabrics tend to be softer and more absorbent than spunmelt fabrics, but they are also typically less durable.
Air-laid
Air-laid nonwoven fabric manufacturing uses a similar process to wet-laid, but the fibers are suspended in air instead of water. The fibers are then collected on a moving belt or drum and bonded together using heat or other methods. The resulting fabric is typically softer and more absorbent than spunmelt fabrics, but it is also less durable.
Compared to these other nonwoven fabric manufacturing processes, the spunmelt process used in the production of PP SMS nonwoven fabric tends to produce a stronger, more durable fabric that is also more uniform and consistent in its properties. The spunmelt process is also more efficient and cost-effective than some other methods, as it does not require the use of water or other liquids and can be performed at high speeds with relatively low energy consumption.
