What are the methods of spunbond non-woven fabrics?

Spunbond non-woven fabric is a kind of non-woven fabric production process. It extrudes and stretches polymers to form continuous filaments. Thermal bonding, chemical bonding or mechanical reinforcement methods to turn the web into a non-woven fabric.

So what are the methods of spunbond non-woven fabrics?

The spunbond non-woven fabric separates the drawn tow into monofilaments to prevent the fibers from sticking or entangled with each other during web formation. There are three common forms of air separation, mechanical separation and electrostatic separation.

1. Spunbond non-woven air flow separation

Air flow separation is the use of aerodynamic coanda effect, the air diffuses in the fixed shape of the pipe, forming a turbulent flow to reach Separation purpose. In this way, the net is evenly laid, but the vertical and horizontal strength of the cloth varies greatly, the product has good flexibility, less filaments, no cloud spots, and high elongation.

2. Mechanical separation of spunbond non-woven fabrics

Mechanical separation is the use of mechanical devices such as baffles, pendulums, pendulum rollers, vibrating plates, and rotating guide plates. After the tow is stretched at a high speed, it encounters the impact of the mechanical device and rebounds, so as to achieve the purpose of separating the fibers from each other. Due to the large tensile force, the cloth prepared by this method has better strength and greater lateral strength, but the phenomenon of merging often occurs.

3. Electrostatic separation of spunbond non-woven fabrics

Electrostatic separation has two methods: forced electrification and triboelectric electrification.

The forced charging method is to suck the fiber bundle into an air drawing device or nozzle equipped with a high-voltage electrostatic field, so that the surface of the fiber has a high amount of charge, and the fibers with the same charge repel each other, so as to achieve purpose of splitting.

Triboelectric charging method is a method in which the tow is electrostatically charged by the friction of the friction roller before drawing, and then laid into a net after being drawn by air.
