Spunbonded non-woven fabric refers to non-woven fabric produced using the spunbonded process, also known as melt blown fabric. The production process of this non-woven fabric is to melt or dissolve the polymer, spray it into a fine wire state through a spinneret, then wind it into a network structure, and then process it into shape through chemical treatment and heating curing. Its characteristics include good strength, breathability, water resistance, filtration, and flame retardancy. Spunbonded non-woven fabrics are widely used in various fields such as healthcare, filtration, building isolation, and automobiles.
The production principle of spunbonded non-woven fabric is to melt or dissolve the polymer first, and then spray it out through a spinneret to form a fine filament state. These fine filaments are cooled and solidified to form a fiber network structure, and then processed and formed through processes such as chemical treatment and heating solidification to produce non-woven fabric. The process of making this non-woven fabric has the following main characteristics:
1. Spinning process: In the spinneret, melted or dissolved polymers are sprayed out under corresponding pressure to form long and fine filaments.
2. Continuous forming: After cooling and solidification, the fine wires are wound and stacked on rubber rollers or adsorbers to form a continuous network structure.
3. Chemical treatment: introduce chemicals to make the filaments gel, and then heat them to form a firm network structure.
4. Processing and forming: By cutting, merging, and other processes, spunbonded non-woven fabrics are processed and formed to produce various types of non-woven fabric products with different specifications and purposes.
In summary, the production principle of spunbonded non-woven fabrics adopts modern chemical technology and mechanical processes. With its efficient and flexible production methods, high-quality, high-performance, and widely used non-woven fabric products can be produced.
