spunbond fabric

The spunbond method (Spunbond) is melt spinning to form a web, which is to heat and melt the polymer, and extrude the melt from the spinning hole into the air through the extruder. Stretching at a certain speed becomes thinner and longer (airflow or mechanical action), and at this stage, the polymer melt is refined and solidified at the same time, thereby forming fibers and then forming a network. Spunbond fabric is also called filament nonwoven fabric. Its key technologies are spinning, stretching, web laying and web forming. From this point of view, spunbond method is an integration of chemical, plastic, papermaking, chemical fiber and other industries. Comprehensive technology involving many disciplines. From the perspective of industry ownership, although spunbond fabric belongs to a branch of the textile industry, it has become a relatively independent and vigorous production industry; at the same time, since spunbond fabric is mainly made of polypropylene chips or polyester chips directly into the net Therefore, it is also closely related to the fields of petrochemical and emerging materials industries.
