Spunbonding is a process by which fabrics are produced directly from a thermoplastic polymer such as polyester, nylon, polypropylene, or polyethylene. The molten polymer is extruded through a spinneret, cooled slightly in the air, and laid on a moving conveyor belt to form a continuous web. As the web cools, the fibers bond. 

Spunbonding method is used for man-made filament fibers that melt under heat, such as polyester. Spunbond fabrics are produced by depositing extruded, spun filaments onto a collecting belt in a uniform random manner followed by bonding the fibers. Spunbond fabrics are characterized by tensile, tear, and burst strengths, elongation-to-break, weight, thickness, porosity and stability to heat and chemicals. Spunbond products are employed in carpet backing, geotextiles, and disposable medical/hygiene products. Since the fabric production is combined with fiber production, the process is generally more economical than when using staple fiber to make nonwoven fabrics.

Spunbonded fabrics are strong because of the filament fibres and are not easily torn. They are used for a wide variety of products ranging from apparel interlinings, carpet backing, furniture and bedding to bagging and packing material. Spunbonded fabrics may be used in geotextile to control erosion or in constructing road. Some spunbonds made from olefins are used as a tough, especially durable substitute for paper in wall coverings, charts, maps, tags and the like.
