Method of bonding a web of fibers or filaments by entangling them by using high-pressure water jets. A preformed web is entangled by means of high pressure, columnar water jets. As the jets penetrate the web, fiber segments are carried by the highly turbulent fluid and become entangled. In addition to bonding the web, which needs little or no additional binder, the process can also be used to impart a pattern to the web. Also referred to as SPUNLACING.
