[0003] The principle of reinforcing the fiber web by the spunlace method is similar to the needle punching process, but instead of needles, a plurality of fine water jets generated by high pressure are used to spray the fiber web. After the water jets pass through the fiber web, they are bounced by the holding screen and then penetrate the fiber web again. As a result, the fibers in the fiber web are displaced, penetrated, entangled and bonded under the hydraulic action of the high-speed water jets penetrating in different directions, so that the fiber web is reinforced.
