摘要： A method of manufacturing a wet-laid nonwoven web includes the following steps: feeding a pulp suspension onto a forming screen for depositing a fibrous web thereon, wherein the pulp suspension has industrially produced, inorganic fibers or fibers of synthetically produced polymers and the pulp suspension is substantially free from binders, such as chemical binders, and hydraulic consolidation of the fibrous web to generate the nonwoven web through water jet needling of the fibrous web.
