And methods of plant dry produce a non-woven fibrous web of long fibers, cotton linter cotton fiber web comprising (CLP) and short fibers

摘要

A plant that includes two air-lay stations placed one after the other serving for the dry production of a non-woven fiber web. Each station includes a fiber feed duct for feeding fibers to the station from a fiber source, an air-lay forming head connected to the fiber feed duct and at least partly defined by a perforated screen, and a suction box for successively sucking fibers in the forming head through the screen. A separate fiber source is part of each station. The first station furthermore has a fiber collector placed under the screen of its forming head whereas the second station has a forming wire placed under the screen of its forming head. The two stations are connected to at least one conveyor for conveying fibers from the fiber collector of the first station to the forming head of the second station. By means of the plant, a cotton fiber web on the basis of Cotton Linters Pulp and thermobinding fibers can be produced which, considering its quality, are price competitive with corresponding fiber webs based on cellulose pulp. This cotton fiber web has a homogenous, nit-free structure which is desirable for use in various products.
