Chances and opportunities for new products applying the wet-laid process Part 3: Role of pulp in wet-laid nonwovens

摘要

For a long time now the wet-laid process has not been limited to the processing of classic cellulose pulp. In this article it is shown that high fibrillat-ed aramid pulp is capable of permanently absorbing solid material particles. The addition of specially selected substances in the processing of the pulp employed in the wet-laid process makes it possible to achieve a specific functioning of the pulp and the manufactured nonwovens made from it. Some examples of functionalization possibilities and applications are to be shown here.
