发明名称 PAPER AND PAPER-LIKE FIBROUS STRUCTURES FROM MIXTURES OF NATURAL, ARTIFICIAL AND SYNTHETIC FIBERS
摘要 There are disclosed paper and paper-like fibrous structures comprising natural or artificial cellulose fibers and synthetic fibers which are fibers of a propylene polymer, such as polypropylene consisting essentially of isotactic polypropylene made up of isotactic macromolecules, and having a melt index of from 0.5 to 50, said propylene polymer fibers having a length not exceeding 20 mm and a count not greater than, and preferably lower than, 2.5 dtex. The fibrous structures may also comprise a polymeric binding agent, which can be a basic condensation polymer or copolymer of epichlorhydrin with at least one member selected from the group consisting of primary and secondary aliphatic amines, aromatic amines and heterocyclic amines.
