  • Method for the production of microfibrous suede-finish non-woven fabric without using organic solvents
    Patent number: 6921508
    Abstract: A method of preparation of microfibrous non-woven fabric of the suede-finish type comprising the steps of: spinning of a bi-component fiber of the “islands in the sea” type in which the “island” comprises a polymer chosen from among those employed in textile applications while the “sea” is a polymer that can dissolve and be removed by means of treatment with water, alkaline or acidic aqueous solutions, with non-polluting organic solvents alone or in aqueous solution; preparing a felt with the bi-component fiber; impregnating the felt with aqueous solution of polyvinylalcohol with reduced solubility in water; removing the “sea” component by treatment with solvents step; impregnating with emulsion or polyurethane dispersion; removing the polyvinylalcohol; and finishing the non-woven fabric obtained.
