    摘要： The present invention concerns a process for preparing a microfibrous multilayer composite material comprising: 1) realizing a non-woven microfibrous semi-finished product made up of microfibres of one or more polymers dispersed in a polyurethane matrix (semi-finished product IE); 2) cutting the semi-finished product lengthwise into two layers; 3) buffing at least one layer on one side (side N) so as to extract the microfibres and form the nap, thereby obtaining a semi-finished raw product; 4) cutting at least one semi-finished raw product lengthwise parallel to the surfaces, producing an non-woven intermediate product, containing the buffed side (side N) and a waste layer (containing the side that has not been buffed—side S); 5) coupling the non-woven intermediate product (on the side opposite side N) to a fabric made of polyethylene terephthalate fibres by means of the application of a thermoplastic polyurethane adhesive that can be cross-linked between the non-woven intermediate product and the fabric; 6) submitting the multilayer composite material to a jet dyeing process. The invention also concerns a multilayer composite material that can be obtained by the process of the invention and the use thereof for covering the internal side of roofs or headliners of vehicles and for covering furnishing elements.

    摘要： The present invention refers to a process for the preparation of a non-woven microfibrous suede-like synthetic fabric that does not require the use of organic solvents and that makes it possible to obtain a finished product offering a good hand, excellent resistance to yellowing and high durability. It comprises needle-punching a felt of sea/island fibers, (a) impregnation with hot aqueous solution of PVOH having a degree of saponification of at least 94% or (b) impregnation with hot water followed by impregnation with cold PUR, removing the sea component, impregnating with PUR, coagulating the PUR, removing the PVOH, grinding the surface, dyeing and splitting in two sheets.
