Abstract (en)
Process for the preparation of microfibrous non-woven fabric with good mechanical and dyeing properties comprising the following stages: a) preparation of a microfiber constituted in general from polyesters used singularly or in mixtures between them or with nylons 6, nylons 6.6 or other materials normally used in the textile field; b) preparation, by means of needle-punching, of a felt comprising the microfiber indicated above; c) impregnation of the felt with polymer binder; d) mechanical treatment in order to generate the suede effect; e) dyeing of the non-woven fabric, in which a polyester constituted partially or totally from repeating monomer units of trimethylene terephthalate (PTT) of formula: <CHEM> (where n it is a number between 30 and 300) is employed as the polymer for the preparation of the microfibers that constitute the non-woven fabric <IMAGE>
