Abstract (en)
[origin: EP0601277A1] A method and apparatus for producing a textile fabric in which at least two melts of at least two polymer materials are converted to the shape of threads (2) with the aid of a spinning device, and in which the threads (2) are subsequently united and bonded. The spinning device consists of a spinning centrifuge (1), and the polymer materials have an electrical differential potential of at least 10 charge units. The two materials are melted on separately from one another and, because of a distributor device (3), each melt is fed in each case to a group of outlet apertures (4) of the spinning centrifuge (1) without having been mixed. The threads (2) emerging from the outlet apertures (4) are firstly stretched and united to form a common fabric, the fabric subsequently being charged triboelectrically by an aftertreatment process. <IMAGE>
