Abstract: The present invention relates to a method for producing a textile product of the lapped/bonded type from fibers and/or filaments travelling in the direction of advance in the form of a web, this method comprising at least one step, called the “prelooping step”, in which the fibers and/or filaments individually undergo looping transversely to the direction of advance of the web, if appropriate accompanied by transverse drawing, characterized in that it subsequently comprises a step of confining the parallelized fibers and/or filaments in the form of loops, this latter confining step taking place directly on a support, without transport members, such as needles or transfer elements, being involved.

Abstract: The invention concerns a method for obtaining adequate orientation of elements constituting a web, such as fibres and/or filaments, for example derived from a card, characterized in that it consists in: subjecting the fibre to a pre-looping step produced by the interpenetration of a first set of looping discs (11) borne on a common transverse shaft (10) and continuously driven in rotation at a first speed (V1), and of a first set of fixed looping elements (12), the set of looping discs (11) and the set of looping elements (12) having a predetermined gauge (j) so as to cause the fibres and/or filaments to be pre-looped with an undulating value or interval (j), retaining with blocking means said fibres and/or filaments at regular intervals by a length (n×j) where n is an integer ranging between 2 and 20; allowing the pre-looped fibres and/or filaments to expand so as to produce large undulations having an undulating value or interval (n×j); and spreading by simple drawing the pre-looped fibres and/o

Abstract: The invention concerns a process for preparing powdery ionomers by neutralizing a powdery precursor using a neutralizing agent. A particular feature of the invention is that the precursor is used in a powder form and a concentrated aqueous solution of neutralizing agent is rapidly mixed with the precursor, and that the neutralized ionomer essentially retains the dry powder form and size of a precursor while having a water content of about 10%. The resulting product can be used as a wear layer for producing ground and wall coverings, either by powder deposition process or by extension to form a film, which is applied in a hot state to a support.
