Abstract

1. Process for producing an imitation leather web, in which a web is formed by dry joining together of fibres and its structure is densified by needle-punching and by activation of shrinkage forces, a binder having a coagulable composition and possessing an aqueous carrier liquid is introduced and the web is subsequently exposed to the action of an acidified liquid, dried and subjected to a finishing treatment, characterised in that the web is formed of hydrophobic fibres having a gauge of less than 2 dtex and is densified by needle-punching and shrinking to a density of 0.15 to 0.45 g/cm**3 , that an elastomeric binder is used and that, together with the latter, pulverulent barium sulphate and a further substance are introduced and uniformly distributed in the web from which a gas is evolved under the action of the liquid which has been acidified and heated to a temperature above the coagulation temperature of the binder, while the binder coagulates, and that after the binder has solidified the web is washed, dried and, to produce its pile, is buffed on at least one fleece and subsequently intensively milled.
