摘要

Process for pre-strengthening a non-woven textile fibre fleece obtained by the wet process wherein a heat-sensitive latex mixture whose coagulation point does not substantially change on dilution is applied in a finely divided form to the surface of the wet fleece and the fleece is then heated to a temperature at which the latex mixture coagulates to form a gel-like film.
