Abstract

Process for prodn. of a non-woven fabric from molten polymer comprises: (a) melt spinning the polymer(s), (b) cooling, (c) drawing the filaments, (d) laying up the fibres on a mat, (e) heat bonding the fibres by calendering to form a web, and (f) fixation treating the prod. with adjustment of the degree of crystallinity and of the internal stress of the fibres making up the non-woven fabrics. Also claimed are: (i) the nonwoven polymeric fabric; and (ii) appts. for prodn. of the nonwoven polymeric fabric.
