Abstract (en)
[origin: EP0455990A1] A thermally stable, melting binder-strengthened spunbonded non-woven web composed of supporting and binding filaments in which the melting point of the binding filaments is less than 30 DEG C below that of the supporting filaments is described. The binding and supporting filaments consist preferably of polyesters. The mass per unit area of the spunbonded non-woven web is in the range between 50 and 500 g/m<2>, the elementary count of the supporting filaments and binder filaments is in the range between 1 and 20 dtex, and the proportion of the binder filaments is between 5 and 25 percent by weight. The non-woven web is distinguished by a particularly high thermal load-bearing capacity, i.e. a particularly high resistance to high subsequent treatment temperatures. It can be used, for example, as a support material for roof webs and as tufting supports etc.
