A method of forming a thermally bonded, nonwoven polypropylene fabric is provided and includes passing a web of thermally bondable skin-core polypropylene fibers through a calender nip under heat and pressure to produce a nonwoven fabric having elongation. The patterned calender roll is embossed with a plurality of spaced and staggered lands particularly dimensioned, configured and oriented to provide the desired bonding spot size and spacing between the bonding spots such that when utilized in the calender roll, an improved soft polypropylene fabric or cover sheet having a high elongation results.

L'invention a trait à un procédé de formage d'un tissu non tissé en polypropylène thermolié et consistant à faire passer une bande de fibres de polypropylène à peau-âme thermoliable par le point de pinçage d'une calandre à chaud et sous pression pour produire un tissu non tissé présentant un allongement. Le rouleau de calandre dessiné est gaufré par une pluralité de crêtes espacées et zigzaguées dimensionnées, configurées et orientées de façon particulière pour former la taille des points de liage et l'écartement voulu entre les points de liage de manière que lorsqu'ils sont utilisés dans le rouleau de calandre, on puisse obtenir un tissu ou une feuille de couverture en propylène souple amélioré ayant un degré élevé d'allongement.
