CA 2369349

A spunbonded non-woven fabric comprising a fiber containing a polypropylene resin as a main component, which has a fiber diameter of 0.8 to 2.8 denier, an average coefficient of friction (MIU) of 0.1 to 0.3, a thickness uniformity of 0.8 or less, a water resistance of 60 mm H2O or more and an air permeability of 480 ml/cm2/sec or less; and a laminate comprising the spunbonded non-woven fabric and, laminated thereon, a melt-blown non-woven fabric. Such a spunbonded non-woven fabric shows no surface roughening and gives an excellent and agreeable touch, due to its finer fiber diameter which has achieved according to the present invention, as well as reduced feeling of stickiness. Further, the spunbonded non-woven fabric can be produced with efficiency without yarn breaking.

L'invention concerne un textile non tissé filé-lié comprenant une fibre contenant une résine polypropylène comme composant principal, possédant un diamètre de fibre de 0,8 à 2,8 deniers, un coefficient de frottement moyen (MIU) de 0,1 à 0,3, une homogénéité d'épaisseur de 0,8 ou moins, une résistance à l'eau de 60 mm H¿2?O ou plus et une perméabilité à l'air de 480 ml/cm?2¿/s ou moins. L'invention porte également sur un stratifié comportant le textile non tissé filé-lié et, contre-collé sur ce dernier, un textile non tissé de fusion-soufflage. Ledit textile non-tissé filé-lié ne présente pas de rugosité de surface, est agréable au toucher en raison du diamètre des fibres inférieur et procure une sensation de collant moindre au toucher. Par ailleurs, le textile non tissé filé-lié peut être produit efficacement sans rupture de fil.
