| 摘要 |
The object of the present disclosure is a non-woven of spunbonded thermoplastic filaments comprising in a characteristic way, at least 95% by mass (g) of its surface mass (g/m2) of at least two polypropylene A and B polymers, said filaments having a titer of less than or equal to 1.3 dtex, said non-woven having a surface mass of less than or equal to 35 g/m2, the welding rate being at least 10% and at most 25% and at least 88% by mass (g) of its surface mass (g/m2) of said polypropylene A polymer obtained by polymerization in the presence of at least one polymerization catalyst based on a metallocene and at most 12% by mass (g) of its surface mass of said polypropylene B polymer. |
