Non-woven af spunbonded termoplastiske filamenter med forbedrede svejseegenskaber samt fremgangsmåde til fremstilling af en sådan non-woven

摘要

The non-woven fabric of spunbonded thermoplastic filaments comprises 95 mass% of its surface mass (g/m 2>) of two polypropylene A and B polymers. The filaments have a titer of 0.5-1.1 dtex. The non-woven fabric has a surface mass of 10-25 g/m 2> and a welding rate of 10-25%. The non-woven fabric comprises 93 mass% of its surface mass of the polypropylene A polymer obtained by polymerization in the presence of a polymerization catalyst based on metallocene and 12 mass% of its surface mass of the polypropylene B polymer. The non-woven fabric comprises 9.5 km of filaments per m 2>. Independent claims are included for: (1) a hygiene article; and (2) a method for manufacturing the non-woven fabric.
