Abstract

Disclosed is a perforated bonded fiber fabric with a surface weight of 8- 17g/m2. The inventive fabric consists of continuous intertwined microfiber filaments with a titer that ranges from 0.05 0.40 dtex. Said filaments consi st of at least two different types of filaments made from thermoplastic polymer s with different hydrophobicities and a fiber cross section resembling the portions of a cake. The filaments are devoid of any conglutinations or fusions, especially in the region of the perforations.
