Nonwoven fabrics of a basis weight of 10 to 30 g/m<sup>2</sup> prepared from endless filaments of 0.5 to 3.5 den of fineness by spun-melt technology primarily for producing hygienic products. It consists of endless polyolefin filaments of a volume mass in the range from 40 to 80 g/m<sup>3</sup>, its basis weight is in the range from 10 to 30 g/m<sup>2</sup> and its thickness is in the range from 0.15 to 0.80 mm, being thermally bonded on a part of its surface in the range from 10 to 16 % of its total surface area. The method for producing the nonwoven fabrics where a basic system of endless filaments of 0.5 to 3.5 den of fineness is created by spun-melt technology, which is stochastically deposited on a moving belt, of a basis weight of 10 to 30 g/m<sup>2 </sup> and then it passes through a calendering system consisting of a smooth roller and an embossed roller. |
