A nonwoven web comprising heat bondable fibres and comprising bonding impressions that form a pattern repeated in the machine direction (MD), wherein the bonding impressions include: a system of basic bonding impressions, which are arranged to create visually primary patterns and an area of each basic impression is at least 1 mm, and a system of auxiliary bonding impressions having the area smaller than 1 mm, and wherein a sum of bonding areas of the individual auxiliary bonding impressions accounts for at least 30% of a total bonding area.

A method of producing nonwoven textile by a spunmelt process of a polymer, the basis of which is at least one polyolefin, comprising a barrier and antistatic treatment, especially for protective garments for industry and health care. A polyolefin polymer which is suitable for forming fibers is mixed with a first additive capable of modifying a surface property and capable of migration through the polymer, then the mixture is used for producing at least one layer of the nonwoven textile by a spun-melt process, and prior to the termination of the migration of the first additive and to the stabilizing of the final barrier properties on the surface of the fibers a second additive is applied to the layer, the second additive being capable of modifying the antistatic property of the material, and then the nonwoven textile is exposed to a temperature and relative humidity conditions for a time period such that the first additive migrates towards the surface and the second additive undergoes changes on said surface.
