    Abstract: 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 fibres 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.

    Abstract: A had comprising crimped bi- or multicomponent fibres consisting of at least two sections, which comprise a polymer or polymer blend as a predominant component and which are arranged across the cross-section of the fiber to promote crimping of the fibre during the setting process and which predominant components differ in. the crystallisation beat (dHc). The difference in the crystallisation heat (dHc) is in the range from 30 J/g to 5 J/g, and the predominant components differ in at least one of the other parameters selected from the group of melt flow index, degree of polydispersion and flexural modulus, while the relative difference of the predominant components is: for the flow index in the range from 100 g/10 min to 5 g/10 min and/or for the degree of polydispersion less than 1, but above 0.3, and/or for the flexural modulus in the range from 300 MPa to 50 MPa; where the relative difference in the melt flow index is not greater than 100 g/10 min, the degree of polydispersity is less than 1, the crystallisation heat is not greater than 300 Mpa. The fibres have the degree of crimping at least 5 crimps per 20 mm of fibre.
