Abstract: The invention relates to a linear fibre formation comprising nanofibres deposited on a linear fibre core, at the same time the nanofibres are to the core fixed with a coil of at least one covering thread. The invention further relates to a method and a device for production of a linear fibre formation comprising a linear fibre core, on which in a spinning space of an electric field of high intensity the nanofibres produced through electrostatic spinning of polymer matrix are deposited. Through the spinning space of the electric field at least two straight segments of the linear fibre core are guided, between which the core outside the spinning space of electric field is guided at least along a section of circumference of the guiding cylinder, while in projection into a plane being tangential to circumference of the guiding cylinder and passing the respective segment of the core, this segment of the core and longitudinal axis of the guiding cylinder contain an acute angle.

Abstract: Production method of layered sound absorptive non-woven fabric, which comprises a resonance membrane which is positioned between two layers of the card fibrous web, while both layers of the card fibrous web are produced simultaneously in carding machine, from which each layer of the card fibrous web is separately brought into the device for production of nanofibres through electrostatic spinning, in which to the side of at least one layer of the card fibrous web adjacent to the remaining layer of the card fibrous web a layer of nanofibres is applied, after then both layers of the card fibrous web near to one another until their adjacent sides sit down one on another, they are laid one on another in a selected quantity of layers and the layers join mutually.

Abstract: A method of nanofibers production from a polymer solution uses electrostatic spinning in an electric field created by a potential difference between a charged electrode and a counter electrode. The polymer solution for spinning is supplied into the electric field using the surface of a rotating charged electrode. On a part of the circumference of the charged electrode near to the counter electrode, a spinning surface is created for attaining a high spinning capacity. In a device for carrying out the method, the charged electrode is pivoted and part of its circumference is immersed in the polymer solution. The free part of the circumference of the charged electrode is positioned opposite the counter electrode.

Abstract: The invention relates to the cigarette filter containing the microfibres, which contains from 0.5 to 10% by weight of polymeric nanofibres, that are arranged among the microfibres. At manufacturing of cigarette filter containing the microfibres, the nanofibres or shreds of surface nanofibrous textile are brought to the surface of a configuration designated for production of the cigarette filter formed at least of 90% by weight of microfibres, and they are deposited onto the surface and/or into the volume of the configuration in a quantity from 0.5 to 10% b weight.

Abstract: The invention relates to the textile containing at least one layer of polymeric nanofibres having diameter to 600 nanometres produced through electrostatic spinning of the polymer solution. The polymeric nanofibres contain particles of low-molecular substance dissolved or dispersed in solution of polymer which is subject to electrostatic spinning, possibly particles of low molecular substance which was created through a consequent chemical reaction of the original low molecular substance dissolved or dispersed in solution subjected to electrostatic spinning.

Abstract: The invention relates to the layered sound absorptive non-woven fabric containing the resonance membrane and at least one another layer (1, 3) of the fibrous material at which the resonance membrane is created by a layer (2) of nanofibres having diameter to 600 nanometers and of surface weight 0.1 to 5 g/m2, at the same time the resonance membrane together with at least one layer (1, 3) of fibrous material is formed by cross laying to the required thickness and surface weight.

Abstract: The invention relates to a method of nanofibres production from a polymer solution using electrostatic spinning in an electric field created by a potential difference between a charged electrode and a counter electrode. The polymer solution (2) is for spinning supplied into the electric field using the surface of the rotating charged electrode (30), while on a part of the circumference of the charged electrode (30) near to the counter electrode (40) is a spinning surface created, by which is a high spinning capacity reached. Further the invention relates to a device for carrying out the method, where the charged electrode (30) is pivoted and by its (bottom) part of its circumference it is immersed in the polymer solution (2), while against the free part of the circumference of the charged electrode (30) is positioned the counter electrode (40).

Abstract: A yarn of meltblown thermoplastic fibers is manufactured by meltblowing fibers onto a collector to form a thin web thereon, and continuously withdrawing and twisting the web into a generally circular yarn. In a preferred embodiment the yarn has a reinforcing cord disposed therein to lend strength thereto. The yarn is suited for many applications, including knitted and woven fabrics, and cartridge filters.

Abstract: A web or film is electrostatically charged by sequentially subjecting the web or film to a series of electric fields such that adjacent electric fields have substantially opposite polarities. Both a method and apparatus are disclosed for charging the web or film.

Abstract: A staple fiber web is disclosed which contains pleats having staple fibers which are commingled with staple fibers from adjoining pleats. The commingling permits denser packing of pleats on the web and increases filtering efficiency and stability of the web. Methods of manufacturing the pleated staple fiber web are disclosed.
