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.

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.

Meltblown yarn and method and apparatus for manufacturing

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.

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.
