PARALLELIZATION OF STAPLE FIBERS BY ELECTROSTATIC MEANS

PROCESS FOR THE MANUFACTURE OF FILAMENTS FROM A THERMOPLASTIC MATERIAL

This invention process is concerned with a process for the manufacture of a plurality of filaments from an organic molten plastic dielectric material which has a plastic consistency such that it can be drawn into filaments while in its molten condition. This process comprises forming, on the surface of a substrate, a layer of the molten material and subjecting the material covering the substrate to the action of an electrostatic field whose lines of force extend substantially perpendicular to the surface of the substrate. Thus, under the action of the field, groups of molecules of the molten material are drawn along the lines of force to form the plurality of filaments, which start to solidify and set during movement away from the substrate.

High speed yarn prodn. - by splicing fibres into left and right rotating spun yarn ends under influence of electrostatic field

Fibres from loosened silver are fed to an electrostatic field between two rotating units which each develop a spun yarn end rotating in a left and right twist, for the fibres to be spliced in, and spun yarn is drawn off on either side of the spinning zone. A high-speed yarn output is obtd. without the fibres bunching together, and the fibres are arranged in a parallel orientation for spinning.

A process and apparatus for producing spun yarn using an electrostatic field produced by a pair of spaced electrodes, one of which surrounds the other to isolate the electrostatic field therebetween from external physical and electrical disturbances. Staple fibers are fed into the field through an aperture in the surrounding electrode for migration in the electrostatic field to a linear zone of increased field intensity from which the fibers are withdrawn and twisted to form a spun yarn, which may be done without the use of a core yarn or with a core yarn drawn through the linear zone and subjected to a false twisting operation to collect and twist the fibers thereon. Beyond the linear zone is another zone of increased field intensity for electrostatie collection of fly and other waste material. Suction is applied to remove the fly and other waste material from the electrostatic field and also serves to draw the feeding fibers through the aperture into the electrostatic field.

A machine for ringless spinning of textile fibres comprises a rotor mounted on a spindle and a passage through which fibres are fed to the rotor. The rotor is shaped like a multi vane wheel which upon rotation creates an air stream for conveying the fibres.

The invention provides a method ringless spinning with a reduced degree of "spraying of the fibres", producing a yarn with the desired linear density at increased rotor rotation speeds. The yarn spun according to this invention is cleaner than in commonly known ring spinning frames, due to the sepg. of foreign matter and the fibres as they pass through the central opening in the disc.

The polymeric nanofibers envelop the supporting linear formation (3) constituting a core (31) of the resulting linear fibrous formation (30) with a nanofibrous coating (32) composed of a flat formation created from a nanofibrous plume (6) withan organized structure of nanofibers generated by electrospinning using AC high electric voltage, whereby the nanofibrous coating (32) is wrapped around the core (31) with a helical-shaped stripe. In addition, the invention relates to a method for the production of a linear fibrous formation with a nanofibrous coating containing polymeric nanofibers, whose core is composed of a supporting linear formation (3). On a spinning electrode (5) powered by AC voltage is formed a nanofibrous plume (6), which in the spinning space (41) changes into a flat stripe with an organized structure of nanofibers, which is fed towards the circumference of the supporting linear formation (3) rotating in the spinning space around its own axis and/or ballooning in the spinning space with at least one antinode loop, whereby the stripe created from the nanofibrous plume (6) winds around the supporting linear formation, forming a helix around the supporting linear formation (3). The invention also relates to a device for producing a linear fibrous formation.
