A process for producing a polymer strand involves: inserting a nucleation element into a pre-strand composition, the pre-strand composition comprising a polymer mixed with a solvent, the polymer having a concentration in the pre-strand composition that is greater than or equal to an overlap concentration (c*) of the polymer in the pre-strand composition; and, withdrawing the nucleation element from the pre-strand composition so that a strand comprising the polymer is pulled by the nucleation element from the pre-strand composition, the nucleation element being withdrawn at a rate such that a pull time (τ.sub.pull) of the nucleation element is less than reptation time (τ.sub.rep) required to relax polymer entanglements in the pre-strand composition, thereby inducing a viscoelastic response in the pre-strand composition as the strand is pulled by the nucleation element from the pre-strand composition.

The present disclosure relates to a process for preparing a continuous fiber filament based on a) the spreading of the fiber tow, b) the impregnation of the fiber tow in an liquid medium, comprising polymer powder particles of a certain size comprising poly(aryl ether ketone), an aqueous solvent and at least one surfactant selected from the group consisting of alkylphenoxy poly(ethyleneoxy) ethanol surfactants, c) the heating of the impregnated fiber above the melting temperature of the polymer and d) a step consisting in calendering the filaments using a die of cylindrical geometry. The present invention also relates to continuous fiber filament obtained from such process and to the use of the filaments for preparing three-dimensional objects.

An innovative high-energy oxidative method using metallic copper and chlorine liquid to produce a superior copper chloride II element using electromagnetic induction and magnetic forces. This invention involves copper undergoing oxidation while in its highest energy state according to basic principles of electromotive forces described in Faraday's law. The copper attaches to a magnetic receptacle and held in place by a copper lid cover. Research studies demonstrate that metallic copper is not magnetic; however, when a magnetic field approaches copper, the electrons and subatomic particles forms a higher resistance against the magnets—Generating a force field response towards the approaching magnets. The oxidation of copper in its highest energy state provides additional improvements and benefits in copper's antimicrobial and antiviral properties. This new method for oxidizing copper chloride in its highest subatomic energy state provides vast improvements and coverage in the fight against microorganisms and the invisible pathogens abroad.
