A composite fiber comprising an array of inorganic nanowires embedded in a polymer matrix. The nanowires have a diameter <100 nm and high aspect ratio of at least 5 with homogenous dispersion and polymer chains of the polymer matrix and the nanowires are oriented along the fiber axis. The nanowire wt % in the composite fiber is in the range of 0.01 to 2 wt %. The inorganic nanowires are non conducting and include at least one of ZnO, or aluminosilicate clay tubes.

An elastic multiple component fiber comprising a cross-section, wherein at least a first region of said cross-section comprises a polyurethaneurea composition; and comprising a second region.

Included are multiple component elastic fibers prepared by a solution-spinning process such as dry spinning or wet spinner of spandex fibers including polyurethaneurea and polyurethane compositions. These fibers have a cross-section including at least two separate regions with definable boundaries wherein at least one region defined by the boundaries of the cross-section includes a polyurethaneurea or polyurethane composition. One region of the fiber includes a fusibility improvement additive to enhance adhesion to itself or to a substrate.

A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a matrix of a first base polymer and particles dispersed within the matrix, and a shell portion comprising a same or a different base polymer. The consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional part, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament and retain the particles within the roads of the printed part and do not penetrate the outer surface of the shell portion.

A nonwoven fabric comprising a meltspun fiber of a lignin compound. Also claimed a laminated fabric comprising the nonwoven fabric, a nonwoven fabric product comprising the nonwoven fabric, a structured multicomponent fiber comprising a lignin compound, a web comprising a meltspun fiber of a lignin compound and a method of producing a nonwoven fabric by forming a web of meltspun fiber comprising a lignin compound and bonding at least a portion of the fiber in the web to form the nonwoven fabric.

A macro fiber for a composite article may include a plurality of inner fibers. Each one of the inner fibers may have an inner fiber final cross-sectional size of less than approximately 100 nanometers. The inner fibers may be surrounded by matrix material.

An apparel textile yarn includes a polyamide. The polyamide includes a nylon and a polyetheramine. The polyetheramine has a molecular weight of at least 1500 and an Amine Hydrogen Equivalent Weight (AHEW) of less than 10 percent higher than the idealized AHEW for the polyetheramine. The polyamide may have a moisture regain ranging from about 10% to about 30%.

An additive three-dimensional fabrication system includes voice control for user interaction. This voice-controlled interface can enable a variety of voice-controlled functions and operations, while supporting interactions specific to consumer-oriented fabrication processes.

A method for producing a fiber preform or semi-finished textile product comprises providing a fiber preform or semi-finished textile product comprising at least one thermoplastic fiber. The thermoplastic fiber has a core constructed of a first material, a shell constructed of a second material positioned to surround the core, and magnetic particles that are one of mainly arranged in the shell, almost exclusively arranged in the shell, and exclusively arranged in the shell. Continually adding the fiber preform or semi-finished textile product with simultaneous heating thereof in continuous passing through or passing by a magnetic induction heating device or the same by way of a relative movement. Fixing the fiber preform or semi-finished textile product by allowing the fiber preform or semi-finished textile product to rigidify.
