A hybrid fiber which includes: a metal wire having a roughened surface; and a fiber is provided. In the hybrid fiber, the metal wire and the fiber are combined.

A method and apparatus for producing boron nitride nanotubes and continuous boron nitride nanotube yarn or tapes is provided. The apparatus includes rotating reaction tubes that allow for continuous chemical vapor deposition of boron nitride nanotubes. The rotation of the reaction tubes allows the boron nitride nanotubes to be spun into yarns or made into tapes, without post process or external rotation or spinning of the gathered nanotubes. Boron nitride nanotube yarns or tapes of great length can be produced as a result, thereby providing industry with a readily useable format for this type of material. Dopants such as carbon can be added to engineer the band gap of the nanotubes. Catalysts may be formed outside or inside the reactor.

Apparatuses and associated methods of manufacturing are described that provide for cut-resistant yarn structures. An example cut-resistant yarn structure includes a first cut-resistant core filament a second cut-resistant core filament. The yarn structure further includes a first covering yarn that is wound over the first cut-resistant core filament and the second cut-resistant core filament. The first covering yarn includes a core-spun yarn in which staple fibers are spun over a third cut-resistant core filament. The yarn structure also includes one or more covering layers wound over the first covering yarn that may serve as the exterior layer for the cut-resistant yarn structure. In some instances, the first and second cut-resistant core filaments include a core-spun yarn in which staple fibers are spun over the first cut-resistant core filament and/or the second cut-resistant core filament.

Twisted, non-blended hybrid yarns are provided that are suitable for the fabrication of abrasion resistant garments and other textile articles. One or more polyolefin fibers are ply twisted together with one or more non-polyolefin fibers in a manner that utilizes the properties of each fiber type. A plurality of the twisted, non-blended hybrid yarns is then woven or knitted into fabrics, such as twill woven denim, or formed into ropes, such as braided ropes.

Disclosed is the preparation of improved high strength nylon staple fibers having a denier per filament of 1.0 to 3.0, a tenacity T at break of at least about 6.0, and a load-bearing capacity, T.sub.7, of greater than 3.2. Such nylon staple fibers are produced by preparing tows of relatively uniformly spun and quenched nylon filaments, drawing and annealing such tows via a two-stage drawing and annealing operation using relatively high draw ratios and then cutting or otherwise converting the drawn and annealed tows into the desired high strength nylon staple fibers. The nylon staple fibers so prepared can be blended with other fibers such as cotton staple fibers to produce nylon/cotton (NYCO) yarns which are also of desirably high strength.

The present disclosure provides a knitting apparatus, including: a frame; a primary yarn guide mounted on the frame; a primary yarn control rod connected to the primary yarn guide; a secondary yarn guide mounted on the frame; a secondary yarn control rod connected to the secondary yarn guide; a needle plate provided at lower ends of the primary yarn guide and the secondary yarn guide; a control cam separately drives the primary yarn control rod to control the primary yarn guide to move, and drives the secondary yarn control rod to control the secondary yarn guide to move; a tension spring connected to the control cam; and an electromagnet. A magnetic force of the electromagnet drives the tension spring to extend and retract, and further drives the control cam to rotate up and down.

A protective glove includes a primary yarn that forms the palm, thumb and finger sections of the glove. The primary yarn has an interior surface forming the interior surface of the glove, and an exterior surface forming the exterior surface of the glove. A plaiting yarn can be plaited to portions of the exterior surface of the primary yarn to form a plurality of enhanced sections on the exterior surface of the glove. The enhanced sections can have at least one substantially enhanced physical characteristic in relation to the primary layer.

A three-dimensional, 3D, knitted fabric is knitted by a double-bed weft-knitting machine. The knitted fabric comprises a top layer, a bottom layer, and an intermediate layer, wherein the top layer and the bottom layer are joined together by cross-yarns constituting the intermediate layer, and wherein at least the top layer comprises two-folded cut-resistant yarns.
