WOVEN FURRY FABRIC AND A METHOD OF PRODUCTION THEREOF
A furry fabric includes a woven fabric having a plurality of warp and/or weft yarns extending over a number of weft or warp yarns and/or below a number of weft or warp yarns to provide over and/or under-portions having a length comprised between 8 and 3000, preferably between 25-3000. The over and under portions are at least in part cut in a garment including the furry fabric. Alternatively, the warp or weft over portions and/or the warp or weft under portions of said first yarns are not cut or broken.
HIGH-PERFORMANCE POLYETHYLENE MULTIFILAMENT YARN
Processes for making high-performance polyethylene multi-filament yarn are disclosed which include the steps of a) making a solution of ultra-high molar mass polyethylene in a solvent; b) spinning of the solution through a spinplate containing at least 5 spinholes into an air-gap to form fluid filaments, while applying a draw ratio DR.sub.fluid; c) cooling the fluid filaments to form solvent-containing gel filaments; d) removing at least partly the solvent from the filaments; and e) drawing the filaments in at least one step before, during and/or after said solvent removing, while applying a draw ratio DR.sub.solid of at least 4, wherein in step b) each spinhole comprises a contraction zone of specific dimension and a downstream zone of diameter Dn and length Dn with Ln/Dn of from 0 to at most 25, to result in a draw ratio DR.sub.fluid=DR.sub.sp*DR.sub.ag of at least 150, wherein DR.sub.sp is the draw ratio in the spinholes and DR.sub.ag is the draw ratio in the air-gap, with DR.sub.sp being greater than 1 and DR.sub.ag at least 1. High-performance polyethylene multifilament yarn, and semi-finished or end-use products containing said yarn, especially to ropes and ballistic-resistant composites, are also disclosed.

CONTINUOUS BORON NITRIDE NANOTUBE YARNS AND METHODS OF PRODUCTION
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.
