Abstract: 본발명은리그닌을포함하는성형체를제조하기위한방법에관한것이며, 이는중간체탄소섬유그리고최종적으로또한탄소섬유로더욱가공될수 있다. 상기섬유의용도가또한개시된다. 본발명은침전욕(precipitation bath)으로의리그닌의침출문제를다룬다. 이러한문제에대한해결책은침전욕에특정염을부가하여리그닌의손실을최소화하기위한신규방법이다.

Abstract: The present invention relates to a method for manufacturing a shaped body comprising lignin which may be further processed into intermediate carbon fibers and finally also carbon fibers. Uses of said fibers are also disclosed. The present invention addresses the problem of lignin leaching into a precipitation bath. The solution to this problem is a novel method for minimizing the loss of lignin through the addition of certain salts into the precipitation bath.

Abstract: The invention relates to a method for the production of a precursor for the production of carbon- and activated carbon fibres according to the wet- or air-gap spinning method, in which a solution of lignin and a fibre-forming polymer in a suitable solvent is extruded through the holes of a spinning nozzle into a coagulation bath, the formed thread is stretched and subsequently treated, dried at an elevated temperature and then wound up. The lignin-containing thread is an economical starting material for the production of carbon- and activated carbon fibres.

Abstract: Producing a lignin-containing precursor fiber for producing carbon fibers and/or activated carbon fibers, comprises (a) providing a solution comprising at least one kind of lignin and at least one fiber-forming polymer in at least one solvent, and (b) introducing the solution into a coagulation bath by extruding through a spinneret, where the lignin precursor fiber precipitates. Independent claims are also included for: (1) the precursor fiber for producing carbon fibers comprising (in wt.%) at least one kind of lignin (10, 20-60), at least one kind of fiber-forming polymer (90, preferably 40-80), optionally a strength of at least 10 cN/tex, preferably at least 20 cN/tex, and/or optionally an modulus of elasticity of at least 1000 cN/tex, preferably at least 1300 cN/tex; (2) producing the carbon fiber, comprising stabilizing the precursor fiber at 100-400[deg] C, and carbonizing at greater than 800[deg] C under inert conditions; and (3) the carbon fiber produced by the above method.
