The mixture is heated and the solid polymer material is at least partially dissolved within the carrier fluid having the carbon powder suspended therein. The carrier fluid is removed from the mixture, forming the polymer into a fiber carrying the graphene flakes. | 2022-03-10 |

A weight average molecular weight Mw of a dissolved component obtained when the fiber for artificial hair is dissolved in hexafluoroisopropanol is 46,000 or more and less than 65,000. | 2022-03-10 |
| 20220074080 | SYNTHETIC POLYMERIC FIBERS ADDITIVATED WITH LIGNIN, THEIR PROCESS OF OBTAINING AND USE FOR MANUFACTURING TEXTILE PRODUCTS - Applied in the field of manufacturing textile products, the present invention provides compositions of synthetic polymeric fibers containing from 0.25% to 4.00% of lignin originated from the Kraft process, which are incorporated into the polymer through a subsequent extrusion process with the spinning process, by the use of a double-screw extruder coupled to a spinnerette. The obtained fibers are used in the production of textile products with anti-UV properties due to the presence of lignin, and with greater tenacity, resistance to bursting and antioxidant activity of the knit. | 2022-03-10 |
| 20220074081 | METHOD FOR PRODUCING CARBON NANOFIBER COMPOSITE AND CARBON NANOFIBER COMPOSITE - A method for a carbon nanofiber composite, which can obtain a carbon nanofiber composite with high productivity and high activity, and which does not require removal of fluidizing materials or dispersing materials, provides a carbon nanofiber composite having improved dispersibility. The method for producing the carbon nanofiber composite includes bringing at least one catalyst and at least one particulate carbon material into contact with at least one gas containing at least one gaseous carbon-containing compound while mechanically stirring the catalyst and the particulate carbon material in a reactor. The carbon nanofiber composite includes carbon nanofibers and at least one particulate carbon material, wherein the particulate carbon material has 70% by volume or more of particles with a particle diameter of 1 μm or less, and/or a median diameter D50 by volume of 1 μm or less. | 2022-03-10 |
