Abstract: A PROCESS IS PROVIDED FOR PRODUCING A HEAT-STABILIZED CHAR OR SUBSTRATE FROM ACRYLIC FIBERS WHICH CAN BE CONVERTED INTO HIGH QUALITY CARBON OR GRAPHITE FIBERS. THE FIBERS ARE FIRST TREATED IN A POLYOL SOLUTION CONTAINING A BASIC NITRILE POLYMERIZATION CATALYST FOLLOWED BY AN AIROXIDATION AT TEMPERATURES OF 270*C. AND ABOVE. THE PREOXIDATION TREATMENT DRASTICALLY REDUCES THE TIME NORMALLY REQUIRED FOR EFFECTING THE NECESSARY OXIDATION. THE CARBONIZABLE OR GRAPHITIZABLE SUBSTRATED OBTAINED YIELD CARBON AND GRAPHITE FIBERS OF IMPROVED PROPERTIES.

Abstract: AN IMPROVED PROCESS FOR THE THERMAL STABILIZATION OF AN ACRYLIC FIBROUS MATERIAL OR FILM IS PROVIDED. THE FIBROUS PRECURSOR OR FILM IS IMPREGNATED WITH A STABILIZATION PROMOTING AGENT BY CONTACT WITH A SOLUTION OF THE SAME PROVIDED AT A MODERATE TEMPERATURE, DRIED TO REMOVE THE SOLVENT, AND HEATED IN AN OXYGEN-CONTAINING ATMOSPHERE AT A MORE HIGHLY ELEVATED TEMPERATURE UNITL A STABILIZED FIBROUS MATERIAL OR FILM IS FORMED. THE STABILIZATION PROMOTING AGENTS EMPLOYED IN THE PRESENT PROCESS ARE MINERAL ACIDS, SULFONIC ACIDS, AND CERTAIN CARBOXYLIC ACIDS. THE RESULTING STABILIZED FIBROUS MATERIAL OR FILM IS NON-BURNING, AND MAY BE UTILIZED AS A FIRE RESISTANT FIBER, RABRIC, OR FILM, OR OPTIONALLY CARBONIZED OR CARBONIZED AND GRAPHITIZED TO FORM A CARBONACEOUS FIBROUS MATERIAL OR FILM.

Abstract: A process is provided wherein the thermal stabilization of an acrylic fibrous material is accelerated by heating in an oxygencontaining atmosphere in the presence of a catalytic quantity of Co(II) and Ce(III) metallic cations which have been found capable of promoting the oxidative cross-linking of adjoining polymer molecules. The resulting stabilized fibrous materials are nonburning when subjected to an ordinary match flame, and may be utilized as fire resistant textile fibers, or optionally converted to a carbonized fibrous material by heating in an inert atmosphere at a more highly elevated temperature.

Abstract: THIS INVENTION PROVIDES A PROCESS FOR PREOXIDIZING ACRYLIC FIBERS WHICH CAN BE CONVERTED INTO CARBON OR GRAPHITE FIBERS OF HIGH STRENGTH AND MODULUS. THE PROCESS INVOLVES FIRST HEATING THE FIBER, WHILE UNDER TENSION, TO A TEMPERATURE BELOW 250*C. IN AN ATMOSPHERE OF OXYGEN AND BROMINE FOR A TIME SUFFICIENT TO FORM A PERMEABLE SHEATH AROUND THE FIBER. THE FIBER IS NEXT HEATED IN AN OXYGEN ATMOSPHERE AT A TEMPERATURE ABOVE 250*C. FOR A TIME SUFFICIENT TO ALLOW COMPLETE PERMEATION OF OXYGEN THROUGHOUT THE CORE OF THE FIBER. THE OXIDIZED FIBERS ARE USEFUL FOR THE CONSTRUCTION OF FIREPROOF FABRICS AND MAY ALSO BE CARBONIZED OR GRAPHITIZED BY HEATING IN AN INERT ATMOSPHERE AT THE APPROPRIATE TEMPERATURES.

Abstract: There is provided a process for chemically pretreating reclaimed cellulose fibres to be used in the production of moulded bodies from regenerated cellulose, wherein the pretreatment includes one stage, in which stage acid metal removal and acid oxidative bleaching are carried out together. Advantages include that the propensity of the regenerated cellulose to clog when flowing in a tube and through a nozzle is reduced. This is believed to be an effect of an efficient metal removal. The need for additional bleaching steps and/or metal removing steps is reduced or even eliminated. A one-stage method is more efficient, faster and less costly compared to a multi-stage method according to the prior art. From an environmental perspective, acidic metal removal is preferred over removal by chelating agents such as EDTA.
