A solid particulate reactive sorbent for decontaminating toxic chemical and biological agents and its method of making. The reactive sorbent comprising a plurality of aggregates formed from linked hydrophilic nanoparticles and individual nanoparticles that bind at least one detoxifier, such that the sorbent absorbs the agents, allowing the detoxifier to oxidize and decontaminate the agents for removal. More preferably, the hydrophilic nanoparticles comprise fumed silica and the detoxifier comprises hydrogen peroxide.

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.

An arc resistant acrylic fiber includes an acrylic polymer. The arc resistant acrylic fiber also includes an infrared absorber in an amount of 1 wt % to 30 wt % with respect to a total weight of the acrylic polymer.

The invention aims to provide a method of manufacturing a carbon fiber resin tape capable of being adhered with a high adhesive strength without being pressurized at high pressure nor heated at high temperature. A method of manufacturing a carbon fiber resin tape F2 comprises: a first step of immersing a carbon fiber bundle F1 having several carbon fibers in reduced water having a negative oxidation-reduction potential to flatten the carbon fiber bundle; a second step of immersing the above-described carbon fiber bundle in an adhesive solution containing an adhesive S, alumina sol A, and potassium persulfate B after the above-described first step; and a third step of drying the above-described carbon fiber bundle after the above-described second step.
