The present invention relates to a composition, textile, and mask for reducing the inhalation of pollutants. The composition includes an aqueous solution of an inorganic iodide compound, a metal phthalocyanine, and a polymeric binder. The inorganic iodide can be cuprous iodide, the metal phthalocyanine can be iron phthalocyanine, and the polymeric binder can be polyvinylpyrrolidone or polyvinyl alcohol. This pollutant-inactivating composition neutralizes pollutants such as nitrogen dioxide, sulfur dioxide, ozone, volatile organic compounds and other unpleasant airborne agents, without requiring elevated temperatures or bulky canisters containing adsorbents. Optionally, a humectant can also be incorporated into the coating solution to retain moisture in the active filter matrix, which enhances the activity of the composition to inactivate oxidizing gases and other toxic constituents of air pollution.

A liquid-crystal polyether fiber with high tensile strength has an ash content of 0.3 percent by weight or less, a degree of fusion (f) of 3 or less, and a tensile strength of 18 cN/dtex or more. The liquid-crystal polyether fiber has few residues of an anti-fusion agent and causes no fusion between filaments.

A description is given of continuous fibers based on cellulose and/or cellulose derivatives, more particularly for producing flame-retardant textiles or carbon fibers. The cellulose and/or the cellulose derivatives are in a dehydrated form in the continuous fibers. The oxygen content is 29 to 39 wt %, the limiting oxygen index LOI is 25 to 40 (according to DIN EN ISO 6941; 2004-05) and the density is 1.3 to 1.45 g/cm.sup.3 (according to DIN 65569-1; 1992-10). The continuous fibers may be produced advantageously by impregnating the starting fibers with a solution, more particularly an aqueous solution, of a specific salt which under thermal conditions releases a dehydrating acid which brings about the dehydration of cellulose and/or of cellulose derivatives in a subsequent thermal stage. The continuous fibers of the invention can be used in particular to produce advantageous carbon fibers.

A method for pretreatment of cellulose-containing textiles characterized by applying an aqueous solution with a pH between 1 and 7 and containing at least one agent for durably changing the surface morphology of the cellulose, preferably a neutral salt.

A new technique for treating non-PAN-based pre-cursor polymeric fibers, tows, yarns, and films has been created for use in making stabilized pre-cursor polymers. By applying stepwise or non-stepwise microwave and/or ultraviolet radiation to the pre-cursor polymeric fibers, tows, yarn, or films prior to the stabilization thereof, a reduction in time for the costly stabilization process is achieved. Application of this technique extends to less-costly production of carbon fibers, for uses in industries such as automotive, aviation, trains, medical, military, sporting goods, orthopedics, and other industries. The pre-cursor polymeric fibers, tows, yarns, or films may be a multi-component polymer composite comprised of a non-PAN-based polymeric fiber, tow, yarn, or film and at least one or more constituent materials. Carbonization of such pre-cursor polymeric fibers, tows, yarns, or films results in less-costly carbon fibers that perform equally, if not better, than traditional costly PAN-based carbon fibers.
