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 zwitterionic resin is manufactured by a manufacturing method which includes the following steps. A first thermal process is performed on a first crosslinking agent and a choline having hydroxyl group or amino group to form a first mixture, in which the first crosslinking agent includes an isocyanate group. A second thermal process is performed on the first mixture, a second crosslinking agent, a chain extender, and an amino acid to form the zwitterionic resin, in which the chain extender includes a polyol.

A stable aqueous dispersion containing a mixture of an anionic polymer, quaternary ammonium salt, a dispersion agent and water. The dispersing agent is poly (acrylamide-co-acrylic acid) or copolymer of maleic acid and an olefin. The dispersion can be applied to textile materials and nonwoven substrates. Nonwoven substrates, such as polypropylene substrates can be treated with the dispersion to provide a highly active quick killing antimicrobial effect: Log 4 reduction in 5 minutes. This would be useful to deactivate the SARS-CoV-2 virus, which causes Covid-19.
