Biodegradable fibers, processes for their production and their use, and fiber braids or filters containing them |
| abstract |
A method for producing biodegradable fibers, comprising the following steps: a) providing at least one alcoholic solution of at least one silane compound selected from the group consisting of tetraalkoxysilanes, trialkoxysilanes, halosilanes and mixtures thereof; b) providing an aqueous solution of at least one organic acid with a pKa value of <2.0 selected from the group consisting of sulfonic acids, sulfuric acid esters, phosphonic acids, phosphoric acid esters and mixtures thereof; c) Mixing the solutions provided in step a) and b) and mixing for 4 hours to 1 week at a temperature of 20 to 70 ° C; d) removing at least part of the alcohol from the mixture from step c) and then cooling the concentrated mixture to a temperature of 20 to -25 ° C; e) storing the cooled mixture from step d) until a viscosity of 10 to 75 Pa · s, measured at 4 ° C. using a rheometer with a coaxial cylinder measuring attachment and a shear rate of 10 s -1 , is reached; f) spinning the mixture from step e) into continuous fibers; wherein during steps c) to e) the silane compound is crosslinked and at least part of the organic acid is incorporated into the resulting network via covalent bonds and / or contributes to crosslinking. |
