    摘要: Carboxylated, mercerized cellulose fiber having at least 12 meq/100 g of carboxyl substitution at the C-6 position of the anhydroglucose units, which includes at least 20% cellulose II, may be produced by catalytically carboxylating mercerized cellulose fiber in at least two catalytic carboxylation stages in a continuous series in which the pH is adjusted, and a primary oxoammonium salt catalyst (or precursor thereof) and secondary oxidant is added, at the beginning of each stage. Optionally, the carboxylated, mercerized cellulose may be made substantially free of aldehyde groups by means of a stabilizing step following the final carboxylation stage, in which aldehyde groups present in the fibers are converted to carboxyl groups.

    摘要: The present invention relates to a method of obtaining a solid material based on a polymer having its cellobiose units exhibiting the following characteristics: at least some of the cellobiose units have at least one carboxylic acid function attached to the C6 carbon, the other C6 carbons having a primary alcohol function attached thereto; and at least some of the cellobiose units have at least one of the two rings open between the C2 and C3 carbons, the other C2 and C3 carbons forming a ring and having an alcohol function attached thereto. Such a material, advantageously a textile, may be used as a compress.
