Cellulase dissolution technique for the study of chemically modified and crosslinked cotton



Cellulase enzyme of Penicillium funiculosum has been used for microsolubility test and compared with cuene dissolution technique by carrying out electron-microscopic observations on the acetylated and DMDHEU-crosslinked cottons. Cellulase being highly specific toward native cellulose, it acts only on unacetylated or uncrosslinked portions of the cotton leaving the rest of the cross section undisturbed. In this regard, cellulase dissolution technique has an advantage over the cuene dissolution technique currently used to evaluate modified and crosslinked cottons.
