CELLULASE PREPARATION AND METHOD OF TREATING CELLULOSIC FIBER THEREWITH.

摘要

A cellulose preparation which can improve the color and hand of cellulosic fibers while suppressing a lowering in the strengths of the fibers. The cellulose of the preparation can adsorb crystalline cellulose and has an avicellase activity to CMCase activity ratio of 0.1 or above. The fibers treated with this preparation can retain a relative residual tensile strength of at least 75 % per count at a weight reduction rate of 5 %.
