Sponge and process for making the same |
| abstract |
A sponge of decrystallized cellulose modified by an acetyl group content, where the average degree of substitution is 0.2 to 1.5. No organic or inorganic sulfur compounds are present in the sponge. The sponge is produced by treating pulp with sodium hydroxide solution, then treating it with acetylating substances, drying and dissolving in an organic solvent with the addition of a pore-forming salt, fibers and optionally pigment dyes, pressing the mixture into a perforated mold whose receiving volume corresponds to the dimensions of the sponge to be produced, then placing the mold with its contents in boiling water, and removing the sponge thus formed in the mold. |
