Title: Jorg Hausdorf: Innovator in Sponge Cloth Technology
Introduction
Jorg Hausdorf is a notable inventor based in Furth, Germany. He has made significant contributions to the field of materials science, particularly in the development of sponge cloths and sponges made from decrystallized cellulose. With a total of 8 patents to his name, Hausdorf's work has advanced the understanding and production of eco-friendly materials.
Latest Patents
Among his latest patents is a process for producing a sponge cloth. This innovative sponge cloth is made from decrystallized cellulose modified by the acetyl group content, with an average degree of substitution ranging from 0.2 to 1.5. Notably, the cloth is free from any organic or inorganic sulfur compounds. The production process involves treating wood pulp with sodium hydroxide solution, followed by acetylation, drying, and dissolving in an organic solvent. The mixture is then combined with a pore-forming salt, fibers, and optionally pigment dyes and foaming agents. After spreading the mixture on a web, it is boiled in water and subsequently dried to create the finished cloth.
Another significant patent by Hausdorf is for a process to produce a sponge. Similar to the sponge cloth, this sponge is also made from decrystallized cellulose modified by an acetyl group content, maintaining the same average degree of substitution. The sponge is produced through a series of steps that include treating pulp with sodium hydroxide, acetylation, and pressing the mixture into a perforated mold. The mold is then placed in boiling water, allowing the sponge to form and be removed.
