Title: Hermann Schwab: Innovator in Textile Printing Technologies
Introduction
Hermann Schwab is a notable inventor based in Ludwigshafen, Germany. He has made significant contributions to the field of textile printing, particularly in the development of innovative resist printing processes. With a total of 3 patents, Schwab's work has had a lasting impact on the textile industry.
Latest Patents
One of Schwab's latest patents is focused on a resist printing process. This process is designed for the production of resist prints under reactive dyes on textile materials that consist of cellulose fibers or blends of cellulose fibers with other fibers. The method utilizes reaction products of bisulfite adducts of aldehydes or ketones with ammonia, primary amines, or secondary amines in specific molar ratios. The preferred reaction product involves a bisulfite adduct of acetaldehyde and ammonia, which results in high stability of the resist print pastes, leading to high color yields and satisfactory resist effects.
Another significant patent involves transfer printing of cellulosic fabrics. This process entails impregnating the fabric with aqueous solutions of compounds that serve as solvents for transfer dyes and potential crosslinking agents for cellulose. The fabric is then dried and printed using a transfer process in the presence of a cross-linking catalyst, which enhances the effectiveness of sublimable dyes or optical brighteners.
