Title: Paul Schafflutzel: Innovator in Fiber Material Printing
Introduction
Paul Schafflutzel is a notable inventor based in Basel, Switzerland. He has made significant contributions to the field of fiber material printing, holding a total of 3 patents. His innovative approaches have advanced the techniques used in dyeing and printing processes.
Latest Patents
One of Schafflutzel's latest patents is a process for printing fiber material by the direct printing process. This process involves using a print paste that includes at least one dye, a cellulose derivative or alginate as a thickener, and other customary assistants. The print paste contains ≤5% by weight of a homopolymer or copolymer based on acrylamide. This novel process allows for the creation of strong patterned prints on a white ground, characterized by good levelness, fastness properties, and sharp contours. The print pastes are noted for their good homogeneity, storage stability, and ease of handling.
Another significant patent is a process for dyeing or printing cellulosic fiber materials with reactive dyes. This method includes dyeing or printing the material with at least one reactive dye containing a chlorotriazinyl radical. The dyeing or print is then washed off with an aqueous solution that has at least 0.01 gram per liter of an alkaline earth metal salt added. This process results in dyeings and prints that exhibit good fastness properties.
