Title: Alfred Steiger: Innovator in Textile Fabric Treatments
Introduction
Alfred Steiger is a notable inventor based in Wattwil, Switzerland. He has made significant contributions to the field of textile fabric treatments, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents is a process for producing cloque or undulating effects on the surfaces of textile fabrics made from synthetics. This process involves a first heat-treatment at temperatures ranging from 100°C to 200°C, applying tension or pressure to temporarily increase the density of the threads in the fabric. Following this, the fabric is printed with a heat-resistant resist according to a specified pattern and subjected to a second heat-treatment at similar temperatures, preferably without tension, for a duration of 30 seconds to 10 minutes. This step decreases the density of the threads in areas not printed with the resist paste, which is then removed by washing, and the fabric is dried using conventional means.
Another significant patent involves a process for dry dyeing and printing of flat textile fabrics containing cellulose fibers. This method includes a cross-linking treatment of the fibers, where the fabric is treated with an aqueous solution of cross-linking agents. After pre-drying, the fabric is dyed or printed in dry condition with sublimable dyestuffs and heated in the presence of an acid or potentially acid catalyst.
