Latest Patents

Dross's latest patents include a groundbreaking process for the continuous production of acrylonitrile filaments and fibers. This innovative method allows for the production of crimped filaments and fibers from acrylonitrile polymers and copolymers containing at least 40% by weight acrylonitrile units. The process utilizes dry spinning from highly polar solvents, where filaments are brought to extremely low solvent contents in the spinning tube using superheated steam. This technique ensures that spun PAN filaments of good natural color are obtained without the need for washing or drying stages. Additionally, Dross has developed a process for wetting thread bundles with liquids, which involves a device that releases liquid through slotted nozzles, enhancing the efficiency of the production process.
