The structure of siloxane in spinning finishes PU was analyzed. And the molecular weight of two siloxane samples was determinated by 29 Si\|NMR and viscometry and compared as well.
The paper addresses the development of spin-finishes of synthetic fibers. The ap plication of silicone in carbon fiber and high-speed spinning finishes is briefl y introduced.
Analysis methods for chemical fiber finish are introduced systematically, including chemical analysis, instrumental analysis and knowledge of using all these methods to analyze the compoment and the chemical structure of unknown finish.
