摘要:
In the production of elasthane threads by solution spinning of polyurea polyurethanes by conventional spinning processes, excellent stabilization against light and noxious gases are obtained if at least one component of the system to be spun contains tertiary amino groups and the substances used as antioxidizing agents are phenols of the kind which do not form colored nitro compounds.
