  • High dielectric non-woven fabrics and their synthetic process
    Publication number: 20030209839
    Abstract: The present invention relates to high dielectric non-woven fabrics and their synthetic process. Particularly, the present invention relates to a process for preparing high dielectric non-woven fabrics comprising the steps of (a) mix-spinning polyvinylidene fluoride (PVDF) and polypropylene (PP) to prepare a fiber, (b) polarizing the fiber prepared in the step (a) to improve the dielectric constant of the fiber, and (c) manufacturing non-woven fabrics from the fiber having improved dielectric constant, prepared in the step (b), and non-woven fabrics prepared according to the mentioned process.
    Type: Application
