    Ceramide-containing sheath/core composite fibers were prepared by a meltspinning process, for improving skincare clothing and mitigating atopic dermatitis. We built a database for selecting the base polymer containing the ceramide, encapsulating it, and optimizing the parameters of the unit manufacture of a master-batch chip, to apply the subsequent process. We also evaluated how single-filament, spinning-composite-filament, and draw-textured-yarn manufacturing conditions affect the physical properties of the yarn. Furthermore, the effects of an eccentric sheath/core– and sheath/core-type structure on the sustained release of the ceramide were investigated. As a result, the possibility of the production of ceramide-containing sustained-release polypropylene yarns was verified by HPLC analysis.
