  • Patent number: 11976396
    Abstract: The present disclosure relates to a method for producing a nonwoven fabric that improves filtration performance when applied as a filter material. By adjusting the modification ratio of the Y-shaped cross-section of polyester filaments constituting the nonwoven fabric, when applied to a filter by increasing a specific surface area of the nonwoven fabric, it increases the collection amount of the materials to be filtered and maintains a low differential pressure, thus enabling long-term use.

  • Patent number: 11970674
    Abstract: The present disclosure relates to a method for preparing a non-woven fabric which improves impregnation and release properties of a fabric softener in the non-woven fabric in order to apply the non-woven fabric to a dryer sheet (sheet-type fabric softener). When increasing porosity and specific surface area in a non-woven fabric made of two-component blended polyester long fibers, impregnation and release rate of a fabric softener are improved even when the non-woven fabric is lightened, making it possible to apply the non-woven fabric to a dryer sheet.

  • Publication number: 20240091730
    Abstract: The present invention relates to the stabilization of an effective ingredient by using a mineral material. In the present invention, the effective ingredient can be stably supported using the mineral material, and a microcapsule obtained by the manufacturing method according to the present invention, when discharged to nature, causes no environmental problems due to encapsulation ingredients thereof being the same as soil ingredients, and thus can avoid micro-plastic issues.
