Patent number: 11976396Abstract: 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.Type: GrantFiled: June 11, 2019Date of Patent: May 7, 2024Assignee: KOLON INDUSTRIES, INC.Inventors: Woo-seok Choi, Min-ho Lee, Hee-jung Cho, Young-shin Park, Jung-soon Jang

Patent number: 11970674Abstract: 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.Type: GrantFiled: December 19, 2019Date of Patent: April 30, 2024Assignee: KOLON INDUSTRIES, INC.Inventors: Young-shin Park, Min-ho Lee, Jung-soon Jang, Hee-jung Cho, Woo-seok Choi
