Il-Sun Ryu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8353326
    Abstract: A three-dimensional fabric with three-layered structure is provided. The three-dimensional fabric comprises a surface layer, a backing layer, an intermediate layer, a first interconnection portion for connecting the surface layer and the backing layer, and a second interconnection portion for connecting the intermediate layer and the backing layer. The three-dimensional fabric with three-layered structure can be woven on a single loom in a batch operation and undergo transformation between two-dimensional shape and three-dimensional shape. This fabric is applicable as materials for blinds with high light-shielding rate because intermediate portions have a multi-layered structure.
    Type: Grant
    Filed: May 14, 2010
    Date of Patent: January 15, 2013
    Assignees: Woongjin Chemical Co., Ltd., Youil Corporation Co., Ltd.

  • Publication number: 20100218841
    Abstract: A three-dimensional multilayer fabric is provided. The fabric comprises a surface layer, a backing layer, and an intermediate layer connecting the surface layer and the backing layer. The intermediate layer has a multi-layered structure where a multiple of a fabric is separated each other. The three-dimensional multilayer fabric can be woven on a single loom in a batch operation and undergo transformation between two-dimensional shape and three-dimensional shape. This fabric is applicable as materials for blinds with high light-shielding rate because intermediate portions have a multi-layered structure.

  • Patent number: 7694696
    Abstract: A three-dimensional multilayer fabric is provided. The fabric comprises a surface layer, a backing layer, and an intermediate layer connecting the surface layer and the backing layer. The surface layer includes sequential unstitched surface portions and sequential stitched surface portions formed in an alternating and repeating pattern. The unstitched surface portions of the surface layer are essentially composed of surface warp threads only, and the stitched surface portions of the surface layer are composed of the surface warp threads and intermediate warp threads. The backing layer includes sequential unstitched backing portions and sequential stitched backing portions formed in an alternating and repeating pattern. The unstitched backing portions of the backing layer are essentially composed of backing warp threads only, and the stitched backing portions of the backing layer are composed of the backing warp threads and the intermediate warp threads.
