Title:
COMPOSITE INSOLE AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/219161
Kind Code:
A1
Abstract:
A composite insole and manufacturing method thereof. The insole comprises a hydrophilic surface layer and a bottom layer. The hydrophilic surface layer is manufactured by PU foaming to create a hydrophilic foam body, then cutting the hydrophilic foam body into a plurality of thin sheets. A surface of the thin sheet can be press-laminated with a breathable fabric to form a semi-finished hydrophilic surface layer. The bottom layer of the insole is manufactured by PU or EVA foaming to create a foam body, then cutting the foam body into a plurality of thin pieces. A hole can be optionally punched, according to perforation designs, in the thin piece to form a semi-finished bottom layer. The semi-finished hydrophilic surface layer and the semi-finished bottom layer can then be pressed together to form a single sheet. A forming mold is used to perform insole forming, followed by trimming or edge finishing to form a composite insole. The composite insole has the properties of shock absorption, uniform pressure release, moisture absorption, and heat absorption. The composite insole provides, when in contact with human feet, a drying (moisture absorption) and cooling (heat absorption) effect, thereby improving comfort and usage effectiveness.
