Title:
DEVICE AND METHOD FOR SEPARATING MIXED FIBERS USING TRIBOELECTRIC EFFECT
Document Type and Number:
WIPO Patent Application WO/2022/156775
Kind Code:
A1
Abstract:
The present invention discloses a device and method for separating mixed fibers using a triboelectric effect, which may separate protein-based fibers and/or cellulose-based fibers without water and chemicals. The mixed fibers include the protein-based fibers, the cellulose-based fibers and/or synthetic fibers, and the device includes: a fiber extraction device configured to extract single fibers from the mixed fibers; a triboelectric device configured to charge the single fibers into charged fibers using the triboelectric effect; a fiber separation device configured as one or more separation chambers to separate the charged fibers according to polarities thereof; a fiber collection device configured to collect the separated fibers; and an air flow generation device configured to generate and maintain an air flow flowing steadily to carry the single fibers from the fiber extraction device through the triboelectric device and the fiber separation device to the fiber collection device.
