Title:
BIODEGRADABLE AND HYDROLYZABLE SHEET
Document Type and Number:
WIPO Patent Application WO/1997/013920
Kind Code:
A1
Abstract:
A biodegradable and hydrolyzable sheet which comprises at least one biodegradable synthetic fiber, at least one natural fiber and/or regenerated fiber, the fibers being bonded to one another with a binder which substantially loses its adhesive power in water. This sheet has a combination of a given tensile strength, a good softness, and a desired liquid absorption capability and, in addition, a desired biodegradability. Therefore, the sheet, when flushed away in a flush toilet, does not cause any significant increase in solid residues in a septic tank and sewage treatment equipment, rendering the sheet suitable particularly for wet wipes.
