Document Type and Number:
WIPO Patent Application WO/2011/027920
Kind Code:
A1
Abstract:
The object of the present invention is to provide a production method for a polyurethane sheet using N/P conjugate fibres, wherein the N/P conjugate fibres can be used as a fabric such that scratches can be prevented from occurring in the surfaces of electronic products when the PU sheet is used as a protective casing for electronic products, and wherein an advantage of PU sheets produced by the wet processing method (the advantage that the surfaces of casings do not become smooth and can have a certain frictive force) can be retained so as to prevent electronic products from falling to the floor and becoming damaged.
