Document Type and Number:
WIPO Patent Application WO/2010/140853
Kind Code:
A2
Abstract:
The present invention relates to artificial leather comprising a microfibre nonwoven fabric impregnated with an elastomer, in which the residual set at 30% extension is no more than 10% in the longitudinal direction and is no more than 20% in the transverse direction. By optimising the residual set of the artificial leather, and specifically by optimising the residual set at 30% extension to be no more than 10% in the longitudinal direction and no more than 20% in the transverse direction, the present invention allows artificial leather which has expanded during formation to contract and recover easily, and prevents wrinkles from occurring even when used in products having many curves.
