| 摘要 |
A simulated leather sheet material comprises: a polymer impregnated fibrous mass with a grain layer forming one surface, the grain layer having an actual density equal to its bulk density and a split layer forming the opposing surface, the split layer having a bulk density less than its actual density, said sheet material having a density decreasing from the grain layer to the split layer, the ratio of fibre to polymer being substantially uniform throughout said sheet material. There is also disclosed a method of forming such simulated leather sheet material. |
