請問二層皮的英文是什麼?

二層的英文是 split leather

I've found one of the article and now post it to you for reference :)

English
-----------
Main Business: ..... We select best grain and split leather to produce leather work glove with best quality.

Chinese
------------
主要業務: .....我們選用上等的頭層皮和二層皮來生產出高質量的勞保手套。

我同D客是講叫做split leather
