Abstract
Methods of making an artificial leather substrate from leather waste (e.g., shavings, such as wet blue, and/or pulverized trim scrap) and products formed using the artificial leather substrate are disclosed. In one example, the artificial leather substrate comprises a composite web comprising leather waste mixed with a lightweight web, a lightweight web atop the composite web, and another lightweight web atop the first lightweight web. A method of making the artificial leather substrate includes the steps of mixing one or more fiber components, leather shavings, and/or pulverized leather trim scrap to form the composite web; needle punching the composite web; and bonding the composite web.
