Claims20
A method for making a composite article, comprising the steps of:
- a) mixing a lipophilic-rich cellulosic material (LCM) with a binder to provide a binder rich LCM, wherein the LCM comprises at least 2 wt % of a lipophilic component;
- b) drying the binder rich LCM to provide a dried LCM;
- c) mixing the dried LCM with a tackifier to provide a composite mixture;
- d) forming a cellulosic mat from the composite mixture;
- and
- e) consolidating the cellulosic mat to form the composite article.
