Wool Science

Research into wool and its properties is one of IWTO’s most important activities. IWTO’s wool research is guided by specialized Technical Advisory Groups, under the leadership of our different working groups.

Here, we offer a reference of the latest wool research by topic. We aim to provide peer-reviewed research in leading journals that is available on an open-source basis.
