Research papers
AWTA has achieved a world wide reputation for its research work and now has one of the largest teams of scientists working on raw wool metrology.
Our scientists regularly report on their work to the technical forums of the International Wool Textile Organisation (IWTO). Papers published by the Company's scientists are available for reference purposes and academic use.
Access to research publications produced by other organisations, when approval is provided, is also available.
Papers are grouped in the following categories, with pdf documents available for download and viewing.
