This report is a summary of a partnership project, involving Australian as well as overseas co-operators, which was conducted to evaluate four Australian cotton varieties in terms of their utility value to the textile mill and their agronomic and thus economic viability on the cotton production side. The four varieties, Sicala 40, Siokra V16, Sicala V2i, and Sicot 189, were grown and ginned by Auscott Ltd. , Narrabri, within the frame work of a Cotton Seed Distributors Ltd (CSD) variety trial. These varieties are representative of the bulk of Australian raw cotton production. As a result of a cooperative approach pursued by Cotton Research and Development Corporation (CRDC), two renowned German manufacturers of mill preparatory equipment and open-end spinning frames, ie Trutzschler GinbH and Schlafhorst Autocoro GinbH, respectively, joined the consortium and conducted processing studies on a laboratory scale with sample bales that were shipped to Europe.
