Abstract

<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">The bundle tenacity and crystallite orientation of cotton fibres of 25 varieties of <i>Gossypium barbadense</i> species grown at Coimbatore farm of the Central Institute for Cotton Research in 1983 crop year were determined. The crystallite orientation was expressed in term of 40, 50 and 75% X-ray angles and the Hermans orientation factor, and the average orientation angle α_m was computed from the latter. The bundle tenacity and the orientation parameters were correlated. A conclusion of the study is that the varieties should be characterized for strength on the basis of the Hermans factor and not the X-ray angles conventionally used.</span>
