It is a standard measure of cotton fibre length that is recognised globally. It can be measured in inches or millimetres. Span lengths over 2.5% are categorised as follows:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Classification of a span length of 2.5%<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Fineness fibre<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Weight per unit of fibre length determines fibre fineness. Weight and fibre fineness per unit length are inversely proportional to one another. The basis for categorising the fineness of a fibre is its micronaire (Microgrammes\/inch) grading.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1000\" height=\"391\" src=\"https:\/\/allawasaya.com\/textile\/wp-content\/uploads\/2023\/02\/image-1.png\" alt=\"\" class=\"wp-image-95\" srcset=\"https:\/\/allawasaya.com\/Tech-Gadgets\/wp-content\/uploads\/2023\/02\/image-1.png 1000w, https:\/\/allawasaya.com\/Tech-Gadgets\/wp-content\/uploads\/2023\/02\/image-1-300x117.png 300w, https:\/\/allawasaya.com\/Tech-Gadgets\/wp-content\/uploads\/2023\/02\/image-1-768x300.png 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Fibre tenacity<\/strong><br><br><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1000\" height=\"350\" src=\"https:\/\/allawasaya.com\/textile\/wp-content\/uploads\/2023\/02\/image-2.png\" alt=\"\" class=\"wp-image-96\" srcset=\"https:\/\/allawasaya.com\/Tech-Gadgets\/wp-content\/uploads\/2023\/02\/image-2.png 1000w, https:\/\/allawasaya.com\/Tech-Gadgets\/wp-content\/uploads\/2023\/02\/image-2-300x105.png 300w, https:\/\/allawasaya.com\/Tech-Gadgets\/wp-content\/uploads\/2023\/02\/image-2-768x269.png 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Fibre maturity-coefficient<\/strong><br>The maturity of the fibre is influenced by cotton development.
