Natural Fibre
Medium-staple cotton fibre derived from the Gossypium hirsutum plant is the most widely cultivated textile fibre in the world. In the global yarn trade, upland cotton represents the standard material for producing denim, t-shirts, and bed sheets. This fibre is classified by its staple length, color grade, and micronaire.
Yarn Spinning
Purchasing offices select this fibre type for its versatility and lower cost compared to extra-long staple cotton. When buying upland cotton, the mill relies on high volume instrument testing to verify that the fibre length and strength meet the requirements of the spinning system. This prevents processing issues like yarn hairiness or low tensile strength.
Fibre Evaluation
Harvesting machines collect the cotton bolls from the field before they are sent to the ginning mill. Ginning separates the lint from the seeds and removes large pieces of leaf, stem, and trash. The cleaned lint is then compressed into bales, sampled, and tested for quality.
The average staple length of this variety ranges from twenty-five to thirty-two millimeters. Spinners adjust their combing and carding settings to match this length range, ensuring that the yarn produced is smooth and uniform.
Market Standard
Standard commercial contracts use these measurements to determine the final price of the cotton delivery. It ensures that the mill receives the correct grade of fibre for its target yarn count. This variety remains the workhorse of the global apparel industry.
