Relationship of Cotton Fiber Properties to Yarn Tenacity

Fiber tenacity, elongation, length, fineness, and color were measured for 5 Gossypium barbadense L. and 37 G. hirsutum L. fiber samples. These samples were spun into 12- and 27-tex yarns on a ring system and into 27-tex yarns on an open-end system; yarn tenacity was determined. Fiber tenacity and length were positively correlated with yarn tenacity. No correlations of fiber fineness with tenacity of 27-tex yarns were detected. A substantial portion of the variation in 27-tex yarn tenacity was attributable to variations in fiber tenacity and length.
