• Elongation

    Chapter 2 - Cotton value addition - The impact of cotton fibre properties on textile 

    Generally fibre elongation (extension at break) is measured at the same time as fibre strength, it being determined by genetic and environmental factors. An increase in elongation is associated with an increase in yarn and greige fabric elongation and nep formation, the relationship between yarn elongation and fibre elongation being a function of fibre length and yarn twist and linear density. Yarn elongation significantly affects weaving efficiency. An increase in fibre elongation can sometimes reduce spinning end-breakage and yarn strength. A level above 7% is desirable.
