Nep Content in Relation to Cotton Fiber Quality Characteristics
Mar 27, 2019


Textile Technology Research Centre conducted a two-year research programme to determine the nep content in baled cotton and the actual processes that contribute to their evolution and increase. Cotton samples were collected from every ginning industry participating before the gin stand, before the lint cleaners and from the final ginned product for testing for their nep and trash content with the Zellweger Uster AFIS instrument and for their fiber quality characteristics with an HVI . Measurements revealed that a considerable nep content in seed cotton is increased during the ginning process and the following cleaning stages. Quality measurements revealed that the higher the nep content in the final product, the lower the uniformity ratio and the higher the short fiber content.
