STUDY OF FIBER LENGTH DISTRIBUTION IN RELATION TO PHYSICAL PROPERTIES AND YARN QUALITY IN EGYPTIAN COTTON
IBRAHIM AHMED MAHMOUD ABD EL-AZIEZ;
Abstract
The present study was undertaken to investigate effects and reliability of fiber length distribution on some other variables and on yarn quality and yarn appearance.
Materials used in this study comprised seven commercial varieties. Three of these varieties, belong to the extra-long staple category, i.e. Giza 45, Giza 70 and Giza 88 and the other four ones belong to the long staple class, i.e. Giza 86, Giza 89, Giza
80 and Giza 83. Every variety was represented by three lint
cotton grades these were Fully Good (FG), Good (G) and Fully
Good Fair (FGF).
Studied fiber properties included the fiber length expressed by each of 2.5 % , 50 % span lengths, uniformity ratio and short fiber content. Fiber strength at (118" gauge) and elon_gation percent measured by Stelometer instroment, fiber stiffness and toughness were derived.
Micronarie value, Maturity percentage and hair weight were measured by Fineness & Maturity Tester (FMT). All of these properties were tested according to ASTM- Designations .
Cotton samples were spun into " 60s" carded yarn using a twist factor "3.6"; Yarn strength was determined by the
Statimate L.L Automatic Tensile Tester and yarn appearance
grades were converted into a numerical index.
