Ben Ameur2 1Textile Engineering Laboratory, University of Monastir, Monastir, Tunisia 2Technical Center of Creation, Innovation, and Supervision in Carpet and Weaving, Tunis, Tunisia Abstract This experiment was aimed to identify wool quality of Tunisian sheep breeds. Fiber characteristics of different ages and various sheep breeds were studied. A total of 84 sheep were used in this study. Results show that the factor 'breed' had a highly significant effect on all controlled parameters accept scoured yield and fibre length. Breed was the most important factor. By conducting well-planned sorting, “Fine Queue of west” sheep breed can supply the wool needed for textile industries. The wool of other sheep breeds can be used in handmade carpets.

  • Genetic Variability Studies in Gossypium Barbadense L
    Electronic Journal of Plant Breeding, 1(4): 961-965 (July 2010) Research Article Genetic variability studies in Gossypium barbadense L. genotypes for seed cotton yield and its yield components K. P. M. Dhamayanathi , S. Manickam and K. Rathinavel Abstract A study was carried out during kharif 2006-07 with twenty five Gossypium barbadense L genotypes to obtain information on genetic variability, heritability and genetic advance for seed cotton yield and its yield attributes. Significant differences were observed for characters among genotypes. High genetic differences were recorded for nodes/plant, sympodia, bolls as well as fruiting points per plant, seed cotton yield, lint index indicating ample scope for genetic improvement of these characters through selection. Results also revealed high heritability coupled with high genetic advance for yield and most of the yield components as well as fibre quality traits. Sympodia/plant, fruiting point /plant, number of nodes/plant, number of bolls per plant, and lint index were positively correlated with seed cotton yield per plant and appeared to be interrelated with each other. It is suggested that these characters could be considered as selection criteria in improving the seed cotton yield of G. barbadense , L genotypes. Key words : Gossypium barbadense , genetic variability, heritability, genetic advance, lint index, selection criteria Introduction Seed cotton yield is a complex trait governed by Cotton is the most widely used vegetable fibre and several yield contributing characters such as plant also the most important raw material for the textile height, number of monopodia, number of industry, grown in tropical and subtropical regions sympodia, number of bolls, number of fruiting in more than 80 countries all over the world.

  • Long Staple Processing and Textile Testing
    Volume 3, Issue 3, Fall 2003 Long Staple Processing and Textile Testing Dean R. Cobb Institute of Textile Technology ABSTRACT Several vendors in the long staple processing area and the textile testing unveiled some improvements to their existing offerings. The long staple improvements came in the form of better design, more productivity, more electronic controls, less maintenance requirements, versatility, and cross compatibility with automation of all types. Improvements from some testing vendors mainly concentrated on yielding more information from the same tests; like the sticky cotton measurement from Lintronics and Weavability from Uster. Keywords: Long staple processing, short staple textile testing, Introduction • Modular frame assemblies with no cross-rails.
