“…These wool yields are comparable with the wool yields reported previously. For instance, Harizi et al [21] reported wool yields ranging from 50-70% for a Tunisian sheep breed, likewise, Ansari-Renani et al [22] also reported 69.3 ± 0.7% at most for the Iranian sheep breeds. Larger wool yields gain the attention of worldwide wool textile industries, and thus help a country to boost its economy.…”

The aim of this paper is to study wool fiber resources from Kenya that have been obtained from different breeds in order to characterize the basic properties of their wool to help improve the economic value of Kenyan wool. The Kenyan sheep industry has received less attention in terms of research and development when compared with large livestock. Wool quality and yield are essential to obtaining good returns in the international market. This study was conducted to analyze the wool yields and qualitative index of Kenyan sheep. The wool samples were taken from 95 crossbreed Dorper sheep comprising 23 males and 72 females between the ages of one and five years. Wool samples from the shoulders, flanks, back belly and legs were taken for analysis. The mean fleece weight was 2.04 ± 0.06 kg, with coefficient of variation of 37% for all the selected sheep; the average for the males was 2.06 ± 0.06 kg and the average for females was 2.02 ± 0.08 kg. The variation in the fleece weight was in the range of 0.7–3.3 kg. The yield percentages and impurities were analyzed and reported. The wide variations in fleece weight, the increase in sheep population and the trend of raw wool export suggests that there is potential for improving economic traits. Kenya can obtain trade benefits related to the wool industry by becoming a member of International Wool Trade Organization and by following economically sustainable practical approaches. It is essential to have good international and regional cooperation with countries that can share knowledge and training as well as marketing and information.

“…Carpet wool quality and its value are primarily determined by fiber diameter and length which reflect fineness and the degree of wool growth respectively. 8 Similarly, research results indicated that the wool fibers exposure to UV irradiation resulted in better shrinkage and dye ability. Enzyme treated fibers resulted in better dye rate and improved resistance to shrinkage (Wang et al 2020).…”

The wool fibers fineness and strength have a remarkable role to determine the quality of yarn and the subsequent fabrics. The fineness property of the wool fibers is a crucially important fiber property for grading, classifying, selecting for particular applications such as for suit, blanket, shirt, carpet, and so on. The fineness and strength properties of four indigenous (Menz, Wollo, Farta, Tikur), three exotic (Awasi, Dorper, Corrediale), and four cross-breed (50% Dorper, 50% Awasi, 75% Awsi, Washera/Awasi) sheep wool fibers from the four main body parts (sides, neck, back, and belly) at six teeth removed age of 11 different sheep breeds have been investigated. The samples of wool fibers have been conditioned for 24 h at 20ºC ± 1ºC temperature and 65% ± 2% relative humidity. The specimen for sampling has been determined based on ASTM D2130-01. The results revealed that the fineness and strength of whole fibers taken from different parts of sample sheep varied significantly within the breed and among the breeds. The result revealed that the strength and fineness of the wool fibers have a positive correlation and Ethiopian sheep wool fiber is suitable for numerous types of classical and technical applications.

“…The most important determinants of animal fibre quality are the species that produce it and the diameter of the fibre, as previously described for Iranian cashmere (AnsariRenani et al 2011a, b;Ansari-Renani 2012). The fleece of cashmere goats are double coated and consist of two major fibre types: coarse, medullated guard hair and fine, nonmedullated insulative down fibre (Allain 1992;Mitchell et al 1991;Nixon et al 1991;Ryder 1966;Carter and Clark 1943;Petrie 1995).…”

Iran together with Afghanistan is the third largest producer and exporter of cashmere in the world, after China and Mongolia. Nomads have a big share in producing Iranian cashmere. This study reviews the status of cashmere production, harvesting, marketing and processing by nomads of Iran in order to evaluate sustainability and to identify some constraints limiting productivity. The quality of Iranian cashmere, being long and highly curved, ranks third after China and Mongolia. The principal centres for the gathering and rough sorting of raw cashmere produced by nomads are Baft, Sirjan, Mashad and Birjand, with Mashad continuing as the centre of the Iranian cashmere industry. Nearly all the cashmere produced is bought directly from the nomads by middlemen and is dehaired and exported to Europe and China without major value addition.
