Fiber characteristics of the dromedary camel in the Arabian Peninsula

Dromedary camel fibers have long been utilized to make clothes, tents, ropes, mats, and carpets, however, only a minority of these fibers are currently used to produce textiles. Dromedary fiber classification based on quality traits is essential to investigate its textile potential. Therefore, the objectives of this study were to (1) develop a classification protocol for dromedary camel fibers based on crimp (i.e., shape), (2) investigate the characteristics of each fiber class using length, diameter, and medulla (i.e., the innermost hair layer) and (3) determine which fiber class is most suitable for the textile industry. Fiber samples were obtained from the mid-torso of 32 Arabian Peninsula camels of different types. Five crimp categories were identified (straight, C-shaped, wavy, ringed, and kinky). Across all crimp categories, the average length ranged from 20.20 – 43.93 mm whereas the mean fiber diameter ranged from 29.74 – 72.11 μm. Percent medullation extended from 68% to 100% with noticeable variation between crimp categories. Overall, fiber traits significantly differed between the crimp categories. Kinky hair was particularly distinct from the other crimp categories. The kinky crimp category is the most suitable dromedary fiber for the textile industry because its fibers are long, fine, and has the lowest percentage of medullated fibers. Hence, we recommend that selective breeding programs and genetic studies focus on the production of dromedaries with kinky hair fibers.
