Wool Characteristics. The processing with which they are produced is combing, a phase that aims to: To carry out this processing, excellent quality yarns are used: they must be light, shiny and highly resistant. The wool of the younger Angora goats, in particular, is used to produce the finest fabrics, whilst that obtained from the adult animals tends to become destined for the production of less valuable products, such as carpets and more resistant fabrics. The wool produced by these special goats ends up in a very fine fiber with about the identical thickness of ultrafine merino and a substantial jump in price. Thanks to its helical structure, in which the keratin is arranged in scales, wool is able to absorb many dyes (both acidic and basic) in a uniform and direct way. Orientate the fibres in the same direction until you get slivers, the working of which produces the fabric. Nature has folded the chemical Thanks to their ability to incorporate a lot of air (which is an insulating element), they adapt to the external temperature and isolate the body, keeping it warm when the external temperature is cold and cool when, on the other hand, the climate is hot.
