Abstract: The component of α protein of Shatoosh fibre and hair were composed of 20 kinds of amino acids, same as other wool or cashmere, but the content of each amino acid was different. The content of glutamic acid in Shatoosh fibre was 3 percents higher than which was in the hair, while Histidine and Cystine were only 66% and 15.48% to the hair. The content of Histidine in Shatoosh fibre was 5.88%, which was 4 percents higher than other wool or cashmere. The content of Cystine was 10.60%, the highest among experimental samples, which would be embodied the excellent fiber quality and textile performance.The amount of alkali amino acid was close to acid amino acid was found in Shatoosh, which suggested that Shatoosh has strong capbility to resist alkali and acid solution, microorganism etal. The ratio of Paa to Daa was less than 1, which confirmed the point came from alkali and acid amino acid again.
