Many classes of alpaca fibres contain a certain amount of coarse fibres, which are strong and stiff, and cause discomfort to the end users of alpaca fibre products. It is therefore desirable to separate the coarse alpaca fibres from the fine ones, as it is done with llama fiber. With the AM2 new dehairing technology developed in Argentina, various traits of llama and alpaca fiber were performed similar to those in Australia and in cashmere goats In all cases, samples of raw fleeces were used. The possibility of using worsted (combed and intersected) was planned some time ago. This paper reports on trial results on alpaca dehairing using an modulus of AM2 technology dehairing machine. The diameters of alpaca fleece, dehaired alpaca fibres and removed alpaca fibres were analyzed, and the fibre lengths were compared before and after dehairing. In this dehairing assay, the following input fibre was included: Alpaca fibre top: 22.4 μm average fiber diameter; 23.5% CV of fibre diameter; Objectionable fiber w/w: 6.8%; Nº/weight: 0.32; Fiber of> 30 μm: 6.6%. Average fiber length (down + guard hair: Baer diagram): 111.8 mm. One dehairing Product/Down (passage VI) was obtained: average fibre diameter 21.9μm; 24% CV of fineness; Objectionable fiber w / w: 2.2%; Nº/weight: 0.16; Fiber of > 30 μm: 3.6% Average fiber length (Barbe): 76.6±2.3 mm (reduction: 22%); Hauteur: 72.1±13.2mm (reduction: 10%). Yield at end dehairing was 83.5%. It was concluded that, the dehaired Alpaca product can be processed by the worsted system.
