Determination of dehairing, carding, combing and spinning difference from Lama type of fleeces
Franka1, E.N.; Hick, M.V.H.; Adot, O.

Mixed fleeces as Llama fleeces, require a special textile process known as dehairing. This process behaves differently according to the Lama type of fleeces dehaired. Dehairing generates structural modifications on textile raw material as it eliminates the longer and straighter (coarser) fibres. This has a marked effect on the following worsted or woolen spinning processes. This work was designed for to test these effects with the objective to report how the type of fleeces affects dehairing, worsted or woolen combing and spinning performances. From a textile behavior point of view, a higher fiber diameter variation was detected in double coated fleeces than in luster fleeces. Luster fleeces have a lower bulk potential than double coated fleeces and a lower comb yield due to the higher dehairing effect. It is also this type that produces less ends protruding from the yarn, which may account in part for their diminished prickle effect.
