Dehairing of Patagonian cashmere-bearing goat fleeces: yields and quality characteristics of textile products and by-products
Dehairing is the mechanical separation of coarse fibers, considered contaminants, from fine fibers of high textile value. This process is crucial in the transformation of double-coated animal fibers such as cashmere. This study evaluated the performance of different fleece types (cashmere and cashgo...

| description | Dehairing is the mechanical separation of coarse fibers, considered contaminants, from fine fibers of high textile value. This process is crucial in the transformation of double-coated animal fibers such as cashmere. This study evaluated the performance of different fleece types (cashmere and cashgora) from Creole Neuquina goats during the dehairing stage. Yields, diameters, and the proportion of coarse and fine fiber fractions, as well as fiber lengths before and after dehairing, were compared. The dehairing yield of cashmere was 8.9%, while that of cashgora reached 15.0%. Although the process reduced the coarse fiber content, a considerable proportion remained in the final product (3.8% and 6.6% for cashmere and cashgora, respectively). Expressed as hauteur, the reduction in the initial staple length was 46% in cashmere and 42% in cashgora, resulting in mean values of 26.8 and 27.6 mm. |

El descerdado es la separación mecánica de fibras gruesas, consideradas contaminantes, de fibras finas de alto valor textil. Este proceso es crucial en la transformación de fibras animales de doble capa, como el cashmere. Este estudio evaluó el rendimiento de diferentes tipos de vellón (cashmere y cashgora) de cabras Criollas Neuquinas durante la etapa de descerdado. Se compararon los rendimientos, diámetros y la proporción de fracciones de fibras gruesas y finas, así como las longitudes de fibra antes y después del descerdado. El rendimiento al descerdado del cashmere fue de 8,9%, mientras que el de cashgora alcanzó el 15,0%. Aunque el proceso redujo el contenido de fibra gruesa, una proporción considerable permaneció en el producto final (3,8% y 6,6% para cashmere y cashgora, respectivamente). Expresado como hauteur, la reducción en la longitud inicial de la mecha fue del 46% en el lote cashmere y del 42% en el cashgora, resultando en valores medios de 26,8 y 27,6 mm.
