“…Hand-dehairing has demonstrated its feasibility [27], although the process is only efficient with double coated and intermediate coated fleece [28]. However, a recent work has shown that the per person and per hour yield is 9.9±1.1 g/person/h, which renders it economically unviable [29].…”

In this minireview it is to analyze the physical attributes that determine the comfort of fabrics made of South American Camelid fibers (Lama and Alpaca), discuss the effect on their textile value and evaluate an possible approache on their possible mechanical solutions. Taking the distribution of all fibers do not respond to a normal distribution, but the different fiber types identified by the type of medulla, they do respond to a normal distribution. While emphasis has always been on mean fiber diameter, the fiber frequency exceeding 30 microns (objectionable fibres) has a key role in quality. This is essential for light fabrics, where the effect of prickle plays a critical part in consumer´s choice. Dehairing, as a mechanical way, provides an immediate solution, though excessive fiber breakage should be addressed. It is concluded that the textile fiber quality of South American Camelids is promissory if the presence of objectionable fibers is solved, resulting in a tolerable frequency for consumers (<3%). This implies a true paradigm shift with regard to the classic textile processing of Alpaca and Lama fibers (from worsted to woolen system). This would enhance the fiber softness to touch, together with other important features that would render the fiber price more competitive. Mini-review Article

In this paper we intends to analyze the physical attributes that determine the comfort of fabrics made of South American Camelid fibers (Lama and Alpaca), the effect on their value and their possible mechanical and/or genetic solutions. While emphasis has always been on mean fiber diameter, the fiber frequency exceeding 30 microns has a key role in quality. This is essential for light fabrics, where the effect of prickle plays a critical part in consumer´s choice. Yet the genetic solution of the problem lies in the slow selection response. Dehairing provides an immediate solution, though excessive fiber breakage should be addressed. It is concluded that the textile fiber quality of South American Camelids is promissory if the presence of objectionable fibers is solved, resulting in a tolerable frequency for consumers (<3%). This process could be explored via genetic selection or applying dehairing

“…La separación manual de fibra gruesa del vellón fino usualmente lo realizan las maestras descerdadoras (Sacchero y Mueller, 2005). Las cerdas se pueden orientar a la elaboración de alfombras, almohadas y sogas a nivel local, abriendo nuevas fuentes de empleo que generaría más ingresos económicos para las familias andinas (Quispe et al, 2015).…”

El objetivo de la investigación fue determinar la variación de las características textiles y longitud de fibra al descerdado manual del vellón de vicuña, así como evaluar la influencia del sexo, edad, sitio de muestreo del vellón, y lugar de procedencia de la vicuña sobre las características de calidad de la fibra. El descerdado manual se realizó en 77 muestras de vicuñas provenientes de tres provincias del departamento de Apurímac, Perú. Las características textiles de la fibra antes y después del descerdado fueron evaluadas usando el equipo OFDA 2000 y mediante el análisis de varianza, prueba de t y Tukey (α=0.05). La calidad de fibras descerdada es superior a la fibra no descerdada, debido a la reducción del diámetro medio de fibra (DMF) (-1.68 μm), desviación estándar de DMF (DE) (-0.73) y finura al hilado (FH) (-1.27 μm) y al incremento del porcentaje de fibras <30 µm (FC) (1.12%) y de la curvatura media (CU) (6.75°/mm). En fibra descerdada los juveniles tienen un DMF más fino (12.24 μm) que las adultas (13.01 μm), el DMF del costillar medio es más fino (12.39 μm) respecto a paleta (12.81 μm) y grupa (12.77 μm). Asimismo, se encontró variación de las características textiles (DE, CV, FC, y CU) y longitud de fibra entre los vellones de las tres provincias de Apurímac. En conclusión, el descerdado manual reduce el diámetro medio de fibra y su desviación estándar, y aumenta la curvatura media y el confort de la fibra, mejorando las propiedades de calidad y uniformidad del hilo.
