El objetivo del estudio fue determinar las características textiles de fibra sucia y tops de alpacas de raza Huacaya color blanco. Se determinó características textiles como: diámetro medio de la fibra (DMF), coeficiente de variación de la media del diámetro (CVMD), factor de confort (FC), factor de picazón (FP), factor de hilado (FH) y longitud de mecha (LM). Se tomaron al azar 30 vellones, 10 por categoría (Extrafina, Fina y Semi Fina) los que fueron categorizados y clasificados por una maestra clasificadora y según la norma técnica peruana (NTP), obteniéndose 77 muestras de fibra clasificada de diferentes calidades (Super Baby (SBL), Baby (BL), Fleece (FS) y Medium Fleece (MFS)). Para determinar las características textiles de la fibra sucia, tops y el control de calidad seempleó el Fiber EC 4.1 siguiendo la norma [IWTO-47-2013], se realizó el contraste de datos entre el...

Alpaca fibre exhibits different quality grades based on fibre diameter and is regulated by the Peruvian Technical Standard – NTP 231.301.2022; however, there are few studies on its cross-sectional characteristics and tensile strength as a function of these different qualities. This study aimed to investigate the cross-sectional characteristics, fibre diameter, and tensile strength in relation to the quality grades. Seven fibre quality groups were established by measuring fibre bundles, and four samples were taken from each group. The cross-sectional characteristics, fibre diameter, and tensile strength were measured using the Fiber Mult, Fiber EC, and Fiber TST devices, respectively. All three variables were affected by fibre quality (p<0.05), showing larger cross-sectional areas and diameters in lower-quality fibres, while tensile strength increased up to quality grade 5 (Fine) bef...
