Caracterización de las propiedades físico- mecánicas de fibra e hilo de alpaca suri (Vicugna pacos) de la Estación Experimental Aña-Moyocancha

Abstract

The aim of this study was to perform the physical-mechanical characterization of suri alpaca (Vicugna pacos) fiber and yarn from the Aña-Moyocancha Experimental Station. A completely randomized test was used, and means were separated using Duncan’s test (p ≥ 0.05). A sample of 3000g of suri alpaca fiber was taken according to body area (ten), age (young and adult), and sex (females), with three replicates for each analysis. In the fiber characterization, the following physical properties were evaluated, obtaining the following results: relative length (I: 28.83cm), absolute length (I: 33.38cm), diameter (A: 35.67 µm), curls per inch, and medullation (61.11%). Regarding the mechanical properties, the characteristics and means obtained were as follows: count (0.17mm), lastometry (0.22mm), elongation (0.29%), and tensile strength (515.56 N/cm2). The measurements showed that suri alpaca fiber falls into the quality categories between fleece and coarse. The body areas showed that the most representative length characteristics was the flank area, and the dorsal part of the neck was the least coarse. There were no differences in the number of curls per inch and medullation. Age influenced the number of curls per inch and diameter. The quality of suri alpaca yarn from the study is not suitable for textile processes since it does not meet the required minimum values.
