Utilización de cremor tártaro en la elaboración de tinte de subproducto de matadero para el teñido de fibra de alpaca

Abstract

This experimental study aimed to combine different levels of cream of tartar (5%, 10%, and 15%) with byproduct dye (hemoglobin) obtained from bovine blood for dyeing alpaca fiber. The research was conducted at the Escuela Superior Politécnica de Chimborazo, Faculty of Animal Sciences, in the Fiber Agro-Industrial Laboratory. The alpaca fiber used in this study came from the Aña Moyocancha experimental station and was processed from raw fiber to dyed yarn. The methodology in this study included a completely randomized design (CRD). The experimental units comprised 250 grams of alpaca fiber yarn in skeins, distributed into four treatments with four replications, totaling 4000 grams of alpaca fiber yarn (4 kg). The variables in this study included pH and refractive index in the dye and the yarn. Other variables also included lightfastness (on a 5-point scale), tensile strength (N/cm2), elongation (%), and cost-benefit analysis ($). The physical-chemical analyses of the dye revealed the highest refractive index value (1.23) and a pH of 4.43 when using 15% cream of tartar. Considering the physical-mechanical tests, the highest values were reported for lightfastness (5 points), tensile strength (10,067.19 N/cm2), elongation (33.93%), and a cost-benefit ratio of $1.20. In conclusion, the concentration of 15% tartar cream demonstrated the best attributes for yarn quality since it yielded higher results in the physical-chemical properties of the dye and the physical-mechanical properties of the yarn. Additionally, it is recommended to conduct a feasibility study regarding the use of this concentration of cream of tartar.
