Amaranto y nogal para el teñido de la fibra de alpaca.

Abstract

The objective of this bibliographic project was to compare which of the organic dyes Amaranth (Amaranthus Hypochondriacus) and Walnut (Juglans Regia) is the most suitable, to dye according to the quality requirements of alpaca fiber, for which the necessary information from the bibliographic sources of sites such as DSpace, Scielo, Scoopus, and others. The exclusion criterion of the results was based especially on the year of publication which should not be more than 5 years. The results express that the application in the dyeing of the alpaca fiber products of organic origin, constitutes a friendly technology with the environment. In the evaluation of the physical resistances, they established the highest resistance to tension 1128.03 N / cm2, and solidity to rubbing (5 points) when applying natural extract of walnut. While the best light fastness was determined with the amaranth extract with a score of 4.75 points and in the sensory evaluation of color intensity, the best response was obtained by the batch of fibers to which extract of amaranth with a 5.00-point rating considered excellent, and which is a reference to consider that the natural dye has entered up to the medullary part of the fiber and has not leached. In the same way, the highest profitability is determined in the alpaca fibers dyed with walnut extract, the amount determined for the expenses during the dyeing process was $10.26, while the income was $ 15.50, which represents a benefit ratio - cost of 1.51, that is to say that there is a profit of 51%.
