| Sumario: | [EN] The search for more sustainable and less polluting alternatives for the textile industry has led to exploring the use of natural and organic pigments for dyeing fabrics. The objective of this research is to analyze the formation of nano pigments with annatto extract for use in 100 % cotton dyeing. The scientific methods used were experimental and observation; in addition, several qualitative techniques are used. For the extraction, dynamic maceration, rotavapor, and separation with hydroxides were performed. A random sample of the extracts was taken and, for convenience, the homogeneous mixture was made with the nano clay, where the nano pigments were obtained through a synthesis process in which hydrated clay of Trimethyl Stearyl Ammonium was used as a support and organic annatto molecules were inserted. Sub-sequently, several cotton samples were dyed using a recipe, and then washed. The nano pigments obtained were characterized by various techniques, such as scanning electron microscope (MEB or SEM). The color fastness to washing was evaluated with the spectrophotometer and the Delta-E was obtained using the Cie94 calculator. Among the SEM findings of the sample Co_9 Trimethyl + P, it has a titration (2) = presence of Nanopigment (NP), with a reddish-orange brick color with (¿E = 58.61). The opposite is true for the sample Co_5 Trimethyl + R, which is valued as (1) = reduced presence of Nanodye NC, and has a very weak pale yellowish color (¿E = 3.46). The solidity of the dye was evaluated and the dry and wet rubbing was also valued with the scale of grays. Likewise, the average pigment yield is 9.09 % and the dye is 9 %, obtaining results in terms of solidity 1 and color change 5 in fabrics dyed with solid pigment, in contrast to the low fastness in fabrics with a liquid dye. Therefore, it is concluded that the annatto nano pigments obtained are a viable and sustainable alternative for textile dyeing and its application in the textile industry. |
