Laboratory-Scale Determination of the Influence of Temperature, Time, and Mordant on the Tensile Strength and Elongation of Abaca Yarn Dyed with Marco Extract (Ambrosia Peruviana) Subjected to Seawater

Abstract:

In this study, the mechanical properties of tensile strength and elongation of abaca yarn are evaluated. Taking into account the properties of this thread for fish aggregator devices (FADs) used in the fishing industry to attract schools. The dyeing of the yarn was carried out in an Au-toclave HG-TC200B DYEING CONTROLER by the exhaustion method. For dyeing, natural dye, aqueous extract of Marco (Ambrosia peruviana), was used at a concentration of 50% in relation to the weight of the material. The dyeing is done at 80 and 100 ℃, for 60 and 120 min, at a bath ratio of 1:20, with direct mordant using: aluminum and potassium sulfate at 3% and copper sulfate at 3%. To determine the tensile strength and color fastness, the thread was immersed in sea water for 60 days. The results obtained from the resistance were: Initial raw tensile strength 543.36N and exposed to sea water 430.13N. Statistical data analysis is performed with the statistical package STATGRAPHIS®, Centurion XV, version 15.2.05. The results obtained reveal that time and temperature are significantly different (P < 0.05) with a 95% confidence level (P > 0.05).
