Análise de processos de purga alcalina e enzimática por meio de pesquisa operacional

Abstract

The primary textile beneficiation processes allow the elimination of impurities from textile substrates, preparing them to receive color. The scouring, procedure performed in the primary beneficiation, remove oils, waxes, soluble impurities and dirt particles, increasing the hydrophilicity of the material and, consequently, its quality. The present work aims to compare the quality and procedural costs of alkaline and enzymatic scouring processes using mathematical models of linear programming. The tool used aims to maximize the quantity of goods and services enabling a company’s maximum profit from its available products, through linear programming, which uses profit maximization or cost minimization of Operational Research, in order to find an “optimal” solution. The models were developed using the minimum values of the variables in the recipes, the data tabulated by the companies that supplies the products and were also tested using the Simplex method by the control variables, objective functions and restrictions of each process. Their results were analyzed regarding quality and costs through capillarity tests and minimum recipe costs, which indicated advantageous results for the enzymatic scouring process.
