Mejora de las características funcionales del papel higiénico triple hoja en el proceso de rebobinado a través de la metodología DMAIC

Abstract

This research project presents the analysis of results achieved through the application of the DMAIC methodology in the tissue manufacturing process in order to improve problems related to Quality, such as non-compliance with the critical variables of triple-sheet toilet paper, such as the resistances , even though when initially analyzed it presents data with a tendency towards the lower limit and below the standard, continuously generating PNC and complaints from external clients frequently in the process. Using the DMAIC methodology, a diagnosis of the data was prepared in the period 2022 to determine the causes that generate non-compliance with the critical variables of triple sheet toilet paper using statistical tools, subsequently 3 alternatives were proposed to solve the problem which were analyzed. and was selected for the option with the best benefit-cost ratio. Regarding the results, at the beginning of the research there are Cp process capacity indices. 0.99 and Cpk. of 0.25 for the variable resistance of triple sheet toilet paper and using the DMAIC methodology an increase in Cp is achieved. at 1.20 and Cpk. to 1.09, achieving stability in the behavior of the resistance variables with respect to the objective in the process. The use of the DMAIC methodology allowed us to analyze and improve process control through its 5 stages, identifying errors in the methods and activities carried out, establishing strategies that contribute to continuous improvement within the study process.
