Uso da ferramenta Dmadv para criação de protótipo de Sandbag de meta-aramida e aplicação de teste de biodegradabilidade

Abstract

This work proposes the use of textile structures made of meta-aramid fibers in an application of an environmental nature (forest fires), from a subtype of geotextile structures defined as sandbags. The model was developed, theoretically, with a basis for the development of prototypes / new products based on the confection DFSS (design for six sigma) though DMADV methodology and, experimentally, through circular knits composed of 100% meta-aramid yarns 20 and 30 tex. Each yarn count built individual knits and they were cut to dimensions of 15x10 cm and transformed into bags. The central purpose of the work is to analyze what happens with some performance parameters of these fibers and structures after being exposed in uncontrolled natural conditions and to base their application in macro character, from the model developed in the prototype.
