Resumo: | With the advancement of sustainable actions in the textile industry, biodegradable polymers are considered a potential solution to environmental problems generated by plastic waste. In particular, renewable polyesters, such as polylactic acid (PLA), are the most promising bioresorbable materials for application in consumer areas, such as the textile industry, which is one of the largest segments responsible for waste generation. Based on these considerations, the objective was to investigate the degradability of 3D-printed PLA biopolymer, compared to the degradability of natural and synthetic textile fibers (cotton and polyester). The comparison was carried out with samples of materials degraded in soil and exposed to the weather for 120 days. Significant results were obtained for mass loss, as follows: 13.4% PLA; 8.9% cotton/flat, and 3.84% polyester/flat. As for the loss of area, the results were 46.5% for PLA; 15.4% for cotton/knit; and 6.25% for polyester/knit. The composition of the analyzed materials is one of the factors that can determine the period of degradation, since natural fiber fabrics present faster decomposition due to the presence of microorganisms. Another point to highlight is the material construction, as the knitted fabric is more unstable compared to flat fabric, its bonds tend to break more easily resulting in a different degradation process for flat, knit, and non-woven materials. |

Os poliésteres renováveis como o ácido polilático (PLA), particularmente, constituem os materiais bioreabsorvíveis mais promissores para aplicações nas áreas de consumo, como a indústria têxtil, um dos maiores segmentos responsáveis pela geração de resíduos. Com base nessas considerações, objetivou-se investigar a degradabilidade do biopolímero PLA impresso em 3D, comparado à degradabilidade das fibras têxteis naturais e sintéticas (algodão e poliéster). O comparativo foi realizado por meio de amostras dos materiais degradadas em solo e expostas às intempéries por 120 dias. Foram obtidos resultados significativos para a perda de massa, sendo: 13,4% PLA; 8,9% algodão/plano e 3,84% poliéster/plano. Já para a perda de área se obtiveram 46,5% PLA; 15,4% algodão/malha e 6,25% poliéster (malha). Observou-se que a composição dos materiais analisados é um dos fatores que pode determinar o período de degradação, pois os tecidos com fibras têxteis oriundas de fontes naturais apresentam decomposição mais rápida em razão da presença de microrganismos. Outro ponto a destacar é a construção dos materiais: observou-se que pelo fato de a malha ser mais instável comparada ao tecido plano, suas ligações tendem a se romper com mais facilidade, resultando em um processo de degradação diferente para os materiais plano, malha e não tecido.Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)2022-07-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/xmlhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/119210.5327/Z2176-94781192Revista Brasileira de Ciências Ambientais (RBCIAMB); v. 57 n. 2 (2022): RBCIAMB - ISSN 2176-9478 - Junho; 302-319Revista Brasileira de Ciências Ambientais (RBCIAMB); Vol. 57 No. 2 (2022): RBCIAMB - ISSN 2176-9478 - June; 302-3192176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESenghttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/1192/779https://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/1192/813Copyright (c) 2022 Brazilian Journal of Environmental Sciences (Online)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessdo Bem, Natani AparecidaReitz Cardoso, Flávia Aparecidade Souza Paccola, Edneia AparecidaSoto Herek Rezende, Luciana Cristina2023-11-09T17:38:43Zoai:ojs.www.rbciamb.com.br:article/1192Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2023-11-09T17:38:43Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false |
