About the Book

A natureza, na sua abundância, oferece-nos uma grande quantidade de materiais que podem ser considerados como materiais fibrosos. O estudo de uma nova fibra tunisina, extraída da planta Typha, será o objetivo deste trabalho. Começámos por fazer um estudo bibliográfico sobre os diferentes métodos de extração das fibras vegetais. Seguiu-se uma apresentação da planta Typha e da sua importância económica. De seguida, estudou-se a influência dos parâmetros de extração no rendimento, densidade linear, diâmetro, tenacidade e teor de lenhina das fibras de Typha. O método de conceção experimental foi utilizado para identificar as condições de extração óptimas. O estudo estatístico utilizando a superfície de resposta e a função de desejabilidade determinou as condições óptimas de extração. Foi determinada a morfologia das fibras e os constituintes químicos obtidos. As fibras extraídas dos caules de Typha têm um teor de lenhina de aproximadamente 22,05% e um valor de alfa-celulose de aproximadamente 51,3%.
