Abstract

MATERIAIS NÃO TECIDOS E FIBRAS, INCLUINDO MATERIAIS POLIMÉRICOS À BASE DE AMIDO. São descritos materiais à base de amido de peso molecular muito alto (por exemplo, mais de 2 milhões, como 3-20 milhões g/mol) e formulações incluindo os mesmos, que podem ser fiadas em processos de fiação contínua, sopro em fusão, fio ou processos similares. Mesmo com pesos moleculares tão altos, as formulações podem ser processadas em velocidades de linha comerciais, com viscosidades de cisalhamento de fieira de 1000 s-1, sem início de instabilidade de fluidez. O material à base de amido pode ser misturado com um ou mais materiais termoplásticos que têm valor (ou valores) de índice de fluidez mais altos, que servem como diluente e plastificante, permitindo que o componente à base de amido muito viscoso seja fiado sob tais condições. As características particulares do índice de fluidez do material diluente termoplástico podem ser selecionadas com base no tipo de processo que está sendo usado (por exemplo, fiação contínua, sopro em fusão, fio, etc.). O material à base de amido pode exibir alta sensibilidade ao cisalhamento, comportamento de endurecimento por tensão e/ou tensão de cisalhamento crítica muito alta (por exemplo, pelo menos 125 kPa).NON-WOVEN MATERIALS AND FIBERS, INCLUDING STARCH-BASED POLYMERIC MATERIALS. Starch-based materials of very high molecular weight (e.g. more than 2 million, such as 3-20 million g/mol) and formulations including the same, which can be spun in continuous spinning, melt blowing, wire or similar processes. Even at such high molecular weights, the formulations can be processed at commercial line speeds, with die shear viscosities of 1000 s-1, without the onset of flow instability. The starch-based material may be blended with one or more thermoplastic materials having a higher melt flow value (or values), which serve as a diluent and plasticizer, allowing the very viscous starch-based component to be spun under such conditions. conditions. The particular melt index characteristics of the thermoplastic diluent material can be selected based on the type of process being used (eg, continuous spinning, melt blowing, wire, etc.). Starch-based material may exhibit high shear sensitivity, stress hardening behavior and/or very high critical shear stress (e.g. at least 125 kPa).
