Abstract

<B>PROCESSO PARA FABRICAçãO DE FILAMENTOS COM DENIER ELEVADO DE POLìMEROS CRISTALINOS LìQUIDOS TERMOTRóPICOS E SUAS COMPOSIçõES<D> A presente invenção revela e reivindica um processo novo para a formação de filamentos como fiado e tratado a quente com denier elevado de um polímero cristalino líquido termotrópico. As modalidades preferidas incluem processo para a formação de monofilamentos como fiados e tratados a quente de alguns poliésteres e poliesteramidas totalmente aromáticos. O processo envolve a) aquecimento de um polímero cristalino líquido termotrópico até acima de sua temperatura de transição de fusão; b) passagem do referido polímero fundido através de uma câmara de extrusão equipada com um capilar de extrusão que tem uma razão de aspecto maior do que aproximadamente 1 e menor do que aproximadamente 15 para formar um filamento; e c) enrolamento do filamento em uma razão de estiramento de pelo menos aproximadamente 4. Os filamentos assim formados são de pelo menos 50 denier por filamento (dpf) e apresentam orientação molecular essencialmente uniforme em seção transversal. Em uma etapa opcional final, os filamentos são tratados a quente em etapas para formar filamentos que apresentam propriedades de tração excelentes. Os filamentos tanto como fiado quanto tratados a quente apresentam propriedades de tração notavelmente boas, mantendo pelo menos 80 a 90% das propriedades esperadas dos filamentos convencionais com denier baixo (5 a 10 dpf).
