Abstract

Patente de Invenção para <B>"FIBRA DE POLITETRAFLUORETILENO"<D>. Uma fibra de PTFE que é adaptada para ser costura em altas velocidades. A fibra apresenta uma dureza maior do que cerca de 0,36 gramas por denier (g/d). Uma faixa para a dureza é de cerca de 0,36 a cerca de 1,01 g/d, com uma faixa preferida de cerca de 0,50 a cerca de 0,80 g/d. A dureza da fibra de PTFE da invenção é mais preferivelmente cerca de 0,60 g/d. A fibra da invenção apresenta uma tensão de engenharia de pico maior do que cerca de 1,6 g/d, e um esforço de ruptura maior do que cerca de 15,5%. Uma faixa preferida para a tensão de engenharia de pico é de cerca de 3,0 g/d a cerca de 5,0 g/d, e uma faixa preferida para o esforço de ruptura é de cerca de 20 por cento a cerca de 50 por cento. Mais preferivelmente, a tensão de engenharia de pico é cerca de 4,4 g/d, e o esforço de ruptura é cerca de 24 por cento. Em outro aspecto, esta invenção proporciona um processo para fabricação de uma fibra que envolve a provisão de uma fibra de PTFE, e aquecimento da fibra de PTFE à uma temperatura de cerca de 300°C a cerca de 500°C, enquanto super-alimenta a fibra em um super-alimentador de até cerca de 70%. Uma faixa preferida para a temperatura é de cerca de 350°C a cerca de 450°C, e uma faixa preferida para o super-alimentador na etapa de super-alimentação é de cerca de 10 por cento a cerca de 20 por cento. Mais preferivelmente, a temperatura na etapa de aquecimento é de cerca de 400°C, e o super-alimentador na etapa de super-alimentação é de cerca de 15 por cento. A fibra de PTFE pode ser usada como um filamento para um fio dental aperfeiçoado, e é também adequada para um material de suporte aperfeiçoado.
