Abstract

"PROCESSO DE PRODUçãO DE FIBRAS DE POLIPROPILENO ALTAMENTE RESISTENTES". A presente invenção refere-se a um processo para a produção de fibras de polipropileno altamente resistentes, com uma resistência superior a 6 cN/dtex e uma extensibilidade abaixo de 40%. Para gerar fibras com a maior fineza possível, os cordões de fibras são, inicialmente, extrusados com uma baixa temperatura da massa fundida, abaixo de 250<198>C, e retirados com velocidade de tiragem relativamente baixa, abaixo de 100m/min, concomitantemente ao resfriamento dos cordões de fibras por meio de um fluido refrigerante gasoso. Em seguida, ocorre uma trefilação dos cordões de fibras em, no mínimo, três estágios de estiramento, com uma taxa de trefilação total superior a 4:1, sendo que os cordões de fibras recebem, no primeiro estágio de estiramento, uma trefilação parcial de, no mínimo, 70% da trefilação total. Após a trefilação, os cordões de fibras são cortados nas fibras de polipropileno."HIGHLY RESISTANT POLYPROPYLENE FIBER PRODUCTION PROCESS". The present invention relates to a process for producing highly resistant polypropylene fibers having a strength greater than 6 cN / dtex and an extensibility below 40%. To generate the finest possible fibers, the strands are initially extruded at a low melt temperature below 250 <198> C and withdrawn at a relatively low draft speed below 100m / min concomitantly. cooling the fiber strands by means of a gaseous refrigerant. Fiber strands are then drawn in at least three stretching stages, with a total drawing ratio of more than 4: 1, and in the first stretching stage the fiber strands receive a partial drawing of at least 70% of total drawing. After drawing, the fiber strands are cut into the polypropylene fibers.
