Abstract

"FIBRAS DE POLIPROPILENO ADEQUADAS PARA TECIDOS NãO-TECIDOS DE FIOS LIGADOS". Refere-se o presente invento a uma fibra para tecidos de fios ligados compreendendo uma composição polimérica de propileno (A) tendo um valor de MFR (MFR (1)) de 6 a 150 g/10 min., e sendo escolhida dentre: i) um copolímero estatístico cristalino de propileno ou uma composição polimérica cristalina de propileno contendo pelo menos 0,8% em peso de etileno e tendo uma temperatura de fusão de 153<198>C ou maior, um teor de fração solúvel em xileno à temperatura ambiente menor que 10% em peso, um valor da razão da fração polimérica coletada na faixa de temperatura de 25<198> a 95<198>C com xileno para a fração solúvel em xileno à temperatura ambiente maior que 4; e ii) uma composição polimérica cristalina de propileno tendo uma temperatura de fusão de 153<198>C ou maior, um teor de fração solúvel em xileno à temperatura ambiente menor que 10% em peso; a dita composição contendo pelo menos 0,64% em peso de unidades recorrentes de etileno e/ou <244>-olefina C~ 4~-C~ 10~ e compreendendo (percentagens em peso): I) de 20 a 80% de um homopolímero cristalino de propileno ou de um copolímero estatístico cristalino de propileno contendo até 1,5% em peso de etileno <244>-olefina C~ 4~-C~ 10~; e 11) de 20 a 80% de um copolímero estatístico cristalino de propileno escolhido dentre: lia) um copolímero cristalino de propileno com de 0,8 a 10% em peso de etileno e/ou IIb) um copolímero cristalino de propileno com de 1,5 a 18% em peso de uma <244>olefina C~ 4~-C~ 10~. dita composição polimérica (A) sendo obtenível por meio de degradação química de uma composição polimérica precursora (B) tendo valores de MFR (MFR (2)) de 0,5 a 50 g/10 min., desde que a razão de MFR (1) para MFR (2) seja de 1,5 a 60. A composição polimérica de propileno (ii) como descrito acima e tecidos não-tecidos que são preparados com ditas fibras. Os ditos tecidos são úteis para coberturas e fraldas.
