Abstract

Una composicion de polipropileno termoplástica derretida-extruible que tiene una tasa de flujo de derretido en un rango de desde alrededor de 18 a alrededor de 30 g/10 minutos a una temperatura de 190 degree 8C y a una carga de 2.16 kg, una polidispersabilidad de menos de 4, y un peso molecular promedio-Z mayor de 300,000 como se determino mediante refractometría diferencial. La composicion puede incluir un primer polipropileno termoplástico teniendo una tasa de flujo de derretido más baja de 18 g/10 minutos a una temperatura de 190 degree C y a una carga de 2.16 kg y un segundo polipropileno termoplástico teniendo una tasa de flujo de derretido superior a 18 g/10 minutos a una temperatura de 190 degree C y a una carga de 2.16 kg. La proporcion por peso del primer polipropileno al segundo polipropileno está en un rango de desde alrededor de 90;10 a alrededor de 10:90. La composicion puede incluir de desde alrededor de 0.1 a alrededor de 1 por ciento por peso, basado sobre el peso de los polipropilenos termoplásticos primero y segundo, de un polisiloxano de alquilo sustituido definido. También se proporciona un método para formar un tejido no tramado cuyo método incluye el combinar la composicion de polipropileno termoplástico derretido-extruible compuesta del polipropileno termoplástico primero y segundo como se describio arriba. La composicion termoplástico compuesta es derretida-extruida a través de una matriz para formar fibras continuas. Las fibras continuas son enfriadas a un estado solido, se jalan o se atenuan, y se depositan al azar sobre una superficie foraminosa movil como un tejido de fibras enredadas. La composicion puede incluir el polisiloxano de alquilo sustituido.
