| description | In order to provide stretched fibers formed from a polypropylene, which have excellent thermal creep resistance, break strength and stiffness, a production method according to the present invention is characterized by comprising a step wherein fibers for stretching, said fibers containing a homopolypropylene that satisfies the requirements (1)-(3) described below, is stretched at a stretch ratio of 7 times or more under such conditions that the stress during the stretching is from 80 MPa to 10,000 MPa (inclusive). (1) The mmmm fraction is 97% or more. (2) The molecular weight distribution (Mw/Mn) as obtained by GPC is less than 3.0. (3) The melt flow rate (230°C, 2.16 kg) is 1-100 g/10 min.
Afin d'obtenir des fibres étirées formées d'un polypropylène, qui présentent d'excellentes résistance au fluage thermique, résistance à la rupture et rigidité, la présente invention concerne un procédé de production selon la présente invention étant caractérisé en ce qu'il comprend une étape dans laquelle des fibres pour étirage, lesdites fibres contenant un homopolypropylène qui satisfait aux exigences (1) à (3) décrites ci-dessous, sont étirées à un rapport d'étirage de 7 fois ou plus dans des conditions telles que la contrainte pendant l'étirage est de 80 MPa à 10 000 MPa (inclus). (1) La fraction mmmm est de 97 % ou plus. (2) La distribution de poids moléculaire (Mw/Mn) telle qu'obtenue par GPC est inférieure à 3,0. (3) L'indice de fluage (230 °C, 2,16 kg) est de 1 à 100 g/10 min.
