The monofilament of this invention is a polyamide of polyhexamethylene adipamide oriented from 1.0-4.0 times its original length, has a diameter of 400-1600 microns and contains 2-20 % by weight, based on the weight polyamide of the monofilament, of an alkyl aryl sulfonamide plasticizer and 5.0-40.0 % by weight, based on the weight of the monofilament, of abrasive particles having a particle size of 10-400 microns. These monofilaments are particularly useful as bristles used in brushes that are operated under dry conditions at relatively high temperatures.
L'invention concerne un monofilament composé d'un polyamide de polyhexaméthylène adipamide orienté de manière à atteindre de 1,0 à 4.0 fois sa longueur d'origine. Ce monofilament présente un diamètre de 400 à1600 microns et contient de 2 à 20 % en poids, calculé par rapport au poids de polyamide dans le monofilament, d'un plastifiant sulfonamide d'alkyle-aryle et de 5.0 à 40.0 % en poids, calculé par rapport au poids du monofilament, de particules abrasives présentant une dimension de 10 à 400 microns. Ces monofilaments sont particulièrement utiles en tant que soies pour des brosse utilisées à sec et à des températures relativement élevées.
