<p>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.</p> |
