A method for manufacturing wet absorption yarns comprises the following steps of fabricating the polypropylene filaments into yarns; feeding the yarns to a false twisting machine for twisting the yarns; feeding the yarns to a driving roller and a package rollers for twisting the yarns to be as twisting yarns; transferring the twisting yarns to at least one brush roller with short brushes on the surface of the roller so that hairs are formed on the twisting yarns to be as haired twisting yarns; feeding the haired twisting yarns to at least one grooved roller; feeding the haired twisting yarns to at least one guiding wheel to be stretched and drying the haired twisting yarns; and outputting the haired twisting yarns as wet absorption yarns. Moreover, a wet absorption yarns is disclosed, where wet absorption yarns made from polypropylene filaments. The wet absorption yarns is twisted, haired and permeated with wet absorber.

In order to increase the cracking corrosion resistance of a wire under stress compressive stresses are introduced through surface treatment by brushing, on the apparent surface of the wire. A system and method are notably applied for the manufacture of wire-reinforced flexible pipes. The reinforcing wires are subjected to a surface treatment by brushing after setting the wires on the flexible pipe.
