Abstract
Abstract A process for the production of metal-plated fibers by electrolessly plating pre-treated fibers, which comprises reeling the fibers into hanks, hanging the fibers in the hank form on a rotary cylinder having projection holes to suspend the fibers in the air, allowing the fibers to move rotatively around the cylinder by rotation of the cylinder, projecting a plating solution at a rate of 5 to 50 cm/sec from said projection holes against the rotatively moving fibers and thereby effecting the electroless plating of the fibers.
