| Abstract: |
Protective gloves and the like and a yarn comprising a core of a flexible wire alongside an aramid fiber strand or strands and a covering of aramid fiber such as that manufactured and sold under the trademark "Kevlar" by the DuPont Company of Wilmington, Del. in which the aramid fiber is either spun or filament. Two aramid fiber strands, either spun or filament, are wrapped around the core with one strand wrapped in a clockwise direction and the other strand wrapped in a counter-clockwise direction with the opposite spiral wrapping of the strands serving to secure the strands in position on the core without any other securing means. The yarn having a flexible core with aramid fiber strands wrapped thereon is used to make protective gloves on conventional glove knitting or weaving machinery and is capable of movement in relation to needle eyes and the like without jamming in the same manner as various natural and synthetic fiber yarns. The yarn having a flexible core with aramid fiber strands wrapped thereon is also used in making various other products normally made of conventional fiber yarn.
