Abstract
In an electric cable or other elongate body, a tubular textile braid comprises two sets of yarns each made up of a plurality of synthetic monofilaments, the yarns of the two sets extending in opposite directions around the axis of the braid corresponding to upper and lower yarns in the braiding machine differing in twist to an extent such that the more twisted yarns have their tensile strength increased by at least 10% but do not have their cover in the braid decreased by more then 25%, both by comparison with an otherwise identical yarn having the same twist of those of the ess twisted set. Preferably the twist in the upper yarns is zero. The invention allows higher production speed and reduced down-time without significant loss of cover, because the small extra twist in the lower yarns gives them better abrasion resistance to withstand passage through their greater exposure in the braiding machine.
