摘要
An aramid yarn, preferably poly(p-phenylene terephthalamide), is coated with a water swellable superabsorbent material. The swelling value of the yarn is at least 60. The superabsorbent provides water blocking capability to the yarn, so that it is suitable for use as a strength member in water tight optical communication cables.;The yarn is made by successively treating an aramid yarn with a water-in-oil emulsion, a superabsorbent material being present in the water phase of the emulsion, and removing the liquid components from the treated yarn by evaporation.
