Disclosed is a method for producing a high strength synthetic strength member containing rope capable of being used with powered blocks where such rope has lighter weight and similar or greater strength than steel wire strength member containing ropes used with powered blocks. Disclosed also is the product resulting from such method. The product includes a synthetic strength member, a first synthetic portion and a second synthetic portion. The first synthetic portion is enclosed within the strength member and the second synthetic portion is situated external the strength member. At least a portion of the second synthetic portion also is situated internal a sheath formed about the strength member. The first and second synthetic portions having differing elasticity values, the second synthetic portion having greater elasticity than the first synthetic portion. Preferably, the elasticity of the second synthetic portion is in a range of from 20% to 550% when measured at any temperature within 2°C of 0°C. |
