Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

A kind of ultra-high molecular weight polyethylene tug-of-war rope, including rope body 1, rope body 1 is formed by three strands 2 twisting, and the sth. made by twisting of sub-thread rope strand 2 is twisted with the fingers to for S, and three strands 2 is twisted the sth. made by twisting of rope body 1 and twists with the fingers to for Z. In the process producing tug-of-war rope, utilizing rope machine that multiply is first coiled into sub-thread rope strand 2, the rope strand 2 then coiling completed recycles rope machine and is coiled into rope body 1.

When processing, each rope strand 2 is consistent, it is ensured that the stress born between entirety is uniform, does not have and has structural strength and occur the situation such as deformation, fracture not and easily. Rope strand 2 includes nexine 3 and is wrapped in the surrounding layer 4 outside nexine 3, and nexine 3 is made up of some bursts of ultra high molecular polyethylene fiber element 31 twistings, and surrounding layer 4 includes some winding units 41, and each winding unit 41 is formed by the mixed sth. made by twisting of polypropylene and polyvinyl.

The fibre density of ultra high molecular polyethylene fiber is low, and density is 0.97-0.98g/cm3, can bubble through the water column. So making on the total quality of the tug-of-war rope made just light far away and inner core is the tug-of-war rope of steel wire rope. Its extension at break is low, work to break is big, there is the very strong ability absorbing energy, thus there is prominent impact resistance and cutting resistance, in the contrast situation of mutual material, the intensity of ultra high molecular polyethylene fiber is 2.8～4N/tex, and modulus is 91～140N/tex, and its intensity of the same type of material such as polypropylene only has its half, structural strength has breakthrough progress, the tug-of-war rope so made except disclosure satisfy that majority pull out rope except, additionally it is possible to be applied in military training etc. convenient.
