Abstract
The utility model discloses a kind of tug-of-war rope, comprise rope body, it is characterized in that: described rope body is formed by some strand stock twistings, described rope strand comprises nexine and is wrapped in the surrounding layer outside nexine, described nexine is made up of some bursts of polypropylene fiber unit twistings, described surrounding layer comprises some winding units, and described winding unit is mixed sth. made by twisting by polypropylene fiber silk and polyvinyl silk and formed.The program makes tug-of-war rope have good feel and antiskid function.
Description
Technical field
The utility model relates to a kind of tug-of-war rope, belongs to rope field.
Background technology
Tug-of-war rope is the apparatus of people's tug-of-war, and in campus, sports are often used.Tug-of-war rope, due to the palm contacts directly with people, needs it to have good feel, simultaneously in order to prevent rope from sliding on hand, also wants it to have antiskid function.Common tug-of-war rope is normally tied a knot and is prevented rope from sliding on rope, and experience property is poor, and rope is heavier, and feel is poor, and rope coarse causing pricks the hand or galls.
Utility model content
The purpose of this utility model is to provide a kind of tug-of-war rope, makes it have good feel and antiskid function.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of tug-of-war rope, comprise rope body, it is characterized in that: described rope body is formed by some strand stock twistings, described rope strand comprises nexine and is wrapped in the surrounding layer outside nexine, described nexine is made up of some bursts of polypropylene fiber unit twistings, and described surrounding layer comprises some winding units, and described winding unit is mixed sth. made by twisting by polypropylene fiber silk and polyvinyl silk and formed.
Preferably, described rope strand is three strands, and the sth. made by twisting of sub-thread rope strand is twisted with the fingers to for S, and the sth. made by twisting that three strands is twisted rope body is twisted with the fingers to for Z.
Preferably, described nexine is twisted with the fingers and is twisted with the fingers to identical to surrounding layer.
By adopting technique scheme, polypropylene fiber is the trade name of polypropylene fibre, take polypropylene as the fiber that raw material is made by melt spinning, its density is little, intensity is high, and chemical resistance is good, and the interior layer material as rope strand makes the overall material of rope body lighter, polypropylene material moisture pick-up properties difference (hardly moisture absorption), makes rope body easily do simultaneously; Surrounding layer, owing to being the direct skin contact with human body, needs it to have good hygroscopicity and sense of touch.Polyvinyl is the trade name of Pioloform, polyvinyl acetal, is also vinylon, and its performance is close to cotton, and therefore good hand touch is hygroscopicity best material in existing synthetic fiber, has absorbing sweat ability and the little advantage of elongation.But because polyvinyl cost is higher, simultaneously in order to nexine and surrounding layer have good bonding force, adding polypropylene fibre bundle in surrounding layer can form good contact with nexine, is not easy loose.The another kind of benefit having polypropylene fibre and polyvinyl bi-material in surrounding layer is exactly anti-skidding, because hand contacts bi-material simultaneously, avoids the ride comfort of homogenous material, and hand-held being not easy when holding surrounding layer is slided.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Detailed description of the invention
A kind of tug-of-war rope, comprise rope body 1, rope body 1 is formed by some strand stock 2 twistings, the surrounding layer 4 that rope strand 2 comprises nexine 3 and is wrapped in outside nexine 3, nexine 3 is made up of some bursts of polypropylene fiber unit 3a twistings, surrounding layer 4 comprises some winding unit 4a, and winding unit 4a mixes sth. made by twisting by two gangs of polypropylene fiber silk 4a1 and one polyvinyl silk 4a2 and forms.Polypropylene fiber is the trade name of polypropylene fibre, take polypropylene as the fiber that raw material is made by melt spinning, its density is little, intensity is high, chemical resistance is good, nexine 3 material as rope strand 2 makes the overall material of rope body 1 comparatively light, and polypropylene material moisture pick-up properties difference (hardly moisture absorption), makes rope body 1 easily do simultaneously; Surrounding layer 4, owing to being the direct skin contact with human body, needs it to have good hygroscopicity and sense of touch.Polyvinyl is the trade name of Pioloform, polyvinyl acetal, is also vinylon, and its performance is close to cotton, and therefore good hand touch is hygroscopicity best material in existing synthetic fiber, has absorbing sweat ability and the little advantage of elongation.But because polyvinyl cost is higher, simultaneously in order to nexine 3 and surrounding layer 4 have good bonding force, adding polypropylene fiber silk 4a1 in surrounding layer 4 can form good contact with nexine 3, is not easy loose.The another kind of benefit having polypropylene fibre and polyvinyl bi-material in surrounding layer 4 is exactly anti-skidding, because hand contacts bi-material simultaneously, avoids the ride comfort of homogenous material, and hand-held being not easy when holding surrounding layer 4 is slided.
Wherein, rope strand 2 is three strands, and the sth. made by twisting of sub-thread rope strand 2 is twisted with the fingers to for S, and the sth. made by twisting that three strands 2 is twisted rope body is twisted with the fingers to for Z.The polypropylene fiber unit 3a of nexine twists with the fingers to being left-hand lay, and surrounding layer 4 is wound around twisted direction and twists with the fingers to identical with polypropylene fiber unit 3a.Rope body 1 is that the lay pitch that three bursts of modes of twisting with the fingers make rope strand 2 control can be comparatively large, and rope body 1 surface has the sense that just rises and falls, and is more suitable for palm and holds.Twist with the fingers to the outward appearance to rope body 1, feel and performance impact all very large, surrounding layer 4 winding direction is twisted with the fingers to identical with polypropylene fiber unit 3a, and make surrounding layer 4 and nexine 3 form good linear contact lay, institutional framework is more accurate, not easily loose.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
