Description
技术领域 technical field
本发明属于一种缆绳的编织方法，具体是一种高强度的有特殊应用的超高分子量的聚乙烯纤维系留气球缆绳的编织方法。The invention belongs to a braiding method of a cable, in particular to a braiding method of a high-strength ultra-high molecular weight polyethylene fiber tethered balloon cable with special application.
背景技术 Background technique
当大型气球施放高度超过2000米时，采用普通的钢丝绳强度与重量的关系，不能满足要求，一般采用化纤缆绳，如尼龙，涤纶等。当施放高度超过2000米时，普通化纤缆绳也逐渐不能满足要求，需要采用特种纤维，如芳纶纤维和超高分子量聚乙烯纤维，芳纶纤维因为强度稍低，且不耐紫外线，也只能在特殊场合使用。在这种情形下，超高分子量聚乙烯纤维是最好的选择。超高分子量聚乙烯缆绳虽然目前在各种海上作业和防弹领域应用广泛，但用于系留气球的缆绳，尚未见报道。超高分子量聚乙烯缆绳虽然具有一定的优点，但是缺点也很明显，需要克服。When a large balloon is launched at a height of more than 2000 meters, the relationship between the strength and weight of the ordinary steel wire rope cannot meet the requirements. Generally, chemical fiber cables such as nylon and polyester are used. When the casting height exceeds 2000 meters, ordinary chemical fiber cables cannot meet the requirements gradually, and special fibers such as aramid fiber and ultra-high molecular weight polyethylene fiber are needed. Use on special occasions. In this case, UHMWPE fibers are the best choice. Although ultra-high molecular weight polyethylene cables are widely used in various offshore operations and bulletproof fields, the cables used for mooring balloons have not been reported. Although ultra-high molecular weight polyethylene cables have certain advantages, the disadvantages are also obvious and need to be overcome.
发明内容 Contents of the invention
本发明的目的是提供一种超高分子量的聚乙烯纤维系留气球缆绳的编织方法，其强度较一般的超高分子量聚乙烯缆绳有明显提高。The purpose of the present invention is to provide a braiding method of ultra-high molecular weight polyethylene fiber mooring balloon cables, whose strength is obviously improved compared with common ultra-high molecular weight polyethylene cables.
本发明的技术方案如下：Technical scheme of the present invention is as follows:
超高分子量的聚乙烯纤维系留气球缆绳的编织方法，包括合纱、合小股、浸树脂、编织，其特征在于包括以下步骤：The braiding method of the ultra-high molecular weight polyethylene fiber mooring balloon cable comprises yarn joining, joining small strands, impregnating resin, and braiding, and is characterized in that comprising the following steps:
(1)、合纱，选取7根、纤度为800丹尼尔的超高分子量的聚乙烯纤维，捻合成粗纱，(1), close the yarn, choose 7, fineness is the ultra-high molecular weight polyethylene fiber of 800 deniers, twist synthetic roving,
(2)、合小股，将7根前述合成的粗纱捻合成小股，(2), combined small strands, 7 aforementioned synthetic rovings are twisted into small strands,
(3)、浸树脂，将前述小股浸树脂，并通过小孔拉制，将多余的树脂挤出，(3), impregnating resin, impregnating the aforementioned small strands with resin, and drawing through small holes, extruding excess resin,
(4)、合中股，将3根前述合成的小股捻合成中股，(4), close the middle strand, 3 small strands of the aforementioned synthesis are twisted into the middle strand,
(5)、编织，采用12股编织机编织中股成缆绳，(5), braiding, adopting 12 braiding machines to weave middle strands into cables,
(6)、预拉，在缆绳编织结束后，在树脂尚未干时，在超过缆绳设计的实际使用张力的拉力下，对整条缆绳进行预拉，预拉时间50-60秒，预拉结束后，将缆绳收到绳盘上晾干。(6) Pre-stretching: After the cable braiding is completed, when the resin is not yet dry, under the tension that exceeds the actual use tension of the cable design, pre-stretch the entire cable. The pre-stretching time is 50-60 seconds, and the pre-stretching is over. Finally, the rope is collected on the reel to dry.
预拉的拉力为缆绳设计的实际使用张力的2-3倍。The pre-tensioned tension is 2-3 times the actual tension of the cable design.
在前述合纱、合小股、合中股过程中，保持每根纤维所受张力基本一样，捻距为20-30厘米。In the process of combining yarns, combining small strands and combining middle strands, keep the tension on each fiber basically the same, and the twist length is 20-30 centimeters.
本发明中所述的捻距是指纤维环绕360度的距离。浸树脂步骤中，所用的树脂为水溶性树脂，柔软性好，浸渍缆绳后，随时缆绳干燥，水分脱除，这时树脂附着在缆绳上，起到固定纤维的作用，且有防水功能，但缆绳仍然保持较好的柔软度。The twist length mentioned in the present invention refers to the distance of the fiber around 360 degrees. In the resin impregnation step, the resin used is a water-soluble resin with good flexibility. After impregnating the cable, the cable is dried at any time and the water is removed. At this time, the resin is attached to the cable to fix the fiber and has waterproof function. The cable still maintains good softness.
本发明的优点：Advantages of the present invention:
1、在合纱和合成小股、中股时，具有一定的捻度，这样可以确保单纱的断裂不会将强度的损失传递很远，一般在几个捻距后就没有影响了。同样，单股粗纱的强力损失也不会传递很远。这样，提高了缆绳的整体耐磨性能，即使缆绳表面磨起毛，也不会对强度产生大的影响。1. When merging and synthesizing small and medium strands, it has a certain twist, which can ensure that the breakage of single yarn will not transmit the loss of strength far away, and generally there will be no effect after a few twist lengths. Also, the loss of strength of a single roving does not travel very far. In this way, the overall wear resistance of the cable is improved, and even if the surface of the cable is roughened, it will not have a great impact on the strength.
2、合成小股时，浸树脂，并通过小孔拉制，将多余的树脂挤出，与整条缆绳完工后再浸树脂相比，这样做不但树脂浸入充分，挤出也比较充分，有利于减轻缆绳重量。2. When synthesizing small strands, resin is impregnated and drawn through a small hole to squeeze out excess resin. Compared with impregnating resin after the completion of the entire cable, this method not only fully impregnates the resin, but also fully extrudes, which is beneficial It is beneficial to reduce the weight of the cable.
3、本发明适用于对重量和强度要求较高的场合，例如卷扬机用缆绳等。3. The present invention is suitable for occasions requiring high weight and strength, such as cables for winches.

具体实施方式 Detailed ways
超高分子量的聚乙烯纤维系留气球缆绳的编织方法，包括以下步骤：The braiding method of the ultra-high molecular weight polyethylene fiber mooring balloon cable, comprises the following steps:
(1)、合纱，选取7根、纤度为800丹尼尔的超高分子量的聚乙烯纤维，捻合成粗纱，(1), close the yarn, choose 7, fineness is the ultra-high molecular weight polyethylene fiber of 800 deniers, twist synthetic roving,
(2)、合小股，将7根前述合成的粗纱捻合成小股，(2), combined small strands, 7 aforementioned synthetic rovings are twisted into small strands,
(3)、浸树脂，将前述小股浸树脂，并通过小孔拉制，将多余的树脂挤出，(3), impregnating resin, impregnating the aforementioned small strands with resin, and drawing through small holes, extruding excess resin,
(4)、合中股，将3根前述合成的小股捻合成中股，(4), close the middle strand, 3 small strands of the aforementioned synthesis are twisted into the middle strand,
(5)、编织，采用12股编织机编织中股成缆绳，(5), braiding, adopting 12 braiding machines to weave middle strands into cables,
在前述合纱、合小股、合中股过程中，保持每根纤维所受张力基本一样，捻距为20-30厘米。In the process of combining yarns, combining small strands and combining middle strands, keep the tension on each fiber basically the same, and the twist length is 20-30 centimeters.
(6)、采用特殊的后期处理方法，使缆绳直径固定，外形固定，蠕变减小。具体方法是，在缆绳编织结束后，在树脂尚未干时，采用特殊设计的拉力机，在实际使用时张力的两倍拉力下(此力尚不足破坏缆绳)，对整条缆绳进行预拉，预拉时间60秒。预拉结束后，收到绳盘上晾干。经过预拉，缆绳结构紧固，不易松散，直径基本固定下来，早期蠕变也消除，提高了缆绳的性能。(6) A special post-processing method is adopted to make the diameter and shape of the cable fixed and the creep to be reduced. The specific method is, after the cable braiding is finished, when the resin is not yet dry, use a specially designed tension machine to pre-stretch the entire cable under twice the tension in actual use (this force is not enough to damage the cable), Pre-pull time 60 seconds. After the pre-stretching is complete, it is received on a rope reel to dry. After pre-tensioning, the structure of the cable is tight, not easy to loose, the diameter is basically fixed, and the early creep is also eliminated, which improves the performance of the cable.
