发明内容
本发明的目的在于提供一种具有接结双层结构中间层管坯的双层复合软管及其制造方法，以解决双层套管中间层管坯的双层复合软管所存在的问题。

第二方面，本发明还提供了一种如前述的双层复合软管的制造方法，其包括下列步骤：
中间层管坯的织造：首先，根据单个完全循环组织的经线数、完全循环组织的循环个数确定中间层管坯中的经线总数量；然后，设定经线总数量，同时分别编织中间层管坯的内层和外层，并通过接结纬线与内层与外层交织，使内层和外层接结成一体，形成中间层管坯；
胶体复合：在所述中间层管坯的内外表面一次共挤涂覆胶料，或内表面涂覆粘合胶 料，外表面涂覆粘合剂色浆双面成型。
作为优选方案，所述中间层管坯的编织结构为双层斜纹结构或双层平纹结构，中间层管坯中的经线总数量分别按如下方式确定：
当编织结构为双层斜纹接结时，编织结构由n个完全循环组织编织而成，每个完全循环组织的经线数量为6，所述中间层管坯中的经线总数量为6n+4。
当编织结构为双层平纹接结时，编织结构由n个完全循环组织编织而成，每个完全循环组织的经线数量为4，所述中间层管坯中的经线总数量为4n+2。
作为优选方案，所述一个完全循环组织，其采用如下编织方式：使用设定个数的梭子在编织机械上的同步圆周运动带动纬线，使所述纬线穿梭于已分层的经线之间进行编织，在同一个编织循环中与设定个数的分线盘配合分经，使梭子带动纬线穿过已分层的经线来完成把内层与外层织物连接起来，从而完成中间层管坯的编织。

本专利研发生产的高强度纤维双层接结复合软管，其中间层管坯是利用专门的编织机械在编织内外层的同时通过一纬线接结把相对独立的内外层编织组合成一个整体软管织物，使织物平整、柔软，生产出的复合软管承压能力大幅提高，彻底解决了大口径复合软管承压力低的难题，且水流阻力小。其成品耐磨性大大提高，外表保护层磨损后还有双层接结的中间层管坯外层来保护里层，而不至于衬里层泄露。即使在双层接结的中间层管坯外表面不涂覆任何保护层其高强度的外层同样起到保护内层的作用，所以本发明专利一种高强度纤维双层接结复合软管尤其适用于野外气、液介质的远距离输送，具有较为广泛的应用前景。
本发明的编织原理为：使用设定个数的梭子在编织机械上的同步圆周运动带动纬线，使所述纬线穿梭于已分层的经线之间进行编织，在同一个编织循环中与设定个数的分线盘配合分经，使梭子带动纬线穿过已分层的经线来完成把内层与外层织物连接起来，从而完成软管中间层管坯的编织。
该织造方法与双层套管中间层管坯的主要区别在于：
1、一个完全循环组织的经线数是单层管的一个完全循环组织的经线数的双倍，一个完全循环组织的纬线数是单层管的一个完全循环组织的纬线数的三倍；
2、如将已编入的接结纬线拆除，仍有两个完整的相对独立的内外织物层；
3、纬线数的增加可极大地提高中间层管坯的耐压力和耐磨性；
4、接结双层中间层管坯柔软，延伸及膨胀系数低，扭转度小。
本发明的有益效果是：
1、织造的中间层管坯克服了传统双层套管中间层管坯的双层复合软管所存在的问题；
2、纬线数的增加可极大地提高中间层管坯的耐压力和耐磨性；
3、具有使用寿命长，柔软性好、交织点少、纱线强度损失小、扭转度小的优点；
4、中间层管坯再通过专用的涂覆设备和专门的涂覆生产工艺就能直接生产出满足市场需要的大口径、高耐压、较柔软的双层复合软管，生产工艺简单，具有极高的实用价值及很好的生产推广性。
