    摘要： This invention claims a stitched double layer composite hose and manufacturing method thereof, comprising a middle fabric pipe layer, an inner surface composite colloid material layer and an outer surface composite colloid material layer. The structure of said fabric pipe layer is weft-stitched double-layer unit structure; said double-layer unit structure comprises an outer layer, an inner layer and stitched wefts, and said inner layer comprises inner layer warps and inner layer wefts; said outer layer comprises outer layer warps and outer layer wefts. The stitched wefts interweave with outer layer warps and inner layer warps, conjoining inner layer and outer layer together. The fabric pipe layer weaved according to this invention solves problems of the stitched double layer composite hose in the fabric pipe layer of traditional casing, with such advantages as high flexibility, less weaving point, less loss of yarn strength and less degree of torsion. The fabric pipe layer, with special coating equipment and special coating process, can be directly processed into a stitched double layer composite hose satisfying market needs with large caliber, high dielectric strength and higher flexibility. The production process is simple, featured with extremely high utility value and worthy of promotion for production.

    摘要翻译： 本发明提供一种缝合双层复合软管及其制造方法，包括中间织物管层，内表面复合胶体材料层和外表面复合胶体材料层。 所述织物管层的结构为纬编双层单元结构; 所述双层单元结构包括外层，内层和缝合的纬线，所述内层包括内层经线和内层纬线; 所述外层包括外层经线和外层纬线。 缝合的纬线与外层经线和内层经线交织，将内层和外层连接在一起。 根据本发明编织的织物管层解决了传统套管织物管层缝合双层复合软管存在的问题，具有柔韧性高，织造点少，纱线强力损失少，扭转程度小等优点。 织物管层采用特殊的涂布设备和特殊的涂布工艺，可直接加工成满足市场需求的大口径，高介电强度和高柔韧性的缝合双层复合软管。 生产工艺简单，具有极高的实用价值，值得生产推广。
