Description

Technical Field

[0001] The utility model relates to a double - layer cylindrical cloth with side seams, and belongs to the technical field of cylindrical cloth. Background Art

[0002] Cylindrical cloth is quite common in both life and production, such as fire hoses, and cloth tapes used in fine spinning of yarns, etc. However, for shock absorption and heat preservation, a double - layer cylindrical cloth is required. For example, for transportation, a shock - proof double - layer cylindrical cloth is needed for protection. For example, for heat insulation while preventing scalding, a double - layer cylindrical cloth is needed. However, ordinary cylindrical cloths are mostly woven by shuttle looms. But for double - layer cylindrical cloths, because there is a velvet interlayer in the middle, the weaving is relatively complex, and it is difficult to use a shuttle loom for weaving. Instead, it is relatively simple to use a double - shed double - rapier loom for weaving. However, since the weft yarns are woven in one by one, such cylindrical cloths will have side seams. How to design a double - layer cylindrical cloth with side seams has become a problem to be solved. Content of the Utility Model

[0008] The lower - half - circle surface layer is formed by the interweaving of lower - half - circle surface - layer warp yarns and weft yarns, and the lower - half - circle inner layer is formed by the interweaving of upper - half - circle inner - layer warp yarns and weft yarns.

[0009] On the basis of the above - mentioned scheme and as the preferred scheme of the above - mentioned scheme: the left - hand side seam is formed by the interweaving of 8 left - hand side - seam warp yarns and weft yarns, and the right - hand side seam is formed by the interweaving of 8 right - hand side - seam warp yarns and weft yarns.

[0010] On the basis of the above solution and as a preferred solution of the above solution: the left end connection of the upper half-round cylinder cloth and the lower half-round cylinder cloth is connected by the left connecting pile warp.

[0011] On the basis of the above solution and as a preferred solution of the above solution: the right end connection of the upper half-round cylinder cloth and the lower half-round cylinder cloth is connected by the right connecting pile warp.

[0012] On the basis of the above solution and as a preferred solution of the above solution: the warp yarns and weft yarns are high-strength core-spun yarns, the high-strength core-spun yarns include core yarns and wrapping filaments, the core yarns include ultra-high molecular weight polyethylene filaments, and the wrapping filaments are polyester filaments.
