The utility model discloses a cut-figured cloth, which comprises an upper base cloth layer, a lower base cloth layer and floating warps, wherein the upper base cloth layer is formed by interweaving warps and wefts; the lower base cloth layer is formed by interweaving warps and wefts; the upper-layer base cloth layer and the lower-layer base cloth layer are respectively formed by interweaving warp and weft yarns, the upper-layer base cloth layer can adopt a warp and weft one-up and one-down interweaving mode, and the lower-layer base cloth layer can adopt a warp and weft one-down and one-up interweaving mode; floating warp yarns can be woven from the upper-layer base cloth layer and the lower-layer base cloth layer at the same time; the utility model has the beneficial effects that the bottleneck that the size of the pattern is limited due to the size of the pattern cutting roller in the prior art is broken through, and the target of larger pattern is realized; the problem that floating beards are too short due to the fact that the patterns are close to one another in the patterns is solved, and the length of the floating beards can be flexibly adjusted according to the interval of the base cloth; the weaving efficiency is improved, the product is more stereoscopic and layered, the color is richer, the weaving is more convenient, the market competitiveness and the additional value of the product are improved, and the fabric has a wide market application prospect.

A gradient impedance-gradient multi-fiber hybrid broadband absorbing structure is provided, comprising a multi-fiber preform and a low-loss matrix. The low-loss matrix fills within the multi-fiber preform and covers it, with a covering thickness of <0.2 mm. The multi-fiber preform is formed by weaving together high-loss, medium-loss, and low-loss fibers. The multi-fiber preform includes an impedance matching layer formed by low-loss fiber weaving, an impedance transition layer formed by mixing low-loss and medium-loss fibers, and an absorption attenuation layer formed by mixing medium-loss and high-loss fibers. The impedance matching layer, impedance transition layer, and absorption attenuation layer are stacked sequentially to form a three-dimensional structure. This invention can effectively control its microwave electromagnetic characteristics, achieve a reasonable impedance gradient change, and significantly improve broadband absorption performance.

This invention discloses a fully automatic flexible feeding device for medical braided sheath mandrels, comprising a feeding robotic arm and a braiding machine body located to the left of the feeding robotic arm. The feeding robotic arm is equipped with mechanical claws for gripping the sheath mandrel. The braiding machine body is fixedly mounted with equidistant sliding guide rails, each with a sliding seat. A receiving block is fixedly mounted on the top of each sliding seat, and a circular block is rotatably connected to the top of the receiving block. A braiding conveyor seat is fixedly mounted on the braiding machine body. This invention employs multi-segment support for the sheath mandrel, combined with rotational and translational motion, to feed the sheath mandrel. This maintains the structural stability of the flexible sheath mandrel. Simultaneously, after feeding, the sheath mandrel is positioned within a through-hole, constraining and restricting it, ensuring feeding stability, facilitating braiding processing, and improving the braiding quality of the medical braided sheath mandrel.
