For example, the method for weaving by adopting the weaving structure of the variable-diameter multi-branch tissue fabric comprises the following steps:

(1) the let-off servo motor drives the synchronous belt gear set to rotate so as to drive the independent warp beam to rotate, warp yarns are discharged from the independent warp beam and bypass the yarn passing roller to form an s-shaped route, the pressure stress of the warp yarn tension on the yarn passing roller is reflected by the tension sensor to generate the yarn tension, the tension data is fed back to the control system, the let-off speed is continuously adjusted according to the tension, when the tension is too small, the forward let-off speed of the let-off servo motor is reduced or the let-off servo motor rotates reversely, when the tension is too large, the forward let-off speed of the servo motor is increased, and therefore the stability of the warp yarn tension in the weaving process is maintained;

(2) the warp yarns pass through the tooth reeds of the through-line carding reed, and are orderly carded out in the wiring process, so that the yarns in the wiring process are prevented from being wound and crossed; the warp yarn passing through the through-yarn carding reed keeps the weaving yarn and the reed door at a horizontal height through a yarn pressing roller;

(3) after the warp yarns pass through the broken warp detection device, each yarn passes through a heddle eye corresponding to a heddle lifting device, namely, each heddle controls each yarn, the upper end of each heddle is connected with a jacquard faucet, the lower end of each heddle is connected with a return spring, the jacquard faucet controls the heave change of the warp yarns by lifting the heddles to form an opening, and the shuttle feeds weft yarns into the opening so as to form different fabric tissues;

(4) weaving the equal-diameter area of the main pipe: all warp yarns are woven into a region of the main tube, which can be woven into a tube using one or more shuttles: one shuttle is woven to carry out conventional tube-forming tissue shuttle walking, and the other shuttles do not carry out weaving action; the shuttle changing and beating-up are carried out at each warp direction position by utilizing the stopping and warping for the weaving beating-up of a plurality of shuttles, so that a plurality of groups of wefts of the multi-bifurcated pipe participate in the weaving, and the phenomenon of outward floating of the weft is avoided;

(5) weaving the main pipe reducing area: the warp yarn is positioned in different reed dense areas by controlling the lifting of a V-shaped profiled reed structure in the tube-forming weaving process, so that the warp yarn density and the tube diameter of a tube tissue are changed by the cloth fell in different warp dense areas, and the number of circulating wefts woven in each area, the diameter-changing range and the lifting times of the diameter-changing area are input in a human-computer interface; for example, 100 picks are arranged in a diameter-variable area, the diameter is changed from 20mm to 15mm in the weaving process, a reed in the diameter-variable area is lifted 3 times, after the machine is controlled by internal program calculation, the machine can independently lift 3 times from a reed dense area with a weaving tubular diameter of 20mm after entering the diameter-variable area, the reed ascends once every 33 picks on average, and the profiled reed is finally stopped at the reed area with the weaving diameter of 15mm to weave the artificial blood vessel;

(6) and (3) knitting a crotch area: the bifurcation area is a transition area of a main pipe divided into a plurality of thin pipes, and is described by taking a trident pipe as an example, the weaving of the bifurcation area divides warps into three parts from left to right, then three shuttles are utilized to sequentially correspond to the warps of each area, one shuttle corresponds to the weaving of one thin pipe, and the shuttles corresponding to the thin pipes are numbered as shuttle No. 1, shuttle No. 2 and shuttle No. 3 from left to right, in order to prevent the wefts from being intertwined in the shuttle walking process, the shuttle walking sequence should be shuttle No. 1, shuttle No. 2 and shuttle No. 3, shuttle No. 2 and shuttle No. 1 are sequentially circulated;

(7) weaving the thin tube area: after entering a tubule area, the shuttle walking sequence is still the shuttle walking circulation of the shuttle walking sequences of the shuttle walking 1, the shuttle walking 2 and the shuttle walking 3, the shuttle walking 2 and the shuttle walking 1, the later diameter change is that the weaving port warp density is changed by lifting the V-shaped profiled reed, meanwhile, the shuttle walking every time needs to be stopped and warped at the same position, and the shuttle is lifted and lowered to change the shuttle, the shuttle can realize the lifting movement, so that a plurality of wood shuttles weave the same cloth surface together, and the weft types and colors for weaving the same cloth surface are changed by lifting different wood shuttles in the same row to the weaving port to beat up, thereby realizing the weft changing action of the wood shuttle loom;

(8) in the weaving process, because the profile reed is in different density areas at different heights, the cloth fell can lead the warp density and the width of the woven belt to change once the cloth fell deviates, the cloth fell position is stabilized by the front end clamping mechanism, the cloth fell is prevented from deviating up and down due to the up-and-down movement in the warp opening process, the cloth fell is separated from the cloth fell after the warp and weft weaving is formed, after the weaving is finished, the coiling mechanism is used for coiling the cloth, in addition, the coiling plays a role in stopping and warping, under the condition of multiple weft threads, multiple weft threads can be beaten at the same warp position, the coiling and warp feeding stop work needs to be controlled, and the warp is continuously pulled to advance after the shuttle is changed and moved for multiple times at the position.

The invention has the beneficial effects that:

according to the invention, the back warp creel actively sends warp, yarns are orderly combed by the threading combing reed, the yarns keep the weaving yarns and the reed door at the horizontal height through the yarn pressing roller, then the yarns pass through the broken warp detection device, each yarn passes through the heddle eye corresponding to the heald lifting device, the jacquard faucet controls the rise and fall change of the warp yarns to form an opening through lifting the heddles, the shuttle sends the weft yarns into the opening, the shuttle can realize lifting motion, the weft yarn type and color for weaving the same cloth cover are changed, and the weft changing action of the wooden shuttle loom is realized; the V-shaped profiled reed can realize lifting movement and is used for changing the relative position between the profiled reed and a weaving opening, so that warp yarns are in different reed density areas, the warp density and the cloth surface width of the same cloth surface can be changed, and the weaving of various wefts and widths of the same cloth surface can be changed according to requirements by matching with the profiled reed.
