In the present embodiment, the number of shuttles 2 is eight, and they are arranged on the cap 1 side by side and uniformly in sequence. The bobbin 2 includes a first bobbin 21 and a second bobbin 22. The first shuttle 21 is used for threading low-melting-point fiber yarns, and the second shuttle 22 is used for threading elastic fiber yarns. In other embodiments, there is no limitation on the number of shuttles 2 and no limitation on the type of yarn being threaded.
The shuttle device 3 comprises a cylinder block 31, a plurality of power cylinders 32, a return spring hanger 33, a plurality of return springs 34 and a solenoid valve 35. In the present embodiment, there are also eight return springs 34 provided corresponding to the respective shuttles 2.

The return spring hanger 33 is fixed to the cylinder block 31, and one end of the return spring 34 is fixed to the return spring hanger 33, and the other end is fixed to the shuttle 2. The power cylinder 32 and the return spring 34 cooperate to change the operating position of the shuttle 2.
The solenoid valve 35 is fixed to the cylinder block 31, and the control device changes the operating state of the power cylinder 32 through the solenoid valve 35.
Referring to fig. 3, the shuttle 2 includes a main body 23, a payout end 24, and an adjustment end 25.

When knitting starts, the knitting is performed according to the knitting method of knitting the conventional fabric, the control device controls the power cylinder 32 to push out, and the push rod of the power cylinder 32 is pushed onto the corresponding shuttle body 2, so that the adjusting end 25 of the shuttle body 2 is forced upwards, and the wire releasing end 24 of the shuttle body 2 is positioned downwards in the knitting area of the knitting device. The cap cover 1 is also provided with a shuttle plate, and the paying-off end 24 of the shuttle body 2 is reliably arranged on the shuttle plate.
When the knitting proceeds to a position where the skip is required, the working position of the first bobbin 21 through which the low melting point filament is threaded needs to be adjusted. The control device controls the electromagnetic valve 35 to work, so that the power cylinder 32 corresponding to the first shuttle body 21 changes state under the action of the electromagnetic valve 35, the push rod is retracted, the adjusting end 25 of the first shuttle body 21 moves downwards under the action of the reset spring 34, the paying-off end 24 of the first shuttle body 21 is lifted upwards, the paying-off end 24 leaves the knitting area of the knitting device, the low-melting-point fiber yarn is not knitted in temporarily, and meanwhile, the limiting cylinder limits the lifting shuttle height of the first shuttle body 21.
Referring to fig. 1 and 2, in the present embodiment, the number of limiting cylinders is two, and the limiting cylinders are disposed between the power cylinder 32 and the cap 1, so as to limit the lowest movement position of the adjusting end 25 of the first shuttle 21, that is, limit the highest movement position of the payout end 24 of the first shuttle 21, so that the position of the payout end 24 is not tilted too high when the first shuttle 21 jumps, thereby improving the precision of the jump weaving. If the payout end 24 of the first bobbin 21 is tilted too high during the skip, the fall time of the payout end 24 is increased, and the longer the fall time is, the more difficult the accuracy with which the low-melting-point filaments are re-woven back into the fabric is to be controlled.
When the part to be woven is completed, the control device again actuates the electromagnetic valve 35, so that the power cylinder 32 corresponding to the first shuttle body 21 changes state under the action of the electromagnetic valve 35, the push rod pushes out, the paying-off end 24 of the first shuttle body 21 falls back into the weaving area of the weaving device again, and the weaving device again weaves the low-melting-point fiber yarns. Due to the effect of the limiting cylinder, the wire releasing end 24 of the first shuttle body 21 just leaves the knitting area when the shuttle is lifted, so that when the first shuttle body 21 falls back, the return stroke is short, the falling time is greatly reduced, and the knitting precision is improved.
Referring to fig. 4 and 5, in another embodiment, a cylinder block 31 is fixed above the shuttle 2, and a return spring hanger 33 is fixed to the top of the cylinder block 31 such that the adjustment end 25 is subjected to an upward elastic force.
When knitting common fabric, the control device controls the push rod of the power cylinder 32 to be in the cylinder, the adjusting end 25 of the shuttle body 2 is lifted upwards under the action of the return spring 34, and the wire releasing end 24 of the shuttle body 2 is positioned downwards in the knitting area of the knitting device. The cap cover 1 is also provided with a shuttle plate, and the paying-off end 24 of the shuttle body 2 is reliably arranged on the shuttle plate.
When the jump is required, the working position of the first shuttle body 21 through which the low melting point fiber is threaded needs to be adjusted. The control device controls the electromagnetic valve 35 to work, so that the power cylinder 32 corresponding to the first shuttle body 21 changes state under the action of the electromagnetic valve 35, the push rod pushes out, the adjusting end 25 of the first shuttle body 21 moves downwards under the action of the power cylinder 32, the paying-off end 24 of the first shuttle body 21 is lifted upwards, the paying-off end 24 leaves the knitting area of the knitting device, and the low-melting-point fiber yarn is not temporarily knitted in, so that the attribute of the local fabric is changed.
In this embodiment, the push rods of the power cylinder 32 and the limit cylinder are respectively provided with a cylinder top sleeve, so that the push rods of the cylinders and the shuttle body 2 are protected to a certain extent, and abrasion is reduced.

Step one: the method comprises the steps of respectively penetrating different types of yarns on different shuttle bodies, controlling the operation of a braiding device by a control device, normally braiding according to a traditional braiding process, and braiding all the different types of yarns together;
Step two: when the local performance of the fabric is required to be changed during knitting, the control device controls the shuttle-jumping device to work, so that the designated shuttle body generates a shuttle-jumping action to bring the designated yarn out of a knitting area of the knitting device, and meanwhile, the control device controls the limiting device to work, so that the shuttle-jumping height of the designated shuttle body is limited, the yarn on the designated shuttle body only just leaves the knitting area, and the knitting device carries out knitting forming on the rest yarn;
step three: when the local performance fabric knitting of the fabric is required to be finished, the control system controls the shuttle-jumping device and the limiting device to work again, so that the separated designated shuttle body falls back, and the knitting device is used for knitting all types of yarns into the fabric again, so that the accurate shuttle-jumping knitting of the yarns of multiple types is finished.
The yarn comprises low-melting-point fiber yarns and elastic fiber yarns which are respectively arranged on different shuttles in a penetrating way, and when the shuttle-tripping device works, the designated shuttles leave the knitting area. In this embodiment, the shuttle moves away from the woven region carrying all of the low melt filaments or all of the elastic filaments. In other embodiments, the shuttle may also take out a portion of the low melt filaments or a portion of the elastic filaments away from the woven region.
