raw material A: pure cotton 50S/1-combing compact siro spinning 60kg

Raw material B: white half light 70D/68F chinlon DTY 40kg

The processing technology comprises the following steps: the method comprises the following steps of firstly hanging corresponding raw materials on a silk frame, introducing yarns into an inductor through a yarn guide pipe, separating the raw materials A from the raw materials B through a yarn guide hook, directly enabling the raw materials A to enter an air nozzle 33 through a third roller 36, enabling the raw materials B to enter a first roller 34 to wind five circles, enabling the raw materials B to enter a third roller 36 to wind five circles, enabling the raw materials B to enter the air nozzle 33 after the raw materials A and the raw materials B enter the third roller 36 to wind five circles, enabling the two yarns to pass through the air nozzle 33 together and then be combined, enabling the two yarns to wind five circles through a second roller 35, and finally enabling the two yarns to enter a winding device 4 to produce brocade cotton doubled yarns.

Example 2:

raw material A: 6kg of white semi-gloss 140D spandex

Raw material B: white semi-light 150D/48F normal temperature cation DTY 4 strips 94kg

The processing technology comprises the following steps: the method comprises the following steps of firstly hanging corresponding raw materials on a yarn frame, introducing yarns into an inductor through a yarn guide pipe, introducing a raw material B into a third roller 36 through a yarn guide hook, winding the raw material B together with the raw material A for five circles, winding the raw material A for half circle at a first roller 34 through an additionally-arranged spandex support, entering the third roller 36, winding the raw material B together for five circles, entering an air nozzle 33, compounding two yarns after passing through the nozzle, winding for five circles at a second roller 35, and finally entering a winding device 4 to produce the positive-spun doubled yarn.

Example 3:

raw material A: 100kg of A0QM black 150D/48F terylene environment-friendly recycled yarn DTY 8

The processing technology comprises the following steps: firstly, hanging the corresponding raw material A on a creel, introducing the yarn into an inductor through a yarn guide pipe, introducing the raw material A into a third roller 36 through a yarn guide hook, winding for five circles, entering the third roller 36, winding for five circles, entering an air nozzle 33, compounding 8 yarns after passing through the air nozzle 33, winding for five circles on a second roller 35, and finally entering a winding device 4 to produce the dyed yarn doubled yarn. The advantage of the dyed yarn doubled yarn is that it meets the need for thick denier.

The air covered yarn machine can be used for producing high-D doubled yarns and can also be used for producing spandex composite yarns. Wherein, the spandex support is arranged between the third roller 36 and the first roller 34, and a spandex yarn tube 51 is arranged on the spandex support. The plurality of common yarns are drawn onto the second yarn guide 32 through the yarn introducing device 2, the yarns are wound onto the third roller 36 through the second yarn guide 32, meanwhile, the spandex on the spandex yarn bobbin 51 is drawn onto the third roller 36 through the first roller 34, and the spandex and the plurality of common yarns are converged at the third roller 36 and then enter the air nozzle 33 together for compounding, and finally, the yarns are wound into a bobbin through the second roller 35 and the winding device 4.

According to some embodiments of the present application, optionally, the first roller 34 is detachably provided on the roller frame 3. The size of the first roller 34 may be changed as appropriate depending on the process. Specifically, the first roller 34 is fixed on the godet frame through screws, and the first roller 34 can be quickly disassembled and assembled.

According to some embodiments of the present application, optionally, the first roller 34 is the same size as the third roller 36.

The diameter of the first roller 34 on the existing air packing machine is smaller than that of the third roller 36, the length of the first roller is shorter, the first roller is mainly used for assisting the spandex yarn bobbin 51 on a spandex support to unwind, and the main defects of the first roller are as follows: the original first roller 34 is short, and the thick-D spandex yarn bobbin 51 is long, so that spandex can run out of the effective working range of the roller during unwinding, and the conventional air packing machine cannot be applied to the thick-D spandex. In addition, because the existing control system can not control the rotating speed of the first roller 34, the diameters of the existing first roller 34 and the third roller 36 are not equal, the speed relation between the two rollers can not be calculated, and the tension between the first roller 34 and the third roller 36 can not be controlled. Therefore, in order to solve the above problem, on the one hand the handling system is improved and on the other hand the first roller 34 is provided with the same dimensions as the third roller 36. The tension of the yarn between the first roller 34 and the second roller 35 is controlled by the difference of the rotating speed of the first roller 34 and the third roller 36, so that the free control of the positive overfeed and the negative overfeed of the first roller 34 is realized.
