Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a high-elastic bread yarn preparation method, as shown in figures 1 and 2, including the following steps:
yarn end of S1: after an elastic yarn barrel is arranged in a spindle disc of a yarn storage disc 1, an elastic yarn 2 penetrates through a spindle core and a yarn guide pipe, so that yarn leading operation of the yarn storage disc 1 is completed, then the elastic yarn 2 is sequentially led through an upper drawing roller 3, a shaping hot box 4 and a lower drawing roller 5, finally, the thread end of the elastic yarn 2 is led into a bobbin 7 arranged on a winding roller 6, and the elastic yarn 2 is wound on the bobbin 7 for five circles and then put down a bobbin frame to complete yarn threading;
s2, debugging the two-for-one twister: setting the speed of a spindle at 4000rpm, setting the twist to be 0-100 twist, setting the proportion of rollers to be 65-85%, setting the proportion of winding to be 68-87%, setting the temperature of a shaping hot box to be 160-200 ℃, and setting the rotating speed of an upper drawing roller to be 60-85 m/min;
and S3 startup operation: after the parameters of the two-for-one twister are set, the two-for-one twister is operated;
and (3) removing the bobbin from the S4 yarn: after the two-for-one twister is operated, the physical properties of the stretch yarn 2 are changed, so that the yarn wound on the bobbin 7 meets the high-elastic surface covered yarn 8 of the specification, and finally the high-elastic surface covered yarn 8 is removed from the bobbin 7.
The utility model relates to a high elastic bread yarn manufacturing method, which matches the temperature of a setting hot box 4 with the speed of an upper drafting roller 3 and a lower drafting roller 5 by adjusting the whole technological parameters, thereby achieving the purpose of enabling an elastic yarn 2 to be in a loose state; the elastic yarn 2 is physically changed in the hot box through the instant high-temperature shaping of the shaping hot box 4, so that the unstable state of the macromolecular chains in the elastic yarn 2 is changed into the stable state of ordered arrangement. The original length of the stretch yarn 2 before entering the hot box is 1 meter, the stretch can reach the length of 1.3 meters after elastic setting, and the physical property of the original stretch yarn 2 can reach the requirement of polyester (nylon-like) high-elastic surface covering yarn 8 through the process.
The spindle back pressure of a spindle disk on the two-for-one twister is adjusted to be 1.5kgf/m ^2, the spindle back pressure of the spindle disk is adjusted to be 1.5kgf/m ^2 from the conventional 2.5kgf/m ^2, so that the appearance of the stretch yarn 2 after two-for-one twisting is soft to meet the specification of the covering yarn and the requirement of yarn dyeing in the subsequent process.
The overfeed rate between the upper drafting roller 3 and the lower drafting roller 5 is 1%. The filament transferor 9 on the two-for-one twister moves once every 10 mm. The spindle position tension of the spindle disk on the two-for-one twister is adjusted to 0.2 CN/dtex. The unwinding angle of the twisting balloon on the two-for-one twister is 360 degrees. The process parameters are adjusted to make the manufactured yarn more accord with the process requirements of the terylene (nylon-like) high-elastic surface covering yarn 8.
The upper drafting roller 3 and the lower drafting roller 5 are both belt rollers, and the pressure of the upper drafting roller 3 and the lower drafting roller 5 on the elastic yarn 2 is 0.7 to 1kgf/m ^ 2. Because the overfeed rate between the upper drafting roller 3 and the lower drafting roller 5 is 1 percent in the process, the elastic yarn 2 cannot be stably wrapped by using the conventional overfeed roller, the elastic yarn 2 can be stably conveyed while the process requirements can be met by adopting the belt type roller, and the pressure of the upper drafting roller 3 and the lower drafting roller 5 on the elastic yarn 2 is 0.7 to 1kgf/m 2, so that the elastic yarn 2 cannot be damaged while the elastic yarn 2 is stably conveyed.

The upper driven belt assembly 32 further comprises an upper spring member 33 capable of increasing the pressure of the upper belt 321 on the upper driving roller 31, and two ends of the upper spring member 33 are respectively fixed on the frame of the two-for-one twister and an upper crank 322. The pressure of the upper belt 321 against the elastic yarn 2 is 0.7 to 1kgf/m 2.
The lower draft roller 5 comprises a lower driving roller 51 and a lower driven belt assembly 52 which can be pressed against or away from the lower driving roller 51, and the elastic yarn 2 in the S1 is led through between the lower driving roller 51 and the lower driven belt assembly 52. The lower driven belt assembly 52 comprises a lower belt 521 and a lower curved rod 522, one end of which is hinged with the frame of the two-for-one twister, the other end of the lower curved rod 522 is rotatably provided with two lower belt rollers 523, and the two lower belt rollers 523 are arranged in the lower belt 521 in a matching way.
The lower driven belt assembly 52 further comprises a lower spring member 53 capable of increasing the pressure of the lower belt 521 on the lower driving roller 51, and two ends of the lower spring member 53 are respectively fixed on the frame of the two-for-one twister and a lower crank 522. The pressure of the elastic yarn 2 of the lower belt 521 is 0.7 to 1kgf/m ^ 2.
