Example 1
The production method of the air-jet vortex spun-bonded adhesive short fiber covered spandex elastic slub yarn with the specification of R30S +40D spandex filaments comprises the following specific spinning processing steps:
preferably, the viscose staple fiber sliver with the quantitative of 18g/5m is fed from a horn mouth of an air jet vortex spinning machine on a Japanese village MVS870 type air jet vortex spinning machine, passes through a fourth roller, a fourth leather roller matched with the fourth roller, a third leather roller matched with the third roller, a middle roller matched with the middle roller, a front roller and a front leather roller matched with the front roller in sequence, is drafted, and then enters an air jet vortex spinning chamber.
Meanwhile, spandex filaments with a linear density of 40D and a maximum elastic elongation of 60% are preferably placed on a core filament creel of an air-jet vortex spinning core spun yarn device as a core filament raw material. On the air-jet vortex spinning core-spun yarn device, feeding spandex filaments from a yarn guide element, sequentially passing through a core yarn tension roller, a core yarn tension controller and a core yarn output roller, feeding the spandex filaments to a front roller nip of an air-jet vortex spinning machine, combining the spandex filaments with drafted viscose staple fiber strands, and feeding the combined spandex filaments and the drafted viscose staple fiber strands into an air-jet vortex spinning chamber; and outputting the finished yarn from the air-jet vortex spinning chamber, clearing the yarn defects through the yarn clearing detection of an electronic yarn clearer, and winding the yarn into cheese after passing through a yarn guide tension roller. According to the spinning requirement that the base yarn number of the elastic bunchy yarn is 30S, main technological parameters of the air-jet vortex spinning machine are set as follows: the spinning speed is 350m/min, the air pressure of a nozzle is 0.51Mpa, and the feeding ratio of the short fiber strands is 0.98; the speed of the core wire output roller is kept constant with that of the front roller.
In the forming process of bamboo joints, according to the maximum elastic elongation of spandex filaments of 60%, the range of the draft multiple of a manually input core filament tension roller in a motor variable speed controller is 0.98-1.60, and the operating time range at each instantaneous operating speed is 10-100 ms. Under the range of the drafting multiple, the range of the drafting tension change of the core yarn for ensuring the stable feeding of the core yarn is set to be 10 cN-25 cN. The motor variable speed controller randomly outputs corresponding core wire tension roller rotating speed values and time values running at the rotating speed to the servo motor according to the drafting multiple range of the core wire, so that the servo motor drives the core wire tension roller to rotate at variable speed through the synchronous toothed belt.
At a certain time of spinning processing, when a motor variable speed controller randomly selects spandex filaments to run for 12ms under the condition that a core filament tension roller keeps a 1.6 drafting multiple state, and bamboo joints are obtained; then, the draft multiple is recovered to 0.98, and the operation is carried out for 15ms under the draft multiple, so that the bamboo joint distance is obtained;
then, the motor variable speed controller outputs the next variable speed value, selects spandex silk to run for 15ms under the condition that the core silk tension roller keeps the drafting multiple of 1.3, and then the drafting multiple is restored to 0.98, and runs for 18ms under the drafting multiple. Therefore, the range of the drafting multiple of the core yarn tension roller of the motor variable speed controller is set according to the maximum elastic elongation of the core yarn, and a variable speed value and the running time at the speed are randomly output to the servo motor. The core yarn is wrapped by the outer wrapping fiber under different drafting times to form yarn. After the yarns are formed, the core wires retract, so that slubs are formed, and the spinning and processing of the air-jet vortex spinning spandex core-spun elastic slub yarns are realized.
In the whole processing process, within the variation range of the drawing tension of 10 cN-25 cN, each speed value output by the motor variable speed controller corresponds to a specific drawing tension value of the core yarn. The core wire tension controller monitors the core wire drafting tension value in real time and keeps constant at a certain speed value, if the core wire drafting tension value fluctuates, the core wire tension controller feeds the fluctuation condition back to the motor variable speed controller, and the motor variable speed controller finely adjusts the output variable speed value, so that the core wire drafting tension value is guaranteed to be constant at a certain speed.

According to the spinning requirement that the base yarn number of the elastic slub yarn is T30S, main technological parameters of the air jet vortex spinning machine are set as follows: the spinning speed is 350m/min, the air pressure of a nozzle is 0.53Mpa, and the feeding ratio of the short fiber strands is 0.98. The speed of the core wire output roller is kept constant with that of the front roller.
In the process of forming slubs, because the polyester slub filaments have slubs, in order to control the return of the slubs on the slub filaments, the constant value of the drafting multiple of the core yarn tension roller is manually input to be 1.02 in the motor variable speed controller. The polyester slub filament yarns are combined with polyester fiber strands at a nip of a front roller under the constant drafting multiple state and enter an air-jet vortex spinning chamber together, and polyester staple fibers are wrapped outside slubs of the polyester slub filament yarns to form the air-jet vortex spinning core-spun slub yarns.
In the whole processing process, the core yarn tension controller monitors the core yarn drafting tension in real time to keep 15cN constant, and when the core yarn drafting tension fluctuates, the core yarn tension controller sends a fluctuation value to the motor variable speed controller, so that the motor variable speed controller performs variable speed adjustment to recover the core yarn drafting tension to 15 cN.
