  • the feeding part comprises:
  • the spinning part comprises:
  • the twisting and winding part comprises:
  • the roving (10) forming the main material of the core yarn according to the invention is wound over a roving bobbin (11).
  • the filament yarn (20) which is the material that provides elasticity, strength, and rewinding capability by being fed into the main material during spinning operation, is found in wound state on the filament yarn bobbin (21).
  • the elastane yarn (30) which provides elasticity by being fed into the main material during spinning operation is also found in wound state over the elastane yarn reel (31).
  • Cord bobbins (11) and filament yarn bobbins (21) are attached in the feeding part at the relevant places of the creel section.
  • the elastane yarn reel (31) is attached to the drive cylinder (32).
  • the roving (10) fed from the roving bobbin (11) to the spinning part is spun and refined by passing among the rear (90), middle (80), and front spinning rollers (70) and the rear (91), middle (81), and front sleeves (71) positioned on top of each other at this section.
  • the elastane yarn (30) and/or the filament yarn (20) is fed between the front spinning roller (70) and the front sleeve (71) so that it is spun together with the roving (10).
  • the elastane yarn (30) and/or the filament yarn (20) are not fed at a constant speed. Therefore, different drafting values are applied on the elastane yarn (30) and/or the filament yarn (20).
  • the feeding speed values are changed in the elastane yarn (30) and/or filament yarn (20) depending on the demanded length.
  • an elastane yarn (30) data input screen (40), an elastane yarn (30) drive motor (50), and an elastane yarn (30) inverter (60) are added to the spinning mechanism.
  • a filament yarn (20) data input screen (40), a filament yarn (20) drive motor (50), and a filament yarn (20) inverter (60) are added to the spinning mechanism.
  • the data input screen (40) is the screen where the designed yarn length and the speed values related to this length are entered.
  • the values taken from here are then transmitted to the drive motor (50) by means of the inverter (60) and the movement of the drive cylinders (22, 32) are changed as desired.
  • the inverter (60) transmits the command it takes from the data input screen (40) to the drive motor (50) in order to change the elastane yarn (30) and filament yarn (20) feeding speed.
  • the drive motor (50) changes the speed of the elastane yarn and filament yarn drive cylinders (32, 22) according to the command it takes from the inverter (60). In this way, the elastane yarn (30) and/or filament yarn (20) in different drafting values are fed to the core of the spun roving (10).
  • a servo motor is used as the drive motor (50).
  • Final core yarn is obtained by means of applying twisting and winding operations on the roving (10), the core of which is fed by elastane yarn (30) and/or filament yarn (20).
  • the obtained yarn is wound on cops (100).
  • Cops (100) are bobbins on which spun yarn is wound. While the spun yarn is wound around the cops (100), it is passed through a guiding eye (101) which guides said yarn.
  • This added servo motor (50) allows increasing or decreasing the instantaneous feeding amounts of the elastane and filament yarns via rotation of the drive cylinders (22, 32) at different speeds. Since the speeds of the front spinning roller (70) and the front sleeve (71) where the elastane yarn (30) and the filament yarn (20) are fed, do not change, it is made possible to feed the elastane and filament yarns (30, 20) at different drafting values.

  • fed elastane and filament yarn (30, 20) can be provided to the yarn core with different spinning variations.
  • the elastane and filament yarn (20, 30) are fed to the system through a single drafting value with the first spinning of the production.
  • these spinning values can be adjusted within the desired length interval.
  • the elastane yarn drive cylinder (32) and the filament yarn drive cylinder (22) rotate at a constant speed.
  • the data input screen (40), inverter (60), and servo motor (50) integrated to the yarn spinning mechanism thanks to the invention the elastane yarn drive cylinder (32) and the filament yarn drive cylinder (22) can rotate at different speeds. In this way, production of core yarn with different drafting values can be achieved by unwinding and feeding elastane and/or filament yarns (30, 20) at different tensions.
  • Data is entered into data input screen (40) for rotation at different speeds and times and these data is transferred to the servo motor (50) by means of the inverter (60) and thus the speed of the drive cylinders (22, 32) can be changed.
  • the speed of the drive cylinders (22, 32) can be changed.
  • feeding of the fed elastane and/or filament yarn (20, 30) at different tensions is ensured.
  • core yarn comprising elastane and/or filament yarn (20, 30) different drafting values are produced and 3-d fabric production is ensured by knitting or weaving of these yarns.
