Question

In the draw texturising machine, the passage of yarn is:
A. primary heater
B. secondary heater
C. winding unit
D. creel
E. friction unit Choose the correct answer from the options given below:

• A. A, E, D, C, B
• B. D, A, E, B, C
• C. E, D, B, A, C
• D. B, E, A, D, C

Hint:

The heater is always "Primary" then "Secondary." Winding is always the final step. This logic often eliminates most incorrect options immediately.

Answer 1

The Correct Option is B

Concept: Draw texturizing (False Twist Texturizing) is a process used to give bulk and stretch to synthetic filament yarns.

Step 1: Determining the Flow of Material.

• D (Creel): The process starts at the creel where the supply packages (POY) are held.
• A (Primary Heater): The yarn is heated to a temperature above its $T_g$ to make it pliable for twisting.
• E (Friction Unit): The rotating discs insert a high level of false twist.
• B (Secondary Heater): The yarn is heated again while in a relaxed state to set the crimp and stabilize the bulk.
• C (Winding Unit): Finally, the texturized yarn is wound onto the take-up package.
