Question

The material flow of the warp sheet through different zones in a sizing machine is \(\underline{\hspace{2cm}}\). 
A. Drying zone 
B. Size box zone 
C. Beaming zone 
D. Creel zone

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

Hint:

The sizing process follows a logical path: 1. Unwind the yarn (Creel). 2. Apply the size (Size Box). 3. Dry the yarn (Drying Zone). 4. Rewind onto the final beam (Beaming Zone).

Answer 1

The Correct Option is B

Step 1: Visualize the process of a sizing machine (slasher). The process starts with the yarn supply and ends with the final sized beam.

Step 2: Sequence the zones logically.
- D. Creel zone: The process begins here. The weaver's beams from warping are placed in a creel to feed the yarn as a continuous sheet into the machine.
- B. Size box zone: After leaving the creel, the sheet of yarn is immersed in the size paste in the size box to apply the sizing chemical.
- A. Drying zone: The wet, sized yarn then immediately moves into the drying zone (e.g., hot cylinders or a hot air chamber) to remove the moisture.
- C. Beaming zone (or Headstock): After drying, the yarn sheet is separated by lease rods and wound onto the final loom beam at the headstock.

Step 3: Match the sequence to the options. The logical sequence is D \(\rightarrow\) B \(\rightarrow\) A \(\rightarrow\) C. This corresponds to option (B).
