Question

If there are 72 dents per 2 inches in a reed and 2 ends/yarn are drawn from each dent, what will be ends/yarn per inch of the fabric?

• A. 36
• B. 72
• C. 18
• D. 12

Hint:

Formula: Ends per inch = (Dents per inch) × (Ends per dent).

Answer 1

The Correct Option is B

Step 1: Understanding reed and dents.
In weaving, a reed is a comb-like structure with vertical dents (spaces). Ends of warp yarns are passed through dents to control density.
Step 2: Calculate dents per inch.
It is given that there are 72 dents per 2 inches. Therefore, dents per inch = \(\frac{72}{2} = 36\).
Step 3: Ends per dent.
From the question, 2 ends/yarn are drawn from each dent. Therefore, number of ends per inch = 36 dents × 2 ends = 72 ends.
Step 4: Verification.
- If only 1 end was per dent, ends per inch would be 36.
- Since 2 ends are per dent, the count doubles to 72.
Step 5: Conclusion.
Hence, the fabric will have 72 ends per inch.
