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: Reed and Dent Basics.
In weaving, a reed is a comb-like tool with vertical dents (spaces). Warp yarns pass through these dents to manage fabric density.
Step 2: Calculate Dents Per Inch (DPI).
The problem states 72 dents are present in 2 inches. Thus, DPI = \(\frac{72}{2} = 36\).
Step 3: Ends Per Dent Calculation.
Each dent holds 2 yarn ends, as per the question. Therefore, ends per inch = 36 dents × 2 ends = 72 ends.
Step 4: Verification.
- If each dent held only 1 end, the result would be 36 ends per inch.
- With 2 ends per dent, the count increases to 72.
Step 5: Conclusion.
The fabric will therefore have 72 ends per inch.
