Question

A reed has 15 dents/cm, and the warp is drawn in two ends per dent. If the finished fabric is 1.4 m wide compared with 1.47 m wide in the reed, what is the finished fabric sett?

• A. 26
• B. 28
• C. 32
• D. 35

Hint:

Fabric sett is inversely proportional to fabric width. If the fabric shrinks in width, the sett increases. Remember: (Reed Sett Reed Width) = (Finished Sett Finished Width).

Answer 1

The Correct Option is C

1. Calculate the total number of ends in the reed: 
   Reed width = 1.47 m = 147 cm
   Dents/cm = 15
   Ends/dent = 2
   Total ends = 147 cm * 15 dents/cm * 2 ends/dent = 4410 ends
2. Calculate the finished fabric sett (ends/cm):
   Finished fabric width = 1.4 m = 140 cm
   Finished fabric sett = Total ends / Finished fabric width = 4410 ends / 140 cm = 31.5 ends/cm ≈ 32 ends/cm

Therefore, the finished fabric sett is approximately 32 ends/cm.
