Questions and Answers

Which characteristic is used to determine the face of a fabric if the lustre is the same on both sides?

  • Selvedge
  • Crimp
  • Thread count
  • Clarity of design (correct)

How can warp and weft threads be identified if selvedges are present in the fabric sample?

  • By the size of the threads
  • By the crimp of the threads
  • By the thread count
  • By the threads parallel and perpendicular to the selvedges (correct)

What is the general relationship between the number of warp and weft threads in a fabric?

  • Weft threads are more dense than warp threads
  • Warp threads are more dense than weft threads (correct)
  • Warp and weft threads have the same density
  • Thread density cannot be used to identify warp and weft
