Fabric Analysis: Determining Face of the Fabric

Play an AI-generated podcast conversation about this lesson

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
