Q: What are the main types of selvedges and how they are formed?

A: The main types of selvedges are tuck-in selvedge, fused selvedge and leno selvedge. Tuck-in selvedge is formed by tucking-in protruding portions of each pick into the next warp shed, alongside the new pick, and beating them up together with it. Fused selvedge is the thermoplastic warp and weft that are welded together by heat and pressure. Leno selvedge is formed by one or more pairs of strong, highly tensioned ends that interface with the weft on the leno principle. Warp threads are crossed and interwoven into the edges of the fabric.
