The word ‘Selvedge’ is relevant to ‘Self-edge’ of the Denim Fabric. Selvedge is woven so the fabric’s ‘edge’ can be used for the creation of garments. When it comes to Jean construction if its outer edge is done with (Self-edge) Then it called as a ‘selvedge’ denim jeans. Selvedge Denim tends to have a tougher, thicker weave than non-selvedge Denim. This Densest feature gives the denim a sturdier hand. If we use older selvedge loom technology then it creates variations on the denim surface (due to mismatching in the weaving process) besides if we use denim woven on modern looms it will not show inconsistencies. These differences provide denim with a unique look and highly grateful. 

Origin

Selvedge denim is woven by doing old-fashioned denim-weaving techniques; most genuinely woven on old looms. See finished selvedge jeans. Selvedge looms were in vogue for denim weaving until the mid-to-late 1900s. US denim mills started to modernize their machinery to speed production as required for denim grew globally. For these mills, they were paid more and more focus on increasing output, the use of old selvedge looms are outrageous, making the looms outdated due to they are retarded and provides less consistent production. However, at this time, selvedge denim has turned into the more desirable design if compared to non-selvedge due to these two reasons: the shade of the denim weaving technique itself and the guarantee to quality from the mills producing selvedge denim. Japanese mills are the peak leaders in selvedge denim production, at present.

Salvage of Selvedge

The term selvedge is derived from “self-edge.” The border of the denim fabric has a clean finish since it will not unravel, the edge of the fabric is used as the clothes outseam. Therefore, looking at the inner of the outseam is an easy way to identify whether the pair is made of selvedge or other. There are the different pronunciation of the term: selvedge or selvage. Both are grammatically correct. The brand gives priority using the former in its product titles and descriptions, because of its direct relevance to the root word “edge.”

Finally

Selvedge denim and raw denim are not considered the same. Raw denim is the one never washed. Therefore, all denim – whether they are selvedge or non-selvedge – is raw when it comes out of the loom. Washed denim is not raw. There may be many questions concerning the variation between selvedge and non-selvedge denim. One is not foremost to the other in terms of quality and longevity. Moreover, the cotton and the dyeing processes used for selvedge are not necessarily distinct than those utilized for non-selvedge. But when it comes to comfort, non-selvedge may provide somewhat more flexibility and pliability in fabric. However, the selvedge is undoubtedly more desirable and attractive.
