Selvedge denim is a type of denim fabric that is characterized by a clean edge on both sides of the fabric, which prevents it from unraveling and fraying. The term "selvedge" is a corruption of "self-edge," and it has been in use since the 16th century. Selvedge denim is produced using a unique weaving process that differs from traditional denim fabric, and it is often considered higher quality than non-selvedge denim because of its durability and uniqueness. The primary difference between selvedge and non-selvedge denim lies in the type of loom used to weave the fabric. Selvedge denim is made on a shuttle loom, which creates a narrower fabric with a tighter weave, resulting in a more durable and heavy-weight denim with a pronounced ridged edge. The quality of selvedge denim is often considered higher than non-selvedge denim because of its durability and uniqueness. Selvedge denim is often viewed as the more premium and long-lasting option, while non-selvedge denim offers a more affordable alternative for those who still appreciate denim as a wardrobe staple.
