What fabric construction results in diagonal ridges?

The fabric construction that results in diagonal ridges is the twill weave. This technique involves weaving threads in a manner that creates a pattern of diagonal lines on the surface of the fabric. The structure is formed by passing the weft thread over and under two or more warp threads in a repeated sequence, which produces a distinctive diagonal rib or ridge pattern.

Twill fabrics are known for their durability and strength, making them a popular choice for various apparel items, including denim, which prominently features a twill weave. This diagonal texture not only adds visual interest to the fabric but also enhances its performance by allowing it to drape well and resist creasing, which is particularly beneficial in the fashion and accessories market.

Other fabric constructions like knitted fabric, plain weave, and jacquard do not result in diagonal ridges. Knitted fabric is typically stretchy and has loops of yarn, plain weave is characterized by a simple crisscross pattern that does not produce diagonal lines, and jacquard weave is known for its complex patterns but does not inherently create diagonal ridges.
