From Wikipedia: Corduroy is a textile with a distinctive texture—a raised “cord” or wale. Modern corduroy is most commonly composed of tufted cords, sometimes exhibiting a channel (bare to the base fabric) between the tufts. Both velvet and corduroy derive from fustian fabric. The fabric looks as if it is made from multiple cords laid parallel to each other and then stitched together. The word corduroy is from cord and duroy, a coarse woollen cloth made in England in the 18th century.
Corduroy is made by weaving extra sets of fibre into the base fabric to form vertical ridges called wales. The wales are built so that clear lines can be seen when they are cut into pile.Graphite-coloured standard corduroy to the left showing approx 7 wales-per-inch, with brown needlecord at 16 wales to the inch
The primary types of corduroy are:
- Standard wale: 11 wales/inch, and available in many colors
- Pincord/pinwale/needlecord: Pincord is the finest cord around with a count at the upper end of the spectrum (above 16)
- Pigment dyed/printed corduroy: The process of colouring or printing corduroy with pigment dyes. The dye is applied to the surface of the fabric, then the garment is cut and sewn. When washed during the final phase of the manufacturing process, the pigment dye washes out in an irregular way, creating a vintage look. The colour of each garment becomes softer with each washing, and there is a subtle colour variation from one to the next. No two are alike.
