Jacquard
A system of weaving which utilizes a highly versatile pattern mechanism to permit the production of large, intricate designs. The weave pattern is achieved by a series of punched cards. Each card perforation controls the action of one warp thread for the passage of one pick. The machine may carry a large number of cards, depending upon the design, because there is a separate card for each pick in the pattern.
Jacquard weaving is used for tapestry, damask, brocatelle, figured necktie and dress fabrics, and some floor coverings. A similar device is used for the production of figured patterns on some knit goods.
Jaspé

Jean
Comes from the French word “Genes” used to describe the pants sailors from Genoa once wore. While the historical definition implied that all jeans were made of denim, jeans today usually refer to a garment that has 5 pockets (two in the front, two in the back and a small change pocket on the front right pocket) and this style can be made using any kinds of fabrics be it corduroy, twills, or bull denim.
Jersey

A tricot fabric made with a simple stitch, characterized by excellent drape and wrinkle recovery properties.
Jet
A device used to bulk yarns by introducing curls, coils, and loops which are formed by the action of a high velocity stream, usually of air or steam.
