Knitwear (fr. Tricotage - knitted products) is a textile material (knitted fabric) or a finished product from a knitted fabric, as well as a one-piece knitted product, the structure of which is interconnected loops, in contrast to the fabric, which is formed as a result of the mutual interweaving of two systems of threads ( warp and weft), located in two mutually perpendicular directions, so the use of the phrase "knitted fabric" is incorrect. The knitted fabric is characterized by extensibility, elasticity and softness. In the production of knitted fabrics, synthetic, cotton, woolen and silk fibers are used in their pure form or in various combinations, including with the addition of elastane. The first knitwear found during archaeological excavations date back to the 3rd-1st centuries. BC e.
