Woven fabrics are composed of two sets of yarns, interlaced at right angles. One set of yarns, the warp, runs along the length of the fabric. The other set of yarns, the fill or weft, is perpendicular to the warp. Woven fabrics are held together by weaving the warp and the fill yarns over and under each other, creating the appearance of a basket weave. Examples are Twill, Chiffon, Denim and Poplin.
Knit fabrics, on the other hand, a continuous loop of yarn is used to construct the material, giving it a braided appearance.
Knit fabrics contain loops of fibers that allow the material to stretch in one or both directions, while woven fabrics only stretch on the bias.
Non-woven fabric is made of fibers that are deposited in a relatively stochastic (random) manner on a surface and then bound together in some manner including (but not limited to) partial melting (of the fiber or a matrix in which the fiber is embedded), felting (which tangles the fibers together) etc.
Non-woven textiles are usually homogenous and isotropic having no preferred direction of ripping or unraveling.
Examples of non-woven's are:
Geotextiles used as reinforcement and covering
Felt used as insulation, filters, apparel
