Knit Fabric: A structure produced by interlooping one or more ends of yarn or comparable material.

Knitting: A method of constructing fabric by interlocking series of loops of one or more yarns. The two major classes of knitting are warp knitting and weft knitting, as follows:

1. Warp Knitting: A type of knitting in which the yarns generally run lengthwise in the fabric. The yarns are prepared as warp on beams with one or more for each needle. Examples of this type of knitting are tricot, milanese, and raschel knitting.

Milanese Knitting: A type of run-resistant warp knitting with a diagonal rib effect using several sets of yarns.

Raschel Knitting: A versatile type of warp knitting made in plain and jacquard patterns; the latter can be made with intricate eyelet and lacy patterns and is often used for underwear fabrics. Raschel fabrics are coarser than other warp knit fabrics, but a wide range of fabrics can be made. Raschel knitting machines have one or two sets of latch needles and up to thirty sets of guides.

Tricot Knitting: A run-resistant type of warp knitting in which either single or double sets of yarn are circular and flat knitting.

2. Weft Knitting: A common type of knitting, in which done continuous thread runs crosswise in the fabric making all of the loops in one course. Weft knitting types are circular and flat knitting:

Circular Knitting: The fabric is produced on the knitting machine in the form of a tube, the threads running continuously around the fabric.

Flat Knitting: The fabric is produced on the knitting machine in flat form, the threads alternating back and forth across the fabric. The fabric can be given shape in the knitting process by increasing or decreasing loops. Full-fashioned garments are made on a flat knitting machine.

Aesthetics: In textiles, properties perceived by touch and sight, such as hand, color, luster, drape and texture of fabrics or garments.
