A basic stitch used in weft knitting in which the knitting machines require two sets of needles operating at right angles to each other. Rib knits have a very high degree of elasticity in the crosswise direction. A 1 x 1 rib has one rib up and one down. A 2 x 1 rib has two ribs up and one down. This knitted fabric is used for complete garments and for such specialized uses as sleeve bands, neck bands, sweater waistbands, and special types of trims for use with other knit or woven fabrics. Lightweight sweaters in rib knits provide a close, body-hugging fit.
