There are many types of rib weaves, and the numbers 1+1, 1+2, 2+2, etc. are usually used to represent the combination of the front and back coils in a complete weave. Figure 1 shows the structure of 1+1 rib weave, which is composed of a front side coil wale and a back side coil wale alternately arranged. If a front side coil wale and two back side coil wales are arranged alternately, a 1+2 rib structure is formed, and so on.
There are many composite weaves derived from rib weaves, mainly rib air layer weaves and dotted weaves. The ribbed air layer structure is composed of ribbed and flat stitched weaves. This kind of organization has small lateral extensibility, good dimensional stability, and has the advantages of being thick and stiff. The dot pattern structure is composed of incomplete rib structure and incomplete plain stitch structure. According to the arrangement order of the two coils in a complete organization, there are Swiss style and French style. The Swiss-style dot pattern has a compact structure, small extensibility and good dimensional stability. The French-style dot pattern organization has the characteristics of clear longitudinal lines, plump surface, and larger width. Both of these organizations are widely used in the production of knitted outerwear.
