Technical face (closed lap) Technical back (closed lap)2 x 1 plain (2 x I lap) tricot differs technically from the half tricotconstruction by the underlappings which are increased by one needle space sothat each sinker loop in the texture moves one wale, The longer sinker loopalso alters the properties of the fabric (more rigid)
