Unit 1: Basic knitting terms and definitions (course, wale, CPI, WPI, stitch density, loop length),

Comparison of weaving and knitting, comparison of warp and weft knitting, Preparation of yarns for weft and warp knitting; Classification of weft knitting machines; Structural Elements of Weft Knitting: Needle loop, sinker loop, technical face, technical back, knit stitch, tuck stitch, purl stitch, miss stitch, needle numbering system Total lectures required=6

Unit 2:Mechanical elements of weft knitting: needles, and their types (latch needle, bearded needle and

compound needle), sinkers, cams, cylinder, jack; knitting action of all needles; Knitting cycle and yarn path of weft knitting; Four basic weft knitting structures- single jersey, rib, purl and interlock (their structures, loop formation, machine construction, fabric characteristics, use and derivatives), Circular weft knitting machines Total lectures required=8

Unit 3: Flat bed knitting machine: Process of loop formation, cam track, features, and structures produced;

Relation between yarn count and machine gauge; Science of Knitting: Concept of loop length, loop length geometry, knitting tension, fabric relaxation and shrinkage, tightness factor, robbing back, spirality, all related numerical Total lectures required=7
