Knitting Principles

• Knitting is a fabric forming process that converts yarns into

fabrics and accounts more than 30% from the total textile

production According to the yarn feeding system, two

knitting techniques are known, namely weft and warp.

• By weft knitting, the loops are formed from a single thread

within the same row (figure 9.1), whereas the warp

knitting produces a fabric from warp yarns that run

vertically and parallel to each other (figure 9.2)

• The frame, which is an independent stand, designed to accommodate the majority

of machine’s mechanisms.

• The yarn feed consists of the yarn package or warp beam, tensioning devices, yarn

feed control and yarn feed carriers or guides.

• The knitting area includes the knitting elements, needle beds, drive and control, as

well as pattern selection.

• The fabric take-down mechanism includes fabric tensioning, wind-up and

accommodation devices.

• The quality control system includes stop motions, fault detectors, automatic oilers

and others, according to the machine developments.

• The machine control and drive system generating the power driving the devices and

mechanisms.
