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.
