GENERAL TERMS RELATED TO KNITTING TECHNOLOGY

Kink of yarn:

A length of yarn that has been bent into a shape appropriate for its transformation into a weft knitted loop.

Knitted loop:

When intermeshed two kinks of yarn is called loop.

Knitted stitch:

Usually consists of three or more intermeshed loops, the center loop having been drawn through the head of the lower loop which had in turn been intermeshed through its head by the loop which appears above it.

Top arc:

The upper curved portion of the knitted loop is called the top arc.

Bottom half-arc:

The lower curved portion that constitutes a weft-knitted loop, half of the connection to the adjacent loop in the same course.

Legs or side limbs:

The lateral parts of the knitted loop connect the top arc to the bottom half-arcs.

Needle loop:

Needle loop formed by the top arc and the two legs of the weft knitted loop

Needle loop= Top arc+ Two legs

Open loop:

A knitted loop of which a thread enters and leaves at the opposite sides without crossing over itself.

Closed loop:

A knitted loop of which a thread enters and leaves at the opposite sides crossing over itself. It is made by a special needle

Course:

A course is a predominantly horizontal row of loops (in an upright fabric) produced by adjacent needles during the same knitting cycle.

Wale:

A wale is a predominantly vertical column of needle loops produced by the same needle knitting at successive knitting cycles and thus intermeshing each new loop through the previous loop.

Stitch density:

It is the total number of needle loops in a square area measurement such as a square inch or square centimeter.

Stitch density= Wales per inch (wpi) x Courses per inch (cpi).

Loop or Stitch length:

The length of yarn knitted into one stitch in a weft-knitted fabric. Stitch length is theoretically a single length of yarn that includes one needle loop and half the length of yarn (half a sinker loop) between that needle loop and the adjacent needle loops on either side of it.

Stitch Length, I = one needle loop+ two half a sinker loop.

Extended sinker loop:

A sinker loop that is wider than the other sinker loops in the fabric that is produced when a needle is inactive or has been removed from the needle bed or needle bar.

Face loop or stitch:

Also called plain stitch or jersey stitch or flat stitch. A stitch that is so intermeshed in the fabric that its legs are situated above the top arc of the stitch formed in the same wale in the previous course.

Reverse or back loop or stitch:

Also called purl stitch. A stitch that is so intermeshed in the fabric that the top arc and the bottom arcs are situated above the legs of the stitch formed in the same wale in the previous and in the following course
