Basic Technology General Remarks

A discussion about knitting technology must be dealt both as an analysis of the technical cycles of knitting as regards the machines used and the mechanisms involved in the process, and as an analysis of the technology of knitted fabrics in terms of their structures and their physical and mechanical properties.

Knitted Structures
Picture 1 - Knit fabric

In its simplest form, a knit fabric (picture 1) is made by the longitudinal and vertical repetition of the same element, the loop, which is the basic element of the fabric.

Loop Length Knitted Fabric
Picture 2 - The loop

The loop (picture 2) is a length of yarn that is forced to assume divided into three main sections: a: loop top b: loop side and bottom c: half interloop

The interloop is the yarn that links two consecutive loops together. The horizontal or vertical repetition of loops forms the typical structures of knit fabrics, which can be divided into WEFT KNIT FABRIC and WARP KNIT FABRIC, respectively.

Knit Loops

In weft knits (picture 3) the interloop links two consecutive loops placed horizontally; when one loop breaks, the entire fabric can be undone simply by pulling the free end of the yarn. In warp knits (picture 4) the yarn is knitted vertically or diagonally and loops are formed accordingly; to knit the fabric, it is necessary to use many threads simultaneously, allowing the loops formed by the different threads to bind together.

In this case, the knit fabric is run-proof . Therefore, the warp knit fabrics are also called "non-run" or "ladder-proof "

From a physical point of view, a fabric can be described as a flexible structure, made up by the vertical and horizontal repetition of two elements: the course and the wale. The word "course" defines a row of horizontal loops, belonging or not to the same yarn; "wale" means a row of loops laid vertically one upon the other (picture 5).
