Knitting is a method by which thread or yarn may be turned into cloth. Knitting consists of consecutive loops, called stitches. As each row progresses, a new loop is pulled through an existing loop. The active stitches are held on a needle until another loop can be passed through them. Basically there are two types of knitting which are weft knitting, versus wrap knitting and another type is flat knitting versus circular knitting.

Knitting

Knitting is the most common method of inter-looping and is second only to weaving as a method of manufacturing textile products. It is estimated that over 7 million tons of knitted goods are produced annually throughout the world. Although the unique capability of knitting to manufacture shaped and form-ļ¬tting articles has been utilised for centuries,modern technology has enabled knitted constructions in shaped and unshaped fabric form to expand into a wide range of apparel, domes- tic and industrial end-uses.

Types of Knitting

There are 2 types of knitting. One is Circular knitting (Tubular knit). Another is Flat knitting. Circular knit is used to knit body fabrics. Flat knit is used to knit Collars & Cuffs.

There is another type of flat knit machines which are used to make Sweaters (Tricot garments). With these machines, the body fabrics, sleeves and necks are being made. And they are joining together with the help of linking machines. We have to note that the attachments of these parts are done with the main yarns. No separate sewing threads are used for joining. Buyers use to call these garments as Knitted garments or Tricot garments or Sweaters. Mostly acrylic and wool yarns are used. Lower counts like 2’s, 4’s, 6’s, etc are used.

T shirts, polo shirts are also called knitted garments. As the body, sleeves, collars, cuffs are cut separately and joined together, some buyers use to call these garments as ‘Cut & Sewn Garments’.

There are 2 things making the knit fabric. They are Wales and Course. Wales is the vertical yarn. Course is the horizontal yarn.

Wales lines are fixed by the machine gauge. This can not be changed. Coarse lines can be altered by adjusting in the machine. This is called Texture.



Classification of Knitting Machinery

The machines used for the manufacturing of knit fabrics can be divided into machines with individually driven needles and needle bar machines.

The former type of machine incorporates needles which are moved individually by cams acting on the needle butt; they are used for producing weft knits and are subdivided into circular knitting machines and flat-bed knitting machines.

The needles used can be latch needles or compound needles. The needle bar machines incorporate needles which move simultaneously, since they are all fixed to the same bar; we distinguish full-fashioned knitting machines and circular loop-wheel machines for the production of weft knit fabrics, which only use spring-beard needles, and warp knitting machines which use spring-beard needles, latch needles and compound needles.
