What Are The Considerable Points For Producing Knit Fabrics?

Knit fabrics are the fashion of new age. Various designed fabrics are produced in knitting machine. Knitting flow chart should follow during operation. During production process following machine parameters are considered.

  • Machine diameter
  • Machine rpm (revolution per minute)
  • No. of feeder in use
  • Machine gauge
  • Count of yarn
  • Required time
  • Machine running efficiency

Considerable points to produce knit fabrics: Generally knit fabric production runs according to the order of buyer. When a buyer orders for fabric, they mention some points related to production and end product quality. Before production of knitted fabrics, these factors are needed to consider. Those are as follow:

Type of fabric or design of fabric: Knitted fabrics are various in design. When a buyer order for a product they give a sample or give the specification of the end product. Different designed fabrics are produced by changing the cam setting, needle setting and size of loop shape.

Finished G.S.M: It is technical term that indicates the weight of the fabric per square meter. In knitting section grey fabrics are produced but the programer should make his program for getting the finished G.S.M after dyeing. Some points are considered while setting grey G.S.M; they are enzyme level, color and suided or non suided. G.S.M of the fabric is controlled by the following way:

→Major controlled by VDQ pulley.

→Minor controlled by stitch length adjustment.

→By altering the position of tension pulley, G.S.M of the fabric can be changed. If pulley moves towards the positive directive then the G.S.M is decrease and in the reverse direction G.S.M will increase. This also depends on the machine type.

Yarn Count: Yarn count differ on the finished G.S.M. Higher the yarn count higher the G.S.M of the fabric. Sometimes spandex or lycra is used with the cotton in that’s case yarn count of cotton select with the combination of lycra.

Type of yarn: Different types of yarn is used for knit production. Cotton yarns may be combed or carded. Also synthetic fiber like lycra is used with cotton for some special case. All depends on the buyer requirement.

Diameter of fabric: Diamter of the fabric is another factor. Fabric may be open diameter or tube diameter. Any how grey dia. will be selected with response of finished dia. of the fabric.

Stitch length and color depth: If the depth of color of the fabric is high then loop length should be higher because in case of fabric with higher loop length is less compact. In dark shade dye take up% is high so G.S.M is adjusted then. Similarly in case of light shade loop length should be relatively smaller. Stitch length vary depending on yarn count and shade of the fabric. If stitch length is not fixed with respond to finished G.S.M then knitting faults appear.

So, we have to consider above points before knit fabrics production.
