Fully Fashion Knitwear

Knit fabric Stitches/Design

Different types of stitches/design used in fully fashioned knitwear:
Basic Category:
  • Jersey stitch
  • Rib category/ stitch
  • Double jersey
Fancy Category:
  • Shaker or half cardigan stitch
  • Full cardigan stitch
  • Drop knit
  • Tuck knit
  • Milano stitch
  • Pointal stitch
  • Zigzag stitch
  • Cable (different types)
  • Diamond (different types)
Single Jersey/ Single Knit/ Plain Knit/ Basic Type Stitch:
  1. Appearance: Technical face has V shape stitch/ jersey stitch and Technical back has semi circle stitch.

Stitch diagram of Single Jersey:

  • Semi circle stitch is also known as purl stitch because it looks like purl.

  1. Edge curling: Normally occurs T/F to T/B in lengthwise direction but sometimes occurs T/B to T/F in widthwise direction. The reason of it is yarn tension/ torque because the back needles were inactive during manufacturing.

  • Edge curling is a disadvantage because it hampers productivity in linking section.
  • Tension is a tightness or looseness factor of knitted structure.
Remedies of edge curling:
  • After knitting before linking use iron at the edges.
  • We can also use folder or attachment during linking.
  1. Dimensional stability: Dimensional stability is comparatively poor than other knit.
  • Dimension means shape. After stretching the fabric if it recovers to original shape dimensional stability is good and if does not recover properly stability is poor.
Methods of increasing dimensional stability:
  1. Increase loop density (for both light & heavy knit fabric)
  2. Apply resin finish (for light knit fabric, if buyer required because it stiff the fabric)
  1. Unraveled: We can unrope the yarn from the both end.
  1. Elasticity (stretch ability): Almost same/ equal elasticity both in lengthwise and widthwise direction.
  • Laddering: Laddering can be repaired in flat bed knitting but not in circular knitting.
It is a defect which occur because of-
  1. Needle head broken. So needle cannot catch the yarn and yarn loops slips.
  2. Poor quality yarn which has slub.
  3. Loose tension.
