  • 1. FABRIC SCIENCE-2 By :Chiluka Saikumar Knr13ap30 FP Technology Sem-2
  • 2. By : Vasant R Kothari Magazine : Knitting views March-April 2012.
  • 3. • Warp Knitting is defined as a stitch forming process in which the yarns are supplied to the knitting zone parallel to the selvedge of the fabric. ,i.e. In the direction of wales. • In Warp knitting machine, every knitting needle is supplied with at least one separate yarn. In order to connect the stitches to form a fabric ,the yarns are deflected laterally between the needles.
  • 4. As compared to weft knitting in warp knitting also, the wales and course are respectively called as overlap and under lap.
  • 5. • The warp knitted fabric structure has dissimilar appearance on the technical face and technical backside of the fabric. • All warp-knitted fabrics can be identified and distinguished from weft knitted materials by careful examination of the face and back of the fabric, usually with the help of a Pick glass.
  • 6. • The face side of the fabric has rather clearly defined knit stitches generally running vertically, but slightly angled from side to side. • The technical backside of the fabric, the diagonal line of yarns i.e.underlaps run right And left throughout in a zigzag manner.
  • 7. Overlap Underlap • The under laps play a very important role in the pattern effects. The length or extent of these underlap floats and their direction of running cause a variety of designing possibilities.
  • 8. Loops are termed ‘Laps’ in warp knitting because the warp guides lap their yarn around the needles in order to form the loop structure. WARP KNITTED STRUCTURE The stitch(overlap) The linking(underlap)
  • 9. The formation of Stitch in warp knitting using a compound warp knitting needle.
  • 10.  Extremely versatile in pattern effects with yarn.  Rigid to elastic  Good air and water permeability  Good crease resistance  Good drapability  Good dimensional stability  Good strength.
