  2. Knitting is a process of manufacturing a fabric by the intermeshing of loops of yarns. The two main forms of knitting technology are Warp knitting Weft knitting introduction

  3. COURSES: Rows of loops across the width of the fabric produced by adjacent needles during the same knitting cycle. (measured in courses/cm). WALES: Vertical column of needle loops. Determines the width of the fabric (measured in Wales/cm). STITCH DENSITY: Represents the total number of needle loops in a given area. STITCH LENGTH: is the length of yarn in knitted loop. KNITTING TERMINOLOGIES

  4. Direction- horizontal WEFT KNITTING

  5. Direction-vertical Warp knitting

  6. knitting needle types

  7. Circular knitting machine

  8. Knitting cams • Clearing cam/Rising cam • Stitch cam • Running cam/ upthrow cam • Guard cams

  9. New yarn is taken Previous loop formed goes below the latch Needle goes to a maximum height The hook pulls the new yarn & loop is formed General loop formation of weft needle

  10. Warp knitting machine

  11. Loop formation of warp knitting machine • Start of new course • Start of overlap • Guide bar swinging motion • Return swing after overlap • Old loop closing latch • Knock over & underlap movements

  12. Full tricot locknit Warp knitted structures

  13. Three needle sharkskin Three needle queenscord

  14. Basic weft knitted structures • Simplest & most widely used weft knit structure • Fabric unroved from end • Fabric tends to curl at the edges • Production rate is high

  15. Rib knit structure • It is reversible structure • It gives a balanced structure • Fabric does not curl • Maximum extensibility in widthwise direction • Rib structure can not unroved

  16. Purl knit structure • Consists of reverse & face courses • Very little commercial & apparel end use • Extensibility in length wise direction • Fabric does not curl • Suitable for socks & sportswear

  17. Interlock fabric • It gives a reversible appearance • Fabric is firm • It does not curl at edges • Production rate is reduced to half • Structure is thicker, stronger & less elastic • Cost of fabric is high

  18. Comparison of weft & warp knitting

  19. Fabric structure Fibres type Stitch length Relaxation Yarn linear density Factors affecting on dimensional properties

  20. Comparison between Woven, Knitting and Non-woven

  21. Geotextiles Coverings Safety textile Industrial textile Medical textile Composites sportswear Nets Applications of Knitted Fabric

  22. The world produces over 17 tons of knitted textiles and apparel - representing one third of the global textile market. Moreover, output is forecast to grow by 25% over the next ten years, reaching more than 21 tons. Markets for Technical Textiles

  23. Cost of fabric
