Warp Knit

The most common product types are weft knitted and woven.  There does exist a third group of fabrics known as warp knits.  These warp knit fabrics possess the extensibility of knits along with the dimensional stability of a woven fabric which makes them an almost ideal textile material.  Unfortunately, the warp knitting process is very intensive and not ideally suited to staple spun yarns such as wool.  However, the advent of new spinning technology for knitting yarns makes warp knitting feasible for wool.  Warp knitting presents to the garment maker and designer, a new set of fabric structures ranging from woven looks to fine mesh and gauzes.   These fabrics have a more relaxed aesthetic than most woven fabrics and thus ideal for making more casual wool apparel.


The Technology

Warp knitting is best suited to synthetic filament yarns which can be very fine,  strong, uniform and unlikely to abrade and shed fibres.  The solution to using staple spun yarns is to combine the two, in the Sirofil spinning system which wraps a fine filament yarn around a core of wool.  The filament protects the yarn from the abrasive forces of the warp-knitting process and permits very fine fabrics in a new range of structures to be made .  If the filament is made from polyamide then fabric dyeing is feasible.  

Features & Benefits

  • Very fine and yet strong wool yarns are compatible with warp knitting
  • Wool-rich fabrics, up to 90%, are possible
  • Fabric strength is enhanced due to presence of filament yarn
  • Very lightweight fabrics possible on 28gg tricot machines
  • Piece-dyeing for quick response possible
  • Formal tailoring with a relaxed look
