7.4.3.2 Warp knitting
Warp knitting is a technique in which the yarns forming the loops run in length direction of the fabric. The loops are connected laterally by moving the warp yarns sideways. The loops are formed simultaneously across the width of the knit. This requires several yarns, usually wound on a warp beam.
Advantages of warp knitted fabric:
Does not fray (unravel)
Does not ladder
Less stretchable than weft knitted fabric
Coarser yarns can be used
Higher production rate
Disadvantages of warp knitting:
Less stretch than weft knit
Not applied for small production quantities
More expensive than weft knit because a warp has to be made
