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
