How to Determine Warp and Weft in a Woven Fabric?

There are many reasons to know the warp direction of the fabric before you go for using it. To make it easy for determining warp and weft in a fabric piece observe the following characteristics of the fabric yarns.

Yarn Strength: Warp yarns are stronger compared to wefts


Yarn appearance: Warp yarns are comparably finer than weft yarns and comparably higher twisted yarn.

Stripe/check patterns: If fabric got coloured stripes then stripe direction shows warp (mostly). In checks, if you find one colour with odd numbers of threads, it is warp.

Characteristics
Warp
Weft
Selvage  (If you got fabric with edges)
Then it is easy to determine warps as parallel yarns with selvedge is warp.
And yarns those are perpendicular to the selvedge are weft or filling yarn.
Pull the yarn
Comparably difficult to pull out warps from fabric.
Comparably easier to extend from fabric
Reed mark (View under strong light)
1.      Reed mark – you will find gaping after each pair of yarns.
2.      Better regularity
3.      Straighter
1.      No reed mark
2.      More irregularity
3.      Less straight
Size (starch coating)
Warps are coated with size materials
No size
