Difference Between Warp and Weft

Warp : Most Garments are cut in lengthwise direction.

Weaving is the name given to the interlacing of two sets of yarns, warp and weft at right angles and the fabric thus formed is woven fabric.The warp yarns are those yarns which lie in the length direction of a fabric while it is being woven.

The weft or filling yarns are those which, during weaving are introduced between the warp yarns, across the width direction of the fabric. The warp are also known as ends and wefts as picks. The lengthwise edge of the fabric is called selvage (Self + Edge) Grain indicates a direction parallel to either the warp or filling yarn. The direction not parallel to either of these yarns is called off grain. Woven fabric will elongate most in a direction that is 45 o to both sets of yarns and this direction is called Bias.

Difference Between Warp and Weft

Warp

1.                 Most Garments are cut in lengthwise direction.
2.                 These are parallel to the selvedge
3.                 Yarns are finer in warp-wise direction as they have higher twist as warps have to go through lots of processing.
4.                 Filamentous yarns are preferred as warps
5.                 Yarns are stronger
6.                 Twist is more and yarns per inch is also more
7.                 Ply are preffered for warps.
8.                 Stretchability is low
9.                 Plain yarns are more preferred.

Weft

1.                 Some garment details such as collars are cut in this grain for decoration
2.                 Weft are perpendicular to selvedge
3.                 Yarns may be thicker or finer with medium twist
4.                 Spun yarns are used
5.                 Weaker yarns can also be used
6.                 Twist and yarns per inch is less.
7.                 Singles can be used.
8.                 Stretchability is high
9.                 Novelty yarns and textured yarns can be used.
