Tuck Stitch and it’s Formation Process

 Tuck Stitch

                                          

 Features of tuck stitch

A tuck stitch is composed of a held loop, one or more tuck loops and knitted loops.

It is produced when a needle holding its loop (T) also receives the new loop, which becomes a tuck loop because it is not intermeshed through the old loop.

The tuck loop thus assumes an inverted V or U-shaped configuration.

The head of the tuck is visible  on the reverse of the stitch.



Notation of tuck stitch

The side limbs of tuck loops thus tend to show through onto the face between adjacent wales.

Tuck stitch structures show a faint diagonal line effect on their surface.

In analysis, a tuck stitch is identified by the fact that its head is released as a hump shape immediately the needle loop above it is withdrawn.

A knitted loop would be required to be separately withdrawn

 Effect of tuck stitches

Fabric with tuck stitches is thicker than knit stitches due to accumulation of yarn in stitches at tucking places.

The structure with tuck stitches is wider than with knit stitches as the loop shape has a wider base.

As the loop length is shortened, the tuck stitched structure is less extensible.

Due to thicker in nature, the tuck stitched fabric is heavier in weight per unit area than the knit stitches.

Tuck stitched structure is more porous and open than the knit stitched fabric.

Tuck stitch is also used to get fancy effects by using colored yarns.

Tuck loops reduce fabric length and length-wise elasticity because the higher yarn tension on the tuck and held loops causes them to rob yarn from adjacent knitted loops.

Fabric width is increased because tuck loops pull the held loops downwards, causing them to spread outwards and make extra yarn available for width-wise extensibility.

Fabric distortion and three-dimensional relief is caused by tuck stitch accumulation,   displacement of wales, and by varying numbers of tuck and knitted stitches per wale.

The tuck stitch may also be employed to produce open-work effects, improve the surface texture, enable stitch-shaping, reinforce, join double-faced fabrics, improve ladder-resistance and produce mock fashion marks.
