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.

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stitch is identified by the fact that its head is released as a hump shape immediately the needle loop above it is withdrawn.

►A knitted loop would be required to be separately withdrawn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.
