Tuck Stitch Knitting Effects
A tuck stitch is a type of knitting stitch where a loop is held on the needle from a previous course while a new loop is formed and passes through it. Unlike a plain knit stitch where each loop is fully drawn through the previous one, the tuck stitch holds back one or more loops.
Mechanism of Fabric Change
- Loop Holding: When loops are held on the needle, it prevents the complete tightening of the stitch.
- Fabric Expansion: This holding action creates extra fabric or slack within the stitch structure. This slack causes the fabric to spread outwards, making it wider than fabric made with standard knit stitches.
- Increased Spacing: The structure formed by holding loops leaves larger gaps between the stitches. This increased space allows air to pass through more easily, making the fabric feel more porous.
Consequently, the characteristic properties of a fabric created using tuck stitches are increased width and a more open, porous texture.
