What is Loop Transfer | Properties and Uses of the Transferred Stitch

What is Loop Transfer?
A loop that is displaced after being formed so that it combines with an adjacent loop, or so that it appears in a different wale, is said to have been transferred.

Loop transfer is done to achieve shaping, produce a design, or change the stitch structure. Transferring is used to generate holes in the fabric to form lace-like effects. Transferring can be used to produce structural effects by inclining wales of both plain and rib fabrics. This is also used to produce cables by exchanging two or more groups of wales with one another.

Properties and uses of the Transferred Stitch:
Loop transfer is widely used in flat knitting for various reasons, some of which are described below:

1. Changing from rib to plain: Often, garments are produced with a rib welt, which provides elastic properties, and then continues as a plain construction to reduce thickness and weight. In these cases, all the loops participating in the production of the rib welt are transferred to one needle bed. The plain knit structure continues to knit on this single bed.

2. Knitting purl knits: To knit purl knit structures containing face and back loops within the same wales, loops should be transferred between front and rear needles.

3. Patterning: Transferred loops are widely used in fabric patterning. Wale distortion is one example, in which certain wales are moved from needle to needle which then continue to knit through them.

4. Shaping: Sophisticated knitting machines are able to shape the garment rather than to produce only rectangular panels. Panel shaping requires needle selection and transferring ability, in which loops are transferred inward at the edges, to facilitate narrowing. Since the loops are transferred from one needle bed to the other, which is then racked to allow the return procedure, the efficiency and productivity of the machine is reduced. The profitability of the process should be considered by weighing together the raw material costs and the reduction in cutting operations, against the knitting efficiency and productivity.

Types of Transfer Stitches:
There are four types of transfer stitches:
  1. Plain needle loop transfer stitches: It is produced by transference of a loop from one needle to another in the same bed.
  2. Fancy lacing stitches: It is produced by modification of the plain loop stitch.
  3. Rib loop transfer stitches: It is produced by transferring a loop from one needle bed to the other.
  4. Sinker loop transfer stitches.
