Plain Single Jersey Fabrics Overview

A weft knitted fabric with one side of face stitches and the other side of back stitches. It's the simplest structure made with one set of needles.

The side of the fabric with smooth knit stitches, creating a smooth texture.

The side of the fabric with purl stitches, creating a textured appearance.

Another name for a plain knitted fabric.

Very low because both the stitch structure and the machines are simple.

Stretch is both crosswise and lengthwise, with more stretch in the crosswise direction.

Plain jersey fabric is less stable and tends to curl when cut; special finishes can improve stability.

Adjustable with cam settings. Shorter stitch length leads to more courses per unit length.

The distance between stitches on a fabric.

The tendency of fabric edges to curl after being cut.

A characteristic of jersey fabric where it curls at edges due to loop-pulling direction in one needle bed.

Method of creating single jersey fabric on flat or circular machines.

Machines that produce fabric in tubes, with moving needles and stationary cams.

(in knitting) The process of delivering yarn to the needles.

Step in knitting where the sinker holds the old loop while the needle rises.

Step in knitting where the sinker holds and needle is raised to clear old loop.

The process where the sinker fully retracts, trapping the new yarn while the needle descends to push the old loop onto the sinker belly.

The sinker moves forward to secure the new loop in its throat while the needle rises back to its resting position.

Mechanical elements in a knitting machine responsible for guiding needles and sinkers during the knitting process.

A cam that removes the old loop from the needle.

A cam that adjusts the stitch length by changing the distance the needle travels.

A cam that guides the sinker through its movements during the knitting cycle.

A knitted fabric with vertical rows of loops that interlock in opposite directions, creating a textured appearance.

Jersey knits are used in a wide range of products, from sheer fabrics to thick sweaters, including hosiery, T-shirts, and knit terry.

Rib fabrics have a vertical cord appearance due to the movement of face loop wales over and in front of the reverse loop wales.

The rib structure where stitches lie in two planes, one for face loops and one for back loops.

The simplest rib fabric with alternating wales knitted to the front and back, creating a double-faced appearance.

1 x 1 rib fabric has twice as much recoverable stretch in the width direction compared to a plain fabric of equal thickness.

Rib fabrics are typically produced on V-bed or circular knitting machines with two sets of needles positioned at right angles.

1 x 1, 2 x 2, and 3 x 3 rib fabrics are reversible, meaning both sides have the same appearance.

Rib fabric is inherently thicker and heavier than a plain knit fabric with similar gauge.

Rib fabric doesn't curl easily due to its balanced structure, making it ideal for cutting and sewing.

The process where the dial needle retracts first and then pushes the old loop off the needle, making way for a new loop to be formed.

The relationship between the positions of the dial and cylinder needles when they form loops, measured as the distance between their knock-over points.

When both cylinder and dial needles knock over simultaneously to create loops of equal size.

When the cylinder needle knocks over before the dial needle, creating a tighter fabric with a rob-back effect.

A fabric with interlocked loops creating a textured appearance, also known as link-link fabric.

A variation of rib knit fabric with a less pronounced rib structure.

Rib knit fabrics are widely used for apparel items like collars, cuffs, necklines, and knit hats.

They are known for resembling small pearl droplets, hence their name.

A knit fabric with a textured appearance produced by a special knitting machine that creates purl stitches.

Purl knit machines utilize a double-headed needle system to create the characteristic purl stitch. The needles move back and forth between the two needle beds, creating a textured surface.

Purl knit machines are incredibly versatile, able to produce plain, rib, and purl fabrics, making them popular in the sweater industry.

The cost of producing purl knit fabrics is higher due to the slower production rate of the specialized machines.

The machine uses sliders to transfer the needle between the two needle beds, engaging the needle hook and controlling the yarn feeding to create the characteristic purl stitch.

The slider in the back bed moves the needle to a 'knock-over' position, securing the yarn and completing the purl stitch.

The needle is positioned differently during the purl stitch, causing the yarn to be fed to the opposite end of the needle compared to a regular knit stitch.

Jersey knit machines have the highest productivity but the lowest versatility, while purl knit machines are the opposite.
