KNITTING



KNITTING

Knitting is interloping of yarn to form a fabric.It is 3d fabric bought and sold by weight or

tube (in gms or kg).



STRUCTURE

COURSE A course is a series of successive loops lyingcrosswise of a knit fabric , thatis,at right angles to a linepassing through the open

throat to the closed end of theloop.

WALES

Wale refers to a column of loops that are parallel to loopaxis. The wales also runparallel to the longmeasurement of a knit fabric.



TYPES OF KNITS

WEFT KNITTING

When the yarns areintroduced in a crosswisedirection, at right angles tothe direction of growth of the fabric, and run or

interlock across the fabric, All the loops in one course

are produced from singlesupply and loops areformed in successive order one by one.



Four basic stitches used in

manufacturing weft knits:

Knit and purl stitches

The knit stitch is just pulling

a loop of yarn through an

existing loop on the

needle. Pulling it through

with the yarn in the back

creates the knit stitch.

Pulling it through withthe yarn in front creates

the purl stitch.



RIB STITCH

made on V bed machine

Stitches intermesh inopposite directions

Frequency of intermeshing determines

type of ribINTERLOCK STITCH

Variation of rib stitch

Resembles two separate1×1 rib fabricsinterknitted

Identical on both sides



KNITTED PILE FABRIC

Based on double knit technique

An extra set of yarn is drawn out of loops

and left cut or uncut.



Tuck stitch is made when a needle takes a

new loop without clearing the previouslyformed loop, so that loops are accumulated

on the needles.



Miss stitch is produced by a needle holding

the old loop (the needle is not raised, which

effectively means the needle is missed),

while the adjacent needles are raised and

cleared to produce a new knitted loop.



Warp knitting

A warp knit fabric isconstructed with manyyarns that form loopssimultaneously in thelengthwise (warp)direction. Each yarn iscontrolled by its ownneedle, and interlockedwith neighbouring yarnsin zigzag fashion.

This interlockingproduces fabrics thatare usually runproof andhave limitedstretchability



TRICOT WARP KNITTING Each warp yarn is knitted by one needle. All the

needles of the machine are mounted in one

needle bar. When the needle bar is activated, all needles

act in unison to produce stitches simultaneouslyfrom parallel warp yarns.

These parallel ladders of stitches are heldtogether and are not a multitude of fine, parallel,

looped yarns, each independent andunattached.



Milanese knits

method of warp knitting similar to tricot

resultant is fabric is similar but machinery isquite different.

disappearing from the market because theproduction rate is low and the pattern

possibilities are severely limited.



Raschel fabrics: Theprinciple of knitting inraschel knits is identicalto tricot knits.

The significantdifferences between tricotand raschel are thatraschel knittingmachinery utilizes latchneedles rather thanspring beard needles

Fabrics ranging from finelaces to heavy blanketsand even carpets can beproduced. Interested

surface effects and threedimensional effects canalso be produced. Spunand filament yarns of allcounts and deniers canbe used.
