Knitting Knitting is a method by which thread or yarn is

used to create a cloth. The knitted structure consists of one set of yarn, weft or warp and is divided into weft knitted fabric and warp knitted fabric.

Classification of Knitting• Warp Knitting.• Weft Knitting. Warp Knitting: A type of knitted fabric construction in which the

yarns are formed into stitches in a lengthwise manner. Warp knits are generally less elastic than weft knits. Common examples of warp knits are tricot knits and raschel knits.

Classification of Knitting

Weft Knitting: A type of knitted fabric in which yarns are

formed into stitches in widthwise manner. Common examples of weft knits are circular knits and flat knits.

Warp Knitting

The stitches are produced in each course simultaneously. Warp knit structure are as following kinds:

Milanese knit. Raschel knit. Tricot knit Crochet Knit

Milanese knit

The Milanese stitch produces a fabric very similar to tricot. It can be identified by the fine rib on the face & a diagonal pattern on the back. However, Milanese fabric is superior to tricot in smoothness, elasticity, regularity of structure & friction resistance.

Raschel knit.

The Raschel knit ranks in importance of production with tricot but it makes varieties of products ranging from laces, power nets for foundation garments, swimwear to carpets. Raschel knitting is done with heavy yarn & usually has a complex lace-like pattern.

Tricot knit

Tricot fabric is soft, wrinkle resistant . Tricot knits are used for a wide verity of fabric weights & design. It makes light fabric weighting less than 4 ounce/square yard. Some examples of tricot fabric are sleepwear, boluses, dresses etc.

Crochet Knit

This basic stitch is used in hand crochet. This construction is used in a wide variety of fabrics ranging from nets & laces to bed spreads & carpets, various types of edgings or trimmings lace are also produced.

Weft Knitting

The following is a list of name of knit fabrics which are commonly used to produced knit garments with weft knitting:

Plain/Single/ jersey knit Pique knit/ La-cost knit Interlock knit Rib knit Terry knit Fleece knit Jacquard knit Yarn dyed stripe knit Feeder stripe knit Engineered stripe knit

Plain/Single/ jersey knit People call it jersey knit. Plain is produced by

the needles knitting as a single set, drawing the loops away from the technical back and towards the technical face side of the fabric. It use as ladies hosiery.

Pique knit/ La-cost knit

Pronounced “PEEK”, this is the fabric that is most associated with the original Lacoste Alligator Polo shirt. Also sometimes called mesh, pique is characterized by a textured fabric face with lots of tiny holes and a fabric back that is smooth.

Rib knit

A basic stitch used in weft knitting in which the knitting machines require two sets of needles operating at right angles to each other. Rib knits have a very high degree of elasticity in the crosswise direction. This knitted fabric is used for complete garments and for such specialized uses as sleeve bands, neck bands, sweater waistbands, and special types of trims for use with other knit or woven fabrics. Lightweight sweaters in rib knits provide a close, body-hugging fit

Rib knit

There are 1X1 rib, 2X1, 2X2, 3X1, 3X2, 3X3, 5X2 ribs & so on. You count the number of ribs in front & on back to determine what it is.

Interlock knit

A weft knit process producing a compound fabric. Two 1X1 rib fabrics are interlocked or inter knitted to form on cloth & are characterized by fine ribs in the lengthwise direction on the both sides of the goods. The two rib courses are defend as one interlock course.

Terry knit

A woven or knit uncut loop structure produced as single faced with loop formation on face & back. Size , shape & density of loop formation may vary. They look like terry towel.

Fleece knit

One side loops like jersey, the other side heavily brushed it is known as fleece knit.

Jacquard knit

It is a system of producing a patterned knit fabric incorporating the jacquard system. The system is the individual control of the selection or inhabitation of the needles to produce the design or pattern utilizing.

Yarn dyed stripe knitIn making color knitted fabrics, we usually would

use the following methods to color them: Piece dye: for solid colors. Yarn dye: for horizontal stripes. Printing: for printed designs.

For piece dyed solid colors & prints, the process of manufactures is pretty much the same as woven fabrics.

Feeder stripe knit

The means you feed the knitting machine with yarn of different colors & let the machine knit as if knitting solid color fabrics.

Engineered stripe knit

When the size of the repeat of the stripe you need is bigger than 2” it is beyond what the feeder stripe method can do & you will have to use “Engineered Stripe” method to make this knitted fabric.
