Classification of Knitting Machines-Knitting Technology

The machines used for the manufacturing of knit fabrics can be divided into machines with
individually driven needles and needle bar machines.

The former type of machine incorporates needles which are moved individually by cams acting
on the needle butt; they are used for producing weft knits and are subdivided into circular
knitting machines and flat-bed knitting machines.

The needles used can be latch needles or compound needles.

The needle bar machines incorporate needles which move simultaneously, since they are all
fixed to the same bar; we distinguish full-fashioned knitting machines and circular loop-wheel
machines for the production of weft knit fabrics, which only use spring-beard needles, and warp
knitting machines which use spring-beard needles, latch needles and compound needles.

Knitting Technology | Weft and Warp Knitted Fabrics | Difference Between Weft and Warp Knitting

 

Knitting: Knitting is the method of creating fabric by transforming continuous strands of yarn into a series of interlocking loops, each row of such loops hanging from the one immediately preceding it. The basic element of a knit fabric structure is the loop intermeshed with the loops adjacent to it both sides and above and below it.

In the simplest form, a knit fabric is made by the longitudinal and vertical repetition of the same element, the loop, which is the basic element of the fabric.

The loop is a length of yarn that is forced to assume a curvilinear shape. It can be divided into three main sections

a) Loop top
b) Loop side and bottom
c) Half interloop (The interloop is the yarn that links two consecutive loops)

Knit fabrics are mainly categorized into two types respectively WEFT Knitting & WARP Knitting. The horizontal or vertical
repetition of loops forms the typical structures of knit fabrics, which can be divided into WEFT
KNIT FABRIC and WARP KNIT FABRIC, respectively.


WEFT KNITTING: In a weft knitted structure a horizontal row of loops can be made using one thread and the thread runs in horizontal direction.

WARP KNITTING: In a warp knitted structure, each loop in the horizontal direction is made from a different thread and the number of threads used to produce such a fabric is at least equal to the number pf loops in a horizontal row. One can say that in a warp knitted fabric the threads run roughly in a vertical direction.

What is a Course and Wales?

The word “course” defines a row of horizontal loops, belonging or not to the same yarn; “wale”
means a row of loops laid vertically one upon the other

Measuring GSM of Fabric Without GSM Cutter | Woven Fabric GSM Measurement

GSM is the short form of Grams per Square Meter. GSM is the very most important thing which defines the weight of the fabrics of knit garments.

Garment price and quality based on many things like GSM, fabric quality, colors, finishing, prints, embroidery, style, etc. But GSM is the most important thing to be decided when confirming the prices between the sellers and buyers.

If we have fabrics, then we don’t have any problem in finding GSM, as we can cut any dimension to find GSM. But most of the times, we will have only the garments to find GSM. And we will have to keep the garment for style, making and other references. So we will be allowed to cut a small bit from the garments. Hence nowadays, round cutters are used. This system is used worldwide. With the help of this round cutter, the fabric will be cut into a small bit.

Then the GSM of the fabric can be found out by multiplying the weight of this round bit by 100. This round bit is to be weighed in an electronic scale with milligram accuracy. As this bit is very small and as the weight has to be multiplied by 100, the fabric has to be cut very sharply to get the exact GSM. Hence the blades of this round cutter are to be  sharp and new to get the exact GSM.

Now we will measure GSM in general procedure (In case of woven garment it is frequently used)

 GSM is the weight of 1meter x 1meter fabric. It means 100cm x 100cm = 10,000 sq.cms. It can be found out by any one of the below ways.

·         By the weight of 100cm x 100cm fabric bit.

·         By the weight of 50cm x 50cm fabric bit multiplied by 4.

·         By the weight of 25cm x 25cm fabric bit multiplied by 16.

·         By the weight of 10cm x 10cm fabric bit multiplied by 100.

We must be aware that if we use the smaller size bit, accurate GSM can not be achieved. The bigger size of fabric bit is better used to get exact or closer GSM.
