How does the stitch density influence the areal density GSM of knit fabric?

The results of this research work indicating that areal density (GSM) and drape co-efficient of weft knitted fabrics are directly related to the stitch length, yarn count and knitted structures. It was observed that higher GSM and higher drape co-efficient were obtained with smaller stitch length.

How do you increase the GSM of knitting fabric?

GSM can be controlled either by taking a coarse count of yarn. Or for the same count of yarn increasing the stitches per inch. Stitch per inches can be increased by either resorting to a higher gauge machine or by decreasing the loop length.

What is areal density of fabric?

Areal density is the measure of mass per unit area of the fabric. Usually knit fabrics with tuck stitches appear thicker than the fabric having only knit stitches due to accumulation of yarns at the tucking places [4].

What is GSM in knitted fabric?

GSM means grams per square meter. Fabric weight is expressed by GSM. For example, the lighter the fabric, the lower its bending rigidity. … GSM is an important parameter of knitted fabrics which is very essential for a textile engineer for understanding and production of fabric.

What is GSM knitting?

GSM stands for Gram per square meter (gm/m2) and represent the weight of one square meter of knitted fabric in grams. … This means, if the stitch is longer, than there are less courses per inch which implicate lighter fabric (lower GSM).

How is fabric GSM calculated?

Cut 5 swatches from the different places of the fabric. Weight all test swatches accurately and calculate the average weight of swatches. Multiply the average weight of swatches by 100 to calculate the GSM of the sample fabric.

What does 120 GSM mean in fabric?

GSM in fabric, also known as grams per square metre is simply the metric measurement of the weight of a fabric. … The higher the GSM number, the denser the fabric will be. For example, if the label on a linen shirt reads 180-200 GSM, the shirt material would be thick and would probably keep one warm.

How do you find the density of a stitch?

Stitch density = (WPI × CPI) inch-2 = (WPC ×CPC) cm-2. No of sinker = No of needle. No-Wales =No of needle. No, of course, = No of feeders =No of yarn (per revolution of cylinder)

What is stitch length in knitting?

The length of yarn required to produce a complete knitted loop is known as stitch length or loop length. Stitch length is a length of yarn which includes the needle loop and half the sinker loop on either side of it.

What is areal density hard disk drive?

Areal density is a measurement of the amount of data that can be stored on a given unit of physical space on storage media. It is most frequently measured in gigabits per square inch and used to describe hard disk drive capacity.

Why is GSM important?

The most obvious advantage of GSM is its widespread use throughout the world. According to, GSM has a harmonized spectrum, which means that even though different countries may operate on different frequency bands, users can transfer seamlessly between networks and keep the same number.

Why GSM is important in textile?

It’s vital because the weight of the fabric depends on this value. The higher the GSM of a fabric is the higher the weight. Thus, if two fabrics are composed of the same material, than the one that has a higher GSM value will cost you more. It’ll be thicker also.

What is GSM in cotton fabric?

GSM is short for grams per square meter. All fabrics have a weight, and the standard measurement for the weight and quality of fabrics i.e. grams per square meter. This number refers to the density of the fabric.

Which of the following indicates the GSM of the fabric?

GSM stands for grams per square meter, and is a standard measurement for fabric weight. The cutter allows us to cut out a perfect circle with an area of 100 cm, and the scale precisely measures the weight of the little fabric circle. We can then multiply that number by 100 to get the GSM of the fabric.
