Here, both the empirical and experimental data were compared with each other to verify through an equation where if the stitch length and count increases then the GSM decreases. This is due to the relation among GSM, count and stitch length; where GSM is inversely proportional to the count and stitch length.
How do you calculate GSM in knitting fabric?
– Cut 5 swatches from the different place of the fabric. – Weight all test swatches accurately and calculate average weight of swatches. – Multiply the average weight of swatches by 100 to calculate GSM of the sample fabric. (Normally, the area of round GSM cutter is 1/100 square meters.)
How do you find the GSM of yarn?
To show the right method for GSM calculation, I have presented here an easy method for you, it will be very effective for all.
- Warp count- 50.
- Weft count- 40.
- EPI (Ends per inch) – 130.
- PPI (Picks per inch) – 60.
- Warp crimp factor- 1.2.
- Weft crimp factor- 1.0.
How do you find the density of a stitch?
Stitch density is the number of stitches per unit area, obtained by multiplying the number of courses per inch (25 mm) by the number of wales per inch (25 mm).
How do you count yarn in knitting fabric?
The direct system is calculated with the formula N = (W/l) / (L/w). The indirect system uses the formula: N = (L/w) / (W/l). In these formulas, N is the yarn count, W is the weight of a sample of yarn, l is the unit of length, L is the length of the sample, and w is the unit of weight.
How do you convert weight to GSM?
Multiply each pound of text paper by 1.48. 1 lb. of Cover paper = 2.708 gsm. Multiply each pound of cover paper by 2.708.
How do you convert basis weight to GSM?
To convert basis weight of a given standard size of paper to grams per square meter, multiply its basis weight by 1406.5 and divide the results by the square area of its basic size.
How do you convert from GSM to meters?
In the example:
- Fabric length is 1700 meters.
- Fabric width = 72 inch convert it into meters = (72 * 2.54) /100 =1.83 meters.
- Fabric GSM = 230 grams.
What is GSM material?
GSM stands for Grams per Square Metre and it is the metric measurement to check the weight of the fabric. GSM value is dependent on the kind of fabric – Cotton, wool, polyester etc. The fabric GSM is directly proportional to the thickness of the fabric. As the value of gsm increases, the thickness increases as well.
What is stitch length?
Stitch length is basically how long each stitch is sewn by your sewing machine. Changing the stitch length adjusts the feed dogs, which controls how much fabric is pulled through with each stitch. For a shorter length, less fabric is pulled through. For a longer stitch, more fabric is pulled through.
What is stitch density?
Density is the distance between individual stitches in a satin column or rows of stitches in a fill. The closer the rows are to each other, the more dense an area of stitches is.
What is a knitting loop called?
In weaving, threads are always straight, running parallel either lengthwise (warp threads) or crosswise (weft threads). By contrast, the yarn in knitted fabrics follows a meandering path (a course), forming symmetric loops (also called bights) symmetrically above and below the mean path of the yarn.
How do you measure thread count on fabric?
It is measured by counting the number of threads contained in one square inch of fabric or one square centimeter, including both the length warp and width weft threads. For example, if there are 100 threads per inch horizontally and 100 lengthwise, the fabric will have a thread count of 200.
What is yarn count in fabric?
Yarn count refers to the thickness of a yarn and is determined by its mass per unit length. It is usually measured by the number of grams per one kilometer of yarn, a unit of measure called “Tex”.
How do you calculate weight from yarn length?
How much yarn do you have?
- Multiply the number of yards or meters in a full skein (on the yarn’s label) by the weight of the partial skein (use a scale to measure this).
- Take that number and divide it by the weight of the full skein (on the yarn’s label).
