TEAR STRENGTH TEST
The property of paper or fabric that is measured by the force required to tear it.
Apparatus used – “Elemendo of” Tear Strength Tester Maximum Capacity 6400 Gms.
Sample Size – Cut both warp and weft wise of size approximately 4”X3”.
Readings
Observation no. | Weft Wise |
1. | 23% of 6400 gms |
2. | 23% of 6400 gms |
3. | 23% of 6400 gms |
Average = 23% of 6400 gms
Observation no. | Warp Wise |
1. | 32% of 6400 gms |
2. | 32% of 6400 gms |
3. | 32% of 6400 gms |
Average= 32% of 6400 gms

COLOURFASTNESS TO WASHING
Colourfastness to washing is the ability of fabric to retain the dyes used to colour them when washed.
Apparatus used - Laundrometer
Grey scale
Sample size – 10cm X 10cm (Main Fabric)
10cm X 10cm (Bleached Fabric X 2)
Readings
Weight of Swatch = 1.4 gm
Solution Required = 70 gm
Greyscale reading and Bleached fabric = 4/5
Result
Based on the result of the colourfastness test, we can say that the fabric almost completely retained the dye when washed.

COLOURFASTNESS TO CROCKING
Crocking is the process of transfer of colour from the surface of coloured textile material to other surface by rubbing.
Apparatus used – Crockmeter
Sample Size – 8” X 3” (Main Fabric)
2” X 2” (Bleached White Fabric)
For both dry and wet test
Readings –
Observation no. | Grey Scale Reading (Dry) | Grey Scale Reading (Wet) |
1. | 4 | 3 |
2. | 4 | 3 |
Results –
Fabric is resistant to high level in dry state and leaves no colour in dry state, whereas in wet condition, the fabric leaves very little colour and is low resistant to colourfastness in wet state.

YARN COUNT TEST
To determine the count of yarn using Beesley Balance.
Apparatus used – “Beesley Balance”
Sample Size – Swatches of size = 10cm X 10cm
Readings –
Observation no. | Warp | Weft |
1. | 80 | 75 |
2. | 79 | 76 |
3. | 80 | 76 |
Average – Warp = 80
Weft = 76

TENSILE STRENGTH TEST
Tensile Strength is the maximum stress that a material can withstand which being stretched or pulled before failing or breaking.
Apparatus used – “Ramp” Tensile Strength Tester
Sample Size- 8” X 2” (Warp X Weft)
Readings –
Observation no. | Load (in N) | Distance (in mm) |
1. | 12.5 | 19 |
2. | 27.6 | 19 |
3. | 11.5 | 20 |
Average: - Load = 17.2 N
Distance = 19 mm

GSM TEST
GSM Test is the metric measurement of the weight of the fabric
Apparatus used – Fuji Electric Precision Balance
Sample Size- 3 samples of size 10cm X 10cm
Readings –
Observation no. | Readings (in gms) |
1. | 89.6 |
2. | 90.2 |
3. | 88.6 |
Average = 89.4 gms

BURN TEST
Burn Test is one of the most accepted methods for identifying the true nature of fabric. This test is carried out to know whether a fabric is made up of a natural fibre, man-made fibre or a blend.
Sample Size- 8cm X 5cm
