To analyze the given Plain fabric sample.
NAME: To analyze the given Plain fabric sample.
To find weave, warp count, weft count, EPI, PPI.
Warp crimp & weft crimp% GSM, Denting
INSTRUMENTS: Beasley balance, crimp tester, fabric sample, picks glass etc.
Theory:
In plain weave the thread interlace in alternate order and weft thread are balanced that is similar in thickness and no, per unit area space two sense of threads bends about equality.
The weave is used for structure which range from very heavy and coarser blankets
OBSERVATION TABLE:
| SR NO | EPI | PPI | WARP COUNT | WEFT COUNT | WARP CRIMP% | WEFT CRIMP % |
| 1 | 39 | 35 | 8.91 | 9.64 | 4.76 | 1.96 |
| 2 | 38 | 33 | 8.90 | 9.65 | 4.00 | 2.00 |
| 3 | 39 | 34 | 8.89 | 9.67 | 4.50 | 2.02 |
| 4 | 38 | 35 | 8.88 | 9.61 | 4.36 | 1.89 |
| 5 | 40 | 35 | 8.92 | 9.65 | 4.42 | 1.43 |
| Mean | 38.8 | 34.4 | 8.90 | 9.64 | 4.40 | 1.86 |
Calculation:
1.Warp count NE= 1.091*0.453/840*0.066
= 8.91 Ne
2.Weft count Ne=1.091*0.453/840*0.061
= 9.64 Ne
3. Crimp %=Extended length-original length/original length*100
Warp crimp% =10.5-10/10 *100 =4.76
Weft crimp%=10.2-10/10 *100 =1.96 %
4.GSM = (Weight of sample/25 *10,000
= 0.468/25 *10000
= 180 g/m²
5.Denting =EPI=39/2=19.5 = 20%
6.Reed Count=20/2 =10 Ne.
Result:
The Following Results are found from the above Experiment.
EPI =38.8=39
PPI=34.4 =35
Warp crimp%= 4.40%
GSM= 180 g/m²
Warp count = 8.90
Weft count = 9.64
Weft crimp%=1.86
Denting = 105 NE
