Composition test
Cotton & Others (blende) Fabric:
Necessary Tools:
a. A test specimen.
b. A biker and glass rod/stick.
c. Sulfuric acid-98%.
Process:
1) Cut a specimen than keep in dryer for remove humidity and then weighted it in 30Sec. Such as: 10 gm.
2) Make a solution [Acid: Water=7/6:3/4].Wait until cold. Than fabric keep in the solution and handle by glass rod about in 50/60 second cotton part will be burned.
3) Sample will be Washed off than dry it in dryer and measure the sample weight in 30 Second. Such as: 8gm.
Calculation :
{(Before weight-After weight) / Before weight} * 100 = Cotton %
{(10-8)/10}*100=20% Cotton.
Lycra & Others Fabric:
Necessary Tools:
a. A test specimen.
b. A gyro wash machine.
Process:
1) Cut a specimen than keep in dryer for remove humidity and then weighted it in 30Sec. Such as: 10 gm.
2) Sample keep in gyro wash pot than take N.N- Dimethylformamide.[M:L=1:20/30].
3) Than it will be run about 30/40Min at 95/1000 C Temperature.
4) Sample will be Washed off than dry it in dryer and measure the sample weight in 30 Second. Such as: 8gm.
Calculation :
{(Before weight-After weight) / Before weight} * 100 = Lycra %
{(10-8)/10}*100=20% Lycra.
