Hello

I want to know if I buy a t-shirt,there is write 100% is cotton,, but is there any method I can check it ?how can I prove the raw material in label is real?

Thanks

There are strict laws against labeling a garment 100% cotton and using other fibers. But then out prisons are overflowing wit law breakers.

I am not sure how you might tell the difference. Perhaps you could try a surface type microscope such as Radio shack 63-851. The cotton fibers might look different from any synthetic ones. You could compare an all cotton shirt with a poly blend and see if you can see any difference. Nobody likes to be hoodwinked.

Personally, I prefer the blends. A little polyester gives longer wear while keeping the good feel of the cotton.
