The Bleached and Unbleached cotton differ chemicallyas :

[A] Bleeching removes the natural COTTON OILS from the fibres.

[B]The % transmission(280-380nm) of the Unbleached cotton varies from 20-30% while that of Bleached cotton is only 20%.

The attached file shows a graph between variation of % transmission of the Unbleached and Bleached cotton vs the wave length.

Yes; it looks .
