Note: Identification of fiber content is not achievable by a single image alone, It is essential to look at the accumulation of evidence provided by a series of images , each employing different microscopic techniques. The following set of images also shows the use of microsolubility as a confirmatory test.

Comments Fibers were treated with acetone, but did NOT dissolve, therefore shown to be rayon, not acetate.
Note although a single fiber appears with a twisting cross section typical of cotton, this is the only cotton which was found in the specimens examined. Presence of a single fiber of cotton is insufficient to support identification of cotton as a component of this fabric, since cotton is ubiquitous.
