THE STRUCTURE OF TEXTILE FIBRES IV--THE STRUCTURE OF COTTON.

This article discusses the structure of cotton fibers. It is noted that the length of the cotton fiber, its fineness, its convolutions, the shape of its cross-section, the thickness, and fibrillar construction of its walls are all details of the morphology of the fiber. The real existence of a molecular structure is imposed by a study of the chemical behavior of fibers. Between the morphological and the molecular, a third structure is recognized in which a patter is produced by a certain orderliness in the arrangement of neighboring macromolecules.
