Abstract
The intrinsically high internal mobility found in cotton fibers in their botanical growth state can be preserved by preventing the irreversible hydrogen bonding that normally occurs during first drying. Water transport, morphological, and mechanical data are presented to illustrate two examples of the permanent fixation of never-dried cotton, which has been shown in an earlier publication to be highly crystalline. In one, an acidic solution of formaldehyde is suggested to cause intrafibrillar cross-linking; in another mutual irradiation with acrylamide is known to cause grafting to the cellulose molecule. Both treatments effectively block the hydrogen bonding reaction by attachment of foreign groups to the cellulose fibrils.
