(a) An idealized cross-section of the cotton hair. The domino-like blocks shownin cross-section are arranged according to Balls conception. (b) The spiral arrangement of these domino-like blocks or fibrils is shown,together with the separating pits in the wall, and the slip-spiral effect along the fibrils. Obviously these conventional type figures do not represent the true shape of thecotton of commerce, but they approximate the sha

Obviously these conventional type figures do not represent the true shape of thecotton of commerce, but they approximate the shape during the growth period,before the boll is opened. As the hair dries out, the central lumen collapses and thehair twists. MOISTURE IN TEXTILES 235 caustic soda can a differentiation be detected in the cross-sectionalstructure of the fiber to indicate this growth-ring character. Thusthe fibrils are considered as being separated by air spaces on all sides,the whole cotton hair is spongy, and the surfaces of cellulose boundingthese air spaces are in
