cotton bolls were harvested at three stages before boll opening (closed bolls), and after opening on the plant (field-opened bolls) half of the closed bolls were maintained in the never-dried state; the remaining closed bolls were allowed to air-dry and open off the plant. never-dried closed-boll fibers, rewet dried closed-boll fibers, and rewet field-opened fibers were treated with naoh solution and propylene oxide and spun into yarns. water retention, moisture vapor sorption, and dye uptake were greatly increased (relative to untreated dried cotton) by the treatment, but not to the level found for untreated never-dried cotton. fiber-bundle elongation and tenacity and yarn elongation were increased by the treatment; yarn tenacity was slightly decreased. 14 refs
