Abstract
Fiber fineness, as measured by the Micronaire, and prior treatments have been found to be important factors in determining the rate and extent of cyanoethylation of cotton. Fineness was found to be a good index of the rate of reaction for both raw and pressure- boiled cotton fibers. Prior treatment of yarn by ethanol extraction, pressure boiling with 2% caustic ethanolamine extraction, and mercerization—both slack and at constant length—affected the rate of cyanoethylation and the rot resistance of the product.
