Abstract
The effect of laundering, mercerizing, and simulated vat dyeing on the properties of partially cyanoethylated cotton was investigated. Cotton sheeting cyanoethylated to various nitrogen contents, from 2.2 to 6.4%, was subjected to laundering, mercerizing, or simulated vat dyeing. The samples were then analyzed for thread count, weight, and thickness and tested for breaking strength, elongation, tearing strength, abrasion resistance, air permeability, stiffness, moisture regain, heat resistance, and rot resistance. In addition, wrinkle recovery of the partially cyanoethylated and untreated cloth was determined.
Results of the study indicate that neither laundering, mercerizing, nor simulated vat dyeing seriously affects the usual textile properties of partially cyanoethylated cotton. The rot resistance and heat resistance of samples of more than 4% nitrogen content were not greatly impaired by these treatments; however, a sample of 3.2% N was not rot- resistant after these subsequent treatments.
