Abstract

A cotton yarn was immersed in aqueous solution of N-methylmorpholin N-oxide(NMMO) with various concentrations, and dried at 9$0^{\circ}C$ for various periods of time under constant-length condition, and investigated in relation to an effect of linenlike finishing. The solvent bonding between fibers of sample yarn is achieved by NMMO solution, and its tendency is increased with concentration of the solution. The stiffness is therefore increased with the concentration, which produce linenlike effect on the cotton yam. The period of drying time has positive effects on the stiffness, but much less than the concentration of solution. The tensile strength is increased in similar tendency of stiffness, and elongation is decreased a little. The tensile behavior for the samples treated with the solutions of 30% or higher concentration presents the initial elastic region, and its modulus and yield strength are roughly increased a little with the concentration of solution. The moisture regain and dye uptake are roughly increased with the concentration because of the mecerization-like effect by swelling of fiber with the NMMO.
