Comparison study in nonformaldehyde durable press finishing of framie and cotton with glyoxal and polyethylene glycol

摘要

A comparative study was made in nonformaldehyde durable press (DP) finish of ramie and cotton, in the presence of glyoxal and polyethylene glycol (PEG). The wrinkle recovery angle (WRA) of the treated cotton was generally higher than that of ramie, but reduction in strength was greater in ramie than in cotton, due to the stiff nature of ramie. Water of imbibition (WIM) and moisture regain (MR) of the treated ramie and cotton were similar, but the whiteness index (WI) of cotton was higher than that of ramie. In general, WRA, retention of strength, softness. WIM, MR, K/S values with direct dyes and WI of the treated ramie and cotton were signficantly enhanced with increase in molecular weight of PEG and PEG600 concentration. Noformaldehyde DP finishing of ramie and cotton is, therefore, feasible with glyoxal in the presence of PEG.
