Dyeing of Cotton/Polyester Blends with Disperse Dyes in the Presence of DMDHEU/PEG
DMDHEU/PEG와 분산염료를 이용한 면/폴리에스테르 혼방직물의 염색
Abstract
Cotton differs from polyester in physical and chemical properties. When cotton/polyester blends are dyed, water-soluble dyes are generally used for cotton and disperse dye for polyester. Thus, two bath or one bath-two step dyeing process are usually accepted. These processes consume more energy and cost compared to a single step process. To save energy and cost, a single step dyeing and finishing is carried out with disperse dyes in the presence of a crossslinking agent. K/S values of the dyed fabrics were determined to examine the dyeing property of cotton, cotton/polyester, polyester fabrics dyed with disperse dyes in the presence of DMDHEU/PEG. The concentration of DMDHEU, molecular weight and concentration of PEG, curing time and curing temperature were varied.
