Diester형 분산염료란 염료 분자 구조 중에 diester기를 함유하고 있어 염색은 일반 분산염료와 동일하게 수행하고, 염색 후 묽은 알칼리 용액으로 처리하면 섬유 표면에 존재하는 미고착 염료들의 ester기가 가수분해되어 sodium carboxylate가 생성되면서 염료가 수용성으로 변하여 쉽게 제거되는 성질을 가진 염료를 말한다. (중략)

The aim of this study is to find the optimal combination dyeing condition for the enhancement of dye uptake and union dyeing of the composite material fabric made of triacetate and quick drying PET blended yarn. For the experiment, fabrics were one-bath combination dyed using the mixed dye of E-type disperse dye(C.I Disperse red 50) and S-type disperse dye(C.I. Disperse red 92) to measure dyed fabric's dye exhaustion, dye uptake, color and color difference according to the diverse conditions including dying temperature, time and mixed ratio of the dye. Dye equilibrium of combination dyeing occurred in $100^{\circ}C$, but by comparing dyed fabrics' K/S value and surface color, it was found that $120^{\circ}C$ was where the manifestation of color of triacetate and quick drying PET was identical. Mixed dye exhaustion and dye uptake merely changed as dyeing time increased, but color became more uniform. Therefore, it can be concluded that by using combination dyeing method, and by using the mixed dye which the mixing ratio of S-type dye and E-type dye is appropriately controlled, dye uptake can be improved compared to using single dyeing regardless of the color of E-type dye.
