  • The effects of DP finishing conditions including process technique and finishing agent on the mechanical properties and hand of cotton fabrics were investigated. 100% cotton fabrics were treated with NMA/DMDHEU and NMA/YF using wet-fixation and steam-fixation process. For comparison, conventional pad-dry-cure process was used with DMDHEU. After DP finishing, tensile and compressional resilience increased and bending hysteresis decreased, resulting in the improvement of dimensional stability of cotton fabric. WF and SF process rendered fabrics better shear properties, tensile energy, and compressional linearity and energy than PDC process. However, SF process produced fabrics with higher geometrical roughness than WF process. After DP finishing, primary hand values except Koshi increased, resulting in the increase of total hand value of cotton fabric.

  • The factors which affect the absorption and diffusion of disperse dye in print paste for polyester film were investigated using film roll method. When Emvatex print paste of different disperse dye concentrations were fixed by high temperature steaming(HTS) for 2 hr at $190^{\circ}C$, the dye uptake and diffusion distance of 50g/kg dye concentration for PET film were very low, but those of 100$\sim$300g/kg were increased with increasing dye concentration. It was found that sodium alginate(5%) was more effective for the absorption and diffusion of disperse dye to PET film than CMC(3%) and Emvatex(18%), and Emvatex showed comparatively low absorption in three thickeners used. The dye uptake and diffusion distance of disperse dye in sodium alginate paste for PET film were increased with increasing paste thickness to $160\sim180{\mu}m$, but were decreased at $200\sim220{\mu}m$ in both fixations of baking and HTS for 2 hr at $190^{\circ}C$, and were far more largely increased by fixation of HTS than baking because steam was very important for fixation. Also it was confirmed that dye uptake was slightly increased as steam supply pressure was raised from 1 $kg/cm^2$ to 2 $kg/cm^2$, andthe dye uptake and diffusion distance of disperse dye were outstandingly increased with raising fixing temperature from $170^{\circ}C$ to $190^{\circ}C$ and fixing time from 0.5 hr to 3 hr in the fixation of HTS.
