A Study on the Physical Properties & Dye Ability as Applying LMB & SMB with Luminent Yarn Manufacture - The Effects of Liquid Color and Disperse Dyes on the Phosphorescent PET Films -

Phosphorescent PET/liquid color films and phosphorescent PET/disperse dyes films were prepared by melt casting method using Hot press. Then, weight ratios and exhaustion percent of films were 0.7, 1.2, 1.5, 2.0, and 2.3 wt.%. The effects of L/C and D/D contents(wt.%) of films on the thermal properties, crystal structure, H(%), brightness$(mcd/mm^2)$, morphology, and tensile properties were investigated by means of DSC and WAXD, etc. It was found that the melting temperature and crystalline diffraction peaks were not changes with increasing the liquid color contents and disperse dyes exhaustion. Also, in case of using liquid color to phosphorescent PET film, the H(%) and brightness$(mcd/mm^2)$ value were superior to phos.PET/disperse dyes film. The tensile strength and the tensile modulus were decreased with increasing the contents of liquid color and exhaustion of disperse dyes in the phosphorescent PET film. Also, the elongation at break was increased with increasing the contents of liquid color and exhaustion of disperse dyes in the phosphorescent PET film.
