Dyeing and fastness properties of direct spun type PET microfiber have been compared with those of regular PET fiber and PET-Nylon conjugated microfiber. The dye uptake of finer microfibers commenced at lower temperatures and showed faster rate of dye uptake. The build-up and wash fastness properties of disperse dyes on direct spun type PET microfiber were relatively better than split type PET-Nylon microfiber.

This study investigates the dyeability and the fastness of flame retardant polyester fabric developed by a thermal bonding with a low melting component of flame retardant bicomponent filament (LMFRPC). The fabrics were prepared with flame retardant polyester filaments (FRP) as warp and blended filaments of FRP and LMFRPC as weft. The LMFRPC have a sheath and a core where the core comprises a flame retardant polyester and the sheath comprises a thermoplastic polyester with a low-melting point. The thermal bonding of fabric was conducted in a pin tenter at $170^{\circ}C$ for 60 seconds. Fabric dyeing was conducted with an infrared dyeing machine at various dyeing temperatures and dyeing times. The dyestuffs used in this study were CI disperse Yellow 54, Red 60 and Blue 56 of E-type dyestuff and Orange 30, Red 167 and Blue 79 of S-type dyestuff. This study investigated the morphology of thermal bonded fabric, dyeability and fastness of dyed fabric. Dyeability increased with an increased dyeing temperature. The thermal bonded area increased with the increased LMFRPC content. The dyeability of S-type dyestuff was higher than E-type dyestuff; in addition, the saturated dyeing time was about 20minutes at $130^{\circ}C$ for E and S-type dyestuff. The fastness to washing and rubbing were excellent at a 4-5 Grade.

[ $TiO_2$ ] contents in yarns can influence color yield so that dyeing quality of industrial polyethylene terephthalate (PET) yarns can be improved through the adjustment of $TiO_2$ contents. To evaluate the dyeing performance of color yield, the chips which included the different $TiO_2$ contents of 330,550, and 1,100 ppm respectively were used to produce the yarns of different $TiO_2$ content by a spin-draft machine. The physical and structural properties of the yarns were measured to investigate effect of the $TiO_2$ contents on them. Dye uptake and dyeing rate were also evaluated using a colorimeter to compare the yarns having different TiOz contents. The experimental results showed that there were no appreciable variation in physical and structural properties among the yarn samples and no difference were observed among the dyed fabric samples with regard to dyeing uptake and dyeing rate. However, the color yield of dyed fabrics increased as $TiO_2$ contents decreased in the yarns especially when the fabric samples were dyed to pale shade. The physical reasoning could be proposed on why the yarns having low $TiO_2$ contents appeared to have higher color yield after dyeing.

The five new red disperse dyes for unmodified pure polypropylene fibers were synthesized. As a coupling component, a di-n-hexyl substituent was used in common, while various substituents were used for the diazo component. The dye having electron donating group at diazo component showed hypsochromic shift compared to the unsubstituted dye, while the dyes having electron withdrawing groups showed bathochromic shift. Owing to their extreme hydrophobicity caused by the di-n-hexyl substituent, all dyes exhibited very high affinity toward pure polypropylene fibers. Fastness to washing was very good for all dyes and fastness to light was good except two purplish red dyes.

In this study, we conducted alkali hydrolysis on sea-island type PET ultramicrofiber tricot fabric and dyeing according to the various conditions with black disperse dye. Herein, we evaluated the weight loss rate and tensile strength according to the NaOH contents. The optimal alkali hydrolysis treatment conditions were set to 25 %omf NaOH with a treatment time of 60 min at 110 ℃, and average weight loss rate of the PET ultramicrofiber tricot fabric is about 23 %. The dyeing conditions were investigated with different dyeing temperatures(95-135 ℃), dyeing time(20-60 min), dye contents(2-10 %omf), dispersant contents(1-9 g/ℓ), pH buffer solution contents(1-9 g/ℓ), UV-absorbent contents(5-25 %omf) and reduction cleaning process conditions for black color. We obtained the optimum conditions of the dyeing with the dye contents of 8 %omf, the dispersant contents of 1 g/ℓ, the pH buffer solution contents of 1 g/ℓ, the UV-absorbent contents of 10 %omf, the dyeing temperature of 135 ℃ and the dyeing time of 40 min. The light colorfastness of dyed ultramicrofiber PET tricot fabric was good to excellent in the range of 4 to 5.
