Elastic islands-in-a-sea fiber, a kind of polyester, was studied as fiber material for artificial suede. The elastic islands-in-a-sea fiber consisted of two polymers ; Sea component was cation dyeable polyester(CDP) and island component was polyetherester(PEE). PEE microfibers of 0.2 denier wee left when the sea component was dissolved with alkali in the suede finishing process. Optimum condition to produce this fiber was as follows; Spinning temperature of PEE was 25$0^{\circ}C$, that of CDP was 2$65^{\circ}C$, composition of CDP/PEE was 35/65, and the spinning speed was 700m/min.

Poly(ethylene terephthalate) fiber was pretreated with biphenyl/methylene chloride and other solutions. Other solutions used in this experiment were methylene chloride, perchloroethylene/methylene chloride, biphenyl/water and hiphenyl/perchloroethylene. The dyeing behaviors of the pretreated fibers with C.I. Disperse Red 4 in water were studied with reference to changes in the matter properties of fiber. Also density and X-ray diffraction of the fibers were investigated as measure of crystalline region. The results obtained are briefly discussed in terms of the plasticization of the fiber structure and penetraing biphenyl volume formed during the pretreatment and pretreated time and temperature. The results are as follows; 1) The crystalline growth of PET fiber treated with 5% biphenyl/methylene chloride was also greater than that treated with other solutions, and this tendency was increase with volume of added biphenyl. 2) Equilibrium dye absorption and initial rate of dyeing of PET fiber treated with 5% biphenyl/methylene chloride were greater than those of sample with other solution. 3) The diffusion and dye affinity of PET fiber treated with 5% biphenyl/methylene chloride were greater than those of sample with other solution. I think that dyeing method of energy conservation of pretreated PET fiber is dyeing PET fiber pretreated with 5% hiphenyl/methylene chloride.

In order to investigate the low liquor ratio dyeing method of poly(ethylene tereqphthalte)(PET) fiber, a basic study on two phase dyeing method was studied. The results are as follows; 1. Toluene, xylene, perchloroethylene, tetrachloroethane, and monochlorobenzene are effective as solvent, being considered their boiling points, solubilities in water, and the solubility of dye. 2. Dye partition quantity from solvents to water was proportional to the dissolved quantity of dye in solvents. 3. The crystallinity change of PET fiber dyed by two phase dyeing method had little difference from that of fiber dyed in water. 4. Initial dyeing rate of two phase dyeing method was greater than that of dyeing in water, and the solubility of dye in solvents had much influence on initial dyeing rate, but bath ratio had little. 5. Polymer coagulant was effective to the purification of dyeing waste-water. It was much easier because there was no auxiliaries in the two phase dyeing bath.
