Abstract

Rayon fiber as clothing material has silk-like property which relates to other synthetic fibers. It has many advantages that is required to women's clothes. However rayon has many shortcomings. Therefore this research is to spin rayon-like polyester which has high contraction property to be synthesized by previous research to solve those shortcomings and to maintain advantages of rayon. The contraction ratio of regular polyester is 30% and the contraction ratio of this synthesized polyester is over 60%. The spinning temperature of regular polyester ranges from $285^{\circ}C$ to $300^{\circ}C$. However, this copolymer is set range from $270^{\circ}C$ to $290^{\circ}C$, which is $10^{\circ}C$ less than regular polyester due to decreasing melting temperature. The spinning velocity effects the tensile strength and elongation of yarn magnificently. The high velocity of spinning makes yarn highly oriented, increases the tensile strength and decreases the elongation. This research defines the condition as following; draw ratio 2.734, First roller temperature $85^{\circ}C$, Slit heater temperature $175^{\circ}C$.
