Abstract (en)
[origin: WO0244447A1] The present invention relates to a sea-island type composite fiber and process of preparing the same. In accordance with the present invention, a sea-island type composite fiber for a raised warp knit fabric which is prepared by the direct spin draw method by using alkali soluble copolymer polyester as a sea component and polyester mainly consisting of polyethylene terephthalate of more than 90 mole% as an island component, wherein the composite fiber is characterized in that it satisfies the following thermal properties and viscoelastic properties: - a number of presence of melting point peaks: 4, - a temperature of main melting point peak of sea component [Tms]: 220 SIMILAR 235 DEG C, - a temperature of main melting point peak of island component [Tmi]: 245 SIMILAR 255 DEG C, - a first transition peak temperature [T alpha ] of viscoelastic index (tan delta ): 120 SIMILAR 150 DEG C and - a viscoelastic index value [tan delta alpha ] of the first transition peak ( delta -peak): 0.10 SIMILAR 0.20. The sea-island type composite fiber prepared by the present invention has good thermal shrinkage properties and excellent raising property and improves the appearance and touch of warp knit.
