Abstract (en)
[origin: EP3719183A1] In this polyester multifilament, a core-component high-viscosity polyester and sheath-component low-viscosity polyester have been composited into a core-in-sheath, wherein the difference in intrinsic viscosity between the core component and the sheath component is 0.20 to 1.00, the total fineness is 4 to 30 dtex, the single-yarn fineness is 1.0 to 5.0 dtex; the breaking strength is 5.0 to 9.0 cN/dtex, the fracture elongation is 12 to 45%, the degree of interlacement is 2.0 to 15.0/m, and the number of filaments thereof is 3 to 15. This fine-denier polyester multifilament has high strength and excellent wear resistance and convergence, and makes it possible to obtain a high-density thin woven fabric suitable for use with athletic and outdoor clothing by combining excellent durability, weaving properties, and fabric grade.
