Embodiment 1

[0026] The PET melt is extruded into bundles through the 48-hole three-lobed special-shaped spinneret holes, cooled, oiled and wound to obtain fine-denier triangular super-luster FDY polyester filaments. Among them, when the melt intrinsic viscosity is 0.630dl / g, the spinning temperature is 295°C, the spinning speed is 3800m / min, the side blowing wind speed is 0.3m / s, and the wind temperature is 26°C, 33dtex / 48f (single fiber fiber degree 0.69dtex), the breaking strength is 3.8cN / dtex, the elongation at break is 34%, and the Uster value is 0.8% fine denier triangular super bright FDY polyester filament. The fine denier triangular super-bright polyester filament has super bright luster and good hand feeling.

Embodiment 2

[0028] The PET melt is extruded into bundles through 36-hole three-lobe spinneret holes, cooled, oiled, clustered and oiled, and wound to obtain fine-denier triangular super-luster FDY polyester filaments. Among them, when the intrinsic viscosity of the melt is 0.640dl / g, the spinning temperature is 285°C, the spinning speed is 4000m / min, the side blowing wind speed is 0.4m / s, and the wind temperature is 24°C, the obtained 22dtex / 36f (single fiber fiber 0.61dtex), the breaking strength is 4.0cN / dtex, the elongation at break is 33%, and the Uster value is 1.0% fine denier triangular super bright FDY polyester filament. The fine denier triangular super-bright polyester filament has super bright luster and good hand feeling.

Embodiment 3

[0030] The PET melt is extruded into bundles through the 72-hole three-lobe special-shaped spinneret hole, cooled, bundled and oiled, and wound to obtain fine denier triangular super-luster FDY polyester filaments. Among them, when the intrinsic viscosity of the melt is 0.635dl / g, the spinning temperature is 290°C, the spinning speed is 4300m / min, the cooling wind speed is 0.5m / s, and the wind temperature is 23°C, 22dtex / 72f (single fiber degree 0.30dtex), the breaking strength is 4.4cN / dtex, the elongation at break is 30%, and the Uster value is 1.2% fine denier triangle super bright FDY polyester filament. The fine denier triangular super-bright polyester filament has super bright luster and good hand feeling.

Abstract

The invention discloses a terylene fine denier triangular super-glossy FDY filament and relevant preparation method, and belongs to the technical field of terylene fibers. During the course of filature preparation, the invented fine denier triangular super-glossy terylene filament can lower filature speed, shorten calm zone distance and milden air blow cooling conditions; meanwhile, the fiber adopts nozzle oiling mode to improve oiling position, in order to successfully prepare fine denier triangular super-glossy FDY terylene filament with denier no more than 0.7dtex, fiber corss section similar to regular triangle and super-bright glossy. The terylene filament has advantages of extremely perfect flexibleness, excellent hand feeling, and moreover, the product is characterized by fewer broken filament, fewer short ends, more uniform yarn more stable quality.

Description

technical field [0001] The invention relates to a fine-denier triangular super-bright polyester filament and a preparation method thereof. Background technique [0002] With people's urgent demand for high-grade and comfortable clothing fabrics, the market demand for glossy fine-denier polyester filaments is increasing because of their comfort and fashion, good luster and sense, and good hand feeling. However, the glossy polyester filaments currently produced are poor in comfort and softness, the outer surface of the filaments has poor refraction and reflection effects on light, the luster is dull, and there are many hairs, which are easy to break, and the woven fabrics lack softness and brightness. . [0003] In order to obtain a brighter luster, it is generally achieved by adding some additives or shaping the fiber cross section. Additives are barium sulfate (BaSO 4 ), calcium carbonate (CaCO 3 ), silicon dioxide (SiO 2 ) etc., Chinese Patent Application No. 200310105...
