Terylene fine-denier triangle super bright FDY filament and preparation method thereof

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...
