Example Embodiment

[0016] Example 1

[0017] A preparation method of polyester high-F fine denier wool-like fiber, comprising the following steps:

[0018] The first step, selection of raw materials: purified terephthalic acid and PET polyester melt obtained by chemical reaction of PTA, ethylene glycol and catalyst, and the viscosity of PET polyester melt is 0.635~0.65dl / g;

[0019] The second step, production process: through booster pump→melt distribution valve→spinning box→metering pump melt extrusion→spinning assembly→cooling and forming→oiling nozzle→spinning tunnel→pre-network→GR1 guide wire Reel → GR2 godet → automatic winding → mechanical doffing → quality inspection to prepare a polyester high F fine denier wool-like fiber with a monofilament linear density of 0.97dtex; the PET polyester melt is passed through a booster pump. It is delivered to the melt distribution valve at a flow rate of 170~185T; the spinneret holes on the spinneret are evenly distributed in a concentric radial patt...

Abstract

The invention discloses a method for preparing polyester high-F fine-denier wool-like fibers. The method includes the following steps that raw materials including purified terephthalic acid and PET polyester melt are selected; secondly, according to the production process, the raw materials pass a booster pump, a melt distribution valve and a spinning box, the melt is extruded by a metering pump, a spinning assembly is used, cooling and forming are conducted, an oil nozzle is oiled, a spinning channel is used, pre-interlacing is conducted, a GR1 draw-off godet and a GR2 draw-off godet are used, full-automatic winding is conducted, mechanical doffing is conducted, and quality testing is conducted; thirdly, the product is packaged on an assembly line, wherein the prepared polyester high-F fine-denier wool-like fibers are packaged through the assembly line. The method for preparing the polyester high-F fine-denier wool-like fibers changes the aperture and the distribution mode of spinneret orifices on an original spinneret plate, spinnability of the fibers is improved, production is stabilized, a foundation is laid for further optimizing the process and product quality, meanwhile the F number of the fibers is increased, velvet feeling of the fibers is improved, and the wool-like effect is achieved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of polyester filament production, in particular to a method for preparing polyester high-F fine-denier wool-like fibers. [0003] Background technique: [0004] With the restart of the Silk Road, the differential technology of polyester fiber will definitely be the focus of chemical fiber enterprises. The term differential fiber originated from Japan in the early years. fiber. Differentiated fibers mainly focus on improving the performance of fabrics, preferring clothing and decorative fabrics, and with the continuous changes in people's consumption concepts, the pursuit of comfort, high-end, health care, and nature has become a new fashion, and the pursuit of clothing has become diversified. , Functionalization, making some novel differentiated fibers popular. [0005] With the promotion of differentiated production technology of polyester fiber in recent years, it is difficult for ordinary convent...
