Embodiment 1

[0031] TiO in this example 2 The addition ratio is 2.8%.

[0032] The production process of superfine denier direct spinning full-dull polyester filament is characterized in that it comprises the following steps:

[0033] 1) Put the raw materials into the polymerization reaction device to generate polyester melt under the action of the catalyst, pass the full-dull polyester melt into the heat exchanger through the heat preservation pipeline for heat exchange, and then pressurize through the booster pump to achieve spinning The required pre-pump pressure;

[0034] 2) Insulate the pressurized full-dull polyester melt, and send it to the spinning box through the pipeline outside the box. The temperature of the spinning box is 290°C, metered by the spinning metering pump, and then passed through the box. The pipe distributes the full-dull polyester melt evenly into the spinning pack;

[0035] 3) The amount of full-dull polyester melt in the spinning assembly entering the metal ...

Embodiment 2

[0041] TiO in this embodiment 2 The addition ratio is 2.9%.

Abstract

The invention discloses a production technology for a superfine-denier direct-spinning complete-extinction polyester filament yarn. The specific raw material ratio is adopted, the raw material comprises polyethylene glycol terephthalate, cellulose acetate butyrate, wood fiber powder, titanium dioxide, vinyltriacetoxysilane, sulfuric acid, calcium nitrate, dimethylethanolamine, glyceryl tristearateand di-diisopropyl titanate, and through a series of technologies of polymerizing, pressurizing, spinning, oiling and post-treating, the polyester filament yarn is obtained; the polyester filament yarn is soft in hand feeling, mild in gloss and bright in color, the overhanging feel of a fabric is good, the polyester filament yarn can be widely applied in high-grade clothing and high-grade blankets, the TiO2 aggregation problem is solved, and the filament yarn has the good extinction effect and the good spinnability.

Description

technical field [0001] The invention belongs to the technical field of chemical fibers, and in particular relates to a production process of superfine denier direct-spun full-dull polyester filaments. Background technique [0002] The full-dull fabric developed from full-dull filament has soft handle, soft luster, bright colors, good fabric drape, and great market demand. People have higher pursuit to the functionality, handle and appearance style of polyester fiber, and all-dull polyester is also widely favored by people. Full matte products are popular because of their unique style. It is mainly manifested in soft luster, bright colors, and good drape of fabrics. Domestically developed full-dull varieties are mainly concentrated in viscose fiber and polyester staple fiber. The production and processing technology of polyester filament still needs to be perfected and improved. [0003] Due to the regular shape of conventional polyester, it has obvious reflection and flash...
