Embodiment 1

[0019] A kind of production method of light denier light flame retardant polyester FDY filament, it comprises the following steps:

[0020] (1) By weight, weigh 79% of the glossy PET chips to pre-crystallize and dry; by weight, weigh 6% of the black masterbatch and 8% of the flame-retardant masterbatch to dry, and weigh 6% of the crystallization accelerator , weigh 1% of electromagnetic stress particles;

[0021] (2) Mix the dried glossy PET chips with the dried black masterbatch and flame-retardant masterbatch, and then make a mixed PET melt through a screw extruder;

[0022] (3) After the mixed PET melt is filtered and pressurized, it is distributed to each spinneret assembly by a metering pump to produce nascent fibers;

[0023] (4) blowing and cooling the as-spun fibers in the spinning tunnel, the spinning tunnel is divided into upper and lower parts, the upper part of the spinning tunnel is blown with alkaline cooling air, and the lower part of the spinning tunnel is blo...

Embodiment 2

[0031] A kind of production method of light denier light flame retardant polyester FDY filament, it comprises the following steps:

[0032] (1) By weight, weigh 75% of the glossy PET chips for pre-crystallization and drying; by weight, weigh 7% of the black masterbatch and 8% of the flame retardant masterbatch to dry, and weigh 7% of the crystallization accelerator , weigh 3% of electromagnetic stress particles;

Abstract

The invention discloses a method for producing fine denier bright flame-retardant polyester FDY filament, and the method comprises the steps of (1) weighing 70%-80% bright PET slice, 6%-8% black master batch and 8%-10% flame-retardant master batch, 6%-10% crystallization-promoting agent, 1%-3% electromagnetic stress particles; (2) mixing the bright PET slice with the black master batch and the flame-retardant master batch to obtain a mixed PET melt; (3)filtering and pressurizing the mixed PET melt, and then distributing the melt to each filament-spraying assembly through a metering pump to generate nascent fiber; (4) blowing and cooling the nascent fiber in a spinning path; (5) applying a controllable pulse magnetic field in the PET melt fusion process, the nascent fiber cooling process and the process that the PET melt is sprayed from the filament-spraying assembly to form the nascent fiber; and (6) subjecting the cooled fiber to oil applying by an oil nozzle, stretching and shaping, gridding and winding successively.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, relates to a polyester FDY filament, in particular to a production method of a fine denier glossy ultra-black polyester FDY filament. Background technique [0002] Polyester fabrics are closely related to people's lives and are closely connected. They are used for clothing, bedding, decorations, bags, tents, etc. Polyester FDY (full name Fully Drawn Yarn, fully drawn yarn) introduces stretching in the spinning process, and can obtain winding yarn with high degree of orientation and medium crystallinity. Polyester FDY fabric feels smooth and soft, and is often used to weave imitation silk fabrics. The existing white polyester FDY filament cannot meet people's daily needs to a certain extent, so it needs to be improved. Extra black FDY filament is a special modified fiber, which is made by adding black masterbatch on the basis of the original FDY white silk, and processed through a certain...
