Embodiment 1

[0063] A colored special-shaped ultrafine denier polyester monofilament, the mass percentage of its raw material is:

[0064]

[0065] The preparation method of described antiaging capsule, its concrete steps are:

[0066] (a) preparation of p-dihydroxy p-phenol phosphine

[0067] Using phenylphosphine and paraformaldehyde as raw materials, using a mixed solution of water and isopropanol as a solvent, an affinity addition reaction occurs under the action of a catalyst, the reaction temperature is controlled at 35-50°C, and the reaction time is 3-4 hours; preparation Dihydroxymethylphenylphosphine is obtained, and then at 85-95°C, a mixed solution of hydrogen peroxide and concentrated sulfuric acid is added as a strong oxidant, and the oxidation is performed for 45-60 minutes to prepare dimethylolphenylphosphine oxide. Add p-dihydroxyphenylphosphine, bromine water and iron powder into the reaction vessel, heat to 65-75°C and react for 0.5-1.75 hours, then filter to obtain a...

Abstract

The invention relates to colored special-shaped super fine denier polyester monofilaments and a production method thereof. The colored special-shaped super fine denier polyester monofilaments are prepared from, by mass, 1-5% of anti-aging capsules, 5-10% of pigment, 5-10% of PEN slices, 1-3% of a dispersing agent and the balance polyester slices. The PEN slices, the polyester slices, the anti-aging capsules, the pigment and the dispersing agent are extruded and mixed together through a screw machine and then melted, melt is prepared and subjected to melt spinning through a special-shaped spinneret plate, and the colored special-shaped super fine denier polyester monofilaments are obtained. Due to the fact that PEN is added, the heat resistance of fibers is improved, and thus the roll sticking phenomenon is avoided when the heat setting temperature is higher than 245 DEG C; meanwhile, due to the higher heat setting temperature, disorientation of an orientation structure of an amorphous area is accelerated, the internal stress of the fibers is reduced, and thus the dimension stability of the fibers is improved; the setting temperature is raised, the mobility of macromolecular chains in the fiber structure is enhanced, the degree of crystallinity is increased, the content of an amorphous area is reduced, and the boiling water shrinkage is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of polyester monofilament, in particular to a colored special-shaped ultrafine denier polyester monofilament and a production method thereof. 【Background technique】 [0002] Chinese Patent Application No. 200910027027.9 relates to a melt direct spinning ultrafine denier polyester FDY yarn and its preparation process. The ultrafine denier polyester FDY yarn is produced according to the melt direct spinning one-step method, and the diameter of the pores used is 0.15-0.2MM. L / D=2.6-3.6, the spinneret with a plate surface diameter of 70-90MM, a fairing installed in the fiber cooling area and a two-way oiling system to directly produce ultra-fine FDY filaments, and the obtained single filament fineness DPF is 0.3-0.6, one The number of beam holes is 144F-192F; the process route adopted can greatly reduce the processing cost while improving the internal quality of the product, and has the ability to replace impo...
