Example Embodiment

[0033] Example 1:

[0034]Take a variety of far-infrared inorganic materials whose basic ingredients are a mixture of silicon dioxide (28.5%), aluminum oxide (4%), titanium dioxide (61%), and zirconium dioxide (6.5%), and use an ultra-fine jet mill It is pulverized to a particle size of 0.45μm, and then placed in a high-temperature furnace for sintering at a temperature of 900°C, sintered and cooled, and then pulverized. The particle size is still controlled at 0.45μm to obtain a composite inorganic far-infrared ultrafine powder. Take 40 parts of the superfine powder, 3 parts of tris(dioctylpyrophosphate) titanate, 1 part of ethylene bisstearamide, and 56 parts of polyethylene terephthalate carrier. They are mixed together in a high-speed mixer, and the obtained mixed powder is sent to a twin-screw extruder for blending, extruding, and pelletizing. The specific masterbatch blending process is as follows:

Example Embodiment

[0041] Example 2:

[0042] The fiber of the present invention is made of polyethylene terephthalate melt containing about 4% far-infrared radiation additives, using 16 mesh aluminum oxide filter sand and 250 mesh wire mesh to filter the melt. Spinning at a winding speed of 1 minute, the post-draft is 3.033 times. Spinning was normal until 72 hours, and the obtained fiber was qualified.

Example Embodiment

[0043] Example 3:

[0044] The melt is filtered with 40 mesh sea sand and 250 mesh wire mesh, and it is spun and wound under the same conditions as above. The spinning was normal at 36 hours, and the obtained fiber was a qualified product.

Abstract

The invention relates to a far-infrared radiation hollow three-dimensional crimped polyester fiber in the fields of chemical engineering, polymer and chemical fiber manufacturing and a manufacturing method thereof, which combines 0.3-0.5 μm composite inorganic far-infrared ultrafine The coupling agent and surfactant are added into the high-speed mixer together for dry surface treatment. The superfine material powder after surface treatment is mixed with the polyester carrier in the high-speed mixer, and the mixed powder obtained is sent to the twin-screw extruder. Co-extrusion, its working temperature is 10-30°C lower than that of conventional color masterbatch. The far-infrared masterbatch and polyester chips obtained above are fed to the mixer through the metering feeder for mixing, and then sent to the production of hollow three-dimensional The crimped fiber is spun by a screw spinning machine, and the final product obtained is the far-infrared radiation hollow three-dimensional crimped polyester fiber of the present invention.

Description

[0001] Involved areas [0002] The invention relates to a far-infrared radiation hollow three-dimensional crimped polyester fiber in the fields of chemical engineering, polymer and chemical fiber manufacturing and a manufacturing method thereof. Background technique [0003] Generally, two methods are used to manufacture far-infrared textiles: one is to coat far-infrared materials on the surface of textiles; the other is to mix far-infrared materials into chemical fiber spinning solutions (including melt spinning and wet spinning) to make far-infrared fibers, and then Processed into far infrared textiles. The former is easy to process and saves far-infrared materials; the latter is washable and feels better. The strength of the heat preservation and health care function of infrared textiles is related to the formula, dosage, particle size, distribution in the fiber and the shape of the fiber fabric of the selected far-infrared material. The cross section of existing far-infr...
