Embodiment 1

[0019] (1) Add 27kg of dimethylformamide (hereinafter referred to as DMF) in a jacketed 50-liter dissolution kettle to pre-cool to 0°C, stir constantly, add 9kg of fully dry pure polyacrylonitrile powder, and add known Pigment, antistatic agent etc. (here not specifically limited), stirred for 8 hours. Then the temperature was raised to 75° C. and stirred for 6 hours to prepare a spinning slurry.

[0020] (2) Add 0.9kg egg white powder to the spinning slurry, stir evenly; filter with 200 mesh stainless steel wire mesh, vacuum defoam, and reserve; A spinneret with a nozzle diameter of 0.35 mm is extruded, and the extruded thin stream is formed into a wet monofilament bundle in a coagulation bath containing 60 wt% DMF aqueous solution at 15°C. ;

[0021] The wet tow is washed with water, stretched 6 times, relaxed and shrunk by 30% in hot air to obtain a dry tow.

[0022] The egg white powder is steamed for 1 hour, then baked in an oven at 120° C. for 1 hour, ground and sieve...

Embodiment 2

[0030] According to the spinning slurry obtained in the step (1) of Example 1, get 30kg of the spinning slurry, then add egg white powder 0.6kg and carbon black powder 0.06kg through steaming for 1 hour and drying at 120°C for 1 hour , all the other are processed and prepared by the steps (2), (3), (4) of Example 1 to obtain black artificial hair.

[0031] The monofilament fineness of black artificial hair thus made is 49dtex, the tensile strength is 3.2CN / dtex, the elongation is 31%, the luster is soft, there is no aurora, and the matting effect is achieved, and the simulation effect is increased.

Abstract

A preparation method of artificial sub-gloss high temperature resistant polyacrylonitrile hair concretely comprises the following steps: 1, adding pure polyacrylonitrile, or bipolymers or terpolymers containing below 15wt% of vinyl monomers to a spinning solvent, and simultaneously adding a widely-known pigment, an antistatic agent and the like to prepare a spinning slurry; 2, adding egg white powder accounting for 5-15wt% of the total solid content of the spinning slurry to the spinning slurry, uniformly stirring, and carrying out wet spinning to prepare filament bundles; 3, immersing the filament bundles prepared in step 2 in an aqueous solution of a chemical crosslinking agent; and 4, taking out the immersed filament bundles, washing with water, steaming, carrying out surface treatment, and drying to obtain the artificial sub-gloss high temperature resistant polyacrylonitrile hair.

Description

technical field [0001] The invention belongs to the field of artificial hair manufacture, and in particular relates to a matte high-temperature-resistant polyacrylonitrile artificial hair and a manufacturing method thereof. Background technique [0002] The wigs made of polyacrylonitrile artificial hair resemble real hair, which has the advantage of simulation, but the fly in the ointment is that the appearance is still too bright and not soft enough to meet the needs of consumers. Contents of the invention [0003] The object of the present invention is to provide a kind of matte high temperature resistant polyacrylonitrile artificial hair, which has soft luster, no aurora, and achieves matting effect. [0004] Another object of the present invention is to provide a method for preparing matte high temperature resistant polyacrylonitrile artificial hair, specifically: [0005] (1) Add pure polyacrylonitrile or binary or ternary copolymers of vinyl monomers containing less...
