The characteristics of compactness, fluffiness, suitability for embossing and the like of the product are met, and the texture, the density and the hair height of the fabric are the keys.

Preferably, the preparation method of the negative ion far infrared functional polyester bright fiber comprises the following steps:

A) dispersing illite-silicon dioxide composite aerogel particles into ethanol, adding antimony trioxide powder with the mass of 0.1-0.2 time that of the composite aerogel particles, uniformly stirring, heating to 80-90 ℃, keeping the temperature, standing, taking middle-upper-layer liquid, carrying out thermal filtration, and carrying out vacuum drying on the obtained solid to obtain the illite-silicon dioxide composite aerogel particles adsorbed with antimony trioxide;

B) adding the illite-silicon dioxide composite aerogel particles adsorbed with the antimony trioxide into ethylene glycol for ultrasonic dispersion to prepare a modified solution;

C) mixing terephthalic acid and ethylene glycol, stirring and heating to perform esterification reaction, adding a modification solution after the esterification reaction, performing polycondensation reaction, cooling after the reaction, and slicing to obtain a functional polyester slice with the content of illite-silicon dioxide composite aerogel particles of 0.5-2.5 wt%;

D) processing the functional polyester slices into negative ion far infrared functional polyester bright fibers according to a conventional polyester spinning process.

The anion far infrared terylene fiber which is purchased in the market has the health care function of the blanket because the fiber is compounded with inorganic mineral with the anion far infrared function. However, also because of the existence of inorganic minerals, the inorganic minerals and the polyester belong to inorganic and organic substances respectively, and have different properties during spinning, the inorganic minerals generate an adherent skin cutting effect during spinning, and the inorganic minerals migrate to the surface layer of the fiber to form a skin-core structure. The hardness of inorganic minerals is generally higher, which affects the skin-friendly property of the fiber and is not suitable for being used as a raw material of blanket used for being attached to the skin.

The invention specifically selects the self-made negative ion far infrared functional polyester lustrous fiber, has the advantages of small hardness, more softness and good skin-friendly property compared with similar products sold in the market, and is suitable to be used as the raw material of blanket used for sticking skin.

Illite is a clay mineral with a lamellar structure, has the anion far infrared function and has the health care effect. Each sheet of the material is irregular or angular. The illite is fine and smooth in texture and small in hardness after being crushed, so that the prepared fiber is low in hardness, softer and good in skin friendliness when being used as a functional addition material of the polyester fiber.

In order to further improve the skin-friendly properties of the fibers. The invention utilizes the adsorption characteristic of the illite-silicon dioxide composite aerogel particles to load the polyester synthesis catalyst antimony trioxide in the aerogel particles (namely between illite lamellar structures),

so, in polycondensation, with polyester chain growth reaction's place control in the aerogel particle, polycondensation is comparatively violent, can increase the interval between the illite lamella to make relative displacement take place easily between the lamella of illite, reduced its hardness, improved the flexibility.

Although the hardness of illite is relatively low, the illite is still not ideal for being used as a fabric for skin application if the illite is directly compounded into terylene. For this purpose, the present invention adds an inorganic material in the form of composite aerogel particles as a function.

Preferably, the method for preparing the illite-silica composite aerogel particles is as follows:

a) crushing illite, sieving with a 200-plus-300-mesh sieve, and calcining at the temperature of 250-plus-350 ℃ for 2-4h to obtain the illite powder.

In step a), illite is calcined in order to remove crystal water between the sheets, so that hydrolysis reaction can be generated between the sheets during the subsequent preparation of the aerogel.

b) Adding illite powder into toluene, adding azodiisocapronitrile which is 0.3-0.4 times of the illite powder in mass under the condition of ultrasonic dispersion, heating to 50-70 ℃ under the anaerobic condition, carrying out ultrasonic oscillation reaction for 2-4h, then carrying out suction filtration, and drying the obtained solid powder; adding the mixture into an alkaline ethanol aqueous solution, carrying out ultrasonic oscillation reaction for 10-20h at 70-80 ℃, adjusting the pH value to 3-4 after reaction, and finally carrying out suction filtration and drying to obtain the carboxylated modified illite powder.

On the one hand, the carboxylation modification provides conditions for the bonding of illite to the silica colloid in the subsequent step d); on the other hand, after the illite surface is treated by alkali and acid, the surface is etched, after the illite surface is compounded with polyester in the later period, molecules and atoms of a polyester molecule and an illite two-phase interface are easier to mutually permeate, invade, diffuse and migrate along with the time, an inorganic body and an organic matrix two-phase interface gradually form a new phase, namely an interface phase which is fully fused and different from the inorganic body and the organic matrix, the interface phase continuously spreads and expands along with the time, and the functions of the inorganic body are expanded along with the spreading. The interface phase can fully exert the anion far infrared function due to the full fusion of the inorganic material and the organic matrix. In addition, the illite can also improve the aging resistance of the polyester, and after the illite forms an interface phase with an organic matrix, compared with a common aging resistance additive, the illite has a longer functional period, and the aging resistance effect is better.

c) Adding the carboxylated modified illite powder into 1-2 times of ethyl orthosilicate by mass, uniformly stirring, then respectively adding 3-5 times of water and 4-6 times of ethanol by mass of the carboxylated modified illite powder, performing ultrasonic dispersion to obtain a suspension, adjusting the pH value of the suspension to 3.5-4.5, and performing hydrolysis reaction for 1-2 days.

In the step c), illite and tetraethoxysilane are dispersed uniformly by ultrasound, so that tetraethoxysilane penetrates between illite sheet structures. This reaction occurs between the illite sheet structures as the tetraethylorthosilicate hydrolyzes. Because hydrolysis reaction is comparatively violent, can increase the lamella interval, the reaction back lamella is interbedded and is produced the silica colloid, and illite lamella forms the structure similar to "intermediate layer biscuit" with the silica colloid, and the packing of silica colloid makes the lamella interval of later stage illite unable shrink, keeps better flexibility all the time.

d) Adding amino silane which is 0.3 to 0.7 times of the mass of the carboxylated modified illite powder into the hydrolyzed suspension, adjusting the pH of the suspension to be 8.5 to 9, and slowly stirring for reaction for 1 to 2 hours to prepare composite sol; standing and aging for 2-3 days at room temperature, and washing with ethanol to obtain illite-silicon dioxide composite wet gel.

The silica colloid is substantially present in the form of silicon hydroxide in solution and contains a large number of hydroxyl groups. In order to ensure a stable colloidal filling between the illite lamellae, the present invention deliberately selects aminosilanes for "bridging" in step d): the silane group and the amino group on the aminosilane molecule can be respectively combined with the hydroxyl group of the colloid and the carboxyl group on the illite (through carboxylation modification, the amido group and the carboxyl group produce amido bond), and the colloid is fixed between the illite sheets.

e) And (3) replacing the original solvent in the composite wet gel with n-hexane, drying the composite wet gel by using a supercritical fluid, and grinding to obtain the illite-silicon dioxide composite aerogel particles.
