Description
Technical Field
The invention relates to a regenerated cellulose fiber and a preparation method thereof, in particular to a regenerated cellulose fiber with deodorization and far infrared health care functions and a preparation method thereof, belonging to the technical field of fibers.
Background
With the continuous progress of the economy and the social civilization of China, the requirements of the masses on the living taste and the social environment are increasingly improved. By middle age, the body functions begin to decline slowly, the oxidation rate of the skin is increased, and besides the age spots are easy to appear, the oxidation of the skin can generate a substance named as 2-nonenal. Meanwhile, the oil secreted on the skin or the taste of some bacteria are mixed to generate the taste, which is commonly called as old taste or old odor. Hygiene and health care become the focus of people's attention.
The viscose fiber material disclosed in the Chinese invention patent CN104947218A and the preparation method thereof, the fiber with the antibacterial and deodorizing functions prepared by the patent technology is obtained by adding one or more of silicate compounds of silicon dioxide, sodium silicate, sodium aluminosilicate, potassium aluminosilicate, calcium silicate, magnesium silicate, potassium magnesium silicate or iron silicate into stock solution for spinning, and some of the substances are water-soluble and seriously lose in the production process. And the added solid substances are not protected and easily run off, so that the functionality and the durability of the product cannot be ensured. The invention discloses CN103556275B a far infrared bamboo charcoal viscose fiber and a preparation method thereof, wherein far infrared ceramic powder added in the patent technology is metal or metal oxide, sedimentation is easy to occur, and bamboo charcoal powder and far infrared ceramic powder are both solid, bamboo charcoal has very limited adsorption capacity on the bamboo charcoal, and the physical and mechanical properties and spinnability of the fiber are seriously influenced, thereby influencing the functionality of the fiber or fabric.
The invention discloses deodorizing fiber and a manufacturing method thereof, which is disclosed by the patent CN109943901A, and the fiber is prepared by adding zeolite powder and lauric acid into chinlon to form fiber master batch, carrying out melt spinning at the highest temperature of 280 ℃, leading the loss of lauric acid component to be serious at higher temperature, leading the prepared deodorizing fiber to have unsatisfactory functionality, and leading the fiber to be synthetic fiber and leading the product to be difficult to naturally degrade. The invention patent CN102839439A discloses a preparation method of a fiber for eliminating sweat and odor, which adopts a blended spinning technology, and takes nano zinc oxide as an odor eliminating agent to degrade the odor by utilizing the photocatalytic reaction. The nano powder is difficult to disperse, and meanwhile, as the nano powder is antibacterial through a photocatalysis mechanism, the antibacterial performance of the fiber cannot play a role under the condition of no illumination.
The above patents do not mention the elimination of 2-nonenal, the far infrared health care regenerated cellulose fiber produced by the invention has the far infrared function of increasing the function of human body and delaying aging, and the selected effective component of the deodorizer JYKZOT-92 is mainly silicate water dispersion liquid, is nontoxic and tasteless, and has good deodorization effect. However, the spinning forming process of the cellulose fiber is a strong acid system, and if the deodorant is directly added into the spinning solution without protection treatment, the loss is large, and the ideal deodorization effect cannot be achieved.
Disclosure of Invention
Aiming at the problems and the defects in the prior art, the invention provides a preparation method of deodorizing far infrared health care regenerated cellulose fiber, which realizes the following purposes: reduce the loss of the deodorizing agent, improve the deodorizing performance of the fiber and ensure the mechanical performance of the fiber at the same time.
In order to solve the technical problems, the invention adopts the following technical scheme:
a preparation method of deodorizing far infrared health care regenerated cellulose fiber comprises the steps of preparation of mixed slurry, preparation of blended spinning solution, spinning, post-treatment and deodorization finishing.
The preparation method comprises the following specific steps:
1. preparation of Mixed slurry
Slowly adding the bamboo charcoal powder and the deodorizing agent into deionized water in sequence under continuous stirring, stirring for 30min, adding a dispersing agent, grinding and dispersing for 30-60min by using a sand mill, and preparing slurry with the mass fraction of 20-35%, the particle size of less than or equal to 2um, and preferably 1.67-1.842 um.
The mass ratio of the bamboo charcoal to the deodorant in the mixed slurry is 2: 1;
the type of the deodorant is JYKZOT-92;
the dispersing agent is one or more of sodium hexametaphosphate, sodium tripolyphosphate, nano cellulose and animal gelatin;
the addition amount of the dispersant is 0.5-2wt% (relative to the weight of the dispersion).
2. Preparation of blended spinning solution
Cellulose pulp is used as a raw material, and a cellulose spinning solution is prepared by a conventional viscose preparation process and comprises the following components: 9.0-11% of alpha cellulose, 5.0-6.5% of sodium hydroxide and 50-70 s of falling ball viscosity, and adding the prepared mixed slurry into a viscose spinning solution through a dynamic or static mixer according to 1-10wt% of effective components (for alpha cellulose) to obtain a blended spinning solution.
3. Spinning
Spinning the blended spinning stock solution through a coagulating bath, wherein the coagulating bath comprises 80-90 g/L of sulfuric acid, 20-30 g/L of zinc sulfate and 260-320 g/L of sodium sulfate, and the temperature is 35-40 ℃. The fiber is slowly formed by a low-concentration low-temperature coagulating bath, so that the internal structure of fiber molecules is ensured to be neat, the orientation degree is higher, and the fiber has higher strength and elongation.
4. Deodorizing finishing
And cutting, desulfurizing and washing the spun tows, dewatering by a padder, performing a deodorizing finishing process for padding treatment, and finally oiling and drying to obtain the deodorizing far infrared health-care cellulose fiber. The deodorizing finishing process comprises the following steps: the moisture regain of the fiber before deodorization finishing is less than or equal to 120 percent, preferably is 103-120 percent; the concentration of the finishing liquid of the deodorizing agent is 5-10%, the temperature is 40-50 ℃, the time is 2-4min, and the moisture regain of the mangle fiber after deodorizing treatment is 100-.

1. the deodorizing far infrared health care regenerated cellulose fiber prepared by the invention has the dry breaking strength of more than or equal to 2.30cN/dtex, preferably 2.3-2.36 cN/dtex, the wet breaking strength of more than or equal to 1.1cN/dtex, preferably 1.13-1.18 cN/dtex, the dry breaking elongation of more than or equal to 18.0 percent, preferably 18.2-18.5 percent, the 2-nonenal elimination rate of more than or equal to 90 percent, preferably 90-96 percent, has a remarkable deodorizing function, and the far infrared normal emissivity of more than or equal to 0.80, preferably 0.8-0.85, and has the health care functions of activating cell tissues and promoting blood circulation.
2. The bamboo charcoal powder is prepared by firing alpine moso bamboos which are over three years old as raw materials at high temperature of nearly thousand ℃, the moso bamboos form a special pore structure in the high-temperature pyrolysis process, the specific surface area is large, the adsorption capacity is strong, the deodorant is well protected, and the loss in the production process is avoided.
3. According to the production process, the mixed slurry of the bamboo charcoal powder and the deodorizing agent is added into the viscose spinning solution through a dynamic or static mixer for spinning, and then deodorizing finishing is carried out in the post-treatment process, so that the loss of the deodorizing agent in the spinning process is reduced, and the durability of the function of the deodorizing agent is improved.
