Abstract

This invention discloses a magnesium ion slow-release particle, its preparation method, and its application in functional home textile yarns, relating to the field of functional home textile materials. The slow-release particle uses mesoporous silica-loaded magnesium salt as a precursor, coated with polylactic acid-polyethylene glycol block copolymer (PLA-PEG) as a slow-release layer, and is prepared by an emulsion-solvent evaporation method combined with freeze-drying. The particle is then loaded onto the surface of modified cotton fibers pretreated with the adhesive using an adhesive, penetration enhancer, and dispersant under ultrasonic assistance. The yarn is then processed through opening, carding, drawing, roving, and spinning to produce functional home textile yarns. This invention solves the problems of easy magnesium ion aggregation, rapid loss, and poor binding strength through a dual slow-release structure design and synergistic fiber pretreatment and spinning processes, achieving long-term slow release of magnesium ions. The resulting yarn has high breaking strength and uniform evenness, and the fabric woven from it exhibits a stable magnesium ion slow-release rate in simulated sweat, making it suitable for preparing home textile products that improve sleep quality.

Description

Technical Field

[0001] This invention belongs to the field of functional materials technology for home textiles, specifically relating to a magnesium ion slow-release particle, its preparation method, and its application in functional home textile yarns. Background Technology

[0002] Sleep quality is closely related to human health. Magnesium ions, as an essential trace element for the human body, are activators of key enzymes in the process of melatonin synthesis. They can promote melatonin secretion by regulating the hypothalamus-pituitary-pineal axis, thereby improving sleep rhythm.

[0003] Currently, most sleep-aid home textile products focus on the physical aspects, such as blackout fabrics, temperature-regulating mattresses, and sound-insulating pillows. These only optimize the sleep environment and cannot regulate bodily functions at the physiological level. The few magnesium-containing sleep aids available are mostly oral preparations, which have problems such as gastrointestinal irritation and low absorption efficiency, and cannot provide continuous supplementation. Therefore, developing a functional home textile product that can be absorbed transdermally and provides long-lasting, sustained-release magnesium supplementation has broad market prospects.

[0004] Loading magnesium ions into home textile yarns and achieving slow-release replenishment through potential transdermal absorption is a possible approach to solving the above problems. However, the direct addition of magnesium ions in existing technologies is prone to problems such as agglomeration, rapid loss, and poor slow-release properties, making it difficult to meet the long-term use needs of home textile products. Summary of the Invention

[0005] Technical problems to be solved: In view of the technical defects of existing technologies, such as uneven loading of magnesium ions in home textile products, gastrointestinal irritation and low absorption efficiency of magnesium-containing sleep aid products, and easy agglomeration, rapid loss and poor sustained release when magnesium ions are directly added, this application provides magnesium ion sustained-release particles, their preparation method and their application in functional home textile yarns.

[0006] Purpose of the invention: The purpose of this invention is to provide magnesium ion slow-release particles, their preparation method, and their application in functional home textile yarns, so as to achieve long-term slow release of magnesium ions in home textile products; these slow-release magnesium ions have the potential for transdermal absorption and are expected to serve as an auxiliary way to supplement magnesium in addition to daily diet, providing the human body with a gentle magnesium ion supplement, especially suitable for people who are concerned about sleep quality.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A magnesium ion slow-release particle, the magnesium ion slow-release particle comprising: a magnesium salt-loaded mesoporous silica precursor and a polylactic acid-polyethylene glycol block copolymer PLA-PEG slow-release layer coated on the surface of the magnesium salt-loaded mesoporous silica precursor.

[0008] Furthermore, the magnesium salt is one or more of magnesium chloride, magnesium sulfate, and magnesium acetate; the pore size of the mesoporous silica is 5–20 nm, and the particle size of the slow-release particles is 1–2 μm; the number average molecular weight of the PLA-PEG is 20,000–50,000, and the mass fraction of PEG segments is 10%–30%.

[0009] Furthermore, the loading of the magnesium salt is 10% to 20% of the mass of the mesoporous silica, and the mass of the PLA-PEG slow-release layer is 20% to 30% of the total mass of the slow-release particles.

[0010] Furthermore, any of the above-mentioned methods for preparing magnesium ion sustained-release particles includes the following steps: Step A, Precursor Preparation: Dissolve magnesium salt in deionized water to prepare a magnesium salt solution with a mass fraction of 10% to 30%. Add mesoporous silica at a mass ratio of magnesium salt to mesoporous silica of 2 to 5:1. Stir at 200 to 500 rpm for 12 to 24 h at room temperature, then filter and dry at 60 to 80 °C for 12 to 20 h to obtain a magnesium salt-loaded mesoporous silica precursor. Step B, emulsion preparation: PLA-PEG is dissolved in dichloromethane to prepare an organic phase with a mass fraction of 5% to 15%; the precursor obtained in step A is dispersed in a polyvinyl alcohol aqueous solution with a mass fraction of 0.5% to 2% to form an aqueous phase; the organic phase and the aqueous phase are mixed at a volume ratio of 1:2 to 5 to obtain a mixture. Step C, Coating and Shaping: The mixture in Step B is emulsified at 1000-2000 rpm for 10-30 min to form an emulsion. Then, the dichloromethane is evaporated by stirring at 30-40℃ for 2-4 h, so that PLA-PEG is deposited on the surface of the precursor to form a coating layer. After centrifugation and freeze-drying, magnesium ion slow-release particles are obtained.

[0011] This application also discloses a functional home textile yarn containing any of the aforementioned magnesium ion slow-release particles, manufactured using a method comprising the following steps: Step 1, Modification treatment of cotton fibers: Immerse cotton fibers in an adhesive solution with a mass fraction of 2% to 5% at a bath ratio of 1:10 to 20 for 10 to 20 minutes. After removal, pre-dry at 80 to 100°C until the moisture content is 8% to 12% to obtain modified cotton fibers. Step 2, loading magnesium ion slow-release particles: Add 10-20 parts of magnesium ion slow-release particles, 2-4 parts of penetration enhancer, and 1-2 parts of dispersant to 100 parts of deionized water to prepare a treatment solution according to the mass ratio. Immerse the modified cotton fiber obtained in Step 1 into the treatment solution at a bath ratio of 1:5-10, sonicate for 15-30 min at an ultrasonic power of 200-400 W, and dry at 60-80℃ to obtain cotton fiber loaded with magnesium ion slow-release particles. Step 3, spinning: The cotton fibers loaded with magnesium ion slow-release particles are fed into the spinning equipment and successively go through the processes of opening, carding, drawing, roving and spinning to produce functional home textile yarn containing magnesium ion slow-release particles.

[0012] Furthermore, the adhesive is one or more of polyurethane acrylate, polyurethane, and polyacrylate; the penetration enhancer is one or more of N-methyl-2-pyrrolidone, glycerol, and isosorbide dimethyl ether; and the dispersant is polyethylene glycol 400.

[0013] Furthermore, in step 3, the draft ratio of the roving process is controlled to be 5-10, and the roving twist coefficient is controlled to be 80-120; in step 3, the draft ratio of the spinning process is controlled to be 25-35, and the spinning twist coefficient is controlled to be 300-400.

[0014] Furthermore, the fabric woven from the aforementioned yarn was tested at 37°C in simulated sweat at pH 5.5, and the average sustained release rate of magnesium ions over 24 hours was 12–18 μg / (cm³). 2 ·d).

[0015] Explanation of the principle: This application uses mesoporous silica to support magnesium salts to prepare a precursor, achieving efficient loading and stable storage of magnesium salts, avoiding problems such as agglomeration and rapid loss caused by direct addition of magnesium ions. Furthermore, a polylactic acid-polyethylene glycol block copolymer (PLA-PEG) layer is coated onto the surface of the precursor. This coating layer has good biocompatibility and controllable degradation. Through the slow degradation and swelling of the copolymer in a simulated sweat environment, mesoporous channels are gradually opened, achieving long-term, uniform, and controllable release of magnesium ions, preventing rapid loss. The two work synergistically to ensure a high magnesium salt loading while achieving precise control of the release period and rate, meeting the long-term use requirements of home textile products. An adhesive is applied to the surface of the cotton fibers. It forms a continuous viscous film, increases the surface roughness and adhesion sites of the fibers, enhances the binding strength between magnesium ion slow-release particles and cotton fibers, prevents particles from falling off during spinning, weaving and washing, and ensures long-lasting functionality. The dispersant can reduce the interfacial tension and agglomeration tendency of magnesium ion slow-release particles, improve the dispersion stability of particles in aqueous dispersion, ensure that particles are evenly distributed on the surface and inside of cotton fibers, and avoid local aggregation that affects yarn strength and hand feel. The penetration enhancer has the ability to hydrate the stratum corneum of the skin and form aqueous channels to assist magnesium ions in penetrating the skin barrier. In the spinning process, the process parameters of roving and spinning are matched to ensure stable yarn quality, so that the functional home textile yarn has both excellent mechanical properties and long-lasting magnesium ion slow-release function.

[0016] The present invention has the following beneficial effects: (1) Stable sustained-release performance: Through the dual structural design of "mesoporous silica loading" and "PLA-PEG coating", the controlled release of magnesium ions is realized. This structure effectively solves the problems of easy agglomeration and excessively rapid release of magnesium ions when added directly, so that the fabric can provide a stable and long-lasting sustained-release function of magnesium ions during long-term use; the average sustained-release rate of magnesium ions in the fabric made with the functional yarn of the present invention can be stably controlled at 12-18 μg / (cm) 2 ·d), compared with technical solutions that do not use mesoporous silica loading or PLA-PEG coating, it effectively suppresses the "burst release" phenomenon and significantly prolongs the release time; Excellent yarn performance: Through adhesive pretreatment and optimized spinning process, it is ensured that magnesium ion slow-release particles can be firmly and uniformly loaded onto cotton fibers and smoothly processed into yarn, so that the final functional home textile yarn has both good spinnability and wearability; the breaking strength and evenness CV value of the functional yarn of this invention are not much different from those of conventional yarn, and are significantly better than those of unpretreated or unoptimized spinning processes. Safe and gentle effects: Slow-release magnesium ions have the potential for transdermal absorption, eliminating the need for oral administration and avoiding gastrointestinal irritation. It can be used as an adjunct to daily diet for magnesium supplementation and is suitable for people who are concerned about sleep quality or have mild magnesium deficiency. Detailed Implementation

[0024] Example 3: A method for preparing magnesium ion sustained-release particles, the method comprising the following steps: Step A: Weigh magnesium acetate and dissolve it in deionized water to prepare a 20% magnesium acetate solution; add mesoporous silica with a pore size of 10 nm at a magnesium salt to mesoporous silica mass ratio of 3:1, stir at 380 rpm for 20 h at room temperature, filter, and dry at 70℃ for 16 h to obtain a magnesium salt-loaded mesoporous silica precursor, with the magnesium salt loading being 15% of the mass of the mesoporous silica; Step B: Dissolve PLA-PEG with a number average molecular weight of 40,000 and a PEG segment mass fraction of 20% in dichloromethane to prepare an organic phase with a mass fraction of 10%; disperse the precursor in a polyvinyl alcohol aqueous solution with a mass fraction of 1% to form an aqueous phase; mix the organic phase and the aqueous phase at a volume ratio of 1:4. Step C: The mixture was emulsified at 1500 rpm for 20 min to form an emulsion; dichloromethane was evaporated by stirring at 35℃ for 3 h; centrifugation and freeze drying were performed to obtain magnesium ion slow-release particles with a particle size of 1.5 μm; the mass of the PLA-PEG slow-release layer was 25% of the total mass of the particles.

[0025] The functional home textile yarn containing the magnesium ion slow-release particles is manufactured using a method comprising the following steps: Step 1, cotton fiber modification: Immerse cotton fibers in a 3% (w / w) polyurethane aqueous solution at a liquor ratio of 1:15 for 15 minutes; after removal, pre-dry at 90℃ until the moisture content is 10% to obtain modified cotton fibers. Step 2, loading magnesium ion slow-release particles: 15 parts by weight of magnesium ion slow-release particles, 3 parts by weight of isosorbide dimethyl ether, and 1.5 parts by weight of polyethylene glycol 400 were added to 100 parts by weight of deionized water to prepare a treatment solution; modified cotton fibers were immersed in the treatment solution at a bath ratio of 1:8, ultrasonically treated at 300 W for 20 min, and dried at 70℃ to obtain cotton fibers loaded with magnesium ion slow-release particles. Step 3, Spinning: The fibers loaded with magnesium ion slow-release particles are sequentially processed through opening, carding, drawing, roving, and spinning to obtain the functional home textile yarn. The roving has a draft ratio of 8 and a twist coefficient of 100; the spinning has a draft ratio of 30 and a twist coefficient of 350. This yields the functional home textile yarn of Example 3.

[0026] In Comparative Example 1, the magnesium salt particles were prepared without the mesoporous silica loading step A, and were directly coated with a polylactic acid-polyethylene glycol block copolymer (PLA-PEG) sustained-release layer. The remaining yarn preparation steps were exactly the same as in Example 1.

[0027] In Comparative Example 2, the magnesium salt-loaded mesoporous silica precursor was not coated with a polylactic acid-polyethylene glycol block copolymer (PLA-PEG) slow-release layer during particle preparation. The remaining yarn preparation steps were exactly the same as in Example 1.

[0028] Comparative Example 3: The cotton fibers were not modified with adhesives. The rest was the same as in Example 1.

[0029] Comparative Example 4 uses the same method for preparing the slow-release granules and yarn as in Example 1, but the spinning parameters in step 3 are changed to: roving draft ratio 3, roving twist coefficient 60; yarn draft ratio 20, yarn twist coefficient 250. The rest is the same as in Example 1.

[0030] Yarn properties: Breaking strength (cN / tex) and elongation at break (%) were tested using a fully automated single yarn tensile strength tester; yarn evenness CV value (%) was tested using an Uster evenness tester. Release rate: Yarns were woven into fabrics of the same specifications and immersed in simulated sweat (pH 5.5) at 37°C. After 24 hours, the magnesium ion concentration was measured, and the average release rate was calculated in μg / (cm³). 2 ·d). Data from Examples 1-3 and Comparative Examples 1-4 are shown in Table 1.

[0031] Table 1 .

[0032] Examples 1-3 show that the functional yarns exhibit excellent physical properties, and the fabrics prepared from these yarns possess good and stable magnesium ion sustained-release performance. In Comparative Example 1, due to the lack of mesoporous silica confinement, the PLA-PEG coating layer struggles to effectively control the release, resulting in a significant burst release, and particle agglomeration leads to a decrease in the strength of the functional yarn. Comparative Example 2 lacks a sustained-release layer, allowing magnesium ions to rapidly diffuse and release from the mesoporous silica channels in simulated sweat, thus failing to achieve long-term sustained release.

[0033] Comparative Example 3: The cotton fiber surface lacks an adhesive film formed by the adhesive, has insufficient roughness and adhesion sites, and the magnesium ion slow-release particles have poor bonding strength with the fiber. As a result, the particles fall off severely during spinning, opening, carding and subsequent weaving processes, and the fallen particles cause a decrease in yarn strength.

[0034] In Comparative Example 4, an excessively low roving draft ratio resulted in poor fiber straightness in the sliver, and an excessively low roving twist coefficient led to insufficient roving strength. Similarly, an excessively low yarn draft ratio resulted in poor fiber separation in the sliver, and an excessively low yarn twist coefficient resulted in excessive hairiness, low strength, and uneven yarn evenness. The overall yarn quality significantly decreased, and the uneven distribution of particles in the yarn affected the sustained-release stability.

[0035] In summary, only by systematically combining "magnesium ion slow-release particles with specific structures," "fiber pretreatment process," and "optimized spinning process" can functional home textile yarns with excellent slow-release and mechanical properties be obtained. Example 1 is the preferred embodiment of the present invention.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. The present invention has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
