Description

Technical Field

[0001] This invention belongs to the field of functional fiber products technology, specifically relating to a multifunctional health and wellness quilt based on human body structure and gravity, and its preparation method. Background Technology

[0002] A quilt is a type of bedding, a rectangular piece of fabric large enough to cover the human body, generally used for warmth during sleep. Quilts typically consist of a quilt cover or sheet wrapped with cotton batting; quilts made of cotton are called cotton quilts. Besides cotton, quilts can also be made from wool, silk, or synthetic fibers such as polyester, cellulose, polylactic acid, viscose, and cellulose acetate.

[0003] Functional fibers refer to fibers that possess additional special functions beyond their existing properties. Examples include far-infrared, negative ion, antibacterial, and antiviral fibers. Functional fibers are generally prepared from synthetic fibers through a blending method, offering advantages such as low cost and high effectiveness. The main technical challenge of the blending method lies in achieving compatibility between functional components with different properties and the fiber matrix, ensuring that the corresponding functions are effectively utilized without severely degrading the fiber's mechanical properties. For instance, in our previous patents CN 111519341 B and CN 113652766 B, we developed silica aerogel microsphere loading technology and PVA-SiO2 interpenetrating network technology to reduce the adverse effects of blended functional materials on the fiber's mechanical strength.

[0004] Furthermore, most existing quilts use a one-piece, uniform structure design, failing to consider the varying needs for warmth and weight distribution in different parts of the human body. Specifically, the lower body (below the waist and thighs) has the highest need for warmth, as cold enters the body through the legs, which have low self-heating capacity. The feet and legs, being relatively short in volume and long, can bear the heaviest weight. The abdomen requires less warmth and can withstand less pressure than the legs and feet, but when the feet and legs are not warm enough, it exacerbates the transfer of heat from the abdomen to the feet and legs, leading to insufficient warmth in the abdomen and causing gastrointestinal discomfort and indigestion. The heart, liver, stomach, lungs, shoulders, and neck all require less warmth and can withstand less pressure than the abdomen, with the heart being particularly vulnerable to increased pressure on its blood supply.

[0005] Patent CN 204071456U discloses a quilt designed to conform to human ergonomics. It divides the quilt into a perimeter and a central area using rows, with the perimeter area having the highest filling density. This ensures the quilt drapes naturally around the perimeter, conforming to the body in all directions. Since the upper body requires less heat than the lower body, the central area of ​​the quilt is designed with larger squares in the upper half and smaller squares in the lower half. The filling density is lower in the upper half than in the lower half, thus avoiding pressure on areas such as the neck and heart. However, this design is relatively complex and cannot provide health benefits such as far-infrared radiation, negative ions, antibacterial properties, or antiviral effects.

[0006] Therefore, developing a multifunctional health and wellness blanket based on human body structure and gravity has promising application prospects. Summary of the Invention

[0007] To address the shortcomings and deficiencies of the existing technologies, the primary objective of this invention is to provide a multifunctional health and wellness quilt based on human body structure and gravity. This multifunctional health and wellness quilt is designed with a three-section human body structure and incorporates corresponding far-infrared, negative ion, antibacterial, and antiviral health and wellness functions, achieving a perfect combination of warmth and multifunctional health and wellness.

[0008] Another objective of this invention is to provide a method for preparing the above-mentioned multifunctional health and wellness quilt based on human body structure and gravity.

[0009] The objective of this invention is achieved through the following technical solution:

[0010] A multifunctional health and wellness quilt based on human body structure and gravity is formed by three-tiered ordinary fiber or health-promoting multifunctional fiber mesh. The health-promoting multifunctional fiber mesh refers to a fiber mesh with at least one of the following functions: far-infrared, negative ion, antibacterial, and antiviral. The first tier of the fiber mesh corresponds to the area below the waist and thighs of the human body, accounting for 5 / 10 to 7 / 10 of the total quilt length, with a unit area weight of 0.1 to 2 kg / m². 2 The second-tier fiber mesh corresponds to the abdomen part of the human body structure, accounting for 1 / 10 to 3 / 10 of the total length of the quilt, and its unit area weight is 60% to 80% of the first-tier fiber mesh. The third-tier fiber mesh corresponds to the heart, liver, stomach, lungs, shoulders and neck parts of the human body structure, accounting for 1 / 10 to 3 / 10 of the total length of the quilt, and its unit area weight is 50% to 70% of the second-tier fiber mesh.

[0011] It should be noted that the quilt structure of this invention, which is based on the human body structure and gravity design, is not limited to health care multifunctional fiber materials. Other non-functional fiber materials can still achieve the function of warmth retention based on the human body structure and gravity.

[0012] More preferably, the unit area weight ratio of the first-stage fiber mesh, the second-stage fiber mesh, and the third-stage fiber mesh is 7:5:3. This ratio best suits the human body's needs for warmth and weight control in a quilt. The lower body, thighs, and feet are more susceptible to cold, so the corresponding quilt portion is thicker and warmer, preventing the feet from getting cold. Meanwhile, the abdomen, heart, liver, stomach, lungs, shoulders, and neck areas are thinner, resulting in a more comfortable and less oppressive feeling when covered.

[0013] The preparation method of the above-mentioned multifunctional health and wellness quilt based on human body structure and gravity includes the following preparation steps:

[0014] Ordinary fibers or health-care multifunctional fibers, or a combination of ordinary fibers or health-care multifunctional fibers and bonding materials, or a combination of health-care multifunctional fibers, ordinary fibers and bonding materials, are opened and then sent to a carding machine. The fibers are carded into a web according to three-level gradient length and weight parameters, dried and shaped to obtain a multifunctional health-care quilt based on human body structure and gravity.

[0015] Furthermore, the adhesive material is a low-melting-point fiber or an adhesive such as glue.

[0016] Furthermore, the common fiber is at least one of natural plant fiber, animal fiber, or artificial synthetic fiber.

[0023] Furthermore, the mass concentration of PVA in the mixture described in step (1) is 5% to 30%.

[0024] Further, the hydrogen-containing silicone oil mentioned in step (2) is a hydrogen-containing silicone oil with a hydrogen content of 0.4% to 1.5% (wt%) and a viscosity of 50 to 1000 mPa·s at 25°C.

[0025] Furthermore, the terminal diene-capped polyether described in step (2) has a molecular weight of 300–1200, and its molecular formula is as follows:

[0026] CH2=CHCH2O(CH2CH2O) n (CH2CH(CH3)O) m CH2CH=CH2; m and n are integers from 0 to 25.

[0027] Furthermore, the amount of diene-terminated polyether added in step (2) is 0.02 to 0.3 times the molar amount of hydrogen in the hydrogen-containing silicone oil.

[0028] Further, the organic solvent mentioned in step (2) is at least one of ethanol, propanol, isopropanol, butanol, and isobutanol.

[0034] Further, in step (4), the mass ratio of the PVA-silicone rubber composite particles to the fiber matrix is ​​1-20:80-99.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] (1) The multifunctional health and wellness quilt of this invention is based on a three-section human body structure design. Considering the human body's needs for warmth and gravity in a quilt, the lower body and feet are more susceptible to cold, so the corresponding quilt section is thicker and warmer, preventing the feet from getting cold. Meanwhile, the abdomen and the areas for the heart, liver, stomach, lungs, shoulders, and neck are thinner, so the quilt is less oppressive and more comfortable. It also provides corresponding far-infrared, negative ion, antibacterial, and antiviral health and wellness functions, achieving a perfect combination of warmth and multifunctional health and wellness.

[0037] (2) The present invention uses specific cross-linked silicone rubber as a fiber reinforcing material, which can significantly improve the strength and anti-aging properties of fiber materials.

[0038] (3) The PVA-silicone rubber composite particles prepared by the present invention through a specific method solve the defect of poor compatibility between silicone rubber and fiber materials, and can play a plasticizing role, enhance spinnability and dispersibility, and achieve significant improvement in strength and anti-aging properties. Detailed Implementation

[0039] The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0040] Example 1

[0041] This embodiment of a multifunctional health and wellness blanket based on human body structure warmth retention and gravity, with antibacterial and antiviral far-infrared negative ions, is prepared by the following method:

[0042] The multifunctional polyester fiber with antiviral, antibacterial, far-infrared, and negative ion properties, derived from traditional Chinese medicine, is opened and then fed into a carding machine. It is carded into a web according to three-stage gradient length and weight parameters. The first stage of the fiber web corresponds to the human body structure below the waist and thighs, accounting for 3 / 5 of the total quilt length, with a unit area weight of 0.7 kg / m². 2 The second-stage fiber mesh corresponds to the abdomen area of ​​the human body, accounting for 1 / 5 of the total length of the quilt, with a unit area weight of 0.5 kg / m². 2 The third-level fiber mesh corresponds to the human body's structure, specifically the heart, liver, stomach, lungs, shoulders, and neck. It accounts for 1 / 5 of the total length of the quilt, with a unit area weight of 0.3 kg / m². 2 Then, it undergoes multi-layered energy drying and shaping (using different air volumes, wind speeds, and heat levels according to different weights, lengths, and thicknesses), and is collected into rolls in a left-high, right-low gradient pattern, resulting in a multi-functional health and wellness quilt with antibacterial, antiviral, far-infrared, and negative ion properties based on human body structure and gravity.

[0043] The multifunctional polyester fiber with antiviral, antibacterial, far-infrared negative ion properties of traditional Chinese medicine used in this embodiment was prepared by the following method:

[0044] (1) Five parts by weight of the antiviral extract of traditional Chinese medicine (water decoction extract of Artemisia argyi, Isatis indigotica, Taraxacum mongolicum, Lonicera japonica, Chrysanthemum indicum and Isatis tinctoria) and 95 parts by weight of PVA aqueous solution (PVA mass concentration of 20%) were heated and stirred to dissolve evenly to obtain a mixed solution.

[0045] (2) Mix 100 parts by weight of hydrogen-containing silicone oil (hydrogen content of 0.45%, viscosity of 650 mPa·s at 25℃) with 80 parts by weight of diene-terminated polyether (CH2=CHCH2O(CH2CH2O)). n (CH2CH(CH3)O) m CH2CH=CH2 (average molecular weight 1000, commercially available) was added to a mixed solvent of 1000 parts by weight of ethanol and isopropanol and stirred until dissolved. The mixture was heated to 75-85°C under nitrogen protection, and then a chloroplatinic acid isopropanol solution catalyst was added dropwise and stirred for 5 hours to obtain a silicone rubber elastomer solution.

[0046] (3) The mixture from step (1) and the silicone rubber elastomer solution from step (2) are heated and stirred to mix evenly at a weight ratio of 1:2. Then, 5% nano silver oxide powder, 3% nano tourmaline negative ion powder and 3% nano far-infrared ceramic powder are added and stirred to mix evenly. The solvent is removed by vacuum drying to obtain PVA-silicone rubber composite particles with inorganic functional nanoparticles as the core and coated with antiviral components of traditional Chinese medicine.

[0047] (4) The PVA-silicone rubber composite particles with inorganic functional nanoparticles as the core and coated with antiviral components of traditional Chinese medicine obtained in step (3) are added to the extruder at a mass ratio of 12:88 and melt-blended spinning to obtain multifunctional polyester fiber with antiviral, antibacterial and far-infrared negative ions of traditional Chinese medicine.

[0048] The antibacterial, antiviral, far-infrared, and negative ion multifunctional polyester fiber obtained in this embodiment was tested for antibacterial properties (according to "GB / T 20944.3-2008 Oscillation Method"; test bacteria were Staphylococcus aureus and Escherichia coli), antiviral properties (ISO18184-2014, test virus coronavirus Hcov-229E), far-infrared properties (CAS115-2005, health-functional textiles), negative ion properties (tested using an atmospheric ion concentration relative standard measuring device), mechanical strength (ISO 5079-1995), and anti-aging properties (AATCC186-2009, UV-A fluorescent lamp, irradiation intensity 0.77W / m²). 2 The test was conducted at an irradiation time of 720 hours and a relative humidity of 65±2%, and pure polyester fiber material was used as a comparison. The results are shown in Table 1 below.

[0052] As shown in Table 1, the multifunctional polyester fiber obtained by this invention possesses excellent antiviral, antibacterial, far-infrared, and negative ion properties, as well as significantly improved mechanical strength and anti-aging properties. The multifunctional health and wellness quilt prepared from it achieves a perfect combination of warmth and multifunctional health benefits.

[0053] Example 2

[0054] This embodiment of the antibacterial and antiviral multifunctional health and wellness quilt, based on human body structure warmth and gravity, compared with embodiment 1, uses Chinese herbal antiviral and antibacterial negative ion multifunctional cellulose acetate fiber instead of Chinese herbal antiviral and antibacterial far-infrared negative ion multifunctional polyester fiber.

[0055] The multifunctional cellulose acetate fiber with antiviral, antibacterial, and negative ion properties, derived from traditional Chinese medicine, is prepared by the following method:

[0056] (1) Five parts by weight of the antiviral extract of traditional Chinese medicine (water decoction extract of Artemisia argyi, Isatis indigotica, Taraxacum mongolicum, Lonicera japonica, Chrysanthemum indicum and Isatis tinctoria) and 95 parts by weight of PVA aqueous solution (PVA mass concentration of 20%) were heated and stirred to dissolve evenly to obtain a mixed solution.

[0057] (2) Mix 100 parts by weight of hydrogen-containing silicone oil (hydrogen content of 1.05%, viscosity of 75 mPa·s at 25℃) with 20 parts by weight of diene-terminated polyether (CH2=CHCH2O(CH2CH2O)). n (CH2CH(CH3)O) m CH2CH=CH2 (average molecular weight 400, commercially available) was added to a mixed solvent of 1000 parts by weight of ethanol and isopropanol and stirred until dissolved. The mixture was heated to 75-85°C under nitrogen protection, and then a chloroplatinic acid isopropanol solution catalyst was added dropwise and stirred for 4 hours to obtain a silicone rubber elastomer solution.

[0058] (3) The mixture in step (1) and the silicone rubber elastomer solution in step (2) are heated and stirred evenly at a weight ratio of 2:1. Then, 5% nano tourmaline negative ion powder and 5% nano silver oxide powder are added and stirred evenly. The solvent is removed by vacuum drying to obtain PVA-silicone rubber composite particles with inorganic functional nanoparticles as the core and coated with antiviral components of traditional Chinese medicine.

[0059] (4) The PVA-silicone rubber composite particles with inorganic functional nanoparticles as the core and coated with the antiviral components of traditional Chinese medicine obtained in step (3) are added to the extruder at a mass ratio of 6:94 and melt-blended spinning to obtain multifunctional cellulose acetate fiber with antiviral, antibacterial and negative ion properties of traditional Chinese medicine.

[0060] The antibacterial, antiviral, negative ion, mechanical strength, and anti-aging properties of the multifunctional cellulose acetate fiber with antiviral, antibacterial, and negative ion properties obtained in this embodiment were tested, and pure cellulose acetate fiber material was used as a comparison. The results are shown in Table 2 below.

[0063] As shown in Table 2, the multifunctional cellulose acetate fiber material obtained in this invention possesses excellent antibacterial, antiviral, and negative ion properties, as well as significantly improved mechanical strength and anti-aging properties. The multifunctional health and wellness quilt prepared from it achieves a perfect combination of warmth and multifunctional health benefits.

[0064] Comparative Example 1

[0065] Compared with Example 1, the preparation process of the multifunctional polyester fiber with antiviral and antibacterial properties of traditional Chinese medicine and far-infrared negative ions does not involve the addition of PVA components, but is otherwise the same. The specific preparation steps are as follows:

[0066] (1) Mix 5 parts by weight of the antiviral extract of traditional Chinese medicine (water decoction extract of Artemisia argyi, Isatis indigotica, Taraxacum mongolicum, Lonicera japonica, Chrysanthemum indicum and Isatis tinctoria) with 95 parts by weight of deionized water to obtain a mixed solution.

[0067] (2) Mix 100 parts by weight of hydrogen-containing silicone oil (hydrogen content of 0.45%, viscosity of 650 mPa·s at 25℃) with 80 parts by weight of diene-terminated polyether (CH2=CHCH2O(CH2CH2O)). n (CH2CH(CH3)O) m CH2CH=CH2 (average molecular weight 1000, commercially available) was added to a mixed solvent of 1000 parts by weight of ethanol and isopropanol and stirred until dissolved. The mixture was heated to 75-85°C under nitrogen protection, and then a chloroplatinic acid isopropanol solution catalyst was added dropwise and stirred for 5 hours to obtain a silicone rubber elastomer solution.

[0068] (3) The mixture of step (1) and the silicone rubber elastomer solution of step (2) are heated and stirred evenly at a weight ratio of 1:2. Then, 5% nano silver oxide powder, 3% nano tourmaline negative ion powder and 3% nano far-infrared ceramic powder are added and stirred evenly. The solvent is removed by vacuum drying to obtain silicone rubber composite particles with inorganic functional nanoparticles as the core.

[0069] (4) The silicone rubber composite particles with inorganic functional nanoparticles as the core obtained in step (3) are added to the polyester chips at a mass ratio of 12:88 and then melt-blended and spun to obtain the multifunctional polyester fiber with antiviral, antibacterial and far-infrared negative ions of traditional Chinese medicine.

[0070] The antibacterial, antiviral, far-infrared, negative ion multifunctional polyester fiber material obtained in this comparative example was tested for antibacterial properties, antiviral properties, far-infrared properties, negative ion properties, mechanical strength, and anti-aging properties. The results are shown in Table 3 below.

[0071] Table 3

[0072] Staphylococcus aureus inhibition rate 98％ E. coli inhibition rate 99％ Antiviral activity rate 91％ negative ion generation <![CDATA[880 per cm 3 > Far-infrared emissivity 0.88 Fracture strength 6.2cN / dtex Elongation at break 43％ Strength retention rate 80.6％ Elongation retention rate 76.7％

[0073] As shown in Table 3, compared to Example 1, the antiviral activity of the fiber material decreased to some extent without the addition of PVA, but had no significant adverse effect on the inorganic antibacterial, negative ion, and far-infrared properties. This indicates that the coating effect of PVA promotes the performance of the antiviral active ingredients of traditional Chinese medicine in the fiber material without affecting the performance of inorganic functional components such as antibacterial, negative ion, and far-infrared properties. Furthermore, the mechanical strength and anti-aging properties of the fiber material decreased significantly without the addition of PVA. This is because the simple silicone rubber elastomer solution, after drying, forms polysiloxane particles with strong hydrophobic and oleophobic surfaces. These particles have poor compatibility and thermoplasticity with the fiber material, and cannot achieve good dispersion and optimal reinforcement during melt blending and spinning. The PVA-silicone rubber composite particles formed by pre-mixing PVA solution with silicone rubber elastomer solution to create a swollen structure and then drying exhibit enhanced thermoplasticity. Furthermore, the PVA component and exposed polyether crosslinking components in the composite particles improve the compatibility between the composite particles and the fiber material, significantly improving the reinforcing effect of silicone rubber in the fiber material. This demonstrates that PVA has a synergistic effect on the reinforcing properties of silicone rubber.

[0074] Comparative Example 2

[0075] Compared with Example 1, the preparation process of the multifunctional polyester fiber with antiviral and antibacterial properties of traditional Chinese medicine using uncrosslinked hydrogen-containing silicone oil instead of silicone rubber elastomer is the same. The specific preparation steps are as follows:

[0076] (1) Five parts by weight of the antiviral extract of traditional Chinese medicine (water decoction extract of Artemisia argyi, Isatis indigotica, Taraxacum mongolicum, Lonicera japonica, Chrysanthemum indicum and Isatis tinctoria) and 95 parts by weight of PVA aqueous solution (PVA mass concentration of 20%) were heated and stirred to dissolve evenly to obtain a mixed solution.

[0077] (2) Add 100 parts by weight of hydrogen-containing silicone oil (hydrogen content of 0.45%, viscosity of 650 mPa·s at 25℃) to 1000 parts by weight of a mixed solvent of ethanol and isopropanol and stir until dissolved to obtain silicone oil solution.

[0078] (3) The mixture from step (1) and the silicone oil solution from step (2) are heated and stirred to mix evenly at a weight ratio of 1:2. Then, 5% nano silver oxide powder, 3% nano tourmaline negative ion powder and 3% nano far-infrared ceramic powder are added and stirred to mix evenly. The solvent is removed by vacuum drying to obtain PVA-silicone oil composite particles with inorganic functional nanoparticles as the core and coated with antiviral components of traditional Chinese medicine.

[0079] (4) The PVA-silicone oil composite particles with inorganic functional nanoparticles as the core and coated with antiviral components of traditional Chinese medicine obtained in step (3) are added to the extruder at a mass ratio of 12:88 and melt-blended spinning to obtain multifunctional polyester fiber with antiviral, antibacterial and far-infrared negative ions of traditional Chinese medicine.

[0080] The antibacterial, antiviral, far-infrared, negative ion multifunctional polyester fiber material obtained in this comparative example was tested for antibacterial properties, antiviral properties, far-infrared properties, negative ion properties, mechanical strength, and anti-aging properties. The results are shown in Table 4 below.

[0081] Table 4

[0082] Staphylococcus aureus inhibition rate 96％ E. coli inhibition rate 98％ Antiviral activity rate ＞99％ negative ion generation <![CDATA[856 per cm 3 > Far-infrared emissivity 0.87 Fracture strength 5.1 cN / dtex Elongation at break 34％ Strength retention rate 80.4％ Elongation retention rate 82.4％

[0083] As shown in Table 4, compared to Example 1, replacing the silicone rubber elastomer with uncrosslinked hydrogen-containing silicone oil significantly reduced the improvement in mechanical strength and anti-aging properties of the fiber material. This is because uncrosslinked hydrogen-containing silicone oil cannot produce a reinforcing structure and has poor compatibility with both PVA and the fiber material. This manifests as significant oil separation in the PVA-silicone oil composite particles, resulting in poor dispersion within the fiber material and a significant reduction in its mechanical strength.

[0084] Comparative Example 3

[0085] Compared with Example 1, the preparation process of the multifunctional polyester fiber with antiviral and antibacterial properties of traditional Chinese medicine and far-infrared negative ions does not involve the addition of silicone rubber elastomer components, but is otherwise the same. The specific preparation steps are as follows:

[0086] (1) Five parts by weight of the antiviral extract of traditional Chinese medicine (water decoction extract of Artemisia argyi, Isatis indigotica, Taraxacum mongolicum, Lonicera japonica, Chrysanthemum indicum and Isatis tinctoria) and 95 parts by weight of PVA aqueous solution (PVA mass concentration of 20%) were heated and stirred to dissolve evenly to obtain a mixed solution.

[0087] (2) Add 5% nano silver oxide powder, 3% nano tourmaline negative ion powder and 3% nano far-infrared ceramic powder to the mixture in step (1) and stir to mix evenly. Remove the solvent by vacuum drying to obtain PVA particles with inorganic functional nanoparticles as the core and coated with antiviral components of traditional Chinese medicine.

[0088] (3) The PVA particles with inorganic functional nanoparticles as the core and coated with antiviral components of traditional Chinese medicine obtained in step (2) are added to the polyester chips at a mass ratio of 12:88 and then melt-blended and spun to obtain multifunctional polyester fiber with antiviral, antibacterial and far-infrared negative ions of traditional Chinese medicine.

[0089] The antibacterial, antiviral, far-infrared, negative ion multifunctional polyester fiber material obtained in this comparative example was tested for antibacterial properties, antiviral properties, far-infrared properties, negative ion properties, mechanical strength, and anti-aging properties. The results are shown in Table 5 below.

[0090] Table 5

[0091] Staphylococcus aureus inhibition rate 99％ E. coli inhibition rate 99％ Antiviral activity rate ＞99％ negative ion generation <![CDATA[878 per cm 3 > Far-infrared emissivity 0.88 Fracture strength 5.6cN / dtex Elongation at break 32％ Strength retention rate 67.9％ Elongation retention rate 68.8％

[0092] As can be seen from the results in Table 5, compared with Example 1, the absence of silicone rubber elastomer for reinforcement leads to a significant reduction in the mechanical strength and anti-aging properties of the fiber material.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
