Description

TECHNICAL FIELD

[0001] The present application belongs to the field of clothing and bedding filling materials, and relates to an aerogel filling structure without powder falling and vapor permeability and a clothing and bedding made of the aerogel filling structure, in particular, an ultrathin clothing, quilt, sleeping bag, hat and glove containing aerogel. BACKGROUND

[0002] Aerogel is currently known as the best heat insulation performance and the lowest density solid. It can lock a large amount of still air in a small space, has extremely low thermal conductivity and extremely light weight, and has excellent performance as a heat insulation material. However, aerogel is a brittle material and cannot be directly applied to clothing and bedding products that need to be repeatedly bent during use and / or storage. Therefore, aerogel must be made into particles or powder before being attached or wrapped in other substrates for use.

[0003] At present, a large number of companies simply mix aerogel powder into glass fiber mat, non-woven fabric, open-cell foam material or plastic film substrates for application. This scheme of mixing aerogel powder between fiber bundles, open-cell foam structures or film structure substrates has been widely used in aerogel heat insulation materials for walls / pipes that do not need to be repeatedly bent. However, when it is directly used in clothing, quilts, sleeping bags, mattresses and other sitting and lying tools that need to be repeatedly bent and / or washed, a serious aerogel powder falling phenomenon occurs. The falling aerogel powder not only affects the appearance, but also causes human body allergy, cough, sputum, sneezing, itching, eye blur, chest tightness, breathing difficulty, dermatitis, rhinitis and / or other diseases. Long-term use of such aerogel products with powder falling may even cause serious diseases such as pneumoconiosis / silicosis, thus failing to meet the basic safety and aesthetic requirements of clothing and bedding. Moreover, the reduction of aerogel content after powder falling also leads to the reduction of product heat insulation performance, affecting the product quality.

[0004] The main reason for the powder dropping phenomenon of such simple inclusion composite aerogel products is that the aerogel powder particles are simply mixed with the substrate, and there is no stable connection between the two. Once subjected to external force or steam flow impact, the light and fine aerogel powder particles will move freely between the substrates. At this time, if the gap size between the fibers of the fabric wrapping such a composite material is larger than the free-moving aerogel powder particles, these aerogel powder particles will escape from the gap between the fibers of the fabric, resulting in the powder dropping phenomenon. Moreover, the aerogel inclusion layer of these quilted products will generate a large number of sub-millimeter or even millimeter-level penetrating needle holes during the sewing process, and the aerogel particles in the inclusion layer are not restrained, and the aerogel powder will escape from the needle holes like the down running phenomenon of down jackets, resulting in the powder dropping phenomenon. In addition, the movement of the human body will inevitably cause the aerogel inclusion layer to be repeatedly squeezed and decompressed, and the aerogel powder in the inclusion layer will continuously escape from the needle holes with the repeatedly squeezed steam flow. Finally, no matter how the initial particle size of the aerogel powder in the inclusion layer is controlled, since the aerogel is very brittle, the aerogel particles will be crushed into smaller particles due to repeated squeezing and / or impact during use; these crushed aerogel powders not only leak out of the needle holes, but also, after a long period of use, when the particles become small enough, even directly seep out of the gaps between the fabric fibers of these clothing, quilts or sleeping bags and other products without needle holes. Therefore, the existing technical solutions that include aerogel powder as an inclusion layer in even impermeable film structures also have unsatisfactory practicability and / or reliability due to the fear of the penetrating needle holes and powder dropping during the sewing process of the clothing.

[0005] To solve the powder dropping problem, some companies have also tried to directly mix aerogel micro-powder into molten materials such as polyester, spandex and / or aramid to make fibers, then spin the fibers to make clothing and other products. The scheme of mixing aerogel powder into the interior of the fiber filament has extremely low content of aerogel particles that can be mixed into the interior of the fiber filament due to the extremely low density, large specific surface / surface tension and hydrophobic / aphilic properties of aerogel particles, and the maximum mixing ratio known so far is less than 1%, so it cannot fully play the heat preservation and insulation performance of the aerogel component. Moreover, as for such technology, even if the content of aerogel particles in the interior of the spinning filament (not between the spinning filaments) can be improved in the future, the strength of the spinning filament and the fiber will be severely reduced due to the inherent characteristics of the extremely brittle and aphobic nature of aerogel particles, and there will be great problems in spinnability and fiber strength, so the feasibility and practicability of such technology will not be strong.

[0006] Currently, some companies also directly mix aerogel powder into closed-cell foam materials and / or closed-cell film materials.

[0007] Such technical solutions not only face the same problems of difficulty in mixing aerogel powder into closed-cell structure at a high proportion, serious chemical odor of foamed products, and obvious decline in thermal insulation capacity of foamed materials after extrusion, compression, collision or sitting, but also must be made into a closed-cell substrate to prevent product powder from falling off, which leads to poor vapor permeability, stuffiness, easy to cause allergies, and poor skin adaptability. There are several aerogel clothes on the market based on the composite of aerogel powder into closed-cell foamed materials, which all have the problems of poor vapor permeability and too small aerogel content leading to the effect of thermal insulation and cold prevention far below the promotional effect. When the product is placed on an electron microscope, the main structure is still the conventional foaming structure, and the aerogel powder is only a secondary material for decoration. The reason is understandable: the volume of foamed material before and after foaming is very different, and the volume after foaming generally expands to tens to hundreds of times of the volume before foaming, generally 40-60 times. However, aerogel material is not expandable, and after foaming, it is equivalent to being diluted by 40-60 times, or even hundreds of times. Its main structure is not aerogel material at all. Therefore, when searching the website baidu.com with the keyword "aerogel clothing", the system automatically jumps out the highest frequency of the searched keyword "aerogel clothing scam", which is a regrettable result.

[0008] There are even companies such as ZEROLOFT (http: / / zeroloft.com) and AEROTHREM (www.aerotherminsulation.com) under the original ASPEN SYSTEM company in the United States and AGEL TECHNOLOGY (www.agel-tech.com) in Shenzhen, China, which seal aerogel powder into flat film capsules of different sizes and shapes with plastic film, aluminum film or other airtight materials, and then fix them to some positions of the clothing like wearing armor or applying plaster.

[0009] Such technical solutions are not ideal in terms of heat preservation effect due to limited coverage or discontinuous coverage area, and the flat film capsule body containing aerogel powder is also very afraid of needle and thread holes, so its practicality is not strong. After the flat film capsule is punctured during use, cleaning, storage or transportation or cracks due to natural aging, a large amount of aerogel powder will be leaked out at once or chronically, which will pose a serious safety hazard and health threat to the respiratory system and skin of consumers. For this reason, these products have not been widely accepted by the market after being promoted by CHAMPION (HANESBRANDS), ELEMENT 21, RUSSELLOUTDOORS and other companies for many years. If a large area of fully enclosed material is used to manufacture flat film capsules containing aerogel for clothing interlayers, although the powder leakage phenomenon can be overcome, the clothing product will have no vapor permeability, be hot and sweaty, and have poor use effect; and the serious safety hazards such as powder leakage after long-term use or accidental puncture cannot be overcome.

[0010] All the above existing aerogel clothing technical solutions are trying to use the excellent thermal insulation performance of aerogel to make extremely thin textile materials or sandwich, which is certainly a worthwhile direction; However, it ignores an important problem: there will always be more or less air layer between the human skin and these extremely thin textile materials or sandwich; Especially there are a large number of concave and convex curved structures such as human physiological curvature, trunk cross-section depression, joint curved surface and so on in the human body. The space formed by the natural sagging of these concave and convex curved structures and the extremely thin fabric or sandwich results in that they cannot be closely attached to the human body, resulting in a large amount of free air layer. These free air layers not only have strong convective heat dissipation capacity, but also, due to the squeezing of the human body to these spaces, the hot air in them will be continuously squeezed out to the outside, and at the same time, due to the stretching of the outer fabric and / or sandwich after the squeezing of these spaces, cold air from the outside will be sucked into these spaces, resulting in the continuous emission of hot air and the continuous suction of cold air in these spaces, which will be continuously replaced with the movement of the human body, and the thermal insulation effect will naturally be greatly reduced. The main reason for the complaints of several brands of aerogel clothing by a large number of consumers as "poor thermal insulation effect" or even "aerogel clothing scam" is here: when simply measuring the thermal conductivity, thermal resistance, cro value or thermal insulation rate of these aerogel clothing sandwich, its thermal insulation effect is good (even excellent), but when it is made into a finished clothing and worn by consumers, consumers cannot feel the good or excellent thermal insulation performance of these sandwich, which leads to a large number of complaints. Therefore, if the free air layer or free air space can be reduced or eliminated, the air convection and conduction in these spaces can be reduced or eliminated, especially the continuous exchange of hot air in these spaces and cold air from the outside can be reduced or eliminated, the final actual thermal insulation effect of these aerogel clothing can be significantly improved. Due to the extremely thin characteristics of the extremely thin textile material or sandwich, the effect of eliminating or reducing the free air in such concave and convex curved structures is not ideal; But if such extremely thin textile material or sandwich is replaced by a filling structure with a certain thickness, because the filler naturally has a certain loft, throw and expansion capacity, the free space in such concave and convex curved structure or free sagging structure will be occupied by the filler or the continuous fabric pressed by it, which can reduce or even eliminate the free air layer, inhibit or eliminate the exchange of cold and hot air and the convection and conduction of hot air, and greatly improve the thermal insulation performance of the final clothing product.

[0011] Therefore, it is a valuable research direction to adjust the research and development direction of aerogel thermal insulation clothing from "research and development of extremely thin fabric or interlayer" to "research and development of aerogel clothing filling material with a certain thickness" (since the aerogel component has excellent thermal insulation capacity, the thickness of the new filling material will be much smaller than that of the conventional filling material); and as a discrete filling material, the natural vapor transmission gap and vapor transmission space between the filling components can also solve the important problem of vapor permeability in the clothing field.

[0012] Therefore, the development of an aerogel filling structure that can utilize the excellent thermal insulation performance of aerogel, prevent aerogel powder from falling off or seeping out of the product, be vapor permeable, and eliminate or reduce the free air layer in the existing aerogel clothing fabric and / or interlayer, as well as the clothing and bedding made therefrom, is a technical problem that needs to be solved by those skilled in the art. SUMMARY

[0013] The purpose of the present application is to develop an aerogel filling material that can utilize the excellent thermal insulation performance of aerogel, be vapor permeable, reduce or eliminate the free air layer in the clothing, and prevent aerogel powder from falling off or seeping out of the product.

[0014] In order to achieve the above-mentioned purpose of the present application, the following technical solutions are adopted:

[0015] An aerogel filling structure for clothing, comprising: a vapor-permeable fabric and / or a vapor-permeable film and aerogel large particle monomers and / or aerogel small particle aggregates;

[0016] The aerogel large particle monomers comprise aerogel large particles and a wrapping layer wrapped around the aerogel large particles;

[0017] The aerogel small particle aggregates are formed by linking aerogel small particles through a mixture of one or more of a bonding agent, an adhesive, a structural adhesive, a curing agent, a cross-linking agent, and a coupling agent;

[0018] The vapor-permeable fabric and / or the vapor-permeable film completely wrap the plurality of aerogel large particle monomers and / or aerogel small particle aggregates, and the size of the aerogel large particle monomers and / or the aerogel small particle aggregates is greater than the size of the vapor transmission gap and the needle hole of the vapor-permeable fabric and / or the vapor-permeable film;

[0019] The size of the aerogel large particle monomers and the aerogel small particle aggregates ranges from 0.1 microns to 2.5 centimeters, preferably 0.6-1 millimeters.

[0020] The beneficial effects of the above technical solutions are: the aerogel particles are aerogel large particles with a wrapping layer, or the aerogel small particles in the aerogel small particle aggregates are tightly bonded together to become a whole and will not easily scatter; the moisture vapor emitted by the human body can easily pass through the vapor transmission gaps on the vapor transmission fabric and / or vapor transmission film, the gaps between the fiber filaments and / or fiber bundles, and the inter-particle vapor transmission gaps between the aerogel large particle monomers and / or aerogel small particle aggregates, and the minimum size of the aerogel large particle monomers and / or aerogel small particle aggregates is larger than the size of the vapor transmission gaps on the vapor transmission fabric and / or vapor transmission film and the needle and thread holes (if any), so the aerogel powder particles cannot leak out of the vapor transmission gaps on the vapor transmission fabric and / or vapor transmission film and the needle and thread holes. Moreover, the aerogel large particle monomers are provided with a wrapping layer, and the aerogel small particles are tightly connected to each other by the adhesive to become aerogel small particle aggregates that will not easily scatter, so these aerogel products are not easily crushed during repeated folding. The aerogel small particles that make up the aerogel small particle aggregates are firmly defined / fixed together by the adhesive and cannot be further crushed (for example, to obtain nanoscale aerogel small particles bonded into micrometer or millimeter level aerogel small particle aggregates by a special grinding process, the deformation range of the aerogel small particle aggregates under pressure is several thousand times, several ten thousand times, or even several hundred thousand times of the nanoscale small particles; the pressure on the nanoscale small particles in such a large deformation range is not enough to crush them), these aerogel particles can also be stably attached or defined in conventional filler materials, and the aerogel powder can be very firmly bonded or sealed in the modified filler material by a multi-level fixing structure, and it is not easy to fall out or fall off, so there will be no powder falling phenomenon. Moreover, even if some of the aerogel large particles 1 are crushed in the long-term process, the wrapping layer provided outside the aerogel large particle monomers can still enclose these crushed aerogel small particles (powder) in the wrapping layer to become another form of aerogel small particle aggregates that will not easily scatter (that is: this crushed aerogel small particle aggregate is a small particle in the wrapping layer that can move relatively but cannot scatter, while the small particles in the aforementioned small particle aggregates are fixed by the adhesive and cannot scatter, and even if the small particles are fixed and then a wrapping layer is provided outside the aggregates, it is more difficult to scatter; both forms of aerogel particles cannot leak out of the gaps smaller than them). This is the most obvious advantage of the "aerogel particles selected by bonding and / or wrapping layer and particle size" scheme in the present application over the "simple and direct mixing of conventional aerogel particles in the base material" scheme.

[0021] Moreover, the above preferred 0.6-1 millimeter aerogel particles that are properly coated or bonded, have a size that is less than or close to the diameter of a sewing needle. During the sewing process, such particles with a size that is less than or close to the diameter of a sewing needle will be pushed aside by the needle and are less likely to be punctured by the needle. Nonetheless:

[0022] As for the small aerogel particle aggregates, because the adhesive can be selected to have a very high bonding strength, even if a small number of aggregates are broken open by the sewing needle, the broken aggregates will only be partially broken open and the size of the broken pieces will still be larger than the size of the fabric vapor permeation voids and the needle thread holes, and will not fall out. Even if there are extremely small pieces, because the size of these extremely small pieces is still smaller than the size of the needle thread holes, the nanoscale aerogel powder will not easily float in the air but will directly fall to the ground as the extremely small pieces are still micron-scale particles that are fixed by the binder on the other filler fibers. Thus, the amount of these possible leaks will not only be far below the safety standard, but the weight of the leaks will also be controlled to fall vertically to the ground rather than floating in the air and being inhaled by the consumer to pose a health threat.

[0023] As for the large aerogel particle aggregates, even if a very small number of large particles are broken open by the sewing needle, the amount will be far below the safety standard and will not pose a health threat to the consumer. Furthermore, if the filler used contains large aerogel particles, these extremely small amounts of leaks caused by the needle puncture can be removed by a conventional blowing process after the sewing is completed, which can remove the conventional dust in the clothing production as well.

[0024] To facilitate production, reduce costs, and further control the risk of falling powder, it is preferred to use small aerogel particle aggregates with an adhesive.

[0025] Further, the above-mentioned aerogel-filled structure for clothing further comprises: fibers, foamed materials, glass microbeads, and / or functional materials;

[0026] The fibers, foamed materials, glass microbeads, and / or functional materials are filled between the vapor-permeable fabric and / or membrane and the large aerogel particle monomers and / or small aerogel particle aggregates, and the large aerogel particle monomers and / or small aerogel particle aggregates are bonded within or on the surface of the fibers, foamed materials, glass microbeads, and / or functional materials by a mixture of one or more of a structural adhesive, a bonding / adhesive agent, a curing agent, a cross-linking agent, and a coupling agent.

[0027] Further, the above-mentioned fibers are one or a mixture of cotton, wool, cashmere, hemp, polyester staple, polyester filament, spandex filament, and aramid fiber.

[0028] The beneficial effects of the above preferred technical solutions are: filling the above materials can reduce the amount of aerogel filling, reduce costs, and also make full use of the physical or chemical properties of these materials. For example, the high elasticity of spandex fibers, the high strength of aramid fibers, the low cost of polyester filaments, and the skin-friendly nature of cotton and hemp fibers can improve the overall performance of the aerogel filled clothing products of the present application.

[0029] Further, the aerogel large particle monomers and / or aerogel small particle aggregates are aqueous silica aerogel, aqueous titanium dioxide aerogel, aqueous carbon aerogel or aqueous polyimide aerogel.

[0030] Further, the vapor-permeable fabric or vapor-permeable film includes two layers, the first layer of vapor-permeable fabric or vapor-permeable film completely wraps the plurality of aerogel large particle monomers and / or aerogel small particle aggregates to form a layered or clumped structure, and the second layer of vapor-permeable fabric or vapor-permeable film is wrapped on the surface of the layered or clumped structure.

[0031] And / or, a wrapping layer is further provided on the surface of the layered or clumped structure and / or vapor-permeable film or vapor-permeable fabric.

[0032] Further, the aerogel filled clothing structure described above further comprises:

[0033] High-heat reflectivity material or far-infrared material, the surface of the layered or clumped structure is wrapped with high-heat reflectivity material or far-infrared material.

[0034] Further, the wrapping layer is an organic wrapping layer and / or an inorganic wrapping layer.

[0035] The organic wrapping layer material is one or a mixture of several of structural glue, adhesive, curing agent, crosslinking agent, coupling agent;

[0036] The inorganic wrapping layer material is one or a mixture of several of silica film, ceramic film, metal film, zeolite film, glass film and / or molecular sieve composite film.

[0037] Further, the adhesive is any one or a mixture of several of water-based pure acrylic emulsion, water-based vinyl acrylic emulsion, water-based styrene acrylic emulsion, water-based acrylate emulsion, water-based polyurethane emulsion, water-based epoxy resin emulsion, water-based silicone emulsion.

[0038] Further, the functional material is high-heat reflectivity material, and / or far-infrared material, and / or moisture-absorbing and heat-generating material, and / or phase change material.

[0039] The beneficial effect of the preferred technical scheme is that the overall heat preservation performance of the final product can be further improved, the moisture-absorbing and heat-generating material can absorb the moisture emitted by the human skin to generate heat, and the human body wrapped therein can obtain an additional heat source, so that the human body can obtain more heat more quickly.

[0040] Further, the high-heat reflectivity material is aluminum powder or aluminum film, and the far-infrared material is far-infrared fiber.

[0041] The beneficial effect of the preferred technical scheme is that the overall heat preservation performance of the final product can be further improved, the moisture-absorbing and heat-generating material can absorb the moisture emitted by the human skin to generate heat, and the human body wrapped therein can obtain an additional heat source, so that the human body can obtain more heat more quickly.

[0042] Further, the aerogel clothing and bedding further comprises an electric heating device, a temperature sensor and / or a temperature control device. The inner side or the outer side of the fabric of the aerogel clothing and bedding is provided with the electric heating device, the temperature sensor and / or the temperature control device.

[0043] The beneficial effect of the further technical scheme is that the electric heating device is provided on the inner side or the outer side of the fabric of the aerogel clothing and bedding, which greatly improves the heat insulation performance and also obtains an additional heat source other than the body temperature, so that the human body wrapped therein can obtain more and faster temperature rise and less temperature loss, and is especially suitable for use in extreme environments such as polar regions and high mountains. In addition, the temperature sensor and the temperature control device can be used to accurately control the temperature in the filling material, like the battery heating clothes that are popular now.

[0044] Further, the vapor-permeable fabric is any one or a mixture, splicing and / or superposition of several of polyester fabric, nylon fabric, spring silk, cotton fabric, linen fabric, non-woven fabric, jacquard sandwich fabric, pull-wire fabric and space layer (air layer).

[0045] The aerogel large particle monomers and the aerogel small particles are any one or a mixture of several of particle shape, small piece shape, short rod shape, fiber shape and flocculent shape. As long as the minimum size of the particle shape, small piece shape, short rod shape, fiber shape and flocculent shape aerogel particles or aggregates is greater than the size of the fabric void or needle hole (if any), the aerogel powder dropping phenomenon can be avoided. Even if the aerogel small particle aggregates are directly made into fiber-shaped or flocculent aerogel aggregates with a wrapping layer, they can be directly used as fillers, reducing the manufacturing process.

[0046] The clothing and bedding aerogel filling structure in the application can be applied in the preparation of clothes, quilts, sleeping bags, hats and / or gloves.

[0047] One of the preparation methods of the aerogel clothing and bedding is as follows:

[0048] The aerogel particles include aerogel large particle monomers and / or small particle aggregates. The preparation method of the aerogel small particle aggregates is to prepare the water-based aerogel slurry by extruding mesh granulation, extruding line / strip multi-channel cutting granulation, repeated cutting granulation after slurry drying or semi-drying, or even the preparation method as described in Chinese Patent No. CN106517219B. The aerogel particles prepared by the above non-patent conventional technology, expired patent technology or published patent technology can be conveniently and cheaply purchased in large quantities on the market, and we can only choose the particle size that meets our requirements.

[0049] After obtaining these aerogel particles with the minimum size greater than the steam permeable gap size and the needle hole size of the fabric, an appropriate amount of the aerogel particles is weighed and filled into a sealed space, the filled aerogel particles are blown into a boiling state by a fan arranged in the sealed space, and then fiber, foaming material and / or functional material are blown into the sealed space, or a spraying or adhering wrapping layer is sprayed or adhered to the boiling aerogel particles; thus, the aerogel filling material of the present application is prepared; and the aerogel filling material can be further made into a layered or lump structure, and a spraying or adhering wrapping layer is sprayed or adhered to the surface of the layered or lump structure, so as to further fix the aerogel particles, and the aerogel filling material of the present application is prepared. The aerogel filling material of the present application is filled into a filling capsule made of steam permeable fabric and / or steam permeable film or is further cut and processed to prepare a super warm or ultra-thin clothing and bedding containing aerogel.

[0050] The present application has the following beneficial effects:

[0051] The most obvious advantage of the present application is that the aerogel macro-particles are confined / fixed by the outer wrapping layer (even if they are further crushed, the fragments will not fall out of the wrapping layer), and / or the aerogel micro-particles that form the aggregates are firmly confined / fixed together and will not be further crushed (for example, to obtain nanoscale aerogel micro-particles by special grinding process, the deformation range of the aggregate under pressure is several thousand times, several ten thousand times or even several hundred thousand times of the nanoscale micro-particles; the pressure dispersed on the nanoscale micro-particles in such a large deformation range is not enough to crush it, but only causes certain overall deformation of the micro-particle aggregate, and these deformations are recoverable or have no substantial effect on the macro-scale finished product). Moreover, these aerogel particles can be stably attached or confined in conventional filling materials, and aerogel powder can be very firmly bonded or sealed in the modified filling material through multi-level fixed structures, and is not easy to fall out or drop, and does not have the problem of falling powder; it can avoid the problem of allergy, throat itching and other serious quality problems and safety hazards caused by the inhalation of aerogel falling powder by the human body, and can also avoid the problem of poor thermal insulation performance caused by the reduction of aerogel, and improve the use effect and service life of the filling material.

[0052] The present application makes full use of the excellent thermal insulation performance of aerogel, and can obtain much better thermal insulation effect than conventional filling materials. To obtain the same thermal insulation capacity, the weight and / or volume of aerogel required by the modified filling material of the present application is much lower than that of conventional filling products with the same thermal insulation performance. Compared with conventional filling materials, the total weight and storage volume of the modified filling material of the present application can be significantly reduced, and the use amount of filling can also be reduced, and the same or even better thermal insulation capacity can be easily obtained as thick traditional filling products, and many ultra-thin and / or ultra-light filling products can be made, which not only provides better thermal insulation effect, but also makes the product lighter, thinner, smaller in storage volume and more convenient to wear and use, especially can perfectly overcome the problem of obesity of traditional clothing products with filling, so that the user can maintain a slim figure and agile movement in cold weather, especially suitable for women who love beauty and outdoor activity participants who require high mobility.

[0053] The development direction of aerogel thermal insulation clothing is changed from the known technical solutions of "developing extremely thin fabric or interlayer" to "developing aerogel clothing filling material with a certain thickness (as the aerogel component has excellent thermal insulation ability, the thickness of the new filling material will be much smaller than that of conventional filling materials)". The finished product can be adjusted from 0.5mm, 1mm or 2-3mm of the above known product to about 2-30mm (preferably 2-9mm) without significantly affecting the performance of the clothing, reducing or eliminating the free air layer or free air space in the clothing and its interlayer, reducing or even eliminating the air convection in these spaces and the continuous exchange of hot air in these spaces with the outside cold air, which can significantly improve the final actual thermal insulation effect of the aerogel clothing. The known technical solutions of 2mm, 1mm or even 0.5mm of such extremely thin textile material or interlayer due to its own extremely thin characteristics, the effect of eliminating or reducing the free air in the concave-convex curved structure of the human body after being suspended and supported is not ideal; but in this invention, such extremely thin textile material or interlayer is replaced by a filling structure with a certain thickness, and due to the natural porosity, loft and expansion ability of the filler, the free space in such concave-convex curved structure or free hanging structure will be occupied by the filler or the continuous cloth under the pressure of the filler, so as to reduce or even eliminate the free air layer, inhibit or even eliminate the exchange of cold and hot air and the convection and conduction of hot air, and greatly improve the thermal insulation performance of the final clothing product.

[0054] In addition, the above-mentioned aerogel clothing bedding has good vapor permeability because there are a large number of through-type voids between the filled substrates, between the aerogel large particle monomers and / or aerogel small particle aggregates, and between the substrates and the aerogel large particle monomers and / or aerogel small particle aggregates. This is obviously superior to the existing technical solutions in the market that make aerogel into a vapor-impermeable interlayer, and can overcome the problem of low aerogel content and poor thermal insulation effect in these technical solutions. In addition, by setting a wrapping layer outside the aerogel particles or bonding the aerogel small particles into aerogel small particle aggregates that will not easily separate, the main process is a simple aerogel physical mixing or adhesion process, which is much lower in manufacturing cost and process difficulty compared to the complex chemical process of wrapping aerogel powder into closed-cell foam structure, and is more suitable for commercialization and large-scale promotion. To put it another way, without considering the manufacturing cost and aerogel content, even the existing vapor-impermeable interlayer with aerogel in the market can be cut or broken into particles or sheet fillings with a particle size greater than the gap between the fabric fibers and the needle holes, and then filled into the filling bag made of fabric, to achieve vapor permeability (because the vapor-impermeable interlayer is cut or broken into many particle or sheet fillings, which can produce a large number of vapor-permeable voids between them) and no powder loss (because the aerogel powder of these products is confined in the closed-cell foam structure). However, considering reducing manufacturing costs, reducing processes and increasing aerogel content, the technical solution of directly mixing the aerogel particles that will not lose powder in the traditional filling fibers in the present application is obviously more reasonable, cheaper, more feasible and more reliable.

[0055] In addition, as various conventional fibers with good tensile, folding and pressure strength, they can become good substrates for attaching or wrapping the above-mentioned aerogel powder particles, and the finished products made of them can have very obvious improvements in bending, flexibility and durability compared to bulk aerogels, meeting the use requirements of clothing and bedding products that will be repeatedly folded, rolled up, squeezed and stored.

[0056] The above-mentioned aerogel clothing bedding has a much greater thermal insulation capacity than conventional non-woven fabrics, cotton, hemp and other natural fibers, polyester, aramid, spandex and / or blended fibers of these materials, so its thermal insulation performance can be greatly improved. In particular, the maximum distance between the naturally stretched fibers can reach several millimeters or even centimeters, so the aerogel powder particles can be easily and abundantly placed inside these substrates. Therefore, the weight ratio of aerogel in the above-mentioned aerogel clothing bedding with stable and reliable performance can easily exceed 1%, and even 99%, that is, the above-mentioned conventional filling substrates can even be used mainly as supporting substrates to maintain the shape of the heat insulation layer rather than as thermal insulation materials.

[0057] Since the heat insulation performance of aerogel plays a major role in the present application, the filler as the base material plays a secondary or even negligible role in heat insulation, so a relatively inferior filler with lower bulkiness and smaller porosity can be used to obtain the same or even much better heat insulation performance. Therefore, the use of a relatively inferior filler can not only reduce costs but also expand the source of raw materials.

[0058] The aerogel filling material described above can be used to make ultra-thin and / or super-cold-weather clothing, ultra-thin and / or super-warm sleeping bags, ultra-thin and / or super-warm underwear, ultra-thin and / or super-warm hats, ultra-thin and / or super-warm gloves, and super-warm shoes, etc. After mixing the required aerogel particles into the above product filling materials, the production of these products is a very mature industry, with stable and reliable production processes and equipment, and the production cost will not increase significantly.

DETAILED DESCRIPTION

[0067] The present application will be further described in detail below with reference to the accompanying drawings and specific examples, which are provided only for the purpose of explanation and are not intended to limit the scope of the present application.

[0068] One specific preparation method of the aerogel filler of the present application is as follows:

[0069] First, aerogel small particle aggregates 10 or aerogel large particle monomers with a wrapping layer 2 are purchased from the market or prepared by oneself. As shown in Figure 2 Even if some of the aerogel large particles 1 are crushed in the long-term process, the wrapping layer 2 outside the aerogel large particle monomers can still enclose these crushed aerogel small particles 8 (powder) in the wrapping layer 2, becoming another form of aerogel small particle aggregates that are not easily dispersed. (That is, the crushed aerogel small particle aggregates are small particles in the wrapping layer that can move relatively but not disperse, while the small particles in the aforementioned small particle aggregates are fixed by adhesives and cannot disperse, and even if they are fixed and then wrapped outside the aggregates, it is more difficult for them to disperse.) As shown in Figure 3 The aerogel small particle aggregates 10 can be firmly bonded by adhesives 9; as shown in Figure 1 The aerogel large particle monomers can form a wrapping layer 2 by uniformly spraying a wrapping liquid on the aerogel large particles 1 and then drying or solidifying. Then, the aerogel small particle aggregates 10 or aerogel large particle monomers are made or sieved into aerogel particles of a certain size (preferably 0.6-1 mm).

[0070] The aerogel large particle monomers and / or aerogel small particle aggregates 10 with a minimum size greater than the size of the vapor-permeable space 4 and the size of the needle hole 5 (the size of the vapor-permeable space of the fabric is generally about 0.01-0.05 mm, and the size of the needle hole is generally about 0.5 mm) on the vapor-permeable fabric and / or vapor-permeable film are poured into the sealed space, and the aerogel large particle monomers and / or aerogel small particle aggregates 10 poured in are blown into a boiling state by a fan arranged in the sealed space, and then Figure 4 fibers 11, foaming materials, and / or other functional materials (for example: Figures 5-6 ceramic or glass microbeads, Figure 6 phase change material microbeads 13) as shown are blown into the sealed space, and after being fully mixed and evenly distributed, the aerogel filler product with super-strong heat preservation capacity in the present application can be obtained by filling the capsules made of the vapor-permeable fabric and / or vapor-permeable film 3.

[0071] Of course, the above fully mixed mixture can be further made into a layered or lump structure, and an adhesive 9, a fixing agent or an adhesion wrapping layer 2 is sprayed on the surface of the layered or lump structure to further and multi-level fix or limit the aerogel particles, so as to obtain a multi-level fixed aerogel filling material in the application, and then the aerogel filling material in the application is filled into a capsule made of a vapor-permeable fabric and / or a vapor-permeable film 3 or is further cut and processed into a sandwich and then is sewn into various clothing and bedding.

[0072] The sealed or semi-sealed space into which the aerogel large particle monomers or aerogel small particle aggregates 10 are blown can use existing machine equipment including a dedusting machine, a glue spraying cotton production line, a down separating box / feather separating machine, a piling machine and / or a down filling machine, which are reliable in performance, easy to operate and good in availability.

[0073] Example 1

[0074] 3 kg of aerogel large particle monomers with a size of 0.6-1 mm are weighed and blown into a sealed piling machine, and polyvinyl acetate fine droplets are sprayed on the rolling aerogel large particle monomers to prepare a wrapping layer, and the thickness of the wrapping layer is controlled to be 3-8 μm. After the wrapping layer is dried or solidified, the prepared aerogel particles with the wrapping layer are filled into a dedusting machine, and the fibers output by the dedusting machine are mixed with the aerogel powder large particle monomers uniformly. A cotton cloth or a polyester cloth with a size of 3-5 square meters and a gap between fibers smaller than the above aerogel large particle monomers is selected, and a quilt cover is sewn. During the sewing process, an appropriate needle number or thread thickness is selected, and the needle number is controlled to be 6 (i.e. 55 in metric number, 022 in English number, and the needle diameter is 0.55 mm) so that the size of the needle and thread holes formed during the sewing process is also smaller than the particle size of the above aerogel powder monomers. Finally, the aerogel large particle monomers with the sprayed wrapping layer and / or other fillers are filled into the quilt cover that has been sewn, and a non-dusting and vapor-permeable aerogel quilt is obtained.

[0075] Example 2

[0076] Droplets of aqueous binder, i.e. aqueous polyurethane emulsion, are dripped onto the hydrophilically modified aerogel small particle powder. Such droplets can be generated in large quantities at one time by means of a drip plate and / or a sprayer. The aqueous binder droplets will bind together the aqueous aerogel small particle powder they come into contact with. The size of the aerogel small particle aggregates that can be bound together can be controlled initially by controlling the size of the droplets, i.e. the total amount of binder in a unit droplet. After the aerogel small particle aggregates have been cured or dried, they are subjected to a number of collisions by means of a strong blast or blowing to a state of strong ebullition, in order to separate those aerogel small particles that are not firmly bound together. The aerogel small particle aggregates of the desired size are then separated by means of a pneumatic and / or vibrating sieve. The fraction that passes through the sieve is used as the aerogel filling in the present application, while the fraction that does not pass through the sieve can be returned to the droplet dripping process and participate in the formation of small particle aggregates together with the newly added aerogel small particles until the particle size formed is large enough to pass through the sieve.

[0077] 1.5 kg of the aerogel small particle aggregates having a size of 0.6-1 mm are weighed out and fed into a fluffing machine. The fibers fluffed by the fluffing machine are mixed uniformly with the aerogel small particle aggregates. The aerogel quilted filling product is formed into a planar layer, and a fixing agent having a thickness of 3-8 μm is sprayed onto the surface of the planar layer of the aerogel quilted filling material, in order to further fix the aerogel powder particles.

[0078] Clothing having a gap between the fibers that is smaller than the aerogel powder aggregates is selected, and the clothing is sewn together with the planar layer of the filling interlayer to form a cold-weather clothing product.

[0079] The needle size during the sewing process is controlled to be a gauge number of 6, so that the size of the needle and thread holes formed during the sewing process is also smaller than the particle size of the aerogel powder aggregates.

[0080] After the sewing process is completed, another non-dusting and vapor-permeable clothing filling material described in the present application is obtained.

[0081] Example 3

[0082] Take the aerogel slurry purchased from other aerogel material suppliers (such as Shenzhen Zhongning Technology Co., Ltd., Suzhou Tongxuan New Material Co., Ltd., Guangdong Elisheng High-tech Co., Ltd., and other domestic and foreign aerogel material manufacturers), add curing agent, mix evenly and dry and solidify into blocks. Then use a pulverizer or a blender to pulverize the dried and solidified blocks. After pulverization, first pass through a state of violent blowing or blowing to violent boiling to collide with each other multiple times to peel off aerogel small particles that are not firmly combined, and then pass through a pneumatic and / or vibrating screen to screen out aerogel small particle aggregates of a specified size. The screened portion is used to make the aerogel filling portion in the present application, and the underscreened portion can be returned to the previous slurry mixing process to continue to participate in the formation of the aerogel mixed block with newly added slurry until it is again pulverized and the particle size is large enough to become the screened portion.

[0083] Pour the above screened portion (aerogel small particle aggregates) and the cotton or chemical fiber loosened by the cotton loosening machine into the carding machine together, mix the loose fibers output by the carding machine with the aerogel powder large particle monomers and / or small particle aggregates evenly, and then make the above mixture into a planar layer, which can be cut into another kind of non-dusting and vapor-permeable clothing filling material described in the present application.

[0084] Example 4

[0085] Directly pour the screened portion (aerogel powder aggregates) in the above-mentioned Example 2 or Example 3 into the already sewn clothing cover to use as a filling material, which can obtain another kind of non-dusting and vapor-permeable aerogel clothing product described in the present application.

[0086] The filling material of the clothing product is 100% of the screened portion (aerogel powder aggregates) in the above-mentioned Example 2 or Example 3, which has a high content of aerogel components and extremely strong heat preservation and insulation capacity, and can be made into various ultra-thin and / or ultra-light heat preservation and insulation clothing products.

[0087] Example 5

[0088] Take the aerogel particles purchased from other aerogel material suppliers (such as Shenzhen Zhongning Technology Co., Ltd., Suzhou Tongxuan New Material Co., Ltd., Guangdong Elisheng High-tech Co., Ltd., and other domestic and foreign aerogel material manufacturers), and add them to the production process of needle-punched non-woven fabric. The aerogel particles that have been tightly combined are extruded between the non-woven fabric fibers and then needled into felt.

[0089] Further blow off those dispersed particles that are excessively pulverized during the needling process (the blow-off portion can be mixed into the aerogel slurry for recycling).

[0090] Finally, the cotton cloth or skin-friendly spandex cloth is compounded on the upper and lower surfaces of the needle-punched non-woven fabric after the blowing is completed, so as to obtain another aerogel clothing interlayer without powder falling and vapor permeation.

[0091] Example 6

[0092] The aerogel particles with appropriate sizes purchased from other aerogel material suppliers are weighed and uniformly mixed into the spandex and / or acrylic fiber wadding, and the mixture is made into a plane felt, and then the skin-friendly spandex cloth or cotton cloth is compounded on the upper and lower surfaces of the plane felt, so as to obtain the aerogel thermal underwear without powder falling and vapor permeation.

[0093] Example 7

[0094] The aerogel particles with appropriate sizes purchased from other aerogel material suppliers are directly filled into the air layer of the space layer fabric made of the skin-friendly spandex cloth or cotton cloth, and finally all the residual openings of the space layer are closed, so as to obtain another aerogel thermal underwear or diving suit without powder falling and vapor permeation.

[0095] Example 8

[0096] The aerogel particles with particle sizes greater than 1 cm purchased from other aerogel material suppliers are directly filled into the air layer of the large jacquard pull-out interlayer fabric (the fiber pore diameter of the fabric layer is about 1.5 mm) woven by a large circular machine, and finally all the cuts of the large jacquard pull-out interlayer fabric are sewn, so as to obtain the aerogel thermal cushion without powder falling and vapor permeation.

[0097] Example 9

[0098] Figure 4 It is shown that an aerogel small particle aggregate 10 is sewn together with conventional fibers 11 by a sewing thread 6 to form a thermal insulation filling structure of a thermal clothing made of a vapor-permeable fabric and / or a vapor-permeable film 3.

[0099] Example 10

[0100] Figure 5 It is shown that an aerogel large particle 1 monomer is together with ceramic or glass beads 12 to form a thermal clothing with a thermal insulation filling structure made of a vapor-permeable fabric and / or a vapor-permeable film 3. Of course, the size of the ceramic or glass beads 12 shown in the figure is also preferably greater than the vapor-permeable air gap 4 on the vapor-permeable fabric and / or the vapor-permeable film to avoid leakage. If the size of these ceramic or glass beads 12 is smaller than the vapor-permeable air gap 4 on the vapor-permeable fabric and / or the vapor-permeable film in some special cases, it is only necessary to adhere the ceramic or glass beads 12 to each other and / or to the aerogel large particle 1 monomer as widely used in the paint industry.

[0101] The interior of the ceramic or glass microbeads 12 is either vacuum or filled with thin carbon dioxide gas with lower thermal conductivity than air, which cooperates with the aerogel macro-particles 1 monomers in the present application, and the finished product can obtain better thermal insulation effect; especially when the interior of the ceramic or glass microbeads 12 is vacuum.

[0102] Example 11

[0103] Figure 6 The garment is shown as a thermal insulation filling structure composed of aerogel macro-particle 1 monomers, aerogel small particle aggregates 10, fibers 11, ceramic or glass microbeads 12 and phase change material microbeads 13 in the vapor-permeable fabric and / or vapor-permeable film 3. The aerogel macro-particle 1 monomers, aerogel small particle aggregates 10, fibers 11, ceramic or glass microbeads 12 are cooperatively arranged on the side exposed to the outside air, which can obtain excellent thermal insulation effect; the phase change material microbeads 13 are arranged on the side close to the human skin or underwear.

[0104] Of course, the size of the ceramic or glass microbeads 12 and phase change material microbeads 13 shown in the figure is preferably greater than the vapor gap 4 on the vapor-permeable fabric and / or vapor-permeable film to avoid leakage. If the size of these ceramic or glass microbeads 12 or phase change material microbeads 13 is smaller than the vapor gap 4 on the vapor-permeable fabric and / or vapor-permeable film in some special cases, it is only necessary to adhere these adjacent ceramic or glass microbeads 12, phase change material microbeads 13, fibers 11, aerogel macro-particle 1 monomers, aerogel small particle aggregates 10 to each other as widely used in the paint industry.

[0105] The interior of the ceramic or glass microbeads 12 is either vacuum or filled with thin carbon dioxide gas with lower thermal conductivity than air, and the phase change point of the phase change material in the phase change material microbeads 13 is set to 30 or 32 degrees Celsius, which matches the comfortable temperature of human skin. The phase change material in the phase change material microbeads 13 has the characteristic that when the temperature around it is higher than the phase change point, it will absorb heat (phase change heat) from the surrounding environment to change from solid to liquid; when the temperature around it is lower than the phase change point, it will release heat (phase change heat) to the surrounding environment to change from liquid to solid. By selecting appropriate phase change materials, the phase change heat per unit volume or weight can be considerable. The resulting garment cup has particularly good temperature resistance. There are a large number of different patents disclosed for phase change material clothing solutions, which will not be described here.

[0106] If the clothing in the present embodiment is used in a low temperature environment, the phase change material can release a large amount of phase change heat and quickly adjust the temperature near the human skin to the phase change point, so that the human skin can reach and maintain a comfortable temperature more quickly. If the clothing in the present embodiment is used in a high temperature environment (such as outdoor work in the summer under the scorching sun or a steelmaking workshop, etc.), the phase change material can absorb a large amount of phase change heat from the human skin and quickly adjust the temperature near the human skin to the phase change point, so that the human skin can reach and maintain a comfortable temperature more quickly.

[0107] In the present embodiment, the structure composed of the aerogel large particle monomers 1, the aerogel small particle aggregates 10, the fibers 11, the ceramic or glass microbeads 12 together has super strong thermal insulation performance, so that the phase change heat in the phase change material microbeads 13 can only be released to or absorbed from the skin side, but difficult to be released to or absorbed from the external environment side. These materials cooperate with each other, and a clothing product with stronger functionality and better use effect can be obtained.

[0108] The above aerogel large particle monomers or small particle aggregates can be directly purchased on the market or self-made through traditional non-patented technologies (such as the technology of solidifying and crushing the ready-made slurry and then screening in Embodiment 3 above), so that they have good availability and large selection space.

[0109] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
