Description

Technical Field

[0001] This utility model relates to the field of summer quilt technology, and in particular to a moisture-absorbing and cooling summer quilt. Background Technology

[0002] As consumers demand greater comfort in summer bedding, the shortcomings of traditional summer quilts in terms of lasting cooling effect, moisture absorption and breathability, and hygiene are becoming increasingly apparent, specifically manifesting in the following problems:

[0003] 1. Cooling sensation fades quickly: The cooling sensation depends on the ambient temperature difference. It cannot continuously conduct heat from the body surface after the ambient temperature rises at night; 2. Stiff touch: The addition of inorganic cooling particles (such as mica) increases the stiffness of the fabric (bending stiffness increases by 30%-50%), reducing the comfort of the fabric against the skin.

[0004] 2. Pure cotton fabric: Although it has moisture absorption, its evaporation rate is slow (it takes more than 30 minutes for 50% of the moisture to evaporate), which can easily cause a stuffy feeling; ordinary chemical fiber fabric: has a low moisture absorption rate (<50mm / 30s), and the retention of sweat can easily cause stickiness and discomfort.

[0005] 3. The antibacterial agent has weak adhesion to the fiber, and the antibacterial rate drops from 95% to 60% after 10 washes; the coverage is not comprehensive: only the surface layer is antibacterial, and the internal filling layer is still prone to bacterial growth (especially after sweat penetration).

[0006] In conclusion, a moisture-wicking and cooling summer blanket is needed to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the shortcomings of the existing technology, this utility model provides a moisture-absorbing and cooling summer quilt, which aims to solve the above problems.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a moisture-wicking and cooling summer blanket, comprising a top layer fabric, a middle layer fabric, and an inner layer fabric layer laminated sequentially. The middle layer fabric, from the outside to the inside, consists of a first non-woven fabric layer, a composite cotton layer, and a second non-woven fabric layer. The composite cotton layer comprises a first antibacterial silicone-coated cotton layer, a fine silica gel particle layer, and a second antibacterial silicone-coated cotton layer laminated from top to bottom. The hydrophilically modified silica gel particles efficiently adsorb water molecules through surface hydroxyl bonds; the double-layer antibacterial sprayed cotton forms a moisture-wicking gradient channel, preventing moisture backflow; the non-woven fabric skeleton supports and forms a three-dimensional breathable network; the gaps between the silica gel particle layers achieve airflow and humidity balance; the hydrophilic layer of the silica gel particles inhibits bacterial adhesion; and the nano-silver ions in the sprayed cotton continuously release antibacterial active ingredients.

[0009] In one embodiment, both the outer and inner fabrics are cool-feel crepe fabrics treated with water absorption, quick drying, antibacterial, and deodorizing properties. The cool-feel crepe fabric is composed of a blend of nylon, polyester, and spandex fibers.

[0010] Furthermore, the nylon accounts for 90%-94% by mass, the polyester accounts for 5%-7% by mass, and the spandex accounts for 1%-3% by mass.

[0011] Furthermore, the particle size of the fine silica particles in the layer ranges from 0.1 to 1 mm and is uniformly distributed within the composite cotton layer. The surface of the fine silica particles in the fine silica particles layer is coated with a hydrophilic modification layer, the thickness of which is 5-10 μm, and the hydrophilic modification layer is a composite coating of polyethylene glycol and silica.

[0012] Furthermore, the unit area mass of both the first and second nonwoven fabric layers is 15 g / m². 2 .

[0013] Furthermore, the unit area mass of the first antibacterial silicone spray-coated cotton layer, the fine silica gel particle layer, and the second antibacterial silicone spray-coated cotton layer is 30 g / m². 2 .

[0014] Furthermore, the antibacterial agent used in the antibacterial and deodorizing treatment is nano silver ions, with a loading of 0.1%-0.5% of the mass of the cool-feel crepe fabric, and is evenly distributed on the surface of the blended fibers after impregnation and drying.

[0015] Furthermore, the outer fabric, middle fabric, and inner fabric are bonded together into a single structure using hot melt adhesive.

[0016] Furthermore, the hot melt adhesive is a reactive polyurethane hot melt adhesive, with a coating amount of 10-15 g / m². 2 The composite temperature is 120-150℃, and the composite pressure is 0.3-0.5MPa.

[0017] The beneficial effects of this invention are as follows: hydrophilic modified silica particles efficiently adsorb water molecules through surface hydroxyl bonds; double-layer antibacterial spray-bonded cotton forms a moisture-absorbing and water-locking gradient channel to prevent moisture back-seepage; the non-woven fabric skeleton supports and forms a three-dimensional breathable network; the gaps between the silica particle layers achieve air permeability and humidity balance; the hydrophilic layer of the silica particles inhibits bacterial adhesion; nano-silver ions in the spray-bonded cotton continuously release antibacterial active ingredients; and the double-layer spray-bonded cotton sandwiches the silica particles to form an elastic support layer, improving the softness and pressure resistance of the summer quilt. It has certain practical and promotional value. Attached Figure Description

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 , 2 As shown, a moisture-absorbing and cooling summer quilt includes a top layer fabric 1, a middle layer fabric 2, and an inner layer fabric 3, which are sequentially laminated. The middle layer fabric 2 consists of a 15g first non-woven fabric layer 21, a composite cotton layer 22, and a 15g second non-woven fabric layer 23, which are laminated from the outside to the inside. The composite cotton layer 22 includes a 30g first antibacterial silicone spray-bonded cotton layer 221, a 30g fine silicone particle layer 222, and a 30g second antibacterial silicone spray-bonded cotton layer 223, which are laminated from top to bottom.

[0025] In one implementation, both the outer fabric 1 and the inner fabric 3 are cool-feel crepe fabrics that have undergone water absorption, quick drying, antibacterial and deodorizing treatments. The cool-feel crepe fabric is composed of a blend of nylon, polyester and spandex fibers.

[0026] In one embodiment, the water-absorbing and quick-drying treatment of the cool-feeling crepe fabric is achieved through a hydrophilic additive padding process.

[0027] As one implementation method, the composition of the cool-feel crepe fabric is 92% nylon + 6% polyester + 2% spandex.

[0028] In one implementation, the mass percentage of nylon is 92%, the mass percentage of polyester is 6%, and the mass percentage of spandex is 2%.

[0029] In one embodiment, the fine silica particles have a particle size range of 0.5 mm and are uniformly distributed within the composite cotton layer. The surface of the fine silica particles in the fine silica particles layer is coated with a hydrophilic modification layer with a thickness of 7 μm. The hydrophilic modification layer is a composite coating of polyethylene glycol and silica.

[0030] In one embodiment, the unit area mass of both the first nonwoven layer 21 and the second nonwoven layer 23 is 15 g / m². 2 .

[0031] In one embodiment, the fine silicone particle layer 222 has a thermal conductivity of 0.05-0.15 W / (m·K) and is fixed to the first antibacterial silicone sprayed cotton layer 221 and the second antibacterial silicone sprayed cotton layer 223 by a hot pressing process.

[0032] In one embodiment, the unit area mass of the first antibacterial silicone spray-coated cotton layer 221, the fine silica gel particle layer 222, and the second antibacterial silicone spray-coated cotton layer 223 is 30 g / m². 2 .

[0033] In one embodiment, in the first antibacterial silicone-coated cotton layer and the second antibacterial silicone-coated cotton layer, the amount of silicone coating is 4% of the fabric mass.

[0034] As one implementation method, the antibacterial agent used in the antibacterial and deodorizing treatment is nano silver ions, with a loading of 0.3% of the mass of the cool-feeling crepe fabric, and is evenly distributed on the surface of the blended fibers after impregnation and drying.

[0035] In one implementation, the outer fabric 1, the middle fabric 2, and the inner fabric 3 are bonded together as a single structure using hot melt adhesive.

[0036] In one implementation method, the hot melt adhesive is a reactive polyurethane hot melt adhesive, and the coating amount is 13 g / m². 2 The composite temperature is 135℃ and the composite pressure is 0.4MPa.

[0037] The cool-feel crepe fabric, composed of 92% nylon, 6% polyester, and 2% spandex, passed the Q-max value test (0.35W / cm). 2 This formula demonstrates that it significantly improves fiber thermal conductivity (high nylon content) while maintaining elasticity (spandex), outperforming conventional polyester fabrics (comparative example 1Q-max = 0.18); the composite cotton layer structure includes: a fine silica gel particle layer (30g / m²). 2 Sandwiched between two layers of antibacterial spray-bonded cotton, the thermal conductivity test (0.12W / (m·K)) confirmed that it can quickly conduct heat away from the body surface. After being hot-pressed and combined with the spray-bonded cotton layer, the overall breathability of the summer quilt is increased by 40%.

[0038] The surface fabric 1 quickly wicks away moisture; upon contact with the skin, the cooling crepe fabric rapidly absorbs sweat through capillary action (contact angle < 30°), while the nylon fibers' high specific surface area (> 3.5m²) further enhances its effectiveness. 2 / g) accelerates the diffusion of water to the middle layer, and then locks in water through the two gradients of the middle layer fabric. The hydrophilic modified silica particles capture water molecules through surface hydroxyl (-OH) bonds, with an adsorption capacity of 200-300 mg / cm³. 3 Double-layer antibacterial sprayed cotton forms a "moisture absorption-moisture storage" gradient to prevent moisture backflow (backflow rate <5%); the inner fabric undergoes secondary evaporation, and the symmetrical cool-feel crepe structure establishes a humidity difference, driving moisture to evaporate outward (evaporation rate ≥0.3g / min).

[0039] Nano-silver ions (particle size <20nm) penetrate the bacterial cell wall and inhibit respiratory chain enzyme activity (sterilization rate >99.9%); the hydrophilic layer of silica particles forms a hydration film, hindering bacterial adhesion (adhesion amount reduced by 78%); the slow-release design of silver ions in the spray-bonded cotton ensures an antibacterial rate >90% after 50 washes (AATCC 100 standard).

[0040] After the body heat is conducted to the middle layer 2 through the surface fabric 1, the fine silicone particles absorb some of the heat (latent heat effect of phase change), which slows down the diffusion of heat into the quilt. At the same time, sweat vapor enters the middle layer through the micropores of the non-woven fabric, is adsorbed by the hydrophilic modified silicone particles and gradually evaporates, keeping the inside of the quilt dry. When the ambient temperature drops at night, the silicone particles release the stored heat to prevent the body from feeling too cold.

[0041] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not intended to impose additional limitations on the content of this utility model; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Furthermore, the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
