Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and in particular to a composite curtain. Background Technology

[0002] Curtains, as an indispensable product in home and commercial spaces, not only serve to decorate the space but also play an important role in light regulation, temperature control, and environmental health. As people's quality of life improves, their functional requirements for curtains are becoming increasingly diversified, and traditional single-function curtains are gradually failing to meet practical needs.

[0003] Currently, most blackout curtains on the market are designed to effectively block light by using high-density fabrics, coatings, or multiple layers, making them suitable for bedrooms, home theaters, and other spaces with high light-blocking requirements. However, these blackout curtains have significant functional limitations: to ensure their light-blocking effect, they are usually made of heavy synthetic fibers. These materials have high thermal conductivity and cannot form an effective heat insulation barrier. This makes it difficult to prevent high outdoor temperatures from entering the room in summer, and easy for indoor heat to escape in winter, significantly affecting the comfort of the indoor environment. At the same time, due to the dense fabric structure and lack of targeted antibacterial treatment, mold, mites, and other microorganisms can easily grow in humid environments, affecting indoor air quality and posing a potential threat to human health.

[0004] Another mainstream type of ordinary fabric curtains, thanks to the texture and rich patterns of natural fibers such as cotton, linen, and silk, have a significant advantage in terms of decoration and can be matched with different decorating styles. However, this type of curtain has a significant shortcoming in terms of functionality: the porous structure of natural fibers makes their light-blocking performance poor. Even after dyeing, their ability to block strong light and ultraviolet rays is still limited. Long-term use can lead to problems such as fading and aging of indoor furniture and fabrics due to ultraviolet radiation. In addition, the heat insulation performance of fabrics is also insufficient. Heat can be freely conducted through the gaps between fibers, making it impossible to form an effective temperature difference between indoors and outdoors, and making it difficult to maintain a comfortable indoor temperature during seasonal changes.

[0005] In the existing technology, in order to meet diverse needs, some users adopt the method of using multiple layers of curtains in combination, such as installing blackout curtains and fabric curtains at the same time. However, this method not only increases the installation cost and space occupation, but also makes the opening and closing of the curtains more cumbersome and reduces the ease of use.

[0036] Please see Figure 1-6 The present invention provides a technical solution: a composite curtain, including a curtain body 1, which is composed of a decorative layer 11, a light-blocking layer 12 and an antibacterial layer 13;

[0037] The decorative layer 11, the light-shielding layer 12, and the antibacterial layer 13 are connected together by ultrasonic composite technology.

[0038] The upper end of the curtain body 1 is fixedly connected to the upper bushing 3, and the lower end of the curtain body 1 is fixedly connected to the lower bushing 4.

[0039] Magnet positioning blocks 2 are fixedly connected to both sides of the curtain body 1, and a sliding ring 5 is embedded on the curtain body 1.

[0040] The magnetic positioning block 2 allows the curtain to be magnetically attached to the window frame, thus ensuring its light-blocking effect. At the same time, adjacent curtains can be better closed to prevent light leakage from gaps.

[0041] The light-shielding layer 12 is composed of a high-density light-shielding base fabric 121, a nano-light-shielding coating 122, and a micro-airbag heat insulation layer 123.

[0042] A nano-light-shielding coating 122 is applied to the inner surface of a high-density light-shielding base fabric 121, and a micro-airbag heat insulation layer 123 is disposed on the side of the nano-light-shielding coating 122 away from the high-density light-shielding base fabric 121.

[0043] High-density light-blocking base fabric 121: It is made of polyester filament (80D) and nylon fiber (70D) blended in a ratio of 6:4, woven on a water jet loom, with the yarn density controlled at 650 yarns / 10cm (350 yarns in the warp and 300 yarns in the weft). After weaving, it is set (180℃, 30 seconds) to ensure the flatness of the base fabric.

[0044] Nano-shielding coating 122: Titanium dioxide (particle size 30nm) and carbon black (particle size 20nm) are mixed in a 3:1 ratio, and water-based acrylic resin (solid content 40%) is added to make a coating slurry (solid content 25%). The slurry is then uniformly coated on the inner surface of the high-density light-shielding base fabric 121 using a doctor blade coater. The coating thickness is 0.04mm. The slurry is then dried at 100℃ for 3 minutes to form a light-shielding coating.

[0045] Micro-airbag heat insulation layer 123: Polyvinyl alcohol microspheres (50μm in diameter, 80% hollowness) are mixed with water-based adhesive (30% solid content) and coated onto the surface of nano-light-shielding coating 122 by spraying process. The coating thickness is 0.15mm. After drying at 80℃ for 2 minutes, a heat insulation layer containing still air is formed.

[0046] Antibacterial layer 13: Bamboo fiber (30%) and polyester fiber (70%) are mixed and spun into yarn (32 count), woven into fabric, and then subjected to antibacterial treatment: the fabric is immersed in a 2% concentration chitosan quaternary ammonium salt antibacterial agent solution (bath ratio 1:20), with a padding pressure of 0.3MPa and a roll-off rate of 80%, and then baked at 120℃ for 3 minutes to allow the antibacterial agent to crosslink and solidify with the fiber;

[0047] Decorative layer 11: Polyester fiber (70%) and PTFE membrane (30%) are hot-pressed together to form a stain-resistant and wear-resistant fabric. The thickness of the PTFE membrane is 0.01mm, the hot-pressing temperature is 120℃, the pressure is 0.2MPa, and the holding time is 30 seconds to ensure that the PTFE membrane is evenly attached to the surface of the polyester fiber to form a waterproof and stain-resistant barrier.

[0048] The upper bushing 3 is internally fixedly connected with a silicone strip 31;

[0049] The silicone strip 31 (rectangular cross-section, 2cm long, 0.5cm wide, and weighing 50g / m) is embedded into the pre-set upper bushing 3 at the top of the curtain body 1. The bushing is fixed by the overlocking process to ensure that the silicone strip 31 is flat and wrinkle-free, so that the top of the curtain can fit tightly against the upper edge of the window frame.

[0050] The lower bushing 4 is equipped with a counterweight 41 inside;

[0051] A long strip of fabric bag (2cm wide) is sewn at the bottom of the curtain body 1 to form the lower lining 4. Lead weights (total weight 120g / m) are placed inside. Zippers are set at both ends of the fabric bag. The weight can be adjusted by adding or removing lead weights to ensure that the bottom of the curtain hangs down naturally.

[0052] The inner wall of the sliding ring 5 is provided with a telescopic hole 51, and a support rod 52 is slidably connected inside the telescopic hole 51. A ball bearing 53 is rotatably connected to one end of the support rod 52.

[0053] A spring 54 is fixedly connected inside the telescopic hole 51, and the other end of the spring 54 is fixedly connected to the support rod 52.

[0054] When the curtain body 1 needs to be installed, it can be fitted onto the curtain frame through the sliding ring 5. At this time, the ball bearing 53 is in contact with the surface of the curtain frame, and under the action of the spring 54, it is in contact with the curtain frame. Therefore, after the curtain is pulled, it is less likely to move randomly, thus ensuring the positioning effect of the curtain during use, allowing it to stop at a designated position at will. At the same time, the setting of the ball bearing 53 reduces the friction between the sliding ring 5 and the curtain frame, making the curtain body 1 smoother during the pulling process.

[0055] Working principle: High-density light-blocking base fabric 121: It is made of polyester filament (80D) and nylon fiber (70D) blended in a ratio of 6:4, woven on a water jet loom, with the yarn density controlled at 650 yarns / 10cm (350 yarns in the warp and 300 yarns in the weft). After weaving, it is set (180℃, 30 seconds) to ensure the flatness of the base fabric.

[0056] Nano-shielding coating 122: Titanium dioxide (particle size 30nm) and carbon black (particle size 20nm) are mixed in a 3:1 ratio, and water-based acrylic resin (solid content 40%) is added to make a coating slurry (solid content 25%). The slurry is then uniformly coated on the inner surface of the high-density light-shielding base fabric 121 using a doctor blade coater. The coating thickness is 0.04mm. The slurry is then dried at 100℃ for 3 minutes to form a light-shielding coating.

[0057] Micro-airbag heat insulation layer 123: Polyvinyl alcohol microspheres (50μm in diameter, 80% hollowness) are mixed with water-based adhesive (30% solid content) and coated onto the surface of nano-light-shielding coating 122 by spraying process. The coating thickness is 0.15mm. After drying at 80℃ for 2 minutes, a heat insulation layer containing still air is formed.

[0058] Antibacterial layer 13: Bamboo fiber (30%) and polyester fiber (70%) are mixed and spun into yarn (32 count), woven into fabric, and then subjected to antibacterial treatment: the fabric is immersed in a 2% concentration chitosan quaternary ammonium salt antibacterial agent solution (bath ratio 1:20), with a padding pressure of 0.3MPa and a roll-off rate of 80%, and then baked at 120℃ for 3 minutes to allow the antibacterial agent to crosslink and solidify with the fiber;

[0059] Decorative layer 11: Polyester fiber (70%) and PTFE membrane (30%) are hot-pressed together to form a stain-resistant and wear-resistant fabric. The thickness of the PTFE membrane is 0.01mm, the hot-pressing temperature is 120℃, the pressure is 0.2MPa, and the holding time is 30 seconds to ensure that the PTFE membrane is evenly attached to the surface of the polyester fiber to form a waterproof and stain-resistant barrier.

[0060] Structural Description:

[0061] Curtain Body 1: This is the core part of the curtain, consisting of a decorative layer 11, a light-blocking layer 12, and an antibacterial layer 13 connected together using ultrasonic composite technology. The three layers work together to ensure the basic functions of the curtain while also providing it with decorative, light-blocking, heat-insulating, and antibacterial properties.

[0062] Decorative layer 11: Made of polyester fiber (70%) and PTFE membrane (30%) through hot pressing to form a stain-resistant and wear-resistant fabric. The PTFE membrane is 0.01mm thick, the hot pressing temperature is 120℃, the pressure is 0.2MPa, and the holding time is 30 seconds. This ensures that the PTFE membrane is evenly attached to the surface of the polyester fiber, forming a waterproof and stain-resistant barrier, giving the curtain stain-resistant and wear-resistant properties while meeting decorative requirements.

[0063] The light-shielding layer 12 is composed of a high-density light-shielding base fabric 121, a nano-light-shielding coating 122, and a micro-airbag heat insulation layer 123, which together achieve efficient light-shielding and heat insulation functions.

[0064] High-density light-blocking base fabric 121: It is made of polyester filament (80D) and nylon fiber (70D) blended in a ratio of 6:4, woven on a water jet loom, with the yarn density controlled at 650 yarns / 10cm (350 yarns in the warp and 300 yarns in the weft). After weaving, it is set (180℃, 30 seconds) to ensure the flatness of the base fabric, providing a stable foundation support for the light-blocking layer. Its own tight structure also has a certain light-blocking capacity.

[0065] Nano-light-shielding coating 122: Titanium dioxide (particle size 30nm) and carbon black (particle size 20nm) are mixed in a 3:1 ratio, and water-based acrylic resin (solid content 40%) is added to make a coating slurry (solid content 25%). The slurry is then uniformly coated on the inner surface of the high-density light-shielding base fabric 121 using a doctor blade coater, with a coating thickness of 0.04mm. After drying at 100℃ for 3 minutes, a light-shielding coating is formed. The light-shielding effect is enhanced by utilizing the properties of nanomaterials, effectively blocking light penetration.

[0066] Micro-airbag insulation layer 123: Polyvinyl alcohol microspheres (50μm in diameter, 80% hollowness) are mixed with water-based adhesive (30% solid content) and coated onto the surface of nano-shielding coating 122 by spraying process. The coating thickness is 0.15mm. After drying at 80℃ for 2 minutes, an insulation layer containing still air is formed. The excellent heat insulation properties of still air are used to reduce the heat exchange between indoor and outdoor environments and improve the heat insulation performance.

[0067] Antibacterial layer 13: Bamboo fiber (30%) and polyester fiber (70%) are mixed and spun into yarn (32 count), woven into fabric, and then subjected to antibacterial treatment: The fabric is immersed in a 2% concentration chitosan quaternary ammonium salt antibacterial agent solution (liquor ratio 1:20), with a padding pressure of 0.3MPa and a padding rate of 80%, and then baked at 120℃ for 3 minutes to allow the antibacterial agent to cross-link and solidify with the fiber. With the help of the bamboo fiber itself and the antibacterial agent, it can inhibit bacterial growth for a long time and keep the curtains clean and hygienic.

[0068] Magnetic positioning block 2: It is fixedly connected to both sides of the curtain body 1, which allows the curtain to be magnetically attracted to the window frame to ensure the light blocking effect, and at the same time allows two adjacent curtains to close better to prevent light from leaking through gaps;

[0069] Upper bushing 3: Fixedly connected to the upper end of the curtain body 1, with a silicone strip 31 fixedly connected inside; the silicone strip 31 (rectangular cross-section, 2cm long, 0.5cm wide, and weighing 50g / m) is embedded in the upper bushing 3 pre-set at the top of the curtain body 1. The bushing is fixed by a locking edge process to ensure that the silicone strip 31 is flat and wrinkle-free, so that the top of the curtain can fit tightly against the upper edge of the window frame, enhancing the top sealing, reducing light leakage, and improving the stability of the installation;

[0070] Lower lining 4: It is fixedly connected to the lower end of the curtain body 1 and has a counterweight 41 inside; a long strip of cloth bag (2cm wide) is sewn at the bottom of the curtain body 1 to form the lower lining 4, which is filled with lead weights (total weight 120g / m). Zippers are set at both ends of the cloth bag, and the weight can be adjusted by adding or removing lead weights to ensure that the bottom of the curtain hangs naturally, keeps the whole flat, and avoids the bottom from sticking up and letting in light;

[0071] Sliding ring 5: Embedded in the curtain body 1, with an expansion hole 51 on the inner wall. A support rod 52 is slidably connected inside the expansion hole 51, and a ball bearing 53 is rotatably connected to one end of the support rod 52. A spring 54 is fixedly connected inside the expansion hole 51, and the other end of the spring 54 is fixedly connected to the support rod 52. During installation, the sliding ring 5 is fitted onto the curtain frame. The ball bearing 53 fits against the surface of the curtain frame to reduce friction, making the pulling smoother. Under the action of the spring 54, the ball bearing abuts against the curtain frame, making it difficult for the curtain to move randomly after being pulled, ensuring the positioning effect and stopping at the designated position.

[0072] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
