Abstract
Description
Technical Field
[0001] This utility model relates to the field of blackout fabrics, specifically a washable and high-temperature resistant blackout fabric. Background Technology
[0002] Blackout fabric is a type of fabric used to block light. It is usually made of materials such as polyester fiber, cotton, and linen, and achieves its light-blocking effect through special weaving or coating processes. Blackout fabric has a relatively tight fiber structure and a special weaving method, which can effectively block light from passing through directly. Some blackout fabrics also have special coatings or films, such as silver coatings, which further enhance the light-blocking effect by reflecting light. Some blackout fabric materials themselves have the property of absorbing light of specific wavelengths, converting light into other forms of energy, thereby reducing the light transmitted into the room.
[0003] In summer and other times when the temperature is high, the air cannot pass through the blackout cloth well, resulting in poor indoor air circulation, which makes people feel more stuffy and reduces indoor comfort; while the blackout cloth can block light, it cannot also ensure breathability and heat dissipation. Utility Model Content
[0004] The purpose of this invention is to provide a washable, high-temperature resistant blackout fabric to address the deficiencies mentioned in the background section.
[0005] To achieve the above objectives, a washable and high-temperature resistant light-blocking fabric is provided, comprising a light-blocking surface fabric, a refraction platform fixedly disposed on the surface of the light-blocking surface fabric, a plurality of upper ventilation holes evenly distributed on the light-blocking surface fabric, a light-blocking base fabric covering the bottom of the light-blocking surface fabric, a blind fabric fixedly disposed on the bottom of the light-blocking base fabric, and a plurality of lower ventilation holes evenly distributed on the light-blocking base fabric.
[0006] Preferably, the light-shielding fabric, the light-shielding base fabric, and the blind fabric are arranged in layers from top to bottom, and the thickness of the blind fabric is equal to half the thickness of the light-shielding base fabric.
[0007] Preferably, the thickness of the light-blocking fabric and the light-blocking base fabric is the same, both being 1.5 mm, and the thickness of the blind fabric is 0.75 mm; the areas of the light-blocking fabric, the light-blocking base fabric, and the blind fabric are the same.
[0008] Preferably, the upper vent holes on the light-shielding fabric and the lower vent holes on the light-shielding base fabric are both circular; the distance between two adjacent sets of upper and lower vent holes is consistent.
[0009] Preferably, the bottom of the light-blocking fabric is evenly provided with multiple sets of connecting pieces, the connecting pieces are circular and the thickness of the connecting pieces is 1.3mm.
[0010] Preferably, a gas channel is formed between the light-shielding base fabric and the light-shielding surface fabric, and the gas channel, the upper vent, and the lower vent are combined to form the heat dissipation and ventilation mechanism of the light-shielding fabric.

[0013] Preferably, the bottom of the connecting piece is provided with a light-shielding base fabric, and the light-shielding base fabric and the light-shielding surface fabric are connected by multiple sets of connecting pieces.
[0014] Preferably, light reflecting surfaces are provided on both sides and the top of the refraction stage, the distance between two adjacent sets of refraction stages is the same, and the height of the refraction stage is 1.2mm.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model uses a combination of numerous upper vents on the blackout fabric, lower vents on the blackout base fabric, and gas channels to form a heat dissipation and ventilation mechanism for the blackout fabric. Airflow above the blackout fabric can enter the interior of the gas channels through the upper vents and exit into the lower part of the blackout fabric through the lower vents, and vice versa. The upper and lower vents form a through path through the gas channels, which promotes the natural flow of external airflow. When hot air rises, it forms a "chimney effect," which quickly carries away heat and prevents heat from accumulating between the fabrics. It is especially suitable for high-temperature environments or enclosed spaces; it can dissipate heat and allow ventilation while providing blackout.
[0017] 2. This utility model utilizes the active heat dissipation of airflow within the gas channel to reduce the internal temperature of the fabric, thereby reducing reliance on high-density insulation materials, thus lightening the overall weight and facilitating installation; it also reduces indoor air conditioning load, indirectly saving energy; the gas channel can absorb some sound waves, which, combined with the sound insulation properties of the blackout fabric, may improve the overall sound insulation effect; through the ingenious double-layer structure and gas channel design, it solves the problem of stuffiness in blackout fabrics while retaining the core function of blackout, combining functionality and practicality.

[0024] Please see Figure 1-5 This utility model provides a washable and high-temperature resistant light-blocking cloth, including a light-blocking surface cloth 1, a refraction table 11 fixedly disposed on the surface of the light-blocking surface cloth 1, a plurality of upper ventilation holes 12 evenly disposed on the light-blocking surface cloth 1, a light-blocking base cloth 4 covering the bottom of the light-blocking surface cloth 1, a blind cloth 5 fixedly disposed on the bottom of the light-blocking base cloth 4, and a plurality of lower ventilation holes 41 evenly disposed on the light-blocking base cloth 4.
[0025] Working Principle: This light-blocking cloth employs a double-layer design, consisting of a light-blocking surface cloth 1 and a light-blocking base cloth 4. Multiple connecting pieces 2 separate the surface cloth 1 and the base cloth 4, forming an air channel 3. The numerous upper vents 12 on the surface cloth 1, the lower vents 41 on the base cloth 4, and the air channel 3 together constitute the light-blocking cloth's heat dissipation and ventilation mechanism. Airflow above the light-blocking cloth can enter the interior of the air channel 3 through the upper vents 12 and exit into the light-blocking cloth through the lower vents 41. Conversely, at the bottom, the upper vent 12 and lower vent 41 form a continuous path through the gas channel 3, promoting natural airflow. When hot air rises, it creates a "chimney effect," quickly carrying away heat and preventing heat buildup between the fabric layers. This is especially suitable for high-temperature environments or enclosed spaces, such as sunrooms and car sunshades. Traditional blackout fabrics rely on material thickness or coatings to block light, easily leading to stuffiness. This design, through a double-layer isolation structure, maintains the density of the blackout fabric to block light while simultaneously allowing light to pass through through a dispersed permeability... The vents and air channels 3 facilitate air exchange, resolving the conflict between shading and ventilation. The supporting function of the connecting piece 2 not only forms the air channel 3, preventing the two layers of fabric from sticking together and ensuring smooth airflow, but also disperses stress, reducing the risk of deformation during long-term use and improving wind resistance. Near the shading fabric, airflow can flow from top to bottom or in the opposite direction, adapting to day and night temperature changes according to the direction of temperature difference. The design of the upper vent 12 and lower vent 41 can also expel moisture, prevent condensation, reduce the risk of mold growth, and is suitable for humid areas. When the airflow flows inside the air channel 3, it actively dissipates heat, reducing the internal temperature of the fabric, thus reducing reliance on high-density insulation materials, thereby reducing the overall weight and facilitating installation. It also reduces the indoor air conditioning load, indirectly saving energy. The air channel 3 can absorb some sound waves, which, combined with the sound insulation properties of the shading fabric, may improve the overall sound insulation effect. Through the ingenious double-layer structure and the design of the air channel 3, the core function of shading is retained while solving the problem of stuffiness in shading fabric, combining functionality and practicality.
[0026] The blind fabric 5 is preferably made of dark-colored fabric, which can absorb light. At the same time, multiple sets of refraction tables 11 are evenly arranged on the surface of the light-blocking fabric 1. When light shines on the refraction tables 11, it can produce diffuse reflection, thereby reducing the transmission of light and improving the light-blocking effect.
[0027] The multiple sets of upper vent holes 12 and multiple sets of lower vent holes 41 are staggered, so that no matter which angle the light enters the interior of the upper vent holes 12, it will not pass through the lower vent holes 41, so that the blackout cloth has the advantages of both blackout and heat dissipation and breathability.
[0028] In a preferred embodiment, the light-blocking fabric 1, the light-blocking base fabric 4, and the blind fabric 5 are arranged in layers from top to bottom, and the thickness of the blind fabric 5 is equal to half the thickness of the light-blocking base fabric 4.

The gas channel 3, the upper vent 12, and the lower vent 41 are combined together to form the heat dissipation and ventilation mechanism of the light-shielding fabric.
[0033] In a preferred embodiment, multiple sets of refraction tables 11 are evenly arranged on the surface of the light-shielding cloth 1, and the cross-section of the refraction tables 11 is an isosceles trapezoid.
[0034] In a preferred embodiment, the upper vent 12 and the lower vent 41 have the same diameter, and the multiple sets of upper vent 12 and the multiple sets of lower vent 41 are staggered.

[0036] As a preferred embodiment, light reflecting surfaces are provided on both sides and the top of the refraction stage 11, the distance between two adjacent sets of refraction stages 11 is the same, and the height of the refraction stage 11 is 1.2mm.
