Description

Technical Field

[0001] This utility model relates to a curtain fabric, specifically a flame-retardant curtain fabric. Background Technology

[0002] Curtains, as common decorative and functional textiles in homes and public buildings, serve multiple purposes, including light blocking, sound insulation, and environmental beautification, and are widely used in various places such as homes, hotels, office buildings, shopping malls, and hospitals. However, traditional curtain fabrics are mostly made of conventional fibers such as cotton, linen, polyester, and synthetic fibers. These materials are usually flammable, have a low limiting oxygen index, and are prone to rapid combustion when exposed to open flames or high temperatures. Furthermore, the combustion process may produce a large amount of toxic fumes and molten drippings.

[0003] In fires, curtains often become a significant conduit for the spread of fire. When a fire breaks out, flames or high-temperature radiation can easily ignite curtains. Burning curtains not only accelerate the spread of fire to other areas, expanding the fire's scope, but the toxic fumes they produce also hinder evacuation and rescue efforts, increasing the risk of casualties. Therefore, it is necessary to provide a flame-retardant curtain fabric. Utility Model Content

[0004] The purpose of this invention is to provide a flame-retardant curtain fabric that has flame-retardant properties, reduces smoke emissions and toxic gas concentrations during a fire, and provides a safer escape environment for trapped personnel.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a flame-retardant curtain fabric, comprising: a base fabric layer, a first flame-retardant layer, and a second flame-retardant layer, wherein the first flame-retardant layer and the second flame-retardant layer are respectively disposed on both sides of the base fabric layer, and the base fabric layer, the first flame-retardant layer, and the second flame-retardant layer are connected by quilting; the first flame-retardant layer is woven from a first flame-retardant yarn; the second flame-retardant layer is woven from a second flame-retardant yarn; the base fabric layer is woven from warp yarns and weft yarns, wherein the warp yarns are polyester yarns, and the weft yarns are antibacterial and anti-mite yarns.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the first flame-retardant yarn is a blended yarn of methylene fiber and seaweed fiber.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the second flame-retardant yarn is a flame-retardant viscose yarn.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the polyester yarn is flame-retardant polyester fiber yarn.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial and anti-mite yarn is copper-modified antibacterial and anti-mite polyamide 6 fiber filament.

[0010] The beneficial effects of this utility model are as follows: Based on the flame-retardant curtain fabric of this utility model, a first and a second flame-retardant layer are respectively set on both sides of the base fabric layer to form flame-retardant protection. The limiting oxygen index of both the first and second flame-retardant layers exceeds 28%, which has good flame-retardant performance. Both can reduce the amount of smoke emission and the concentration of toxic gases during a fire, which is conducive to providing a safer escape environment for trapped people. The base fabric layer provides the main strength of the curtain fabric on the one hand, and also has antibacterial and anti-mite functions on the other hand. Attached Figure Description

[0011] Figure 1 This is a structural schematic diagram of the flame-retardant curtain fabric involved in this utility model; In the diagram: 1-base fabric layer, 2-first flame retardant layer, 3-second flame retardant layer. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] Example 1 Combination Figure 1 This embodiment provides a detailed description of a flame-retardant curtain fabric, comprising: a base fabric layer 1, a first flame-retardant layer 2, and a second flame-retardant layer 3. The first flame-retardant layer 2 and the second flame-retardant layer 3 are respectively disposed on both sides of the base fabric layer 1, and the base fabric layer 1, the first flame-retardant layer 2, and the second flame-retardant layer 3 are connected by quilting. The first flame-retardant layer 2 is woven from a first flame-retardant yarn; the second flame-retardant layer 3 is woven from a second flame-retardant yarn; the base fabric layer 1 is woven from warp yarns and weft yarns, wherein the warp yarns are polyester yarns and the weft yarns are antibacterial and anti-mite yarns.

[0014] Specifically, the yarns used in the quilting of the base fabric layer 1, the first flame-retardant layer 2, and the second flame-retardant layer 3 are flame-retardant yarns. In this embodiment, the flame-retardant yarns are polyimide fiber yarns. Polyimide fibers are high-performance aromatic heterocyclic polymers with a limiting oxygen index as high as 38%. They do not drip when carbonized with a high-temperature open flame, are self-extinguishing when removed from the flame, and are non-toxic. They also have good mechanical properties and dimensional stability.

[0015] Furthermore, the first flame-retardant yarn is a blend of methylene fiber and seaweed fiber. Specifically, the blending ratio of the methylene fiber / seaweed fiber blended yarn is 70 / 30. Methylene fiber is a dry-spun polyimide fiber, inherently flame-retardant, with a limiting oxygen index of 38%, and does not melt or drip when carbonized at high temperatures, producing extremely low and non-toxic combustion smoke. Seaweed fiber is a bio-based self-flame-retardant fiber with a limiting oxygen index as high as 45%. Seaweed fiber is self-extinguishing upon removal from the flame, non-toxic and smokeless, does not produce melting droplets, and does not cause secondary damage.

[0016] Furthermore, the second flame-retardant yarn is a flame-retardant viscose yarn. The flame-retardant viscose fiber has a length of 38mm and a linear density of 1.67dtex. Flame-retardant viscose fiber has excellent moisture absorption, breathability, and dyeing properties, as well as low smoke, non-toxicity, non-melting and dripping, odorless, fireproof and heat-resistant characteristics. Its limiting oxygen index is not less than 28%, and its waste has the property of natural degradation. It belongs to green and environmentally friendly fiber and is widely used in various textile fields.

[0017] Furthermore, the antibacterial and anti-mite yarn is a copper-modified antibacterial and anti-mite polyamide 6 fiber filament. The copper-modified antibacterial and anti-mite polyamide 6 fiber filament is produced by coating nano-spherical copper antibacterial agents with oleic acid, then blending and extruding with a polyamide 6 matrix to obtain antibacterial and anti-mite PA6 chips, which are then melt-spun. After 50 washes, the copper-modified antibacterial and anti-mite polyamide 6 fiber exhibits an antibacterial rate of over 99% against Escherichia coli, Candida albicans, and Staphylococcus aureus. Its fabric achieves the highest level of mildew resistance (Level 0) and a mite repellency rate of up to 89%, demonstrating strong and durable antibacterial, mildew-proof, and anti-mite properties.

[0018] Example 2 Based on Example 1, the polyester yarn is a flame-retardant polyester fiber yarn. Flame-retardant polyester fiber has permanent flame retardancy, contains no halogens, and only carbon, hydrogen, oxygen, and a small amount of phosphorus. Compared with traditional fibers containing halogenated flame retardants, flame-retardant polyester fiber does not produce asphyxiating toxic gases during combustion, has a limiting oxygen index of 30%, and features low smoke emission, good flame retardant effect, good thermal stability, and non-toxicity. It also possesses the advantages of polyester fiber, such as good wrinkle resistance and shape retention.

[0019] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
