Description

Technical Field

[0001] The utility model relates to a curtain fabric, in particular to a flame-retardant, heat-insulating and sound-absorbing multifunctional curtain fabric. Background Art

[0002] The main function of curtains is to isolate the outside world and maintain the privacy of the room. At the same time, they are also an indispensable decoration for home decoration. Modern curtains require both light reduction and light blocking to meet people's needs for different light intensities, and to isolate indoor and outdoor noise to improve the living environment. At the same time, as people's safety awareness continues to improve, the safety requirements for curtain fabrics are also getting higher and higher, requiring curtain fabrics to be flame retardant, heat-insulating, sound-absorbing, etc., to improve the climate and environment of the room.

[0003] People have higher and higher requirements for fabrics, but when fabrics are used for curtains, they are not universal. Curtains are usually made of cotton, polyester or linen, but these fabrics have one thing in common, which is that they are flammable. Once a fire occurs, the flammability of the fabric will affect people's personal and property safety.

[0004] At present, there are still many single-function fabrics on the market. Although some of them also have flame retardant and sound insulation effects, they mainly use sound-absorbing cotton or sponge to achieve sound absorption and heat insulation effects, and flame-retardant polyester filaments to achieve flame retardant effects. In addition, heat insulation layer, UV protection layer and light-shielding layer increase the thickness of the curtains, and the appearance plasticity is low. The comprehensive flame retardant, antibacterial and sound insulation effects of the fabrics are poor, and the practicality is not strong. They cannot meet the living needs of the public. Moreover, for public places such as hotels and hospitals, the demand for a curtain that is safe, environmentally friendly, flame retardant and other multifunctional is particularly important.

[0005] Soft melamine foam material is a soft foam plastic with low density and high open porosity. It has excellent flame retardancy, sound absorption, thermal insulation, wide weather resistance, wear resistance, chemical resistance, and environmental friendliness. It is a safe, environmentally friendly, and energy-saving new material. Using soft melamine foam material in the interlayer of curtain fabrics can play a role in heat insulation, heat preservation, sound absorption, and flame retardancy. The composite use of soft melamine foam material and flame retardant fabric can overcome the shortcomings of existing curtains that are extremely easy to burn and have poor flame retardant and noise reduction effects, and has good application prospects. Utility Model Content

[0006] The purpose of the utility model is to provide a flame retardant, heat insulating and sound absorbing multifunctional curtain fabric in response to the above-mentioned problems, so as to solve the shortcomings of the existing technology such as single function and flammability of curtains, and not only can it play the role of beauty, dustproof and light shielding, but also has high flame retardancy and sound absorption and noise reduction, eliminating the fire hazard of curtains.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A flame retardant, heat insulating, sound absorbing, multifunctional curtain fabric, comprising a surface fabric layer, an intermediate functional layer, and a base fabric layer, wherein the surface fabric layer and the base fabric layer are both flame retardant textiles formed by interweaving warp yarns and weft yarns, an upper surface of the surface fabric layer is coated with an anti-ultraviolet coating, the intermediate functional layer is a noise reduction material layer having the functions of heat preservation, heat insulation, sound absorption, and flame retardancy, and the surface fabric layer, the intermediate functional layer, and the base fabric layer are connected to each other in pairs by a flame retardant adhesive.

[0009] Preferably, the surface fabric layer and the base fabric layer are any one of aramid flame-retardant fabric, ecological flame-retardant fabric, pure cotton flame-retardant fabric, CVC flame-retardant fabric, nylon-cotton flame-retardant fabric, and multifunctional flame-retardant fabric.

[0010] Preferably, the intermediate functional layer is a soft melamine foam material layer.

[0011] Preferably, the fabric structure of the intermediate functional layer is one of ordinary soft melamine foam material, hydrophobic soft melamine foam material and antibacterial soft melamine foam material.

[0012] Preferably, the intermediate functional layer is a hot-pressed soft melamine foam material that has been compressed at high temperature.

[0013] Preferably, the thickness of the intermediate functional layer is 0.5-50 mm.

[0014] Preferably, the intermediate functional layer is a three-dimensional network foam structure.

[0015] Preferably, the anti-ultraviolet coating is a nano titanium dioxide coating.

[0016] Preferably, the flame retardant adhesive is an environmentally friendly nano adhesive.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] 1. The soft melamine foam material is used in the interlayer of the curtain fabric. Its three-dimensional mesh structure system allows sound waves to easily and effectively enter the deep layer of the foam body and transform into the vibration of the mesh to be consumed and absorbed, thereby improving the sound absorption effect of the fabric, especially for medium and high frequency noise. It has outstanding absorption characteristics. At the same time, the fine three-dimensional mesh structure effectively prevents the convection heat transfer of the air, and the unique low thermal stability further improves the thermal insulation effect of the curtain fabric.

[0019] 2. Compared with commonly used sound-absorbing materials such as soft polyurethane foam and polyethylene foam, soft melamine foam has better flame retardancy and does not require any flame retardant. It can reduce its flammability in flames and slow down the burning speed. At the same time, it quickly forms a dense coke layer on the surface of the burning body and effectively prevents the burning from developing deeper. It will automatically extinguish after the open flame leaves, that is, it will extinguish as soon as it leaves the flame.

[0020] 3. The composite use of soft melamine foam material and flame retardant fabric has the advantages of heat preservation, heat insulation, sound absorption and noise reduction, flame retardancy, aging resistance, wear resistance, and environmental friendliness. It can be widely used in various complex environments, especially in public places with high requirements for flame retardancy, to win precious time for escape and disaster relief.
