Description

Technical Field

[0001] The utility model belongs to the field of non-woven fabrics, and in particular relates to a flame-retardant non-woven fabric. Background Art

[0002] Nonwoven fabrics are also called nonwovens, nonwoven fabrics, and non-woven fabrics. They are made of oriented or randomly arranged fibers through friction, cohesion, bonding, or a combination of these methods. The connotation is "non-woven". Nonwoven fabrics exist in the form of fibers, while woven fabrics exist in the form of yarns. This is also a major feature that distinguishes nonwoven fabrics from other fabrics. You cannot pull out individual threads from nonwoven fabrics.

[0003] Existing non-woven fabrics are all flammable. Therefore, in order to improve the flame retardancy of some non-woven fabrics, flame retardants or one to several flame retardant layers are usually added to the fabric. However, in order to improve the flame retardancy, some flame retardant non-woven fabrics choose to sacrifice their own breathability, which affects their scope of application. Utility Model Content

[0004] The utility model provides a flame retardant nonwoven fabric to solve the above technical problems.

[0005] The solution adopted by the utility model to achieve its technical effect is:

[0006] A flame-retardant nonwoven fabric comprises a PET fiber skeleton base layer; the PET fiber skeleton base layer is provided with air holes; breathable flame-retardant layers are provided on both sides of the PET fiber skeleton base layer; an isolation air-permeable layer is provided on the surface of the air-permeable flame-retardant layer; and a melt-blown nonwoven fabric dust-holding layer is provided on the surface of the isolation air-permeable layer.

[0007] Preferably, the breathable flame retardant layer is a flame retardant viscose fiber layer.

[0008] Preferably, the isolation and breathable layer is a blended layer of polyester fiber and flame-retardant viscose fiber.

[0009] Preferably, the meltblown nonwoven dust holding layer is a PP meltblown nonwoven dust holding layer.

[0010] The beneficial effects of the utility model are as follows: the base layer adopts PET skeleton fiber, which is convenient for arranging air holes in the structure while maintaining the overall supporting strength of the non-woven fabric, and then a breathable flame retardant layer is arranged on both sides of the base layer, such as a flame retardant viscose fiber layer. The utility model can have higher air permeability while ensuring flame retardant performance, and is applicable to a relatively wider range of application fields. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. It should be noted that when an element is referred to as "fixed on" or "set on" another element, it can be directly on the other element or there may be a centering element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be a centering element at the same time. When an element is referred to as being "fixedly connected to" another element, it can be a common fixed connection method such as welding, bolting or gluing.

[0014] Please refer to Figure 1 In a preferred embodiment of the utility model, a flame-retardant non-woven fabric is disclosed, comprising a PET fiber skeleton base layer 1; air holes 2 are arranged on the PET fiber skeleton base layer 1; breathable flame-retardant layers 3 are arranged on both sides of the PET fiber skeleton base layer 1; an isolation breathable layer 4 is arranged on the surface of the breathable flame-retardant layer 3; and a melt-blown non-woven dust-holding layer 5 is arranged on the surface of the isolation breathable layer 4.

[0015] Specifically, the breathable flame-retardant layer 3 is a flame-retardant viscose fiber layer.

[0016] Specifically, the isolation breathable layer 4 is a blended layer of polyester fiber and flame retardant viscose fiber.

[0017] Specifically, the meltblown nonwoven dust holding layer 5 is a PP meltblown nonwoven dust holding layer.

[0018] It can be seen from the above description that the utility model can ensure flame retardant performance while having high air permeability, and is applicable to a relatively wider range of application fields.

[0019] The preferred embodiments of the present invention are described in detail above in conjunction with the drawings in the specification. It should be noted that the protection scope of the present invention includes but is not limited to the above embodiments. The specific structures disclosed in the drawings in the specification are only preferred embodiments of the present invention. Technical personnel in the field can also develop other embodiments on this basis. Any simple deformation or equivalent substitution that does not deviate from the innovative concept of the present invention is covered by the present invention and belongs to the protection scope of the present invention.
