[0012] Based on the above scheme and as a preferred embodiment of the above scheme: a porous sound-absorbing and flame-retardant bamboo fiber aerogel layer is provided between the reinforced flame-retardant mesh layer and the second spunlace flame-retardant nonwoven fabric layer.

[0013] The beneficial effects of this utility model are as follows: The three-proof flame-retardant spunlace composite nonwoven fabric involved in this utility model uses a three-proof flame-retardant coating that provides both three-proof effects and flame-retardant properties. Furthermore, the reinforced flame-retardant mesh layer improves the strength of the spunlace composite nonwoven fabric, making it less prone to tearing. Additionally, the flame-retardant and antibacterial polyester fibers used provide a certain degree of antibacterial effect. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] Combination Figure 1 This embodiment will be described in detail. The three-proof flame-retardant spunlace composite nonwoven fabric involved in this embodiment includes a first spunlace flame-retardant nonwoven fabric layer 1, a reinforcing flame-retardant mesh fabric layer 2, and a second spunlace flame-retardant nonwoven fabric layer 3, all composited together. Specifically, a flame-retardant adhesive is used for the composite.

[0020] A three-proof flame-retardant coating 4 is provided on the surface of the first spunlace flame-retardant nonwoven fabric layer 1 away from the reinforcing mesh fabric layer 2. The three-proof flame-retardant coating 4 is applied to the surface of the first spunlace flame-retardant nonwoven fabric layer 1 by a doctor blade coating method. In the flame-retardant foam finishing agent, the mass concentrations of the foaming agent and the foam stabilizer are 8 and 0.4 g / L, respectively, the mass concentration of the flame retardant is 100-500 g / L, and the mass concentration of the three-proof finishing agent is 10-50 g / L. The finishing liquid is foamed at 30℃ with a shear rate controlled at 3500 r / min for 2 min.

[0021] The second spunlace flame-retardant nonwoven fabric layer 3 includes a parallel web fiber layer 31 and a cross-web fiber layer 32; the parallel web fiber layer 31 uses flame-retardant and antibacterial polyester fiber, and the cross-web fiber layer 32 uses aramid fiber; the parallel web fiber layer 31 is located near the side where the flame-retardant mesh fabric layer 2 is added. The flame-retardant and antibacterial polyester fiber can provide a certain antibacterial effect. Furthermore, the aramid fiber has good flame-retardant properties.

[0022] Furthermore, the reinforced flame-retardant mesh layer 2 is woven from flame-retardant nylon filaments and has a square mesh with a side length of 3-5 cm. The reinforced flame-retardant mesh layer 2 increases the strength of the spunlace composite nonwoven fabric, making it less prone to tearing and deformation during use. The reinforced flame-retardant mesh layer 2 is woven from filaments, while in this embodiment, the nonwoven fabric is made from short fibers through carding and hydroentangling reinforcement. Nonwoven fabrics prepared from short fibers have low strength, while the mesh fabric woven from filaments can provide greater strength.

[0023] Furthermore, the fibers used in the first spunlace flame-retardant nonwoven fabric layer 1 are flame-retardant polyester fibers. A water-repellent agent is attached to the surface of the flame-retardant polyester fibers.

[0024] Furthermore, flame-retardant and antibacterial polyester fiber is made from semi-dull polyethylene terephthalate (PET) chips as raw material. During the spinning process, spectral heating flame-retardant and antibacterial composite functional masterbatch is added by melt blending, and drying and spinning are carried out in a reasonable manner.

[0026] Combination Figure 2 This embodiment will be described in detail below. The difference between the three-proof flame-retardant spunlace composite nonwoven fabric involved in this embodiment and that in Embodiment 1 is that a porous sound-absorbing and flame-retardant bamboo fiber aerogel layer 5 is provided between the reinforcing flame-retardant mesh layer 2 and the second spunlace flame-retardant nonwoven fabric layer 3. This porous structure provides sound insulation.

[0027] 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.
