Drawings
FIG. 1 is a schematic view of a low odor flame retardant back coated nonwoven fabric according to an embodiment;
Fig. 2 is a schematic structural diagram of a low-odor flame-retardant coated nonwoven fabric for a chair back according to a second embodiment.
The labels in the figures are illustrated below: 1-a first fiber aggregate; 2-polyacrylonitrile-based pre-oxidized fabric; 3-a second fiber aggregate; 4-an aqueous flame retardant coating; a 5-flame retardant adhesive layer; 6-a flame retardant viscose fiber layer; 7-flame retardant microcapsules.
Detailed Description
The utility model will be further described with reference to the drawings and specific examples.
Example 1
This embodiment will be described in detail with reference to fig. 1. The low-odor flame-retardant back coating non-woven fabric comprises a first fiber aggregate 1, polyacrylonitrile-based pre-oxidized fabric 2 and a second fiber aggregate 3 which are compounded by needling; the first fiber aggregate 1 is a flame-retardant polyester fiber net; the surface of the first fiber aggregate 1, which is far away from the polyacrylonitrile-based pre-oxidized cloth 2, is coated with an aqueous flame-retardant coating layer 4.
Furthermore, the polyacrylonitrile-based pre-oxidized fiber 2 is formed by interweaving polyacrylonitrile pre-oxidized fibers serving as warp and weft yarns. The polyacrylonitrile pre-oxidized fiber is oxidized from polyacrylonitrile, does not burn, melt, soften or melt drop, has the LOI index of more than 40%, is far used for other organic fibers in the aspect of flame retardant property, and has good thermal stability and chemical resistance. In addition, the polyacrylonitrile-based pre-oxidized fabric 2 is woven fabric in the embodiment, so that the whole low-odor flame-retardant back coating non-woven fabric has good dimensional stability and good breaking strength.
Further, the second fiber aggregate 3 is an antibacterial polyester fiber web. The antibacterial polyester fiber net can provide antibacterial performance for the low-odor flame-retardant back coating non-woven fabric.
Further, the water-based flame-retardant coating 4 is reactive boron-phenolic modified water-based polyurethane. The used waterborne polyurethane flame-retardant coating can effectively reduce the odor of the low-odor flame-retardant chair back coating non-woven fabric, thereby reducing the influence on a driver as much as possible.
Example two
This embodiment will be described in detail with reference to fig. 2. The difference between the low-odor flame-retardant back coating nonwoven fabric and the first embodiment is that: the side of the second fiber aggregate 3 far away from the polyacrylonitrile-based pre-oxidized cloth 2 is compounded with a flame-retardant viscose fiber layer 6 through a flame-retardant adhesive layer 5.
Further, the flame retardant microcapsules 7 are distributed in the flame retardant mixture layer 5. The flame retardant microcapsule 7 is made of natural or synthetic polymer material, and the flame retardant dispersed into particles is wrapped inside the microcapsule to form an inert protective film. When combustion occurs, the capsule is destroyed, and the flame retardant is released, so that the flame retardant effect is achieved. The microcapsule technology has the advantages that substances in the capsule can be isolated from the outside, and the substances are protected from the influence of external factors, so that the substances are fully utilized; on the other hand, the embedding substance can be released through the capsule wall by changing the structure of the capsule wall under proper conditions, so that the release performance of the core material is improved, and the purpose of controlling release is achieved.
The foregoing describes in detail preferred embodiments of the present utility model. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the utility model by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
