Description
Technical Field
The utility model relates to a composite fabric, in particular to a flame-retardant three-proofing composite fabric.
Background
The composite fabric has soft hand feeling, thick touch feeling, effective sound absorption and noise reduction capability, improves the use touch feeling of the rigid carving plate such as plastic parts and sheet metal parts, brings comfort to users, and is generally applied to the interior decoration industry in the traffic field.
According to incomplete statistics, a passenger car needs at least 30 m2The composite fabric is commonly used in a plurality of positions such as a ceiling, a door panel, a seat, a floor and the like. Due to the large-area utilization of the composite fabric on the host machine, the test standard aiming at the combustion characteristic of the fabric for the vehicle is one of important factors for ensuring the use safety of the vehicle. At present, the combustion characteristic of the automobile fabric is only adopted by the automobile fabric in the national mandatory standard GB8410-2006, the combustion speed is only required in the horizontal direction, and the automobile composite fabric is not suitable for all real combustion characteristics of the automobile fabric. The technical standard JT/T1095 which is required by the Ministry of industry and correspondence to organize and perfect and supplement is formally implemented in No. 4/1 of 2017, and makes requirements on specific indexes such as oxygen index, vertical combustion speed, smoke density and the like. Meanwhile, in the use process of a vehicle, as time is accumulated and people flow, the interior composite material has the problems of dust accumulation, difficult stain treatment, bacteria breeding and the like, and a user puts forward the surface performance of the composite fabric which is easy to treat, easy to remove and free of stainAnd (4) demand.
Disclosure of Invention
The utility model aims to provide a flame-retardant three-proofing composite fabric aiming at the problems that the flame retardant property and the three-proofing property are difficult to be compatible in the prior art, the flame retardant property requirement of JT/T1095 on a ceiling fabric is satisfied, and the market requirement and the standard requirement are met.
In order to realize the purpose, the utility model is realized by the following technical scheme: the flame-retardant three-proofing composite fabric comprises a three-proofing surface layer, wherein a composite hot-melt film layer is bonded below the three-proofing surface layer, and a flame-retardant bottom lining layer is bonded below the composite hot-melt film layer.
Further, the three-proofing surface layer is preferably a fabric which is subjected to surface modification finishing by a nano three-proofing finishing agent or a fluorine-containing three-proofing finishing agent and is formed by warp knitting cloth, weft knitting cloth or woven fabric.
Further, the composite hot melt film layer is preferably a low-melting-point EVA film.
Further, the flame-retardant bottom lining layer is preferably flame-retardant non-woven fabric, flame-retardant single-sided velvet or flame-retardant polyurethane sponge made of flame-retardant fibers.
Further, the three-proofing surface layer, the composite hot-melt film layer and the flame-retardant bottom lining layer are compounded in a flame melting bonding processing mode.
The utility model has the beneficial effects that: the flame-retardant three-proofing composite fabric has good waterproofness, antifouling property and flame retardance. Tests show that the composite fabric has the surface properties of more than 80 grades of waterproof performance, more than 4 grades of oil-proof performance, easy decontamination of liquid stains and solid stain resistance, and simultaneously, the flame retardant property of the composite fabric meets the national standard JT/T1095.

Detailed Description
The utility model discloses a flame-retardant three-proofing composite fabric, which comprises a three-proofing surface layer 1, wherein a composite hot-melt film layer 2 is bonded below the three-proofing surface layer 1, and a flame-retardant bottom lining layer 3 is bonded below the composite hot-melt film layer 2, as shown in figure 1. The three-proofing surface layer 1, the composite hot-melt film layer 2 and the flame-retardant bottom lining layer 3 are compounded through a flame melting bonding processing mode. The three-proofing surface layer 1 is preferably a fabric which is obtained by surface modification finishing of warp-knitted cloth, weft-knitted cloth or woven fabric by a nano three-proofing finishing agent or a fluorine-containing three-proofing finishing agent. The composite hot melt film layer 2 is preferably a low-melting-point EVA film. The flame-retardant bottom lining layer 3 is preferably made of flame-retardant fibers, flame-retardant single-sided velvet or flame-retardant polyurethane sponge.
Example 1
200g/m flame-retardant three-proofing composite fabric2The liquid carrying amount of the warp-knitted fabric is 70-80% after the nano three-proofing finishing agent is added and padding is carried out during shaping, and the warp-knitted fabric is dried for later use and is used as a three-proofing surface layer 1 of the flame-retardant three-proofing composite fabric; 250g/m woven by using flame-retardant polyester filament2The single-sided velvet is used as the flame-retardant bottom lining layer 3, and the flame-retardant three-proofing composite fabric is prepared after the low-melting-point EVA film composite processing.
Through tests, the waterproof performance of the composite fabric prepared by the embodiment can meet the GB/T4745 spray test rating of more than 80 minutes; the oil-proof performance can meet the oil-proof performance rating of more than 4 grade of the standard test of hydrocarbon resistance of GB/T19977-; the soil release performance can meet the surface performance of liquid stains with soil release and solid stain resistance without stain of the standard GB/T30159.1-2013, the stain rating of the liquid stains such as soy sauce, peanut oil and the like is more than or equal to grade 5, and the stain rating of the solid stains is more than or equal to grade 3-4. Meanwhile, the flame retardant property of the composite fabric meets the requirement of standard JT/T1095. The test data are shown in tables 1 and 2 below.
