Abstract
Description
Technical Field
[0001] The present application relates to the technical field of flame-retardant fabrics, and in particular to a double flame-retardant fabric. Background Art
[0002] In the production standard requirements of mattress fabrics, they need to meet certain flame retardant standards, such as mattress fabrics exported to the United States; traditional flame retardant fabrics generally include a two-layer structure, namely the surface layer to ensure the feel of the fabric and the flame retardant base layer to ensure its flame retardant effect.
[0003] In actual production, hot melt adhesive, water glue and other colloids are usually used to bond the surface layer and the flame retardant base layer. In order to ensure a cool feeling, the surface layer is generally made of ice silk material; however, this fabric generally has the following problems:
[0004] Ice silk fabric is flammable. Once ignited, it will quickly penetrate the glue and directly into the flame retardant base layer. Some manufacturers adopt the method of increasing and thickening the glue layer to meet the corresponding flame retardant requirements. However, it will affect the overall feel of the fabric and increase the production cost of the fabric. Utility Model Content
[0005] The purpose of this application is to provide a double flame retardant fabric to solve at least one of the above technical problems.
[0006] In order to solve the above technical problems, the present application provides a double flame retardant fabric, comprising an air layer, a first flame retardant layer and a second flame retardant layer;
[0007] The first flame retardant layer is disposed on the bottom surface of the air layer and forms a film-like structure on the bottom surface of the air layer;
[0008] The second flame retardant layer is disposed on the bottom surface of the first flame retardant layer, and the first flame retardant layer is used to connect the air layer and the second flame retardant layer;
[0009] In the above-mentioned implementation process, the fabric provided by the present application adopts a double flame-retardant design, wherein the first air layer can be understood as the outermost layer of the fabric, which is used to ensure the comfort of the fabric; when used as a mattress cloth, if the air layer is burned through, the first flame-retardant layer located thereunder forms a membrane-like structure, which will prevent the fire from spreading further. If the fire is too large and passes through the first flame-retardant layer, the second flame-retardant layer will further exert a flame-retardant effect. It can be understood that after passing through the first flame-retardant layer, most of the combustion can be controlled. Therefore, when entering the second flame-retardant layer, the loss of the second flame-retardant layer is very small, so the structure below the second flame-retardant layer can be better protected; the first flame-retardant layer not only plays a flame-retardant function, but also plays a role in fixing the air layer and the second flame-retardant layer.
[0010] Preferably, the first flame retardant layer comprises PUR flame retardant glue;
[0011] In the above implementation process, this scheme uses high-purity environmentally friendly PUR flame-retardant glue as the first flame-retardant layer. First, it can play a good adhesion role on the air layer and the second flame-retardant layer, so that the overall structural bonding effect is better; second, compared with traditional hot melt adhesives and water adhesives, it has better flame retardant effect and uses less; third, its actual usage can be less, so it can better control the overall thickness of the fabric and improve its texture when used; fourth, using PUR flame-retardant glue as the first flame-retardant layer is also relatively environmentally friendly in use, and is colorless and odorless.
[0012] Preferably, the thickness of the first flame retardant layer is 0.5-2 mm;
[0013] In the above implementation process, if the thickness of the first flame retardant layer is too low, the membrane structure cannot be effectively formed, which will eventually affect the flame retardant effect of the fabric, and may not meet the corresponding flame retardant standards, thus affecting the normal listing of the product; if the thickness is too high, the fabric will become hard, which will not only increase the cost, but also affect the user experience.
[0014] Preferably, the air layer is covered with 10-20 g of the first flame retardant layer per square meter.
[0015] Preferably, the second flame retardant layer comprises one of rib flame retardant cloth, aramid flame retardant cloth, glass fiber coated yarn, pre-oxidized yarn, core-spun yarn, glass fiber cloth, carbon fiber flame retardant cloth, flat flame retardant cotton, and flame retardant needle-punched cotton.
[0016] Preferably, the thickness of the second flame retardant layer is 3-15 mm;
[0017] Preferably, the mass per square meter of the second flame retardant layer is 130-330g;
[0018] In the above implementation process, if the thickness of the second flame retardant layer is too thin, or its unit weight is too low, it will affect the flame retardant properties of the fabric, and ultimately may not meet the corresponding flame retardant standards, affecting the normal listing of the product. If the thickness of the fabric is too thick or the unit weight is too large, it will affect the product's texture and increase the cost.
[0019] Preferably, the air layer includes one of polyester fiber, high molecular ice silk, medium molecular ice silk, pure cotton, rayon, linen, and brass fiber.
[0020] Preferably, the thickness of the air layer is 3-30 mm;
[0021] Preferably, the mass of the air layer per square meter is 160-520g;
[0022] In the above implementation process, if the thickness of the air layer is too thin, or its unit weight is too low, it may affect the texture of use; if the thickness of the fabric is too thick or the unit weight is too large, it will affect the texture of the product and increase the cost.
[0023] Compared with the prior art, the beneficial effects of the present application are: the fabric provided by the present application adopts a double flame-retardant design, wherein the first air layer can be understood as the outermost layer of the fabric, which is used to ensure the comfort of the fabric; when used as a mattress cloth, if the air layer is burned through, the first flame-retardant layer located thereunder forms a membrane-like structure, which will prevent the fire from spreading further, and if the fire is too large and passes through the first flame-retardant layer, the second flame-retardant layer will further exert a flame-retardant effect. It can be understood that after passing through the first flame-retardant layer, most of the combustion can be controlled, so when entering the second flame-retardant layer, the loss of the second flame-retardant layer is very small, so the structure below the second flame-retardant layer can be better protected; the first flame-retardant layer not only plays a flame-retardant function, but also plays a role in fixing the air layer and the second flame-retardant layer.

[0034] Example
[0035] In the production standard requirements of mattress fabrics, they need to meet certain flame retardant standards, such as mattress fabrics exported to the United States; traditional flame retardant fabrics generally include a two-layer structure, namely a surface layer to ensure the feel of the fabric and a flame retardant base layer to ensure its flame retardant effect. In actual production, hot melt adhesives, water glues and other colloids are usually used to bond the surface layer and the flame retardant base layer. In order to ensure a cool feeling, the surface layer generally uses polymer ice silk materials; however, this fabric generally has the following problems: ice silk fabric is flammable, and when it is ignited, it will quickly pass through the glue and directly penetrate into the flame retardant base layer. Some manufacturers use the method of increasing and thickening the glue layer to meet the corresponding flame retardant requirements, but this will affect the overall comfortable feel of the fabric and increase the production cost of the fabric; in order to solve the above technical problems, this embodiment provides the following technical solutions:
[0036] For details, see Figure 1 , this embodiment provides a double flame retardant fabric, including an air layer 10, a first flame retardant layer 20 and a second flame retardant layer 30;
[0037] Specifically, the first flame retardant layer 20 is disposed on the bottom surface of the air layer 10 and forms a film-like structure on the bottom surface of the air layer 10;
[0038] Specifically, the second flame retardant layer 30 is disposed on the bottom surface of the first flame retardant layer 20 , and the first flame retardant layer 20 is used to connect the air layer 10 and the second flame retardant layer 30 .
[0039] In the above scheme, the fabric provided in the present application adopts a double flame-retardant design, wherein the first air layer 10 can be understood as the outermost layer of the fabric, which is used to ensure the comfort of the fabric; when used as a mattress cloth, if the air layer 10 is burned through, the first flame-retardant layer 20 located thereunder forms a membrane-like structure, which will prevent the fire from spreading further. If the fire is too large and passes through the first flame-retardant layer 20, the second flame-retardant layer 30 will further exert its flame-retardant effect. It can be understood that after passing through the first flame-retardant layer 20, most of the combustion can be controlled. Therefore, when entering the second flame-retardant layer 30, the loss of the second flame-retardant layer 30 is very small, so the structure below the second flame-retardant layer 30 can be better protected; the first flame-retardant layer 20 not only plays a flame-retardant function, but also plays a role in fixing the air layer 10 and the second flame-retardant layer 30.
[0040] Specifically, in one embodiment, the first flame retardant layer 20 includes PUR flame retardant glue;
[0041] In the above scheme, this scheme uses PUR flame retardant glue as the first flame retardant layer 20. First, it can have a good adhesion effect on the air layer 10 and the second flame retardant layer 30, so that the overall structural bonding effect is better; second, compared with traditional yellow glue and water glue, its flame retardant effect is better; third, its actual usage can be less, so it can better control the overall thickness of the fabric and improve its texture when used; fourth, using PUR flame retardant glue as the first flame retardant layer 20 is also relatively environmentally friendly in use.
[0042] Specifically, the thickness of the first flame retardant layer 20 is 0.5-2 mm;
[0043] In the above scheme, if the thickness of the first flame retardant layer 20 is too low, the membrane structure cannot be effectively formed, which will eventually affect the flame retardant effect of the fabric, and may not meet the corresponding flame retardant standards, thereby affecting the normal listing of the product; if the thickness is too high, the fabric will become hard, which will not only increase the cost, but also affect the user experience.
[0044] Specifically, the air layer 10 is covered with 10-20 g of the first flame retardant layer 20 per square meter.
[0045] Specifically, the second flame retardant layer 30 includes one of rib flame retardant cloth, aramid flame retardant cloth, glass fiber coated yarn, pre-oxidized yarn, core-spun yarn, glass fiber cloth, carbon fiber flame retardant cloth, flat flame retardant cotton, and flame retardant needle cotton.
[0046] Further, the thickness of the second flame retardant layer 30 is 3-15 mm;
[0047] Further, the mass of 30 square meters of the second flame retardant layer is 130-330 g;
[0048] In the above scheme, if the thickness of the second flame retardant layer 30 is too thin, or its unit weight is too low, it will affect the flame retardant properties of the fabric, and ultimately may not meet the corresponding flame retardant standards, affecting the normal listing of the product. If the thickness of the fabric is too thick or the unit weight is too large, it will affect the product's texture and increase the cost.
[0049] Further, in some embodiments, the second flame retardant layer 30 is a flame retardant threaded cloth, and its mass per square meter is 160-260g; it is understandable that after further testing, the present application found that the use of flame retardant threaded cloth of this gram weight can balance excellent flame retardant properties while effectively controlling costs.
[0050] Specifically, the air layer 10 includes one of polyester fiber, high molecular ice silk, medium molecular ice silk, pure cotton, rayon, linen, and brass fiber.
[0051] Further, the thickness of the air layer 10 is 3-30 mm;
[0052] Furthermore, the mass of 10 square meters of the air layer is 160-520 g;
[0053] In the above solution, if the thickness of the air layer 10 is too thin, or its unit weight is too low, it may affect the texture of use; if the thickness of the fabric is too thick or the unit weight is too large, it will affect the texture of use of the product and increase the cost.
[0054] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.
[0055] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
