Description

Technical Field

[0001] The present invention application relates to a multi-layer composite fabric for firefighters' firefighting protective clothing, which belongs to the field of personal protection for firefighters and is used for firefighters' protective clothing in emergency rescue scenarios at urban fire scenes. Background Art

[0002] In the field of firefighting, especially in the field of firefighters' firefighting protective clothing, firefighters' firefighting protective clothing currently mainly achieves multiple properties through multi-layer fabrics. According to the Chinese industry standard XF10-2014 "Firefighters' Firefighting Protective Clothing", the basic requirements for the outer layer are mainly flame retardant performance, thermal stability, shrinkage rate, surface moisture resistance, breaking strength, tearing strength, etc. The basic requirements for the waterproof and breathable layer are mainly flame retardant performance, thermal stability, shrinkage rate, hydrostatic pressure resistance, and moisture permeability performance. The basic requirements for the thermal insulation layer are mainly flame retardant performance, thermal stability, shrinkage rate, and the basic requirements for the comfort layer are mainly flame retardant performance, thermal stability, shrinkage rate, breaking strength, etc. In addition, the TPP of the thermal protection performance of the multi-layer fabric is not less than 28cal / cm 2 The weight of the finished garment shall not exceed 3.5kg. The main performance of firefighters' protective clothing includes safety and comfort. For example, the thermal protection performance TPP proposed by the Chinese industry standard XF10-2014 "Firefighters' Protective Clothing" is safety, while the moisture resistance proposed by the European standard EN469 "Firefighters' Protective Clothing" and the heat loss proposed by the American Fire Protection Association standard NFPA1971 "Building Fire Fighting Firefighters' Equipment" are thermal and moist comfort performance.

[0003] In the current reality, the most common firefighting protective clothing for firefighters include four-layer protective clothing, three-layer protective clothing, and two-layer protective clothing. The four-layer protective clothing includes an outer layer, a waterproof and breathable layer, a thermal insulation layer, and a comfort layer. The four layers are connected by sewing at the end, and at the same time, there is an internal air layer between each layer. In order to ensure the thermal protection performance TPP of the multi-layer fabric, the outer layer is usually a single-layer short-fiber woven fabric; the waterproof and breathable layer is a non-woven fabric coated fabric blended with short fibers such as aramid, the thermal insulation layer is a non-woven fabric blended with short fibers such as aramid, and the comfort layer is a woven fabric made of aramid viscose. The main problem with the four-layer protective clothing is that it is heavy, generally reaching more than 3.1kg, and the moisture resistance parameter in terms of thermal comfort is as high as 25m 2 Pa / W, this data is too high to be conducive to sweating, while the heat loss parameter is as low as 300W / m 2 , this data is too low and is not conducive to eliminating heat storage.

[0004] For three-layer protective clothing, including the outer layer, the waterproof, breathable and heat-insulating layer, and the comfort layer, the three layers are connected by sewing at the end, and there are air layers between the layers; in order to ensure the thermal protection performance of the TPP multi-layer fabric, the outer layer is usually a double-layer fabric, that is, the outer layer yarn is meta-aramid staple fiber, the outer layer bottom yarn is para-aramid filament, and the waterproof, breathable and heat-insulating layer is a non-woven fabric blended with aramid and other short fibers covered with a waterproof and breathable membrane; in addition, there is a comfort layer of woven fabric blended with aramid and viscose. Although the weight of the three-layer protective clothing is as low as 2.9kg, there are still the following problems: the bottom yarn of the outer layer is a filament fabric with a smooth surface, and it is difficult to improve the thermal protection performance by attaching silicone rubber to the surface of the outer layer filament fabric. At the same time, its thermal and moist comfort still needs to be improved, and the moisture resistance parameter has reached 20m 2 Pa / W, the lower the data, the better for sweating, and the heat loss parameter is as low as 310W / m 2 ,,This data is still too low to eliminate heat storage.

[0005] For two-layer protective clothing, including an outer layer and a waterproof, breathable, heat-insulating and comfortable layer, the two layers are connected by sewing at the end, and there is an air layer between the two layers. In order to ensure the thermal protection performance of the multi-layer fabric TPP, the outer layer is usually a double-layer fabric, the outer veil is meta-aramid staple fiber, etc., and the outer bottom yarn is para-aramid filament; the waterproof, breathable layer and heat-insulating and comfortable layer are often in the form of aramid or polyimide woven fabric with a raised wave structure or a honeycomb structure and a composite polytetrafluoroethylene film. Two-layer protective clothing is relatively uncommon. Although its weight is as low as 2.7kg, it still has the following problems: the bottom yarn of the outer layer is a filament fabric with a smooth surface, and it is difficult to improve the thermal protection performance by attaching silicone rubber to the surface of the outer filament fabric; at the same time, its thermal and moist comfort still needs to be improved, and the moisture resistance parameter has reached 17m 2 Pa / W, the lower the data, the better for sweating, and the heat loss parameter is as low as 320W / m 2 , this data is too low and is not conducive to eliminating heat storage.

[0006] Based on the above content, if the outer layer is in the form of a single-layer staple fiber woven fabric, although the thermal protection performance can be improved by attaching silicone rubber dots on the surface of the staple fiber fabric, the dots close to the inner side of the outer layer are easily damaged by various external friction forces during long-term use; if the outer layer is in the form of a double-layer staple fiber woven fabric, although the thermal protection performance can be improved by attaching silicone rubber dots on the surface of the staple fiber fabric, the thermal protection performance of this two-layer staple fiber woven fabric is still relatively low as a whole, and more and higher dots are required to further improve the thermal protection, but this also causes a further increase in weight.

[0007] Some researchers have proposed "202210619337.5, a double-layer membrane firefighter firefighting protective clothing". This patent includes an outer layer with an inner film and a waterproof and breathable layer with a woven fabric film. Two layers of composite fabrics still need to be cut twice during processing. Other researchers have proposed "202411271417.1, a comfortable and breathable firefighter firefighting protective clothing". This patent application has five layers of fabrics: outer layer, waterproof and breathable layer, waterproof and breathable layer, insulation layer, and comfort layer. It needs to be cut five times during processing. Both of the above patents have the problem of low processing efficiency of clothing, and the weight is heavy, which increases the burden weight of firefighters, increases the physical energy consumption of firefighters, and reduces the combat efficiency of firefighters. In particular, the patent application 202411271417.1 adopts a double-layer membrane five-layer fabric design, and the air layer in the middle of each layer of fabric further reduces the overall heat loss, which is not conducive to the heat storage and discharge of firefighters, thereby reducing the thermal and humid comfort of firefighters. Summary of the invention

[0008] In view of the problems of heavy weight, high moisture resistance, low heat loss and low processing efficiency caused by multi-layer fabrics in the prior art, the present invention proposes a multi-layer composite fabric for firefighters' fire-fighting protective clothing, which can meet the waterproof and heat insulation protection performance requirements of relevant standards while having lower moisture resistance and higher heat loss, while improving processing efficiency. In addition, the composite fabric also has increased antibacterial and far-infrared properties, thereby facilitating the long-term health of firefighters.

[0009] The technical solution adopted by the present invention is: a multi-layer composite fabric for firefighters' firefighting protective clothing, which is composed of a finishing agent, an outer layer, glue dots, a waterproof and breathable layer and a comfort layer.

The comfort layer is bonded to the other side of the waterproof and breathable layer. The outer layer is composed of a layer of veil and multiple layers of bottom yarn; the veil is a short fiber fabric; the bottom yarn is a filament fabric or a filament fabric and a short fiber fabric; The finishing agent is used to improve the surface moisture resistance of the outer layer and achieve waterproof and moisture-resistant functions; The outer layer is used to resist flames and radiation and protect firefighters from physical damage; Glue is used to match the outer layer and the waterproof breathable layer) to enhance the air layer effect; The waterproof and breathable layer is used to improve water resistance and achieve waterproof and anti-seepage functions; The comfort layer is used to contact the firefighter's skin and has certain flame retardant properties and thermal stability.

[0010] The outer layer is composed of a woven bottom yarn I of 15%-30% short fiber fabric, a bottom yarn II of 15%-30% short fiber fabric and a bottom yarn I of 15%-25% filament fabric on one side of a veil I of 20%-50% short fiber fabric.

[0011] The outer layer is composed of a woven bottom yarn II of 15%-30% filament fabric, a bottom yarn III of 15%-30% short fiber fabric and a bottom yarn III of 15%-25% filament fabric on one side of a veil II of 20%-50% short fiber fabric.

[0012] The outer layer is composed of a woven bottom yarn IV of 15%-30% short fiber fabric, a bottom yarn IV of 15%-30% filament fabric and a bottom yarn V of 15%-25% filament fabric on one side of a veil III of 20%-50% short fiber fabric.

[0013] The outer layer is composed of a woven yarn IV of 20%-50% short fiber fabric, a bottom yarn VI of 15%-30% filament fabric, a bottom yarn VII of 15%-30% filament fabric and a bottom yarn VIII of 15%-25% filament fabric in sequence.

[0014] The outer layer is composed of a woven yarn V of 25%-50% short fiber fabric, a bottom yarn IX of 20%-40% filament fabric and a bottom yarn X of 20%-40% filament fabric in sequence.

[0015] The outer layer is composed of a woven bottom yarn V of 20%-40% short fiber fabric and a bottom yarn XI of 20%-40% filament fabric, which are arranged on one side of a face yarn VI of 25%-50% short fiber fabric.

[0016] The waterproof and breathable layer is a two-layer structure consisting of a polytetrafluoroethylene film sprayed with an oil-repellent film.

[0017] The comfort layer, the face veil I of staple fiber fabric, the base yarn I of staple fiber fabric, the base yarn II of staple fiber fabric, the face veil II of staple fiber fabric, the face veil III of staple fiber fabric, the base yarn III of staple fiber fabric, the base yarn IV of staple fiber fabric, the face veil IV of staple fiber fabric, the face veil V of staple fiber fabric, the face veil VI of staple fiber fabric and the base yarn V of staple fiber fabric are all obtained from the following raw materials in weight percentage: Meta-aramid staple fiber 20%-95%, Para-aramid staple fiber 5%-70%, Polyimide staple fiber 0%-70%, Conductive fiber 0%-15%, PBI short fiber 0%-50%, PBO short fiber 0%-50%.

[0018] The base yarn I, base yarn II, base yarn III, base yarn IV, base yarn V, base yarn VI, base yarn VII, base yarn VIII, base yarn IX, base yarn X and base yarn XI of the filament fabric are all obtained from the following raw materials in weight percentage: Para-aramid filament 0%-100%, Polyimide filament 0%-100%, Basalt filament 0%-100%, PBO filament 0%-100%.

[0019] The beneficial effects of the present invention are as follows: the structure is a multi-layer composite fabric integrated into one, which is suitable for emergency rescue scenes in urban firefighting fires, meets the thermal stability requirements of 260°C, and can achieve the following multiple properties: First, while ensuring safety performance, the multi-layer composite fabric has the characteristic of more efficient cutting operation: the multi-layer composite fabric can replace the multi-layer fabric of the existing firefighter fire-fighting protective clothing, such as the four-layer fabric of the outer layer, the waterproof breathable layer, the thermal insulation layer, and the comfort layer, or the three-layer fabric of the outer layer, the waterproof breathable and thermal insulation layer, and the comfort layer, or the two-layer fabric of the outer layer, the waterproof breathable and thermal insulation and comfort layer. The multi-layer composite fabric achieves excellent thermal protection performance through the coordinated optimization of the effect of the external air layer in contact with the skin, thereby ensuring the fire safety of firefighters; the multi-layer composite fabric can be formed into a garment after only one cutting process when processing into garments, which is more efficient than the four-time cutting process of the traditional four-layer clothing, the three-time cutting process of the three-layer clothing, and the two-time cutting process of the two-layer clothing.

[0020] Second, the new fabric has better moisture resistance parameters and perspiration effect: compared with traditional two-layer, three-layer, and four-layer multi-layer fabrics, this multi-layer composite fabric has lower moisture resistance, thinner thickness, and less internal air spacing, so it can discharge sweat vapor faster, which in turn helps perspiration and achieves better thermal and moisture comfort.

[0021] Third, the new fabric has more excellent heat loss parameters and heat dissipation effect: compared with traditional two-layer, three-layer, and four-layer multi-layer fabrics, this multi-layer composite fabric has higher heat loss, thinner thickness, and less internal air spacing, so it can discharge the heat stored in the body faster, which in turn helps to discharge the stored heat, thereby achieving better thermal and moisture comfort.

[0022] Fourth, the clothing equipment formed by the new fabric is lighter: this multi-layer composite fabric can have a relatively lower weight while ensuring the waterproof and heat-insulating protection performance requirements of the relevant standards, such as 2.6kg, which is much lower than the standard requirement of 3.5kg, 3.1kg of traditional four-layer clothing, 2.9kg of three-layer clothing, and 2.7kg of two-layer clothing. Therefore, it helps to reduce the burden weight of firefighters and maintain their combat efficiency.

[0023] Fifth, the new fabric has the health benefits of antibacterial and far-infrared properties: This multi-layer composite fabric increases its antibacterial and far-infrared properties by introducing inherently antibacterial polyimide fibers. Its initial antibacterial rate is as high as 99%, and the antibacterial rate after long-term use can reach more than 85%. At the same time, it has a certain emissivity in far-infrared performance, which facilitates the long-term occupational health of firefighters.

[0024] In short, this multi-layer composite fabric can replace the outer layer, waterproof and breathable layer, thermal insulation layer, and comfort layer of the existing firefighter fire-fighting protective clothing, and at the same time solves the problem that filament fabrics are difficult to adhere to silicone rubber dispensing.
