Description

Technical Field

[0001] The invention relates to the technical field of arc-proof fabrics, and in particular to a light-colored ultra-high arc-proof fabric and application thereof. Background Art

[0002] Electric arc is a gas discharge phenomenon. When the body is close to high voltage electricity (without contact), the body's induction acts as a bridge to form a jump. The instantaneous temperature generated can reach 2000℃, and it instantly triggers high energy accumulation. The high heat of the arc instantly heats the air and produces a high-temperature airflow shock wave, causing serious damage to the human body.

[0003] Arc-proof fabrics have good mechanical strength and explosion resistance, and are also heat-resistant, flame-retardant, non-combustible, non-melting, and electrically insulating. At present, under the premise of the same gram weight, the arc-proof values ​​of arc-proof fabrics of different colors vary greatly. The arc-proof values ​​of dark colors are higher, while the arc-proof values ​​of light colors are lower, and may even be halved.

[0004] Therefore, the arc protection value of light-colored arc-proof fabrics is generally improved by increasing the fabric weight or compounding materials with better heat resistance. However, the increase in weight often leads to poor moisture permeability and air permeability of the fabric, which can easily cause the wearer to feel stuffy, and the heavy clothing will also cause inconvenience to people's movements.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] One of the purposes of the present invention is to provide a light-colored ultra-high arc protection fabric that can have the characteristics of better flame retardant performance, ultra-high arc protection value and wearing comfort under the premise of lower gram weight.

[0020] Furthermore, the multifunctional felt is a multifunctional felt wrapped with a waterproof and breathable film;

[0025] Furthermore, the weight of the inner layer fabric is 110 g / m 2 .

[0026] Furthermore, the layers of the light-colored ultra-high arc protection fabric are bonded together with flame-retardant adhesive to form a whole.

[0027] Furthermore, the gram weight of the light-colored ultra-high arc protection fabric is 300-420g / m 2 .

[0028] Furthermore, the arc protection value of the light-colored ultra-high arc protection fabric is above 60cal.

[0029] In a second aspect, a light-colored ultra-high arc protection fabric as described in any of the above items is used in protective functional clothing.

[0040] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] According to a first aspect of the present invention, there is provided a light-colored ultra-high arc protection fabric, which comprises, from the outside to the inside, a surface fabric, a middle layer of multifunctional felt, and an inner fabric;

[0042] Among them, the surface fabrics include but are not limited to light-colored surface fabrics;

[0043] The surface fabric is made of interwoven surface yarns;

[0044] The surface yarn includes yarn A and yarn B;

[0045] Yarn A comprises flame retardant nitrile chlorofiber, phase change fiber, silicon nitrogen series non-melting flame retardant nylon and polyaromatic oxadiazole fiber blended in a mass ratio of 40-60:20-30:5-15:5-15, and its typical but non-limiting mass ratios are, for example, 40:30:15:15, 50:20:15:15, and 60:30:5:5;

[0046] Yarn B comprises a yarn blended with meta-aramid fiber and polyaromatic oxadiazole fiber in a mass ratio of 50-70:30-50, and a typical but non-limiting mass ratio thereof is, for example, 50:50, 55:45, 60:40, 65:35, 70:30;

[0047] Among them, multifunctional felt includes but is not limited to dark multifunctional felt;

[0048] The preparation method of the multifunctional felt comprises the following steps:

[0049] Black phosphorus-based flame-retardant viscose fiber, black polyaromatic oxadiazole fiber, black phase change fiber and flame-retardant polyester fiber are mixed in a mass ratio of 40-50:10-20:10-20:10-20 (typical but non-limiting mass ratios are, for example, 40:20:20:20, 45:15:20:20, 50:20:10:20), and then laid and spunlace or needle-punched to obtain a non-woven felt, which is then immersed in an aerogel emulsion and dried to obtain a functional felt.

[0050] The light-colored ultra-high arc protection fabric provided by the present invention is a fabric formed by a composite of multiple fabrics, and includes, from the outside to the inside, a surface fabric, a multifunctional felt in the middle layer, and an inner fabric, wherein the yarn in the surface fabric includes yarn A and yarn B blended with specific components, wherein the yarn A mainly plays the role of flame retardancy and heat absorption and energy storage, and the heat absorption property of the phase change fiber can effectively reduce the energy penetrating the fabric, thereby improving the arc protection value of the fabric in disguise; the main function of the yarn B is flame retardancy and high temperature resistance, and it also plays the role of supporting the fabric skeleton, and the heat shrinkage rate of the yarn B when heated is very small; in addition, when heated, the yarn A will produce a Yarn A expands and contracts to a certain extent, while yarn B basically does not shrink, which will help to form many air pockets. Air is a poor conductor of heat, thereby further effectively improving the arc protection value of the fabric. When heated, the aerogel on the multifunctional felt in the middle layer has good thermal insulation performance. On this basis, the heat absorption and energy storage of the phase change fiber in the multifunctional felt and the absorption of arc light by the black felt can effectively improve the arc protection performance. Moreover, the phosphorus-based flame retardant viscose and polyaromatic oxadiazole fibers will expand when heated, making the aerogel felt denser, further improving the thermal insulation performance, and indirectly improving the arc protection performance.

[0051] Therefore, through the superposition of the above-mentioned different functional fabric layers, the light-colored ultra-high arc protection fabric of the present invention can have better flame retardant properties and ultra-high arc protection value under the premise of lower gram weight, and its arc protection value can reach more than 60cal, far exceeding the Level 4 standard of DL320-2019 (greater than 40cal). At the same time, compared with the various existing arc protection fabrics, the arc protection fabric of the present invention is more comfortable to wear due to its lower gram weight and thinness, thereby realizing an effective combination of multi-functional protection and wearing comfort.

[0052] In a preferred embodiment, the multifunctional felt of the present invention is a multifunctional felt wrapped with a waterproof and breathable membrane. Since the air permeability of the aerogel on the multifunctional felt is poor, the present invention forms a stepped unidirectional moisture conduction function by adding moisture-absorbing and quick-drying fibers (flame-retardant polyester fibers) to the multifunctional felt and compounding a waterproof and breathable membrane, thereby improving the wearing comfort of the fabric.

[0053] A typical structure of a light-colored ultra-high arc protection fabric, such as Figure 1 As shown, from outside to inside are the surface fabric, waterproof and breathable membrane, multifunctional felt, waterproof and breathable membrane and inner fabric;

[0054] The surface fabric is interwoven by yarn A and yarn B, and the weight of the surface fabric can be 150-220g / m 2 , for example, it can be 150g / m 2 , 160g / m 2 , 170g / m 2 , 180g / m 2 , 190g / m 2 , 200g / m 2 , 210g / m 2 , 220g / m 2 , but not limited to this, the surface fabric mainly plays the role of flame retardant, energy storage and heat insulation;

[0055] Yarn A and yarn B can be interwoven in a ratio of 3:1 to form the structure of the surface fabric. Figure 2 , where white represents yarn A and black represents yarn B. The unique structure of the surface fabric will form an air layer when heated. Figure 3 , which can further improve the arc protection value of the surface fabric. The specific process of the air layer formation is that when heated, yarn A will expand and shrink to a certain extent, while yarn B basically does not shrink, thus forming many air pockets on the surface fabric. Figure 4 , air is a poor conductor of heat, thus further improving the arc protection value of the fabric;

[0056] The waterproof and breathable film wraps the multifunctional felt, and the two together play the role of ultra-high heat insulation, heat absorption and moisture permeability. The weight of the multifunctional felt can be 60-120g / m 2 , for example, it can be 60g / m 2 , 70g / m 2 , 80g / m 2 , 90g / m 2 , 100g / m 2 , 110g / m 2 , 120g / m 2, but not limited to this, the aerogel on it can play a good role in heat insulation, the phase change fiber inside can absorb heat and store energy, and the dark (black) felt can also absorb arc light, thereby effectively improving the arc protection function of the fabric, and the phosphorus flame retardant viscose and polyaromatic oxadiazole fibers in the multifunctional felt will expand when heated, making the aerogel felt denser, such as Figure 5 As shown, the thermal insulation performance is further improved, and the arc protection performance of the fabric is indirectly improved;

[0057] The inner layer fabric of the invention mainly plays the role of flame retardancy, moisture permeability and comfortable wearing.

[0058] In a preferred embodiment, the inner layer fabric of the present invention includes but is not limited to dark inner layer fabric;

[0059] The inner fabric is woven from the inner yarn;

[0060] Among them, the inner layer yarn includes black meta-aramid fiber, black flame retardant viscose fiber and black flame retardant polyester fiber blended in a mass ratio of 30-50:20-40:20-30, and its typical but non-limiting mass ratios are, for example, 30:40:30, 40:30:30, 45:35:20, and 50:20:30.

[0061] The inner layer fabric of the present invention is woven from inner layer yarns, which are blended with black meta-aramid, black flame-retardant viscose and black moisture-absorbing quick-drying flame-retardant polyester fibers according to a specific mass ratio. The inner layer fabric mainly plays the role of flame retardancy and comfort, and its gram weight can be 110g / m 2 , but not limited to this.

[0062] In a preferred embodiment, the layers of the light-colored ultra-high arc protection fabric of the present invention are bonded together by flame retardant adhesive to form a whole, and the gram weight can be 300-420g / m 2 , for example, it can be 300g / m 2 , 320g / m 2 , 340g / m 2 , 360g / m 2 , 380g / m 2 , 400g / m 2 , 420g / m 2 , but not limited to this.

[0063] In a preferred embodiment, the arc protection value of the light-colored ultra-high arc protection fabric of the present invention is above 60 cal.

[0064] The light-colored ultra-high arc-proof fabric of the present invention is a multi-layer fabric composite structure. Through the combination of different functional yarns, different yarn materials, appropriate material ratios and unique organizational structures, the fabric not only has ultra-high arc-proof function under the superposition of different functional layers, but also has the characteristics of being light, flame-retardant and comfortable to wear; the light-colored ultra-high arc-proof fabric of the present invention has an arc-proof value of more than 60cal under the premise of a gram weight of 380 grams, which is far more than the level 4 standard of DL320-2019 (greater than 40cal). Due to the low gram weight of the fabric, compared with various existing arc-proof fabrics, the fabric of the present invention is more comfortable to wear, and realizes an effective combination of multi-functional protection and wearing comfort.

[0065] According to a second aspect of the present invention, there is provided a use of the light-colored ultra-high arc protection fabric described in any one of the above items in protective functional clothing.

[0066] In a preferred embodiment, the protective functional clothing of the present invention includes but is not limited to arc protection clothing.

[0067] The application of the light-colored ultra-high arc protection fabric provided by the present invention can achieve an effective combination of multifunctional protection and wearing comfort, and has an outstanding application effect.

[0099] Example 8

[0100] The difference between this embodiment and embodiment 1 is that the inner yarn in this embodiment is a yarn blended with black meta-aramid fiber, black flame-retardant viscose fiber and black flame-retardant polyester fiber in a mass ratio of 40:30:30, and the rest is the same as embodiment 1, and the arc protection value of the obtained arc-proof fabric is 67cal.

[0101] Example 9

[0102] The difference between this embodiment and embodiment 1 is that the inner yarn in this embodiment is a yarn blended with black meta-aramid fiber, black flame-retardant viscose fiber and black flame-retardant polyester fiber in a mass ratio of 50:20:30, and the rest is the same as embodiment 1, and the arc protection value of the obtained arc-proof fabric is 69cal.

[0103] Comparative Example 1

[0104] The difference between this comparative example and Example 1 is that the yarn A in this comparative example is a yarn blended with flame-retardant nitrile chlorinated fiber, phase change fiber, silicon nitrogen series non-melting flame-retardant nylon and polyaromatic oxadiazole fiber in a mass ratio of 30:40:10:20, and the rest is the same as Example 1, and the arc protection value of the obtained arc-proof fabric is 53cal;

[0105] Compared with the arc-proof fabric in Example 1, the arc-proof fabric in this comparative example has the defect that the content of flame-retardant nitrile chlorofiber is less than the flame-retardant critical value, and the content of non-flame-retardant fiber is relatively high, resulting in a decrease in the flame-retardant thermal protection value of the fabric.

[0106] Comparative Example 2

[0107] The difference between this comparative example and Example 1 is that the yarn A in this comparative example is a yarn blended with flame-retardant nitrile chlorofiber, phase change fiber, silicon nitrogen series droplet-free flame-retardant nylon and polyaromatic oxadiazole fiber in a mass ratio of 70:10:10:10, and the rest is the same as Example 1, and the arc protection value of the obtained arc-proof fabric is 57 cal;

[0108] Compared with the arc-proof fabric in Example 1, the defect of the arc-proof fabric in this comparative example is that the content of thermal stability fiber is too high, which causes the fabric to shrink severely when exposed to heat and even to have small holes, resulting in poor thermal protection.

[0109] Comparative Example 3

[0110] The difference between this comparative example and Example 1 is that the yarn A in this comparative example is a yarn blended with phase change fiber, silicon nitrogen series droplet-free flame-retardant nylon and polyaromatic oxadiazole fiber in a mass ratio of 50:20:30, and the rest is the same as Example 1, and the arc protection value of the obtained arc-proof fabric is 32cal;

[0111] Compared with the arc-proof fabric in Example 1, the defects of the arc-proof fabric in this comparative example are that the flame retardant and thermal protection of the surface fabric is very poor, the surface fabric is flammable, and the overall thermal protection of the fabric is greatly reduced.

[0112] Comparative Example 4

[0113] The difference between this comparative example and Example 1 is that the surface fabric in this comparative example only includes yarn B (does not include yarn A), and the rest is the same as Example 1, and the arc protection value of the obtained arc-proof fabric is 56 cal;

[0114] Compared with the arc-proof fabric in Example 1 (the proportion of flame-retardant nitrile chlorofiber is within a certain range, it will expand and contract when heated, and will form an air layer when combined with yarn B, thereby improving the thermal insulation effect, and the phase change fiber has a good heat absorption and energy storage effect, which can reduce the heat passing through the fabric), the defect of the arc-proof fabric in this comparative example is that the arc protection value is reduced, and the light-colored fabric containing only yarn B has a very poor sun exposure effect, which is much lower than the fabric with flame-retardant nitrile chlorofiber as the main component.

[0115] Comparative Example 5

[0116] The difference between this comparative example and Example 1 is that the mixing mass ratio of black phosphorus flame retardant viscose, black polyaromatic oxadiazole, black phase change fiber and moisture-absorbing quick-drying flame retardant polyester fiber in the multifunctional felt of this comparative example is 30:30:30:10, and the rest is the same as Example 1, and the arc protection value of the obtained arc-proof fabric is 55cal;

[0117] Compared with the arc-proof fabric in Example 1, the arc-proof fabric in this comparative example has the defect that the fabric is flammable and the flame-retardant and heat-insulating protective effects are reduced.

[0118] Comparative Example 6

[0119] The difference between this comparative example and Example 1 is that the multifunctional felt of this comparative example does not contain black phosphorus flame-retardant viscose and black polyaromatic oxadiazole, but only contains black phase change fiber and moisture-absorbing quick-drying flame-retardant polyester fiber (the mixing mass ratio of the two is 50:50), and the rest is the same as Example 1, and the arc protection value of the obtained arc-proof fabric is 28cal;

[0120] Phase change fiber is a non-flame retardant fiber. The higher its proportion, the worse the flame retardant performance of the fabric. If the proportion of flame retardant polyester fiber is too high, the fabric will have melt droplets when exposed to high temperature, causing secondary damage to the human body. Therefore, compared with the arc-proof fabric in Example 1, the defect of the arc-proof fabric in this comparative example is that its flame retardant and heat-insulating performance is very poor, and it basically loses its flame retardant and heat-insulating effect.

[0121] Comparative Example 7

[0122] The difference between this comparative example and Example 1 is that the multifunctional felt in this comparative example is a light-colored multifunctional felt, and the inner layer fabric is a light-colored inner layer fabric. Compared with the arc-proof fabric in Example 1, the defect of the arc-proof fabric in this comparative example is that the arc-proof value is lower (the arc-proof value of dark colors is higher, while the arc-proof value of light colors is lower, and may even be halved).

[0123] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
