Description
Technical field
The utility model belongs to the heat insulation field of fire-entry suit, especially relevant with the three-dimensional aramid felt of heat insulation use on a kind of fire-entry suit.
Background technology
Nonwoven finds broad application on market, and it is environment-friendly materials of new generation, has protection against the tide, ventilative, pliable and tough, light weight, not combustion-supporting, easy decomposition, nontoxic nonirritant, rich color, the feature such as use again cheap, capable of circulation.Nonwoven is produced in the interlayer of fire-entry suit, can makes thermal insulation layer and use, thereby can play the effects such as heat insulation, fire-retardant.Increasingly mature along with aramid fiber nonwoven technology, the producer that produces nonwoven is also increasing, the sale of aramid fiber nonwoven is also growing more intense, in order to improve the competitiveness of this product, also for making firefighter uniform, reduce costs, the existing nonwoven for fire-entry suit only designs one deck conventionally, and the effect of heat insulation that still only designs layer of non-woven fabric is not good.If need to improve the effect of heat insulation of fire-entry suit, just need to be by increase again the nonwoven of two to three layers in the interlayer of fire-entry suit, yet the number of plies that increases nonwoven has just increased the cost of fire-entry suit, and has increased the weight of fire-entry suit, fireman is middle inconvenience in action.
Utility model content
The purpose of this utility model is to provide the three-dimensional aramid felt of heat insulation use on a kind of fire-entry suit, and the utility model has solved the defect that fire-entry suit thermal insulation layer effect of heat insulation is not good, the number of plies of stack nonwoven causes the weight of fire-entry suit to increase.
For this reason, the utility model is by the following technical solutions: three-dimensional aramid felt, comprise aramid fiber cloth matrix, it is characterized in that, described three-dimensional aramid felt also comprises many first ropes, many the second ropes and Duo Gen the 3rd rope, the first rope oblique parallel is arranged on aramid fiber cloth matrix, the second rope and the first rope are parallel on aramid fiber cloth matrix at angle, every the second rope is staggered up and down with the first rope respectively, the 3rd described rope transverse horizontal is arranged on described the second rope and the first rope, between the 3rd rope, be parallel to each other, the first rope, between the second rope and the 3rd rope, form a plurality of grid cavitys, owing to having increased by three layers of rope at aramid fiber cloth cover, on the basis of aramid fiber cloth matrix, formed sound of laughing a cavity, utility model is applied in the interlayer of fire-entry suit, making has increased air layer in the interlayer of fire-entry suit, thereby increased the insulated space of fire-entry suit, made the effect of heat insulation of the clothes made better.
As to technique scheme supplement and perfect, the utility model also comprises following technical characterictic.
The second described rope and the first rope are 90 degree angles.
The second described rope and the first rope are 45 degree angles.
The head of the second rope that the afterbody of the first described rope is corresponding with this first rope connects, the head of the first rope that the afterbody of this second rope is corresponding with this second rope connects, so circulation, thereby make each first rope and the second rope form integral type, increase the aesthetic property of aramid fiber cloth matrix, and arrange simply, reducing the cutting step of rope, the 3rd described rope is arranged and is formed by a rope.
The first described rope, the second rope and the 3rd rope are that aramid fiber braiding forms.As preferably, described aramid fiber is aramid fiber 1313 or Fanglun l414.
The first described rope, the second rope and the 3rd rope by suturing with thread management on described aramid fiber cloth matrix, thereby can make rope be fixed on aramid fiber cloth matrix, and increased third dimension of the present utility model; As preferably, the material of described line adopts high-tenacity polyethylene fibre.
Use the utility model can reach following beneficial effect: the utility model by setting up three layers of rope on aramid fiber cloth on the basis at original one deck aramid fiber cloth, thereby on aramid fiber cloth, form sound of laughing a grid cavity, aramid fiber cloth has increased air layer in the interlayer of fire-entry suit, increased the insulated space of fire-entry suit, substituted this first three to the aramid fiber cloth of four layers, alleviated weight and the cost of fire-entry suit.

Fig. 2 is schematic perspective view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
Embodiment: as shown in Fig. 1～Fig. 2, the utility model comprises aramid fiber cloth matrix 1, many the first ropes 2, many the second ropes 3 and Duo Gen the 3rd rope 4, the first rope 2 oblique parallels are arranged on aramid fiber cloth matrix 1, 2 one-tenth 90 degree folder degree of the second rope 3 and the first rope are parallel on aramid fiber cloth matrix 1, every the second rope 3 is staggered up and down with the first rope 2 respectively, the 3rd rope 4 transverse horizontal are arranged on described the second rope 3 and the first rope 2, between the 3rd rope 4, be parallel to each other, the first rope 2, between the second rope 3 and the 3rd rope 4, form a plurality of grid cavitys, the head of the second rope 3 that the afterbody of the first rope 2 is corresponding with this first rope 2 connects, the head of the first rope 2 that the afterbody of this second rope 3 is corresponding with this second rope 3 connects, so circulation, thereby make each first rope 2 and the second rope 3 form integral type, increased the aesthetic property of aramid fiber cloth matrix, and arrange simple, reduce the cutting step of rope, the 3rd rope 4 is arranged and is formed by a rope, as preferably, the first rope 2, the second rope 3 and the 3rd rope 4 adopt Fanglun l414 to make and form, aramid fiber rope is to be formed by cutting twisting by aramid fiber nonwoven, Fanglun l414 is a kind of fiber of high-fire resistance, can meet the high temperature of 200 ℃～250 ℃, vitrification point is more than 300 ℃, heat decomposition temperature is up to 560 ℃, fibre strength 0.215 newton/dawn, modulus 4.9～9.8 newton/dawn, specific strength is 5 times of steel, adopt this raw material, the unit are fracture strength of nonwoven: [warp-wise+broadwise fracture strength (N)]/mass area ratio (g) >=5, and the thermal stability probe temperature of nonwoven can be brought up to 260 ℃ ± 10 ℃, the first rope 2, the second rope 3 and the 3rd rope 4 are sewn on described aramid fiber cloth matrix 1 by needlework, the material selection high-tenacity polyethylene fibre of these needlework, and the feature of high-tenacity polyethylene fibre is that intensity is high, is as the good material of sewing thread.When the utility model is made, first nonwoven is formed to aramid fiber rope by cutting twisting, then by sewing machine by aramid fiber rope automatic sewing on aramid fiber cloth matrix, after stitching completes, aramid felt is tested, inspected rear coiling, complete the making of aramid felt, the utility model can complete processing by plant equipment, is conducive to implementation of the present utility model and production.
The utility model increases by three layers of rope at the matrix of aramid fiber cloth cover, thereby on the basis of aramid fiber cloth matrix, formed sound of laughing a cavity, the utility model is applied in the interlayer of fire-entry suit, making has increased air layer in the interlayer of fire-entry suit, thereby increased the insulated space of fire-entry suit, make the effect of heat insulation of the clothes made better, and alleviated weight and the cost of fire-entry suit.
