Example Embodiment

[0015] Example: such as Figure 1 ~ Figure 2 As shown, the present invention includes an aramid cloth substrate 1, a plurality of first ropes 2, a plurality of second ropes 3, and a plurality of third ropes 4. The first ropes 2 are arranged diagonally and parallel on the aramid cloth substrate 1. The two ropes 3 and the first rope 2 are arranged in parallel on the aramid cloth substrate 1 at a 90-degree clip. Each second rope 3 is arranged in a staggered manner with the first rope 2 up and down, and the third rope 4 is arranged horizontally and horizontally. On the second rope 3 and the first rope 2, the third rope 4 is parallel to each other, and the first rope 2, the second rope 3 and the third rope 4 form a plurality of lattice cavities, each of the first rope 2 The tail is connected to the head of the second rope 3 corresponding to the first rope 2, and the tail of the second rope 3 is connected to the head of the first rope 2 corresponding to the second rope 3. The first ...

Abstract

The invention discloses a three-dimensional aramid fiber felt and belongs to the thermal insulation field of firefighter uniforms. The three-dimensional aramid fiber felt comprises an aramid fiber cloth base body, a plurality of first ropes, a plurality of second ropes and a plurality of third ropes; the first ropes are obliquely arranged on the aramid fiber base body in a parallel mode; the second ropes are arranged on the aramid fiber base body in a parallel mode with angles with the first ropes; the second ropes and the first ropes are staggered up and down; the third ropes are crossly arranged on the second ropes and the first ropes horizontally; the third ropes are parallel to one another; the first ropes, the second ropes and the third ropes form a plurality of grid cavities. According to the three-dimensional aramid fiber felt, three layers of ropes are arranged on the aramid fiber cloth based on an original layer of aramid fiber cloth, then the grid cavities are formed in the aramid fiber cloth, an air layer is added to an interlayer of a firefighter uniform, the thermal insulation space of the firefighter uniform is increased, original three to four layers of aramid fiber cloth are replaced, and the weight and the cost of the firefighter uniform are reduced.

Description

technical field [0001] The invention belongs to the field of heat insulation of firefighting clothing, and in particular relates to a three-dimensional aramid felt used for heat insulation on firefighting clothing. Background technique [0002] Non-woven fabrics have been widely used in the market. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Features. The non-woven fabric is made into the interlayer of the fire suit, which can be used as a heat insulation layer, so that it can play the role of heat insulation and flame retardancy. With the increasing maturity of aramid non-woven fabric technology, the number of manufacturers producing non-woven fabrics is also increasing, and the sales of aramid non-woven fabrics are also becoming increasingly fierce. In order to improve the competitiven...
