The patent with the application number: 201610294715.1 discloses "An explosion-proof underwear and its preparation method and application". The underwear is divided into two layers, the inner layer is a silk layer, and the outer layer is an aramid fiber layer. Yes, the heat and humidity comfort should be satisfied to the greatest extent. Silk fabrics are not only expensive, but the outer layer and aramid layer will affect heat dissipation
Due to its high strength, high modulus, low density, low thermal expansion coefficient, and good fatigue resistance, aramid fiber maintains stable dimensions and properties in the range of -192 to 182 °C, and does not burn or melt; it is currently the most commonly used fire protection Clothing fabric, but its spinnability is poor, high-count yarn is difficult to form, its initial modulus is high, rigidity is high, moisture absorption is poor, and the degree of fit with the human body is poor, wearing itching, poor comfort, so currently aramid is used as fire-fighting underwear less

Abstract

The invention discloses a firefighter underwear. The firefighter underwear comprises an underwear front piece and an underwear rear piece which are connected by sewing, wherein the underwear front piece comprises first fabric with high sweat-absorbent ability, first fabric with low sweat-absorbent ability and first protective fabric; the underwear rear piece comprises second fabric with high sweat-absorbent ability, second low fabric with low sweat-absorbent ability and second protective fabric; both the first fabric with high sweat-absorbent ability and second fabric with high sweat-absorbentability consist of aramid fibers wound with bamboo fabrics; both the first fabric with low sweat-absorbent ability and second fabric with low sweat-absorbent ability consist of aramid fibers wound with polypropylene fabric; and both the first protective fabric and the second protective fabric consist of aramid fibers. The firefight underwear uses hot-humid comfortable fabric in an area at which afirefighter is liable to perspire, and improves wearing comfort. A protective area is set in an important area of a human body, protective fabric is fixedly connected onto the firefighter underwear locally in a spaced mode to increase a gap between a protective material and firefighter underwear, so that air convection is convenient, and perspiration is facilitated.

Description

technical field [0001] The invention relates to the technical field of functional underwear, in particular to a fire-fighting underwear. Background technique [0002] Firefighting clothing is one of the important equipment to protect the personal safety of firefighters who are active on the front line of firefighting. It is not only an indispensable item in the fire rescue scene, but also a fireproof appliance to protect firefighters from injury. Therefore, firefighters need to rely on fire suits to protect themselves in their daily work, so there are many studies on improving the performance and functions of fire suits. [0003] The underwear worn by firefighters is generally based on ordinary clothes. The patent with the application number: 201610294715.1 discloses "An explosion-proof underwear and its preparation method and application". The underwear is divided into two layers, the inner layer is a silk layer, and the outer layer is an aramid fiber layer. Yes, the heat...
