This embodiment will be described in detail with reference to fig. 1 and 2. The fire-fighting fire-retardant sock comprises a sock body 1 and an elastic rib top 2. The sock body 1 is woven by adopting flame-retardant yarns 3. The cutting-resistant flame-retardant wires 3 are adopted for weaving. The elastic rib top 2 is formed by weaving elastic flame-retardant yarns, so that the elastic rib top has the flame-retardant effect

The flame-retardant yarn 3 includes a flame-retardant core yarn 31, a first covering layer 32, a second covering layer 33, and a third covering layer 34 from the inside to the outside. The first covering layer 32 is located outside the flame-retardant core yarn 31, the second covering layer 33 is located outside the first covering layer 32, and the third covering layer 34 is located outside the second covering layer 33.

Further, the first coating layer 32 is carbon fiber pre-oxidized filaments, and the fineness of the carbon fiber pre-oxidized filaments is 200D-400D, and 400D is selected in the embodiment. The carbon fiber pre-oxidized filaments are arranged in parallel and then wound on the outer side of the flame-retardant core yarn, and the flame-retardant core yarn is completely wrapped, so that the flame-retardant core yarn is not exposed. The carbon fiber pre-oxidized filament is propenyl primary carbonized pre-oxidized filament.

The inner layer of the flame-retardant core yarn 31 is a glass fiber filament, and the outer layer is coated with a carbon fiber and aramid 1414 short fiber blended fiber layer. The fineness of the flame-retardant core yarn 31 was 40 tex. The amount of the second coating layer 33 is 10-20 g, in this example 10 g, per km of the flame-retardant yarn 3. The amount of the third coating layer 34 is 15-25 g, in this example 25 g, per km of the flame-retardant yarn 3. The glass fiber filament used was 150D. The flame-retardant yarn 3 has the anti-cutting function by using the glass fiber filaments, so that the related socks have the anti-cutting and flame-retardant functions.

Further, the second coating layer 33 is aramid 1414 short fiber. The aramid 1414 short fibers have good insulating property and flame retardant property, and can improve the flame retardant effect of the socks. And the third coating layer 34 is made of flame-retardant viscose fiber or flame-retardant acrylic fiber, which is flame-retardant viscose fiber in the embodiment, and the specific specification is 38mm × 1.67 dtex. The flame-retardant viscose fiber used enables the flame-retardant yarn to have good hand feeling and wear resistance.

Furthermore, the elastic flame-retardant yarn comprises spandex filament and flame-retardant fibers coated on the outer side of the spandex filament. Namely, the core-spun yarn is prepared by taking spandex filament as core yarn and taking flame-retardant fiber as cladding fiber.

The elastic flame-retardant yarn can enable the elastic rib top 2 to have good elasticity.

In this embodiment, the flame-retardant core yarn 31 is a blended yarn of carbon fiber and aramid 1414 staple fiber. The carbon fiber and aramid 1414 short fibers enable the flame-retardant core yarn to have antistatic and flame-retardant effects.

Example two

Compared with the first embodiment, the fire-fighting fire-retardant sock related in the embodiment has the following differences:

the fineness of the carbon fiber pre-oxidized filaments used is 200D to 400D, selected to be 200D in this example.

The third coating layer 34 is made of flame retardant viscose fiber or flame retardant acrylic fiber, which is used in this embodiment and has a specification of 38mm × 1.67 dtex.

In this embodiment, the flame-retardant core yarn 31 is a core-spun yarn having an inner layer made of spandex filaments and an outer layer made of carbon fibers and aramid 1414 staple fibers. The spandex filament can be the anti-cutting flame-retardant yarn 3 and has elasticity on the premise of having a flame-retardant function. Can be better wrap up fire fighter's foot for fire fighter's convenience more when the motion.

The socks prepared from the cut-resistant flame-retardant yarns of the first and second examples were subjected to a cut-resistant test. The results of the Bladde Cut Resistance test by INTERTEK company are shown in the following table:
