[0002] Fire suits are one of the important equipment to protect the personal safety of firefighters.
[0003] At present, firefighting uniforms are usually made of ① aramid fabrics, which have good thermal radiation performance but weigh more than 250g / m 2 , seriously affecting the firefighters' maneuverability and physical strength, increasing the firefighters' forward load and reducing the comfort of the fire suits; ② Metal aluminum composite high temperature resistant base fabric, using the metal material's reflection mechanism of thermal infrared, combines the metal material with the base fabric in the form of a coating to achieve good heat reflection and heat blocking effects, but the aluminum film-coated fabric has poor air permeability and moisture permeability, affecting the comfort of the fire suit fabric. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a lightweight heat radiation proof flame retardant firefighting clothing fabric, so as to improve the comfort of the firefighting clothing at the same time.
[0005] The technical solution adopted by the utility model is:
[0006] A lightweight flame retardant firefighting clothing fabric with heat radiation protection, comprising a three-layer structure formed by three groups of warp and weft yarns of the surface layer, the middle layer and the inner layer, through the inner warp connecting the surface weft and the inner warp connecting the middle weft, with a unit area mass of 200-230g / m 2 The surface layer is a 2 / 1 twill weave, and the middle layer and inner layer are a 1 / 1 plain weave.
[0007] Through the multi-layer structure design, a three-layer three-dimensional structure fabric is formed, and an air layer is formed inside the fabric. The thickness of the fabric is increased, which delays the transfer of heat. The combination of multiple fibers improves the radiation heat protection performance of the surface and inner layers of the fabric. The fabric has a lighter weight, which reduces the burden on firefighters and improves the comfort of the fabric.
[0008] Optionally, the warp yarn arrangement ratio of the surface layer, the middle layer and the inner layer is 19:4:7, and the weft yarn arrangement ratio of the surface layer, the middle layer and the inner layer is 18:4:6.
[0009] Through the arrangement ratio of warp and weft yarns, a fabric structure with dense surface layer and loose middle and inner layers is established. The tightness of the surface layer is large, which reduces the penetration of radiant heat into the fabric. The loose arrangement of the middle and inner layers improves the softness and breathability of the fabric, further improving the comfort of the fabric.
[0010] Optionally, the inner warp connected to the surface weft is a 1 / 2 twill weave, and the inner warp connected to the middle weft is a plain weave.
[0011] Optionally, the yarn count of the surface layer and the inner layer is 42 s / 2-60 s / 2, the single yarn twist coefficient of the surface layer and the inner layer yarn is 310-340, and the single yarn strand coefficient of the surface layer and the inner layer yarn is 420-440.
[0012] Optionally, the middle layer uses 100-300D polyimide fiber filaments.
[0013] Polyimide fiber filaments have high strength, which improves the mechanical properties of the fabric.
[0014] Optionally, the twist of the polyimide fiber filaments in the middle layer is 200-500 twists / m.
[0015] Optionally, the warp density of the fabric is 490-520 strands / 10cm, and the weft density of the fabric is 450-470 strands / 10cm.
[0016] The beneficial effects of the utility model are:
[0017] Through the multi-layer structure design, a three-layer three-dimensional structure fabric is formed. An air layer is formed inside the fabric, the thickness of the fabric is increased, and the heat transfer is delayed. The combination of multiple fibers improves the radiation heat protection performance of the surface and inner layers of the fabric. The high strength of the polyimide fiber filament improves the mechanical properties of the fabric. The fabric has a light weight, which reduces the burden on firefighters and improves the comfort of the fabric. BRIEF DESCRIPTION OF THE DRAWINGS
